Comparison of the Effects of TFPB and Anterior QLB on Postoperative Analgesia in Cesarean Section Surgery

Comparison of the Effects of Transversalis Fascia Plane Block and Anterior QLB ( TFPB and Anterior QLB ) on Postoperative Analgesia in Cesarean Section Surgery

This study evaluates the postoperative analgesic effects of transversalis fascia plane block and anterior quadratus lumborum block in patients having cesarean section under general anesthesia. General anesthesia will be performed to all patients for the surgery.

In this study, patients are divided into two groups. After the general anesthesia is performed and cesarean section surgery is over; TFPB block will be performed to patients in Group A ; while anterior QLB block will be performed to patients in Group B. In addition, patient controlled analgesia (PCA) will be used in the first 24 hours postoperatively. Group A - Patients in group A will have TFPB block after the surgery. In addition, patient controlled analgesia (PCA) will be used in the first 24 hours postoperatively. Group B - Patients in group B will have anterior QLB block after the surgery. In addition, patient controlled analgesia (PCA) will be used in the first 24 hours postoperatively.
