First degree burn – involves only the epidermis. Mild pain and erythema but no blisters. Skin functions remain intact. 2.Second degree burn – destroys the epidermis and part of the dermis. Some skin functions lost. Redness, blister formation, edema, and pain. Scarring my result. 3.Third degree burn or full thickness burn – destroys the epidermis, dermis, and SQ layer. Most skin functions are lost. Such burns vary in appearance from marble-white to mahogany coloured to charred, dry wounds. Edema, and the burned region is numb due to sensory nerve endings destroyed. Regeneration occurs slowly. May require skin grafting to promote healing and to minimize scaring. -Systemic effects of a major burn are a greater threat to life, may include: oA large loss of water, plasma, and plasma proteins, which causes shockoBacterial infectionoReduced circulation of bloodoDecreased production of urine oDiminished immune response. -Rules of nine to estimate the surface area of affected by a burn in an adult. iii.Pressure ulcer - also known as decubitus ulcer or bedsores, are caused by a constant deficiency of blood flow to tissues. Typically the affected tissue overlies a bony projection that has been subjected toprolonged pressure against an object such as a bed, cast or splint. oBlistering may indicate superficial damageoA reddish-blue discolouration may indicate deep tissue damageoProlonged pressure causes tissue ulceration. Small breaks in the epidermis become infected, and thesensitive SQ layer and deeper tissue are damaged. Eventually the tissue dies.oCan be prevented with proper care but can develop very quickly in patients very old or very ill.
