Hyperkalemia Management: Preventing Hypoglycemia From Insulin
Insulin remains one of the cornerstones of early severe hyperkalemia management. Insulin works via a complex process to temporarily shift potassium intracellularly. Though insulin certainly lowers plasma potassium concentrations, we often underestimate the hypoglycemic potential of a 10 unit IV insulin dose in this setting. The purpose of this post is to highlight the need for proper supplemental glucose and blood glucose monitoring when treating hyperkalemia with insulin.
This is such an important medication safety issue, the Institute for Safe Medication Practices (ISMP) highlighted it in a February 2018 Safety Alert.




Patients with acute salicylate toxicity can rapidly decompensate and require clinicians to understand the pathophysiology of what is going on. First a respiratory alkalosis occurs with non-specific symptoms of vomiting and dizziness. Then an anion-gap metabolic acidosis also occurs with headache, tinnitus, and confusion.
