Paralytics

A. Pupils are spared

Large pupils in a pt given paralytics are usually evidence of anxiety from inadequate sedation.

B. Succinylcholine

A depolarizing blocker that can cause autonomic stimulation and raise intracranial pressure. Blunt this by pretreating with pancuronium (nondepolarizing) 1 mg IV, 5 min before succinylcholine.

0.07-0.1 mg/kg IV bolus (typically 8-10 mg/70 kg), 2-3 min onset, lasts 15-30 min. Nondepolarizing.
