Aim: To determine growth, neurological and cognitive development at 5 years of preterm infants with birthweights <501 g born in three German tertiary perinatal centres between 1998 and 2001. Methods: Structured neurological examination, the Gross Motor Function Classification Scale and the Kaufman-Assessment-Battery Test for Children. Results: Of 107 infants, 48 received immediate life support (gestational age 25.2 weeks [21–30.7]; birth weight 435 g [290–500]) median [range]), 27 (56%) survived until follow-up [95% CI 39–69%], 19 (70%) could be tested. In few infants had catch-up growth taken place. Neurological test results were normal in five infants (26%) and mildly abnormal/severely abnormal in 11 (58%)/3 (16%) infants. Visual impairment was present in eight (42%), and hearing disability in three (16%). The mean mental processing composite (IQ) was 82 [50–104] (median [range]). Conclusion: Of all resuscitated infants with a birthweight <501 g, 56% survived to school age. Of these, composite outcome score showed normal development or mild disability in one-half, and moderate or severe disability in the other half of them. Investigators should include such infants in studies and their reports should give specific information about them. [ABSTRACT FROM AUTHOR]

Aim: To report survival and morbidity until discharge in preterm infants <501 g with life support started immediately after birth.Methods/study Design: Cohort study of all preterm infants with birthweights < 501 g born in three tertiary perinatal centres between 1 January 1998 and 31 December 2001 (gestational age (GA) 25.2 [21.0-30.7] wk; birthweight 435 [290-500] g; median [range]).Results: A total of 107 infants with birthweights <501 g were born. Twenty-nine were stillborn. A prenatal decision to initiate life support immediately after birth was reached in 9/37 (24%) infants <24.0 wk GA and in 39/42 (93%) infants > or =24.0 wk GA. Survival was 3/37 (8%) and 26/41 (63%) in infants <24 wk GA and > or =24.0 wk GA, respectively. Twenty-nine of the 48 infants with immediate life support (60%) survived (95% CI: 46-75%). Forty-two of these 48 (88%) infants were small for gestational age. No infant without immediate life support survived (0/30). Twenty-three (79%) survivors developed chronic lung disease (CLD) and eight (28%) received photocoagulation for retinopathy of prematurity (ROP).Conclusion: In this population of extremely low birthweight infants, survival was higher than in previous studies when life support was provided immediately after birth. Short-term morbidity was similar to other studies. The presented data on survival support our concept to offer immediate life support after birth in preterm infants with birthweights <501 g. The long-term outcome of these infants needs to be assessed urgently. [ABSTRACT FROM AUTHOR]
