The goal of this prospective randomized study was to compare the efficacy of transversus abdominis plane block and transversalis fascia plane block for postoperative analgesia in patients undergoing elective cesarean section under spinal anesthesia.

The main question[s] it aims to answer are:

[Is transversalis fascia plane block more effective in postoperative analgesia? ]

[Is there a difference between the duration of postoperative first analgesia requirement? ] Since the pain scores after the block at the end of the operation will be evaluated during the postoperative 24 hours, the participants will be asked to give a value between 0 and 10 in certain time periods.

This prospective, randomized trial was conducted at Başakşehir Çam and Sakura City Hospital by the Declaration of Helsinki. After ethics committee approval (decision no: 2022-74, date: 09.03.2022) and written informed consent was obtained from all patients, the trial was conduct-ed according to Consolidated Standards of Reporting Trials (CONSORT) guidelines.A total of 150 patients were divided into two groups: transversal fascia plane block (TFPB group) and Transversus abdominis plane block (TAPB group).VAS values, time to first analgesic requirement, analgesic requirements, nausea & vomiting and pruritus were evaluated for 24 hours postoperatively (6th hour (T2), 12th hour (T3), 24th hour .
