Background and Aims Psychogenic nonepileptic seizures are unusual events that may occur in the perioperative period. It can mimic other complications causing confusions and misdiagnosis to regional anesthesiologist
Methods Case of a 24 yo female for Open Reduction Internal Fixation of Ankle for Closed Distal Fibular Fracture Right. General Anesthesia with Ankle Block was done after consent. Intraoperatively, after induction and regional block performed, patient was stable all throughout the procedure. Surgery lasted for 3 hours. Patient was transported to the recovery room, uneventful.
Results 30 minutes postoperatively, patient developed signs of irregular uncontrolled movements, upward rolling of the eyes with no verbal response. Shivering and Seizure after local anesthetic toxicity were immediately considered with benzodiazepine and Lipid Emulsion initiated. Repeated attacks were recorded until 72 hours post operatively with an interval in between of intact sensorium and orientation. Attacks were noted to be triggered by severe pain. The longest duration noted to be was 25 minutes. However resistance to anticonvulsants, benzodiazepines were eventually noted. A 12 hour video Electroencephalogram was done with 2 attacks captured during the procedure and revealed a normal result. A psychogenic nonepileptic seizure was then considered until discharged.
Conclusions Psychogenic nonepileptic seizures are rare with 1.4 per 100 000 and an estimated prevalence of 2-3 per 10000. Knowledge and correct diagnosis is of tantamount importance to anesthesiologists to prevent morbidity and mortality brought about by anticonvulsive therapy such as respiratory depression, risk and injury brought by tracheal intubation, with prolonged hospital stay and added costs especially in this third world country.
