Help from extended bolus users please.

[L101418]

Could you please give some insight as to what may have happened with this extended bolus attempt? My brian is mushy from shopping (hate it).
Supper tonight was a hamburger and fries at our favorite local, family owned, Greek restaurant. I (was) pretty confident in the carb count for this meal.

6:21p...128bg...80carbs...
.....>>60% up front (5.40u) -> 40% over 2 hrs (3.55u)
9:00p...249bg
930p...3.3u...30carbs (ate the 30carbs about 15 min later)
10:30p...82bg...treated with 10carb (lots iob-felt dropping)
10:45p...94bg
11:30p...135...1.475 iob

Need more upfront I suppose but I can't imagine that big ol' hamburger was done digesting at 9:30. I guess I didn't expect the 2 hr extended to have a dramatic impact like it seems to have had at 9:30 (wish we had a bg check there). Maybe it's as simple as an overbolus.

Thanks so much!

Perhaps a bit more upfront with the rest extended for a longer time? Or, if the upfront amount was not pre- bolused, pre- bolusing it a bit?

Did the 3.3 units given at 9:30 include any correction? If it did, that might account for the love BGs 1-2 hors later, but from the earlier bolus amount, perhaps it didn't.

So she ate at 6:30 and ate again at 9:30 with an extended bolus already going?

The 3.3 units, how much of that was correction, and how much was for the food? (If it wasn't all for the food.) (edit: oops, didn't see Virgo had already asked this! )

Everyone is different of course, but we've never done an extended bolus for that long for a hamburger and fries. Have you done it for that long in the past with success?

Or was this more carbs (starchy bun / fries type) than she normally has?

[hawkeyegirl]

For a hamburger and fries, we'd extend over five hours. But eating 30 more carbs in the middle of the extended bolus would be a mess for us.

No correction at 9:00 or 9:30

We've done 70/30 over 1 hr but still went a little low at 1.5 hrs. Honestly, I just made it 2 hr extend this time to see what would happen.

Not really, she is a carb hound. She ususally has carb loaded meal ~ 3-5 times a week.

Yes

Why is that? I can't seem to work it out. Because the results of the extend and snack bolus overlap? The snack was chips so I thought that would fast enough acting to avoid problems.

The next couple checks:
2:00a...173...corrected
wakeup...133...with a stuffy nose.

Thanks for the replies and thoughts.

It just adds another variable. I assume the slow-digesting food would slow the digestion of the chips too, and I'd have zero idea how to account for that. My gut feeling is that I'd only do a partial straight bolus for the chips, and maybe wait a while (an hour) and dose for the rest, but I'd be flying by the seat of my pants.

Frankly, your results were pretty good. You could try 75% up front next time and see what happens. (We typically do 70 or 75% up front and 50% over 5 hours, but every kid is different.) I'd also dose conservatively for something like the chips eaten while the previous food is digesting. But all-in-all, you did well with a tough meal.
