Management of metabolic acidosis pdf

As the individual loses their kidney function, renal excretion of nonvolatile acid produced by metabolism of the diet is impaired, resulting in lowgrade metabolic acidosis. The kidneys play an extremely important role in maintaining the body acidbase balance by excreting nonvolatile acids and regenerating and reabsorbing bicarbonate in the kidney tubules. Management of metabolic acidosis metabolic acidosis is caused by either the loss of hco 3or the net addition of strong acids. If you dont restore the right acidbase balance, it can affect your bones, muscles, and kidneys. Decisions about the type of therapy also depend on the duration and. Acute forms of metabolic acidosis most frequently result from the overproduction of organic acids such as ketoacids or lactic acid. This section is a brief discussion of the metabolic aspects of acidbase balance. Abg will also judge the appropriateness of respiratory compensation of a metabolic acidosis. Metabolic acidosis is an acidbase imbalance resulting from excessive absorption or retention of acid or excessive excretion of bicarbonate produced by an underlying pathologic disorder. Metabolic acidosis can lead to acidemia, which is defined as an arterial blood ph lower than 7.

Its metabolic variety is characterized by an initial decrease in plasma bicarbonate concentration hco 3 in a setting of a history and physical examination supportive of this diagnosis. Understand the clinical approach to acidbase disorders, including the basic equation, questions to ask about each disorder, the use of venous electrolytes, arterial blood gases, and the acidbase. Symptoms of metabolic acidosis can include nausea, vomiting, and extreme tiredness. Unusual dlactic acid acidosis from propylene glycol metabolism in overdose. Metabolic acidosis is a disorder frequently encountered in emergency medicine and intensive care medicine. Symptoms result from the bodys attempts to correct the acidotic condition through compensatory mechanisms in the lungs, kidneys and cells. Beginning with a basic understanding of the physiology, pathophysiology and development of this disease, subsequent chapters cover the characteristics and context of the processes that can cause it and a thorough presentation of management. Acidosis is defined as an arterial ph below the normal range acidosis. Management of ventilation, which controls the respiratory component of acidbase balance, is discussed in the section on respiratory support p. The elimination or control of the underlying cause, if feasible, is obviously a high priority in the treatment of all forms of metabolic acidosis. Metabolic acidosis in adults is discussed separately. Clresistant metabolic alkalosis is due to increased aldosterone effect so management involves the correction of hyperaldosteronism.

Guidelines for the management of metabolic alkalosis by dr. Treatment depends on the cause of metabolic acidosis, which makes your blood too acidic. Metabolic alkalosis involving loss or excess secretion of cl is termed clresponsive managed by treating the cause and give patients with clresponsive metabolic alkalosis 0. Metabolic acidosisacute or chroniccan have considerable adverse effects on cellular function and can contribute to increased morbidity and mortality.
