Overview
Brief 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
Detailed 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 .

Arms & Interventions
TAP block group
the TAP block will be given by a high frequency linear ultrasound transducer of Siemens acuson x300 3-5MHz ultrasound . a blunted tip , 20-gauge, short bevel needle (Pajunk Sonoplex, Geisingen, Germany) will be used under direct ultrasound visualization, . After confirming the correct placement of the needle and the negative aspiration probe anaesthetic substance will be injected along the subcostal line in the transversus abdominis plane 20 ml 0.25% bupivacaine(10) , and the dissection of the plane was observed. The block will be performed bilaterally.
Intervention: transversus abdominis block

ESP group
the Erector Spinae block will be given by a high-frequency linear ultrasound transducer of Siemens acuson x300 3-5MHz ultrasound .A blunted tip , 20-gauge, short bevel needle (Pajunk Sonoplex, Geisingen, Germany) will be used under strict aseptic precautions until the tip is deep to erector spinae muscle, The block will be performed bilaterally by injecting 40 mL of 0.25% bupivacaine (20 mL into each side) into the fascial plane between the deep surface of the Erector Spinae muscle and the transverse processes of the lumbar vertebrae laterally
