ABSTRACT

Introduction: the results of the progress of ventilated newborns weighing less than 1 500 according to modes of ventilation in Cuba are still unknown. Objective: to describe the results of the short-term progress of preterm infants weighing less than 1 500 g, according to the modes of invasive mechanical ventilation. Methods: a cross-sectional study was conducted in 87 preterm newborns weighing 1 500 g, who had been ventilated in a provincial reference center in Cuba in the period of 2008 through 2014. On the basis of the medical histories, the study variables were mode of ventilation, background, reason for and stay in ventilation, complications and mortality. By means of absolute and relative frequencies, the general characteristics of the ventilated patients were described as well as their neonatal results in general and according to the modes of ventilation. Results: in the group of studied patients, 71 % received synchronized mechanical ventilation, 10 controlled ventilation and 19 % elective high-frequency oscillatory ventilation. When making a comparison of the conventional mechanical ventilation with the elective high-frequency oscillatory ventilation, the former showed higher survival index (80.3 vs. 56.3 %), lower frequency of pneumothorax (4.2 vs. 31.1 %) and less requirement of repeated doses of surfactant (36.6 vs. 68.8 %), all of which was significant (p< 0.05). The patients requiring both modes of ventilation -controlled and intermittent synchronized mandatory- showed higher survival rate (90.9 %). Conclusions: description of short term results of progress of preterm ventilated newborns weighing less than 1 500 g, according to the modes of ventilation, allows setting up a framework of reference for the evaluation of the mechanical ventilation, although the differences found do not solely depend on this factor.
