External Oblique Intercostal Block Versus Paravertebral Block for Postoperative Analgesia in Laparoscopic Cholecystectomy Patients

External Oblique Intercostal Block Versus Paravertebral Block for Postoperative Analgesia in Laparoscopic Cholecystectomy Patients

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.

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.
