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）CO：2]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。
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 difference （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 predict 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.
