Effects of Penehyclidine in Preventing Postoperative Nausea and Vomiting in Patients Underging Bimaxillary Surgery: A Randomised Controlled Trial
In Brief
A clinical study evaluating Single injection of penehyclidine, Continuous infusion of penehyclidine, and 1 other intervention for Penehyclidine and 2 related conditions. Completed, enrolled 354 participants across 1 site.
Detailed 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.

Interventions
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.
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.
