Spinal Anaesthesia With Levobupivacaine 0.5% and Ropivacaine 0.75% for Lower Limb Orthopaedic Surgery

A Comparative Study Between Levobupivacaine 0.5% and Ropivacaine 0.75% in Patients Undergoing Spinal Anaesthesia for Lower Limb Orthopaedic Surgery.

The purpose of this study is to compare the effects of two intrathecally administered drugs:0.5% levobupivacaine and0.75%Ropivacaine in spinal anesthesia

Bupivacaine is a highly cardiotoxic drug and also produces prolonged motor blockade.The newer drugs levobupivacaine and ropivacaine being comparatively less cardio and neurotoxic are preferred now a days.So, we conducted this prospective, randomized double blind study with an aim of comparing the efficacy and characteristics of these drugs.
