Objective: This study aimed to investigate the effect of the continuous paravertebral block using either fentanyl or dexmedetomidine as an additive to bupivacaine in patients undergoing renal surgeries.
Methods: Ninety adult patients presented for renal surgeries under general anesthesia and ultrasound-guided continuous paravertebral block were allocated in this study and randomly distributed into three groups. All the patients received a loading and a maintenance doses of local anesthetic mixtures composed of bupivacaine alone in Control group with addition of fentanyl or dexmedetomidine in Fentanyl and Dexmedetomidine groups.
