vitamin K deficiency

overview

The disease that occurs in newborns within 1 week is called neonatal hemorrhage, and the disease that occurs in infants is called tardive vitamin K-dependent factor deficiency. The main clinical manifestations are skin hemorrhage, hematemesis, hematochezia, and long-term bleeding at the puncture site. They are often combined with intracranial hemorrhage and pulmonary hemorrhage leading to death. Severe intracranial hemorrhage often leaves sequelae. The disease is a common disease in newborns and infants. It is more common in children who are simply breastfed within 3 months without their mothers eating vegetables. The onset is rapid and the condition is serious, making it easy to be misdiagnosed. However, as long as there is sufficient understanding of the disease, the disease can be completely prevented. Once it occurs, as long as timely treatment is provided, the prognosis is good. If it is severe intracranial hemorrhage, the prognosis is poor. Therefore, vitamin K should be used preventively for pregnant women, nursing mothers and children who may cause vitamin K deficiency.

There may be bleeding anemia. 4. Half of the children develop intracranial hemorrhage, and develop irritability, loud screams, frequent vomiting, and repeated convulsions. In severe cases, they develop coma, irregular breathing, and in severe cases, cerebral hernia.

diagnostic basis

Only breast-fed infants within 3 months. 2. The onset is acute, with widespread bleeding tendency throughout the body,
