Low dose sufentanil for major intracranial surgery

The use of intravenous sufentanil in a single dose of 3 to 5 micrograms/kg body weight, was evaluated in 41 patients anesthetised for major intracranial surgery. It was assessed in a technique of balanced anesthesia which allowed controllable alteration in cardiovascular parameters and rapid postoperative recovery and neurological evaluation. It was concluded that the 4 micrograms/kg dose was superior regarding peroperative stability and recovery. The delayed recovery in aneurysm and fossa posterior surgery should be explained by several factors not involving the anesthetic technique.
