Sufentanil (SUF) and dexmedetomidine (DEX) are used as bupivacaine in the spinal technique that providing stable hemodynamic conditions with least side effects. This study aimed to compare the change in saturation oxygen and hemodynamic responses after intrathecal DEX and SUF as adjuvants to bupivacaine in patients undergoing dynamic hip screw. This clinical trial was conducted with 80 patients referring to Valiasr Hospital, Arak, Iran, who were randomly assigned to two groups (n = 40): DEX group (8 mg bupivacaine with 5 μg DEX) and SUF group (8 mg bupivacaine with 2.5 μg SUF). The pain severity was lower in DEX group at different hours and the systolic pressure and diastolic blood pressure were lower in DEX group than in SUF group after surgery. Saturation oxygen was generally lower and more stable in DEX group but there was no significant difference between two groups. The incidence of sensory and motor block was lower in DEX group than in SUF group, but the duration of assessment of sensory block was lower in SUF group than in DEX group. DEX relieves pain up to 24 hours postoperatively. Nevertheless, Care should be taken to avoid the DEX induced shivering in patients. The study was approved by Ethical Committee of Arak University of Medical Sciences by IR.ARAKMU.REC.1395.32 code on April 25, 2016 and was registered in Iranian Registry of Clinical Trials by code number: IRCT2017050220258N45 on August 4, 2017.
