If a patient has a mediport and isn't flushed monthly, when do youÂ draw the line when accessing it? What is the longest period of time without flushing a port,Â would you still access it? 3 months, 7 months, 2 years, or longer? Wouldn't the patient be proned to infection or a blood clot the longer it was not properly maintained? Does anyone know of any data that gives a timeframe? Thanks.
