TRIAL DESCRIPTION
Public title Ultrasound-Guided Erector Spinae Plane Block Versus External Oblique Intercostal Plane Block in Patients Undergoing Laparoscopic Cholecystectomy
Official scientific title Analgesic Effect of Ultrasound-Guided Erector Spinae Plane Block Versus External Oblique Intercostal Plane Block in Patients Undergoing Laparoscopic Cholecystectomy: A Randomized Controlled Trial
Brief summary describing the background and objectives of the trial The External oblique intercostal plane (EOI) block is a recent described technique for upper midline and lateral abdominal wall analgesia. Elsharkawy et al. demonstrated the potential mechanism of this technique with a cadaveric study reporting consistent staining of both lateral and anterior branches of intercostal nerves T7-T10 aim :evaluate the analgesic effect of bilateral erector spinae plane block versus bilateral external oblique intercostal plane block in patients undergoing Laparoscopic Cholecystectomy ,opioid consumption and haemodynamic changes.

Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group erector spine block ESP g. A volume of 20 mL of Local Anesthetic mixture (10 mL of bupivacaine 0.5%, 1 mL of dexamethasone and 9 mL of normal saline to make a mixture totaling 20 ml.) will be injected. once after induction While the patient is in lateral position and after disinfecting the skin, a high-frequency linear ultrasound probe will be placed in a longitudinal 9 parasagittal orientation 2.5-3 cm lateral to the T9 spinous process. The erector spinae muscles will be identified superficial to the tip of the T9 transverse process. A 22-G, 10 cm needle will be inserted using an in plane approach. The tip of the needle will be placed into the fascial plane on the deep aspect of the erector spinae muscl 31
Experimental Group External oblique intercostal block 20 mL of LA mixture (10 mL of bupivacaine 0.5%, 1 mL of dexamethasone and 9 mL of normal saline to make a mixture totaling 20 ml.) will be injected. T once preoperative high-frequency linear ultrasound probe will be placed in a longitudinal parasagittal orientation at the sixth intercostal space in the anterior midaxillary line. A 22-G, 10 cm needle will be inserted using an in plane approach. The tip of the needle will be placed into the fascial plane on the deep aspect of the external oblique musc 31

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome To assess the analgesic effect of different modalities of analgesia (ESP block, EOI block and conventional fentanyl analgesia) in patients scheduled for laparoscopic cholecystectomy regarding the first request for analgesia Time for the first request for rescue analgesia ,Postoperative after patient transportation and stabilization in ward and after 2,6,12,18 and 24 hours in the ward.
Secondary Outcome 1. Postoperative pain severity as evaluated by Numerical Rating scale (NRS). 2. Postoperative consumption of additional opioids within the first 24 hours after surgery. 3. Hemodynamic variables (HR and MAP). 4. Incidence of postoperative nausea and vomiting (PONV). 5. Shoulder pain. Time for the first request for rescue analgesia ,Postoperative after patient transportation and stabilization in ward and after 2,6,12,18 and 24 hours in the ward.
