Approach To The Adult With Metabolic Acidosis
INTRODUCTION On a typical Western diet, approximately 15,000 mmol of carbon dioxide (which can generate carbonic acid as it combines with water) and 50 to 100 mEq of nonvolatile acid (mostly sulfuric acid derived from the metabolism of sulfur-containing amino acids) are produced each day. Acid-base balance is maintained by pulmonary and renal excretion of carbon dioxide and nonvolatile acid, respectively. Renal excretion of acid involves the combination of hydrogen ions with urinary titratable acids, particularly phosphate (HPO42- + H+ —> H2PO4-), and ammonia to form ammonium (NH3 + H+ —> NH4+) . The latter is the primary adaptive response since ammonia production from the metabolism of glutamine can be appropriately increased in response to an acid load . Acid-base balance is usually assessed in terms of the bicarbonate-carbon dioxide buffer system: Dissolved CO2 + H2O <—> H2CO3 <—> HCO3- + H+ The ratio between these reactants can be expressed by the Henderson-Hasselbalch equation. By convention, the pKa of 6.10 is used when the dominator is the concentration of dissolved CO2, and this is proportional to the pCO2 (the actual concentration of the acid H2CO3 is very lo

Types Of Disturbances
The different types of acid-base disturbances are differentiated based on: Origin: Respiratory or metabolic Primary or secondary (compensatory) Uncomplicated or mixed: A simple or uncomplicated disturbance is a single or primary acid-base disturbance with or without compensation. A mixed disturbance is more than one primary disturbance (not a primary with an expected compensatory response). Acid-base disturbances have profound effects on the body. Acidemia results in arrythmias, decreased cardiac output, depression, and bone demineralization. Alkalemia results in tetany and convulsions, weakness, polydipsia and polyuria. Thus, the body will immediately respond to changes in pH or H+, which must be kept within strict defined limits. As soon as there is a metabolic or respiratory acid-base disturbance, body buffers immediately soak up the proton (in acidosis) or release protons (alkalosis) to offset the changes in H+ (i.e. the body compensates for the changes in H+). This is very effective so minimal changes in pH occur if the body is keeping up or the acid-base abnormality is mild. However, once buffers are overwhelmed, the pH will change and kick in stronger responses. Remember tha

Is Correcting Hyperchloremic Acidosis Beneficial?

An elderly woman presents with renal failure due to severe dehydration from diarrhea. She has a hyperchloremic acidosis from diarrhea with a chloride of 115 mEq/L, bicarbonate of 15 mEq/L, and a normal anion gap. During her volume resuscitation, should isotonic bicarbonate be used to correct her hyperchloremic acidosis? Does correcting her hyperchloremic acidosis actually help her, or does this just make her numbers better? The use of bicarbonate for treatment of metabolic acidosis is controversial. However, this controversy centers primarily around use of bicarbonate for management of lactic acidosis or ketoacidosis.Treatment of these disorders requires reversing the underlying disease process, with bicarbonate offering little if any benefit.Hyperchloremic metabolic acidosis is different.Whether due to bicarbonate loss or volume repletion with normal saline, the primary problems is a bicarbonate deficiency.Treating this with bicarbonate is a logical and accepted approach: Giving bicarbonate to a patient with a true bicarbonate deficit is not controve

SUMMARYFirst, do no harm. These words have been the doctrine of medicine since its inception. The era of evidence-based medicine now compels us to provide scientific evidence that we indeed do no harm and that the treatments we prescribe have a beneficial effect. The colloid/crystalloid debate continues to evolve and is as hotly contested now as it was a decade ago. There may be some international differences in the use of colloids or crystalloi ...
