[Capillary blood coagulation in the healthy premature newborn].
Blood coagulation of healthy premature newborns, since birth, was studied for 45 days by a method of capillary blood sampling in a plastic tube. The most often measured clotting factors allowed to establish control coagulation times for the tests performed in premature sick infants. In this study, the clotting factors were identical in at-term and premature children. Vitamin-K dependent factors showed the most important deficits; however, at birth their levels seemed higher in at-term newborns. They reached control values after one month, with a progressive evolution. The other blood-clotting factors were normal.
