PENG Block forTranscatheter Aortic Valve Implantation

Summary

Pericapsular nerve group (PENG block) is a new fascial block defined by Arango et al. This block aims to block the femoral nerve and the accessory obturator nerve by injecting local anesthetic between the pubic ramus and psoas tendon. By blocking these nerves, anterior hip analgesia is created. It is a safe and effective method as it is applied superficially and under ultrasound guidance. In radiological and cadaver studies, it has been reported that when high volume is applied, total hip analgesia can be achieved by blocking the lateral femoral cutaneous, genitofemoral, obturator, and femoral nerves.
