True about burn ?
|A||Hyperglycemia is seen in early burn|
|B||Child with burns should have damp dressing|
|C||Chemical powder burn should be kept dry|
|D||3rd degree burn are painful|
a. Third-degree burns are full thickness through the epidermis and dermis and are characterized by a hard, leathery eschar that is painless and black, white, or cherry red.
b. No epidermal or dermal appendages remain; thus, these wounds must heal by re-epithelialization from the wound edges.
d. Hypermetabolism develops after severe burns and resuscitation.
e. Alterations in metabolism are seen due in part to the release of catabolic hormones, which include catecholamines, glucocorticoids, and glucagon.
f. Cortisol has similar actions on energy substrates, and it induces insulin resistance, which is additive to the hyperglycemia because of the release of liver glucose.
g. Catecholamines, when combined with glucagon and cortisol, augment glucose release, which could initially be beneficial because glucose is the principal fuel of inflammatory cells, as well as neural tissue.
