Objectives: To determine whether the use of peripheral nerve blocks (PNBs) as part of an analgesic protocol for operative repair of tibia and ankle fractures can improve the quality of postoperative pain management and the quality of recovery (QOR).
Study design: Prospective cohort study.
Setting: Orthopedic trauma service in an academic tertiary care center.
Patients: Ninety-three consecutive patients undergoing operative repair of fractures of the ankle and tibia.
Intervention: Administration of popliteal and saphenous nerve blocks, as part of postoperative analgesia regimen in some patients. Patients were labeled as the regional group or the no-regional group based on whether they received PNBs.
Outcomes: Patient satisfaction and the quality of pain management were measured 24 hours after surgery using the Revised American Pain Society Patient Outcome Questionnaire. The QOR was measured at 24 and 48 hours after surgery using the short version of the Quality of Recovery Questionnaire (QOR-9).
Results: Satisfaction with pain management was significantly higher (P = 0.005) in the regional group when compared with the no-regional group. Average pain scores over 24 hours was similar between the 2 groups (P = 0.07). The regional group reported less time spent in severe pain over 24-hour period (40 vs. 50%, P = 0.04) and higher overall perception of pain relief (80 vs. 65%, P = 0.003). Patients receiving regional anesthesia also demonstrated better QOR measured by the QOR-9 at 24 hours (P = 0.04) but not at 48 hours (p = 0.11).
Conclusions: Patient satisfaction and the quality of postoperative pain management for the first 24 hours were better in patients who received PNBs as part of their postoperative analgesic regimen when compared with patients who received only systemic analgesia.
