OBJECTIVE: The objective of this study was to compare the analgesic efficacy of dexamethasone versus dexmedetomidine added to lidocaine using infraclavicular block in patients undergoing forearm fracture surgery.
METHOD: Seventy-five patients aged 20 to 60 years were recruited for a prospective, double-blinded, randomized clinical trial. Ultrasound-guided infraclavicular brachial plexus block was performed in 3 groups by injecting 28 mL lidocaine plus 2 mL distilled water (Lido), 28 mL lidocaine plus 2 mL (8 mg) dexamethasone (Dexa), and 28 mL lidocaine plus 2 mL (1 µg/kg) dexmedetomidine (Dexm). Sensory and motor block onset time and the duration, hemodynamic variables, the time for the first analgesic request, and the total analgesic agents consumed within 6 hours after infraclavicular block were assessed.
RESULTS: Sensory block duration in the Dexm group was significantly greater than in the Lido (P=0.019) and Dexa (P=0.046) groups. The mean motor block duration in the Dexm group showed to be significantly longer than that in the Lido group (P=0.009). Pain intensity within 4 hours after block significantly increased in the Lido group compared with that in the Dexa and Dexm groups (P=0.001). Analgesic consumption during 6 hours after the procedure was higher in the Lido group when compared with the other 2 groups (P=0.001). The Dexm group showed the highest reduction in the mean arterial pressure (P=0.006) and heart rate (P=0.001) among the 3 groups.
CONCLUSIONS: There was no significant difference in postoperative pain intensity between the Dexa and Dexm groups, although DEXm demonstrated a longer sensory block duration in comparison with dexamethasone as a lidocaine adjuvant in infraclavicular block.
