Comparing Quadratus Lumborum Type 1 Block to The Combination Of Intraperitoneal Instillation Of Local Anesthetics And Wound Infiltration For Postoperative Pain After Cesarean Delivery: A Prospective Double-Blind Randomized Controlled Study

the surgeon will be given a solution containing 20 ml of 0.5% bupivacaine, 20 ml of 2% lidocaine and 1:200,000 epinephrine with a total volume of 40 ml. A volume of 10 millilitres of the solution will be administered through the drip technique into each of the four quadrants of the uterus prior to the subsequent closure of the parietal peritoneum or fascia. A total volume of 10 ml of the solution will be administered through infiltration at the edges of the rectus aponeurosis, while the remaining 20 ml will be infiltrated subcutaneously into the incision. Patients will receive 800mg of ibuprofen and 1g of paracetamol 30 minutes prior to the end of the procedure. Following the surgical procedure, each patient will get a dosage of 15 mg/kg paracetamol every 6 hours and 800 mg of ibuprofen every 8 hours for 24 hours.

In the QLB group, quadratus lumborum type 1 block will be applied bilaterally on both sides with a total of 40 ml of solution containing 20 ml of 0.5% bupivacaine + 20 ml of 2% lidocaine + 1:200.000 epinephrine, under ultrasound guidance. Patients will receive 800mg of ibuprofen and 1g of paracetamol 30 minutes prior to the end of the procedure. Following the surgical procedure, each patient will get a dosage of 15 mg/kg paracetamol every 6 hours and 800 mg of ibuprofen every 8 hours for 24 hours.
