C had a sleep study last night. His dentist recently mentioned that he had large tonsils. We saw ENT shortly after that to follow up on his tubes falling out, and she agreed that his tonsils were large. He does snore at night, but not generally enough to concern me. At the time, we agreed that a sleep study might be helpful, but not urgent. Last week, however, I was talking to a colleague who is a pediatrician, and he mentioned sweating as a sign of sleep apnea, which C does often. And he mentioned that sleep apnea is associated with right ventricular hypertrophy, which of course concerned me for a kid who only has a right ventricle. I ended up calling ENT back, and they agreed it would be good to do the sleep study. So, he started off great, tolerated all the stickers and wires really well, and fell right asleep with me. Two hours later, they came in and said his sats were dipping into the 70s, even with oxygen on, and they wanted him on CPAP for the rest of the night. He did OK with it, and did really well while it was on, but he did wake up several times scared, so we turned it off and then back on a few times. At this point we'll wait to see what the sleep study physician says, then ENT, and possibly cardiology. His baseline sats are in the mid 80s, so the sat drops alone don't concern me (his target is above 75), but I don't know if he was having actual apnea episodes or just hypoxic episodes. If it is apnea, we'll likely have a choice of CPAP or T&A surgery, and we'll likely go with surgery, even though that's more complicated for him. I can't imagine lifetime CPAP.
