In recent years, tension-free inguinal hernia repair has become very mature. In our hospital, the technique of preperitoneal repair was performed 8 years ago and is now proficient. This technique can solve many difficult hernias, while experiencing the preperitoneal placement of the patch, which can reduce the discomfort of the patient in the surgical area, and so far no case of hernia recurrence has been seen, relatively speaking, anesthesia complications are increasingly prominent. Inguinal hernia repair in adults is usually performed under lumbar or epidural anesthesia, and postoperative urinary retention and pain at the lumbar injection site affect the patient’s recovery. In order to improve the surgical requirements, local anesthesia was gradually introduced in our hospital three years ago. In the early stage of development, we selected patients who had contraindications to intralesional anesthesia, such as long-term oral aspirin affecting coagulation function, and needed general anesthesia for surgery, then we operated under local anesthesia first, and were ready to change to general anesthesia in time during surgery. With the increase in surgical experience, we appreciate the advantages of local anesthesia are as follows: 1, light postoperative pain. Anesthesia drug selection is a very important link, we experienced in the exchange with foreign experts in surgery, after adding long-acting ropivacaine, intraoperative anesthesia effect significantly improved, postoperative pain reduction. 2. Reduction of urinary retention and lumbar injection site pain, which are common complications in the spinal canal. Although we promptly gave feedback on the complications to the anesthesiologists and they made corresponding improvements in the dose, the incidence of these complications was still high relative to local anesthesia surgery. 3. Fast postoperative recovery. Most patients consider local anesthesia surgery as “minor surgery”, so the preoperative psychological pressure is light, coupled with the reduction of complications during surgery, patients can eat and get out of bed normally on the same day, which forms a virtuous circle and reduces postoperative systemic complications, such as venous thrombosis of the lower limbs and pulmonary infection. 4. The impact on the original disease is avoided, and the population adapted to the surgery is expanded. It makes the surgery possible for patients with combined systemic multiple diseases, especially when the patient has an ingrown hernia, the surgery is first performed by local anesthesia, and the contents of the hernia are observed after opening the hernia sac. Clinically, most patients have not necrosis of the contents, and the contents are retracted and then repaired, so the surgery becomes quite safe.
