I have asthma, and I was scared too. I think it because they take so many precautions and tell you over and over again what the complications are so, things start to creep into your head. As far as the asthma goes... they are going to have you take all of your inhalers the day of the surg and bring them in with you. I took Albuterol right before I went back for the surg and I had no problems. It helped me a little to remember all the people who go under gen anesth. and are fine. Also, you can take them as needed after your surg, and if you feel like you need or want a treatment afterwards, just let your nurses know. Good Luck, and you will be fine!
