Efficacy of Continuous Peripheral Nerve Block in Patients with Proximal Femur Fracture

Abstract

Objective: To evaluate the efficacy of continuous peripheral nerve block in reducing pain, decreasing opioid consumption, and improving functional outcomes in patients with proximal femur fractures.

Methodology: This prospective study was conducted on 100 patients presenting with proximal femur fractures. Patients received continuous peripheral nerve block using a catheter-based technique. Pain was assessed using the Visual Analog Scale (VAS) at baseline and at 6, 12, 24, and 48 hours post-intervention. Secondary outcomes included opioid consumption, early mobilization, patient satisfaction, and procedure-related complications. Data were analyzed using appropriate statistical methods.

Results: The mean VAS score significantly decreased from 8.5 ± 1.2 pre-block to 2.3 ± 0.7 at 48 hours post-block (p < 0.001). A majority of patients (65%) did not require additional opioid analgesia, while those who required opioids had reduced mean consumption (12.5 ± 4.3 mg morphine equivalents). Early mobilization within 48 hours was achieved in 70% of patients. Patient satisfaction was high, with 75% reporting satisfactory pain control. Complications were minimal, with the majority of patients (82%) experiencing no adverse effects.

Conclusion: Continuous peripheral nerve block is an effective and safe modality for pain management in patients with proximal femur fractures. It significantly reduces pain scores, minimizes opioid requirements, and facilitates early mobilization, thereby improving overall patient outcomes.
