Abstract Purpose To investigate the efficacy and safety of low-dose bolus plus continuous infusion of penehyclidine in preventing postoperative nausea and vomiting (PONV) following bimaxillary surgery. Methods Three hundred fifty-four patients were randomly allocated into three groups. In the Control group, placebo (normal saline) was injected before anesthesia and infused over 48 h after surgery; in the Bolus group, 0.5 mg penehyclidine was injected before anesthesia, whereas placebo was infused after surgery; in the Infusion group, 0.25 mg penehyclidine were injected before anesthesia, another 0.25 mg penehyclidine was infused after surgery. The primary endpoint was the incidence of PONV within 72 h. Results A total of 353 patients were included in intention-to-treat analysis. The PONV incidence was 61.0% (72/118) in the Control group, 40.2% (47/117) in the Bolus group, and 28.0% (33/118) in the Infusion group. The incidence was significantly lower in the Bolus group than in the Control group (RR 0.66; 95% CI 0.51–0.86; adjusted P = 0.003) and in the Infusion group than in the Control group (RR 0.46; 95% CI 0.33–0.63; adjusted P < 0.001); the difference between the Infusion and Bolus groups was not statistically significant (RR 0.70; 95% CI 0.48–1.00; adjusted P = 0.144). Emergence agitation occurred more frequently in the Bolus group than in the Control group (36.8% [43/117] vs. 21.2% [25/118], adjusted P = 0.027), but did not differ significantly between the Infusion and Control groups. Conclusions A low-dose bolus plus continuous infusion of penehyclidine was effective in preventing PONV without increasing emergence agitation. Trial registration Clinicaltrials.gov.

Abstract Background: Postoperative nausea and vomiting (PONV) is the most common and undesirable complications associated with anaesthesia, leading to discomfort in patients and extended hospital stays. The present study evaluates and compares the effects of preoperative low-dose mannitol infusion on PONV in patients undergoing gynaecological laparoscopic surgery.Methods: Fifty-three patients were randomly allocated into 2 groups (mannitol group, Group M, and control group, Group C). In the group M, low dose of 20% mannitol (0.5g/kg) was applied 30 minutes before induction. In the group C, equal volume of 0.9% normal saline was infused. Both groups were maintained with Ringer’s lactate in 8 ml/kg/h intraoperatively. The primary endpoint was the incidence and severity of PONV within the first postoperative 24h. The secondary endpoints were the average vascular resistance indexes(RI) and angle-corrected time-averaged flow velocity(TIMV)of bilateral vertebral artery (VA) and internal carotid artery (ICA) and cerebral blood flow volume (CBFV) using non-invasive Doppler ultrasound at time points just 5 min after laryngeal mask airway placement (T1：baseline);pneumoperitoneum started and position changed(T2);15 minutes after pneumoperitoneum with the position change (T3); pneumoperitoneum stopped with a position change (T4);15 minutes after pneumoperitoneum had stopped (T5).Results: Within 24h after operation, the incidence of PONV in group M (28.0%) was significantly lower than group C (56.0%) (P=0.045). Compared with group C, the severity of PONV in group M was significantly lower(P=0.040). The RI of VA and ICA were statistically different between the two groups(P<0.05).No significant differences were observed in the VM of VA and ICA and CBFV between the two groups(P＞0.05).Conclusion: Pretreatment with a low dose of mannitol effectively reduced the incidence and severity of PONV in patients undergoing laparoscopic gynecological surgery by reducing the RI of the VA and ICA.Trial registration: Chinese Clinical Trial Registry (ChiCTR-IPR-16007749, registered date: 12/01/2016.), http://www.chictr.org.cn

Background. Postoperative nausea and vomiting (PONV) is one of common complications in patients undergoing laparoscopic cholecystectomy (LC). Aim of this study was to compare the efficacy of subhypnotic (1 mg/kg/h) infusion of propofol with dexamethasone on PONV in patients undergoing LC.Methods. A total of 120 patients were included in this randomized, double-blind, placebo-controlled study. Patients were randomly assigned to 3 groups; patients of group dexamethasone (group D) were administrated 8 mg dexamethasone before induction of anesthesia, patients of group propofol (group P) were infused to subhypnotic (1 mg/kg/h) propofol during operation and patients of group control (group C) were applied infusion of 10% intralipid. The incidence of PONV and needs for rescue analgesic and antiemetic were recorded in the first 24 h postoperatively.Results. In the 0–24 h, the incidence of PONV was significantly lower in the group D and group P compared with the group C (37.5%, 40%, and 72.5%, resp.). There was no significant difference in the incidence of PONV and use of antiemetics and analgesic between group D and group P.Conclusion. We concluded that infusion of propofol 1 mg/kg/h is as effective as dexamethasone for the prevention of PONV during the first 24 hours after anesthesia in patients undergoing LC.

