|---|---|
| What is the role of the skin? | Prevents heat and water loss as well as invasion by bacteria |
| What is the result of a burn? | Loss of vascular integrity, increased capillary permeability, increased interstitial volume, diminution of blood volume |
| What is the rule about fluid loss? | It is proportional to the depth of the burn |
| what is the result of fluid loss? | Hypovolemia, hypotension, tachycardia, decreased CO, vasoconstriction, Kindey ischemia |

| how do you treat a second degree burn? | cool compress, leave blisters intact, cleanse wounds, occulsive dressing |
| what is the purpose of occlusive dressings? | Absorptive, bulky, eliminate dead space, give vascular support, splinting effect |
| How do we treat a third degree burn? | remove dead tissue, cleanse the burn area, grafting if bigger 3-4cm |
| Skin grafting is priority for what areas? | Face, neck, hands and flexion creases |

| How can you estimate BSA? | anterior surface of palm of the hand= 1% BSA |
| How do we Assess Peripheral Circulation | Capillary refill,cyanosis, doppler |
| What do we look for in the blood work of a burn victim? | CBC, CO levels, electrolytes, ABG, prothrombin, carboxyhemoglobin, pregnancy test in females of childbearing age |
| what other labs would you order? | Chest-Xray not before 48hrs, NG if 25% BSA, Urinary cath X 72hrs, |
| criteria for hospitalization | full thickness (3-4 degree) >2% BSA Partial thickness (2 degree) >10% BSA |
| Criteria for Burn Unit | full thickness >5% BSA Partial thickness >20%BSA or 10% if under 10 or over 50 high voltage electrical burn significant chemical burn inhalation injury |
| What complications should you be aware of for a burn victim? | Infection, gastric distention, paralytic ileus, fecal impaction, curlingulcer, URI obstruction. |
