I understand how the BD Diffusics catheter is different than a standard IV cannula. Its design reduces the destabilizing effects that can cause extravastion during a power injection. Somehow our nurses have come to believe that it also reduces other complications such as phlebitis and infiltration. They have been told they need to give Vancomycin through the 22 gauge Diffusics. Even if this was true I find it curious that only Vancomycin had been identified as irritating and now I am getting calls to replace a perfectly good IV because they need to give Vancomycin and it is not a Diffusics!
I also understand that the Difffusis enables higher flow rates with a smaller catheter and gravity flow rates are improved by about 20 percent. Some nurses have told me they have been told that the 22 is really a 20 gauge and the 20 gauge is really an 18 gauge. I also would like clarification on this because while I understanfd the higher flow rates it does not make sense to me because a 22 is still a 22!
The nurses also told me that they have been told all kinds of things that reduce complications such as there is increased bubbling at the catheter tip, better hemodilution and even something about how the irritating medications do not come into contact with the vein walls. I am finding this hard to believe. I have visited the BD website and can find nothing that indicates this device should be used to administer irritating IV medications
