Comparative Efficacy of Dexmedetomidine as an Adjuvant to Intrathecal Hyperbaric Levobupivacaine versus Ropivacaine in Spinal Anaesthesia: A Randomized Controlled Trial

Background and Aims: The selection of optimal local anaesthetic and adjuvant combinations in spinal anaesthesia significantly influences clinical outcomes, particularly regarding block characteristics, hemodynamic stability, and postoperative analgesia. The objective of our study was to compare the efficacy and safety of dexmedetomidine as an adjuvant to intrathecal hyperbaric levobupivacaine versus ropivacaine in adult patients undergoing elective surgery.
