Week 3 Thermal Injury Flashcards
Classify the different types of burns?
-1 DEGREE
>Limited to epidermis and heals spontaneously
- 2 DEGREE
>Extends to dermis and may need grafting
(deep, superficial partial thikness) - 3 DEGREE
>Extend to subcutaneous and skin grafting is
required. (full thickness) - 4 DEGREE
>Muscle, fascia, bone which is extensive
Major burns are specified by:
- 2nd degree >10% for adults and >20% extremes of age
- 3rd degree > 10%
- Electical Burns
- One complicated with inhalation
Are all electrical burns considered major?
YES
How do you calculate mortality of burn patients?
Age + TBSA % = ( >115 and mortality is >80%)
T/F: Mortality is doubled with inhalation burn patients.
TRUE
What is important to remember about a chemical burn?
- continues until removed or neutralized
- initial treatment with copious amounts of fluid
Electric burns will cause what problems?
- myoglobinia
- renal failure
What is the most common type of burn injury in children?
- Thermal
What inhalation burns will be seen in the upper airway?
- Thermal air
- Steam
- Smoke
- Chemicals from TOXINS
What inhalation burns will be seen in the lower airway?
- Chemical
- Soot partical
During the resuscitative phase what type of intubation would be typically done?
- Direct laryngoscopy
- Fiberoptic
- Awake
During the resuscitative phase succinylcholine is given. What electrolyte would be increased and proliferation of what receptor?
- K+
- Acetylcholine
T/F: After 24 hours it is not safe to administer succinylcholine.
TRUE
When is it safe to give a burn patient succinylcholine.
- Wound is healed
- Patient gaining weight
Burn patient may need an increase in NDNMB by how much?
- 2 to 3 fold
How many burn patient die from CO poisoning?
50-60%
CO bind to hemoglobin by __ time the affinity than O2.
-200
What does CO cause to the tissue of the body?
-Disrupts oxidative phosphorylation
Metabolic acidosis at cellular level
The value for SaO2 to a patient with CO poisoning is?
Normal
The value for a SaO2 to a patient with CO poisoning?
Decreased Total Oxygen
A Co-Oximetry will give what information:
-True value of SaO2 and CO
When is fluid shift the greatest in a burn patient?
1st 12 hours
When will the patient begin to stabilize?
24 hours
When does the hypermetabolic/hyperhemodynamic phase begin?
48 hours
