目的 :探讨先天性心脏病 (先心 )潜在青紫型并发肺炎的临床及血气特点。方法 :观察先心并发肺炎 65例与单纯性肺炎 5 8例的临床症状、并发症及血气分析特点 ,并将二者进行比较。结果 :先心肺炎组的临床症状及肺部体征较单纯性肺炎组重且持续时间长 ,血气分析显示前者动脉氧分压、动脉氧饱合度较后者下降程度重 ,高碳酸血症、代谢性酸中毒亦较后者发生率高 ,且两组血气分析改变均较临床症状出现早。结论 :先心肺炎组的临床症状较单纯性肺炎组严重 ,并发症发生率高且难以纠正。而低氧血症、高碳酸血症及代谢性酸中毒前者亦较后者改变显著。
Objective: To investigate the clinical and blood gas characteristics of potential cyanosis complicated pneumonia in congenital heart disease (congenital heart disease). Methods: Clinical symptoms, complications and blood gas analysis of 65 patients with congenital pneumonia and 58 patients with simple pneumonia were observed and compared. Results: The clinical symptoms and lung signs of CHD group were longer and longer than those of CHD group. Blood gas analysis showed that the former had lower partial pressure of oxygen and lower degree of arterial oxygen saturation than the latter, hypercapnia, Acidosis is also more frequent than the latter, and blood gas analysis changes in both groups appear earlier than clinical symptoms. Conclusions: The clinical symptoms of CHD group are more serious than those of simple pneumonia group. The incidence of complications is high and difficult to correct. The hypoxemia, hypercapnia and metabolic acidosis former than the latter also changed significantly.
