The most basic principle of healing a wound is to determine the cause—and then remove it. This is easier said than done, as many wounds have similar characteristics and we don’t always know all the facts leading up to the wound.
The process has been unnecessarily complicated by the recent pressure (no pun intended) to avoid at all costs calling a pressure ulcer a pressure ulcer. I use the term “unnecessarily” because it doesn’t matter what it’s called—a pressure ulcer, decubitus, “de-cube,” or bedsore—because in the end, the general idea is it’s bad news.
So what’s behind the desire to avoid calling it a pressure ulcer? First, a pressure ulcer has traditionally been equated to poor nursing care. As Florence Nightingale, the “Mother of Nursing,” wrote:
“If he has a bedsore, it’s generally not the fault of the disease, but of the nursing.”
No one likes to feel that he or she gave poor care, and as more hospital complications data are available to the public, reports of complications such as pressure ulcers affect people’s perceptions—right or wrong—about the care a hospital delivers.
The second reason gets at the “at all costs” part of the desire. The recent attention given to Medicare’s “present on admission” rule and “never” events has
elevated pressure ulcers high up the chain of “no-no’s” and put the hospital at risk for nonreimbursement. And many private insurers have followed Medicare’s lead in denying coverage for pressure ulcers that occur in the hospital. Unfortunately, all the focus on reimbursement is beginning to challenge even the best wound care experts, who simply want to get the patient’s wound healed.
Pressure from upper management has resulted in experts trying to bargain and rationalize their way out of calling it what it is (a pressure ulcer), instead calling it a bruise, not a deep-tissue injury. Or saying, “This is a shearing ulcer, not a pressure ulcer.” Or, my favorite: “It’s not an ischial pressure ulcer but a diabetic ulcer because the patient is a diabetic.” Wound care experts are being forced to question and doubt themselves because money, quality assurance, and reputation are on the line when an in-house wound is labeled a pressure ulcer.
Like crime scene investigation, determining wound etiology requires us to gather all the facts. Once the facts are in, systematically comparing and contrasting the clinical findings aids differential identification to pin down the type of wound present. It’s important that we assess and investigate all the following when searching for the cause:
•   patient’s medical history
•   recent activities (such as surgery, extensive X-rays, or long emergency-
department waits)
•   comorbidities
•   specific wound characteristics, such as location, distribution, shape, wound bed, and surrounding skin.

Naming the wound is an important first step in intervening. If the wound is caused by pressure, call it a pressure ulcer and jump into action. Remove the cause, heal the wound, and prevent further breakdown. Don’t let yourself be influenced by those who aren’t experts in wound care.

Sherry stands nervously in the doorway, watching several dozen people chat each other up. The sound of her heartbeat threatens to drown out the conversational din. For the people on the other side of the door, this is a networking event. But for Sherry, it seems like a swap meet of business cards.
If Sherry sounds like you, know that you’re not alone. For many people, networking means an awkward evening spent cradling a wine glass in one hand, thrusting a business card at someone with the other hand, and exchanging small talk.

“Hello. My name is…”

Networking is one of the most overused, misunderstood, and underestimated terms in the business world (and yes, that includes health care). Actually, networking is just a newish term for an activity that has been around for millennia. Savvy people have always seen the wisdom of seeking out others who can help them get ahead.
Simply put, networking is an information exchange, a forum for communicating your needs or agenda and, in return, listening and responding to others’ needs or agendas. Good networking requires emotional reciprocity, which means caring about the needs and agendas of the people you network with. Caring about others’ needs is what nurses do, so networking really shouldn’t be that difficult for a nurse.
Think of networking as a great opportunity to make yourself known, gather critical information, and meet people who can help you now and in the future. Through networking, you can make contacts that further your agenda—whether it’s to find
a mentor, get information on a program you’re interested in, change jobs, or advance from your current position.
Networking isn’t just who you know, but who knows you. If you listen to other networkers and give them the resources they seek (as by introducing them to key people or sharing valuable information), they’ll become grateful—and indebted—networking colleagues.

Set a networking goal

At a networking event, the idea isn’t to meet the greatest number of people possible in one evening. It’s to meet the “right” people—those who can help you realize your goal.
When approaching a networking situation, ask yourself, “What do I want this experience to lead to?” You’ll be much more effective if you have a laser-focused goal. The most successful networker isn’t the one who walks away with the most business cards. It’s the one who leaves with the contacts and information he or she had been seeking.

A tale of two networkers

To demonstrate this point, let’s take the case of two wound care specialists, Myrna and Doris—colleagues who’ve carpooled together to a meeting of their professional organization.
Myrna arrives with an agenda and a plan for the evening: She wants to develop a wound care speakers bureau to boost the community profile of staff at her facility. She seeks out several speakers, who give her valuable tips on how to market her expertise. She also shares her vision of a speakers bureau with attendees from other facilities—and is surprised by the support and tips they offer. She leaves the meeting with valuable information that can further her vision. On the way home, she jots down a reminder to send one of the people she met an article he might find helpful. She also makes notes about what she learned tonight, so she can follow up that week. Clearly, Myrna’s networking has been effective.
Doris, on the other hand, goes to the meeting unfocused. She meanders about the room speaking with a lot of attendees, and exchanges a few business cards. But the “Where-do-you-work?” conversations that ensue provide little insight. Although she enjoys the meeting somewhat, she has accomplished little. That’s understandable, as she set out with no goals. She might have been better off spending the night watching television.

