Have a question re: angles for injections

  1. I was just curious what is the best way to give a subcutaneous injection. I am a recent graduate to nursing and I was taught to go in at a 45 degree angle in subcutaneous tissue. It makes sense to me b/c of the layers of skin and muscle.
    The reason I ask is because I've watched a few of my co-workers giving insulin and they are going in at a 90 degree angle in to the tissue. Also, a lot of their s/c's end up bleeding afterwards. I have never encountered this. Any help would be greatly appreciated.

    I generally give them at a 45 degree angle, but my instructor said either way works. I haven't had trouble with bleeding afterward, but that just may be the luck of the draw, too.

    Thanks cyberkat, it's nice to know that I don't have to bite my tongue every time I see someone do the injections.

    Hehe. It's ok. I've seen people do it that way. It's just easier for me to approach at 45 degrees. Maybe it's easier for them to go straight in?

    The only time I angle is if they don't have very much fatty tissue. With a insulin or TB syringe, there is really no need to angle except in the aforementioned circumstance.

    You should also check your drug book! Certain meds should be given at a 90 degree angle instead of 45.

    Agree.

    Agree with the posts about the amount of fatty tissue the client has.

    Usually use 45 angle, except for Lovenox-per inservice it is to be given at 90 angle.

    I remember that about Lovenox but I can't remeber why. What's the rationale for that again?

    Insulin is supposed to be given at a 90 degree angle, as are other SC injections (unless specifically contraindicated for the particular drug), but it thin clients you may go at a 45 degree angle.
