INSULIN CONVERSION
A total daily dose of insulin (TDD) =
N X Wt in
Kg
(N= 0.5-1.0 for obese, resistant & most type 2 DM)
Administer:
½ as Basal (Long acting) & ½ in 3 divided doses a day before each meal
Target pre-meal BG < 140 & random BG < 180 in non-ICU pts
For patients who aren’t transitioning from IV insulin or who
aren’t on an insulin regimen at home, many experts offer these rules of thumb
for estimating the total daily dose:
* 0.3 units/kg/day for patients who are lean, on
hemodialysis, frail and elderly, insulin-sensitive, or at risk for
hypoglycemia;
* 0.4 units/kg/day for a patient at normal weight;
* 0.5 units/kg/day for overweight patients; and
* 0.6 units/kg/day or more for patients who are obese, on high-dose steroids, or insulin-resistant.