Networking etiquette

To succeed at networking, learn networking etiquette. Rule #1: Turn off your cell phone—or at least put the ringer on vibrate. If you absolutely must take a phone call, discreetly leave the room.
More etiquette advice:
• Wear your name tag on your left lapel so you don’t block your name when shaking hands. If you fill out the name tag yourself, print clearly so your name and title are visible from about 5 feet away. That way, others won’t need to squint at your chest to read your name.
• Keep your handshake firm and friendly. Don’t hang on, and don’t pump! Remember to make eye contact, and smile.
• Keep breath mints handy. Networking usually takes place around drinks and food, and the first thing that greets a new contact shouldn’t be the garlic and onion dip.
• Keep your business cards handy (a business card holder is best), but don’t throw them at everyone you meet. Hand your business card to a contact so it’s right side up and facing that person. When someone hands you a business card, take a moment to look at it; then say thank you and carefully put it away. It’s disrespectful to deface a business card, so don’t write on the back of it.

What happens next?

Okay—you’ve set an agenda, attended the networking event without violating etiquette, and made some good contacts. Now what? This is where many people drop the ball. They fail to follow through on the contacts they make and the information they gain. They simply shove the contacts’ business cards into a Rolodex, where they will sit forgotten.
Instead of letting business cards collect dust, develop a system that helps you follow through with your contacts—whether it’s an electronic tool, a simple calendar notation, or a color-coded filing system. Jot down contact information on each
person you met, along with a summary
of your conversations, when you need to follow up, and so forth. Make the system work for you.
Next, follow through with appropriate communication. Send handwritten thank-you notes to the contacts who gave you valuable information or resources—for instance, those who introduced you to a key player or offered to make a phone call on your behalf. If possible, your note should mention how that information worked out for you. (See Seven steps to effective networking by clicking the PDf icon above.)
In the coming weeks, months, or years, keep these relationships alive and thriving by sending tips or information to each contact. If you see a newspaper article or Internet story about a topic a particular contact was interested in, send it to him or her. This shows you’re thinking about that person, and conveys your generosity and willingness to continue a reciprocal relationship.

Make it happen

Networking opportunities can happen anywhere. Don’t wait for them—create them. Pinpoint your goal, identify the key people who can help make it happen—and then network! It’s as simple as picking up the phone, sending an e-mail, or meeting over lunch. With a little effort, networking can be an enjoyable and valuable career resource.

Wound pain can have a profound effect on a person’s life and is one of the most devastating aspects of living with a wound. In addition to pharmaceutical options, wound care clinicians should consider other key aspects of care that can alleviate pain. Here is a checklist to ensure you are thorough in your assessment. (more…)

New wound-swabbing technique detects more bacteria

The new Essen Rotary swabbing technique takes a few seconds longer to perform than traditional techniques, but improves bacterial count accuracy in patients with chronic leg ulcers, according to a study published by Wounds International.
“Evaluation of the Essen Rotary as a new technique for bacterial swabs: Results of a prospective controlled clinical investigation in 50 patients with chronic leg ulcers” reports that Essen Rotary detected significantly more bacteria compared to standard techniques and was the only one to identify five patients with methicillin-resistant Staphylococcus aureus (MRSA), compared to three detected by other techniques.
The Essen Rotary technique samples a larger surface area of the wound, which is beneficial for detecting MRSA.
“The Essen Rotary may become the new gold standard in routinely taken bacteriological swabs especially for MRSA screenings in patients with chronic leg ulcers,” the study authors write.

Reducing HbA1c by less than 1% cuts cardiovascular risk by 45% in patients with type 2 diabetes

A study presented at the American Diabetes Association 72nd Scientific Sessions found lowering HbA1c an average of 0.8% (from a mean of 7.8% to 7.0%, the treatment target) reduced the risk of cardiovascular death by 45% in patients with type
2 diabetes.
The absolute risk of mortality from a cardiovascular event was 9.9 events per 1,000 person-years in patients with decreasing HbA1c compared to 17.8 events in patients with stable or increasing HbA1c.
“HbA1c reduction and risk of cardiovascular diseases in type 2 diabetes: An observational study from the Swedish NDR” examined data from 18,035 patients in the Swedish National Diabetes Register.

CMS revises hospital, nursing home comparison websites

The Centers for Medicare & Medicaid Services (CMS) has enhanced two websites designed to help the public make informed choices about their health care.
Hospital Compare and Nursing Home Compare now have better navigation and new comparison tools. The two sites include data on quality measures, such as frequency of hospital-acquired infections, and allow the user to compare hospitals on these measures.
Improvements include easy-to-use maps for locating hospitals, a new search function that enables the user to input the name of a hospital, and glossaries that are easier to understand. It’s now also possible to access the data on the sites through mobile applications.
CMS maintains the websites, which are helpful for anyone who wants to compare facilities, not just patients on Medicare or Medicaid.
For more information, read the article in Healthcare IT News.

