RESUMO
BACKGROUND: Intrathecal morphine provides effective analgesia for a range of operations. However, widespread implementation into clinical practice is hampered by concerns for potential side-effects. We undertook a systematic review, meta-analysis, and meta-regression with the primary objective of determining whether a threshold dose for non-pulmonary complications could be defined and whether an association could be established between dose and complication rates when intrathecal morphine is administered for perioperative or obstetric analgesia. METHODS: We systematically searched the literature for randomised controlled trials comparing intrathecal morphine vs control in patients undergoing any type of surgery under general or spinal anaesthesia, or women in labour. Primary outcomes were rates of postoperative nausea and vomiting, pruritus, and urinary retention within the first 24 postoperative hours, analysed according to doses (1-100 µg; 101-200 µg; 201-500 µg; >500 µg), type of surgery, and anaesthetic strategy. Trials were excluded if doses were not specified. RESULTS: Our analysis included 168 trials with 9917 patients. The rates of postoperative nausea and vomiting, pruritus, and urinary retention were significantly increased in the intrathecal morphine group, with an odds ratio (95% confidence interval) of 1.52 (1.29-1.79), P<0.0001; 6.11 (5.25-7.10), P<0.0001; and 1.73 (1.17-2.56), P=0.005, respectively. Meta-regression could not establish an association between dose and rates of non-pulmonary complications. There was no subgroup difference according to surgery for any outcome. The quality of evidence was low (Grading of Recommendations Assessment, Development, and Evaluation [GRADE] system). CONCLUSIONS: Intrathecal morphine significantly increased postoperative nausea and vomiting, pruritus, and urinary retention after surgery or labour in a dose-independent manner.

RESUMO
BACKGROUND: Despite recent systematic reviews suggesting their benefit for postoperative nausea, vomiting, or both (PONV) prevention, benzodiazepines have not been incorporated into guidelines for PONV prophylaxis because of concerns about possible adverse effects. We conducted an updated meta-analysis to inform future practice guidelines. METHODS: We included randomised controlled trials (RCTs) of all languages comparing benzodiazepines with non-benzodiazepine comparators in adults undergoing inpatient surgery. Our outcomes were postoperative nausea, vomiting, or both. We assessed risk of bias for RCTs using the Cochrane Risk of Bias tool. We pooled data using a random-effects model and assessed the quality of evidence for each outcome using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS: We screened 31 413 abstracts and 950 full texts. We included 119 RCTs; 104 were included in quantitative synthesis. Based on moderate certainty evidence, we found that perioperative benzodiazepine administration reduced the incidence of PONV (52 studies, n=5086, relative risk [RR]: 0.77, 95% confidence interval [CI] 0.66-0.89; number needed to treat [NNT] 16; moderate certainty), postoperative nausea (55 studies, n=5916, RR: 0.72, 95% CI 0.62-0.83; NNT 21; moderate certainty), and postoperative vomiting (52 studies, n=5909, RR: 0.74, 95% CI 0.60-0.91; NNT 55; moderate certainty). CONCLUSIONS: Moderate quality evidence shows that perioperative benzodiazepine administration decreases the incidence of PONV. The results of this systematic review and meta-analysis will inform future clinical practice guidelines. SYSTEMATIC REVIEW PROTOCOL: The protocol for this systematic review was pre-registered with PROSPERO International Prospective Register of Systematic Reviews (CRD42022361088) and published in BMJ Open (PMID 31831540).

