Summary

Postoperative nausea and vomiting (PONV) is a common complication after surgery. Patients undergoing orthognathic surgery are reported to have a high rate of PONV, especially those undergoing bimaxillary surgery. Activation of cholinergic system plays an important role in the development of PONV. Penehyclidine is an muscarinic antagonists which selectively block M1 and M3 receptors and is commonly used to decrease oral secretion. The investigators hypothesize that continuously administrated penehyclidine during perioperative period can reduce the incidence of PONV in patients undergoing bimaxillary surgery.

Conditions

  • Penehyclidine
  • Postoperative Nausea and Vomiting
  • Bimaxillar Surgery

Interventions

DRUG

Single injection of penehyclidine

A dose of penehyclidine hydrochloride (0.5 mg/5 ml) is injected intravenously before anesthesia induction. A patient-controlled intravenous analgesia pump is provided after surgery, which is established with a mixture of placebo (normal saline 5 ml), sufentanil (1.25-1.5 ug/kg) and tropisetron (10 mg), diluted with normal saline to 100 ml, and programmed to administer a continuous infusion at a rate of 2 ml/h for 48 hours.

DRUG

Continuous infusion of penehyclidine

A dose of penehyclidine hydrochloride (0.25 mg/5 ml) is injected intravenously before anesthesia induction. A patient-controlled intravenous analgesia pump is provided after surgery, which is established with a mixture of penehyclidine hydrochloride (0.25 mg/5 ml), sufentanil (1.25-1.5 ug/kg) and tropisetron (10 mg), diluted with normal saline to 100 ml, and programmed to administer a continuous infusion at a rate of 2 ml/h for 48 hours.

DRUG

Placebo

A dose of placebo (normal saline 5 ml) is injected intravenously before anesthesia induction. A patient-controlled intravenous analgesia pump is provided after surgery, which is established with a mixture of placebo (normal saline 5 ml), sufentanil (1.25-1.5 ug/kg) and tropisetron (10 mg), diluted with normal saline to 100 ml, and programmed to administer a continuous infusion at a rate of 2 ml/h for 48 hours.
