| 摘 要： | 目的评估血气分析在急性肺血栓栓塞症诊断的作用。方法回顾性分析43例既往无心肺疾病的急性肺栓塞患者动脉血气结果。结果43例急性肺血栓栓塞症患者血气分析显示：PaO2降低的敏感性为81.40%;PaCO2降低的敏感性为69.77%;P（A-a）O2升高的敏感性为88.37%;当两个指标综合考虑时,PaO2降低或PaCO2降低的敏感性为90.70%;PaO2降低或P（A-a）O2升高的敏感性为95.35%;P（A-a）O2升高或PaCO2降低的敏感性为97.67%;1例P（A-a）O2和PaCO2均正常者。结论PaCO2和P（A-a）O2均正常可作为排除急性肺栓塞的重要依据。 |

| Abstract: | Objective To evaluate the diagnostic value of arterial blood gas analysis in acute pulmonary thromboembolism. Methods Retrospective analysis was performed for arterial blood gas in 43 patients with pulmonary thromboembolism who had no prior cardiopulmonary disease. Results The sensitivity of PaO2 decrease was 81.40%. Either a decreased PaO2 or a decreased PaCO2 was observed in 39 of 43 ,with a sensitivity of 90.70 %. Either a decreased PaCO2 or increased P（A-a）O2gradient was observed in 42 of 43 ,yielding a sensitivity of 97.67 %.Only one patient had normal PaCO2 and P（A-a）O2 gradients. Conclusion Normal PaCO2 and P（A-a）O2 gradients can be used as evidence to rule out acute pulmonary thromboembolism. |
