To explore the effect on physiological parameters of children with inguinal hernia surgery by using ultrasound-guided ilioinguinal-iliohypogastric nerve block (IINB) and general anesthesia.

From February 2017 to October 2018, 110 children undergoing open high ligation of hernial sac for inguinal hernia surgery in PLA Airborne Army Hospital were randomly divided into the control group and the observation group, with 55 cases in each group. The control group was treated with general anesthesia only, while the observation group was treated with INNB on the basis of the control group. The operation conditions, adverse reactions and physiological parameters, the level of immune stress were observed and compared between the two groups.

The incidence of adverse reactions was 10.91% (n=6) in the observation group and 7.72% (n=4) in the control group, and there was no significant difference between the two groups (P>0.05). There was no significant difference in retention time in postoperative anesthesia recovery room after operation, recovery time and operation time between the two groups (P>0.05). The levels of the heart rate and mean arterial pressure of the children in the observation group were lower than those in the control group at the time to wake up and 6 hours after operation (P<0.05). The levels of cortisol and interleukin-6 in the observation group were lower than those in the control group when waking up and 6 hours after operation (P<0.05).

On the basis of general anesthesia, combined with ultrasound-guided IINB will not increase the incidence of postoperative adverse reactions in children with inguinal hernia surgery, but its postoperative stress response has little influence and the vital signs of children are more stable.
