INTRODUCTION
The use of prenatal corticosteroids, the management with CPAP from the beginning of resuscitation and the administration of surfactant together with less aggressive ventilator therapies, offer better results from the respiratory point of view in the extremely premature infants.
The aim of our study is to analyze respiratory management in very premature infants, born before 32 weeks gestational age (GA) during the last eight years.
MATERIAL AND METHODS
We performed a retrospective, cohorts study, including premature infants born before 32 weeks GA admitted to the NICU of a tertiary hospital between 2010 and 2017. The analyzed variables were invasive mechanical ventilation (IMV), non-invasive mechanical ventilation (NIV), high-flow nasal cannula therapy (HFNC), administration of surfactant and need for respiratory support at 36 weeks of corrected gestation.
A descriptive and Kruskall-Wallis analysis was performed.
RESULTS
We analyzed 205 preterm infants less than 32 weeks GA admitted into NICU.
Demographic data are shown in Table 1. 
44.5% of the patients were managed only with NIV.
We observed a trend to decrease the days of IMV with a significant increase of NIV and HFNC in the group of preterm infants from 26-27 weeks GA (p 0.034) (Figure 1).  In 24-25 GA group, an increase in the days of non-invasive respiratory support (NIV+HFNC) was seen (p 0.031) (Figure 2).

CONCLUSIONS: The improvement of NIV devices, have allowed an increase in respiratory support in very low preterm infants, as well as in our subgroup of 26-27 weeks GA a reduction of the days of mechanical ventilation.
