[Clinico-epidemiologic considerations on 533 jaundiced newborn infants treated with phototherapy].

The authors have conducted a clinical and epidemiological study on 533 newborn infants with marked jaundice treated with phototherapy. They have considered the incidence of jaundice in relation to sex, etiology, gestational age and weight at birth. The authors have also evaluated the minimum, maximum and mean duration of phototherapy of different groups of newborn infants with hyperbilirubinemia. Finally an estimation of initial, peak and final serum bilirubin concentration has been conducted together with an estimation of hourly increases and decreases of this concentration during phototherapy.
