[Neonatal mortality and morbidity in gestational age shorter than 30 weeks for babies treated primarily in a central hospital. Follow-up studies of an unselected, consecutive patient group].

Aim: The aim of the study was to investigate the mortality and morbidity of very premature babies treated at a Danish county hospital in the mid-1990s.

Materials And Method: The 62 survivors of 70 consecutive babies born in 1993-1997 were given a neuropaediatric follow-up examination at a corrected mean age of 49 (22-69) months. The mean gestational age was 27 (24-29) weeks and the mean birth weight was 1012 (550-1374) g.

Results: Eight babies (11%) died within 28 days of birth. Four (6%) had an intracerebral haemorrhage, grade 3-4; four (6%) had retinopathy of prematurity; and three (4%) had bronchopulmonary dysplasia at 36 weeks of gestation. Four of the survivors developed cerebral palsy. Two of these babies and a neurologically normal baby had visual impairments. None developed epilepsy.

Discussion: Thus, our babies had a low mortality and only a few complications at long-term follow-up. Early nasal continuous positive airway pressure and early supplementation with a surfactant seem to be essential for these positive results in our most premature babies.