IOM releases report on accelerating new drug and diagnostics development

The Institute of Medicine (IOM) released “Accelerating the development of new drugs and diagnostics: Maximizing the impact of the Cures Acceleration Network—Workshop Summary.” The report is a summary of a forum that brought together members of federal government agencies, the private sector, academia, and advocacy groups to explore options and opportunities in the implementation of Cures Acceleration Network (CAN). The newly developed CAN has the potential to stimulate widespread changes in the National Institutes of Health and drug development in general.

Focus on individualized care—not just reducing swelling—in lymphedema patients

As a result of two extensive literature reviews, a researcher at the University of Missouri found that emphasizing quality of life—not just reducing swelling—is important for patients with lymphedema. Many providers and insurance companies base treatment on the degree of edema, but the volume of fluid doesn’t always correspond with the patients’ discomfort. Instead, an individualized plan of care should be developed.
The researchers found that Complete Decongestive Therapy (CDT), a comprehensive approach for treating lymphedema that includes skin and nail care, exercise, manual lymphatic drainage, and compression, may be the best form of specialized lymphedema management. For more information about CDT, watch for the November/December issue of Wound Care Advisor.

Plague case in Oregon draws national attention

An article about a case of the plague in Oregon has appeared on Huffington Post. A welder contracted the disease as a result of unsuccessfully removing a mouse from a stray cat’s mouth. Part of his hands have, in the words of the article, “darkened to the color of charcoal.” Later tests confirmed the cat had the plague.
Plague cases are rare in the United States. According to the Centers for Disease Control and Prevention, an average of 7 human cases are reported each year, with a range of 1 to 17 cases. Antibiotics have significantly reduced morality. About half of cases occur in people ages 12 to 45.

Use of negative pressure wound therapy with skin grafts

“Optimal use of negative pressure wound therapy for skin grafts,” published by International Wound Journal, reviews expert opinion and scientific evidence related to the use of negative pressure wound therapy with reticulated open-cell foam for securing split-thickness skin grafts.
The article covers wound preparation, treatment criteria and goals, economic value, and case studies. The authors conclude that the therapy has many benefits, but note that future studies are needed “to better measure the expanding treatment goals associated with graft care, including increased patient satisfaction, increased patience compliance and improved clinical outcomes.”

Mechanism for halting healing of venous ulcers identified

Researchers have identified that aberrantly expressed microRNAs inhibit healing of chronic venous ulcers, according to a study in The Journal of Biological Chemistry.
Six microRNAs were plentiful in 10 patients with chronic venous ulcers. The microRNAs target genes important in healing the ulcers. In an article about the study, one of the researchers said, “The more we know about the molecular mechanisms that contribute to [the development of venous ulcers], the more we can rationally develop both diagnostic tools and new therapies.”

Hemodialysis-related foot ulcers not limited to patients with diabetes

Both patients with diabetes and those without are at risk for hemodialysis-related foot ulcers, according to a study published by International Wound Journal.
Researchers assessed 57 patients for ulcer risk factors (peripheral neuropathy, peripheral arterial disease, and foot pathology, such as claw toes, hallux valgus, prominent metatarsal heads, corns, callosities, and nail pathologies) at baseline, and noted mortality 3 years later.
In all, 79% of patients had foot pathology at baseline, and 18% of patients without diabetes had peripheral neuropathy. Peripheral arterial disease was present in 45% of diabetic and 30% of nondiabetic patients. Nearly half (49%) of patients had two or more risk factors. Only 12% of patients had no risk factors. The presence of peripheral arterial disease and peripheral neuropathy increased risk of mortality.
The authors of “Prevalence of risk factors for foot ulceration in a general haemodialysis population” state that the high prevalence of risk factors in nondiabetic patients indicates that they are at risk for developing foot ulcers.

Study identifies risk factors for mortality from MRSA bacteremia

A study in Emerging Infectious Diseases found that older age, living in a nursing home, severe bacteremia, and organ impairment increase the risk of death from methicillin-resistant Staphylococcus aureus (MRSA) bacteremia.
Consultation with a specialist in infectious disease lowers the risk of death, and MRSA strain types weren’t associated with mortality.
“Predicting risk for death from MRSA bacteremia” studied 699 incidents of blood infection from 603 patients who had MRSA bacteremia.

Lymphedema is characterized by regional immune dysfunction, distorted limb contours, and such skin changes as papillomas, hyperkeratosis, and increased girth. The condition may involve the limbs, face, neck, trunk, and external genitals; its effects may include psychological distress. For optimal patient management, clinicians must understand what causes lymphedema and how it’s diagnosed and treated.
This two-part series provides an overview of lymphedema. Part 1 covers etiology, pathology, and diagnosis. Part 2, which will appear in the November-
December issue, will focus on treatment.

Causes of lymphedema

Lymphedema occurs when protein-rich fluid accumulates in the interstitium due to impaired lymphatic function. Proteins, other macromolecular wastes, and water constitute lymphatic loads. These wastes rely on specially structured absorptive and transport structures in peripheral regions for their return to central circulation.
When lymph stasis prevails, inflammatory processes and lymphostatic fibrosis trigger tissue-density changes, further entrapping superficial vessels and accelerating mechanical insufficiency. (See Physiologic changes caused by lymphatic disruption by clicking the PDF icon above.)

