小儿先天性心脏病术后心律失常的临床特点与影响因素

Clinical Characteristics and Influencing Factors of Postoperative Arrhythmia in Children With Congenital Heart Disease

目的分析小儿先天性心脏病术后心律失常的临床特点及其影响因素。方法对268例行先天性心脏病直视手术的患儿进行分析,了解术后心律失常的发生情况,并对相关影响因素进行探究。结果本组68例患儿术后发生心律失常,占25.4%,心律失常类型以室上性心动过速为主;影响心律失常发生的因素为年龄、心功能、体外循环时间、阻断主动脉时间、术后低血钾、术后低心排出量(P<0.05)。结论心律失常是危害先天性心脏病患儿术后生存质量的严重并发症,其发生与围手术期相关因素有着密切联系,应采取有效措施进行预防。

Objective To analyze the clinical characteristics and infuencing factors of postoperative arrhythmia in children with congenital heart disease. Methods 268 cases of congenital heart disease were analyzed, and the incidence of postoperative arrhythmia was observed, and the related factors were explored. Results The occurrence of arrhythmia, 68 cases of postoperative accounted for 25.4%, the type of arrhythmia supraventricular tachycardia; influencing factors of arrhythmia with age, heart function, cardiopulmonary bypass time, aortic clamping time, postoperative hypokalemia, postoperative low cardiac output （P 〈 0.05）. Conclusion Arrhythmia is a serious complication of postoperative quality of life in children with congenital heart disease, and its occurrence is closely related to perioperative factors, and effective measures should be taken to prevent it.
