Comparison between efficacy of intrathecal 1% 2-Chloroprocaine VS intrathecal 0.5% Bupivacaine with General anaesthesia for short duration laparoscopic surgeries

Abstract

Background: The ideal anesthetic technique for laparoscopic surgery should maintain stable cardiovascular and respiratory functions, provide rapid postoperative recovery, lead to minimal postoperative nausea and vomiting and provide good postoperative pain relief for early mobility. Administering subarachnoid blocks before general anesthesia in laparoscopic surgeries offer the benefits of good surgery field, hemodynamic stability and reduced requirement of general anesthesia. When subarachnoid block is utilised for short duration laparoscopic surgeries, sympathectomy counteracts the increased systemic vascular resistance (due to pneumoperitoneum) and it contracts the bowel, thereby giving a better field to the surgeon. Methodology: In this study, 60 patients, aged 18-60 years belonging to ASA class I and II were taken and randomly allocated in 2 groups of 30 each. Group A (30 patients) given intrathecal 1% 2- chloroprocaine 30mg(3ml) combined with General anesthesia and Group B (30 patients) given intrathecal 0.5% bupivacaine 15mg (3ml) combined with General anesthesia. Result: The study revealed there is significant difference (p value 0.05) between both the groups with respect to hemodynamic parameters. Conclusion: Recovery from sensory motor blockade was faster with 1% 2-chloroprocaine thereby enabling surgeons to perform short duration laparoscopic surgeries on a day-care basis and hence minimising hospital stay. We recommend conjunction of two anesthesia techniques in patients undergoing short duration laparoscopic surgeries.
