What this Trial Is About
This research aims to compare two types of ultrasound-guided nerve blocks, the external oblique intercostal plane (EOIP) block and the subcostal transversus abdominis plane (TAP) block, for managing pain in patients undergoing laparoscopic sleeve gastrectomy. The study focuses on how well each block reduces pain, how long the pain relief lasts, and the total opioid use after surgery. Effective pain control is an important part of recovery after bariatric surgery, and these blocks target nerves supplying the upper abdomen. Participants will be randomly assigned to receive either a bilateral EOIP block or a bilateral subcostal TAP block. Both blocks involve ultrasound guidance and use 20 mL of 0.25% bupivacaine on each side, administered after anesthesia induction and before surgery starts. The study compares these two approaches to see which provides better pain relief during and after surgery. During the study, researchers will monitor participants' opioid use within the first 24 hours after surgery as the main outcome. They will also assess the time to first rescue pain medication, pain levels, heart rate, blood pressure during surgery, nausea and vomiting, any complications related to the blocks, and patient satisfaction within 24 hours postoperatively. This careful monitoring helps understand the benefits and risks of each technique for managing pain after laparoscopic sleeve gastrectomy.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Up to 2 hours (duration of surgery and immediate recovery)
Participants receive an ultrasound-guided nerve block after anesthesia induction and prior to surgery to manage pain during laparoscopic sleeve gastrectomy. Pain relief and vital signs are monitored during and immediately after surgery.
1 surgery visit including anesthesia and nerve block administration
Duration - 24 hours postoperatively
Participants are monitored for pain levels, opioid use, nausea, block-related complications, and overall satisfaction during the 24 hours after surgery.
Approximately 1 follow-up visit within 24 hours after surgery
