[The therapeutic use of pulmonary surfactant in neonatal hyaline membrane disease].

Preliminary report of our experience with the therapeutic use of pulmonary surfactant in newborn infants of less than 30 weeks gestation with hyaline membrane disease. The use of pulmonary surfactant was held under the "rescue" modality, with up to 36 hours of postnatal life. The blood gas changes are described and the assisted ventilation progress, as well as the general response on the clinical condition of each case.

[Hearing and language sequelae in survivors of a neonatal intensive care unit].

Introduction: The purpose of this study is to record the hearing and language sequelae in a sample of children from the Intensive Care Unit between the ages of two and three.

Materials And Methods: Forty-one children were studied after being submitted to neuropsychological, hearing and language tests. Both normal and abnormal parameters for each test allowed the categorization of the children.

[The anemic gap in depressed newborn infants].

Thirty cesarean section-delivered newborn were studied. Fifteen of them scored from 0 to 3 and, 8 and greater on the Apgar scale when measured at one and five minutes, respectively. The other 15 scored 8 or more at one minute and 9 at five minutes.

[The Apgar score as a predictor of neurologic sequellae].

65 newborns with Apgar score less than 7 were studied. Initially 2 groups were formed. Group 1 with severe asphyxia Apgar 0-3 and group 2 with moderate asphyxia Apgar 4-7.

[Determination of C-reactive protein in low-risk newborn infants].

We present the results of the determination of C-reactive protein (CRP) in neonates with low risk of developing infection and without obstetric trauma. In determining the values of CRP we used the technique of latex agglutination. We included 56 neonates determining the changes in the values obtained in samples of cord blood and 24 hours.

[Clinical characterization of a sample of newborns at risk of presenting with an altered neurologic evaluation].

Being the Prachtl's Neurological Sieve a systematic condense analysis of neurologic screening which allows to establish a normal or suspicious neurologic condition at a sensibility of 0.85, and specificity of 0.77 with a predictive value of 0.

[Neurologic follow-up of polycythemic newborn infants].

Seventy five newborn infants with neonatal polycythemia diagnosis (venous hematocrit levels greater than 65% were studied). They were born in the Instituto Nacional de Perinatologia and follow through their first year of life searching for neurologic findings. The more frequent signs related to polycythemia in this group were: presence of plethora, respiratory distress, cyanosis and tremors; the associated findings were hypoglycemia, hyperbilirubinemia, necrotizing enterocolitis and meconium aspiratum.