Classifying lymphedema

Lymphedema can be primary or secondary. Primary lymphedema either is congenital (present at birth) or arises around puberty. In the vast majority of cases, it is associated with structural changes in the lymphatic system and isn’t associated with another disease or condition. Most structural changes (87%) manifest before age 35 and cause hypoplasia of vessels and nodes. Syndromes involving hyperplasia, node fibrosis, or aplasia also may occur, although they’re much less common. Dysplasia (either hypoplasia, hyperplasia, or aplasia) predisposes drainage regions to inadequate lymph collection, resulting in edema and secondary tissue changes, such as chronic inflammation and reactive fibrosis. Genetic variability in lymphatic constitution may explain why seemingly similar patients receiving the same surgical protocol have different lymphedema risks over time.
Secondary lymphedema stems from a significant insult to lymphatic tissues, as from lymphadenectomy, radiation therapy, trauma, infection, or cancer. It commonly results from direct trauma to regional nodes or vessel structures. Slow degradation of lymphatic function also occurs when adjacent tissues (such as superficial and deep veins) become diseased, when cellulitis occurs, or when accumulations
of adipose or radiation fibrosis mechanical-ly disrupt drainage of skin lymphatics.

Lymphedema stages

Lymphedema progresses in stages, which involve secondary connective-tissue disease combined with disturbed fluid update and transport. These conditions cause a universal and classic clinical picture.
•   Stage 0 (latency stage) is marked by reduced transport capacity and functional reserve. The patient has no visible or palpable edema, but has such subjective complaints as heaviness, tightness, and waterlogged sensations.
•   In Stage 1 edema (reversible lymphedema), edema decreases with elevation. Pitting edema is present, but fibrosis is absent.
•   During Stage 2 (spontaneously irreversible lymphedema), lymphedema doesn’t resolve entirely, although it may fluctuate. Pitting is more pronounced and fibrosis is present.
•   Stage 3 (lymphostatic elephantiasis) is marked by dermal hardening, nonpitting edema, papillomas, hyperkeratosis, and in some cases, extreme girth.

Assessment and diagnosis

Diagnosing lymphedema can be challenging because edema may be associated with other diseases and disorders. For a summary of signs and symptoms, see Clinical findings in lymphedema by clicking the PDF icon above.

Discomfort and skin appearance

Lymphedema rarely causes pain because the skin accommodates gradual, insidious fluid accumulation. However, secondary orthopedic discomfort may result from increased weight of the affected limb due to deconditioning or decreased range of motion.
Because lymphedema usually progresses slowly, gravity and centrifugal forces pull fluids toward distal limb areas, causing an entrenched, stubborn pitting edema. Later, further valvular incompetence contributes to worsening distal edema in the fingers, toes, and dorsal regions of the hand and foot. Prominent lower-extremity structures, such as the malleolus, patella, tibia, anterior tibialis tendon, and Achilles tendon, become progressively less distinct. This creates a columnar limb appearance; the swollen limb has the same girth from distal to proximal aspects, unlike the natural cone shape of a normal limb.
Lymphatic failure doesn’t tax the venous system, so skin color remains normal. Blood supply remains patent, helping to prevent secondary ulcers.

Severity

Lymphedema severity correlates directly with such factors as onset of the condition and extent of cancer therapy, if given (number of nodes resected, number of positive nodes, and use of radiotherapy). Lymphedema may worsen with a greater number of infection episodes, weight gain, injury, diuretics, limb disuse, pneumatic compression therapy (when used for pure lymphedema), and ill-fitting compression garments. The single most important contributor to increasing lymphedema severity is lack of patient education, which can result in improper treatment or none at all.

Opportunistic infections

Lymphedema causes regional immune suppression and leads to an increase in opportunistic infections such as cellulitis. As skin integrity suffers, scaling and dryness allow resident skin pathogens (such as streptococci and staphylococci) to gain access through the defective skin barrier into protein-rich interstitial fluid, creating a medium favorable to bacterial colonization. Lymphocyte migration decreases, and dissected or irradiated nodal sites are slow to detect invaders. Furthermore, stagnant lymph promotes further delays in the immune response. Patients with opportunistic infections may exhibit high fever, local erythema, regional hypersensitivity or acute pain, flulike symptoms, and rapidly advancing “map-like” borders in the skin.

