To investigate the efficacy and safety of ultrasound-guided transversal abdominal block combined with ketamine anesthesia and ketamine anesthesia alone in children with inguinal hernia surgery.

From September 2018 to March 2020, 80 children with inguinal hernia who were admitted to the Affiliated Hospital of North Sichuan Medical College were selected as the research subjects, and the patients were divided into observation group and experimental group according to different anesthesia plans, with 40 children in each group. example. The anesthesia plan of the observation group was intravenous ketamine anesthesia alone; the anesthesia plan of the experimental group was ultrasound-guided lower abdominal transverse plane block combined with ketamine anesthesia. The vital signs, anesthesia quality and entry into anesthesia were compared between the two groups at different time points [before skin incision (T0), 10 minutes after skin incision (T1), 15 minutes after skin incision (T2), and exploration of hernia sac (T3)]. Pain and sedation at different time points after the recovery room [immediately after entering (T4), 20 minutes after entering (T5), and 40 minutes after entering (T6)], as well as adverse reactions in the two groups.

The heart rate and mean arterial pressure at T1, T2, and T3 in the experimental group were significantly lower than those in the observation group (P<0.05); there was no significant difference in anesthesia induction time between the two groups (P>0.05). The recovery time of the experimental group was significantly lower than that of the observation group (P<0.05); the Eastern Ontario Children's Hospital pain scale score and Watcha sedation score at T4, T5 and T6 of the experimental group were significantly lower than those of the observation group (P<0.05). The incidence of adverse reactions in the experimental group was significantly lower than that in the observation group (P<0.05).

Ultrasound-guided transverse abdominal plane block combined with ketamine anesthesia has a significant anesthesia effect on children with inguinal hernia surgery. The anesthesia scheme can not only obtain more stable fluid dynamic characteristics, shorten the recovery time of children from anesthesia, but also improve children's surgery. Pain and sedation.
