Title: Intrapulmonary Percussive Ventilation and Nasal Continuous Positive Airway Pressure Ventilation in Transient Respiratory Distress of the Newborn: A Randomized Controlled Trial
Brief Summary: During caesarean section, transient respiratory distress which occurs frequently (3%) with possible complications are at present managed by non invasive nasal continuous positive airway pressure ventilation (nCPAP) associated with oxygen therapy. Intrapulmonary Percussive Ventilation (IPV) is a non-invasive ventilatory mode used in some intensive care units to treat some respiratory distress syndrome of the newborn with a good tolerance, but without evaluation in prospective studies


Options:
A: Inclusion Criteria:

* gestational age between 25+0 and 32+6 weeks;
* birth weight more than 600 g;
* supported with any type of endotracheal ventilation;
* Has not had first attempt at extubation(extubation readiness requires fulfilling of all the following criteria: a. Having received at least one loading dose of 20 mg/kg and 5 mg/kg daily maintenance dose of caffeine citrate; b. pH\>7.20 PaCO2\<=60 mmHg (these may be evaluated by arterialized capillary blood gas analysis or appropriately calibrated transcutaneous monitors. Venous blood gas values cannot be used); c. Paw \<=7-8 cmH2O; d. FiO2\<=0.30; e. sufficient spontaneous breathing effort, as per clinical evaluation).;
* Obtained parental consent. Informed consent will be obtained antenatally or upon neonatal intensive care unit admission.;

Exclusion Criteria:

* major congenital anomalies or chromosomal abnormalities;
* Presence of neuromuscular disease;
* Upper respiratory tract abnormalities; ;
* need for surgery known before the first extubation;
* Grade IV-intraventricular haemorrhage (IVH) occurring before the first extubation
* congenital lung diseases or malformations or pulmonary hypoplasia
B: Inclusion Criteria:

D: Inclusion Criteria:

* Gestational age \<32+0 weeks
* Birth weight \<1500 g
* Received mechanical ventilation via an endotracheal tube for ≥120 h
* Caffeine treatment according to unit guidelines
* paCO2 \<65 mmHg with pH \>7.2
* FiO2 25-40% to maintain SpO2 at 90-94%.
* Time-cycled, pressure-controlled ventilation: PIP ≤22 cm H2O, PEEP ≤6 cm H2O; Volume guarantee ventilation: Working Ppeak ≤22 cm H2O, PEEP ≤6 cm H2O; High frequency oscillation ventilation: Pmean ≤12 cm H2O, Amplitude ≤30 cm H2O
* Decision of the attending clinician to extubate

Exclusion Criteria:

* Major congenital malformation requiring surgery
* Duct-dependent congenital heart disease
* Neuromuscular disease
* Participation in another randomized controlled trial
* Death before reaching the eligibility criteria
* Hydrocortisone treatment at the time of enrolment
* Chronological age \>28 days
