Postoperative Pain After Laparoscopic Sleeve Gastrectomy
Conditions
Brief summary
One of most common bariatric surgery is laparoscopic sleeve gastrectomy. Pain after laparoscopic surgery may be due to stretching of the intra-abdominal cavity, peritoneal inflammation, and diaphragmatic irritation caused by residual carbon-dioxide in the peritoneal cavity.Multimodal efforts like parenteral opioids, non-steroidal anti-inflammatory drugs or local wound infiltration have been done to reduce overall pain and benefit post-operative conditions of patients undergoing laparoscopic surgeries. Despite their efficacy, with all parenteral medications, there are associated adverse effects. Intraperitoneal local anesthetic is a safe and effective analgesic approach which used to control pain after laparoscopic surgery. Many authors have evaluated the role of IP local anesthetic administration in laparoscopic colorectal cancer surgery, laparoscopic cholecystectomy, laparoscopic appendectomy and laparoscopic hysterectomy
Detailed description
Laparoscopic procedures have many advantages over open procedures such as lesser haemorrhage, better cosmetic results, lesser post-operative pain, and shorter recovery time, leading to shorter hospital stay and less expenditure.One of most common bariatric surgery is laparoscopic sleeve gastrectomy. Pain after laparoscopic surgery may be due to stretching of the intra-abdominal cavity, peritoneal inflammation, and diaphragmatic irritation caused by residual carbon-dioxide in the peritoneal cavity. Multimodal efforts like parenteral opioids, non-steroidal anti-inflammatory drugs or local wound infiltration have been done to reduce overall pain and benefit post-operative conditions of patients undergoing laparoscopic surgeries. Despite their efficacy, with all parenteral medications, there are associated adverse effects. Intraperitoneal local anesthetic is a safe and effective analgesic approach which used to control pain after laparoscopic surgery. Many authors have evaluated the role of IP local anesthetic administration in laparoscopic colorectal cancer surgery, laparoscopic cholecystectomy, laparoscopic appendectomy and laparoscopic hysterectomy. Dexmedetomidine (alpha-2 adrenergic agonists) has become one of the frequently used drugs in anesthesia as it has been reported to provide analgesia, anxiolysis, and an anesthetic-sparing action with minimal respiratory depression plus its sedative effect that mimics natural sleep. Dexmedetomidine can used safely both intravenous and plus bupivacaine in different nerve block.
Interventions
PROCEDUREintraperitoneal local anaesthetic instillation
intraperitoneal anesthetic instillation (40 ml total volume containing bupivacaine 0.25) through the trocar at the subdiaphragmatic space in Trendelenburg's position for 5 min with intravenous infusion of 50 ml normal saline over 10 minutes.
