Effect of balanced opioid-free anaesthesia on postoperative nausea and vomiting after video-assisted thoracoscopic lung resection: protocol for a randomised controlled trial.

ABSTRACT:

Introduction

Opioid-free anaesthesia (OFA) may reduce opioid-related side effects such as postoperative nausea and vomiting (PONV) and hyperalgesia. This study aims to investigate the effects of balanced OFA on PONV and pain outcomes in patients undergoing video-assisted thoracoscopic surgery (VATS).

Methods and analysis

This randomised controlled trial will be conducted at the First Affiliated Hospital of Soochow University in Suzhou, China. A total of 120 adults scheduled for VATS lung resection will be randomly assigned with a 1:1 ratio to either an OFA group or a control group, stratified by sex (n=60 in each group). Patients will receive balanced anaesthesia with esketamine, dexmedetomidine and sevoflurane (the OFA group), or sufentanil and sevoflurane (the control group). All patients will receive PONV prophylaxis with intraoperative dexamethasone and ondansetron. Multimodal analgesia consists of intraoperative flurbiprofen axetil, ropivacaine infiltration at the end of surgery and postoperative patient-controlled sufentanil. The primary outcome is the incidence of PONV within 48 hours after surgery. Secondary outcomes are nausea, vomiting, need for antiemetic therapy, pain scores at rest and while coughing, postoperative sufentanil consumption, need for rescue analgesia, length of post-anaesthesia care unit stay, length of postoperative hospital stay, and 30-day and 90-day post-surgical pain and mortality. Safety outcomes are hypotension, bradycardia, hypertension, tachycardia, interventions for haemodynamic events, level of sedation, headache, dizziness, nightmare and hallucination. All analyses will be performed in the modified intention-to-treat population.

Ethics and dissemination

Ethics approval was obtained from the Ethics Committee of the First Affiliated Hospital of Soochow University (2022-042). All patients will provide written informed consent. The results of this study will be published in a peer-reviewed journal.

Project description:ObjectivesOpioid-free anaesthesia (OFA) has emerged as a promising approach for mitigating the adverse effects associated with opioids. The objective of this study was to evaluate the impact of OFA on postoperative nausea and vomiting (PONV) following video-assisted thoracic surgery.DesignSingle-centre randomised controlled trial.SettingTertiary hospital in Shanghai, China.ParticipantsPatients undergoing video-assisted thoracic surgery were recruited from September 2021 to June 2022.InterventionPatients were randomly allocated to OFA or traditional general anaesthesia with a 1:1 allocation ratio.Primary and secondary outcome measuresThe primary outcome measure was the incidence of PONV within 48 hours post-surgery, and the secondary outcomes included PONV severity, postoperative pain, haemodynamic changes during anaesthesia, and length of stay (LOS) in the recovery ward and hospital.ResultsA total of 86 and 88 patients were included in the OFA and control groups, respectively. Two patients were excluded because of severe adverse events including extreme bradycardia and epilepsy-like convulsion. The incidence and severity of PONV did not significantly differ between the two groups (29 patients (33.0%) in the control group and 22 patients (25.6%) in the OFA group; relative risk 0.78, 95% CI 0.49 to 1.23; p=0.285). Notably, the OFA approach used was associated with an increase in heart rate (89±17 vs 77±15 beats/min, t-test: p<0.001; U test: p<0.001) and diastolic blood pressure (87±17 vs 80±13 mm Hg, t-test: p=0.003; U test: p=0.004) after trachea intubation. Conversely, the control group exhibited more median hypotensive events per patient (mean 0.5±0.8 vs 1.0±2.0, t-test: p=0.02; median 0 (0-4) vs 0 (0-15), U test: p=0.02) during surgery. Postoperative pain scores, and LOS in the recovery ward and hospital did not significantly differ between the two groups.ConclusionsOur study findings suggest that the implementation of OFA does not effectively reduce the incidence of PONV following thoracic surgery when compared with traditional total intravenous anaesthesia. The opioid-free strategy used in our study may be associated with severe adverse cardiovascular events.Trial registration numberChiCTR2100050738.

