terrible adhesive allergy, possible iodine allergy connection?

My daughter has terrible reactions (not just a little redness...I mean blistering, weeping) to the tegaderm and adhesives associated with the tune ups and PICC line. She also broke out all over her chest last year in what I think was an allergic reaction to the cleaning agent they used for appendectomy, possibly betadine? Iodine? Does anyone know if there is a link? Please, does anybody have any helpful advice, new products, ANY input on this? Tune up is coming, and we are nervous. Thank you for your help.
