U100 syringes and U40 insulin help please.

My order of U100 syringes has finally arrived :-D I'm quite sure I understand the conversion (multiply a U40 dose insulin by 2.5 when using the U100s), but I just want to be doubly sure that my syringes are correct before I use them (I do believe I've admitted to paranoia before :mrgreen: ).

They're in 10s but other than that look pretty good to me. I've attached an image. All good, right?

Thanks in advance :smile:

Thanks for the quick replies.

Oh yes, I was planning on drawing up a reference sheet for Toby (10-12mmol gets .5 on the syringe, 12.1-14.5mmol gets 1, etc), I won't be doing any 'guessing' :smile:

I can't find any mention of the 3/10mL, maybe because they're only bagged? But they look like the image on the right on that link.

Thanks again.
 
If your syringes look like the one on the right in the link pic, they have 5 marks between each numbered line. If yes...then each line is equal to one unit per the U100 measurement. You will have to eyeball your half/quarter/etc. doses.

Each line is a unit, so the "10", for example, is 10 units of U100 insulin - or 2 units of U40, correct? Ergo, if I want to give Toby .2 units of U40 insulin using this syringe, I draw to the very first - the 1 unit of U100 - line?

Looking at them now, they're actually .5ml, not .3ml, but that only changes the size of the syringe, I think? nailbite_smile

Sorry about making it complicated and thank you for the help :dizcat
 
Becky.....

I have to giggle a little here....I did this with someone else a few weeks ago. Bear with me on my questions:

Are there 5 lines between the numbered lines?

OR

Are there 10 lines between the numbered lines?

Just want to make sure I know exactly what yours physically look like. :smile:

It's okay, I know I'm not making it easy :lol: I thought I was only checking the units of measurement...

5 lines between the numbered lines. First number 5, last 50. 0.5ml syringe.

Thanks again.

Hold on.... I am checking something to make sure about the conversion. Want to make sure our chart is okay for your 0.5ml's. :smile:

No, .2u of Prozinc U40 would equal .5u in a U100 syringe.
.4u would equal 1.0u.

Yes, exactly. The .3 ml and .5ml are just the total volume of the syringe.
 
Thanks Carl.....I was not sure about Becky having the 1/2cc syringes instead of the 3/10cc ones. :smile:

BECKY.....when you indicate your doses on your spreadsheet, be sure to use the U40 amount. That will make it easier for all of us here to help you.

Yeah, I had it mixed up between the first mark and one unit then :? Anyway, I got it sussed out now, thanks.

Yup, will be doing. Thanks :-D
 
U-100 means 100 units per mL
U-40 means 40 units per mL
so U-40 insulin is only 40% as concentrated.
(Although each unit is supposed to have a certain amount of biological activity.)

If you have half unit markings, you can just count per mark, 0.2, 0.4, 0.6, etc.
If you have only unit markings, you can count 0.4, 0.8, 1.2, etc.

Hi Becky,

The .3ml BD syringes can come with half unit markings (marked on the box as '+ demi'). I use those and would be happy to send you some if you'd like to try them...?

Thank you for the lovely offer, but we just used a U100 for the first time and quite easily eyeballed a .25 :-D I'll remember for next time that I want the .3s :razz:

Looks like those U100 syringes arrived at just the right time, Becky!
That .1 of a unit was a good call last night.

Eliz

Indeed. He's managed .25 at those kind of numbers before, but .25 has also been doing more to him recently :-D Coulda done with a drop this morning but we were very limited when it came to monitoring him, and then he threw me a 7.4 this afternoon... I want more data before we go that low. We can watch him pretty close tomorrow though :mrgreen:
 
This may be helpful:

Here are some glucose reference ranges used for decision making using glucometers. Human glucometer numbers are given first. Numbers in parentheses are for non-US meters (mmol/L). Numbers in curly braces are estimates for an AlphaTrak.

< 40 mg/dL (2.2 mmol/L) {< 70 mg/dL for an AlphaTrak}
- Treat as if HYPO if on insulin
- At nadir (lowest point between shots) in a long term diabetic (more than a year), may earn a reduction.

< 50 mg/dL (2.8 mmol/L) {< 80 mg/dL for an AlphaTrak}
- If before nadir, steer with food, ie, give modest amounts of medium carb food to keep from going below 50 (2.8).
- At nadir, often indicates dose reduction is earned.

50 - 130 mg/dL (2.8 - 7.2 mmol/L) {80 - 160 mg/dL for an AlphaTrak}
- On insulin - great control when following a tight regulation protocol.
- Off insulin - normal numbers.
(May even go as low as the upper 30s (1.7 mmol/L){60s for an AlphaTrak}; if not on insulin, this can be safe.

= 150 mg/dL (8.3 mmol/L) {> 180 mg/dL for an AlphaTrak}
- no shot limit for ProZinc, PZI, or other non-depot insulins

> 150 mg/dL (8.3 mmol/L) {> 180 mg/dL for an AlphaTrak}
- At nadir, indicates a dose increase may be needed when following a tight regulation protocol.

200 mg/dL (11.1 mmol/L) {230 mg/dL for an AlphaTrak}
- no shot level for beginners; may slowly reduce to 150 mg/dL (8.3 mmol/L) {180 mg/dL} for long-acting insulins (Lantus, Levemir, and ProZinc) as data collection shows it is safe

180 - 280 mg/dL (10 - 15.6 mmol/L) {may be 210 - 310 mg/dL for an AlphaTrak}- Any time - The renal threshold (depending on data source and cat's renal function) where glucose spills into the urine.
- Test for ketones, glucose is too high.

>= 280 mg/dL (15.6 mmol/L) {may be >=310 mg/dL for an AlphaTrak}, if for most of the cycle between shots
- Uncontrolled diabetes and thus at risk for diabetic ketoacidosis and hepatic lipidosis
- Follow your insulin protocol for dose adjustments
- Test for ketones; if more than a trace level of ketones, go to vet ASAP.
