What this trial studies

This study aims to compare the effectiveness of two ultrasound-guided nerve blocks, the Supra-inguinal Fascia Iliaca Block (S-FICB) and the Pericapsular Nerve Group Block (PENG), in providing pain relief for patients undergoing surgery for femur fractures. Patients will be randomly assigned to one of the two groups, and their pain levels will be assessed before and after the procedure using a numeric pain rating scale. The study will utilize a double-blind design to ensure unbiased results, with both the observer and patients unaware of the group assignments. The goal is to determine which nerve block technique offers superior analgesic efficacy during and after surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 20 to 70 years with a radiologically confirmed femur fracture and classified as ASA Class I, II, or III.

Not a fit: Patients who may not benefit include those with contraindications to spinal anesthesia or peripheral nerve blocks, significant cognitive impairment, or those who do not experience pain while sitting.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing femur fracture surgery.

How similar studies have performed: While both nerve blocks have been studied individually, this is one of the few studies comparing their efficacy under ultrasound guidance, making it a novel approach.
