Background Levobupivacaine is a relatively new amide local anesthetic, and it has been already investigated in epidural and locoregional techniques, but more has to be known regarding its characteristics in spinal anesthesia. Aims The aim of our study was to compare clinical and anesthetic features of levobupivacaine and racemic bupivacaine when intrathecally administered in patients undergoing elective Cesarean section. Patients and methods Hundred patients of ASA I and II were randomized to receive an intrathecal injection of one of two local anesthetic solutions. Each patient in group L (n = 50) received 2 ml of isobaric levobupivacaine 5 mg/ml (10 mg) with 15 μg of fentanyl, whereas each patient in group B (n = 50) received 2 ml of hyperbaric bupivacaine (10 mg) with 15 μg of fentanyl. The parameters studied were onset and total duration of sensory block, onset and total duration of motor block, the quality of intraoperative anesthesia, hemodynamic alterations, and any intraoperative and postoperative complications. Results There were no significant differences in demographic or surgical variables between the two groups. There was no significant difference in the quality of anesthesia and intraoperative side effects in the two groups. Time to complete regression of motor blockade was statistically lower in group L (135 ± 15.6 vs. 145 ± 20.5 min; P < 0.005) compared with group B. There were no significant differences in onset of sensory and motor block in the two groups. The total duration of sensory at T 12 level in group L (168.3 ± 15.6 vs. 172.2 ± 20.5 min; P > 0.005) was nonsignificant when compared with group B. Conclusion Levobupivacaine, the pure S (-) enantiomer of racemic bupivacaine, is an equally effective local anesthetic for spinal anesthesia for Cesarean section, compared with racemic bupivacaine.
