Postoperative nausea and vomiting (PONV) after vitreoretinal surgery may potentially be associated with severe complications, such as suprachoroidal hemorrhage. The purpose of the present multicenter clinical trial (NCT02386059) was to assess the efficacy of three different prophylactic treatments for PONV after vitrectomy under local anesthesia. Patients undergoing primary vitrectomy were randomized to the control arm or to one of the treatment arms (4 mg ondansetron, 4 mg dexamethasone, combination of the two drugs). The primary outcome measure was the proportion of complete response (no nausea, no vomiting, no retching, and no use of antiemetic rescue medication) during 24 h after vitrectomy. Secondary outcomes included the severity standardized score of PONV, postoperative pain standardized score, and rate of ocular and non-ocular adverse events. Baseline demographics of the 1287 patients were comparable between the four arms. The combined therapy group showed a statistically significant lower incidence of PONV compared to the placebo and monotherapy (p < 0.001). PONV severity was also reduced in the combination group compared to the others (p < 0.001). Postoperative pain scores and adverse events were comparable among the four groups. Combined therapy with dexamethasone and ondansetron was the most effective treatment for reducing the incidence and severity of PONV in patients undergoing vitrectomy under local anesthesia.

Significant Difference

Background: Two major complications of surgeries are postoperative nausea and vomiting (PONV) and also postoperative pain (POP). Several studies have compared total intravenous anesthesia (TIVA) with inhalational anesthesia regarding these two complications. Some results have shown a better postoperative recovery conditions, but other contradictory results can also be found. This study was performed to evaluate and compare the effect of inhalational and intravenous anesthesia in patients undergoing elective laparoscopic surgery, on the incidence and the severity of PONV and POP. Methods: This study was performed as a single-blinded prospective clinical trial. All patients aged 18-65, with ASA class I and II who underwent elective laparoscopy were included. Patients were divided into two groups of intravenous anesthesia and inhalational anesthesia. The incidence and the severity of PONV and POP were examined in 5 separated times after the surgery. The use of a rescue antiemetic and analgesic medication were also evaluated. Results: Overall, 67 patients received inhalational anesthesia and 55 patients received intravenous anesthesia. It was revealed that 47.8% of the patients in the inhalation group and 18.2% of the patients in the intravenous group developed PONV (P<0.001). The severity of PONV was significantly lower in the TIVA group (P<0.001), however, no statistically significant difference was found regarding the severity of abdominal pain (P=0.62). Conclusion: The incidence of PONV and the need for administration of an antiemetic rescue drug are significantly lower in the TIVA group.

Purpose: To date, no protocol of anesthesia for pediatric ophthalmic surgery is unanimously recognized. The primary anesthetic risks are associated with strabismus surgery, including oculocardiac reflex, postoperative nausea and vomiting, and postoperative pain. Methods: This was a prospective, monocentric, observational study conducted in a tertiary pediatric ophthalmic unit. Our anesthetic protocol for strabismus surgery included postoperative nausea and vomiting prevention using dexamethasone and ondansetron. No drug-based prevention of oculocardiac reflex or local/locoregional anesthesia was employed. Results: A total of 106 pediatric ophthalmic surgeries completed between November 2015 and May 2016 were analyzed. The mean patient age was 4.4 (range: 0.2–7.3, standard deviation: 2.4) years. Ambulatory rate was 90%. Oculocardiac reflex incidence was 65% during strabismus surgery (34/52), 50% during congenital cataract surgery (4/8), 33% during intramuscular injection of botulinum toxin (1/3), and 0% during other procedures. No asystole occurred. Postoperative nausea and vomiting incidence was 9.6% after strabismus surgery (5/52) and 0% following the other procedures. One child was hospitalized for one night because of persistent postoperative nausea and vomiting. Postoperative pain generally occurred early on in the recovery room and was quickly controlled. Its incidence was higher in patients who underwent strabismus surgery (27%) than in those who underwent other procedures (9%). Conclusion: Morbidity associated with ophthalmic pediatric surgery is low and predominantly associated with strabismus surgery. The benefit–risk ratio and cost-effectiveness of oculocardiac reflex prevention should be questioned. Our postoperative nausea and vomiting rate is low, thanks to the use of a well-managed multimodal strategy. Early postoperative pain is usually well-treated but could probably be more effectively prevented.

