Comparative evaluation of efficacy of intravenous paracetamol and intravenous diclofenac as post-operative analgesia in laparoscopic cholecystectomy
Background: Though laparoscopic cholecystectomy is a minimal invasive surgery but inadequate pain management interferes with early discharge of patient. Administration of opioid for pain relief is a concern because of its side effects. To avoid this problem, we planned our study to find out the best alternative of opioid in patients undergoing laparoscopic cholecystectomy.
Methods: 68 patients were enrolled for this study in a stipulated time of 1 year in a tertiary level hospital. A questionnaire was responded by patients and a chart was maintained for pain score in visual analogue scale (VAS) and for side effects. We used paracetamol and diclofenac as post operative analgesic in two different groups and data was recorded in Excel panel and was analyzed by standard statistical test by software MINITAB 1513 with a significant p- value of <0.05.
Results: We have found the significant outcome (p-values are 0.0005 at 0 hrs, 0.003 at 2 hrs, 0.001 at 6 hrs, 0.0005 at 12 hrs) in VAS pain score in between the two groups at different intervals. Patients who were administered paracetamol had shown better outcome with less requirement of rescue analgesia and side effects.
Conclusion: Administration of intravenous paracetamol in the intra operative period 30 minutes prior to the completion of surgery followed by administration of 1g paracetamol every 8 hourly in the post-operative period gives better quality of analgesia.
