A 28-year old female schizophrenic patient underwent electroconvulsive therapy (ECT) under propofol anesthesia. She received ECT five times, and Bispectral Index (BIS) was recorded four times out of the five ECT. BIS values (mean +/- SD) were 95.3 +/- 1.3 before anesthesia, 38.0 +/- 13.1 after loss of consciousness, 45.3 +/- 12.7 immediately after ECT and 27.3 +/- 11.6 about two minutes after ECT. In conclusion, ECT may decrease BIS during continuous propofol infusion.

We investigated the effects of combined inhalational and lumbar epidural anesthesia on body temperature in 8 women for long-lasting lower abdominal surgery. Probes for forehead deep temperature and skin-surface temperatures were placed on the forehead, forearm, fingertip and toe tip on patients' arrival at the operating room. Tympanic membrane temperature was also measured. ⋯ In conclusion, anesthetics-induced redistribution of body heat significantly affects the core temperature throughout anesthesia. Peripheral hypothermia results in core temperature drop when the redistribution is induced by anesthetics. Thermoregulatory vasoconstriction may not only suppress heat loss but also increase core temperature through centralization of body heat.
