摘　　要：目的探讨小儿先天性心脏病(CHD)合并肺部感染时超声心动图表现。方法选取2011年7月至2014年6月济南军区总医院收治的CHD合并肺部感染患儿,观察感染控制前后患儿超声心动图表现。结果 CHD患儿肺部感染控制后,三尖瓣反流程度较控制前有显著好转(P<0.05);患儿肺部感染控制前肺动脉/主动脉收缩压比值为(0.89±0.21),显著高于感染控制后的比值(0.53±0.19),差异有统计学意义(P<0.05)。控制肺部感染前,室间隔缺损患儿心脏血流由左向右分流10例,由右向左分流8例;动脉导管未闭患儿心脏血流双向分流8例,由右向左分流4例;房间隔缺损患儿心脏血流由右向左分流8例。控制肺部感染后,室间隔及动脉导管未闭患儿心脏血流均为由左向右分流,房间隔缺损患儿心脏血流亦均为由左向右分流。结论 CHD患儿合并肺部感染时,室间隔缺损、动脉导管未闭患儿心脏血流并非全部表现为左向右分流,故超声心动图检查时应仔细分析。Objective Discussion of echocardiographic findings in children with congenital heart disease with pulmonary infection. Methods A total of 38 children admitted from July 2011 to June 2014 in our hospital with congenital heart disease and pulmonary infection were enrolled. Echocardiography exams were done before and after the infection being under control. Results The degree of tricuspid regurgitation was better after the infection control（ P〈0. 05）. Pulmonary artery / aortic systolic pressure ratio for children with pulmonary infection before the infection was controlled was higher than that after disease controlled（ 0. 89 ± 0. 21 vs. 0. 53 ± 0. 19,P〈0. 05）. 10 cases of ventricular septal defect（ VSD） showed left to right shunt and 8 VSD cases with right to left shunt before infection control. 8 cases of patent ductusarteriosus（ PDA） manifested bidirectional shunt and 4 PDA cases showed right to left shun. 8 patients with atrial septal defect（ ASD） showed right to left shunt. After the control of infection,left to right shunt was found in all VSD,PDA and ASD case 8. Conclusions In children with congenital heart disease and pulmonary infection,the blood flow through Ventricular septal defect and patent ductus arteriosus are not always from left to right shunting. Echocardiography exam should be carried out with caution.
