Question: Blood contamination of CSF

 34tor34 - Sun Dec 21, 2008 12:29 pm

What effects might be caused if someone's own blood (10-15ml) were accidentally injected directly into their CSF? how likely would complications be? Thanks for any assistance.

User avatar If you've already had your own blood (or if someone you know has) injected into your CSF (or that of whomever you might be speaking) and there have been no untoward effects til now, then there probably won't be. If you're considering doing this for some reason (I can't imagine why anyone would, but I also am having difficulty imagining how this could happen accidentally) I would strongly recommend against it because of the dangers inherent in breaching any access to natural CSF reservoir.

This has been done in laboratory studies, with mice, and for reasons other than to see what might happen due to the presence of blood cells. During these studies the actual presence of small amounts of blood cells in the CSF did not, in and of themselves, cause any problems. Much would depend on the amount of blood and if it were contaminated with anything at all, which would most likely be the source of any problem.

Hopefully this answers your question. Good luck to you.
