Best thing to do is to basal test before...
Ie if you know you will be nil by mouth from the night before op.. try doing it. See what happens to your bloods... get prepared before your pre op assessment. This enables you to discuss any concerns pre op.
I have nit had particukarly good experiences with my last two ops. Both were mastectomies. Very long stories, two diff hospitals. 2nd one new of my concerns, adjusted the sliding scale but still went hypo before op abd they had the wrong concentration of glucose in the drip.
However, my recovery was superb with 2nd op. 1st op I got poisoned after 3rd draining off from seroma build up. 1st op the consultant refused antibiotics during op and after.... if he had given them as I asked I would prob be ok. I could have died according to my oncologist...
However, 2nd op brilliant. Consultant listened. He gave antibiotics during op, twice by injection before leaving the day after and also a week of tablets two. Liquid drained off twice and no problems. No poisoning.
Recovery brilluant from 2nd op.
Dont assume anything!!
If they say you will be first down... check what that actually means. I was first down for both my ops but the breast surgeons operate in the afternoons. So I was taken in at 7.30 for 1st op, 9.30 for 2nd op and both ops were around 2pm.
You need to know if you will be put on a sliding scale. Again, dont assume. Ask. Tell them your insulin regime (we are all different-some do 1 basal in morning, some at night and some like me have 3 shots of basal!).... so ask them what they want you to do.
If you take any vitamins, make sure you tell them. I take oil of oregano but this has to be stopped a week before op because it is a blood thinner... so make sure if you take any vitamins that you tell them.
Or if you have a pump... what happens with it? Will they let you keep it for surgery or not (unlikely).
If you have a cgm ask if it has to be removed pre surgery. Mine did incase they need to use an electric saw thing that could arc!!
Dont rely on nurses on the ward to test you as often as you may need. Make sure if you need to test that you got your meter etc with you.
I had my diabetes educator sat with me 2nd op when I had informed ward nurse I was dropping fast.. I was hypo before the ward nurse thought about turning on glucose and I had warned her. It happened in two hospitals. Then the 2nd hosp also had wrong drip as well so I sucked two sugar cubes and got screamed at that the op would have to be cancelled, nurse would have to tell anaethetist etc... it was ok.. op not cancelled. After the awful experience on 1st op I just said to nurse" I dont care if op cancelled I'm not going to op hypo"..... she was wrong but I never got an apology.
I am unlucky in last two years. Hysterctomy 21years ago on mdi was blooming perfect. Absolutely no problems. Taken in night before, discharged before any other ladies as I was so **** well afterwards...
Just my luck in last two ops, I'm sure you will be fine.
Do basal test... so you know you will be safe with no food....
Dont worry from my experiences. I got another two ops coming up before end of year at 2nd hospital and I have to work on the fact that for me it will be 3rd time lucky.
Also, if I have all the bad experiences, it means others will have the good experiences.....
Do ask for antibiotics as you are more prone to infections...
