Brief Summary

Optional brain relaxation improves the surgeon's operating conditions and is likely to minimize the degree of retraction injury ,with the potential for providing patients with a better outcome. The choice of anesthetic drugs can affect intraoperative brain relaxation. Propofol suppresses brain metabolism, reduces cerebral blood flow, and provides satisfactory brain relaxation. Desflurane is often criticized in neurosurgery due to its cerebral vasodilation and potential to increase intracranial pressure, however, it has been found to have a little clinical significance. This study intends to compare the effects of desflurane with propofol on brain relaxation in patients with supratentorial tumors under mild hyperventilation, and to provide new clinical evidence for the use of desflurane in neurosurgical anesthesia.

Outcome Measures

Primary Outcomes (1)

  • Proportion of satisfactory brain relaxation

    Assessed by the neurosurgeon using a 4-point scale (1= perfectly relaxed, 2= satisfactorily relaxed, 3= firm brain, 4=bulging brain) at the opening of the dura mater, score 1 and 2 represent satisfactory brain relaxation

    during surgery

Secondary Outcomes (9)

  • Emergence time

    from drug discontinuation to eye opening, assessed up to 1 hours

  • Extubation time

    from drug discontinuation to tracheal extubation, assessed up to 1 hours

  • Postoperative complications

    from drug discontinuation to discharge from PACU (Postanesthesia care unit), assessed up to 3 hours

  • Postoperative pain and postoperative nausea and vomiting (PONV)

    during the PACU stay and postoperative day 1.

  • Duration in PACU (Postanesthesia care unit)

    from entering PACU to exiting PACU, an expected average of 1 hour

  • +4 more secondary outcomes

Study Arms (2)

Desflurane inhalational anesthesia

EXPERIMENTAL
Drug: Desflurane

Propofol total intravenous anesthesia

ACTIVE COMPARATOR
Drug: Propofol

Interventions

After induction, anesthesia will be maintained with 0.8-1.3 MAC desflurane and 0.05-0.2 μg/kg/min remifentanil.