Abstract Background: Few studies have investigated the effect of dexmedetomidine on postoperative nausea and vomiting (PONV) in patients underwent gynecological laparoscopic surgery. We investigated if adding dexmedetomidine to a morphine-based patient-controlled analgesia (PCA) could decrease the incidence of PONV in this high-risk patient population. Methods: In this prospective, randomized, double-blind and placebo-controlled study, 122 patients underwent gynecological laparoscopic surgery were assigned into two groups. Patients in the dexmedetomidine group (Group Dex) received a loading dose of dexmedetomidine 0.4μg/kg before the end of surgery, followed by morphine 0.5mg/ml plus dexmedetomidine 1μg/ml for postoperative i.v. PCA. Patients in the control group (Group Ctrl) received normal saline before the end of surgery, followed by morphine 0.5mg/ml alone for postoperative i.v. PCA. PCA pump was programmed as followed: bolus dose 2ml, lockout interval 8 minutes and background infusion at a rate of 1ml/h. The primary outcome was the incidence of nausea and vomiting within the first postoperative 24 hours. Results: Although there were no significant differences in regard to the total incidence of PONV (41.0% vs 52.5%, P=0.204), PONV score, time to first onset of PONV, or the need for rescue antiemetics within the first postoperative 24 hr between the two groups, the incidence of nausea and total PONV during the first 2h period was significantly lower in the Group Dex than in the Group Ctrl (9.8% vs 24.6%, P=0.031 and 0.031, respectively). More patients in Group Dex were over sedated or had bradycardia during the PACU compared with Group Ctrl (P=0.040 and 0.036, respectively). Conclusion: Adding dexmedetomidine to morphine-based PCA with a loading dose might reduce the incidence of early postoperative nausea but not total PONV within 24h after surgery in patients undergoing gynecological laparoscopic surgery.

Background: We performed this prospective double-blind randomized controlled trial to identify the effect of a preoperative prophylactic transdermal scopolamine (TDS) patch on postoperative nausea and vomiting (PONV) after retromastoid craniectomy with microvascular decompression (RMC-MVD). Methods: We recruited 38 patients undergoing RMC-MVD and randomized them into two groups: the TDS group (n = 19, application of the TDS patch) and placebo group (n = 19, application of a sham patch). Nausea (as a self-reported 100-mm visual analog scale (VAS) score; range, 0 (no nausea) to 10 (worst nausea)), vomiting, and the use of antiemetics were the primary endpoints. Results: There was no significant difference in terms of the incidence of PONV (73.7% in the TDS group and 78.9% in the placebo group; p = 1.00) between the groups. However, the mean nausea VAS score was significantly different at arrival to the general ward (0.93 ± 1.71 in the TDS group vs. 2.52 ± 2.85 in the placebo group; p = 0.046), and throughout the study period (0.03 ± 0.07 in the TDS group vs. 0.44 ± 0.71 in the placebo group; p = 0.029). Rescue antiemetics were more frequently used in the placebo group than in the TDS group (9 (47.4%) vs. 2 (10.5%), respectively; p = 0.029). The mean number of antiemetics used throughout the study period was significantly higher in the placebo group than in the TDS group (1.37 ± 2.19 vs. 0.16 ± 0.50, respectively; p = 0.029). Conclusions: The preoperative prophylactic use of a TDS patch was safe and effective in the management of PONV after RMC-MVD in terms of the severity of PONV and the use of rescue antiemetics.

Abstract Objective To investigate the effects of preoperative fasting abbreviation with a carbohydrate and protein-enriched solution, on postoperative nausea and vomiting (PONV) incidence in gynecological surgery patients, a population naturally at risk for such unpleasant episodes. Methods The present prospective double-blind randomized study was performed at The Hospital Municipal e Maternidade Dr. Odelmo Leão Carneiro (HMMOLC, in the Portuguese acronym), in Uberlândia, state of Minas Gerais, Brazil, in partnership with the Gynecology Department of the Universidade Federal de São Paulo (UNIFESP), approved by the Human Research Ethics Committee of UNIFESP and the board of HMMOLC, and included in the Brazil Platform and in the Brazilian Clinical Trial Registry. After signing the consent form, 80 women, who were submitted to gynecological surgery in the period from January to June 2016, were randomized into 2 groups: control group (n = 42) and juice group (n = 38). They received, respectively, 200 mL of inert solution or liquid enriched with carbohydrate and protein 4 hours presurgery. The incidence, frequency and intensity of PONV were studied using the Visual Analogue Scale (VAS), with statistical analysis performed by the software IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp, Armonk, NY, USA). Results The incidence of nausea and vomiting was lower than in the literature, to this population, with 18.9% (14/74) for the control group and 10.8% (8/74) for the juice group, respectively, with no statistically significant difference between the groups. Conclusion The incidence of nausea and vomiting was lower than in the literature, but it cannot be said that this is due to the abbreviation of fasting. It can provide greater comfort, with the possibility of PONV prevention in patients at risk for these episodes.
