肺栓塞时血气检查的诊断价值

DIAGNOSTIC VALUE OF BLOOD GAS EXAMINATION WHEN PULMONARY THROMBOEMBOLISM OCCURS

目的 提高血气分析对于诊断肺栓塞价值的认识。方法 对 32例PTE患者的血气检查结果进行回顾性分析。结果 32例PTE患者血气分析显示 :PaO2 降低的敏感性为 75 % ,PaO2 降低 +PaCO2 降低敏感性为 93 .4 % ,PaCO2 降低 +P <A -a >O2 升高的敏感性为 96 .9%。结论 PTE时动脉血气分析以PaCO2 降低和P <A -a>O2 升高为指标 。

Objective To better understand the value of blood gas analysis in diagnosing pulmonary thromboembolism. Methods Retrospective analysis was carried out about the result of the blood gas examination in 32 cases of PTE. Results The analysis of the PTE cases indicated that sensitivity of PaO 2 decrease was 75%; the sensitivity of PaO 2 decrease plus PaCO 2 was 93.4%, and the sensitivity of PaO 2 decrease plus P<A-a>O 2 increase was 96.9%. Conclusion When PaO 2 decrease and P<A-a>O 2 increase are taken as the main indexes for arterial blood gas analysis to diagnose PTE, the sensitivity of the diagnose can be improved.
