Transcatheter Aortic Valve Implantation: Comparison of the Effects of Ultrasound-Guided Pericapsular Nerve Group Block and Fascia Iliaca Block on Postoperative Analgesia Management

Summary

Aortic Stenosis (AS) is the most common valvular pathology, particularly prevalent in advanced age, and Transcatheter Aortic Valve Implantation (TAVI) has become a crucial treatment option for high-risk patients who are not suitable for surgery. This minimally invasive approach has demonstrated successful clinical outcomes in patients deemed ineligible for surgical procedures. Patient selection criteria and advancements in operative techniques are critical for achieving successful TAVI outcomes. While the transfemoral approach is the most commonly used method, alternative techniques such as transapical, transaxillary, transcarotid, and transaortic approaches are also available. The Pericapsular Nerve Group Block (PENG) targets the femoral and accessory obturator nerves, providing analgesia to the anterior hip without causing motor block. The Fascia Iliaca Block (FIB), on the other hand, provides broader analgesic coverage by affecting the lateral femoral cutaneous, obturator, and femoral nerves. This study aims to compare PENG block, FIB, and local infiltration anesthesia in TAVI patients regarding sedation requirements during the procedure and postoperative analgesia management. Additionally, pain scores, motor block presence, opioid consumption, and side effects will be assessed. The study seeks to identify optimal strategies to enhance patient comfort and safety during TAVI procedures.
