The goal of wound-bed preparation is to create a stable, well-vascularized environment that aids healing of chronic wounds. Without proper preparation, even the most expensive wound-care products and devices are unlikely to produce positive outcomes.
To best prepare the wound bed, you need to understand wound healing physiology and wound care basics, as well as how to evaluate the patient’s overall health and manage wounds that don’t respond to treatment. (See Normal wound healing.) (more…)

Editor’s note: This article is the second in a two-part series on palliative wound care. For the first part, click here.
By preventing and relieving suffering, palliative care improves the quality of life for patients facing problems associated with life-threatening illness. This care approach emphasizes early identification, impeccable assessment, and treatment of pain and other issues—physical, psychosocial, and spiritual. (more…)

Jan Smith, age 59, is admitted to the coronary intensive care unit with an acute inferior myocardial infarction (MI). Recently diagnosed with hypertension and hyperlipidemia, she smokes a pack and a half of cigarettes daily. She reports she has always been healthy and can’t believe she has had a heart attack. (Note: Name is fictitious.)
On physical exam, the cardiologist finds decreased femoral pulses bilaterally and recommends immediate cardiac catheterization. Fortunately, primary percutaneous coronary intervention (PCI) is readily available at this hospital. PCI is the preferred reperfusion method when it can be provided by skilled cardiologists in a timely manner. (more…)

Since its introduction almost 20 years ago, negative-pressure wound therapy (NPWT) has become a leading technology in the care and management of acute, chronic, dehisced, traumatic wounds; pressure ulcers; diabetic ulcers; orthopedic trauma; skin flaps; and grafts. NPWT applies controlled suction to a wound using a suction pump that delivers intermittent, continuous, or variable negative pressure evenly through a wound filler (foam or gauze). Drainage tubing adheres to an occlusive transparent dressing; drainage is removed through the tubing into a collection canister. NWPT increases local vascularity and oxygenation of the wound bed and reduces edema by removing wound fluid, exudate, and bacteria. (more…)

Venous disease, which encompasses all conditions caused by or related to diseased or abnormal veins, affects about 15% of adults. When mild, it rarely poses a problem, but as it worsens, it can become crippling and chronic.
Chronic venous disease often is overlooked by primary and cardiovascular care providers, who underestimate its magnitude and impact. Chronic venous insufficiency (CVI) causes hypertension in the venous system of the legs, leading to various pathologies that involve pain, swelling, edema, skin changes, stasis dermatitis, and ulcers. An estimated 1% of the U.S. population suffers from venous stasis ulcers (VSUs). Causes of VSUs include inflammatory processes resulting in leukocyte activation, endothelial damage, platelet aggregation, and intracellular edema. Preventing VSUs is the most important aspect of CVI management. (more…)
By combining bioactive peptides, researchers have successfully stimulated wound healing in an in vitro and in vivo study. The studies, published in PLoS ONE, show that the combination of two peptides stimulates growth of blood vessels and promotes tissue re-growth of tissue. Further research into these peptides could potentially lead to new therapies for chronic and acute wounds.
The researchers evaluated a newly-created peptide, UN3, in pre-clinical models with the goal of simulating impaired wound healing as in patients suffering from peripheral vascular diseases or uncontrolled diabetes. They discovered that the peptide increased the development of blood vessel walls by 50%, with an 250% increase in blood vessel growth, and a 300% increase in cell migration in response to the injury.
