[Artificial respiration of premature infants].

Better understanding of respiratory physiology and progress in ventilator technology have contributed to improved mortality and morbidity of premature neonates. Yet, pulmonary complications remain high and there is no consensus about the optimal regimen of mechanical ventilation. We report our satisfactory 10-year experience with conventional mechanical ventilation based on a relatively low incidence of pulmonary barotrauma. The introduction of surfactant has facilitated the ventilatory management of premature neonates since the usually rapid improvement of the acute lung disease after surfactant administration allows for earlier weaning from mechanical ventilation. However, our own results and the results from most surfactant studies show no significant reduction in the incidence of intraventricular haemorrhage. Thus, though mechanical ventilation and surfactant administration are milestones in neonatal therapeutic management, the problems encountered in very low birth weight neonates both with respect to mortality and morbidity have not been generally solved and underline the role of optimal perinatal management.
