To explore the application of local nerve block anesthesia in tension-free repair of adult inguinal hernia.

336 patients with inguinal hernia admitted to Meishan People's Hospital from January 2021 to April 2023 were selected as the study subjects. The patients were randomly divided into 2 groups by random number table method, with 168 patients in each group. All patients underwent tension free hernia repair. The experimental group received local nerve block anesthesia. The control group received epidural anesthesia combined with lumbar anesthesia. The anesthesia and surgical time, postoperative water intake time, postoperative out of bed time, analgesia satisfaction rate, degree of pain, and the incidence of postoperative complications were compared between the two groups.

The anesthesia and surgical time, visual analogue scale score at 6 hours after surgery, postoperative water intake time, and postoperative out of bed time were better in the experimental than those in the control group, and the differences were statistically significant (P<0.05). The satisfaction rate of patients in the experimental group with analgesic effects 24 hours after surgery was higher than that in the control group, and the difference was statistically significant (P<0.05). No patients experienced local anesthetic poisoning or cardiovascular accidents after surgery in two groups. There was no statistically significant difference in the incidence of postoperative complications between the two groups (P>0.05).

Local nerve block anesthesia can not only reduce the time for surgery, anesthesia, postoperative water intake time, and postoperative out of bed time, but also improve comfort and satisfaction of patients.
