摘　　要：52例危重病患者周围动脉和中心静脉血气酸碱平衡状态进行比较，提示正常心功能和轻度心衰患者，动静脉血气酸碱平衡状态无明显差异（P＞0．05）。重度心衰和循环衰竭患者，动静脉血气酸碱平衡状态出现明显分离现象。动脉血示低碳酸血症，而静脉血则反之，两者有明显差异（P＜0．05）。结果表明，重度心衰和周围循环衰竭患者，单纯监测动脉血血气，并不能反映组织内确切的酸碱状态，周围动脉血和中心静脉血必须同时进行监测。在严重低心排出量和低灌流病人，监测中心静脉血能较好地反映组织酸碱状态。Acid－base status between peripheral arterial and central venous blood gas analysiswere compared in 52 patients. It indicated that the acid－base status between peripheral arterial and central venous blood gas had no significant difference in patients with normalcardiac function or with mild cardiac failure, but there was a marked paradox between pesipheral arterial and central venous blood gas in the patients with severe cardiac and circulatory failure. Arterial blood showed hypocapnia but not the venous blood (P<0. 05).We concluded that the samples of central venous blood in addition to the arterial bloodshouId be required for the appropriate monitoring the acid－base composition in patientswith cardiac and circulatory failure－ The central venous blood gas is superior to the arterialblood gas in the assessment of the acid－base status in these patients.
