Abstract: Objective To investigate the effect of general anesthesia combined with transversus abdominis plane block (TAP) and Inferior iliac and inguinal nerve block (INB) on patients undergoing laparoscopic hernia repair. Methods From June 2021 to May 2022, 80 patients with laparoscopic hernia repair who were treated in Jingjiang Hospital of Traditional Chinese Medicine were prospectively selected as the research objects, and they were divided into the study group (n=40) and the control group by random number table method (n=40). The control group was given TAP, and the study group was given INB anesthesia. To compare the efficacy of the two groups, the physical signs [blood pressure (MAP), heart rate (HR), blood oxygen saturation (SpO₂)], adverse reactions and anesthesia indicators (wake time, pain score after anesthesia, amount of fentanyl, time of directional force recovery). Results The anesthesia rate of anesthesia in the study group was higher than that in the control group (P<0.05). There was no difference in MAP, HR, and SpO₂ sign indicators between the two groups (P>0.05), MAP and HR decreased 2 min after nerve block in the two groups, and the study group were lower than the control group (P<0.05), and no significant difference between SpO₂ indicators (P>0.05). After comparison, the incidence of adverse reactions in the study group was significantly lower than that in the control group group (P<0.05). The recovery time, post-anesthesia analgesia score, fentanyl dosage, and directional force recovery time were all shorter or less than that of the control group (P<0.05). Conclusion Ilioinguinal nerve block can be used in laparoscopic hernia repair. The anesthesia effect is stable, the patient's physique index is stable, and the incidence of side effects is small, which is worthy of application.
