Comparison of Spinal Anesthesia Adjuvant and Quadratus Lumborum Block on the Opioid Requirement and Perioperative Pain of Laparoscopic Kidney Transplant Donor

Patients in this arm will receive 10 mg 0.5% hyperbaric Bupivacaine, 100 mcg Morphine, 100 mcg Sulfas Atropine, and 0.9% normal saline to total volume of 4 ml before induction of anesthesia.

Patients in this arm will receive quadratus lumborum block with 20-30 ml of 0.25% Bupivacaine after induction of anesthesia and after operation.

The subject will undergo preoxygenation with 100% oxygen for 3 minutes. Following preoxygenation, anesthesia induction will be performed using lidocaine at a dose of 1.5 mg/kg, fentanyl at 1.5 mcg/kg, and propofol at 2.0 mg/kg. Once the subject is adequately sedated, baseline neuromuscular monitoring using the train-of-four (TOF) technique will be conducted, followed by the administration of rocuronium at a dose of 0.8 mg/kg. Endotracheal intubation will be performed using direct laryngoscopy once the TOF value reaches 0, utilizing an appropriately sized endotracheal tube (ETT). Ten milligrams of intravenous dexamethasone is administered after induction.
