Luvenox is brandname form of heparin. It is given
subcutanous... you dont' have to give it "deep" as you are going for the fat layer just under the skin but not all the way into the muscle and vasculature. For best results, give her the shot at the same time(s) each day, as prescribed by your doctor. She is on both heparin and coumadin for the same reasons, yet the coumadin takes a while to take effect therefore the heparin is used for immediate results. See MAB32 cardioversion thread as this is being discussed in that thread as well.
My HH6 was put on heparin when on strict bedrest for several weeks during her pregnancy.
AS NDD stated, aspiration is always a good idea, but it looks like you have a fairly short needle on your little kit so you shouldn't be into the vascular layer under the fat. Also, depending on the gauge of the needle, it may be so small a lumen that a red blood cell can't actually be pulled up into the carpule portion so aspirating may be unnecessary and a waste. Here is what I would do and had to do with my wife:
- Squeeze an inch of skin between your thumb and two fingers, pulling the skin and fat away from the underlying muscle. (If you use a 5 millimeter needle to inject, you don't have to pinch up the skin when injecting at a 90° angle; with this shorter needle, you don't have to worry about injecting into muscle.)
- insert the needle
- Hold the pinch so the needle doesn't go into the muscle.
- Push the plunger in to inject in the heparin.
- Release the grip on the skin fold.
- Remove the needle from the skin.
Good luck and my sympathy to your wife for having to have Mr. Heavy hands aka Torguewrench Joe perform medicine on her after your display with the aimpoint mounts.
