Comparison of analgesic effects of pure bupivacaine and morphine added as bupivacaine adjuvant in USG guided adductor canal block following total knee arthroplasty
Objectives: Total knee arthroplasty (TKA) is an operation that causes severe postoperative pain. Adductor canal block (ACB) is separated from the other peripheral blocks as a method that can provide analgesia by sensory blockade only. The aim of this study was to compare the analgesic effect of morphine-bupivacaine with pure bupivacaine in USGguided ACB after TKA. Methods: Sixty patients aged between 40-80 years with ASA I-III physical status who were scheduled for TKA surgery in our hospital were included in this prospective randomized study. Patients were randomly divided into two groups as Group BM (bupivacaine+morphine) and Group B (bupivacaine) by closed envelope method, and then the groups were compared with each other. Results: In Group BM, compared to Group B, there was a significant decrease in visual analogue scale (VAS) values during rest and movement at 8th hour, 12-24 hours time zone analgesic consumption and additional analgesia usage. Conclusion: We conclude that the morphine added to bupivacaine in the adductor canal block reduces the VAS value at 8th hour and analgesic consumption.
