Evaluation of adding clonidine to lignocaine during bier’s block in upper limb surgeries
Journal Title: Medpulse International Journal of Anesthesiology - Year 2017, Vol 8, Issue 1
Abstract
Background and aims: Bier’s block a.k.a Intravenous regional anaesthesia (IVRA) is used for short duration procedures for limb surgeries. IVRA provides reliable analgesia with good muscular relaxation of the extremity distal to the tourniquet, but tourniquet pain and absence of post-operative analgesia are the major drawbacks. In this study, the efficacy of adding clonidine as an adjuvant to IVRA for upper limb surgeries, was evaluated with respect to block characteristics, tourniquet pain and post-operative analgesia. Methods: A prospective, randomised, double-blind study was conducted on 60 adult patients of American Society of Anaesthesiologists grade 1 and 2, undergoing short duration upper limb surgeries. Patients were randomised into two groups of 30 each. One group received 40 ml of 0.5% preservative-free plain lignocaine and other group received clonidine 1µg/kg added to 40 ml of 0.5% plain lignocaine. Results: Sensory recovery time, sedation score and duration of post - op analgesia were significantly increased in clonidine group (p < 0.05). Sensorimotor block onset, motor recovery time and need for rescue analgesia were comparable in both the groups. Haemodynamic parameters were comparable. Conclusions: Clonidine significantly increased post-operative analgesia and sensory recovery time but it did not prevent tourniquet pain. Sedation scores were higher in clonidine group.
