Abstract

Background- Intensity of pain in early post-operative period after laparoscopic cholecystectomy is signicant. There are several methods employed in the management of postoperative pain after laparoscopic cholecystectomy such as conventional systemic analgesics, including paracetamol, non-steroidal anti-inammatory drugs, systemic opioids, and thoracic epidural analgesia with all having its limitations and side effects. Objective- The present study aims to compare ultrasound-guided subcostal transversus abdominis (STA) block with intraperitoneal instillation of bupivacaine in reducing postoperative pain, total analgesic consumptions after elective laparoscopic cholecystectomy. Materials and methods: 60 adult patients were randomly divided into 2 groups of 30 in each. The selected patients were randomly divided into two groups Group 1, patients received USG guided tap block before surgery. Group 2 patients received 40 ml of 0.25 % bupivacaine after surgery, instillation done by surgeon intraperitoneally at gall blabber bed and under the domes of diaphragm. Statistical analysis: In all Quantitative data were expressed in mean and standard deviation. Qualitative data were expressed in proportion and percentages. To nd the signicant difference between the bivariate samples in independent groups the Unpaired sample t-test and the Mann-Whitney U test was used. Above statistical tools the probability value > .05 was considered as signicant level. Results: The mean Numerical Rating Scale scores were less in Group 1 than in Group 2 from 1 hours to 24 hours and it was statistically signicant. Demand of rescue analgesia was higher in group 2 when compared to group 1 and it was statistically signicant. Conclusion: TAP block is a better modality for analgesia compared to intraperitoneal instillation in patients undergoing elective laparoscopic cholecystectomy
