Efficacy of Preventive Ketamine on Postoperative Pain

• Status: Recruiting
• Trial end date: 2021-12-15
• Target enrollment: 0
• Participant gender: All

Summary

• Although bariatric surgery is mainly performed laparoscopically, analgesic optimization is still essential to reduce complications and to improve the patients' comfort. In laparoscopic sleeve gastrectomy, the intraoperative peritoneal instillation of bupivacaine hydrochloride (30 ml, 0.25%) was known to be safe and effective in reducing postoperative pain, nausea, and vomiting.

• Furthermore, usage of ketamine both as a pre and post-operative pain management is well established. Ketamine can be used solely or in combination with other co-adjuvant drugs, increasing their efficacy. Many therapeutic properties of ketamine have been attributed to its antagonism mechanism to N-Methyl-D-aspartate receptors.
