Penehyclidine for prevention of postoperative nausea and vomiting following bimaxillary orthognathic surgery: a randomized, double-blind, controlled trial

Postoperative nausea and vomiting in orthognathic surgery: systematic review and meta-analysis

PURPOSE

Postoperative nausea and vomiting (PONV) is a frequently reported adverse event following orthognathic surgery. The aim of this work is to conduct a systematic review of the literature on the subject, and to discuss the role of maxillofacial surgeons and the steps that can be taken to prevent or control PONV in orthognathic surgery.

METHODS

A systematic review was conducted according to the PRISMA guidelines, using the search strategy: (orthognathic AND (nausea OR vomiting)). The authors searched PubMed, Embase, Dimensions, Web of Science and Google Scholar databases, without any language restrictions. RevMan 5.4 was used to create a risk of bias graph and a forest plot.

RESULTS

The included articles were classified as having a low risk of bias, despite the limited literature on the subject. Various measures have been reported to be beneficial in preventing or managing PONV, such as the use of dexamethasone, antiemetic drugs, gastric aspiration, and anesthetic blocks. Effective bleeding control and faster surgeries can also be helpful.

CONCLUSIONS

Throat packs have not been found to be effective in preventing PONV. Although no definitive protocol has been established in the literature, the Enhanced Recovery After Surgery (ERAS) protocol could be a useful approach. Overall, a multimodal approach may be taken to prevent PONV, and further research is needed to establish definitive protocols.

Penehyclidine for Prevention of Postoperative Nausea and Vomiting in Patients Undergoing Gynecological Laparoscopic Surgery Under Combined Intravenous and Inhalation Anesthesia: A Randomized, Double-Blind, Placebo-Controlled Trial

Purpose

We designed this study to investigate the effect of intravenous use of penehyclidine on postoperative nausea and vomiting (PONV) after gynecological laparoscopic surgery.

Patients and Methods

Ninety-two Women Patients (Aged ≥ 18) Scheduled for Elective Gynecologic Laparoscopy Were Enrolled in the Current Study. Patients Were Equally Randomized Assigned Into Penehyclidine group (PHC group: received a bolus of penehyclidine 10 μg/kg during the induction of anesthesia, then followed by a continuous infusion of 10 μg/kg penehyclidine at a fixed rate of 2.0 mL/h in postoperative intravenous analgesia pump over 48h, 0.5 mg upper limit respectively) or Control group (received 0.9% saline in replace of penehyclidine at the same time points). The primary outcome measure was the incidence of postoperative nausea and vomiting in the postanesthesia care unit and ward area. Quality of Recovery-15 (QoR-15) scores and general comfort questionnaire (GCQ) scores were assessed on postoperative day (POD) 1, 2.

Results

Patients between two groups had comparable baseline characteristics. Compared with the Control group, the incidence and severity of PONV, postoperative nausea (PON), and postoperative vomiting (POV) were significantly lower in the PHC group at 2h (PONV: P = 0.002, P = 0.004, respectively; PON: P = 0.018, P = 0.038, respectively; POV: P = 0.011, P = 0.072, respectively), 24h (PONV: P = 0.003, P = 0.001, respectively; PON: P = 0.010, P = 0.032, respectively; POV: P = 0.006, P = 0.044, respectively), and 48h (PONV: P = 0.003, P = 0.002, respectively; PON: P = 0.007, P = 0.019, respectively; POV: P = 0.002, P = 0.013, respectively) after surgery. The QoR-15 and GCQ scores of the PHC group were significantly higher than those of the Control group at POD 1, 2 (P < 0.001; P < 0.001, respectively).

Conclusion

Our findings suggest that perioperative intravenous application of penehyclidine can effectively prevent postoperative nausea and vomiting in gynecological laparoscopic surgery patients and improve postoperative recovery.

Optimizing drug regimens and supplementation in orthognathic surgery: A comprehensive and practical guide

OBJECTIVE

This study aimed to comprehensively review the literature and provide a practical guide for optimizing drug regimens and supplementation related to orthognathic surgery.

METHODS

The authors conducted a thorough review of the existing literature, following the PRISMA-ScR guidelines. Various types of studies except case reports and reviews were included. The study applied specific inclusion criteria, focusing on perioperative and/or postoperative drugs, medications, or supplementation related to orthognathic surgery.

RESULTS

This guide included 78 studies on various medications in orthognathic surgery. It encompasses clinical trials, cohort studies, cross-sectional studies, prospective and retrospective studies. The topics covered include antibiotics, analgesics, corticosteroids, antiemetics, hemostatic agents, local anesthetics, herbal medicine, and botulinum toxin. Pain and edema control involved specific medications, while local anesthesia utilized ropivacaine and bupivacaine. The guide also discusses mineral and vitamin supplementation. The effectiveness of hemostatic agents and antiemetics was highlighted.

CONCLUSION

Pain management, reduced swelling, enhanced wound healing, and faster recovery are among the advantages. In addition to the standard drugs and medications, the inclusion of vitamin and mineral supplements, tranexamic acid, postoperative anesthetic blocks, and preemptive antiemetics is anticipated to offer various benefits in orthognathic surgery, despite the limited available evidence.

Penehyclidine hydrochloride for treating postoperative nausea and vomiting after laparoscopic bariatric surgery: a double-blinded randomized controlled trial

BACKGROUND

Postoperative nausea and vomiting (PONV) is a common and distressing complication of laparoscopic bariatric surgery (LBS). Penehyclidine hydrochloride has been reported to be effective in preventing PONV. Considering the potential preventive effects of penehyclidine against PONV, we hypothesized that intravenous infusion of penehyclidine may alleviate PONV within the first 48 h in patients scheduled for LBS.

METHODS

Patients who underwent LBS were randomly assigned (1:2) to receive saline (Control group, n = 113) or a single intravenous dose of penehyclidine 0.5 mg (PHC group, n = 221). The primary outcome was incidence of PONV within the first 48 h postoperatively. Secondary endpoints included severity of PONV, need for rescue antiemetic therapy, volume of water intake, and time to first flatus.

RESULTS

PONV occurred in 159 (48%) patients within the first 48 h postoperatively, including 51% in the Control group and 46% in the PHC group. There was no significant difference in the incidence or severity of PONV between the two groups (P > 0.05). Within the first 24 h and 24-48 h, no significant difference was found in incidence or severity of PONV, postoperative nausea, postoperative vomiting, need for rescue antiemetic therapy, or volume of water intake (P > 0.05). Kaplan-Meier curves showed that penehyclidine was significantly associated with a prolonged time to first flatus (median onset time: 22 h vs. 21 h, P = 0.036).

CONCLUSIONS

Penehyclidine did not decrease incidence and severity of PONV in patients undergoing LBS. However, a single intravenous dose of penehyclidine (0.5 mg) was associated with a slightly prolonged time to first flatus.
