Title: Need some help w/ needles
Post by unsolved1 on Feb 1^st, 2005, 4:50pm

Ok ... got these 6mg (0.5ml) vials. I need to get at least 3 mg of Trex. My needles are :

BD Syringe 27G 1/2" 1cc

I think that 1 cc is = to 1 g. Not sure though.

I'm doing some research on this for you, Unsolved and will hopefully get an answer soon.

In the meantime, though, your pharmacist should be able to help you figure it out.

She said 1 cc is = 1 ml

Sound right ??

yeah, that was my gut reaction too - that 1 cc=1 ml. But, after that is where my little pea brain just shuts right down.

I should know this though. Canada went metric, apparently, about 20 years ago. ::)

still waiting for an answer from my gurus for you, but I'm pretty sure you're right about the cubic centimetres/ml thing. Now we just have to remember if there are 1000 mgs in a ml or other way round.

ok - DUH - I shook my head and realized that if 6mgs = 0.5 ml, then 3 mgs will equal 0.25 ml. So, on your syringe, does that make it 25 cc's?

CC (Cubic Centimertre) 3

ML (Millilitre) 3

Fluid Ounces 0.101442

1 ml = 1 cc

I also use the 6mg/0.5ml vile's I use B-D 3ml 25G5/8 Precision Glide Needle. Thy are marked at 1/2, 1,, 1 1/2, 2, and 3ml.
Hope this helps.

Ummmm... I would just peel the label off the vial and use half of it,
or put all of it in the syringe and use half of that.

Hey Michael - ask a nurse (even a retired one might remember a little).

Each of the vials you received are the equivalent of 1 autoinject - 6 mg of Trex. If you need half of that, you want half of the vial.

1 cc = 1 ml

To be sure, when drawing up, draw in the entire amount and check the lines on your syringe, then shoot half of it back into the vial.

You should find that your particular syringe shows you at .25 cc of fluid.

.25 cc on your syringe should equal 3mg of Trex.

The metric system was defined such that a cubic centimeter of WATER . (under certain specific conditions of temperature and pressure) has a mass of 1 gram.

The common sense approach, usually the best one, the one that I don't always think to use. If you use half, just be sure to switch out the needle for next time, makes for less pain, and probably less chance of infection.

For those who care: under standard temperature and pressure (STP) T=25degC, P=1 atm. yes, I am a geek.

Unsolved

3mg = .25cc = 25 units

6mg = .5cc = 50 units

You will find the vial has more than 6mg in it. I usually get 1 syringe with 30 units and one with 35 units. Sometimes I get as much as 40 units in the second syringe.

I use the ReliOn .5cc, 30 guage, 5/16" short needle. Works fantastic!

Just draw the whole thing up, inject half, then cap the syringe for the next use.
