| 摘 要： | 小儿先天性心脏病通常可分为发绀型与非发绀型.由于不同程度的左向右或右向左分流造成的血流动力学的改变.使呼气末与动脉血二氧化碳分压差P(a-et)CO2]增大,给临床上通过呼气末二氧化碳分压(PETCO2)推测动脉血二氧化碳分压(PaCO2)带来困难.因此,如何正确地评估和预测PaCO2,避免过多地进行动脉血气分析是十分必要的.此文参考近年来的研究,对可能影响P(a-et)CO2值的各种因素作一综述.

| Abstract: | The pediatric congenital heart diseases are usually divided into cyanotic and non-cyanotic heart diseases. Due to the hemodynamic change caused by either left-right or right-left shunt, the value of arterial-to-end-tidal carbon dioxiede tension dif-ference (P(a- et)CO2) increases, which makes it difficult using pressure of end-tidal carbon dioxide (PETCO2) to predict pressure of arterial carbon dioxide (PaCO2). Therefore, in order to avoid excessive artery blood gas analysis, it is important to estimate and pre-dict PaCO2 exactly, especially in pediatric patients. The present review gathers various factors that probably influence P(a-et)CO2 and try to make a simple conclusion, based on published data recently. |
