Caudal Block and Transversus Abdominis Plane Block in Pediatric Inguinal Hernia Repair

Regional Anesthesia Clinical Trial

Official title: Effects Of Ultrasound Guided Caudal Epidural And Transversus Abdominis Plane Block On Postoperative Analgesia In Pediatric Inguinal Hernia Repair Surgeries

Status Completed

Clinical Trial Summary

Pediatric inguinal hernia repair (IHR) candidates experiences ordinarily mild to moderate pain, rarely severe pain in the postoperative period. Caudal epidural block (CEB) and transversus abdominis plane block (TAPB) are two effective postoperative analgesia options. In this randomized study, it is aimed to compare the effects of CEB and TAPB on postoperative pain scores, additional analgesic requirement, postoperative nausea and vomiting incidence, procedural complications, family and surgeon satisfaction, length of hospital stay, chronic pain development in pediatric bilateral open IHR.

Clinical Trial Description

Inguinal hernia repair (IHR) is the second common operation in pediatric surgery practice following appendectomy and bilateral repair is needed in 10.9% of the cases due to presence of contralateral inguinal hernia. After IHR, the children generally experiences mild to moderate pain, and occasional severe pain. For pediatric population the prevalence of chronic pain after IHR is 5% which is a solid cause for severe pain. Adequate pain control is a crucial part of perioperative management to reduce morbidity and ensure family and patient satisfaction especially after pediatric surgeries. Although there are substantial studies to show how to assess and manage the postoperative pain in children, the pain control is often not achieved. Several analgesic regimens including systemic medications and/or regional analgesia methods may be preferred by clinicians. As previous studies revealed; best combination for pain management after pediatric IHR is still obscure. Caudal epidural block (CEB) and transversus abdominis plane block (TAPB) are the two regional analgesia methods which may be chosen for multimodal analgesia. CEB is accepted as gold standard for lower abdominal surgeries in children which diminishes somatic and visceral pain with a duration of 6 hours. TAPB is another regional analgesia method which covers only somatic pain up to 24 hours postoperatively with lower complication rates compared to CEB. The results of clinical studies examining the effects of CEB and TAPB on early postoperative pain after pediatric IHR are conflicting. Currently, the effects of these blocks on the incidence of chronic pain after pediatric IHR is not well-investigated in the literature. As a matter of fact, there are no recommendations for bilateral IHR in pediatric postoperative pain guidelines, despite these surgical procedures being an independent risk factor for severe pain. In this randomized study, it is aimed to compare the effects of ultrasound (US) guided CEB and TAPB on postoperative analgesia. Our hypothesis was that bilateral TAPB block will be equally effective as CEB in the early postoperative period and the analgesic duration will be longer than CEB. Our primary outcome was FLACC (face, legs, activity, cry, consolability) scores in postoperative 24 hours. The secondary outcomes included additional analgesic requirements, postoperative nausea vomiting incidence, procedural complications, length of hospital stay, family and surgeon satisfaction and chronic pain development at the postoperative 2nd month. ;
