| 目的 探讨应用超声心动图肺部超声评分定量评价先天性心脏病儿童手术前后肺水含量的可行性。
方法 应用超声心动图观察88例不同先天性心脏病患儿手术前肺部声像图改变并评分；比较手术前后肺超声评分的差异，以及肺评分与Qp/Qs （肺循环血流量与体循环血流量比值）的关系。
结果（1）房间隔缺损（ASD)、室间隔缺损（VSD）及完全型肺静脉异位引流（TAPVD）术后的肺评分总分显著均低于术前（P<0.01）; 法洛四联症(TOF)术后与术前肺评分无明显差异（P﹥0.05）。（2）VSD与TAPVD的术前肺评分总分与Qp/Qs呈正相关（P<0.01）。
结论 超声心动图肺超声评分变化能够反映肺含水量的变化，有助于评估先心病围手术期的心肺功能，筛选危重患儿，指导临床早期干预。 |

| Abstract: |
| Objective: To explore the application of lung ultrasound score by echocardiography in evaluating extravascular lung water before and after operation in children with congenital heart disease.
Method: 88 cases of children with congenital heart disease were analyzed before and post operative with echocardiography. Lung water were observed through different windows. Lung ultrasound scores derived from chidren before surgery was compared with those from postoperative, and the relationship between lung ultrasound scores and Qp /Qs was analyzed.
Results Lung ultrasound scores of the children with ventricular septal defect (VSD), atrial septal defect (ASD) and total anomalous pulmonary venous drainage (TAPVD) were higher before surgery than postoperative (P <0.01), but there was no significant difference (P﹥0.05) between them in Tetralogy of Fallot (TOF) group. Lung ultrasound scores of children with VSD and TAPVD before surgery positively correlated with Qp/Qs (P<0.01).
Conclusion: Lung ultrasound scores derived from echocardiography can reflect the changes of extravascular lung water of children with congenital heart disease during perioperative, and be used to assess the heart and lung function of the patients, screen critically ill children, guidline clinical early intervention. |
