To observe the early neonatal vitamin K (VK) deficiency and risk factors. Serum vitamin K deficiency or antagonist-induced protein (PIVKA Ⅱ) levels were determined by enzyme-linked immunosorbent assay. The risk factors were analyzed and statistically analyzed. Results The observed rate of VK deficiency within 5 days of neonatal inpatients with non-medication during the first trimester of pregnancy was 44.86%, the full-term children were higher than those of premature infants, both groups
