#injection-technique 2024-12-16

90 degrees works fine if you have the tissue for it. 45 if you do not

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call

bleeding a little means you nicked a small vessel. it is not a technique failure

warm it first

do not reuse pins. it is not about sterility so much as the tip being blunt after one pass

i mark the rotation in a notes app because the marks fade and i lost track twice

follow up abdomen two inches out from the navel, avoiding anything that has been injected in the last month

do you change the pin between drawing up and injecting

pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising

small bubble is fine

fresh pin

sharps bin

do not aspirate for a subcutaneous injection, there is nothing to aspirate for

nobody here should be telling you where to inject. we can tell you what we do, i could be wrong

warming the vial in your hand for a minute is the cheapest comfort improvement there is

cold from the fridge genuinely stings more. i let it sit out for ten minutes, happy to be corrected

the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small

i changed nothing except letting the swab dry and the stinging stopped completely

mark it down

a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it

drawing up with the same pin you inject with is fine, it just dulls the tip slightly
