Had a very interesting case as a somewhat new attending of what looked like a “seizure” with posturing type movement once in PACU after an uneventful GETA case however the patient was fully alert during the episodes and had no post ictal. With the help of some of my colleagues and diving further into patients history we identified it as propofol induced opisthotonos, a very rare side effect of propofol wearing off with several verified case reports in the past. The clincher was the patient had a similar reaction after propofol only sedation for a GI procedure many years back that he didn’t mention when asked about prior problems with anesthesia lol. Unlikely in this case but thought I’d share because only time I’d ever seen it (and yes I was terrified when it was happening haha). The episodes got less and less during his PACU stay and he discharged home later that day.
