P_(ET)CO_2监测在胸段硬膜外麻醉病人中的应用

The application of monitoring P_(ET) CO_2 to the patients during thoracic epidural anesthesia

目的 为了评价胸段硬膜外阻滞中经鼻导管至咽后壁监测PETCO2 的必要性和准确性。方法 对 2 8例上腹部手术病人胸段硬膜外阻滞过程中各时相点PETCO2 和PaCO2 的变化 ,以及两者之间的相关性进行观察。结果 麻醉中PaCO2 和PETCO2 增高有显著性意义 (P <0 .0 1) ;PETCO2 和PaCO2 两者之间呈正相关 (r =0 .814 ,P <0 .0 0 1) ,PETCO2 能真实反映PaCO2 值。结论 鼻插管至咽后壁监测PETCO2 方法简单、易行、无创 ,建议将PETCO2

Objective To evaluate the necessity and accuracy of monitoring P ET CO 2 during the thoracic epidural anesthesia.Methods The variety and relativity of P ET CO 2 and PaCO 2 in every time for 28 cases,which were operated in thoracic epidural anesthesia of midsection,were observed.Results With hightened P ET CO 2 and PaCO 2,there was significant difference in anesthesia.And there was positive correlation between two values.The value of PaCO 2 could be expressed P ET CO 2 truly.Conclusion The monitoring P ET CO 2 can be a routine of thoracic epidural anesthesia.
