To explore the effect of general anesthesia combined with ultrasound guided ilioinguinal nerve block and rectus abdominis sheath block on anesthesia and analgesia in patients undergoing inguinal hernia repair.

60 patients who underwent inguinal hernia surgery in Ma'anshan People's Hospital from August 2019 to June 2022 were selected as the study subjects. All patients were divided into the control group and the observation group according to the random number table method, with 30 patients in each group. Laparoscopic total extraperitoneal hernia repair (TEP) was performed in both groups. The patients in the control group were given general anesthesia. Patients in the observation group were treated with general anesthesia combined with ultrasound guided ilioinguinal nerve block and rectus abdominis sheath block. The dosage of anesthetic drugs (propofol and remifentanil) was compared between the two groups. The changes of vital signs (mean arterial pressure, heart rate, blood oxygen saturation before operation, at the time of skin incision and at the time of awakening) and the pain in resting state and cough state (pain degree 2 h, 4 h, 8 h, 12 h, 24 h and 48 h after operation) [Visual analog scale (VAS)] were compared between the two groups.

The dosage of propofol and remifentanil in the observation group was lower than that in the control group (P<0.05). There was no significant difference in mean arterial pressure and heart rate between the two groups before surgery and at the time of awakening (P>0.05), and there was no significant difference in blood oxygen saturation between the two groups before operation, at the time of skin incision and at the time of awakening (P>0.05). The mean arterial pressure and heart rate in the control group were higher than those in the observation group at the time of skin incision (P<0.05). The VAS scores in the observation group at rest and cough at 2 h, 4 h, 8 h after operation were lower than those in the control group (P<0.05). There was no significant difference between the two groups in VAS scores at 12 hours, 24 hours, 48 hours after surgery (P>0.05).

For patients with inguinal hernia undergoing TEP repair, the method of general anesthesia combined with ultrasound guided ilioinguinal nerve block and rectus abdominis sheath block had a better anesthetic effect than general anesthesia, which can reduce the use of anesthetic drugs and postoperative short-term pain.
