[IP] Hi Karen--kids and pumping
I bet you are excited, but also nervous about the pump start up. I know
that I was.
My Claire starting pumping 13 months ago, she was age 6 but about to
turn 7. She was average size (can't remember weight, but now is 59 pounds)
and I think used about 24 units with needles. She was very sensitive to
Regular and Humalog, NPH didn't work on her at all. Claire is a good eater
and eats a lot, about 210 carbs a day, both pre-pump and post-pump.
Her basal rate was started at .3. She was really somewhere between .3
and .4 according to my calculations, but the nurse said, quite correctly, to
start lower and then move it up if needed.
The carb ratio used to start her was 1:15. I have NEVER heard of 1:10
used in kids. Claire now uses a 1:20 ratio if she is eating before exercise
or lots of fun playing, eg at lunch at school when outdoor recess immediately
follows. I have noticed that in the mornings she needs more insulin, but we
still use 1:15, running a higher basal rate in the morning hours.
I am in Canada, so the high bg correction factor sounds a lot nicer in
our measuring system--.1 unit of insulin drops her 1 mmol. Translated to the
USA system, .1 unit drops her 18 points, and thus .5 unit drops her 90
points. This is what the nurse suggested to us at start-up, based on her
experience with kids. It works very well, except when bgs are very, very
high, as you have probably heard about before. I would advise you to be
extremely careful in giving high bg boluses!!! One half unit without food
will likely drop your daughter a lot, unless she isn't sensitive, but with
such a low daily dose it sounds like she must be quite insulin sensitive.
I'm not telling you to disagree with your doctor, but if it was me, I
would just use the ratios and correction factors that I felt were the best
for my child. Does your team have experience with young kids? Is this the
starting rate they use with all kids? Or is there something particular to
Are you a member of the Parents of pumpers list? If you post your
question there, you will likely get lots of other responses. Maybe you
already have, I am on digest mode, so it takes me awhile to get the mail.
Good luck! You can write me with any other questions if you want, but
we are moving house next week so computer may be out of service for a bit.
