PurposeThe study aimed at investigating the effect of local infiltration analgesia (LIA) with ropivacaine on postoperative analgesia for patients undergoing ankle fracture surgery.MethodsConsecutive patients were retrospectively included and analysed according to their medical records from July 2014 to August 2018 in a tertiary hospital. Inclusion criteria were patients undergoing open reduction and internal fixation (ORIF) for ankle fractures under general anaesthesia. Moreover, patients should have received intravenous patient-controlled analgesia (iPCA) or LIA + iPCA for postoperative pain relief. The primary outcome indicator was visual analogue scale (VAS) from 8 hours to 48 hours after surgery. Secondary outcomes included postoperative opioid requirement, need for rescue medication, opioid-related adverse effects, and wound complications.ResultsIn total, 89 consecutive patients were included in the study. There were 48 males and 41 females. The average age was 44.6 ± 7.0 years, and VAS scores were significantly lower in the LIA + iPCA group at 8 hours after surgery (1.51 ± 0.58 cm vs 4.77 ± 1.83 cm, p < 0.001). The time to first tramadol consumption was longer (580 ± 60.9 minutes vs 281 ± 86.4 minutes, p < 0.001). The time to first tramadol consumption was longer (580 ± 60.9 minutes vs 281 ± 86.4 minutes, p < 0.001). The time to first tramadol consumption was longer (580 ± 60.9 minutes vs 281 ± 86.4 minutes, p < 0.001). The time to first tramadol consumption was longer (580 ± 60.9 minutes vs 281 ± 86.4 minutes, p < 0.001). The time to first tramadol consumption was longer (580 ± 60.9 minutes vs 281 ± 86.4 minutes.ConclusionsThe retrospective cohort study indicates that LIA with ropivacaine can provide better early postoperative pain management with a reduction of VAS scores for ankle fracture surgery. Patients receiving wound infiltration also experience decreased opioid consumption, a lower rate of analgesia-related side effects, and comparable wound complication rate.Copyright © 2020 Bao-Liang Li et al.
