Proximal femoral fractures commonly occur above 50 years and regional anesthesia could be a complement in the perioperative treatment of the patients. The use of pericapsular nerve group block (PENG Block) has been proposed to reduce pain. However, no studies have explored the efficient of the systemic analgesia associated with PENG Block in functional limitation in the preoperative period. In this sense, the main goal of this study is to evaluate the effectiveness of systemic analgesia associated with PENG Block in patients with proximal femoral fractures in the period preceding the surgical procedure.
Focus on functional capacity will be measured by the Activity Measure for Post-Acute Care (AM-PAC) short version of the "6 Clicks", pain intensity will be assessed using the numerical rating scale, and opioid consumption. This study will include 21 patients admitted to the Emergency Room with proximal femoral fractures.

| PENG Block | Procedure | Patient will be placed in the supine position and the ultrasound probe will be placed in the transverse plane over the anterior inferior iliac spine (AIIS) and aligned with the pubic ramus by rotating the probe counterclockwise by approximately 45 degrees. A 22-gauge, 100 mm needle will be inserted using the plane approach from lateral to medial, between the psoas tendon anteriorly and the pubic ramus posteriorly. Following a negative aspiration, 20 mL of 0.375% ropivacaine will be injected. The needle position will be confirmed by visualizing the separation of layers with the dispersion of the injected volume. |
