The Effects of Clonidine with Bupivacaine in Spinal Anaesthesia to Lower Limb Orthopaedic Surgery Cases: A Retrospective Cohort Study

Neuroaxial Anaesthesia is safe for lower limb orthopaedic surgeries. But duration of sensory and motor block dose not beyond 3 hours with local anaesthetic alone. For prolongation of regional anaesthesia, adjuvants are added to local anaesthetic agents. Clonidine is a frequently used adjuvant to local anaesthetics. Objectives: (1) This study was under taken to assess onset and duration of sensory and motor block. (2) Intra and post operative pain and adverse effects. Study Design: It is retrospective study.