BACKGROUND: Dopamine antagonists, 5-HT3 antagonists, and dexamethasone are frequently used in obstetrics to prevent postoperative nausea and vomiting (PONV). However, the superiority of any drug class is yet to be established. This network meta-analysis aimed to compare the efficacy of these antiemetics for PONV prophylaxis in women receiving neuraxial morphine for Caesarean delivery. METHODS: We searched PubMed, Embase, CENTRAL, Web of Science, and Wanfang Data for eligible randomised controlled trials. Primary outcomes were the incidences of postoperative nausea (PON) and postoperative vomiting (POV) within 24 h after surgery. We used a Bayesian random-effects model and calculated odds ratios with 95% credible intervals for dichotomous data. We performed sensitivity and subgroup analyses for primary outcomes. RESULTS: A total of 33 studies with 4238 women were included. In the primary analyses of all women, 5-HT3 antagonists, dopamine antagonists, dexamethasone, and 5-HT3 antagonists plus dexamethasone significantly reduced PON and POV compared with placebo, and 5-HT3 antagonists plus dexamethasone were more effective than monotherapy. In the subgroup analyses, similar results were seen in women receiving epidural morphine or intrathecal morphine alone but not in women receiving intrathecal morphine with fentanyl or sufentanil. However, most included studies had some concerns or a high risk of bias, and the overall certainty of the evidence was low or very low. CONCLUSIONS: Combined 5-HT3 antagonists plus dexamethasone are more effective than monotherapy in preventing PONV associated with neuraxial morphine after Caesarean delivery. Future studies are needed to determine the role of prophylactic antiemetics in women receiving intrathecal morphine and lipophilic opioids. SYSTEMATIC REVIEW PROTOCOL: PROSPERO CRD42023454602.

BACKGROUND: Intraoperative opioid use has a positive relationship with postoperative nausea and vomiting (PONV), and opioid-free anaesthesia (OFA) might reduce PONV. We investigated whether OFA compared with opioid-based anaesthesia would reduce PONV during the first 2 postoperative days among patients undergoing thoracoscopic lung resection. METHODS: In this randomised controlled trial, 120 adult patients were randomly assigned (1:1, stratified by sex) to receive either OFA with esketamine, dexmedetomidine, and sevoflurane, or opioid-based anaesthesia with sufentanil and sevoflurane. A surgical pleth index (SPI) of 20-50 was applied for intraoperative analgesia provision. All subjects received PONV prophylaxis (dexamethasone and ondansetron) and multimodal analgesia (flurbiprofen axetil, ropivacaine wound infiltration, and patient-controlled sufentanil). The primary outcome was the occurrence of PONV during the first 48 h after surgery. RESULTS: The median age was 53 yr and 66.7% were female. Compared with opioid-based anaesthesia, OFA significantly reduced the incidence of PONV (15% vs 31.7%; odds ratio [OR]=0.38, 95% confidence interval [CI], 0.16-0.91; number needed to treat, 6; P=0.031). Secondary and safety outcomes were comparable between groups, except that OFA led to a lower rate of vomiting (OR=0.23, 95% CI, 0.08-0.77) and a longer length of PACU stay (median difference=15.5 min, 95% CI, 10-20 min). The effects of OFA on PONV did not differ in the prespecified subgroups of sex, smoking status, and PONV risk scores. CONCLUSIONS: In the context of PONV prophylaxis and multimodal analgesia, SPI-guided opioid-free anaesthesia halved the incidence of PONV after thoracoscopic lung resection, although it was associated with a longer stay in the PACU.

BACKGROUND: Intrathecal diamorphine is believed to provide postoperative analgesia but is associated with adverse effects such as nausea and vomiting. There is little evidence of synthesis regarding intrathecal diamorphine in the contemporary literature. We performed a systematic review, meta-analysis with meta-regression and trial sequential analysis to determine the magnitude of intrathecal diamorphine efficacy and safety. METHODS: We systematically searched the literature for trials comparing intrathecal diamorphine with a control group in patients undergoing all types of surgery. The primary efficacy and safety outcomes were intravenous morphine consumption and incidence of postoperative nausea and vomiting at 24 h following surgery, respectively. RESULTS: Twelve trials were identified, which included data for 712 patients. Intrathecal doses of diamorphine ranged from 100 µg to 2500 µg. Intravenous morphine consumption at 24 h postoperatively was significantly reduced in the intrathecal diamorphine group, with a mean difference (95%CI) of -8 mg (-11 to -6), I2 = 93%, p < 0.001. There was a significant difference between three intrathecal diamorphine dosing subgroups but without correlation: mean differences (95%CI) -1 mg (-3-0), -26 mg (-40 to -11) and -6 mg (-15-4) in patients receiving doses of 0-200 µg, 201-400 µg and > 400 µg, respectively (p = 0.003). Intrathecal diamorphine increased postoperative nausea and vomiting with a risk ratio (95%CI) of 1.37 (1.19-1.58), I2 = 7%, p < 0.001. There were no differences in postoperative nausea and vomiting between the three intrathecal diamorphine dosing subgroups. There was no correlation observed with meta-regression of the primary efficacy and safety outcomes. The quality of evidence for all outcomes was very low. CONCLUSION: There is very low level of evidence that intrathecal diamorphine provides effective analgesia after surgery, while increasing postoperative nausea and vomiting with doses > 200 µg.
