Can Propofol Lead to an Increase in Seizure Threshold Over the Course of Electroconvulsive Therapy?

ABSTRACT

OBJECTIVE: To evaluate the effects of 2 different dose regimens of propofol (low dose 25 sn) during the course of ECT in higher propofol doses. Although there was an increase in the seizure threshold over the course of ECT in both groups, this increase was found to be much more pronounced in the high-dose propofol group according to the low-dose propofol group. Longer duration of seizures was observed in the low-dose propofol group. CONCLUSION: Higher doses of propofol in induction of anesthesia can lead to a more progressive rise in seizure threshold than lower doses of propofol.
