Circulatory disturbances and changes in body temperature during anesthesia in brain surgery

To assess the adequacy of anesthetic protection during surgical interventions on the brain and in the postoperative period, it is necessary to monitor the central hemodynamics and body temperature regime. Therefore, we performed such control in 52 patients aged from 17 to 60 years old during the operative interventions on the brain under the conditions of intravenous balanced anesthesia with the use of sodium oxybutyrate or nitrous oxide and during 14-16 days in the postoperative period. All patients underwent bone-plastic craniotomy with opening of the dura mater. In 32 patients a brain tumor was removed, in 20 patients a subdural hematoma and cerebral detritus were removed.
