Comparison between Clinical Efficacies of Levobupivacaine Plain and Levobupivacaine with Fentanyl for Urological Surgeries under Subarachnoid Block

Abstract

ABSTRACTBackground and aimsSpinal anesthesia for urological operations has been frequently used, because symptoms of overhydration, transurethral resection of prostate (TURP) syndrome, and bladder perforation can be recognized. This prospective randomized study was conducted to compare the clinical efficacies of levobupivacaine with and without fentanyl in subarachnoid block with respect to onset and duration of sensory and motor block and duration of analgesia in urological surgeries.Materials and methodsThis randomized study was conducted in 100 patients of American Society of Anesthesiologists (ASA) physical status grades I and II, posted for urological surgeries. Patients were randomly allocated to two groups and were given the following drugs intrathecally as per group distribution: Group I: 2.5 mL of 0.5% isobaric levobupivacaine and group II: 2.2 mL of 0.5% isobaric levobupivacaine with 15 μg (0.3 mL) fentanyl citrate. Parameters monitored were onset and duration of sensory and motor block, hemodynamic parameters, postoperative analgesia, and side effects. Data were analyzed using Student's t-test for the continuous variables and chi-square test for categorical variables.ResultsThe onset of sensory level of T10 was earlier in group II (4.74 ± 0.723 minutes) than in group I (5.7 ± 0.953 minutes). Duration of sensory block was longer in group I (292.2 ± 8.154 minutes) than in group II (260 ± 11.066 minutes). Motor block regressed earlier in group II (181.2 ± 7.73 minutes) than in group I. Hemodynamic parameters and side effects were similar in both the groups.ConclusionFrom our study, we concluded that plain levobupivacaine provided a longer duration of sensory and motor subarachnoid blockade. However, addition of fentanyl as a spinal adjuvant had a dose-sparing effect with earlier onset and early regression of motor block and no hemodynamic alterations.How to cite this articleKulkarni A, Dey P.
