Late intracranial hemorrhage by vitamin K deficiency: an analysis of 56 cases

Objective To study the etiological factors and preventive measures of intracranial hemorrhage associated with vitamin K deficiency. Methods A retrospective study was carried out as to the clinical features and outcome of intracranial haemorrhages by late vitamin K deficiency in 56 infants who were admitted to our hospital during a 4-year period (June 1998-June 2003). The risk factors for intracranial hemorrhage associated with vitamin K deficiency included exclusively breast-fed infants (45/56), diarrhea (18/56), history of antibiotics (16/56) and liver disease (2/56). All patients were treated by giving vitamin K, lowering encephalic high pressure, repelling convulsion, transfusing fresh blood and phlebotomy. Results 49 cases (49/56) were healed, 2 (2/56) dead, 5 (5/56) abandoned, 34 (34/49) with nervous system sequelaes. Conclusion For infant patients with exclusively breast-fed, diarrhea, history of antibiotic and liver disease, it is of great importance to enhance preventive measures besides routine preventive measures.
