Regional anesthesia and analgesia techniques are frequently used to provide pain control in pediatric surgical applications. The main advantages of these techniques include ease of application, good analgesic efficacy and low risk of complications (1). It reduces the need for parenteral opioids and increases the quality of postoperative pain control and the satisfaction of the patient and family (2). The aim of this study was to compare the contribution of TAP block and ESP block combined with sedation in pediatric surgery to anesthesia and analgesia during surgery without general anesthesia.
