(p. 852)

6

What should NOT be applied to burns during the initial burn management?

ice, lotions, betadine, hydrogen peroxide

7

What is the fluid of choice for resuscitation of a burn patient?

lactated ringer's; use crystalloids, not colloids

[Dr. Myers' Burn powerpoint/camtasia lecture]

8

What is the Parkland formula?
Calculate the volume for 24-hour resuscitation of a 100 kg man with 50% TBSA burns.

4 cc's per kg, x (TBSA% x 100)

(e. g. a 100 kg man with burns over 50% of his body should receive [4 x 100(kg) x 0.50 x 100] = 20,000 cc's or 20 liters given in the first 24 hours.

(p. 852)

9

After calculating the 24 hour resuscitation volume using the Parkland formula, how much should you give and when?

Give half of the total volume in the first 8 hours (measured from the time of injury, not beginning of medical treatment), then one
quarter of it over the next 8 hours, and the last quarter of it over the last 8 hours.

(Example: 20 L total volume. Give 10 L over the first 8 hours, 5 L over the next 8 hours, and another 5 L over the last 8 hours.)

10

Fluid resuscitation for burn patients should begin __ ___ _____. Fluid requirements are calculated from the ____ __ ______.

in the field
time of injury

(p. 852)

11

bacitracin

16

burns to the face
singed nares or eyebrows
dark soot/mucus from nose or mouth
hoarseness
drooling
difficulty swallowing
hx of a burn that likely occurred in a closed space

17

What are the indications for a timely intubation in a patient with possible laryngeal edema secondary to smoke inhalation injury?