Differential diagnosis

Several methods can aid differential diagnosis.
Clinical findings. Lymphedema can be diagnosed from patient history, physical examination, palpation, and inspection. Trauma to lymph nodes (each of which governs a distinct body region) decreases the transport capacity of lymph formed in that region, in turn causing local swelling (lymphedema). Trauma to the axillary or inguinal lymph nodes, which exist on both the left and right of the body and in both the upper and lower regions, predisposes these quadrants to swelling. Therefore, if lymph nodes on only one side are damaged, lymphedema occurs only on that side of the body. Using the universal characteristics cited above as a guide, while ruling out cancer recurrence, acute deep vein thrombosis, or plasma protein abnormalities, yields sufficient data to form a diagnosis.
Imaging. Lymphography involves subcutaneous injection of a lymph vessel–
specific dye (Patent Blue V), followed by X-ray. Although it provides high-resolution images of lymphatic structures, this technique is invasive, painful, damaging to lymphatics, and potentially lethal—and therefore is no longer recommended.
Lymphangioscintigraphy (LAS) uses interdigital subcutaneous injection of protein-labeled radioisotopes, followed by
imaging at specific intervals to gather information about uptake and transport time. Images are hazy and false-negatives are common, so well-trained radiotherapists familiar with lymphology and lymphedema should administer and interpret the test. Also, experts don’t agree on standard criteria for LAS administration, so measures may not be similarly conclusive.
Limb-measuring instruments and methods. Serial measurement of affected limb circumference using a standard garment tape measure is the most widely accessible approach. Intra-rater reliability is comparable to that of currently used tools; however, these methods can’t be used for early detection, for screening, or when various raters are used to assess the same patient. Circumferences are measured at four points and are considered positive if a distance of 2 cm or more separates the involved from uninvolved extremity in comparison. Water displacement techniques for limb-volume calculation, although accurate, are impractical in most clinical settings and rarely used.
Various devices have been used to obtain measurements. For instance, the Perometer® uses optoelectronic volumetry. By scanning the limb with infrared beams circumferentially, the device accurately records girth at 4-mm intervals along the limb length and transmits these measurements to a computer. The Perometer is used mainly in the research setting. Preoperative and postoperative measurements at intervals can detect lymphedema early.
Impedimed XCA® uses bioelectrical
impedance to calculate ratios of intracellular to extracellular fluid. A weak electrical current is passed through affected and unaffected limbs, allowing comparison of results. Impedance is lower in edematous tissue, supporting an accurate diagnosis.

Next step: Treatment

Once a diagnosis is made, the next step is treatment. Part 2 of this series covers lymphedema treatment.

Every year, thousands of people of all ages have ostomy surgery in the United States. That means no matter where you work, you’re likely to care for patients with new ostomies and teach them to care for themselves. (See Why patients need ostomy surgery by clicking the PDF icon above.)
These patients present two challenges: staying up-to-date on ostomy equipment and procedures and having only 3 to 5 days after surgery to teach basic ostomy care to patients who are unlikely to be physically or emotionally ready to learn. This review and update of ostomy care should help you meet both challenges. Let’s start with the common types of stomas and ostomies.

Reviewing stoma types

The three common types of stomas are the end stoma, loop stoma, and double-barrel stoma. The patient’s surgeon decides on the most appropriate type based on the disease or injury, the amount of intestine available, and the patient’s health status.
To create an end stoma, the most common type, a surgeon creates a small opening in the abdominal wall, then resects the intestine and pulls it through the opening. Next, the surgeon turns the end of the intestine onto itself—somewhat like cuffing a sock—and sutures the stoma to the skin. Next to the stoma, the surgeon may create a mucous fistula, which secretes mucus from the nonfunctioning portion of the intestine.
A loop stoma is usually created for a temporary ostomy. The surgeon creates a small opening in the abdominal wall and pulls a loop of intestine through it. With an external rod or bridge placed under the loop to keep it from slipping back into the peritoneal cavity, the surgeon cuts the top of the loop to form the apex of the stoma. Next, the surgeon everts the intestine around the opening and sutures the stoma edges to the skin. After a few days, the rod is removed, and the stoma stays above skin level on its own.
Double-barrel stomas aren’t common in adults, but they are used frequently in neonates. For this type, a surgeon cuts through the bowel to create two separate end stomas, one to evacuate stool and the other to evacuate mucus. The two stomas can be placed next to each other, so one pouching system can be used for both. If the stomas are further apart, the patient may need two pouches. If mucus secretions are slight, you may be able to apply a nonadherent dressing after gently cleaning the stoma and peristomal skin, instead of using a pouch.
An ideal stoma protrudes above the skin surface and has a flat peristomal skin surface that allows the ostomy barrier to adhere to it. (See Characteristics of an ideal stoma by clicking the PDF icon above.) A healthy stoma is red and moist and looks like gum tissue. In fact, the entire alimentary canal from mouth to anus has the same type of tissue. Keep in mind that while cleaning a stoma, you’ll commonly see a small amount of bleeding, just as your gums may bleed when you brush your teeth too vigorously. If you note excessive bleeding, report it immediately.

Reviewing types of ostomies

The three most common types of ostomies you’ll see are a colostomy, an ileostomy, and a urostomy.
A surgeon creates a colostomy by making an opening in the large intestine and connecting it to the stoma. The location of the surgical opening will affect the consistency of the stool exiting the body through the stoma: The lower the opening, the firmer the consistency. A colostomy produces flatus because of the high bacterial content in the large intestine. A colostomy can be temporary or permanent, depending on the diagnosis and the patient’s ability to heal.
To create an ileostomy, a surgeon makes an opening in the small intestine and forms a stoma. Patients with ileostomies are prone to dehydration because a large amount of enzymatic fluid is discharged through the ileostomy instead of being absorbed in the disconnected large intestine. Teach your patient to be alert for the signs and symptoms
of dehydration—thirst; decreased urination; darker, concentrated urine; warm, flushed skin; fever; and malaise. Also, warn the patient to keep enzymatic effluent off the skin because it can quickly cause skin breakdown. As with a colostomy, an ileostomy may be temporary or permanent.
To create a urostomy, a surgeon removes the diseased bladder and uses a portion of resected small intestine to create a conduit. The ureters, which were connected to the bladder, are sutured into the resected small intestine so urine can exit the body through the stoma. Urostomies are permanent.

