4 y.o. Trauma Craniotomy
Pediatric neuro-trauma logic involving Cushing's reflex, increased ICP management, and rapid sequence induction in the full-stomach child.
"A 4 y.o. boy is brought to the OR for an urgent craniotomy after a fall. He is lethargic with bradycardia (HR 50) and irregular breaths. CT shows a SDH with midline shift. He ate a sandwich 4 hours ago. PHYS: BP 85/50; HR 50; RR 10; O2 Sat 90%."
Cushing's reflex recognition, increased ICP management, and the risk of succinylcholine in head injury.
Defend your airway management in a child with a full stomach and high ICP while maintaining cerebral perfusion pressure (CPP). Neuro-Peds transitions are common exam pivot points.
How a Board-Certified Consultant answers this scenario.
This child has a classic Cushing's reflex (bradycardia, irregular respirations) indicating dangerously high ICP and impending herniation. My first priority is stabilizing the ICP and securing the airway while assuming a full stomach.
I will manage this with a 'level-headed' Rapid Sequence Induction (RSI): brief pre-oxygenation, cricoid pressure, and titrated induction agents. I'll avoid succinylcholine if possible due to the risk of transient ICP increase, favoring high-dose rocuronium (1.2 mg/kg). I will maintain the CPP by keeping the MAP at a high-normal range for his age and avoiding extreme hyperventilation (Target PaCO2 30-35 mmHg), which can cause cerebral ischemia. I will also administer mannitol or hypertonic saline promptly. The goal is to get him to the OR for decompression as fast as safely possible while preventing secondary brain injury from hypotension or hypoxia.