RESUMO
BACKGROUND: Postoperative nausea and vomiting occur frequently following thyroid and parathyroid surgery and are associated with worse patient outcomes. We hypothesised that opioid-free propofol anaesthesia would reduce the incidence of postoperative nausea and vomiting compared with opioid-inclusive propofol anaesthesia in patients undergoing these procedures. METHODS: We conducted a randomised, double-blinded controlled trial in adult patients scheduled to undergo thyroid and parathyroid surgery at two medical centres in mainland China. Patients were allocated randomly (1:1, stratified by sex and trial site) to an opioid-free anaesthesia group (esketamine, lidocaine, dexmedetomidine and propofol) or an opioid-inclusive group (sufentanil and propofol). Propofol infusions were titrated to bispectral index 45-55. Patients received prophylaxis for nausea and vomiting using dexamethasone and ondansetron and multimodal analgesia with paracetamol and flurbiprofen axetil. The primary outcome was the incidence of postoperative nausea and vomiting in the first 48 h after surgery. RESULTS: We assessed 557 patients for eligibility and 394 completed this trial. The incidence of postoperative nausea and vomiting in the first postoperative 48 h was lower in the opioid-free anaesthesia group (10/197, 5%) compared with opioid-inclusive group (47/197, 24%) (OR (95%CI) 0.17 (0.08-0.35), p < 0.001), yielding a number needed to treat of 5.3. Additionally, opioid-free propofol anaesthesia was associated with a reduced need for rescue anti-emetics, lower rates of hypotension and desaturation after tracheal extubation, and higher patient satisfaction. Time to tracheal extubation was prolonged slightly in the opioid-free group. The two groups had similar postoperative pain scores and 30-day outcomes. DISCUSSION: Opioid-free propofol anaesthesia reduced postoperative nausea and vomiting in patients undergoing thyroid and parathyroid surgery. An opioid-free anaesthetic regimen can optimise anaesthetic care during thyroid and parathyroid surgery.
RESUMO
STUDY OBJECTIVE: This study aimed to explore the relationship between intravenous 5% dextrose infusion during emergence from anesthesia to postoperative nausea and vomiting (PONV) in patients after gynecologic laparoscopic surgery. DESIGN: This was a double-blind randomized controlled trial. Participants were randomized into the experimental group and control group using a computer-generated random number generator. Intervenors and measurers were blinded to group assignments of the study. SETTING: A single academic tertiary medical center. PATIENTS: Patients undergoing gynecologic laparoscopic surgery. INTERVENTIONS: On completion of surgery, participants were randomized into the test group (receive 5% dextrose) and control group (receive Ringer's lactate solution). MEASUREMENTS AND MAIN RESULTS: The primary outcome of the present study was the incidence of PONV. Other outcomes included postoperative rescue analgesic and rescue antiemetic, postoperative pain response, and recovery time of postanesthesia care unit. Baseline characteristics were statistically similar between the 2 groups of participants. There were 49 of 105 patients experienced PONV within 24 hours postoperatively. The overall incidence of PONV within 24 hours postoperatively was not significantly different (45.5% vs 48%; relative risk [RR], 0.95; 95% confidence interval [CI], 0.67-1.37; p = .794). However, fewer patients experienced PONV in the test group than in the control group during 0 to 1 hours (6.0% vs 20.0%; RR, 0.85; 95% CI, 0.73-0.99; p = .024) and 1 to 3 hours (14.5% vs 32.0%; RR, 0.80; 95% CI, 0.64-0.99; p = .033) postoperatively. In addition, recovery time in the postanesthesia care unit was less in the test group (17.07 ± 6.36 vs 22.04 ± 7.33; mean difference, -4.97; 95% CI, -7.62 to -2.32; p <.001) and pain score was lower in the test group during 0 to 0.5 hours postoperatively (2.29 ± 1.74 vs 3.08 ± 1.64; mean difference, -0.79; 95% CI, -1.45 to -0.13; p = .019). CONCLUSION: In patients after gynecologic laparoscopic surgery, postanesthesia 5% dextrose infusion may be useful in improving the early management of PONV and pain response and may warrant further study.