摘　　要：碱剩余(BE)是临床血气分析中判断酸碱失衡的一个重要指标.一般认为BE负值增加为代谢性酸中毒.BE正值加大为代谢性碱中毒.不受呼吸因素影响.本文对94例肺心病患者的呼吸性酸中毒(呼酸)、代谢性碱中毒(代碱)、呼吸性酸中毒合并代谢性碱中毒(呼酸+代碱)共130例次血气检测中的BE值改变进行分析,就BE值改变的临床价值进行了初步探讨.1 资料和方法1.1 一般资料 94例均为住院病人.男70例,女24例.年龄31～87岁.平均64.75岁.1.2 方法 用国产康龄170型血气分析仪测定动脉血气,同步检测血清电解质,共130例次.将其结果按呼酸.呼酸+代碱、代碱分为相应的三个组,并对其BE值的改变进行对比分析.The base excess (BE) was analyzed in 130 blood gas analyses of 94 patients with pulmonary heart disease. The result shows that BE may be referred to as a metabolic index in clinical diagnosis of different types of acid-base disturbance,as actual bicarbonate (AB) was, and that BE affected by both metabllic and respiratory factors. Therefore it should be avoided that the metabolic alkalosis was decided by the increasing positive number of BE and the metabolic acidosis by raising negative number in clinical diagnosis.
