title: [Determination of intestinal blood losses in full-term infants].
abstract: Eleven normal full-term newborn babies with no intercurrence in perinatal period were studied to determine the volume of intestinal blood losses during breast feeding in the first week of life. Cr51 labelling method was used. The conclusions drawn are: 1. Normal newborn babies have blood intestinal losses ranging from zero to 0.104 ml/24 hours. 2. Intestinal blood losses determined in this study are negligible and allow the conclusion that human breast milk is not responsible for intestinal blood losses that occur during the first week of life.
