icuRNmaggie, BSN, RN 1,970 Posts Specializes in MICU, SICU, CICU. Has 24 years experience. Aug 7, 2014 I once had a pt stop breathing in PACU. Awake and paralyzed. Apparently there was a trace of succinylcholine in the manifold that I unknowingly pushed in by giving an IV narcotic. Pt had to be bagged for a few minutes but he did just fine.The moral of the story is - get rid of the anesthesia manifold. Disconnect and flush your lines.
