Research progress on the application of regional block anesthesia in inguinal hernia surgery

Inguinal hernia is a common surgical disease, which is more and more common in the elderly and children. With the aging of the population and the opening of the second child, there are more and more patients with inguinal hernia surgery, and the difficulty and risk of anesthesia management are increasing. With the application of ultrasound visualization technology in anesthesia field, regional block anesthesia technology is guaranteed and developed. Regional block anesthesia is increasingly used in inguinal hernia surgery, especially in the elderly and children for anesthesia and analgesia. At present, regional anesthesia methods have emerged in endlessly. This article reviews the methods including paravertebral nerve block (PVNB), lumbar plexus nerve block (LPNB), quadratus lumborum block (QLB), ilioinguinal/iliohypogastric nerve block (IINB) and transversus abdominis plane block (TAPB) of regional block anesthesia for inguinal hernia surgery, and to explore the best.
