Pericapsular Nerve Block in Proximal Femoral Fractures

Effect of Systemic Analgesia and Systemic Analgesia Associated With Pericapsular Nerve Block in Proximal Femoral Fractures

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.

Inclusion Criteria:

• patients with unilateral proximal femoral fractures admitted to the emergency room of the Hospital Sírio-Libanes,
• aged 18-105 years
• with the American Society of Anesthesiology (ASA) physical status I, II, or III.

Exclusion Criteria:

• allergy to metamizole and/or ropivacaine
• history of mental disorders
• presence of chronic pain as assessed using the Douleur Neuropathique 4 (DN4) questionnaire
