Burns
Considerations
-
Trauma patient, ATLS approach
-
Difficult/threatened airway: edema, secretions, bleeding
-
Potential inhalational injury & carbon monoxide/cyanide poisoning
-
Hypovolemia & need for goal-directed volume resuscitation (e.g., Parkland, see below)
-
Multisystem dysfunction:
-
Acute:
-
Hypovolemic/cardiogenic shock/low cardiac output state → septic shock/high cardiac output state
-
Pulmonary edema/aspiration/restrictive lung
-
Hyperkalemia/myoglobinuria/AKI
-
DIC, anemia of burns
-
Impaired thermal regulation
-
Difficult monitoring/IV access (ECG patches, BP cuffs, etc)
-
-
Delayed:
-
Sepsis
-
DVT/PE
-
Stress ulcers, adynamic ileus, hypermetabolic/catabolic state
-
-
-
Pharmacologic changes: succinylcholine contraindication (>24 hours to 1year)/NDMR resistance (>60 days)
-
Complications of resuscitation:
-
Abdominal compartment syndrome
-
Fluid creep (pulmonary edema, venous congestion, graft dysfunction)
-
-
Frequent ORs (debridement/grafting):
-
Blood loss
-
Pain, opioid tolerance
-
Possible remote location
-
Goals
-
ATLS approach
-
Secure definitive airway (facial/neck/inhalational or major burn)
-
Assess burn severity/extent
-
Volume resuscitation (formula driven, goal directed)
-
Measure CO levels with co-oximetry
-
Prevent end-organ dysfunction (lung protective strategy if ARDS, urine output >1ml/kg/hr)
-
Adequate analgesia (multimodal approach +/- antidepressants)
Parkland Formula
-
4cc X %BSA X weight (kg)
-
E.g. 70kg patient with 20% burn
-
4cc X 20 X 70 = 5600cc
-
-
-
Total fluid for 24 hrs: 1/2 in first 8 hrs, 1/2 in next 16 hrs
-
Clinical end points:
-
Urine output >0.5cc/kg/hr
-
Follow HR/BP, goal MAP >60
-
Follow lactate/mixed venous
-
