Hi, I am an oncology nurse that is need of some advice. There is a new medication for prostate cancer that requires a patient placement of a permacath for Leukaphoresis. This will take place every 2 weeks x 3 treatments. The permacath is placed only for the purpose of the Leukaphoresis and will only be used by the Red Cross Apharesis Team. We recently received conflicting instructions on care and maintenance of the Permacath. How often should this be flushed if it is only used every 2 weeks. What is the procedure? Please help!
