Purpose
The purpose of this study is to determine whether Nasal intermittent positive pressure ventilation (NIPPV) non synchronized is better than continuous positive airway pressure (NCPAP)in preventing extubation failure within 72 h, after extubation of very low birth weight infants at the NEOCOSUR Network.

- Extubation failure [ Time Frame: apnea rate and respiratory failure. ] [ Designated as safety issue: Yes ]
The criteria for failure were met by at least 1 of the following:
pH less than 7.25 and PaCO2 over 65 mmHg; recurrent apnea more than 2 episodes per hour associated with bradycardia; during 4 hour continuous; 2 episodes of apnea that required bagand-mask ventilation in any time during the study; or a PaO2 less than 50 mm Hg with a fraction of inspired oxygen over 0.6.

Active Comparator: CPAP ventilation mode
Once the patient is extubated, CPAP ventilation mode is inmediately administered in order to prevent reintubation
|
Procedure: CPAP ventilation mode
Patients are ventilated through a nasal prong coneected to a ventilator that provides a continuous positive airway pressure
|
|
Experimental: NIPPV ventilation mode
NIPPV: Non Invasive Ventilation mode is administered inmediately after extubation to prevent reintubation
|
Procedure: NIPPV ventilation mode
Patients are ventilated through a nasal prong connected to a ventilator that provides a non synchronized intermittent positive pressure ventilation
|
Detailed Description:
Is a Randomized trial to preterms infants <1500g and less than 34 weeks with RDS requiring machanical ventilation in the extubation period, randomized to receive NIPPV or NCPAP once extubation criteria were met. Parental written informed consent is required previous extubation. The failure rate is defined as the need for re-intubation and mechanical ventilation).
Exclusion criteria are: major congenital anomalies; presence of cardiovascular instability;intubation less than 2 hours; mechanical ventilation more than 14 days, using muscle relaxant, airway anomalies, consent not provided or refused.
Outcome measures:
The primary outcome was to assess the need for re-intubation within the first 72 hours after extubation in the 2 groups.
The criteria for failure were met by at least 1 of the following:
pH < 7.25 and PaCO2 > 65 mmHg; recurrent apnea more than 2 episodes per hour associated with bradycardia; during 4 hour continuous; 2 episodes of apnea that required bagand-mask ventilation in any time during the study; or a PaO2 < 50 mm Hg with a fraction of inspired oxygen > 0.6. The secondary outcomes concerning respiratory support were total duration on ETT ventilation, total duration on NCPAP, total duration on supplemental oxygen, incidence of pneumothorax,BPD and dead. Other outcomes included incidence of patent ductus arteriosus (PDA), necrotizing enterocolitis, intraventricular hemorrhage grades 3 and 4, retinopathy of prematurity stage 3, time to full feeds, and length of hospital stay.
Sample size calculations for the primary outcome: We estimated that there would be a more than 80% chance of detecting 43% difference between the groups (alpha 0.05) when samplesize (n) is 110 patients for each mode of treatment.
