Abstract

Abstract : Objectives: Super refractory status epilepticus (SRSE) is a stage beyond refractory status that requires general anesthesia as management. Electroconvulsive therapy (ECT) is recommended only as a potential treatment option beyond general anesthesia and after all other options have been exhausted. Its effect on aborting status has been minimally researched. We present the largest case series to our knowledge exploring the effect of ECT on SRSE. Methods: Eight adults hospitalized for SRSE received ECT in an attempt to abort status after other treatment modalities were exhausted. Electroconvulsive therapy consisted of a 504-mC (≈99.4 J) stimulus delivered bifrontotemporally with a constant 0.5-millisecond pulse width. Seizure activity during ECT was monitored visually and correlated to the single-channel recording provided by the apparatus. Results: There was neurotelemetry or clinical evidence of improvement within 24 hours after the full course of ECT treatment in 5 (63%) of the 8 cases. Cases that improved were given an average of 7.8 total ECT stimulations, eliciting an average of 4.2 total seizures. Conclusions: Although it is difficult to determine the exact role of ECT in the improvement of 63% of our cases, we present a series of patients for whom pharmacotherapy, ketogenic diet, and general anesthesia otherwise did not produce an appreciable effect on status prior to implementation of ECT. These findings suggest that cases of SRSE may benefit from ECT administration.
