Abstract

The aim of this study was to determine the analgesic and systemyc effects of a low dose clonidine added to prilocaine in brachial plexus blockade. We studied 40 ASA I-II class patients in two equal groups who were scheduled for elective upper arm surgery. Brachial plexus block was performed with 30 mL of 1.5 % prilocaine in Group 1 and 75 μg clonidine was added to same solution in Group II. We monitored heart rate (HR), systolic and diastolic arterial blood pressure (SBP, DBP) and peripheral O2 saturation (SpO2) throughout the study. We recorded HR, SBP, DBP and sedation scores at 0, 10, 20, 30, 60, 120. minutes. Onset of action and duration of sensory and motor blockade, adverse effects and complications were recorded. Onset of motor and sensory block in radial, median and ulnar nerve were not different between the groups. Duration of motor and sensory block in radial and median nerve were more extended in Group II but there were no difference in ulnar nerve. This study suggests that, adding 1 μg/kg clonidine to prilocaine in brachial plexus blockade increases the duration of the block.
