左向右分流型先天性心脏病由于肺循环血量增加,易并发呼吸道感染。由于分流,体循环血量减少,活动后易气促,严重者常发生心功能不全。我们在左向右分流型先心病并发肺炎或心力衰竭的病儿身上常观察到病儿的酸中毒常较一般无先心病的肺炎病儿重。为了了解无并发症时的左向右分流型先心病病儿的血气情况,我们对行右心导管检查及部分心外科行根治术的22例左向右分流型先心病病儿术前进行了动脉血气测定,
Left to right shunt congenital heart disease due to increased blood volume of the pulmonary circulation, complicated by respiratory tract infections. Due to shunt, reduce systemic blood volume, easy to promote gas after the event, severe heart failure often occur. We often observed in children with left-handed and right-handed shunt congenital heart disease complicated with pneumonia or heart failure, their acidosis was more common in children with pneumonia than in those with no congenital heart disease. In order to understand the blood gas situation of children with left-right shunt congenital heart disease without complications, we performed preoperatively on 22 cases of left-right shunt congenital heart disease undergoing right-sided catheterization and partial cardiac surgery Arterial blood gas determination,
