35 Patients, ASA I and II, scheduled for arthroscopic surgery were included in this study to investigate the effects of intramuscular (IM) or oral clonidine premedication on lidocaine spinal anaesthesia sensorial block time and postoperative analgesic requirements. Premedication wasn't applied in group I (n = 10). In group II (n = 12) oral and in group III (n = 137) IM 150 mcg clonidine was applied 90 minutes before the operation. All patients received spinal anesthesia with 3.5 ml of 2% lidocaine. The highest sensory level and time from the injection to the highest sensory level, time for regression two and four segments and to L1 level were evaluated by Pinprick test 45th and 90th minutes sedation scores and the postoperative analgesic requirement were recorded. There were no differences in maximal level amount between the 3 groups (p > 0.05). Time for regression of two and four segments and to L1 were significantly longer in groups II and III (p < 0.01). According to these parameters there is no difference between groups I and III (p > 0.05). According to sedation there were significant differences between I and III in the 45th minutes, between groups I and II in the 90th minutes and between groups II and III in 45th and 90th minutes (p < 0.05). According to the postoperative analgesic requirement there was considerable difference between groups I-II and III (p < 0.05), but there was no difference between groups II and III (p > 0.05). As a result we decided that 150 mcg oral or IM clonidine which was given 90 minutes before the spinal anesthesia prolonged sensory block of lidocaine spinal anesthesia and postoperative analgesic requirements at the same ratio.
