The proposal was to use a 1/2 inch of Nitropaste over or slightly distal to the insertion site of a basilic vein to dilate it so that the venipuncture and entire threading procedure would be easier in a vessel. Not for small diameter veins but to increase a 5-6mm vein so that vein wall damages are minimized with threading. Possibly decreasing initial trauma and provide preventative strategy for later DVT complications. Certainly screening patients with low B/P issues would negate this practice as NP may further drive systemic vasodilation in an unpleasant direction.
Is any one using Nitropaste either PRN or routinely under an approved Medical Protocol (via your Medical Director) for the above reasoning. I have heard of this practice performed during PICC insertions and would like some "pro and con" comments - if it is still being used....even occassionally.
Thanks very much!
