Study summary

Bariatric surgery remains the most effective therapy for obesity. Postoperative nausea and vomiting (PONV) are commonly reported following bariatric surgery. The proposed study focuses on the most common bariatric procedure performed, laparoscopic sleeve gastrectomy (LSG), and aims to assess the effect of a post-operative nausea and vomiting-specific intervention. The investigators hypothesize that the intervention group will experience a reduction of nausea-related prolonged hospital stay and significantly improve patient-reported quality of recovery from surgery and quality of life.

Read the detailed description

To test this hypothesis, participants undergoing sleeve gastrectomy will be randomized to two groups: control vs Nausea specific-intervention group. All subjects will be assessed with a nausea specific questionnaire at 1, 4, 12, 24 hours and 3 weeks after surgery. Patient satisfaction with recovery will be assessed using specialized questionnaires at baseline, 24 hrs. and 3 weeks following surgery. Serial assessments of nausea, vomiting, quality of life and quality of recovery, will allow the investigators to identify an effect on incidence and severity of Post-operative Nausea and Vomiting. Importantly, the investigators will evaluate for an impact in patient-reported measures of quality of life.

The total sample size is 83. This study will provide valuable insight on the epidemiology of post-operative nausea and vomiting after hospital discharge following Sleeve gastrectomy, which is currently poorly characterized. By allowing the investigators to assess the overall incidence of nausea and vomiting at different time points, this study will afford the opportunity to identify a time period of high incidence and further adjust our prevention efforts accordingly in future studies.

Study arms

  • Experimental
    Intervention Arm

    A) Pre-operatively: aprepitant 80 mg oral capsule and scopolamine transdermal patch. B) Intra-operatively: total intravenous anesthesia (TIVA) will be maintained with IV infusions of propofol, and dexmedetomidine infusion or intermittent bolus dosing of fentanyl after induction. Sugammadex (2-4 mg/Kg IV) will be used for reversal of neuromuscular blockade in both groups. A single dose of dexamethasone 8 mg IV will be administered after induction, and a single dose of ondansetron 4 mg IV will be administered approximately 20 minutes prior to the end of operation. C) Post-operatively: Scheduled ondansetron and Raglan every 6 hours, using Compazine as a rescue medication.

  • Active comparator
    Control Arm

    A) Pre-operatively: No intervention B) Intra-operatively: inhalation anesthetics (sevoflurane or desflurane) and intermittent opioid boluses will be used for maintenance of anesthesia, as standard practice in the institution of the investigators and across the country. PONV prevention measures in the control group will be limited to dexamethasone 8 mg and ondansetron 4 mg. C) Post-operatively: Scheduled ondansetron and Raglan every 6 hours, using Compazine as a rescue medication.

What researchers measure

Primary outcomes

  1. Number of Participants With PONV-related Delay of Hospital Discharge

    The primary outcome would be incidence of PONV-related delay of hospital discharge following laparoscopic gastrectomy. Based on the current clinical pathway, patients are expected to be discharged on postoperative day 1 (day after surgery). A delay in discharge due to PONV will be the primary outcome.

    Time frame: up to 1 week post-operation (up to 2 weeks from baseline)

Secondary outcomes

  1. Severity of PONV Measured Using a 10-point Verbal Rating Scale.

    The severity of PONV will be measured using a visual analogue scale. \[0-10\] The higher the value, the worse the outcome.

    Time frame: Baseline, 1 hour, 4 hours, 12 hours, 24 hours and 3 weeks

  2. Severity of PONV Measured Using the Rhodes Index

    The Rhodes Index of Nausea, Vomiting, and Retching (R-INVR) is a validated instrument used to measure the severity of Post-Operative Nausea and Vomiting (PONV). The index comprises eight items, each scored on a scale of 0 to 4, allowing for a total score range of 0 to 32 points . The scoring of each item on the Rhodes Index is as follows: 0 points represent a minimum level of disturbance, 4 points represent a maximum level of disturbance . The total score from these eight items is summed to represent the severity of PONV, with higher scores indicating worse PONV experience. The index encompasses three subscales named "experience," "occurrence," and "distress" . Each of these subscales contributes to the total score to provide a comprehensive measure of PONV severity. Any score above zero on the R-INVR indicates that the participant experienced nausea .

    Time frame: Baseline, 1 hour, 4 hours, 12 hours, 24 hours and 3 weeks

  3. Quality of Recovery Measured Using the Quality of Recovery QoR-15 Survey

    The quality of recovery-15 (QoR-15) is a patient-reported outcome measurement measuring QoR after surgery and anesthesia. The scale is arbitrary and ranges from 0 to 150. The higher the score, the worse the outcome.

    Time frame: 24 hours and 3 weeks

  4. GI Specific Quality of Life Using the Gastrointestinal Quality of Life (GIQLI) Survey

    The GIQLI is a 36-item patient reported outcomes instrument designed to assess GI-specific health-related quality of life in clinical practice and clinical trials of patients with GI disorders. It has five domains (GI symptoms, emotion, physical function, social function and medical treatment) and sub-scores range from 0-4 while the total score range from 0-144. Higher scores mean better GI health-related quality of life.

    Time frame: Baseline, 24 hours and 3 weeks

  5. Overall Quality of Life Using the EuroQol- 5 Dimension (EQ-5D) Instrument

    EQ-5D Descriptive System: Dimensions: Includes five dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression. Levels: Each dimension has 5 severity levels: 1. No problems 2. Slight problems 3. Moderate problems 4. Severe problems 5. Extreme problems Time Frame: Assessed at baseline, 24 hours post-baseline, and 3 weeks.

    Time frame: Baseline, 24 hours and 3 weeks