Choosing the right pouching system

An ostomy pouching system has two parts: an adhesive barrier that attaches to the skin around the stoma and a pouch connected to the barrier that collects effluent. Determining the right ostomy pouching system for your patients will depend on their needs and preferences. Let’s look at some of the important choices.
A pouching system may come in one or two pieces. With one-piece systems, the barrier (also called the wafer, flange, or baseplate) and pouch come as a single unit. (See One- and two-piece ostomy pouching systems by clicking the PDF icon above.) One-piece systems are easier to apply and more flexible. Plus, they’re flatter and thus more discreet.
With two-piece systems, the barrier and pouch are separate components that must be attached. Depending on the product, the patient may need to press the pouch onto the barrier or use a locking ring mechanism or an adhesive coupling system. Two-piece systems allow the patient to remove the pouch without removing the barrier. Also, a patient can apply a smaller pouch, such as a stoma cap or close-ended pouch, before exercise or intimate relations.
Today, ostomy pouching systems offer many options that weren’t available just a few years ago—options such as built-in, varying levels of convexity and integrated closures. Skin-friendly barriers now eliminate the need for accessory products, such as skin prep, ostomy powder, and stoma paste. By knowing the new options, you can help simplify the pouch application process for your patient and increase patient satisfaction.

Selecting barriers

Barriers may be cut-to-fit or precut. Cut-to-fit barriers are used during the postoperative period while the stoma size is changing and for oval or irregularly shaped stomas. Precut sizes are convenient for round stomas after they stabilize.
The choice of a barrier also depends on abdominal contours and the effluent consistency. A standard-wear barrier is appropriate for thicker output. An extended-wear barrier is better for loose or watery output and for problematic ostomies.
Convex barriers can be used to push down the peristomal skin and help the stoma project into the pouch. These barriers help ensure that the effluent goes into the pouch and not between the skin and the barrier, causing leakage.
For ostomies that are difficult to manage and frequently leak, you may select an ostomy belt. This device helps secure a convex pouching system by increasing its pressure. The plastic hooks at the end of the belt attach to the belt loops of the pouching system. Depending on the manufacturer, the belt loops may be on the barrier or the pouch.

Selecting pouches

Pouches can be transparent or opaque. Transparent pouches allow you to see the stoma postoperatively and allow patients to watch as they place the pouch over the stoma. Opaque pouches, of course, have the advantage of concealing the effluent.
Some pouches have filters. Colostomy patients usually prefer filtered pouches because they eliminate the need to burp the pouch to remove gas. Ileostomy output is usually watery, so the charcoal filters may get wet and quit working.
The appropriate type of pouch closure also varies, depending on the type of output and the patient’s needs and preferences. A patient with a colostomy or ileostomy needs a drainable pouch. Newer clamps and integrated closures can make closing the pouch easier for the patient.
Close-ended pouches are available for patients who empty their pouch once or twice a day. Reimbursement guidelines for Medicare, which most insurance companies follow, allow 60 close-ended pouches a month. Thus, someone who empties once or twice a day will have enough pouches.
Patients with urostomies use pouches with spigots on the end to allow for urine drainage.
Urostomy pouches can be connected to a continuous urinary drainage bag at bedtime or to a leg bag during the day for those in a wheelchair.

Dealing with complications

Report the following postoperative complications to the surgeon and the ostomy clinician caring for the patient:
• allergic reaction
• candidiasis
• contact dermatitis
• folliculitis
• ischemic or necrotic stoma
• mechanical irritation
• mucocutaneous separation
• parastomal hernia
• prolapse.

Many complications result from surgical technique or the patient’s disease status, but complications also result from an incorrect fit or an ostomy that frequently leaks. To determine why and where leakage occurred, examine the back of the barrier. If leakage results from a flush or recessed stoma or an irregular surface around the stoma, the patient may need a convex barrier. Or the patient may need a convex barrier and an ostomy belt.
Remember that a firm abdomen requires a soft, flexible barrier that conforms to the abdominal contours. A soft belly, on the other hand, may need the rigidity of a convex barrier to help the stoma empty into the pouch.
For weepy, extremely denuded skin, apply ostomy powder, brush off the excess, and dab an alcohol-free skin sealant, such as No-Sting by 3M, on the area. Allow the area to air-dry before applying the barrier.

Discharge planning and patient teaching

Because the postoperative length of stay is short, start preparing for discharge and teaching the pouch-change procedure at your first hospital encounter with the patient. Teaching the patient at each encounter creates a continuum of care throughout hospitalization and recovery. If possible, include the caregiver. (See Teaching your patient to change an ostomy pouch by clicking the PDF icon above.) Before discharge, give the patient two or three ostomy pouches to take home, step-by-step printed instructions on applying pouches, a list of supplies the patient will need, and a list of ostomy product suppliers in the area.
Also, teach the patient about complications, activity, diet, and drug therapy and provide the names of local support groups. (See Finding support by clicking the PDF icon above.)

