@tim A “sliding scale” is just a method of calculating* an appropriate insulin infusion rate (delivered by a syringe driver rather that by a proper insulin pump) based on one’s blood sugar. I’m sure there is some kind of “standard” but whenever I have been subject to one it has literally been scribbled on a bit of paper by some junior medic and handed to the nearest nurse who then does her own thing. The result is that your blood sugar is well beyond any kind of control for the first 12 hours (as we all know, we are all different) until they start to work out how YOU respond. By then the need for the sliding scale has passed and you go back to your usual delivery method trying to regain control.
All good fun really (not)!
* When I say “calculating”, I mean “guessing”.
