title: [Treatment of neonatal respiratory distress syndrome with Alveofact--results of a prospective observational study].
abstract: OBJECTIVE
  After registration of the bovine Surfactant Alveofact (Fa. Thomae) for treatment of neonatal respiratory distress syndrome (RDS) an observational study was performed in 47 german neonatal departments to register indication, effectivity, mode of administration and unexpected side effects.
  
  
  METHODS
  680 ventilated preterm infants (gestational weeks 29.5 +/- 2.9; birth weight 1359 +/- 507 g) were enrolled in an uncontrolled clinical study with study-protocol, prospectively defined outcomes and covariates, manual of operation, central control system, biometrical control.
  
  
  RESULTS
  Surfactant was applicated at a postnatal age of 2 hours 56 minutes (median). Only 2.9% of newborn infants got the first surfactant doses < 6 min postnatally, 19.4% between 6 ... 60 min and 77.7% > 60 min postnatally. Following 1338 instillations in 76% an improved lung function, in 21% no change and in 3% a worsening was observed. During the study the total dose of surfactant increased. Safety considerations determined by the rate of pulmonary and extrapulmonary complications were similar to data of the literature: pneumothorax 12%, pulmonary interstitial emphysema 11.6%, secondary pneumonia 20.4%, broncho-pulmonary dysplasia 27%, pulmonary hemorrhage 2.1%, peri/intraventricular hemorrhage (degree III/IV) 27.9%, ductus arteriosus persistens 24.4%, sepsis/meningitis 12.4%. During the study the mortality reduces from 31% (first period) to 18% (third period) the mean was 20%. In 44 infants (6.5%) a disturbed ventilation (airway obstruction, overdystension of pulmonary areas, atelectasis) after surfactant administration was observed.
  
  
  CONCLUSIONS
  In RDS the surfactant Alveofact is preferably used therapeutically (rescue mode), it is effective but not free of risk. Its administration needs for a clear indication. New unknown side effects of Alveofact were not observed.
