Abstract

In 12 newborns combined transcutaneous PO2 and PCO2 levels were measured by means of a Sensor Medics Transend Transcutaneous Gas System simultaneously with the end-tidal PCO2 (PetCo2) values using an Angström Eliza CO2 analyzer. Although the individual correlation coefficients differed greatly, the diagnostic sensitivity of PtcO2 and PtcCO2 was satisfactory within specified limits. The PetCO2 did not agree well with the PaCO2 due to physiologic factors related to lung disorders. We conclude that PtcO2 and PtcCO2 values are very useful in monitoring severely ill newborns although arterial blood gas measurements remain necessary, but not as often as when the transcutaneous technique is not used.

摘要

采用Sensor Medics Transend经皮气体系统，同时使用安斯特朗伊莱扎二氧化碳分析仪测量12例新生儿的经皮氧分压（PO2）和二氧化碳分压（PCO2）水平以及呼气末二氧化碳分压（PetCo2）值。尽管个体相关系数差异很大，但在规定范围内，经皮氧分压（PtcO2）和经皮二氧化碳分压（PtcCO2）的诊断敏感性令人满意。由于与肺部疾病相关的生理因素，呼气末二氧化碳分压（PetCO2）与动脉血二氧化碳分压（PaCO2）不一致。我们得出结论，经皮氧分压（PtcO2）和经皮二氧化碳分压（PtcCO2）值在监测重症新生儿方面非常有用，尽管动脉血气测量仍然必要，但频率不像不使用经皮技术时那么高。
