Clinical Trial Summary

The purpose of this study to compare erector spinae block to transversus abdominis plane block in bariatric surgeries regarding analgesic efficacy and postoperative oxygenation and respiratory complications

Description:

The erector spinae plane (ESP) block is an interfascial block proposed to provide analgesia for chronic pain and perioperative period. it can provide both visceral and somatic abdominal analgesia if the injection were performed at a lower thoracic level. ESP block is effective, easy to perform, and can be performed in a short time. Therefore, bilateral ESP block may have comparable or improved analgesic effect in upper and lower abdominal surgical procedures when compared to other suitable plane blocks. Transversus abdominis plane (TAP) block technique is to reduce postoperative pain and is a part of current analgesic regimen for many abdominal surgeries . Moreover, it was found that posterior TAP block appears to produce more prolonged analgesia than the lateral TAP block. Ultrasound guided TAP block is a feasible, minimally invasive technique . It reduces the postoperative requirement of opioid analgesics, decreases the incidence and severity of postoperative nausea and vomiting, improves patient satisfaction, and allows early readiness for discharge postoperatively. Both blocks is effective in reducing postoperative complication and need of analgesia , To our knowledge there is no comparative study between the two blocks to this population . the investigators aim to compare the perioperative analgesic effect between TAP block and ES block in bariatric .
