Summary

This current comparative study involved 54 patients undergoing thoracoscopic thymectomy who were distributed randomly into three equal groups to receive ultrasound (US)-guided ESPB using 20 ml bupivacaine 0.25% (group B) , 20 ml bupivacaine 0.25% with 8 mg dexamethasone (group BS), 20 ml bupivacaine 0.25% with dexmedetomidine 1mcg/kg (group BM). The time till the first postoperative rescue analgesic requested was the primary outcome. The secondary outcomes included the postoperative pain scores and analgesic consumption.

Conditions

  • Postoperative Pain, Acute

Interventions

PROCEDURE

Erector Spinae Plane Block

An echogenic 21 gauge 10 cm needle was introduced in caudo-cephalic orientation utilizing the in-plane approach and traversing through trapezius, rhomboid, and erector spinae muscles till reaching the transverse process then slightly withdrawn and hydrodissection was done by 3 mL of saline 0.9% to verify the accurate implantation of the block needle tip between the erector spinae muscle and the transverse process (the erector spinae plane). Incremental LA injection was verified through US observation for the upward displacement and lifting of erector spinae muscle from the transverse process with craniocaudal spread of the LA in the targeted plane. The LA increments were one ml every 5 seconds with intermittent aspiration every 5 mL to avoid intravascular injection.
