When giving an I.M can you give the 2 injections in the same needle by changing the syringe?

I've been taking Promethazine IM injections for many years, so my answer is the same, No!
I'm sitting here trying to figure out how you are able to leave the needle inside a muscle & change only the barrel part, then re-attach. Granted if it was taped down, going in a vein, as hospitals do, I would understand more.
Sorry for my confusion, but in a nutshell, I would stick to the answer of no.
Better to be safe than sorry, too much chance of infections, etc.

No, No and NO! You cannot leave the needle in and change the syringe. No! Two syringes and two needles, separate injections, separate sites! It is the only way! The way you describe would hurt the patient plus it breaks aseptic technique!

NOooooooooooooooooooooooooooooooooo. You can't give both in the same place without hurting the patient, and you can't stick the same needle more then once its not sterile after the first time. Use two needles, two syringes and two sites.
