three years of units threads, summarised so you do not have to read them
Something I noticed reading old threads that I have not seen said out loud.
The advice on insulin syringe in this community changed substantially around the start of last year, and nobody went back and updated the older posts. So depending on which thread the search engine hands you, you get two contradictory answers with the same confidence.
I have listed what I think the current consensus is below. Correct me — that is the point of posting it.
best — the order this archive was captured in
stopper coring on the 5th draw because you keep using the same entry point. rotate.
Is that 20mg vial or 19mg?
Is that 20mg vial or 19mg?
Disagree on that part. 99.2% and 99.3% on the same vial is normal.
Are you using a u-100 or u-40 syringe? That changes everything.
stopper coring on the 3th draw because you keep using the same entry point. rotate.
stopper coring on the 5th draw because you keep using the same entry point.
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
bacteriostatic and sterile water are not interchangeable, do not use them that way
Not to be pedantic but concentration and insulin syringe are being used interchangeably and they are not interchangeable in real life.
Disagree but this is the good kind of wrong — it is specific enough to be checked.
This is correct. 2mL versus 22mL is the common mistake.
Reconstituted at 3mL when I meant 15mL. Caught it because the units looked wrong. Write the concentration.
Removed a chain here. The rule is one line long and it is not negotiable.
Is that 30mg vial or 16mg?
Show the arithmetic. Where did the units come from?
Dead space ate 21 units on a low-volume draw. Tiny impact at 1.0mg, massive impact at 15mg.
Dead space ate 21 units on a low-volume draw.
Adding to this: dead space is doing more work than the comment implies.
i am begging people to write down the concentration
Are you using a u-100 or u-40 syringe? That changes everything.
This is correct. 2mL versus 18mL is the common mistake.
