Risk Factors for Intracranial Hemorrhage Caused by Late Vitamin K Deficiency / 实用儿科临床杂志

ABSTRACT

Objective To explore the risk factors for intracranial hemorrhage caused by late vitamin K deficiency bleeding(VKDB),in order to prevent and reduce the incidence of intracranial hemorrhage caused by late VKDB.Methods A retrospective analysis of the risk factors of late VKDB and intracranial hemorrhage was applied to 2 groups of patients in PICU and department of neurology of Beijing children's Hospital from Jan.2002 to Dec.2007.In group Ⅰ,there were 90 patients suffering from intracranial hemorrhage caused by late VKDB;while in group Ⅱ,there were 23 patients of late VKDB without intracranial hemorrhage.Within 12 hours of hospitalization,the following 9 items were checkedthe cranial CT,blood calcium concentration,liver function,serum sodium,blood glucose,prothrombin time,partial thromboplastin time,fibrinogen concentration,and platelet.Ten possible relevant risk factors of gender,age,birth situation,feeding patterns,recent diarrhea,cytomegalovirus(CMV)infection,hypocalcemia,dysglycemia,hyponatremia,and abnormal liver function were analyzed by the method of non-conditional Logistic regression analysis.Results Statistically significant difference had been found in the 3 factors of hypocalcaemia,recent diarrhea,abnormal liver function(Pa
