Objectives: To determine the efficacy of a preoperative fascia iliaca compartment block in decreasing postoperative pain and improving functional recovery after hip fracture surgery. Design: Randomized prospective Level 1 therapeutic. Setting: Academic Level 1 trauma center. Patients: Geriatric patients with fractures of the proximal femur (neck, intertrochanteric, or subtrochanteric regions) were prospectively randomized into an experimental (A) or control (B) groups. Forty-seven patients met inclusion criteria, 23 randomized to the experimental group and 24 to the control group. Intervention: Patients randomized to the experimental group received an ultrasound-guided fascia iliaca compartment block administered by a board-certified anesthesiologist immediately before the initiation of anesthesia. Main Outcome Measurements: Primary outcome measure was postoperative pain medication consumption until postoperative day 3. Secondary outcomes included functional recovery and a study-specific patient-reported satisfaction survey assessed on postoperative day 3. Results: There was no significant difference in consumption of acetaminophen for mild pain, tramadol for moderate pain, or functional recovery between the 2 groups. There was a statistically significant decrease in morphine consumption (0.4 mg vs. 19.4 mg, P = 0.05) and increase in patient-reported satisfaction (31%, P = 0.01). Conclusions: Preoperative fascia iliaca compartment block significantly decreases postoperative opioid consumption while improving patient satisfaction. We recommend the integration of this safe and efficacious modality into institutional geriatric hip fracture protocols as an adjunctive pain control strategy.
