I wondered this too. I worried that our clinic, specifically our dietician (who is probably reading this...*waves*) were trying to improve thier "numbers." Since this whole "Cfer's do better when they are at or above the 50th percentile concept is relativley new, and, I beleive, is one of the standards by which clinics are measured, I was convinced that the g-tube was being pushed for reasons other than Emily's best interest.
I called two other clinics, who of course could tell me nothing about what they'd reccomend for Emily without actually seeing her and knowing her history. Both did tell me that they were reccommending g-tubes for more and more young patients every year, simply because patients did SO well with them. The best thing I got out of my calls to the other clnics, though, was the Nurse at one of the clinics who said, "YOU are in control of this decision. You do not have to do this until you are ready. This is, medically, the best option, but it is not life or death, and waitng six months until youy are sure will not hurt her." Now, after hearing that I felt like the pressure was off and I could think rationally, not emotionally. That's when I had the epiphny I've already described to you.
One more thing to consider, and, knowing me, I've told you this already, too. (I have no self-control when it comes to the length of my responses) I wondered why another CF'er who was treated AT our clinic, BY our pulmo and team, who was a month OLDER than Emily and weighed LESS was not being "pushed" in the direction of a tube. THe mom of the other kid and I had been corresponding via e-mail for some time, so I knew that we were definately being steered in that direction more forcefully than they were. So, I asked about it. Again, it was sort of an epiphianny moment. The pulmo asked if I taught every kid to read in exactly the same way. Of course not. They all need to learn to do it, but I use at least half a dozen different approaches. Their personality, the ability of the parent to support them at home, thier style of learnig, their innate ability level...it all factors in. I have to play around a bit to figure out what works, and some of it is just "gut feeling." Well, said the pulmo, PROACTIVE medicine, (as opposed to REactive medicine) is a lot like that. Her gut instinct was that the g-tube was best for Emily at this point in time.
Incidentally, 2 months after Em got her tube, the other little girl's family visited us at home so they could get an idea of how the tube and pump worked. They were getting theirs the next week. Both of the girls have had success with them.
I know that you know that I have no regrets about our decision. But, I also want you to know that I think the questioning you are doing is normal, and healthy. You are Alyssa's advocate. You are the one who will be doing the feedings. If you aren't ready, wait. You can reverse your decision to NOT get it right now, but you really can't reverse your decision to get it.
Good luck, and please call or PM if you need to. I'll be thinking of you.
