Levobupivacaine versus bupivacaine in epidural anesthesia for cesarean section. Comparative study.

Background And Objectives: Local anesthetic bupivacaine is found in two different enantiomers: levobupivacaine - S (-) and dextrobupivacaine - R (+). Based on studies showing that S(-) enantiomers are less cardiotoxic, their use has been increasing in clinical practice. This study aimed at comparing racemic bupivacaine and levobupivacaine in epidural anesthesia for elective cesarean section.