Complications at home

Tell the patient to call the physician if any of the following occurs: fever, increased pain or discomfort, diarrhea, dehydration, or signs and symptoms of infection at the surgical site. The patient should also call the physician if there’s no output from the stoma for more than 24 hours.
Patients with urostomies who develop the following signs and symptoms may have a urinary tract infection: fever, chills, abdominal or retroperitoneal pain, and bloody, cloudy, or foul-smelling urine. Clear urine with mucus shreds is normal.

Increasing activity

Explain that after surgery the patient should feel a little bit stronger every day. Teach the patient to alternate rest and activity periods and to increase the activity period a little each day while building endurance. Refer the patient to the physician for clearance to resume exercise and sexual relations.

Dietary considerations

After ostomy surgery, your patient will start on a clear liquid diet and progress to a normal, preoperative diet. The patient should reintroduce one food at a time to help determine if it’s well tolerated. High-fiber foods should be introduced slowly.
Tell your patient to expect his or her body to tolerate the food as it did before surgery: if onions caused gas before surgery, they will do so after surgery, too, but the stoma will expel the gas. Make the patient aware of other gas-forming foods, such as hard-boiled eggs, spicy foods, fish, dried beans, carbonated beverages, and beer.
Tell the patient to chew food well and to drink plenty of liquids, which will prevent blockage. Explain the importance of hydration to avoid constipation, dehydration, and urinary tract infection. To prevent dehydration, ileostomy patients who are not on fluid restriction should drink 64 ounces of fluid a day. Teach these patients to replace fluids by drinking a glass of water every time they empty their pouches.

Drug therapy

Tell the patient to adhere to the prescribed regimen and to call the physician before using any new drugs. Instruct patients with ileostomies not to take laxatives because they may become dehydrated. These patients should tell their pharmacist that they have an ileostomy, so the proper form of prescription drugs can be ordered. Extended-release tablets will not break down in time and may be found in the pouch.

Rewarding work

Keeping up with the changes in ostomy equipment and care and teaching new ostomy patients the skills they need can be challenging. But helping these patients regain the confidence and learn the skills they need to improve their quality of life makes the rewards much greater than the challenges.

In the current healthcare environment, wound care practitioners need to capitalize on all available reimbursement avenues for care delivery and wound care supplies and dressings. And when it comes to reimbursement, there’s one constant: The rules change constantly. Whether these changes always benefit the patient is questionable. Nowhere is this more evident than in acute-care settings. Clinicians constantly are challenged to make sure their patient-care decisions comply with current Medicare reimbursement guidelines. (And if you’re not sure about today’s guidelines, be prepared for the guidelines to change tomorrow.) (more…)

Necrotizing fasciitis (NF) results from an infection that attacks the fascia and subcutaneous tissues. The primary bacterial etiology is group A streptococcus, a facultative anaerobic bacterium. However, other bacteria may contribute. Sometimes called the “flesh-eating” disease because of the potentially devastating effect on the afflicted patient, NF can be monomicrobial or polymicrobial.

The four typical settings for NF are:

surgical bowel or abdominal trauma surgery
pressure ulcer and perianal abscess
injection sites (especially in drug users)
Bartholin abscess or minor vulvovaginal infection.

Because of the rapid course and ravaging nature of acute NF, clinicians must maintain a high index of suspicion if the patient has suggestive signs and symptoms. In 1990, puppeteer Jim Henson (best known for creating the Muppets) died from NF. At that time, little was known about the progression of group A streptococcal infection.
The disease can quickly cause death, so starting immediate treatment is even more crucial than confirming the diagnosis. Once the disease is suspected, antibiotics must be given immediately and the patient must be prepared for surgery at once. NF spreads rapidly, capable of progressing from a small lesion to death in days to weeks. Thus, delayed diagnosis increases the risk of death. Lack of knowledge about the disease and inability to recognize it promptly are the main reasons many victims die. This article can improve your knowledge base.

Overview

NF was discovered in 1871 by Joseph Jones, a Confederate Army surgeon. At that time, it was called hemolytic streptococcal gangrene, nonclostridial gas gangrene, nonclostridial crepitant cellulitis, necrotizing or gangrenous erysipelas, necrotizing cellulitis, bacterial synergistic gangrene, or synergistic necrotizing cellulitis.
NF involves the fascia, muscle compartments, or both. It can affect not only the muscle fascia but the superficial fascia. NF and cellulitis differ in the amount of tissue involved and extent of tissue involvement.
The most common areas of infection are the abdominal wall, perineum, and extremities. When NF affects the perineum and scrotum, it’s called Fournier gangrene, after the French dermatologist and virologist Alfred Jean Fournier.
The most common causes are trauma, surgery, and insect bites. The disease can affect persons of any age. Such comorbidities as diabetes, chronic renal failure, immunosuppressive therapy, hypertension, obesity, and malnutrition increase susceptibility.

