One-Puncture Versus Multipoint Technique of Rectus Sheath Block with Transverse Abdominis Plane Block

Not Applicable

• Conditions: Laparoscopic Cholecystectomy
• Interventions: Procedure: US-guided RSB and TAPB by one-puncture technique.; Procedure: multipont

• Registration Number: NCT06599255
• Lead Sponsor: Zagazig University

Brief 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

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\&
