Case ReportsEnflurane-induced grand mal seizures during otic microsurgery.
Abnormal electroencephalographic seizure-like activity and myoclonic movements have been recognized during enflurane anesthesia. This is most commonly seen in the presence of respiratory alkalosis and high concentrations of enflurane. ⋯ Experimental studies have shown that auditory stimuli could facilitate seizure activity during deep enflurane anesthesia. Here we report a case of intraoperative generalized tonic-clonic convulsion during low concentrations of enflurane without evidence of hyperventilation and the presence of auditory stimulation.
