Comparing Analgesic Effects of Caudal and Erector Spinae Plane Blocks in Pediatrics Undergoing Upper Abdominal Surgery

Overview

Upper abdominal surgeries are painful and pediatric patients who undergo these operations require effective postoperative pain control. Epidural and caudal blocks are considered to be the gold standard regional analgesia techniques. Currently, ultrasound guidance is commonly used for caudal block performances to demonstrate the cannula placement and the deposition of local anesthetic. Additionally, erector spinae plane block can be a safer alternative for blocking the similar dermatomes. In this study, the aim is to compare postoperative analgesic effects of these two ultrasound-guided techniques in pediatric patients. The primary outcome of this study is the follow-up of FLACC/VAS pain scores. Secondary outcomes are time to first analgesic requirement, number of patients who require rescue analgesic, possible side effects, time to first mobilization, length of hospital stay and chronic pain due to incision after 2 months.

Upper abdominal surgeries are painful and pediatric patients who undergo these operations require effective postoperative pain control. Blockade of dermatomes between T6 and L1 commonly provides effective postoperative analgesia. Epidural and caudal blocks are considered to be the gold standard regional analgesia techniques as they provide both somatic and visceral analgesia. Currently, ultrasound guidance is commonly used for caudal block performances to demonstrate the cannula placement and the deposition of local anesthetic. Additionally, erector spinae plane block can be a safer alternative for blocking the similar dermatomes. In the present study, the aim is to compare postoperative analgesic effects of these two ultrasound-guided techniques in pediatric patients undergoing upper abdominal surgery. The primary outcome of this study is the follow-up of FLACC/VAS pain scores. Secondary outcomes are time to first analgesic requirement, number of patients who require rescue analgesic, possible side effects (nausea, vomiting, itching, urinary retention, bradycardia, hypotension, respiratory depression), time to first mobilization, length of hospital stay and chronic pain due to incision after 2 months.
