Brief Summary: Laparoscopic gastric sleeve and bypass surgeries the most common bariatric procedures for weight loss and improved management of metabolic syndromes. Patients may suffer from wound pain or referred pain after laparoscopic bariatric operation. Most importantly, 11.8% of these patients complained surgical-related pain one year after operation, and 8% of them required prolonged use of opioid to control chronic postoperative pain (CPSP). However, there are currently lack of clinical practice guidelines or recommendations for prevention of CPSP after laparoscopic abdominal surgery. Although regional block techniques (i.e. truncal block or intrathecal opioid) are considered as effective supplementary analgesic approaches to improve postoperative pain control, parenteral administration of analgesics remain as the mainstay for pain management of laparoscopic abdominal surgery. Naldebain® is prodrug of nalbuphine, which was approved by the Taiwan FDA in 2017. Naldebain® is an extended-release dinalbuphine sebacate, and is rapidly hydrolyzed by tissue of plasma esterase to release nalbuphine. A number of clinical studies have shown that single-dose of pre-operative intramuscular administration of Naldebain® provides significantly higher analgesic effect up to 1 week in hemorrhoidectomy and laparotomy surgery with a well-tolerated safety profile. Therefore, this PI-initiated randomized, double-blind, placebo-control trial aims to investigate the clinical efficacy of Naldebain® in management of acute postoperative pain in patients receiving laparoscopic gastric sleeve or bypass surgery, and prevention of the development of CPSP after surgery. This study will also analyze the plasma levels of nalbuphine following a single intramuscular injection in obese patients.
Detailed Description: Clinical studies indicate that more than 80% of patients suffer from surgical-related pain in the first few days after major laparotomy or laparoscopic abdominal surgery and about 10% of these patients may develop chronic postoperative pain (CPSP), which can last up to several years after surgery. One of the major risk factors for developing CPSP is inadequate management of the acute postoperative pain. Laparoscopic gastric sleeve and bypass surgeries the most common bariatric procedures for weight loss and improved management of metabolic syndromes. Patients may suffer from wound pain or referred pain after laparoscopic bariatric operation. Most importantly, 11.8% of these patients complained surgical-related pain one year after operation, and 8% of them required prolonged use of opioid to control CPSP. However, there are currently lack of clinical practice guidelines or recommendations for prevention of CPSP after laparoscopic abdominal surgery. Although regional block techniques (i.e. truncal block or intrathecal opioid) are considered as effective supplementary analgesic approaches to improve postoperative pain control, parenteral administration of analgesics remain as the mainstay for pain management of laparoscopic abdominal surgery. Nalbuphine is a semi-synthetic opioid that acts as a mixed kappa opioid agonist and mu opioid antagonist, but its clinical applications in relieving acute postoperative pain is limited by the relatively short duration of action of 3-6h. Naldebain® is prodrug of nalbuphine, which was approved by the Taiwan FDA in 2017. Naldebain® is an extended-release dinalbuphine sebacate, and is rapidly hydrolyzed by tissue of plasma esterase to release nalbuphine. A number of clinical studies have shown that single-dose of pre-operative intramuscular administration of Naldebain® provides significantly higher analgesic effect up to 1 week in hemorrhoidectomy and laparotomy surgery with a well-tolerated safety profile. Naldebain® has not been tested in laparoscopic bariatric surgery and its pharmacokinetic profiles in overweight patients are undetermined. Therefore, this PI-initiated randomized, double-blind, placebo-control trial aims to investigate the clinical efficacy of Naldebain® in management of acute postoperative pain in patients receiving laparoscopic gastric sleeve or bypass surgery, and prevention of the development of CPSP after surgery. This study will also analyze the plasma levels of nalbuphine following a single intramuscular injection in obese patients.
