简要总结

Analgesia methods such as systemic analgesics, quadratus lumborum block, and transversus abdominis plane block are used for pain management after lower abdominal surgery. Quadratus lumborum block (QLB) requires the patient to be in the lateral decubitus position, and the drug injection point is deeper. Transversus abdominis plane (TAP) block, on the other hand, can be performed with the patient supine, and the drug injection point is more superficial. However, while TAP block has no effect on visceral pain, QLB is also effective in visceral pain. Furthermore, although the injection point for QLB is deep, systemic absorption of the drug is expected to be lower than with TAP block due to its distance from vascular structures. Consequently, blood local anesthetic concentrations and the risk of local anesthetic systemic toxicity (LAST) are also expected to be lower. Despite the deeper injection, it is expected to provide better analgesia and a lower risk of LAST, making it superior to TAP block. This study aimed to compare the postoperative pain relief effect of quadratus lumborum block and transversus abdominis plane block, routinely performed in the clinic to prevent postoperative pain in pediatric patients undergoing inguinal hernia surgery, using the FLACC (Face, Leg Mobility, Activity, Crying, and Consolability) score for blood bupivacaine dose after drug injection. Based on these data, if lower blood drug concentrations are detected in patients undergoing QLB, the investigators aim to implement this technique routinely in clinical practice.

研究组 & 干预措施

GROUP USING Transversus Abdominis Plane Block

Active Comparator

After induction of general anesthesia in all patients, once airway security is ensured, the standard regional anesthesia technique will be performed under ultrasound guidance by the same physician. A transversus abdominis plane block will be performed using an in-plane approach, passing through the external oblique and internal oblique muscles visible on ultrasound, and then advancing toward the fascial layer separating the internal oblique and transversus abdominis muscles. Following the block, the surgical team will begin the procedure. Thirty and sixty minutes after the block, 2 mL of blood will be collected into a routine biochemistry tube, and the blood bupivacaine level will be measured.

干预措施: Transversus Abdominis Plane Block (Procedure)

GROUP USING Quadratus Lumborum Block

Active Comparator

After induction of general anesthesia in all patients, once airway security is ensured, the standard regional anesthesia technique will be performed by the same person under ultrasound guidance. The ultrasound probe is placed transversely, just above the iliac crest in the midaxillary line. After visualizing the vertebral body, transverse process, psoas major, quadratus lumborum, and erector spinae muscles, a local anesthetic will be administered between the quadratus lumborum and psoas major muscles, using an in-plane approach, as visible on ultrasound. Thirty and 60 minutes after the block, 2 mL of blood will be collected in a routine biochemistry tube, and the blood bupivacaine level will be measured.
