Vitamin K and Thrombotest values in full term infants.
The vitamin K dependent clotting factors were measured by the 'Thrombotest' on the second day of life in 72 healthy full term babies, half of whom had received vitamin K at birth. Forty eight of these were breast fed, and those not given vitamin K had significantly lower Thrombotest values than those who had received vitamin K. By contrast, administration of vitamin K did not affect the Thrombo...

Appleyard, W. J., and Cottom, D. G. (1970). Archives of Disease in Childhood, 45, 705. Effect of asphyxia on thrombotest values in low birthweight infants. Thrombotest was used as a measure of coagulation status in 55 low birthweight infants. The initial levels were similar in both babies who were asphyxiated at birth and in those who had uncomplicated deliveries. On the other hand, 24 hours af...
متن کاملEffects of Vitamins K in Neonates and Young Infants
Vitamin K is required for the hepatic production of blood coagulation factors II, VII, IX and X. The term vitamin K refers to a variety of fat-soluble 2-methyl-1, 4-naphthoquinone derivatives. Vitamin K1 (phylloquinone) occurs in green plants, while vitamin K2 (menaquinone) is synthesized by microbial in the gut. The recommended dose of vitamin K in neonates is 1 mg intramuscularly. For infants...
متن کاملThe prolongation of the thrombotest clotting time in newborns.
As judged from thrombotest dilution curves clotting inhibiting material was present in 67% of human umbilical cord plasma samples of healthy full term infants (n = 40). The correlation coefficient (r-value) between the thrombotest clotting times and the prothrombin levels was -0.46. Using sensitive enzyme immuno assays for fibrin degradation products (FbDP) and fibrinogen degradation products (...
متن کاملPlasma levels of protein C and vitamin K-dependent coagulation factors in patients on long-term oral anticoagulant therapy.
Plasma levels of protein C (PC) and vitamin K-dependent coagulation factors (factors II, VII, IX and X) were measured in 100 specimens from patients on long-term warfarin therapy. Both activities and antigens of these coagulation factors were decreased, depending on the thrombotest values. Factor II activity/antigen ratio and factor X activity/antigen ratio were correlated well with thrombotest...
