Trick of the Trade: Sodium Bicarbonate for Acute Symptomatic Hyponatremia

A 25-year-old woman is brought into the emergency department by friends due to “acting weird.” She was at a rave and is reported to have consumed alcohol, marijuana, and ecstasy. On exam, she is afebrile, tachycardic, normotensive, and breathing comfortably on room air. She is lethargic, mumbling incomprehensibly, and does not follow commands. Her glucose is 115 mg/dL, her pregnancy test is negative, her EKG reveals sinus tachycardia, her ethanol level is 30 mg/dL, and a stat CT head is negative. Her chemistry panel reveals a sodium level of 114 mEq/L. You order a 100 mL 3% sodium chloride bolus, but it may take 30 minutes to arrive from the central pharmacy. At this point, the nurse informs you that the patient is seizing.


Emergency Medicine (EM) physicians care for anyone, with anything, at any time. This includes pediatric patients as well as adults. For those without advanced pediatric training, “sick kids” can be quite intimidating. Rashes in the pediatric population are often benign, but in rare cases they portend significant illness. Rashes are also frequent chief complaints; In 2015, there were 1,452,300 pediatric ED visits for “skin and subcutaneous tissue disorders” [1]. We sought to improve the teaching of pediatric rashes in our residency curriculum.
