Describe a first degree burn |
1st degree- confined to the epithelial layer of the skin, produces erythema and mild discomfort. Injured area is red and blisters are usually not seen on exam. Full function remains, reduced by pain. Symptoms of swelling and pain are short in duration. Topical application of moisturiser to exposed surface of burned area reduces pain. Reepitheliastion begins within 48 hours. No restrictive scar results. |

Describe a 2nd degree burn |
Penetrates into the dermis Can be classified into superficial or deep Superficial second degree burns involves the upper level of the dermis and is expected to reepitheliaise within 10 to 14 days with topical wound care Appearance of the burn is characterised by blisters, intact or ruptured, a thin eshar and severe pain Periphery shows an erythema as the level of the burn becomes increasingly superficial Deep 2nd degree burns extend to the depth of the dermis, injuring a greater concentration of rhe adrenal hair follicles and sweat glands This diminishes the ability for reepithelialisation and results in delayed healing - taking between 14 and 21 days to completion Absence of blisters and sometimes a moderate thickness of eschar Immediate pain is less intense because the superfical nerve endings are injured by the burn at this depth Quality of healing after these depth injuries can be poor, increasing the risk of later hypertrophy and secondary scar contracture |
