混合性酸碱失衡是指同时在同一患者身上存在两种或两种以上的单纯性酸碱失衡。这些酸碱失衡的病理生理过程对血液的PH影响既可十分严重,也可能使PH在正常范围,如代谢性酸中毒(简称代酸),合并呼吸性酸中毒(简称呼酸),PH降低十分明显,造成严重的酸血症;代谢性碱中毒(简称代碱)合并代酸,PH可以正常,既非酸血症。也不是碱血症。临床病例我们选择病例5则,将有关临床资料(病情摘要、临床诊断、电解质和血气值)列表如下(表1、表2),以便在讨论中对每例酸碱失衡诊断加以分析,以阐明混合性酸碱失衡的诊断经过。
Mixed acid-base imbalance refers to the same patient in the same time there are two or more simple acid-base imbalance. These acid-base imbalance pathophysiological processes on the blood PH can be very serious, but also may make the PH in the normal range, such as metabolic acidosis (referred to as acid), combined respiratory acidosis (referred to as acid), PH decreased Very obvious, causing severe acidosis; metabolic alkalosis (referred to as alkali) combined with acid, PH can be normal, neither acidosis. It is not alkalosis. CLINICAL CASE We selected Case 5 and listed the clinical data (summary of illness, clinical diagnosis, electrolytes and blood gas values) as follows (Table 1, Table 2) to analyze each case of acid-base imbalance diagnoses in the discussion to clarify Mixed acid-base imbalance in the diagnosis.
