摘要
目的 分析3岁以内患儿室间隔缺损心内直视手术后早期心律失常及其危险因素,以期降低术后心律失常的发生率。方法 对1993年1月～2001年12月间389例患儿术后心律失常发生类型及发生因素进行分析。结果 年龄≤1岁、心胸比值(C/T)≥0.5、室间隔缺损直径≥1 cm、合并肺动脉高压、补片修复缺损、主动脉阻断时间≥30min及术后低钾血症与术后心律失常有密切关系。结论 心律失常是室间隔缺损术后早期严重并发症;早期手术、缩短主动脉时间、维持术后24h内循环稳定、防止电解质紊乱和缺氧、酸中毒的发生,是降低3岁以内室间隔缺损手术后心律失常发生率的有效措施。
Objective To identify the risk factors resulting in arrhythmias after correction of ventricular septal defect in children under 3 years old so as to decrease the incidence of arrhythmias after the operation. Methods The types and risk factors of arrhythmias were analysed in 389 cases who underwent correction of ventricular septal defect from Jan. 1993 to Dec. 2001. Results Age≤1 year, C/T≥0.5, the diameter of ventricular septal defect≥1cm、pulmonary hypertension、patch repair, aortic-cross clamping time≥30min and postoperative hypokalemia were independent predictors of postoperative arrhythmias. Conclusion Arrhythmias remains the severe early complications after surgical treatment for ventricular septal defect in children under 3 years old. Early operation, shortening of aortic-cross clamping time, maintaining of normal circulation and electrolytes and prevent anoxia/acidosis, may be the most effective preventive measures to prevent arrhythmias after correction of ventricular septal defect in children under 3 years old.
