To Stop Bleeding in Newborns
Vitamin K, phytomenadione, phytonadione
The body uses vitamin K to clot blood and stop bleeding. But babies are born without much vitamin K, so if for some reason they start bleeding it can quickly get out of control. If a newborn starts to bleed from any part of his body (mouth, cord, anus), you can give vitamin K to prevent excessive bleeding. You can also give vitamin K to very small or early babies (under 2 kg) to prevent bleeding because they are more likely to bleed.
Vitamin K does not stop bleeding in older children or adults.
Inject 1 mg (one 1 mg ampule, or ½ of a 2 mg ampule) of vitamin K into the outer part of the thigh within 2 hours after birth.
