In microangiopathy, neuropathy and autoregulation of capillaries leads to poor perfusion of tissues, especially wound base. When pressure is placed on the skin, the skin is damaged and is unable to be repaired due to the lack of blood perfusing the tissue. The wound has a characteristic deep, punched out look, often extending down to the ...
Pressure ulcers can trigger other ailments, cause considerable suffering, and can be expensive to treat. Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
Chronic wound healing may be compromised by coexisting underlying conditions, such as venous valve backflow, peripheral vascular disease, uncontrolled edema and diabetes mellitus. If wound pain is not assessed and documented it may be ignored and/or not addressed properly. It is important to remember that increased wound pain may be an ...
Schematic diagram of the medial side of the elbow showing the ulnar nerve passing through the cubital tunnel. Chronic compression of the ulnar nerve in the cubital tunnel is known as cubital tunnel syndrome. [4] There are several sites of possible compression, traction or friction of the ulnar nerve as it courses behind the elbow. [5]
Treatment is typically to avoid the ulcer getting infected, remove any excess discharge, maintain a moist wound environment, control the edema, and ease pain caused by nerve and tissue damage. Topical antibiotics are normally used to prevent the ulcer getting infected, and the wound or ulcer is usually kept clear of dead tissue through surgical ...
When debridement is necessary, wounds are left open so that serial debridements may be performed over the course of the wound's healing. [7] Antibiotic choice should be guided by deep tissue culture, severity of the infection, presence or absence of osteomyelitis, prior antibiotic treatment, and previous or current MRSA infection.

Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
