Management of Leg Ulcers

Treatment of lower extremity ulcer Lower extremity ulcer is a common symptom of HbSS, but its prevalence varies with geographical distribution. For example, 75% of Jamaican HbSS patients suffer, but only 8 to 10% of South American patients suffer. The underlying cause of lower limb ulcers are bacterial infections caused by cell stenosis, venous insufficiency, excessive vasoconstriction, and impaired autonomic control. In addition, impaired nitric oxide bioavailability and endothelial dysfunction caused by anemia or chronic hypoxia are also relevant.

According to Vowden (2010), effective lower limb ulcer management can be divided into four stages of evaluation, treatment, review of progress, and treatment of ulcer. Hartmann (2008) stated that venous leg ulcers are chronic wounds with low healing tendencies and chronic wounds such as venous leg ulcers cure phase-specifically. Regardless of the type of wound and the extent of tissue loss, each wound healing process progresses in a time overlapping phase and can not separate from each other. In fact, the three stages of wound healing are called washing, granulation and epithelialization.

This article is part of a study on the practice of chronic wound care care based on venous leg ulcer. This article covers all aspects of this specific medical condition, symptoms, cause, sequelae, various treatments in the UK, and costs of NHS treatment of venous leg ulcers. In this study, venous leg ulcers were first introduced and their definition, symptoms, and prevalence in the UK were designed to gain insight into effective wound management practices.

According to information on venous leg ulcers provided by NHS, lower limb ulcers are areas of damaged skin under the knees or feet and take more than six weeks to heal. The most common type of lower extremity ulcer is a venous leg ulcer, which accounts for 80 to 85% of all cases. Treatment costs are high, and early diagnosis and response to treatment are optimal. If the vein of the foot does not function properly, it is called venous insufficiency, causing venous leg ulcers and may be due to major risk factors such as diabetes, obesity, family history and lifestyle. Older leg ulcers are more popular than young people. As Myers (2004, p. 230) pointed out, "women are three times more likely to have venous malfunctioning ulcers than men". One of the main effects of venous leg ulcers is that it is a chronic wound with a poor healing system and a high recurrence rate.
