Dylan is having surgery this afternoon to close his PDA. It's supposed to be relatively simple, but it's still surgery.
I know all of the risks but also have faith thy it'll be fine. The surgeon is really good and I am confident that he will do a good job.
Please keep Dylan in your thoughts. I will update when things are calm, but please do not take a few days silence to mean that anything is wrong.
Everything went really well. Hopefully now he'll be able to get off the vent soon.
