Sugar speed (mg/kg. Min) = liquid velocity (ml/h) x sugar concentration (only specific values are taken, and% is removed, for example, sugar concentration is 12%, and 12 is taken instead of 0. 12) ÷ (6x weight).

Namely: sugar speed (mg/kg min) = liquid speed (ml/h) x sugar concentration ÷ (6x body weight).

Example: 10% glucose 60ml+ amino acid 40ml intravenous drip, the sugar concentration in this group of liquid is equal to 10%×60 ÷(60+40)= 6%.

Example: pump speed 10ml/h, weight 3kg.

Sugar speed: 10× 6× 3 = 3.33 mg/kg * min.
