ABSTRACT This study was undertaken to compare survival and morbidity until discharge in infants born after 22-23 versus 24 weeks' gestational age (GA).
Cohort study of all infants 25 weeks or less, born in 3 tertiary perinatal centers (1999-2003).
Of a total of 336 infants, 133 (40%) died before or immediately after birth without the provision of life support, 203 (60%) received active neonatal treatment. Infants with life support (n = 82 at 22 to 23 weeks, n = 121 at 24 weeks) differed with respect to antenatal steroid prophylaxis (44% vs 62%) and cesarean section rate (51% vs 71%). Survival was 67% compared with 82% (P = .016). The incidence of intraventricular hemorrhage III or greater or periventricular leukomalacia (15/15%), severe retinopathy of prematurity (18/15%), and chronic lung disease (40/47%) was similar in both GA groups.
The provision of life support for extremely preterm infants increases their chance of survival without more neonatal morbidity.

    ABSTRACT: Abstract Objective: We aimed to determine the long-term neurodevelopmental outcome in extremely preterm infants of 22-23 completed week's gestation as compared to infants of 24 weeks with immediate postnatal life support born in two German tertiary perinatal centres between 1999-2003. Methods: Children were assessed for cognitive and neurological outcomes at the age of 7-10 years. The test battery included a neurological examination, the Wechsler Intelligence Scale for children (WISC-IV) and the Frostigs Developmental Test of Visual Perception (DTVP-2). Gross motor function was classified according to the GMFCS and functional activity was assessed with the Lincoln Oseretzky Motor Development Scale (LOS KF 18). Results: Outcome data were available for 79/105 children. 75.9% of the entire study cohort showed no or mild impairment. There was no difference seen between the two gestational age groups. Risk factors for moderate or severe impairment were an intracerebral haemorrhage >II° and/or periventricular leukomalacia or a retinopathy of prematurity >II°. Neither the gestational age nor the birth weight was associated with longterm outcome. Conclusions: Gestational age was not a predictor for longterm impairment of preterm infants born <25 completed weeks gestational age. Other prognostic factors should be taken into account for counselling in the grey zone of viability.

    ABSTRACT: With very preterm deliveries, the decision to institute intensive care, or, alternatively, to start palliative care and let the baby die, is extremely difficult, and involves complex ethical issues. The introduction of intensive care may result in long-term survival of many infants without severe disabilities, but it may also result in the survival of severely disabled infants. Conversely, the decision to withhold resuscitation and/or intensive care at birth, which is an option at the margin of viability, implies allowing babies to die, although some of them would have developed normally if they had received resuscitation and/or intensive care. Withholding intensive care at birth does not mean withholding care but rather providing palliative care to prevent pain and suffering during the time period preceding death. The likelihood of survival without significant disabilities decreases as gestational age at birth decreases. In addition to gestational age, other factors greatly influence the prognosis. Indeed, for a given gestational age, higher birth weight, singleton birth, female sex, exposure to prenatal corticosteroids, and birth in a tertiary center are favorable factors. Considering gestational age, there is a gray zone that corresponds to major prognostic uncertainty and therefore to a major problem in making a “good” decision. In France today, the gray zone corresponds to deliveries at 24 and 25 weeks of postmenstrual age. In general, babies born above the gray zone (26 weeks of postmenstrual age and later) should receive resuscitation and/or full intensive care. Below 24 weeks, palliative care is the only option offered in France at the present time. Decisions within the gray zone will be addressed in the 2nd part of this work.
