Background: Neuraxial anaesthesia greatly expand the anaesthesiologist armamentarium in many cases providing alternative to general anaesthesia. Spinal anaesthesia is a popular technique for lower limb orthopaedic surgeries. Hyperbaric bupivacaine in 8% glucose is often used. Unintended intravascular injection of bupivacaine during regional anaesthesia may cause severe cardiovascular toxicity, including left ventricular depression,atrioventricular heart block,life threatnig ventricular tachycardia, fibrillation and sudden cardiac arrest which is difficult to resuscitate However levobupivacaine has similar efficacy but better safety profile than racemic bupivacaine.
