[Bispectral index monitoring during anesthesia with propofol for electroconvulsive therapy].
We studied the changes in the bispectral index (BIS) of 22 patients during electroconvulsive therapy (ECT) under propofol and succinylcholine anesthesia. BIS values (mean+/-SD) were 94+/-4 before anesthesia, 51+/-15 before ECT, 49+/-20 after ECT, and 60+/-17 at complete re-awakening. The BIS values at re-awakening were significantly different from those before anesthesia (P<0.05). In conclusion, our study suggests that the BIS values following ECT might not reliably correlate with the patients' clinical level of consciousness.
