Hello
I have just completed my first B12 intramuscular self-injection into the outer thigh. It seemed to go relatively smoothly, but I do have some observations and questions. Firstly, my B12 comes in an ampoule and I found extracting it from the B12 with a thicker green needle then switching to a thinner orange needle rather cumbersome. As such, would it be a better idea to stick with the orange needle for extraction and injection?
Secondly, regarding aspiration- Just after inserting the needle, I pulled back on the syringe plunger slightly to check for blood entering the syringe and did not find any (although the colour of the B12 liquid makes it difficult to see and contrast it with any blood). However, after removing the needle, there was some bleeding (not a great amount, just some small bubbles) for which I applied a plaster. Does this mean that I aspirated incorrectly and injected into a blood vessel? Should I change my technique in future?
Thirdly, regarding the attachment of the needle to the syringe- I use the terumo syringes with the separate attachable needles. The needles come out of the packet with a plastic cover that shields the needle. I found myself unable to attach the needle without first removing the plastic cover as my attempt to remove the cover with the needle attached to the syringe caused me to pull the needle off the syringe end. I was careful not to touch the needle itself whilst attaching it (I only handled the green/orange needle 'mount' on one end) . Was I ok in attaching the needle in this way, or should I practise attaching the needle with the plastic cover in place then removing it when the needle is attached?
Hopefully, I have done everything safely, but I must admit to feeling a bit nervous as this was my first time injecting myself with anything. I washed my hands before doing anything and wiped the ampoule and injection site on my thigh with alcohol swabs before injecting, so hopefully I was at least sanitary.
Thanks