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a significant problem following paediatric surgery, and volatile anaesthetics are an important cause of this phenomenon. BIS-guided anaesthesia, by reducing the consumption of anaesthetics, leads to a decrease in PONV in adult patients. STUDY OBJECTIVE: Evaluate the role of BIS-guided anaesthesia in reducing the incidence of paediatric PONV. DESIGN: Prospective, randomized, double-blind study. SETTING: A single center study in university hospital in Czech republic, from June 2021 to November 2022. PATIENTS: A total of 163 children, aged 3-8 years with ASA I-II who underwent endoscopic adenoidectomy under general anaesthesia were included. INTERVENTIONS: In the intervention group, the depth of anaesthesia was maintained to values between 40 and 60 of BIS. MAIN OUTCOME MEASURE: The primary outcome was the incidence of postoperative nausea and vomiting during 24 h after surgery. RESULTS: The use of BIS-guided anaesthesia led to a significant decrease in the incidence of nausea and vomiting compared to the control group [17% vs. 53%; RR (95%CI) 0.48 (0.27-0.86); p < 0.001and 16% vs. 34%; RR (95%CI) 0.33 (0.20-0.54); p = 0.01, respectively]. CONCLUSIONS: BIS-guided anaesthesia decreases the incidence of postoperative nausea and vomiting in children undergoing adenoidectomy. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT04466579.

INTRODUCTION: Postoperative nausea and vomiting (PONV) is one of the most common adverse events following orthognathic surgery. It's a distressing feeling for patients and continues to be the cause of postoperative complications such as bleeding, delayed healing, and wound infection. This scoping review aims to identify effective PONV prophylaxis strategies during orthognathic surgery that have emerged in the past 15 years. METHODS: We searched Pubmed, Cochrane Controlled Register of Trials, and Embase from 2008 to May 2023. Studies meeting the following criteria were eligible for inclusion: (1) recruited patients undergo any orthognathic surgery; (2) evaluated any pharmacologic or non-pharmacologic method to prevent PONV. Studies meeting the following criteria were excluded: (1) case series, review papers, or retrospective studies; (2) did not report our prespecified outcomes. RESULTS: Twenty-one studies were included in this review. Pharmacological methods for PONV prevention include ondansetron and dexamethasone (3 studies), peripheral nerve block technique (4 studies), dexmedetomidine (1 study), pregabalin (2 studies), nefopam (2 studies), remifentanil (1 study), propofol (2 studies), and penehyclidine (1 study). Non-pharmacologic methods include capsicum plaster (1 study), throat packs (2 studies) and gastric aspiration (2 studies). CONCLUSIONS: Based on current evidence, we conclude that prophylactic antiemetics like dexamethasone, ondansetron, and penehyclidine are the first defense against PONV. Multimodal analgesia with nerve block techniques and non-opioid analgesics should be considered due to their notable opioid-sparing and PONV preventive effect. For the non-pharmacological methods, throat packs are not recommended for routine use because of their poor effect and serious complications. More prospective RCTs are required to confirm whether gastric aspiration can prevent PONV effectively for patients undergoing orthognathic surgery.

