Q

what is parkland formula for fluid resus

A

4ml/kg/% BSA
- 1/2 in first 8hrs
- 1/2 in next 16hrs
use ringers lactate

17
Q

3 aspects of DandE in burns

A
  1. all the usual
  2. can also have CO poinsoning
  3. loss of skin> loss of heat> hypothermia
18
Q

3 processes of inhalation injury

A
  1. upper airway injury
  2. subglottic
  3. chemical asphyxia
19
Q

what is issue with CO

A

Hb has stronger affinity for it

  • not picked up on pulse oxymeter
  • no effect of pO2
20
Q

how to treat CO

A

100% O2

- possible hyperbaric O2

21
Q

how is CO diagnosed

A

clinically

  • Hx of exposure
  • Sx of
  • increase COHb in blood
22
Q

Sx of CO

A

HA, confusion, nausea, vomiting, LOC, diszzyness

23
Q

what are abnormal CO Hb levels

A

> 3% in normals

>10% in smokers

24
Q

what is best predictor of outcomes

A

NOT COHb levels

- neurologic outcome
