For children who have had bleeding, vitamin K1 1~2mg should be injected intramuscularly immediately, which can stop the bleeding quickly. In severe bleeding combined with shock, blood or plasma transfusion can be given immediately to increase the level of clotting factors in the blood and to correct hypotension and anemia. The bleeding can also be accelerated with thrombospondin complex at the same time. If bleeding occurs in the gastrointestinal tract, immediate fasting with intravenous nutritional supplements should be used until the bleeding stops. Since neonatal hemorrhage can cause serious adverse consequences, how can this disease be avoided? The prevention of this disease is not difficult. Newborns need to be supplemented with vitamin K1 at birth and for 3 months after birth, so that neonatal hemorrhage can be completely eliminated. The specific method of administration is intramuscular vitamin K1 1mg at birth or oral vitamin K1 2mg once, followed by the same dose orally every 10 days until 3 months of age. In the case of exclusively breastfed infants it is recommended that mothers take oral vitamin K1 (5mg/day) to increase the vitamin K1 level in the milk. It has also been studied that giving pregnant women oral vitamin K1 prior to delivery can increase the level of vitamin K1 in cord blood and may prevent vitamin K1 deficiency in newborns. The key to neonatal bleeding disorders is still prevention, and it is not difficult to prevent. If parents have any questions about this, they can contact me by telephone consultation.
