Intraarticular fentanyl compared with morphine for pain relief following arthroscopic surgery of knee
Journal Title: Medpulse International Journal of Anesthesiology - Year 2017, Vol 2, Issue 1
Abstract
Background and Aims: We sought to compare the analgesic effect of intra-articular administration of morphine, fentanyl and placebo following arthroscopic surgery of knee. Methods: A prospective, randomised, placebo controlled, double blind comparative study conducted in 60 patients of either sex, who underwent arthroscopic surgery of knee, between the age group of 18 and 65 years and of ASA class II physical status and I were included in the study. Patients were randomly assigned equally to one of the 3 groups of 20 each by a sealed envelope method. The groups were Group A- Patients receiving IA Fentanyl 50mcg in 20 ml normal saline. Group B - Patients receiving IA Morphine 3mg in 20 ml normal saline. Group C-Patients receiving IA 20 ml normal saline as placebo. Parameters monitored were degree of analgesia along with hemodynamic parameters and side effects. Data were analysed using student’s t-test for continous variables and Chi-Square test was used to find out the association between categorical variables. Results: Pain scores at one, two, four and eight hours were greater at all times in placebo group. Pain scores for fentanyl and morphine were similar at one hour, but thereafter less (p < 0.001) for IA-Fentanyl group. Conclusion: Intra-articular 50-mcg fentanyl provided better post-operative analgesia than 3mg morphine.
