Question | Answer |
---|---|
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 |
What are the most common burns in the following age groups? 3-14 15-60 60 | 3-14: flame burns 15-60: industrial accidents 60: Accidents |
What is burn severity dependant on? | Temperature, Duration, Conduction |
What is a first degree burn? | Epidermal involvement ONLY |
What is a second degree burn? | Partial thickness into dermis |
What is a third degree burn? | Dermis though to adipose |
What is a fourth degree burn? | Passes into muscle |
treatment of first degree burns | remove clothing, apply cool compress and soothing lotion |
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 |
what does ABCDE | Airway Breathing Circulation Disability Exposure |
When would you send a patient to a burn unit? | If they had facial burns, singed eyebrows or nasal hairs, confinement in a burning building, impaired mentation, explosion, or CO levels greater than 10% |
how do we evaluate breathing? | 100% O2 and tension pneumothorax, or flail chest |
How do we evaluate circulation? | 16 gauge catheter in a peripheral vein |
How do we evaluate Disability? | AVPU |
How do we replace lost fluid? | 2-4ml IV/kg/%BSA in 24 hrs 1/2 in 8hrs, then second half in 16hrs |

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. |
which is worse: Alkali burn or acid burn? | ALKALI |
How do you irrigate chemical burns | Acid: neutral solution for 20-30 minutes Alkali- irrigate for 8 hrs |
how do you deal with electrical burns? | make sure urine is clear if not increase fluids to 100ml per hour and add 25 gms of mannitol then 12.5 gms to each liter of fluid |
