Terms | Definitions |
|---|---|
 thermal burns | result from exposure to dry heat, (flames) or moist heat (steam and hot lquids) |
| chemical | caused by direct skin contact with either acid or alkaline agents |
| electrical | depends on the type and duration of current and amount of voltage |
| radiation | usually associated with sunburn or radiation treatment for cancer |
| thermal | which type of burns are most common and occu mostly in children and older adults |
| electrical | these types of burns have entry and exit wounds,often small |
| radiation | these type of burns tend to be superficial |
| superficial | characteristic of which thickness burns (partial, superficial ,full thickness) only epidermis lost, skin appears pink to red and dry and may have local edema, skin function and pain are present, manifesations at burn site include pain and local edema,clean regularly use topical agent of choice, no outer layer peeling and will take 3-6 days to heel |
| partial | characteristic of which thickness burns (partial, superficial ,full)epidermis and dermis lost,fluid filled blisters present skin is bright pink or red with superficial partial thickness. pale, waxy white with deep partial thickness burnsskin function is absent but pain is present , manifestations at burn site inclue severe pain ,swelling, and weeping of flud,clean regulary and choose topical agent of choice , may require skin grafting of deep partial thickness burns scarring may occur in deep burns takes 14 to greater thn 21 days to heal |
| full | characteristic of which thickness burns (partial, superficial ,full thickness)loss of epidermis, dermis and underlying tissue, skin is waxy white; dry leathery and charredskin function and pain are absent,manifestations at the site are little pain and edema, clean regularly use topical agent of choice, skin substitutes, excision of eschar,skin grafting for tx. scarring of grafted areaand rquires skin grafting to heel |
| first | what degree burn is superficial thickness burns |
| second | what degree of burns is partial thickness burns |
| third | what degree of burns is full thickness burns |
| rules of nine | estimates extent of burn |
| superficial partial thickness | this burn involves the entire dermis |
| partial thickness | these burns are subdivided into superficial or deep |
| deep partial thickness | these burns involve the entire epidermis plus hair follicles, but sebaceous glands and epidrmal sweat glands remain intact |
| cardiovascular burns | these burns:within minutes of the burn , there is a loss of cell wall integrity at the injury site and in the capillary bed,this causes a massive amount of fluid to shift from the intracellular spaceinto the interstitial space,fluid leaks from the capillaries at the burn site and throughout body results in hypovolemic shock (BURN SHOCK) |
| blood clots | the loss of intravascular volume causes an increase in blood viscosity that increases th risk for .....? |
| vasoconstriction | occurs as the vascular system attempts to compensate for fluid loss |
| platelet aggregation, white blood cell | abnormal ___ ___and ___ ___ ___ accumlation result in ischemia, and eventual thrombosis in the deeper tissue below the burn. |
| hemolyzed | red blood cells are ___ due to direct damage from the burn |
| hemoconcentration | because plasma flud is lost rather than RBC;s ____occurs wh'sich is seen as elevated white and RBC |
| hypovolemia, edema | the leakage of fliuid into the interstitial spaces compromises the lymphatic system ,resulting in intravascular and at the burn site. |
| false | T/F cells can maintain normal electrolytes, resulting in excess NA+ w/in the cell and excess K+ o/side the cell. |
| true | T/F if the microcirculation of the skin remains intact during burning, it cools and protects deeper layers of skin. |
| true | T/F if the microcirculation of the skin is lost, it continues to burn the skin even if the heat source is removed |
| compartment syndrome | when circumferential burns and edema occur together this may result |
| curling's ulcer | an accute ulcerationof the stomache or duodenum that may form after a burn injury |
| curlings ulcer | abdominal pain, acidic gastric ph levels, hematamesis(vomitting blood) and occult blood may indicate the presence of.......? |
| paralytic ileus | may occur secondary to burn trauma. lack of intestinal motilitiy leads to gastric distention , nausea, vomitting, and hematamesis. |
| hemoglobinuria | dark brown concentrated urine may lead to |
| hemoglobinuria | result of release of large amounts of dead or damaged erythrocytes after a major burn (can lead to renal failure) |
| cortisol | is released due to the stress of the burn injury , which depresses the immune system and increases th risk of infection |
| ebb phase and flow phase | 2 distinct metabolic phases occur as body responds to burn injury what are they..... |
| ebb phase | (1st phase) lasting suring the first 3 days of the injury, is manifested by decreased oxygen consumption, fluid imbalance, shock and inadequate circulating volume (these responses protect the body from the initial impact of the body) |
| flow phase | (2nd phase) |
