Abstract |
A comparative study of peripheral blood pictures in full term and premature babies from birth to 6 months of age, was done at ped. dept, of Ewha Womans University Hospital. In this study, 30 full term babies and 20 premature babies who were delivered at this hospital during 2 months, March and April in 1968 were subjected for evaluation of peripheral blood picture. The observations and tests were done for the first 6 months period since their birth, also compared the value of blood counts between breast feeding and artificial feeding babies, especialy concering the time of appearance of physiologic anemia. Resert of study: (1)The difference in peripheral blood pictures between full term and premature babies as follows both erythrocytes count and hemoglobin levels were somewhat lower in premature babies compared with those of full term babies.
(A)In full term babies, physiologic anemia began to appear at 2 months of age, and reached lowest levels (Hb. 10. 6 mg%) RBC. 347 million/mm3 Het, 34%) at 3 months after birth. The physiologic anemia of full term babies began to return to normal level at 4 months of age, and stablized at the normal range at 5 or 6 months of age.
(B)In premature infants, physiologic anemia began to appear earlier than in full term infants and reached the lowest levels (Hb. 9. 5 gm%, RBC 285 million/mm3, Het. 30%) at 2 months of age. It began to recover at 4 months after birth, but rate of recovery was slower than full term babies. The anemia did not recover until 6 months of age. (2)The feeding methods such as artificial or breast feeding did not affect on the development of
physiologic anemia and it’s recovery. |
