喉罩在小儿先天性心脏病介入治疗麻醉中的应用

目的探讨喉罩在小儿先天性心脏病介入治疗麻醉中的优越性。方法选择先天性心脏病介入治疗患儿60例,随机分为喉罩组（L组）和气管插管组（T组）,氯胺酮组（K组）,每组20例。分别观察各组在麻醉诱导前、麻醉诱导后及喉罩或导管置入前、置入后、拔除前、拔除后的血氧饱和度（SpO2）、心率（HR）、平均动脉压（MAP）和术后恢复情况。结果 L组置入喉罩后和拔除喉罩后的MAP、HR低于T组（P〈0.05）,术后呼吸系统并发症L组低于T组（P〈0.05）,术中肢动人数K组高于L组及T组。结论喉罩在小儿先天性心脏病介入治疗的麻醉中安全,可行。

The application of laryngeal mask airway for general anesthesia in the interventional therapy of children with congenital heart disease

Objective To explore the feasibility and safety of laryngeal mask airway for general anesthesia in the interventional therapy of children with congenital heart disease. Methods Sixty children with congenital heart disease were randomly divided into three groups：laryngeal mask airway group（L group）,endotracheal intubation group（T group）and ketamine groups.SpO2,HR and MAP were recorded at different terms in L and T group.The conditions of recovery after anesthesia in three groups were observed.Results The values of HR and MAP were significantly higher in T group than that in L group at application of endotracheal tube and extubation points（P0.05）.Postoperative respiratory complications in L were significantly lower than that in T group.Conclusion The application of laryngeal mask airway for general anesthesia in the interventional therapy of children with congenital heart disease is safty and feasible.
