The Bispectral Index and induced hypothermia--electrocerebral silence at an unusually high temperature.
The optimal temperature for deep hypothermic circulatory arrest remains undefined. We present a case in which Bispectral Index monitoring during hypothermic cardiopulmonary bypass showed electrocerebral silence at a higher temperature than previously reported. Bispectral Index monitoring may be a potentially useful tool in surgery employing deep hypothermic circulatory arrest.