This case focuses on the prevention of postoperative nausea and vomiting (PONV) by asking the question: What is the efficacy of six well-established prophylactic antiemetic strategies individually and in combination for the prevention of postoperative nausea and vomiting? Each of the three antiemetics in this study (ondansetron, dexamethasone, and droperidol) reduced the risk for PONV by approximately 26%; substituting propofol for volatile anesthetic reduced the risk by 19%; and substituting nitrogen (air) for nitrous oxide reduced the risk by 12%. A maximum reduction of 70% in the relative risk for PONV can be expected when total intravenous anesthesia is used with three antiemetics. The appropriate approach to the management of PONV depends on the patient’s baseline risk factors as well as the likelihood of adverse events and costs from the antiemetic medications.

Background This study was designed to evaluate transcutaneous electrical acupoint stimulation (acustimulation) using the ReliefBand compared with ondansetron for the treatment of established postoperative nausea and vomiting (PONV) after outpatient laparoscopic surgery. Methods After the authors obtained institutional review board approval and written informed consent, 268 outpatients were enrolled in this randomized, double-blind, placebo- and sham-controlled study. All patients received antiemetic prophylaxis with metoclopramide, 10 mg intravenously, or droperidol, 0.625 mg intravenously, after induction of anesthesia. A total of 90 patients developed PONV in the recovery units and were randomized to one of three treatment groups: (1) the ondansetron group received 4 mg intravenous ondansetron and a sham ReliefBand; (2) the acustimulation group received 2 ml intravenous saline and a ReliefBand; and (3) the combination group received 4 mg intravenous ondansetron and a ReliefBand. A rescue antiemetic (10 mg intravenous metoclopramide) was administered only if the PONV symptoms persisted for 15 min or longer after initiating the treatment. A blinded observer recorded the recovery times, emetic symptoms, rescue antiemetics, maximum nausea scores, complete response to study treatment, and time to achieve discharge criteria. Postdischarge side effects, as well as patient satisfaction and quality of recovery scores, were assessed at 24 and 72 h after surgery. Results The combination group had a significantly higher complete response rate than the acustimulation group (73% vs.40%, P &lt;0.01). In addition, fewer patients (8 vs. 18) in the combination (vs. acustimulation) group experienced subsequent emetic events (P &lt; 0.03). However, there were no significant differences between the three groups with respect to patient satisfaction and quality of recovery scores. Conclusions Acustimulation with the ReliefBand can be used as an alternative to ondansetron for the treatment of established PONV. However, the use of ondansetron (4 mg intravenously) in combination with the ReliefBand device improved the complete response rate to the acustimulation therapy.

Abstract Background: Postoperative nausea and vomiting (PONV) are common side-effects following strabismus surgery. The present study aimed to compare the effects of different doses of dexmedetomidine (DEX) on PONV incidence in pediatric patients undergoing strabismus surgery. Methods: In this prospective randomized double-blinded study, 126 pediatric patients undergoing strabismus surgery were randomized into one of three groups: Placebo group, normal saline; DEX1 group, 0.3 ug/kg dexmedetomidine, and DEX2 group, 0.5 ug/kg dexmedetomidine. Oculocardiac reflex (OCR) events were recorded during surgery. PONV or postoperative vomiting (POV) was recorded for 24 hours in the ward. Pediatric anesthesia emergence delirium (PAED) scale and emergence agitation (EA) scale were recorded in the recovery room. Results: Intraoperative OCR was significantly reduced in DEX2 group (42%) as compared to that of Placebo group (68%) (p=0.0146). During the first 24 hours post-op, the overall incidence of PONV was significantly lower in DEX2 group (10%) than that of Placebo group (32%) (p=0.0142). There was no significant difference in POV among the three groups. PAED or EA scores among the three groups were similar during recovery time. Conclusion: Dexmedetomidine (0.5 ug/kg) reduced OCR and PONV without lengthening extubation time or recovery time in pediatric patients undergoing strabismus surgery. Trial registration：The trial was prospectively registered before patient enrollment at Chinese Clinical Trial Registry (Clinical Trial Number: ChiCTR1800020176, Date: 12/19/2018).
