Background: Combination of Local anaesthetics for epidural anaesthesia will improve block characteristics and reduce toxicity. Previous studies have shown lidocaine to shorten onset time while bupivacaine prolongs duration of anaesthesia.
Objective: The aim of this study was to comparatively evaluate the block characteristics of epidural injection of different lidocaine-bupivacaine mixtures for lower limb surgeries.
Methods: Sixty-three patients receive either 15 ml of 0.5% Isobaric-bupivacaine and 5 ml of 2% Lidocaine (group A), or 15 ml of 0.5% Isobaric-bupivacaine, 2.5 ml of 2% Lidocaine and 2.5 ml normal saline (group B) or 15 ml of 0.5% Isobaric-bupivacaine and 5 ml of normal saline (group C). The primary outcome was the onset time of sensory block. The secondary outcomes were the onset of motor blockade, degree o.. View More»
