[Prenatal and postnatal determination of gestational age of small newborn infants].

Low birth weight infants are a heterogenous group of babies with medical risks that may vary according to gestational age. The degree of prematurity should be assessed using non-invasive valid methods. The purpose of this study was to assess the validity of four most commonly used methods for the assessment of gestational age in two groups of 60 appropriate for date pre-terms and 29 small for date babies. Our results support the use of prenatal assessment of gestational age by maternal history and early ultrasonography in afd-infants, the use of the examination of the anterior vascular capsule of the lens in afd and sfd infants and physical criteria rather than neurologic criteria when using the Ballard score.

Prevention of symptomatic patent ductus arteriosus with ethamsylate in babies treated with exogenous surfactant.

Some trials in premature infants with respiratory distress syndrome have shown an increased incidence of patent ductus arteriosus after exogenous surfactant therapy. The effect of prophylactic ethamsylate on patent ductus arteriosus after intratracheal administration of a single dose of porcine surfactant preparation (Curosurf, 2.5 ml/kg) was studied in a group of 20 preterm infants with severe respiratory distress syndrome. Gestational age of the patients was 29.2 +/- 2.5 weeks (mean +/- SD), and birth weight was 1158 +/- 319 gm. Ethamsylate (12.5 mg/kg) was given prophylactically within the first 4 hours of life followed by 6-hourly doses for 4 days. Hemodynamically significant patent ductus arteriosus occurred more frequently in the untreated group (8 of 10) than in the ethamsylate group (2 of 10) (p < 0.02). No acute adverse effects were attributed to the therapy. This preliminary experience suggests that ethamsylate, an inhibitor of prostaglandin biosynthesis, could be useful in reducing the incidence of patent ductus arteriosus in very low birth weight infants treated with exogenous surfactant.

[Double phototherapy with Wallaby optic fibers versus conventional phototherapy. Case reports].

The authors have valued the efficacy of the double phototherapy with fiberoptic Wallaby vs conventional phototherapy in 2 groups of term infants, without any complication at birth, utilized respectively as study group and control group. While conventional phototherapy produced a bilirubin reduction of 0.60 +/- 0.26% per hour (with a total reduction of 28.1 +/- 11.1%), the double phototherapy was statistically more effective (p < 0.05) then conventional phototherapy causing a bilirubin reduction of 0.73 +/- 0.28% (with a total reduction of 33.3 +/- 9.5%). At 24 hour after the interruption of the treatment 9 newborns of the study group (36%) and 7 of the control group (28%) presented a rebound effect (increase of the bilirubinemia more than 17 mumol/l), but without a statistical difference (p > 0.05). Our study shows that double phototherapy with Wallaby fiberoptic and conventional phototherapy represent a valid strategy in the treatment of the non haemolytic neonatal hyperbilirubinemia, because, compared to conventional phototherapy, double phototherapy is more effective and reduces the period of the treatment, showing a simple management of the jaundiced newborn.
