A few days ago, Emma had a big attack in hospital. She had 2 nebs with time in between and got worse with her condition. She had another 6 nebs back to back, and this seemed to sort her asthma out. The doctors who were around at the time mentioned about getting an IV line going with some sort of medication, Emma is against IV's. This is for my own piece of mind more than anything - IF she agreed to getting an IV line in, would this keep her more stable between nebs? What is the first line of medication for IV?
