For this indication, competent medicine agencies globally authorize below treatments:
Intravenous
300 - 300 [iU] per kg of body weight
From 300 To 300 [iU] per kg of body weight once every day
Initially 300 units/kg intravenously, adjusted thereafter to maintain the activated clotting time (ACT) in the range 400-500 seconds.
By continuous intravenous infusion in 5% glucose or 0.9% sodium chloride or by intermittent intravenous injection.
The intravenous injection volume of heparin injection should not exceed 15ml.
As the effects of heparin are short-lived, administration by intravenous infusion is preferable to intermittent intravenous injections.
