i have an MD who orders only single lumen PICC's, under duress. example: pt vented, three peripheral lines, 1 femoral triple lumen, art line. meds vanco, cefepime, flagyl, norepinephrine, propofol, cardizem, fentanyl. wanted to get rid of the femoral triple lumen. ordered a single lumen PICC, (Bard). called her back and asked for a double lumen. she denied stating the dual lumen is known for more infections and thrombi. approached with meds and compatabilities, vesicants, irritants, poor vessels, long term need. still only wanted a single lumen. How and what can i give her to approach the .35mm difference in a PICC size, advantages, and need for access? I have not heard of the dual lumen 5 Fr causing more infections. BTW--our record after 5 years of PICC insertion is 0 infections. Please help.
