Application value of ultrasound-guided caudal anesthesia in infants for pediatric hernia surgery

Abstract

Objective To study on the application value of ultrasound-guided caudal anesthesia in infants for pediatric hernia surgery. Methods 100 children were treated with pediatric hernia surgery in Army Characteristic Medical Center from January 2016 to December 2016. They were considered as study objects and the clinical data were analyzed retrospectively. They were divided into observation group (n=52) and control group (n=48). The patients were treated with ultrasound-guided caudal anesthesia in the observation group, while the patients were treated with positioning of sacral puncture by resistance disappearance technique in the control group. The anesthetic effect was observed and compared. Results (1) Puncture time, number of puncture, dosage of ketamine, time to leave operating room after operation and postoperative recovery time in the observation group were significantly lower than the control group (P 0.05). After pneumoperitoneum, HR, MAP and PetCO2 levels in the observation group were significantly higher than those in the control group (P<0.05). However, there was no significant difference in BP, SpO2 and pH before and after treatment (P<0.05). (6) The incidence of adverse reactions in the observation group was significantly lower than the control group (P<0.05). Conclusion Ultrasound guided caudal anesthesia applied in pediatric hernia surgery has the advantages of accurate positioning, short recovery time, and better analgesic effect. Besides, it can reduce the restlessness in awakening period and improve the blood gas and circulation. This method is safe and effective, being worthy of further clinical promotion and application.
