Summary

assess the efficacy of ultrasound guided erector spinae block to decrease the requirement for analgesics after laparoscopic sleeve gastrectomy and to decrease postoperative pain scores and opioid consumption compared to subcostal transverses abdominis block.

Detailed description

Primary outcomes • Cumulative opioid consumption during the first 24 h postoperatively. For the purpose of comparison, all opioids administered postoperatively will be converted to IV morphine equivalent doses using standard opioid dosage conversion tables. Secondary outcome parameters 1. Pain assessment by the aid of Visual analogue scale (VAS), which is consisted of a "10 cm" line with one end labeled no pain and other end labeled worst intolerable pain. The patients marked the line at the point that best describing the pain intensity. The preoperative assessment included training of the patients about (VAS) for postoperative pain. The length of the line to the patient's mark will be measured and recorded postoperative after 30 min., 4, 6, 8, and 24 hours. 2. Failure rate of the block will be calculated, where the block will be considered a failed block if the patient requires more than two doses of rescue analgesia in the first hour postoperatively. 3. Duration of surgery (from skin incision till skin closure) and general anesthesia (from induction of GA till extubation). 4. Incidence of complications, such as: Nerve injury, Hematoma formation, LA toxicity, and intravascular injection.

Type	Name	Description
PROCEDURE	Erector spinae plane block	the level between T9 and T10 will be identified using ultrasound as well as transverse processes depth. An array probe will be applied longitudinal orientation 3 cm lateral midline. The erector spinae and the psoas muscle will be identified. A skin wheal will be made using lidocaine 1% at each level and then a 22-gauge Tuohy needle will be advanced inplane until it made contact with the transverse process. The needle will be withdrawn slightly and 30cc of bupivacaine 0.25 % (15ml for each side) will be injected slowly after negative aspiration was confirmed. The same procedure will be repeated in the contralateral side.
PROCEDURE	TAP block	a linear array transducer 5-12 MHz will be positioned inferior and parallel to the costal margin in a medio-lateral orientation. The external oblique, internal oblique and transverse abdominis muscles will be identified immediately lateral to the linea semilunaris. A a 22-gauge needle will be advanced medially and in-plane to the US beam until the tip lies between the fascia of the internal oblique muscle and the transverse abdominis muscle layers. 30 ml of 0.25 % bupivacaine will be injected in each side and the spread will be observed between the two muscles layers.
