Comparative Study on the Effect of Low Dose Dexmedetomidine and Clonidine as Adjuvant on the Quality of Subarachnoid Block by 0.5% Heavy Bupivacaine
Low-dose intrathecal dexmedetomidine provided superior block characteristics and longer postoperative analgesia than clonidine while maintaining stable hemodynamic and safety profiles and appears to be an effective adjuvant to hyperbaric bupivacaine with a comparable safety profile in subarachnoid anesthesia.
