A Case of Vitamin K Deficiency Bleeding in a Newborn: Catastrophic Yet Preventable.

A four-week-old full-term male infant presented to the emergency department with blood in the diaper, increasing lethargy, and vomiting and was found to have multiple intracranial hemorrhages on CT. He was delivered at home and did not receive vitamin K. Coagulation studies were abnormal, and des-gamma carboxyprothrombin (DCP) was 481, diagnostic of vitamin K deficiency. He received vitamin K and required multiple antiepileptic medications for seizure control. Vitamin K deficiency bleeding (VKDB) is a preventable disease that can have devastating consequences and could present as early, classical, or late-onset. The typical presentation manifests with cutaneous, gastrointestinal, or intracranial hemorrhage most commonly in fully breastfed infants. Vitamin K prophylaxis has proven to be effective. With increasing out-of-hospital delivery and online misinformation, there is a declining administration of intramuscular vitamin K at birth. It is the responsibility of healthcare providers to properly inform patients and their families of the importance of vitamin K prophylaxis at or before the time of delivery.
