摘要
本组测定５０例肝硬化患者动脉血气、并同时测Ｒ８Ｃ计数及Ｎｂ量的变化.结果动脉低氧血症３３例占的６６％.动脉血氧分压（ＰａＯ_２）在慢性肝性脑病（ＨＥ）组降低明显，与有上消化道出血（ＵＧＩＢ）组及无ＨＥ亦无ＵＧＩＢ组相比，差异显著.ＲＢＣ计数及Ｈｂ量在ＵＧＩＢ组最低，提示动脉低氧血症的发生与多种因素有关.在急性ＵＧＩＢ时，患者对缺氧的耐受性下降，ＲＢＣ数、Ｈｂ量的迅速降低可很快诱发ＨＥ.
Arterial blood一gas assay, red blood cell(RBC)count and haemoglobin(Hb) levelwere determined in 50 patients with hepatic cirrhosis.33 patients were found with arterial hy-poxaemia (66%). Arterial blood oxygen partial pressure (PaO2)decreased more obviously in thegroup with hepatic encephalopathy(HE)than those without HE or only with upper gastrointestinaltract bleeding (UGIB).RBC count and Hb level were the lowest in group of UGIB。 It is sugg-ested that the many factors may be responsible for arterial hypoxaemia。The decrease of RBC countand Hb level may not be important. However in the cases with acute UGIB,the rapid decreaseof RBC and Hb level may result in HE because patient’s resistance to hypoaemia was reduced 。
