Abstract
|
|
|
A prospective study was done on the 70 normal newborns observed in the nursery of the Chungnam National University College of Medicine, to evaluate the renal function with relation of feeding time and amount during the Period of 8 months from Jan. 1987 to to Aug. 1987
The results were as follows:
Ninety-three % of subjects voided initially within 24 hours and 100% of them within 48 hours. The average time of initial voiding was 13.8±9.48 hours.
The value of specific gravity and osmolality of the initial urine were 1.008±4.99 & 279.5±152.6mOsm/kg respectively and proportionally related.
Urine & feeding amount during the 1st 24 hours were 43.5±32.3cc & 112±47.31cc respectively and proportionally related.
Initial feeding time was 8.5±3.39 hours and urine & feeding amount during the 1st 24 hours increased as the initial feeding time early began.
