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).