BACKGROUND: With the increasing number of bariatric surgeries, the high incidence of postoperative nausea and vomiting (PONV) associated with this surgery has also gradually attracted attention. Among the common bariatric surgery methods, patients undergoing sleeve gastrectomy (SG) have the highest incidence of nausea and vomiting. The mechanism of occurrence of PONV is very complex. This study aims to explore the influencing factors of PONV in patients undergoing laparoscopic sleeve gastrectomy (LSG) and construct a nomogram prediction model based on these factors. METHODS: With the approval of the Ethics Committee, the electronic medical records of patients who underwent LSG from July 2022 to May 2023 were collected retrospectively. RESULTS: A total of 114 patients with complete medical records who underwent LSG from July 2022 to May 2023 were included in this study. Among them, 46 patients developed PONV, resulting in a PONV incidence rate of 40.4%. Multivariate logistic regression analysis revealed that female gender, the use of inhalation anesthesia, and operation time ≥ 120 min were risk factors for PONV in LSG. Additionally, the use of more than two kinds of antiemetic drugs was identified as a protective factor. Based on these factors, a nomogram model was constructed. CONCLUSION: PONV in patients undergoing LSG is related to gender, type of anesthesia, duration of surgery, and combination therapy with antiemetic drugs. The nomogram prediction model constructed in this study demonstrates high accuracy and discrimination in predicting the occurrence of PONV in patients undergoing LSG.

BACKGROUND: Intra-operative anaesthesia management should be optimised to reduce the occurrence of postoperative nausea and vomiting in high-risk patients; however, a single intervention may not effectively reduce postoperative nausea and vomiting in such patients. This study assessed the effect of an optimised anaesthetic protocol versus a conventional one on postoperative nausea and vomiting in patients who underwent laparoscopic sleeve gastrectomy. METHODS: A single-centre randomised trial was conducted at Peking University Shenzhen Hospital from June 2021 to December 2022. Among 168 patients who underwent laparoscopic sleeve gastrectomy, 116 qualified, and 103 completed the study with available data. Patients were categorized into the conventional group (received sevoflurane and standard fluids) and the optimised group (underwent propofol-based anaesthesia and was administered goal-directed fluids). The primary endpoints were postoperative nausea and vomiting incidence and severity within 24 h. RESULTS: Postoperative nausea and vomiting assessment at 0-3 h post-surgery revealed no significant differences between groups. However, at 3-24 h, the optimised anaesthetic protocol group showed lower postoperative nausea and vomiting incidence and severity than those of the conventional group (P = 0.005). In the conventional group, 20 (37.04%) patients experienced moderate-to-severe postoperative nausea and vomiting, compared to six (12.25%) patients in the optimised group (odds ratio = 0.237; 95% CI = 0.086, 0.656; P = 0.006). No significant differences were noted in antiemetic treatment, moderate-to-severe pain incidence, anaesthesia recovery, post-anaesthetic care unit stay, or postoperative duration between the groups. While the total intra-operative infusion volumes were comparable, the optimised group had a significantly higher colloidal infusion volume (500 mL vs. 0 mL, P = 0.014) than that of the conventional group. CONCLUSIONS: The incidence and severity of postoperative nausea and vomiting 3-24 h postoperatively in patients who underwent laparoscopic sleeve gastrectomy were significantly lower with propofol-based total intravenous anaesthesia and goal-directed fluid therapy than with sevoflurane anaesthesia and traditional fluid management. Total intravenous anaesthesia is an effective multimodal antiemetic strategy for bariatric surgery. TRIAL REGISTRATION: This trial was registered with the Chinese Clinical Trial Registry (ChiCTR-TRC- 2,100,046,534, registration date: 21 May 2021).

