动脉血O_2,CO_2分压的测量,过去一直需要直接动脉采血进行测量,其所受影响的因素很多,结果往往不能真实地反映实际水平。经皮肤测量O_2CO_2分压是80年代应用于临床的新技术,我们利用经皮肤测最的O_2分压(tcPO_2)、CO_2分压(tcPCO_2)来推算肺内分流率(Qs/Q_T)以了解肺炎的病变性质、程度,指导治疗和判断预后,现总结如下。材料和方法一、监测对象对1986年12月～1987年3月住院的新生儿室患儿共44例,分别测量tcPO_2、tcPCO_2、Hb,设肺炎组和对照组各22例。对照组新生儿已排除呼吸系统疾患,其中有硬肿症7例,败血症5例,黄疸6例,脐炎2例,低钙抽搐1例,早产儿1例。
Arterial O_2, CO_2 partial pressure measurement, the past has been the need for direct arterial blood sampling, which affected many factors, the results often can not truly reflect the actual level. Percutaneous measurement of O 2 CO 2 partial pressure was a new clinical technique applied in the 1980s. We estimated the intrapulmonary shunts (Qs / Q_T) by using the most sensitive O 2 partial pressure (tcPO_2) and CO 2 partial pressure (tcPCO_2) The nature of the disease, degree, guide treatment and prognosis, are summarized as follows. Materials and methods First, the monitoring object of December 1986 ~ March 1987 hospitalized neonatal room a total of 44 children were measured tcPO_2, tcPCO_2, Hb, set the pneumonia group and the control group of 22 patients. Neonatal control group had ruled out respiratory diseases, including 7 cases of sclerema, 5 cases of sepsis, 6 cases of jaundice, 2 cases of omphalitis, convulsions in 1 case of low calcium, 1 case of premature children.
