hello, I'm sorry your friend is going through so much. I don't have CF but my son does. I have no idea what your friend's prognosis is but don't get too discouraged, getting a central line is not necessarily a bad thing. I don't have CF, but I had a central line put in my chest(I have crohn's disease and my veins were so scarred and weak that a central line was my only choice) I was horrified at the thought of having this put in, but it was actually a good thing. I was mildly sedated and they put a local anesthetic in my skin right below my collarbone. the central was put in, yes it hurt pretty bad, but it was over in a few minutes. Once the procedure was over I was so happy that I done it; no more digging in my arms (and even my feet) to find a vein good enough to put an IV in, no more burning in my veins when they put strong drugs into my IV, and I could actually use both of my hands!! I'm positive that this Central line will be a good thing for your friend and it will help him to heal better. It is not a way of giving up or that he will have to IV meds for the rest of his life, it is just going to make getting the meds easier to deal with. I had my central line removed before I had my son and I wished I had it when I was in labor with my son (It took 10 sticks and two failed IV's to get my drugs--and they still ended up putting an IV in my ankle!!!
On another note, visit your friend in the hospital as much as you can. Being in the hospital over the holidays is no fun. Talk to him and let him know that you will be there for him always, no matter what. Be there for his mom, as well. She is probably extremely stressed out and needs some TLC as well. When my son is sick and his friends still visit him it is truly a gift---to see him having fun and playing with friends that are not threatened by the tubes and treatments---that lifts my spirits like nothing else. If you support your friend and comfort his mother, no matter what happens, you will forever be an amazing experience his life and his family's life. Just because you are a teenager doesn't mean you can't help (definitly more so than the adults who send stinky bouqets of flowers rather than call or visit!!!!!) Hang in there, I hope that when my son is 16 he will have a friend as caring and generous as you. Good Luck!