INTRODUCTION: Despite preventive strategies, vomiting is an adverse event affecting patients with cancer. However, literature on the incidence and risk factors for vomiting in pediatric patients with cancer are scarce. AIM: To assess the incidence and risk factors for vomiting within 24 h and goodness of fit for the Eberhart score in pediatric patients with hematologic cancers after receiving intrathecal chemotherapy under deep sedation. METHODS: This prospective cohort study included patients under 20 years of age with hematologic cancers who were scheduled to undergo intrathecal chemotherapy under anesthesia. The primary outcome was the occurrence of vomiting within 24 h after the end of anesthesia. Sociodemographic and procedure data and underlying diseases were collected. Patients were monitored during the procedure, in the postanesthesia care unit, and the day after (by phone call). RESULTS: A total of 139 patients were included, and the incidence of vomiting was 30.9% within 24 h after intrathecal chemotherapy under anesthesia, with 90.7% of vomiting prior to 6 h. Prophylactic ondansetron was administered prior to the procedure to 45.3% of patients. Risk factors for vomiting were female gender (hazard ratio: 2.47, 95% confidence interval: 1.35-4.53, p: .003), consolidation phase of treatment (hazard ratio: 2.16, 95% confidence interval: 1.10-4.24, p: .025), and history of kinetosis (hazard ratio: 2.49, 95% confidence interval: 1.31-4.70, p: .005). Incidence of vomit was higher than estimated by the Eberhart score distribution (observed incidence in patients with a score of zero: 33.3%; with a score of one: 28.8%; with a score of two: 60%). CONCLUSION: A high incidence of vomiting was observed within 24 h after intrathecal chemotherapy under propofol deep sedation. Risk factors for this outcome were established (being female, consolidation phase of treatment, and previous kinetosis), and evidence suggested that the Eberhart score was not suitable for the studied population.

OBJECTIVE: The aim of this study was to develop a web-based dynamic prediction model for postoperative nausea and vomiting (PONV) in patients undergoing gynecologic laparoscopic surgery. METHODS: The patients (N = 647) undergoing gynecologic laparoscopic surgery were included in this observational study. The candidate risk-factors related to PONV were included through literature search. Lasso regression was utilized to screen candidate risk-factors, and the variables with statistical significance were selected in multivariable logistic model building. The web-based dynamic Nomogram was used for model exhibition. Accuracy and validity of the experimental model (EM) were evaluated by generating receiver operating characteristic (ROC) curves and calibration curves. Hosmer-Lemeshow test was used to evaluate the goodness of fit of the model. Decision curve analysis (DCA) was used to evaluate the clinical practicability of the risk prediction model. RESULTS: Ultimately, a total of five predictors including patient-controlled analgesia (odds ratio [OR], 4.78; 95% confidence interval [CI], 1.98-12.44), motion sickness (OR, 4.80; 95% CI, 2.71-8.65), variation of blood pressure (OR, 4.30; 95% CI, 2.41-7.91), pregnancy vomiting history (OR, 2.21; 95% CI, 1.44-3.43), and pain response (OR, 1.64; 95% CI, 1.48-1.83) were selected in model building. Assessment of the model indicates the discriminating power of EM was adequate (ROC-areas under the curve, 93.0%; 95% CI, 90.7%-95.3%). EM showed better accuracy and goodness of fit based on the results of the calibration curve. The DCA curve of EM showed favorable clinical benefits. CONCLUSIONS: This dynamic prediction model can determine the PONV risk in patients undergoing gynecologic laparoscopic surgery.

BACKGROUND: We investigated whether 2 doses of dexamethasone are more effective than a single dose in reducing early postoperative nausea and vomiting (PONV) during total knee arthroplasty (TKA). METHODS: A total of 150 patients between June 2021 and June 2022 were randomized into 3 groups: 2 doses of normal saline (group A), a single dose of 10 mg dexamethasone before surgery and normal saline after surgery (group B), and 2 doses of 5 mg dexamethasone during the perioperative period (group C). Primary outcomes were incidences and severity of PONV within 24 hours after surgery, the number and consumption of patients requiring morphine and metoclopramine, and visual analog scale scores for nausea and vomiting at 2, 4, 6, and 24 hours after surgery. Blood glucose levels on days 1, 2, and 3 after operation and incidences of surgical site infection (SSI) as well as gastrointestinal bleeding (GIB) within 45 days after operation were compared. RESULTS: Within 24 hours after operation, the number and consumption of patients requiring morphine and metoclopramide in groups B and C were significantly lower than those in group A. Incidences and severity of PONV in groups B and C were significantly lower than those in group A. And these differences between groups B and C were significant. At 2, 4, 6, and 24 hours after operation, there were significant differences in visual analog scale scores of PONV between groups A and B, A and C, as well as B and C. On postoperative days 1, 2, and 3, there were no significant differences in blood glucose levels among the groups, and there were no incidences of SSI or GIB in any group within 45 days after operation. CONCLUSION: Dexamethasone significantly reduces PONV within 24 hours after TKA, does not result in significant changes in postoperative blood glucose levels, and does not increase the risk of SSI or GIB, particularly on group C.

