Purpose:
The study aimed at investigating the effect of local infiltration analgesia (LIA) with ropivacaine on postoperative analgesia for patients undergoing ankle fracture surgery.
Methods:
Consecutive 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.
Results:
In 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.
Conclusions:
The 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.
