Summary

the purpose of this study is to compare of better postoperative analgesia following laparoscopic cholecystectomy using either one puncture rectus sheath block with transverse abdominis plane block or multipoint technique

Conditions

  • Laparoscopic Cholecystectomy

Interventions

PROCEDURE

US-guided RSB and TAPB by one-puncture technique.

The probe will be positioned transversely in the midline of the abdomen, between the xiphoid process and the umbilicus, revealing the linea alba. It was then moved outward along the costal margin, demonstrating the rectus abdominis overlapping the transverse abdominis. A 22-gauge, 120-mm ultrasound-visible block needle will be inserted from the inner side . Under direct vision, we will reach the posterior rectus abdominis sheath and pierced the anterior layer of the posterior sheath. Saline was injected to adjust its position. After that, 15 mL of 0.25% bupivacaine will be administered (aspiration was performed for every 5 mL injection), and we will observe the local anesthetic spreading inward . Then, the needle will break through the posterior layer of the tendon, and saline will be injected to confirm the needle's placement in the transversus abdominis plane. After confirming the tip placement, 15 mL of 0.25% bupivacaine will be slowly injected. The needle tip will be advanced al

PROCEDURE

, the probe will be moved outward along the costal margin until the external oblique muscle, internal oblique muscle, and transverse abdominis muscle will be visible \[9\]. The needle will be inserted in-plane until the tip was positioned in the plane between the internal oblique muscle and the transverse abdominis muscle. Then, 15 mL of 0.25% bupivacaine will be injected . The contralateral nerve block will be performed using the same method and volume of anesthetic solution. For the RSB, the same technique will be done as one puncture technique. Then, 15 mL of 0.25% bupivacaine will be injected . The contralateral nerve block will be performed using the same method and volume of anesthetic solution.
