What is a second degree burn?
These are the primary concerns during anesthesia for debridement and grafting procedures in burn patients.
What is significant blood loss and heat loss.
In the Parkland formula for fluid resuscitation in adults, __________ of the calculated fluid volume is administered during the first 8 hours, with the remaining __________ given over the subsequent 16 hours.

B. Singed nasal or facial hair
C. Presence of carbonaceous material in the airway
D. Both B and C
D. Both B and C
slide 10
Awake oral or nasal intubation is recommended for patients with upper airway burns to prevent obstruction and asphyxia.
True
slide 11
This organ system is prone to failure due to hypoperfusion and rhabdomyolysis in severe burns.
What is the renal system?
This is the recommended approach for intubating patients with extensive facial burns.
What is awake fiberoptic bronchoscopy?
What are two indicators of an inhalational burn injury that would increase the urgency for immediate airway intervention?
Singed nasal or facial hair; carbonaceous material in the airway.
slide 10
Which hemodynamic change occurs within the first 24-48 hours after a major burn injury?
A. Increased cardiac output and blood pressure
B. Decreased cardiac output and increased systemic vascular resistance (SVR)
C. Decreased systemic vascular resistance (SVR) and hypotension
D. Increased oxygen consumption and glucose tolerance
B. Decreased cardiac output and increased systemic vascular resistance (SVR)
slide 16
Ketamine is avoided during debridement procedures in burn patients due to its risk of hemodynamic instability.
False: Ketamine is preferred for its hemodynamic stability and profound analgesia.
slide 23
This immune complication is commonly caused by Staphylococcus aureus or Pseudomonas aeruginosa in burn patients.
What is sepsis?
What are the 3 major things to remember in the resuscitative phase of burn injury?
What is patients are vasoconstricted, hyper coagulable, and hemoconcentrated.
True/False:
Hypovolemia in the first 24-48 hours post-burn is associated with decreased cardiac output and increased systemic vascular resistance (SVR).
True.
slide 16
Why should succinylcholine be avoided 24 hours to 2 years post-burn injury?
A. It causes severe bradycardia in burn patients.
B. It increases the risk of hyperkalemia due to upregulated nicotinic receptors.
C. It has no effect on burn patients.
D. It decreases drug metabolism and clearance.
B. It increases the risk of hyperkalemia due to upregulated nicotinic receptors.
slide 25
Adequate fluid resuscitation in burn patients is determined by achieving a urine output of 0.5–1.0 mL/kg/hr.
True
slide 22
This muscle relaxant should be avoided 24 hours to 2 years post-burn due to hyperkalemia risk.
What is succinylcholine?
What hemodynamic changes would you expect immediately post burn?
What is CO and arterial BP decreased (24-48hrs) and SVR and PVR are increased d/t hypovolemia.
The two most common toxic substances responsible for airway injury during smoke inhalation are __________ and __________.
What are Carbon monoxide; cyanide.
slide 12
Which of the following is the most common cause of inhalation injury-related deaths in burn patients?
A. Cyanide toxicity
B. Carbon monoxide poisoning
C. Superheated air inhalation
D. Nitrogen dioxide exposure
B. Carbon monoxide poisoning
slide 12
Inhalation injury involving carbon monoxide requires administration of 50% oxygen to decrease its half-life six-fold.
False: correct intervention is administration of 100% oxygen.
slide 12
Burn patients may require 2-3 times the ED95 dose of these agents.
What are non-depolarizing muscle relaxants?
Which type of IV fluid should be used for resuscitation in burn patients, and when should it start?
What is Lactated ringers and as soon as possible?
Explain why non-depolarizing muscle relaxants may require higher doses in burn patients and name one commonly avoided agent.
what is burn patients exhibit an anti-curare effect due to upregulation of post-junctional nicotinic receptors, requiring 2–3 times the ED95 dose of non-depolarizing muscle relaxants.
