Drug-induced Metabolic Acidosis

Introduction Metabolic acidosis is defined as an excessive accumulation of non-volatile acid manifested as a primary reduction in serum bicarbonate concentration in the body associated with low plasma pH. Certain conditions may exist with other acid-base disorders such as metabolic alkalosis and respiratory acidosis/alkalosis1. Humans possess homeostatic mechanisms that maintain acid-base balance (Figure 1). One utilizes both bicarbonate and non-bicarbonate buffers in both the intracellular and the extracellular milieu in the immediate defense against volatile (mainly CO2) and non-volatile (organic and inorganic) acids before excretion by the lungs and kidneys, respectively. Renal excretion of non-volatile acid is the definitive solution after temporary buffering. This is an intricate and highly efficient homeostatic system. Derangements in over-production, under-excretion, or both can potentially lead to accumulation of excess acid resulting in metabolic acidosis (Figure 1). Figure 1. Excretion of acid and ways to jeopardize the system. 1. A strong non-volatile acid HA dissociates to release H+ and poses an immediate threat to plasma pH. 2. Bicarbonate buffers the H+ and generates Continue reading >>

    What are hyperkalemia and metabolic acidosis?




    1 Answer







    Hyperkalemia = high potassium levels in the blood. Commonly due to renal failure- kidneys not able to get rid of potassium so it builds up in your body. Hyperkalemia can be fatal because it causes heart arrhythmias including ventricular fibrillation.

    Metabolic acidosis is also a result of renal failure and is due to the kidneys not being able to excrete enough acid. Normally the pH of your blood is 7.35–7.45, so anything below 7.35 is considered ‘acidosis'. Metabolic in this case simply means caused by the kidneys, as opposed to ‘respiratory' acidosis which is due to airway obstruction and not being able to breathe out enough CO2

Explanation of the association between potassium and Acid base balance in the body.

On The Relationship Between Potassium And Acid-base Balance

The notion that acid-base and potassium homeostasis are linked is well known. Students of laboratory medicine will learn that in general acidemia (reduced blood pH) is associated with increased plasma potassium concentration (hyperkalemia), whilst alkalemia (increased blood pH) is associated with reduced plasma potassium concentration (hypokalemia). A frequently cited mechanism for these findings is that acidosis causes potassium to move from cells to extracellular fluid (plasma) in exchange for hydrogen ions, and alkalosis causes the reverse movement of potassium and hydrogen ions. As a recently published review makes clear, all the above may well be true, but it represents a gross oversimplification of the complex ways in which disorders of acid-base affect potassium metabolism and disorders of potassium affect acid-base balance. The review begins with an account of potassium homeostasis with particular detailed attention to the renal handling of potassium and regulation of potassium excretion in urine. This discussion includes detail of the many cellular mechanisms of potassium reabsorption and secretion throughout the renal tubule and collecting duct that ensure, despite signif Continue reading >>

Hyperchloremic Acidosis

Normal albumin-corrected anion gap acidosis Hyperchloremic acidosis is a common acid-base disturbance in critical illness, often mild (standard base excess >-10 mEq/L). Definitions of hyperchloremic acidosis vary. The best are not based on chloride concentrations, but on the presence of metabolic acidosis plus the absence of significant concentrations of lactate or other unmeasured anions. 2. standard base excess less than -3 mEq/L or bicarbonate less than 22 mmol/L, 3. Albumin corrected anion gap normal (5-15 mEq/L). A normal strong ion gap is an alternative indicator of the absence of unmeasured anions, although rarely used clinically and offering little advantage over the albumin corrected anion gap. The degree of respiratory compensation is relevant. It is appropriate if PaCO2 approximates the two numbers after arterial pH decimal point (e.g. pH=7.25, PaCO2=25 mm Hg; this rule applies to any primary metabolic acidosis down to a pH of 7.1). Acidosis is severe if standard base excess is less than -10 mEq/L, or pH is less than 7.3, or bicarbonate is less than 15 mmol/L. Common causes in critical illness are large volume saline administration, large volume colloid infusions (e.g. Continue reading >>
