Abstract

Background: The frequent presentation of postoperative pain constitutes a significant clinical concern, especially after cesarean deliveries. Effective management is crucial to avoid negative consequences. This study aimed to improve postoperative pain management after cesarean delivery by assessing the effectiveness of ultrasound guided transversalis fascia plane block in comparison to transversus abdominis plane block.
Methods: This prospective, randomized investigation recruited 74 pregnant patients, aged 20-40 years. They were assigned randomly to either transversalis fascia plane block (TFPB) group or transversus abdominis plane block (TAPB) group, each receiving 20 ml of 0.25% bupivacaine on each side.
Results: The mean visual analogue scale was significantly lower among the TFPB group than the TAPB group (P value < 0.001). The time for first morphine request was significantly delayed among the TFPB group than the other group (12.7 ± 2.2 vs 10.2 ± 2.1, respectively with a p value <0.001). The total morphine dose required in the TFPB group was 2.9 ± 0.8 and in the TAPB group was 3.8 ± 1.5 (P value <0.001).
Conclusions: The TFPB provided longer pain relief, delaying the need for additional analgesics compared to the TAPB, highlighting its superior effect in postoperative pain management.
