Hi, I am looking for some information regarding tunnel lines and the dacron cuff. Has anyone had a patient with an allergy to the dacron cuff? We have a patient who presents like he may have a dacron allergy-swelling and fluid collection around the cuff-aspirated fluid and not infectious. Incidentally treated with steriods for colitis and swelling improved, however once off steriods came back and was larger/tender. His tunneled line prior to this one he developed granulation tissue and the cuff became exposed. He unfortunately needs daily PN so he needs a line. Currently has a PICC line but not a great solution as this is a somewhat temporary line. He is a pediatric patient and will likely need a line for years to come. Anyone have any thoughts on the best type of line to place or any experience with dacron allergy would be helpful...Thanks!
