I have a backlog of posts about CNS prophylaxis side effects, kidney stones, a nephrolithotomy, and hospital staff. Hopefully I will get around to those soon!Today is Mama Pham's fifth CNS Prophylaxis. I have written about this procedure in the past. It is chemo that is inserted into the spine as preventative measure. Leukemia cells can infiltrate the Central Nervous System, but normal chemo cannot. Therefore, oncologists take preventative measures and insert chemo directly into the spine. While doing so, they first draw some spinal fluid to test for irregularity. The process of puncturing the spinal tissue and drawing fluid often causes patients to get extreme headaches because of the depletion of fluids around the brain. This can be remedied with drinking fluids or getting fluids through IV. However, if there is a leak at the puncture point, spinal fluid continues to leak into the body, causing continuous fluid depletion around the brain. That causes continuous headaches, nausea, dizziness and neck pain that cannot be remedied by much, not even strong pain medications. The leak is caused by the body's inability to quickly heal the wound.She has had very different reactions to the past four procedures. Here's to a successful, pain-free, headache and nausea free Lumbar Puncture!
