Normal Saline Intoxication - Deranged Physiology
Uncontrolled pancreatic secretions as a cause of acidosis The overzealous administration of sodium chloride causes a normal anion gap metabolic acidosis by decreasing the strong ion difference. This is the archetypal normal anion gap acidosis. Previously discussed calculations suggest that every bag of saline increases the serum chloride by 3mmol/L. In Stewarts terms, normal saline has a strong ion difference of 0mmol/L (given how equal the concentrations of sodium and chloride are), and thus adding it to a body fluid will decrease the strong ion difference. The strong ion difference of Hartmanns, on the other hand, is 28mmol/L, and so it has a much gentler acidifying effect. This has been demonstrated experimentally in a cohort of 5 septic patients; and the theory is discussed in detail here . Change in strong ion difference following the infusion of normal saline The above graph is adopted from Lobo et al, who in 2003 infused a series of healthy volunteers with 2000ml of normal saline to study the difference between sodium chloride and Hartmanns solution. Now, enough saline-bashing. If we remain faithful to the interpretation of acid base disorders in terms of the strong ion dif

Is Correcting Hyperchloremic Acidosis Beneficial?
You are here: Home / PULMCrit / Is correcting hyperchloremic acidosis beneficial? 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
Nephron Power: Consult Rounds: Why Does Infusion Of Normal Saline Cause Metabolic Acidosis?
Consult Rounds: Why does infusion of normal saline cause metabolic acidosis? Why does infusion of normal saline cause metabolic acidosis? This should be an easyanswer but when you review the literature, the literature is all over theplace( literally!!).Collection of responses I received when I asked few expertsin the field: 1. Thebicarbonate ions are diluted bythe isotonic fluid,and acidosis occursas a result. 2. The fall in serum bicarbonate is dueto the expansion of the extracellular fluid volume withlarge IV fluids 3. The "strong ion difference" (SID) helpsexplain this that in order to maintain electroneutrality. Since there is diluting fluid, water must dissociate, providing excess protons which leads to metabolic acidosis. - via the stewart method of acid base 4. Usually 60% of the filtered bicarbonate load isreabsorbed in euvolemia. When extracellular volume is low the proximaltubular absorption is increased, maybe to 80%,due to changes in oncoticpressure and hydrostatic pressure of peri tubular capillaries and glomerulus.This results in increased reabsorption in setting of volume depletion.When extracellular volume is increased then proximal tubular absorptionof bicarbonate

Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. The SID (Strong Ion Difference) is the difference between the positively- and negatively-charged strong ions in plasma. This method of evaluating acid-base disorders was developed to help determine the mechanism of the disorder rather than simply categorizing them into metabolic vs. respiratory acidosis/alkalosis as with the ...
