⇒ keep POCT glucose 80-180 mg/dL, first urgent RI dose = 0.1 ū/kg
$$ TDD = a × BW;\ \bold{use\ 0.5\ generally}
$$
$a = \begin{cases}0.7&\text{in DM patients on corticosteroid}\\ 0.6&\text{in T2DM patients with POCT >180 mg/dL } \\ 0.4&\text{in T1DM, CKD patients} \end{cases}$
⇒ $Basal = 0.5×TDD$ as NPH or insulin glargine if encountered NPH-induced hypoglycemia
⇒ $Bolus=\frac{1}{n}\times0.5\times{TDD}$ as regular insulin given postprandially n meals (generally 3 regular meals)
Mr. A (a 80-kg diabetic patient) with initial POCT 240 mg/dL should get :
