Local ketorolac infiltration for postoperative pain in open trigger finger surgery: a randomized controlled trial

Abstract

Abstract Background Multimodal analgesia is crucial for effective postoperative pain management in minor hand surgeries, enhancing patient satisfaction. The use of local wound infiltration with Ketorolac as an adjuvant pain management strategy is proposed for open trigger finger release surgery. This study aims to compare pain scores and functional outcomes between local wound infiltration with Ketorolac and oral non-steroidal anti-inflammatory drugs. Methods This study is a double-blind, parallel design, randomized controlled trials. Sixty-nine patients underwent trigger finger surgery between December 2021 and October 2022 were randomized into one of three groups: oral Ibuprofen alone group, local Ketorolac alone group and local Ketorolac with oral Ibuprofen group. The assessment included postoperative numeric rating scale (NRS) pain score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, grip strength, mobility of proximal interphalangeal (PIP) joint. and complications. Results NRS pain scores during movement of the operated fingers were significantly lower at 6 h in local Ketorolac alone group and local Ketorolac with oral Ibuprofen group compared to oral Ibuprofen alone group. However, there were no significant differences between the groups in postoperative DASH scores, grip strength, mobility of PIP joints, and complications. Conclusions Local infiltration of Ketorolac as an adjunct in postoperative pain management has been shown to provide superior analgesia during finger movement within the initial 6 h following trigger finger surgery, in comparison to oral NSAIDs.
