[Clinical aspects of acid-base disorders].

ABSTRACT

Acid-base disorders are frequently recognized in a wide variety of clinical settings such as severe systemic hospitalized patients. The principal object is to assessment of acid-base equilibrium and to obtain an appropriate guide to therapy. The approach is centered to a systemic analysis of blood gas evaluation. To establish this complex matter is followed. Is an acid-base disorder present? Is the disorder a simple or a mixed abnormality? What is the primary cause? These evaluations should be obtained by accurate history taking, physical examination, and routine laboratory tests. In addition, the supporting analysises such as anion gap (AG) calculation, urine AG assessment, urine chloride concentration and so on are also useful for correct diagnosis. In view of the complexty and difficult expression of acid-base disorders, it is desirable that clinicians must have full knowledges of systemic approach to the blood gas analysis and its evaluation.
