Quality of Recovery in Laparoscopic Sleeve Gastrectomy Using Dexmedetomidine Infusion Versus Laparoscopic TAP Block in Combination With Paragastric Neural Block
Sponsor: Alexandria University
Summary
The goal of this clinical trial is to learn which is better, combining Dexmedetomidine infusion and paragastric neural block or combining laparoscopic TAP block and paragastric neural block to enhance recovery after laparoscopic sleeve gastrectomy. The main questions it aims to answer are: Will using paragastric neural block (PGNB) combined with dexmedetomidine infusion give better recovery or using PGNB combined with laparoscopic transversus abdominis plane (LTAP) block in patients undergoing laparoscopic sleeve gastrectomy. This will be assessed by: Recording how much opioids were consumed by the patients Hemodynamic stability of the enrolled patients Pain scores as given by the patient The quality of postoperative patient recovery How many patients encountered nausea or vomiting

Conditions
Interventions
Dexmedetomidine infusion
Dexmedetomidine will be maintained at 0.5 μg/kg/h ideal body weight via a syringe pump until trocar removal.
Paragastric neural block
Paragastric neural block (PGNB) will be administered using a 25-gauge needle attached to a venous catheter extension, introduced through the left 12 mm port. Infiltration of 20 mL undiluted 0.5% bupivacaine will be performed at six levels in the fatty tissue of the paragastric area, including the lesser omentum, vagus nerve, esophago-gastric junction, proximal stomach, mid-stomach, distal antrum, hepatic artery, and left gastric artery, with the needle cap removed under direct vision throughout the procedure.
Laparoscopic Transversus Abdominis Plane (LTAP) block
LTAP will be administered after insufflation before insertion of the right and left-handed ports. 30 mL of 0.25% bupivacaine will be injected into the posterolateral subcostal regions on both sides. The correct placement will be confirmed by observing the spread of fluid between the transversus abdominis and the internal oblique muscle layers laparoscopically
