Hernia is usually seen in older patients, and many elderly people are often combined with different degrees of diseases, such as poor cardiopulmonary function, liver and kidney insufficiency, poor coagulation and lumbar spine injuries, which prevent patients from performing general anesthesia and hemi-anesthesia (lumbar anesthesia) due to their own physical factors, resulting in untimely treatment of the disease, delaying the best time for treatment, and even delaying the development of serious hernia complications such as incarcerated hernia. For such patients, surgery under local anesthesia is a feasible option. Local anesthesia has little effect on the patient’s whole body, and has minimal impact on the patient’s heart, lungs, liver, kidneys and other organs, thus ensuring a smooth operation. Hernia repair under local anesthesia places higher demands on the surgeon. The surgeon must not only be extremely familiar with the anatomy of the local nerves, but also be able to provide precise anesthesia for the inferior iliac abdominal and iliac inguinal nerves under “precise guidance” and mixed with local infiltration anesthesia to ensure that the patient remains pain-free during the operation; moreover, the operation must be completed quickly under extremely skilled operation to further reduce the impact of surgical trauma on the patient.
