Question How Do I Avoid Hitting an Artery/Vein When Injecting Insulin?

I really need to know how some of you go about avoiding that old artery "hit" when injecting insulin. My insulin info all warn me not to inject into an artery or vein, but, every once in the while, I still "hit" one, and when the needle comes out, so does the blood.

Your suggestions will be greatly appreciated.

Shalom,

Pastor Paul

You are injecting insulin into subcutaneous fat layer. The chances of you injecting into a vein are almost nil. Arteries run deep so it is highly unlikely you could hit one if you tried. You may be hitting some capillaries in the skin layer with your needle and thats what makes that drop of blood sometimes come out. Capillaries are very small and again, it is highly unlikely that you would inject a full dose of insulin into one. Your needle would go right through it. It does it to me occasionally and sometimes it even leaves a small bruise. Just be sure that you pinch up a bit of fat before you inject if you are a very lean person to be sure you get into the fat layer and not the muscle. The muscle will hurt and the absorption rate of the insulin wont be the same. Also be sure you are using the right size needle. They have a 5/16" short needle that is good for young people and pretty lean people....and they have a 1/2" needle for those of us with a little more padding :P

Cheers

Pam: I hit a capillary every once in awhile. It bleeds a little. I also pinch up some flesh. I have always used a short need and I have a little more padding. Does using a short needle then pose a problem?

I dont think it poses a problem for hitting capillaries...I use the longer needle and it still happens to me. I prefer the longer needle to be sure I get well into my *abundant* fat layer :P

Pam,

A I appreciate your feedback. I do the pinch thing, so it is good to know I may be hitting those small capillaries. That makes sense, and it explains the bruises. I'm rather new to injecting so often (4 times a day) as opposed to once a day before they switched me to Novolog before meals.

I use the bootee for the brunt of my injections. I can't use my thigh because I have a lot of muscle there, and very little fat to hit. I've been told that I can inject in my arms too, but, my questions is, where in the arm?

You've been a big help in easing my concerns, so thanks a whole lot!

Pastor Paul

I use my abdomen most of the time. I find I have the best absorption rate there. Plus, its the easiest to get to. I will sometimes use my thigh I just have to pinch up as much as I can since they are leaner than my tummy. Its hard to reach your own arm..especially using the pens. Usually I get my hubby to give it to me there. If you use your arm the best place is the back of your arm where it tends to be the "fleshiest". Again, be sure you pinch enough so that you don't hit muscle. The first time my hubby did it for me it went right into the muscle...ouch. http://www.diabetesselfmanagement.com/pdfs/pdf_2184.pdf There is a basic diagram of places to inject. Hope this helps!

One thing I have noticed on those rare occasions where draw blood is the insulin acts faster because it is absorbed quicker. So if you do strike blood while injecting watch your sugars and make sure you don't go low quicker then normal.

It is possible... I've had it happen twice in the last 5-6 years. That is why I wrote this post, I wondered if anyone had a secret to missing the "blood tubes". I've gotten some very good suggestions and feedback...
