Surgery and insulin doses

Can anyone advise please, I am going for my pre-admission tomorrow and I'd like to have some opinions so that I can discuss with them.

I am having an op with a general anaesthetic, lasting about an hour. I have to go in for 4pm and they have said don't eat from 12 noon. I take my BI at breakfast and bedtime. Should I reduce my BI, and if so at which injection? Should I test before noon and if low, eat something to bring me up to normal BG and if high, correct with QA? Should I time breakfast for about 8am so that there is 4 hours until 12 and if necessary eat something. My actual op will probably be nearer 5pm. Thanks for any advice.

I would keep your breakfast BI the same, no changes, by the time 12:00 - 13:00 comes your breakfast insulin will have expired and you will be running on nothing but your BI dose, this should hold you steady throughout the operation.......you should be on target, if your over target a tad then I would leave it without correction, if your low then you obviously would treat it as you would with any low reading....

If you are unsure whether your BI dose is accurate enough you could drop your breakfast dose by 2 - 3 units just so your running a wee tad higher over the course of the operation..

your surgeon would be aware of your condition and have preparations in place eg hypo resolve to hand I would assume..

My experience from 5 ops is that the anethiest (?) had me on a glucose drip with insulin and looked after the lot !

Keep an eye on your sugars pre and post op just to make sure.

As richard.arkle has said from previous experience, I myself have had an op in which the anethiest has put me on a glucose drip
