How Does Sodium Bicarbonate Correct Metabolic Acidosis

Share on facebook

Sodium Bicarbonate Use

metabolic acidosis leads to adverse cardiovascular effects bicarbonate must be administered in a solution as sodium bicarbonate 8.4% solution contains 1mmol of HCO3-/mL and is very hypertonic (2,000mOsm/kg) goal of NaHCO3 administration in severe metabolic acidosis to counteract the negative cardiovascular effects of acidaemia alternatives to NaHCO3 include carbicarb, dichloroacetate, Tris/THAM Treatment of sodium channel blocker overdose (e.g. tricyclic overdose) Urinary alkalinisation (salicylate poisoning) Metabolic acidosis (NAGMA) due to HCO3 loss (RTA, fistula losses) Cardiac arrest (in prolonged resuscitation + documented severe metabolic acidosis) Diabetic ketoacidosis (very rarely, perhaps if shocked and pH < 6.8) Severe pulmonary hypertension with RVF to optimize RV function Severe ischemic heart disease where lactic acidosis is thought to be an arrhythmogenic risk hypernatraemia (1mmol of Na+ for every 1mmol of HCO3-) hyperosmolality (cause arterial vasodilation and hypotension) impaired oxygen unloading due to left shift of the oxyhaemoglobin dissociation curve removal of acidotic inhibition of glycolysis by increased activity of PFK hypercapnia (CO2 readily passes int Continue reading >>

    Why does Ketoacidosis cause coma? How is it treated?




    1 Answer







    I’m assuming that you do know that ketoacidosis does not have to mean that you have high blood sugar. It means that you have a high level of ketones in your blood, which are usually by-products of your body trying to break down fatty acids for fuel it’s not getting from your food intake.
    It is usually treated with fluids, electrolytes, and insulin. It is much more common in those with type 1 diabetes then type 2, but it can still occur.

    You can look up more specific information on diabetes at the Mayo Clinic site.
