Chemo went well. It took a while to get started, so she finished the 24 hour infusion at midnight. No side effects right now.
Tuesday, Scarlett underwent an extensive evoked-response hearing test. She was sedated, then brain waves were measured as different ranges of sounds were presented. It took over two hours for the procedure; I got a chance to wander the mall a bit and get some fresh air while I waited. When I returned, the audiologist had some bad news: Scarlett has mild to moderate hearing loss in both ears. Her left ear is slightly worse than the right. There has been some discussion of fitting her for hearing aids. Not the worst thing we have faced, but yet another challenge for our sweet baby girl to overcome.
Two months ago, we had a preliminary hearing test that showed no deficits; her hearing was unaffected by the tumor and surgery. We knew that one of the chemo drugs was ototoxic (hearing-damaging), but our doctors felt it was the best option. We learned that the antibiotic used to treat her shunt infection can also have ototoxic effects. The infection itself may also be a contributing factor. There is not really any way to know what caused it, nor how much hearing will be regained as the medications are changed or removed.
We've been in the hospital for 18 days and counting, our second-longest stay. We have to stay at least until the current chemo clears her system, which usually takes 4-5 days. Then we run right into her next dose; if she takes an extra day to clear, we will just stay on through. If she clears earlier, we will go home for a few days before being readmitted.
