A pharmacist

Hello All, I've been tasked with writing protocols for catheter flushing at our hospital. I don't know tons about catheters, but I'm familiar with the debate and most of the supporting evidence. My preceptor wishes to go with the Heparin 10U/ml for the most part despite the leaning toward NS out in the literature. I have a huge hole in my research and that is what's contained in the INS Standards of Practice. Most guidelines are published with free access, but this one is not and quite frankly it's a bit perturbing they're asking $70 for their recommendations. That aside, I have a couple of questions if I may: Those familiar with these guidelines... would they help in justifying the 10U/ml? If so, is there anywhere to obtain an electronic version or SOMETHING that alteast summarizes their recommendations? I don't need to know everything about catheters, just that which pertains to evidence based flushing recommendations. Thanks in advance for any input.
