Wound types and Management
'Wound care has, in the past, not been well managed because of the limited understanding of the healing process and the inadequate range of dressing materials available. Wound management has now come full circle, back to Hippocrates' principle and dressings are being developed to provide the ideal environment for nature to do its work'.
The primary function of normal intact skin is that it can control microbial populations living on skin surface from entering underlying layers or organs and thus protects the body from pathogens. Exposure of subcutaneous tissue with a wound provides a moist and warm environment for microbial organisms. However factors such as wound type, depth, and location, quality, level of tissue perfusion and anti-microbial efficacy or resistance is important for examining microbial effects on wounds. Wounds are broadly categorized as either acute or chronic. Acute wounds are caused by external damage to intact skin and include surgical wounds, bites, burns, minor cuts and abrasions, and more severe traumatic wounds such as lacerations and those caused by crush or gunshot injuries .Acute wounds are expected to heal within a predictable and specified time frame and with minimal intervention although in severe cases such as gunshot wounds, anti-microbial therapy or surgical intervention may be necessary. In contrast, chronic wounds are most frequently caused by endogenous mechanisms associated with a predisposing condition that ultimately compromises the integrity of dermal and epidermal tissue Pathophysiological abnormalities that may predispose to the formation of chronic wounds such as leg ulcers, foot ulcers, and pressure sores include compromised tissue perfusion as a...