RESUMO
AIMS: To compare anaesthesia-related outcomes between patients monitored by newly recruited nurse anaesthetists and those monitored by newly recruited anaesthesiologists. DESIGN: This was a retrospective study. METHODS: We conducted a retrospective study that collected demographic information on newly recruited nurse anaesthetists and anaesthesiologists between 2017 and 2022 and recorded information on patients within 6 months of monitoring. Postoperative pain, emergency agitation, nausea, and vomiting were designated anaesthesia-related outcomes. Propensity score matching was used to adjust for covariates. The study adhered to the STROBE guidelines. RESULTS: The study's statistical analysis included 4483 patients monitored by 22 newly recruited nurse anaesthetists and 4959 patients monitored by 23 newly recruited anaesthesiologists. Compared with patients monitored by newly trained anaesthesiologists, the patients monitored by nurse anaesthetists were younger (42.07 ± 20.00 vs. 47.39 ± 18.45 years, p < 0.001) and had a lower body mass index (23.56 ± 4.46 vs. 24.19 ± 4.25, p < 0.001). Patients monitored by anaesthesiologists had a greater proportion of women (61.62% vs. 59.25%, p < 0.001), a high proportion of ASA III and ASA IV (17.1% vs. 8.88%, p < 0.001), and a longer mean surgery duration (78.65 ± 59.01 vs. 70.70 ± 60.65 min, p < 0.001). After propensity score matching was used to adjust for covariates, no statistically significant differences were found in the prevalence of postoperative pain, emergency agitation, or postoperative nausea and vomiting between the two groups (p < 0.05). CONCLUSION: Nurse anaesthetists monitoring alone during anaesthesia maintenance is feasible and safe. The two groups had no significant differences in the incidence of postoperative pain, emergency agitation, or postoperative nausea and vomiting. RELEVANCE TO CLINICAL PRACTICE: The shortage of anaesthesiologists leads to heavy work burden and high incidence of occupational burnout among anaesthesiologists. The study found that it was safe for nurse anaesthetists to perform anaesthetic monitoring alone in the operating room under the supervision of the attending anaesthesiologist and did reduce the burden of anaesthesiologists' work. The results of the current study contribute to the expansion of occupational categories for nurse anaesthetists in countries where anaesthesiologists are in short supply. It provides new ideas for hospital administrators and policy-makers to formulate medical and nursing service policies.

Opioid administration is particularly challenging in the perioperative period. Computerized-based Clinical Decision Support Systems (CDSS) are a promising innovation that might improve perioperative pain control. We report the development and feasibility validation of a knowledge-based CDSS aiming at optimizing the management of perioperative pain, postoperative nausea and vomiting (PONV), and laxative medications. This novel CDSS uses patient adaptive testing through a smartphone display, literature-based rules, and individual medical prescriptions to produce direct medical advice for the patient user. Our objective was to test the feasibility of the clinical use of our CDSS in the perioperative setting. This was a prospective single arm, single center, cohort study conducted in Strasbourg University Hospital. The primary outcome was the agreement between the recommendation provided by the experimental device and the recommendation provided by study personnel who interpreted the same care algorithm (control). Thirty-seven patients were included in the study of which 30 (81%) used the experimental device. Agreement between these two care recommendations (computer driven vs. clinician driven) was observed in 51 out 54 uses of the device (94.2% [95% CI 85.9-98.4%]). The agreement level had a probability of 86.6% to exceed the 90% clinically relevant agreement threshold. The knowledge-based, patient CDSS we developed was feasible at providing recommendations for the treatment of pain, PONV and constipation in a perioperative clinical setting.Trial registration number & date The study protocol was registered in ClinicalTrial.gov before enrollment began (NCT05707247 on January 26th, 2023).

