The Efficacy of Transdermal Diclofenac Patch for Postoperative Analgesia in Comparison with Intramuscular Diclofenac in Patients Undergoing Lower Abdominal and Perineal Surgeries Under Sub-Arachnoid Block A Randomised Comparative

Abstract

Background: Although, postoperative pain is a distinctive and most common form of pain, it remains poorly treated. Aim: To evaluate the efficacy of Transdermal diclofenac patch versus IM diclofen patients undergoing lower abdominal and perineal surgeries under Subarachnoid during postoperative period. Methodology: This randomised comparative study included 90 ASA I and II patien either sex aged 18 – 60 years. Patients were randomly divided by computer generated into two groups of 45 patients each. Group A was applied with a Transdermal Diclofenac (100mg) at the beginning of surgery after subarachnoid block. In groupB 75mg of Diclofenac sodium was given intramuscularly half an hour befo end of surgery. Data was analysed using Chi-square test and Mann Whitney U test Results: The mean difference in the time of administration of rescue analgesia in grou 8hr 37 mins ± 1 hr 4.2 mins and group B is 6hrs 19 mins ±58.6 mins ( P value is < 0.0001 ) effects in group A were very minimal. Conclusion: Thus transdermal diclofenac patch is effective, non- invasive and safer w treating postoperative pain. Keywords: Transdermal Diclofenac Patch, Im Diclofenac, Postoperative Analgesia.
