Regional Nerve Blocks Improve Pain and Functional Outcomes in Hip Fracture: A Randomized Controlled Trial

Area of Science:

• Anesthesiology
• Orthopedic Surgery
• Pain Management

Background:

• Hip fractures are a common cause of morbidity and mortality in the elderly.
• Effective pain management is crucial for optimal recovery and functional outcomes after hip fracture surgery.
• Conventional analgesics may be associated with significant side effects, limiting their efficacy and patient tolerance.

Purpose of the Study:

• To compare the effectiveness of regional nerve blocks with standard analgesics for pain management and functional outcomes in patients with hip fractures.
• To evaluate the incidence of opioid-related side effects in both treatment groups.

Main Methods:

• A multisite randomized controlled trial involving 161 patients with hip fractures was conducted across three New York hospitals.
• Participants were randomized to receive either an ultrasound-guided femoral nerve block followed by a continuous fascia iliaca block or conventional analgesics.
• Pain scores, walking distance, functional mobility, and opioid side effects were assessed at various time points.

Main Results:

• The regional nerve block group demonstrated significantly lower pain scores at 2 hours post-emergency department presentation and on postoperative day 3.
• Patients receiving nerve blocks walked further on postoperative day 3 and reported improved walking and stair climbing ability at 6 weeks post-discharge.
• Opioid side effects were significantly less frequent in the nerve block group (3% vs 12.4%), with a 33%-40% reduction in opioid requirements.

Conclusions:

• Ultrasound-guided femoral nerve blocks followed by continuous fascia iliaca blocks are a feasible and superior method for managing pain in hip fracture patients.
• This regional anesthesia approach leads to improved pain control, enhanced functional recovery, and reduced opioid-related adverse events.
