For rapid-sequence induction in a patient with cerebral palsy and severe gastroesophageal reflux, which neuromuscular blocker is preferred at RSI dose?

• A. Succinylcholine
• B. Rocuronium
• C. Vecuronium
• D. Atracurium

Answer: (B)

In rapid-sequence induction, you need an onset of neuromuscular blockade that is fast enough to secure the airway quickly and minimize aspiration risk. In cerebral palsy, using a depolarizing blocker like succinylcholine is risky because chronic neuromuscular conditions can upregulate extrajunctional acetylcholine receptors, causing dangerous hyperkalemia and potential arrhythmias. That makes succinylcholine contraindicated here. A high-dose rocuronium, about 1.0–1.2 mg/kg, provides an onset of roughly 60–90 seconds, approaching the speed of succinylcholine, while avoiding the potassium surge. It offers reliable intubating conditions for RSI and can be reversed with sugammadex if needed, which enhances safety in difficult airway or extended procedures. Other nondepolarizing blockers like vecuronium or atracurium have slower onsets at typical RSI doses, making them less suitable for this scenario.