PURPOSE: To investigate the association between adherence to guideline-recommended risk-based postoperative nausea and vomiting (PONV) prophylaxis, the antiemetics used for PONV prophylaxis, and the incidence of PONV in patients who were underwent general anesthesia before and after 5-HT3 receptor antagonists became available. METHODS: Patients (≥ 20 years old) who were extubated after scheduled surgery and returned to general wards between January 2021 and February 2022 and between June 2022 and July 2023 were included. Risk factors included age < 50, female, motion sickness, nonsmoker, surgical factors, and postoperative opioid use. Two and three or more prophylaxis were recommended for patients with one or two and three or more risk factors, respectively. The primary outcome was the number of patients who received adequate prophylaxis, and the secondary outcomes were antiemetic agents used during anesthesia and the incidence of PONV on postoperative days 0 and 1. PONV was defined as documented PONV or rescue antiemetic administration. RESULTS: From January 2021 to February 2022 and from June 2022 to July 2023, 2342 and 2682 patients were included, respectively. Before ondansetron became available, more D2 receptor antagonists were used (p < 0.001), and after ondansetron became available, both ondansetron (p < 0.001) and propofol (p < 0.001) were given more frequently. Before and after ondansetron became available, the number of patients with adequate prophylaxis was 3.7% and 9.2%, respectively (p < 0.001), and the incidence of PONV on postoperative days 0 and 1 was 44.6% and 44.0%, respectively (p = 0.67). CONCLUSION: The availability of ondansetron increased the number of patients with adequate PONV prophylaxis, but did not decrease the incidence of PONV.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a frequent adverse effect following laparoscopic sleeve gastrectomy. Palonosetron with a standard dosing (75 µg) schedule has been questioned due to its low efficiency in obese patients. This study aimed to investigate the effectiveness and safety of the body weight-based dosing of palonosetron in managing PONV following laparoscopic sleeve gastrectomy. METHODS: A single-center, prospective, double-blinded randomized study was conducted between August 2021 and December 2021. Patients who underwent laparoscopic sleeve gastrectomy were prospectively recruited in the study. One hundred patients were randomly divided into palonosetron (Group P) and ondansetron (Group O). The demographic and clinical variables were recorded. The primary outcome of the study was the incidence of PONV between the two groups during the hospitalization. The secondary outcomes were the number of rescue anti-emetic and analgesic medications and the Functional Living Index-Emesis scores. RESULTS: There were 50 patients in each group (Group P and Group O). There were significant differences in the scores of POVN, nausea, and vomiting favoring Group P. In Group P, the rate of patients using rescue anti-emetics was significantly lower. The incidence of complete response and proportion of patients with higher Functional Living Index-Emesis scores were significantly higher in patients using palonosetron. CONCLUSIONS: The use of palonosetron significantly reduced the incidence of PONV following laparoscopic sleeve gastrectomy. There was a significant improvement in the scores of Functional Living Index-Emesis in patients using palonosetron.

PURPOSE: This study aims to assess the impact of nonpharmacological nursing interventions on postoperative nausea and vomiting (PONV). DESIGN: This is a systematic review. METHODS: MEDLINE, Web of Science, ScienceDirect, Tübitak-ULAKBIM, and TRDizin databases were searched for the following search terms, including "Postoperative Nausea and Vomiting," "Nurse," "Nursing," and "Nonpharmacological Interventions" to identify nonpharmacological nursing interventions for PONV. A systematic review of English and Turkish articles published in the period between January 1, 2012 and June 1, 2023 was conducted. The PICOT-SD method was used to determine the compatibility of the pieces with the eligibility criteria. FINDINGS: Fifty-eight of 3,874 articles obtained from databases fulfilled the eligibility criteria. This study demonstrated that acupuncture, aromatherapy, the oral intake of ginger, listening to music, education, and visits to patients decreased the incidence of nausea and vomiting and increased the quality of life. Additionally, it was found that patients' quality of life tended to improve along with reductions in postoperative complications. CONCLUSIONS: The results of this study support previous findings in the literature and demonstrate that nonpharmacological nursing interventions help reduce and prevent PONV. Based on our results, we suggest that nonpharmacological nursing interventions can be employed for the management of PONV in patients undergoing surgery.
