Effection of canal block combined with general anesthesia in abdominal surgery of low birth weight neonates
Objective To observe the effect of caudal block combined with general anesthesia in abdominal surgery of low birth weight neonates.Methods A total of 100 low birth weight neonates who underwent elective abdominal surgery were divided into two groups by random number table method:caudal block combined with general anesthesia group(group CG,n=50)and general anesthesia group(group G,n=50).Neonates in both groups were induced by sevoflurane inhalation anesthesia.After tracheal intubation,1％～2％ sevoflurane was inhaled to maintain anesthesia.The neonates in group G were continuously pumped with remifentanil 0.5 μg/(kg·min)during surgery,while the neo-nates in group CG underwent ultrasound-guided caudal block in the left lateral position,and 0.2％ ropivacaine 1 mL/kg was injected.The operation time,tracheal tube extraction time(time from the end of surgery to extubation)and the post-anesthesia care unit stay time of the two groups were recorded.Heart rate and mean arterial pressure of the two groups of neonates before anesthesia induction(T0),immediately after tracheal intubation(T1),incision(T2),ab-dominal exploration(T3),closing the abdominal cavity(T4),immediately after extubation(T5)and out of the operat-ing room(T6)were recorded.The occurrence of adverse events such as respiratory depression during the wake-up peri-od and during the post-anesthesia care unit stay in the two groups were recorded.The first defecation time and hospital stay of the two groups of neonates after operation were recorded.And the incidence of complications of caudal block in group CG were recorded.Results The tracheal tube extraction time and the post-anesthesia care unit stay time of group CG were significantly shorter than those in group G(P＜0.05).The heart rate of neonates in group CG was signif-icantly lower than that in group G at T2～6,and the mean arterial pressure of neonates in group CG was significantly higher than that in group G at T2～6(P＜0.05).The adverse events in group CG were significantly lower than those in group G during the wake-up period and during the post-anesthesia care unit stay(P＜0.05).The time of first defecation in group CG was significantly shorter than that in group G,and the difference was statistically significant(P＜0.05).The incidence of sacral canal-related complications in group CG was 0.Conclusion Caudal block combined with general anesthesia is used for abdominal surgery of low birth weight neonates to provide more complete intraoperative analgesia,intraoperative hemodynamic stability,low incidence of adverse reactions,and early recovery.
