We review the FOAM from\\xa0SMACC GOLD, Dr. David Story\'s "Is Chloride A Poison?" for a great primer on the Stewart method to acid-base. \\xa0The Strong Ion Difference (SID) is essentially Sodium minus Chloride (Na - Cl). Normal = 38; a higher SID indicates metabolic alkalosis and a lower SID indicates a metabolic acidosis. \\xa0"Normal Saline" has a whopping amount of chloride, which decreases the SID and has been associated with acidosis, renal insufficiency in critically ill patients, and, perhaps, mortality.
