Still having some pushback regarding the need for a "virgin" line for parenteral nutrition. Is a "virgin line" a requirement? If a line is "dedicated" for nutrition, what and how much flush is required prior to initiating nutrition? If blood components were previously infused via the now-dedicated line, is vigorous flushing all that is required prior to dedicating the line for nutrition? Any references I can provide for the MD with questions/concerns? Thank you all for any information and support you can provide. Your input is greatly appreciated.
