高危新生儿TcPO_2/TcPCO_2监测及与微量血气分析比较

TRANSCUTANEOUS PO_2/PCO_2 MONITORING IN HIGH RISK INFANTS

本文对50例高危新生儿进行TcPO_2/TcPCO_2监测,并与微量血气分析比较。发现TcPO_2/TcPCO_2分别与PaO_2/PaCO_2呈显著正相关。TcPO_2略高于PaO_2,而TcPCO_2明显高于PaCO_2。24例窒息和2例红细胞增多症新生儿校正TcPO_2与PaO_2比值增高,而4例严重贫血和3例重症肺炎使用Regitine者此比值显著下降。各种疾病情况下校正TcPOC_2与PaCO_2比值与总体均数无显著差异。新生儿血压、血红蛋白和血pH值与校正TcPO_2/PaO_2比值呈显著正相关,表明低血压、贫血和酸中毒可使TcPO_2下降。

Transcutaneous PO_2/PCO_2 monitoring (TcPO_2/TcPCO_2) was carried out in 50 high risk infants and compared with micromethod blood gas analysis (PaO_2/PaCO_2). The results showed that TcPO_2/TcPCO_2 had significantly positive correlation with PaCO_2/PaCO_2 (r=0.817 and 0.818, P<0.001). The average of TCPO_2 was slightly higher than that of PaO_2 (P>0.05), however the average of TcPCO_2 was remarkably high that of PaCO_2 (P< 0.001). Some diseases (asphyxia, erythrocytosis, severe anemia, pneumonia, etc.) exert certain influence on TcPO_2 monitoring, but litter on TcPCO_2. statistically significant correlation exists between blood pressure, hemogl- obin. PH and TcPO_2.
