BackgroundPostoperative pain and analgesia present challenges in bariatric surgery patients. Multimodal analgesia may provide better efficacy, less complications and expedite fast-track bariatric surgical care. There are no studies of the broader topic of perioperative analgesia and the overall impact. This study highlights the impact of multimodal intraoperative analgesia on fast-track bariatric surgery.MethodsThis observational study examined the perioperative outcome data of 412 consecutive laparoscopic bariatric surgery patients over a 6-year period. Perioperative outcome and variables were analysed and compared between different intraoperative analgesia types.ResultsMean BMI was 49, mean age was 42 and male:female ratio was 1:4. About 82% of patients received multimodal intraoperative analgesia, comprising various combinations of bupivacaine infiltration and intravenous acetaminophen, morphine, tramadol, parecoxib or diclofenac. Morphine was administered in 83% of patients and tramadol in 17%. Multimodal intraoperative analgesia provided better postoperative analgesia, shorter postanaesthesia care unit (PACU) duration, lower postoperative opioid requirement, less postoperative vomiting, earlier postoperative oral intake, earlier ambulation and shorter hospital stay compared to unimodal intraoperative morphine analgesia (p = 0.0001). Multimodal analgesia comprising tramadol + acetaminophen + diclofenac provided better postoperative analgesia, shorter PACU duration, lower postoperative opioid requirement, earlier ambulation, shorter hospital stay and less postoperative hypopnoea compared to patients who received morphine (p = 0.0001).ConclusionsMultimodal intraoperative analgesia provides better postoperative analgesia, less complications and better perioperative outcomes and facilitates fast-track bariatric surgical care. Tramadol is suitable, efficacious and safe and associated with the best perioperative outcomes in bariatric surgery patients.
