Comparison in Hemodynamic Effect Of Intrathercal Ropivacaine Heavy (0.75%) Vs Bupivacaine Heavy (0.5%) In Lower Limb Surgeries

Abstract

Background: Spinal anesthesia is the most popular regional anesthesia technique for 
lower limb and lower abdominal surgery. Bupivacaine 0.5% heavy is commonly used for 
intrathecal use. New long-acting local anesthetic agents such as ropivacaine have claimed benefits 
of reduced cardiac toxicity on overdose and more specific effects on sensory rather than motor 
nerve fibers. The use of intrathecal hyperbaric ropivacaine is not much studied. With this 
background, we studied intrathecal ropivacaine hyperbaric 0.75% against intrathecal bupivacaine 
hyperbaric 0.5% for lower abdominal and lower limb surgery
