摘要
对70例急性加重期肺心病及13例肺性脑病患者同时作动静脉血气分析,并与60例慢性支气管炎和29例正常人对比,结果发现:(1)肺心病急性加重期动静脉氧分压差(△PO_2)显著低于慢支炎及正常人,而以肺性脑病时最低(P<0.01～0.001);(2)肺心病急性加重期动静脉血pH值差(△pH)显著低于正常人,肺性脑病时尤显著(P<0.01),而动、静脉血〔HCO_3~ˉ〕和BE差值无显著性(P>0.05);(3)影响△PO_2的因素有PaO_2和PaCO_2;影响△pH的主要因素为△PO_2。
Blood gas analyses of arterial and venous blood were carried out simultaneously in pa-tients with 70 CCP, 13 pulmonury enceph. lopathy (PE) and 60 chronic bronchitis and 29 do-nor. Theresults showed there are notable significances in arteriarvenaus differenes(△) of PH PCO_2 PO HCO_3^- and in far each group except HCO_3^- and BE in PE, and there are alsa shgnificant differances in arteral-venous oxygen teasnon differences(△PO_2) between each two groups(p<0.01-0.001). In patients with CCP of acute exacerbation, arterial PH, PO_2 and △PO_2 decresed gradually and △HCO_3^- inereased with increased arterial carbon dioxide. The results suggested that it is helpful to understand tissure oxygen supply and patients acis-b-ase condi-tion, but also it is helpful to analys is peripheral circulative perfsion condition and regulating ability of humen body to acid-base disorder when the matched pairs of arterial and venous blood of blood gas analyses were done.
