This study aimed to compare the efficacy of local anaesthetic infiltration into all layers of the anterior abdominal wall with peritoneal instillation and QLB type I for pain reduction in women undergoing elective cesarean section under spinal anaesthesia.
This study will be conducted as a prospective randomized, controlled, double-blind trial following the approval of the ethical committee at Atatürk University Medical Faculty Hospital and after obtaining written consent from the participating patients. The study will include pregnant women aged 18 to 50 with American Society of Anesthesiologists (ASA) II classification, full-term and singleton pregnancies planned to undergo cesarean section using Pfannenstiel incision with spinal anaesthesia. Using a randomisation procedure, the participants will be allocated into two equal groups: Group IPLA+ LWI and Group QLB.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group Wound infiltration + Intraperitoneal local anaesthetic instillation | Active Comparator | 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. |

| Group QUADRATUS LUMBORUM BLOCK | Active Comparator | 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. |
