Evaluation of the Effectiveness of Transversus Abdominis Plane Block and Transversalis Fascia Plane Block in Postoperative Analgesia in Pediatric Patients Undergoing Lower Abdominal and Genitourinary Surgery: A Retrospective Study

Objective: Peripheral trunk blocks are used for multimodal analgesia in pediatric ambulatory surgery. In this study, we aimed to evaluate the efficacy of transversus abdominis plane block (TAPB) and transversalis fascia plane block (TFPB) for postoperative acute analgesia in lower abdominal and urogenital surgeries in pediatric patients.Methods: In our study, patients aged 3-16 years, American Society of Anesthesiology I-III, who underwent lower abdominal-urogenital surgery and peripheral trunk blocks for postoperative analgesia were retrospectively reviewed. Pain scores in the first 6 hours (h) postoperatively, additional analgesia needs of patients, and complications were evaluated.Results: Ninety-five patients who underwent TAPB and transversalis fascia plane block were evaluated. There was no statistically significant difference between the demographic data and operation time. The number of patients with a pain score >4 in the first 6 h was higher in the TAPB group (p<0.05). The additional analgesic requirement was lower in the TFPB group (p<0.05). There were no postoperative complications in either group.Conclusion: Peripheral trunk blocks can be used as a part of multimodal analgesia for early postoperative discharge in pediatric surgeries.
