title: [Speed of intestinal passage and water content of feces in premature and full-term infants following exposure to phototherapy].
abstract: Fifty-one newborn infants were divided into five groups and were studied according to gestational age, hyperbilirubinemia and phototherapy. In each group, the speed of intestinal passage and content of water in feces was evaluated in terms of the variables mentioned. It was shown that neither hyperbilirubinemia nor phototherapy affect the content of water in feces, nor the speed of intestinal passage in pre-term infants. The same results were true for hyperbilirubinemia in full term infants in whom it was not possible to demonstrate the effect of phototherapy. Full term infants showed a greater content of water in feces and a higher speed of intestinal passage as compared with pre-term infants. This was possibly the result of different body weight due to a different gestational age.
