Hypothermia and intracranial aneurysm surgery:part 1 "IHAST1"


Phase N/A Results


Seven patients in the hypothermic group, three of whom were obese, could not be cooled to within 1 degree C of the target temperature. Although there were no statistically significant benefits from intraoperative hypothermia in the group with acute subarachnoid hemorrhage (n = 52), there were trends toward a lower frequency of postoperative neurological deterioration, of discharge to home, and of long-term good results. The group without acute subarachnoid hemorrhage (n = 62) showed no such benefits. In neither group did intraoperative hypothermia increase morbidity or mortality.
