Podcast 503: Magical Magnesium

Podcast 503: Magical Magnesium

Contributor: Dylan Luyten, MD

Educational Pearls:

  • Those that are hypokalemic are often hypomagnesemic, and should receive magnesium (Mg) supplementation if repleting potassium
  • Mg levels are typically not necessary - if someone is suspect to have hypomagnesemia, just given them Mg
  • Mg increases the AV node refractory period and therefore may be helpful as an adjunct to those in atrial fibrillation with a rapid ventricular response
  • Mg is the preferred treatment for seizure prophylaxis in preeclampsia. All patients with suspected preeclampsia should get 4g Mg IV over 20 min
  • Mg may reduce hospital admissions in those with severe asthma, though it has not shown to have mortality or other benefits in acute exacerbations

Editor's note: and we didn't even touch on magnesium in headaches