Pathophysiology

NF falls into four classifications based on wound microbiology. Type 1, the most common, involves polymicrobial bacteria. Type 2 results from trauma and is associated with comorbidities. Type 3, rare in this country, stems from gram-negative marine bacteria. Type 4 is a fungal infection occurring mostly in immunocompromised persons. (See Comparing types of necrotizing fasciitis by clicking the PDF icon above.)

Disease progression

The four types of NF progress in a similar way. Bacteria secrete pyrogenic exotoxin A, which stimulates cytokines. These cytokines damage the endothelial lining; fluid then leaks into the extravascular space.
M proteins in streptococci and β-hemolytic streptococci exacerbate the immune reaction by inhibiting phagocytosis of polymorphonuclear leukocytes and normal neutrophil chemotaxis. As the immune reaction increases, blood vessels dilate, allowing toxins to leak through vessel walls, which in turn decreases blood flow. As the cascade continues, hypoxic conditions cause facultative aerobic organisms to grow and become anaerobic. These bacteria exacerbate destruction of surrounding cells and lead to release of carbon dioxide, water, hydrogen, nitrogen, hydrogen sulfide, and methane. As the infection continues to progress, toxins spread throughout the bloodstream and the patient becomes septic.

Assessment

Obtain the patient’s medical history and description of the wound. Determine when the changes first appeared and whether the affected area seemed to get worse recently.
In all NF types, patients commonly present with a small, painful area (possibly with entry marks) but no other signs or symptoms. The wound may appear as a bulla, cellulitis, or dermatitis, representing an infection developing in underlying tissues. The skin may have a wooden-hard feel as the infection progresses to the subcutaneous space and causes necrosis. The wound becomes discolored and necrotic; drainage is rare until surgical debridement begins. The patient quickly develops fever, chills, nausea, and vomiting. As NF progresses, bullae become dark purple with darkened edges; the patient grows disoriented and lethargic, and organ failure and respiratory failure
ensue. Without treatment, the patient dies.

Diagnosis

Diagnostic tests usually include magnetic resonance imaging, complete blood count with differential, comprehensive metabolic panel, and cultures. (See Diagnostic findings in necrotizing fasciitis by clicking the PDF icon above.)

Treatment

Immediate surgical debridement and broad-spectrum antibiotics are needed to stop the immune response to infection. Clindamycin, gentamicin, penicillin, or metronidazole may be given alone or in combination until culture results are available. Supportive care includes total parenteral nutrition for nutritional support, I.V. fluids, and oxygen. Limb amputation should be done only as a last resort.
Surgical debridement involves penetrating deep into the fascia and removing all necrotic tissue. After the first debridement, release of “dishwater fluid” may occur.
Administering hyperbaric oxygen therapy (HBOT) after the first debridement increases tissue oxygenation, thus reducing tissue destruction by anaerobic bacteria. During HBOT (usually given as a 90-minute treatment), the patient breathes 100% oxygen in an environment of increasing atmospheric pressure.
HBOT should be given in conjunction with surgical debridement (usually after each debridement) and should continue until necrotic tissue ceases and cell destruction stops. HBOT also promotes collagen synthesis and neoangiogenesis (new blood vessel growth), which boosts blood supply and oxygen to tissues.
Adverse effects of HBOT include ear pain, oxygen toxicity, and seizures. Ear pain can be minimized by swallowing or yawning. If the patient continues to have ear pain, ear tubes may be inserted by an otolaryngologist. During HBOT, air breaks (intervals of breathing room air) are important in controlling oxygen toxicity (the main cause of seizures).
Throughout the HBOT treatment period, wound dressings must be simple. Well-moistened gauze dressings and an abdominal pad provide good support. Once necrotic destruction occurs, dressings depend on wound size and the need to fill cavities. The patient may require a diverting colostomy, depending on wound
location and the amount of uncontrolled diarrhea. Blood glucose levels must be monitored before and after HBOT, as this treatment affects blood glucose.

Supportive care and follow-up treatment

During initial treatment, patients need supportive care and monitoring. Once they’re out of danger, begin teaching them how to prevent NF recurrences. Advise them to control blood glucose levels, keeping the glycated hemoglobin (HbA1c) level to 7% or less. Caution patients to keep needles capped until use and not to reuse needles. Instruct them to clean the skin thoroughly before blood glucose testing or insulin injection, and to use alcohol pads to clean the area afterward.
Before discharge, help arrange the patient’s aftercare, including home health care for wound management and teaching, social services to promote adjustment to lifestyle changes and financial concerns, and physical therapy to help rebuild strength and promote the return to optimal physical health. One helpful patient resource is the National Necrotizing Fasciitis Foundation. The Centers for Disease Control and Prevention section on necrotizing fasciitis includes “Common sense and great wound care are the best ways to prevent a bacterial skin infection.”
The life-threatening nature of NF, scarring caused by the disease, and in some cases the need for limb amputation can alter the patient’s attitude and viewpoint, so be sure to take a holistic approach when dealing with the patient and family. Today, NF has a much better survival rate than 2 decades ago when Jim Henson died. In my practice, I’ve seen four NF cases. Thanks to early identification, good wound care, and HBOT, these patients suffered only minimal damage.
