Brief summary

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.

Detailed description

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 .

Interventions

PROCEDUREPatients undergoing transversalis fascia plane block

The investigators applied a transversalis fascia plane block to the group of patients who had a cesarean section under spinal anesthesia to prevent postoperative pain.

PROCEDUREPatients undergoing transversus abdominis plane block

The investigators applied a transversus abdominis plane block to the group of patients who had a cesarean section under spinal anesthesia to prevent postoperative pain.

Design outcomes

Primary

MeasureTime frameDescription
time of first analgesic need24 hours postoperativelyOur primary goal was to meet the initial analgesic requirement times.

Secondary

MeasureTime frameDescription
visuel analog scale24 hours postoperativelyOur secondary aim was to compare postoperative pain scores. The first 24 hours postoperatively were evaluated.Visual analog scale(VAS) was used to assess postoperative pain.6th, 12th, 24th hour VAS values were recorded For example, 0-10 where 0 is no pain and 10 is the worst pain imaginable.
