Clinical Trial Summary

To compare external oblique intercostal block versus paravertebral block for post operative analgesia in patients undergoing laparoscopic cholecystectomy to decease post operative opioid consumption and use the least dose of local anesthesia.

Description:

Paravertebral Block (PVB) involve injection of local anesthetic in a space immediately lateral to where the spinal nerves emerge from the intervertebral foramina. This technique is being used increasingly for not only intra-operative and post-operative analgesia but also as a sole anesthetic technique for carrying out various procedures. This popularity is mainly due to the ease of the technique and fewer complications.

The external oblique intercostal block is a novel motor- and opioid-sparing technique which blocks both the anterior and lateral cutaneous branches of the thoracoabdominal nerves which innervate the upper abdominal quadrant.

Intervention

Procedure:
• The external oblique intercostal block
chest wall will be systematically scanned. Initially the probe will be placed in a cephalad to caudad paramedian direction at the anterior axillary line, and the external oblique muscle will be identified at the level ribs 6 and 7 in line with the xiphoid process to confirm correct identification of the external oblique muscle, the probe will be moved in the caudad direction following the external oblique muscle. At the subcostal level, the ultrasound probe will be rotated 90° to see the convergence with the internal oblique and transversus abdominus muscles. The probe will be then moved back to the initial identification point for the external oblique muscle. The EOI plane will be identified deep to the external oblique muscle and superficial to the sixth and seventh ribs and their associated intercostal muscles. Local anesthetic agent will be 20 ml volume (10 ml bupivacaine, 10 ml saline) will be injected under ultrasound guidance and this will be done bilaterally.
• Paravertebral block
involve injection of local anaesthetic in a space immediately lateral to where the spinal nerves emerge from the intervertebral foramina. This technique is being used increasingly for not only intra-operative and post-operative analgesia but also as a sole anaesthetic technique for carrying out various procedures.
