Disclaimer Notice:

Dear Readers! I started this blog when my daughter was in the NICU. She had ventriculitis. Her CSF report grew E.coli. But, she was injected Teicoplanin directly into her brain. The doctors made two errors here:

Teicoplanin is for gram-positive bacteria only. It does not treat E.coli.
Teicoplanin is not for intraventricular use. The manufacturer strongly discourage injecting Teicoplanin into the brain.

My daughter bled into the brain. She lived for another two years and ultimately died.
