Comparison of the effects of intrathecal bupivacaine, levobupivacaine and ropivacaine in lower abdominal surgery: a double-blind, randomized controlled trial using isobaric preparations
Background: Though various local anesthetic agents are widely used intrathecally for lower umbilical surgeries, their efficacy vary even when used in equipotent doses. Objective: The present study has been conducted to compare the efficacy of intrathecal bupivacaine, levobupivacaine and ropivacaine in lower umbilical surgery using isobaric preparations.
