In order To investigate the effect of addition of clonidine to lidocaine on duration of spinal analgesia and need for postoperative analgesics after Caesarean section delivery, this randomized case-controlled double-blind clinical trial was designed and conducted. 166 eligible women were randomly allocated to either case or control group (n=83), Spinal anesthesia was done by 75-100 mg lidocaine 0.5% in control group and by 75-100 mg lidocaine 0.5% plus 75μg clonidine in case group. Onset of analgesia, Blood pressure, Hypotension, Bradycardia, and Neonates Apgar scores were recorded during surgery. After surgery, duration of sensory and motor functions, Intensity of post-operative nausea and vomiting, Total analgesic consumption and time to first analgesic request were assessed. Data were analyzed by SPSS and an alpha level < 0.05 was considered to be statistically significant. Onset of analgesia, Duration of Motor and sensory block, mothers’ systolic blood pressure and pulse rate in different recorded times, and Total Analgesic consumption in case group showed a statically significant difference in comparison to the control group. Analgesia demanding, Time of first request for analgesics, Intensity of Nauseas and vomiting, Apgar score showed no significant difference. We have demonstrated that addition of 75 μg clonidine to lidocaine extends spinal analgesia along with sensory and motor block after Caesarean section and improves early analgesia without clinically significant maternal or neonatal side-effects. This single 75 μg intrathecal clonidine dose also reduced the amount of subsequent analgesic consumption during the first 12 hours after delivery.
