AbstractPatients with burn injuries exhibit multiple risk factors for the development of vitamin K deficiency, including malabsorption, limited enteral intake, antibiotic therapy, and multiple surgical procedures. A prospective evaluation of 48 children was conducted to evaluate serum vitamin K values during the first 4 postburn weeks. Serum levels were analyzed in relation to clinical course. Days of antibiotic (p < 0.02) and albumin therapy (p < 0.003), percentage body surface area excised (p < 0.006), and the administration of blood products (p < 0.05) were significantly correlated with serum vitamin K levels, and days of diarrhea approached statistical significance (p < 0.06). No relationship was found between serum values and prothrombin time, activated partial thromboplastin time, or serum albumin. Ninety-one percent of the children demonstrated serum values below expected norms. These data suggest a relationship between coagulopathy and an intact functioning gastrointestinal tract. However, the relative importance of dietary versus endogenous vitamin K produced by intestinal bacteria remains to be elucidated.
