Brief Summary

Gastrointestinal dysfunction is common in patients after major surgery, especially for neurosurgery. It was reported 80% of neurosurgery patients could be combined with gastrointestinal dysfunction, and it may relate to old age, surgery time, and factors of anesthesia and surgery. Meanwhile, postoperative constipation, nausea, and vomiting induced by gastrointestinal dysfunction may increase the intracranial bleeding. Oliceridine could activate mu opioid receptors without the interaction of (beta)arr2-muOR, and may reduce the gastrointestinal dysfunction, but a limited study has illustrated this topic. Thus, this study is conducted to explore whether oliceridine could reduce the gastrointestinal dysfunction vs. sufentanil in patients undergoing neurosurgery.

Conditions

Outcome Measures

Primary Outcomes (1)

  • High risk rate of gastrointestinal dysfunction

    The high-risk rate of postoperative gastrointestinal dysfunction was assessed using the Intake, feeling nauseated, emesis, physical examination, and duration of symptoms (I-FEED) scoring system.

    Within 72 hours after the operation

Study Arms (2)

Oliceridine group

EXPERIMENTAL
Drug: Experimental: Oliceridine group

Classical opioid group

ACTIVE COMPARATOR
Drug: Active Comparator: Classical opioid group

Interventions

During the operation, both the induction and maintenance of anesthesia as well as the analgesic drugs were administered with oxilazide. The dosage and administration timing of the drugs were determined by the anesthesiologist.

Oliceridine group

During the operation, both the induction and maintenance of anesthesia were achieved using sufentanil. The dosage and administration timing of the drugs were determined by the anesthesiologist.

Classical opioid group
