how do you know if you hit a vein or nerve?

[CsB]

hmmm I never pull back on the plunger cause I always know it will fill with blood. everytime I used to inject i took it slowly and it didnt feel like i hit any nerves or veins but i never aspirate after im finished injecting pull it out and see a little drop of blood thats about it

that exactly what i do but i do aspirite it helps to not feel no pain at all, form common sence what i expected was that by the second u hit a vein youll see blood coming out from the edge of the hole even when needleis still inside because of the pressure they have,but about pulling the plunger I feel its pointless and may cause infection, im sure blood will be sucked in either or not hited a vein,Im not saying you all are wrong because im not the person with th right for that but what i mean is i feel tehir is somethng im missing about that fact , if anyone know a text or preferably a video where tehy explain about it would be gratefull

I'm not sure what this means, but when I tried to aspirate I find I am unable to do so. I try to tug at the handle but it seems stuck and the only way it can go is forward (syringe not full, only 1.5 cc). I'm afraid to pull back too hard, so I just assume that if I did hit a vein or blood vessel or something like that the handle would be easy to pull back since blood is trying to get out.

Thats exactly correct, when you try to aspirate and are in a muscle there is nothing to pull into the syringe so a great deal of resistance is felt, if you are in a vein or have gone through one nearby then when you pull back blood will appear. You are also right to not pull hard all it takes is a little pull and if its hard to move then you are good to go.

Thanks! Glad to hear I did it correctly!

This is an accepted procedure, the result of countless hours of theory and practice by people with big ass brains....

Here is an excerpt from Becton Dickerson or (BD) the largest manufacturer of syringes worldwide.

From BD Syringe manufacturer:

Safe injection techniques.

Aspiration:

Although aspiration is no longer recommended for SC
injections, it should be practised in IM injections. If a
needle is mistakenly placed in a blood vessel, the drug
may be given intravenously by mistake and could cause
an embolus as a result of the chemical components of
the drug. Following insertion into the muscle, aspiration
should be maintained for several seconds to allow
blood to appear, especially if a narrow bore needle is
used (Torrance 1989a). If blood is aspirated, the syringe
should be discarded and a fresh drug prepared. If no
blood appears, proceed to inject at a rate of approximately
1ml every ten seconds. This may seem slow,
but it allows time for the muscle fibres to expand and
absorb the solution. There should also be a ten second
wait before withdrawal of the needle, to allow the
medication to diffuse into the muscle before the needle
is finally withdrawn. If there is seepage from the
site, slight pressure using a gauze swab can be applied.
A small plaster may be required at the site. Massage
of the site should be discouraged because it may cause
the drug to leak from the needle entry site and irritate
