In the past, inguinal hernia surgery often required lumbar or general anesthesia, but for elderly patients with many underlying diseases, the use of lumbar or general anesthesia may place a greater burden on cardiopulmonary function and may not be able to tolerate anesthesia. In this regard, we are the first in the region to carry out hernia repair under local anesthesia, which is local nerve block anesthesia, injecting highly concentrated anesthetic drugs for local nerves, with good anesthesia effect and less anesthesia, and less postoperative pain, so that patients can eat and drink normally before surgery and do not need to put down the urinary catheter, and can move around after surgery. This technique is especially suitable for elderly and frail patients suffering from various chronic diseases, which broadens the indications for surgery. Since this technique was developed, many elderly patients in their eighties and nineties have been able to undergo surgery successfully, often combined with severe hypertension, cardiovascular and cerebrovascular diseases, old chronic diseases and other underlying diseases, and we have even successfully performed hernia surgery on centenarians. In addition, hernia surgery under local anesthesia has led to a significant reduction in hospitalization costs (saving about 1/3 of the hospitalization costs compared to traditional anesthesia), and patients can walk on the floor after the surgery, and some patients can even complete the surgery during the day without hospitalization.
