Efficacy of oral water soluble vitamin K in neonates.

Effect of oral water soluble synthetic Vitamin K on prothrombin time was evaluated in 120 full term exclusively breast fed babies. Group A (n = 30) received 1 mg vitamin K (menadione sodium disulphite) intramuscularly at birth, Group B (n = 30) received 0.5 mg intramuscularly, Group C (n = 30) 1 mg orally and Group D (n = 30) did not receive any vitamin K. Prothrombin time (PT) was measured in all between 36-72 hours of age. The PT values in the four Groups A, B, C and D were 17.1 +/- 2.68 seconds, 17.2 +/- 4.42 seconds, 17.0 +/- 2.86 seconds, and 33.1 +/- 12.2 seconds, respectively; the control being 17.0 seconds. The differences between Groups A, B and C were insignificant. Group D babies had a significant prolongation of prothrombin time (p less than 0.001) as compared to the other groups. It is concluded that oral water soluble vitamin K at birth is as good as injectable vitamin K. It is a much simpler form of prophylaxis and avoids intramuscular injection.