Project description:BackgroundCough is one of the shared complications after lung surgery. In this study, a prospective analysis was conducted for exploring the risk factors of persistent cough after uniportal video-assisted thoracoscopic pulmonary resection.MethodsOne hundred thirty-five patients with pulmonary nodules who underwent surgical treatment in the same surgical group from November 2019 to January 2020 were enrolled in this prospective study. The severity of cough and its impact on patients' quality of life before and after surgery were assessed by the Mandarin Chinese version of the Leicester cough questionnaire (LCQ-MC), and postoperative cough was tested by the cough visual analog scale (VAS) and cough symptom score (CSS). Risk factors of cough after pulmonary resection (CAP) were determined by univariate and multivariate logistic regression analysis.ResultsThe incidence of postoperative cough was 24.4% (33 of 135 patients). Univariate analysis showed that gender (female), the surgical site (upper right), the resection (lobectomy), subcarinal lymph node dissection, postoperative acid reflux, length of hospitalization contributed to the development of CAP resection. Multivariate logistic regression analysis showed that the resection (lobectomy) (OR 3.590, 95% CI: 0.637-20.300, P=0.017), subcarinal lymph node dissection (OR 4.420, 95% CI: 1.342-14.554, P=0.001), postoperative acid reflux (OR 13.55, 95% CI: 3.186-57.633, P<0.001) and duration of anesthesia (over 153 minutes, OR 0.987, 95% CI: 0.978-0.997, P=0.011) were independent risk factors for postoperative cough.ConclusionsThe application of uniportal video-assisted thoracoscopic techniques to several types of lung surgery are conducive to enhanced recovery after surgery (ERAS). Postoperative cough is related to an ocean of factors, the resection (lobectomy), subcarinal lymph node dissection, postoperative acid reflux, and duration of anesthesia (over 153 minutes) are independent high-risk factors for CAP resection.Trial registrationThis study was registered on ClinicalTrials.gov (NCT04204148).

Project description:BackgroundIn recent years, single-hole thoracoscopic surgery technology is widely used in major medical centers and chest-specialized hospitals for the treatment of lung diseases. However, the single-hole minimally invasive surgery method focuses on one incision, and all surgical instruments need to pass through the same hole, resulting in repeated extrusion and tissue damage of the surgical incision. Therefore, we have improved the suture method of conventional surgical incision in order to reduce the probability of wound infection and dehiscence, promote early healing, and reduce the severity of postoperative wound scar, thereby enhancing the postoperative rapid recovery of patients. The purpose of this study is to explore the clinical efficacy of a modified surgical incision suture technique applied to uniportal thoracoscopic pulmonary resection.MethodsThis study retrospectively analyzed 151 patients who were admitted to the Department of Thoracic Surgery and underwent pulmonary resection from January 2019 to October 2021 in the North District of Suzhou Municipal Hospital. The patients were divided into two groups according to the different surgical incision suture methods: a modified group and a conventional group. The postoperative general clinical indexes, incision infection rate, secondary suture rate, postoperative incision pain score, and the severity of postoperative incision scar were compared and analyzed between the two groups.ResultsThere were no statistically significant differences between the two groups in terms of chest tube duration or postoperative drainage and postoperative incision pain scores; the incision infection rate (1.3% vs. 6.7%, P<0.05), secondary suture rate (2.6% vs. 9.4%, P<0.05), and postoperative scar score (4.853 vs. 5.543, P=0.03) were better in the modified group than in the conventional group, and the differences between the two groups were statistically significant.ConclusionsOur modified suture method reduces the chance of infection and splitting and the severity of postoperative incision scar formation, promoting early healing. It can be safely and effectively applied to the incision suture of uniportal thoracoscopic pulmonary resection, enhancing the rapid postoperative recovery of patients.
