Hyponatremia and Central Pontine Myelinolysis

What is hyponatremia? Information regarding CPM and EPM.

Hyponatremia: Children

I know I’ve mentioned that children are at risk for hyponatremia, but this is a growing epidemic.

Here’s the thing: children can be at great risk because when they go to a hospital for treatment they receive a general IV which is usually lacking in sodium. When this happens, a child’s blood sodium level becomes diluted to point of hyponatremia.

At this point the child’s brain begins to swell and their brain is larger at this point compared to the size of their skull VS that of an adult. In other words, a child’s brain is fully developed at 6, but their skull doesn’t become fully developed until around age of 16. This gives a child’s brain less room to expand, and so they are more likely to develop injury.

Use the following link to find out more:


It is suggested in this article that a child should be given IV fluids containing .9% saline whenever treated in the hospital. This includes ER visits.

Because the early symptoms of brain swelling are common symptoms of nausea, headache, vomiting and lethargy. This article suggests that their blood sodium levels be checked at the presentation of these symptoms.

I’m not sure what it is with me tonight, but I’m at a point of loss right now. I just can’t concentrate fully. The article I have cited above contains extremely pertinent information for the treatment and prevention of hyponatremia in children. It is also a recent article from 2010.

I highly recommend if you have a child who is in the hospital who is being treated for any disorder, make a copy of this article and go over it with your pediatrician or your treating physician.

At some point in the future, I will attempt to edit the post to a more complete form, but I really find that the information itself is important enough to publish even in this rough draft form.

May you never need to use it personally.
