deltoid IM flu vaccine technique

I'm doing a flu clinic coming up and am reviewing the literature about flu vaccine recommendations. There have been a couple great threads about technique, but my specific question is the site. I understand you're to inject 2 finger breadths below the acromion process. I've always done these no problem but now I'm getting nervous and second guessing myself.

This gives a great visual of the injection site. However, this seems a little higher, i.e., right over the greater trochanter which makes me nervous to hit bone while injecting. Do you guys find that you inject right over the greater trochanter or just below, but still on the deltoid muscle?

Thanks
You're thinking too much. Relax, you won't feel a thing.

I always inject pretty high-up when giving IMs, you shouldnt hit the bone as long as you bunch up the muscle in your fingers.

haha so true! I'm getting nervous for nothing. I'll be at some fancy law firm, not a traditional hospital or clinic setting, so I'm a little nervous. People in suits make me nervous (scrubs or white coats, not so much).

I have a feeling that my flu shot was administered SQ instead of IM...I did not get the classic muscle soreness and it didn't hurt at all during administration. Maybe I just got lucky? Any thought?

I measure with my two fingers and poke right there. It's pretty high because two finger breadths is a small distance.

No, lucky as in that if it was administered correctly, it just didn't hurt.

This is a very confusing thread. First of all, the greater trochanter is attached to the femur. The injection site diagram for the deltoid appears very high; I'd be worried about hitting bursa. How about looking for the meatiest part of the upper third of the upper arm? Size, age, gravity, muscle mass vary so widely from one person to the next; I don't trust textbook diagrams.

Nurse678, if it was administered very quickly, it has a lesser chance of being sore the next day.

I have heard that if you get the patient to let their arm hang loosely by the side of the body, you will have injected in a relaxed muscle - which is supposed to be another way to prevent pain. I think the best way to get used to where to inject is to look at actual anatomy and remember what the deltoid muscle looks like.
