Mixed acid-base disorders, the occurrence of two or more primary acid-base disturbances in the same patient, are common in the hospital population, but are usually misdiagnosed because of lack of knowledge of the consequences of the primary disturbances. This paper describes seven examples of these disorders recently seen in the authors' hospital, and provides a logical approach to their diagnosis. Most users should sign in with their email address.

The simultaneous presence of two or more acid-base disturbances produces the conditions known as mixed acid-base disorders. Characterization of these disorders and proper identification of their pathogenesis can be a challenging task and is a prerequisite for taking sound corrective action 1—5. Such therapeutic measures might be of critical importance because many mixed acid-base disorders confer high morbidity and mortality. Furthermore, mixed acid-base disturbances are commonly observed in hospitalized patients, especially those in critical care units. Moreover, under certain circumstances, detection of a mixed acid-base disorder might provide a clue to the presence of a previously unrecognized disease. Unable to display preview.

The authors describe the pathophysiological mechanisms leading to development of acidosis in patients with chronic obstructive pulmonary disease and its deleterious effects on outcome and mortality rate. Renal compensatory adjustments consequent to acidosis are also described in detail with emphasis on differences between acute and chronic respiratory acidosis. Mixed acid-base disturbances due to comorbidity and side effects of some drugs in these patients are also examined, and practical considerations for a correct diagnosis are provided.

Although this is traditionally considered a mandatory component of pH analysis, the amount of useful information provided by this analysis is unclear. Blood gas analysis can answer essentially two questions:. Generally, the most critical aspect of pH analysis is to identify unexpected diagnoses 1. The precise severity of the disorder is less important. As long as we have correctly identified the underlying diagnosis and we are treating it appropriately, the exact pH numbers are often relatively unimportant.

A practical approach to acid-base disorders.

Virtually all recent discussions of the diagnosis and management of mixed acid-base disturbances have focused exclusively on the acid-base disorders per se and have relegated the patient and the clinical setting to a subordinate position. In the s several excellent reviews utilizing primarily a laboratory approach have appeared 1—3. In this laboratory-dominated approach, the acid-base data first are examined to determine whether they are consistent with any of the simple acid-base disorders; if the acid-base data do not fit, and assuming that they reflect a steady state, one can confidently conclude that a mixed acid-base disturbance is present 4.

The trouble is that for all the intellectual endeavour, little original insight is usually added to the leadership debate.
