本组40例均经临床确诊为慢性肺源性心脏病,年龄60～79岁,平均68.4岁。既往有慢性支气管炎10年以上者16例,20年以上者24例。肺源性心脏病(肺心病)5年以上者8例,10年以上者20例。本组大多数患者在住院期间应用利尿剂,肾上腺皮质激素及大量葡萄糖输液,部份患者使用呼吸兴奋剂或呼吸器等治疗。仪器采用国产DH-100G 型血气酸硷分析仪,使用选择性离子电极直接测定。用2ml 空针筒肝素化,采取患者动脉血1.5～2ml,密封标本,5～10分钟内测得pH、PaO_2、PaCO_2三个基本参数,每份标本重复3次,重复性在允许
The group of 40 patients were clinically diagnosed as chronic cor pulmonale, aged 60 to 79 years, mean 68.4 years. Previous chronic bronchitis in more than 10 years in 16 cases, more than 20 years in 24 cases. Pulmonary heart disease (pulmonary heart disease) more than 5 years in 8 cases, more than 10 years in 20 cases. Most patients in this group during diuretics, adrenal cortical hormone and glucose infusion, some patients with respiratory stimulants or respirators and other treatment. Instrument using domestic DH-100G blood gas pH analyzer, the use of selective ion electrode direct determination. With 2ml hollow needle heparinized, take the patient arterial blood 1.5 ~ 2ml, sealed specimens, 5 to 10 minutes measured pH, PaO_2, PaCO_2 three basic parameters, each specimen was repeated 3 times, the repeatability is allowed
