Abstract
- Aims: The aim of the present study is to substantiate and compare the quality and extent of nerve block by using intrathecal bupivacaine or extradural bupivacaine alone and in combined spinal-epidural (CSE) technique using smaller dose of intrathecal bupivacaine and extradural injection of a smaller dose of bupivacaine or normal saline.<br />Setting and Design: A prospective study design was set up with 60 adult patients scheduled for vaginal and lower abdominal operation under CSE technique and single spinal or epidural technique.<br />Materials and Methods: 60 patients undergoing infra-umbilical surgery were divided into three groups (Group). Group A1 (control) 10 patients received 3 ml of intrathecal heavy bupivacaine. A2-10 patients received 16 ml isobaric bupivacaine extradurally Group B (n = 20) patients received 2 ml intrathecal heavy bupivacaine and 10 ml normal saline extradurally. Group C patients (n = 20) received 2 ml heavy bupivacaine intrathecally and 10 ml isobaric bupivacaine extradurally. A total duration of this study was 18 months. Duration of motor block, sensory block, analgesia, onset of sensory block and cephaloid extent of sensory block and side-effects noted among patients. Visual analog scale in the post-operative period was recorded.<br />Statistical Analysis: The results were analyzed statistically by applying analysis of variable, odds ratio and Chi-square test.<br />Results: Patients were comparable regarding the onset time and height and duration of sensory block with a significant difference, though there was no difference in duration of motor block and analgesia. The side-effects in the control group are higher than the other two groups.<br />Conclusion: Quality of nerve block in combined technique using bupivacaine both intrathecally and extradurally is better and associated with lower side-effect compared with intrathecal heavy bupivacaine or extradural isobaric bupivacaine alone.
