Official title

One-Puncture Versus Multipoint Technique of Rectus Sheath Block With Transverse Abdominis Plane Block for Analgesia After Laparoscopic Cholecystectomy

Overview

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

Detailed description

after being informed about the study and potential risks. All patients giving written consent will be randomized by double blind manner into 3 groups each one containing 34In the One puncture \"O\" group (n= 34): The patient will receive one-puncture technique of RSB combined with TAPB.

In the Multipoint \"M \" group (n= 34): The patient will receive multipoint technique of RSB combined with TAPB.

In the Control \"C \" group (n=34 ): The patient will receive patient controlled analgesia\&;PCA\&

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

    , 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
