HHHFNC (Heated Humidified High-Flow Nasal Cannula) Versus NCPAP for Respiratory Distress Syndrome of Prematurity
- Conditions
- Newborn Respiratory Distress Syndrome
- Interventions
- Device: HHHFNCDevice: NCPAP
- Registration Number
- NCT02570217
- Brief Summary
Preterm infants ranging from 29+0 to 36+6 weeks+days are randomly assigned to one of the following treatments as non invasive respiratory support if they develop mild to moderate Respiratory Distress Syndrome within 72 hrs from birth: 1) NCPAP set at 4-6 cmH2O or 2) HHHFNC providing a flow 4-6 l/min.
The aim of the study is to assess efficacy and safety of relative "new" form of respiratory support (HHHFNC) versus a more common one (NCPAP).
- Detailed Description
Preterm infants are eligible to the study if they present mild to moderate Respiratory Distress Syndrome (RDS) defined by the following criteria: need of FiO2 ( Fraction of Inspired Oxygen) ≥0.30 to keep a target SpO2 (Periferal Oxygen Saturation) beetween 88-93% and/or Silverman score ≥5. To confirm the diagnosis a Chest XR is performed as routinarily in the ward before starting the respiratory support.
They are randomly assigned to one of the treatment groups cited in "brief summary" by means of closed envelops. A block randomization is applided with a blok size of 4. The randomization is stratified per groups accoring to gestational age: from 29+0 to 32+6; from 33+0 to 34+6; from 35+0 to 36+6 weeks+days.
Once the treatment is started, for the group NCPAP there is the possibility to switch to the mode "Bi-PAP" if: there are more than 4 episodes of apnoea per hour or more than 2 episodes requiring positive pressure ventilation or if deemed by clinicians for increased work of breathing assesed by the Silverman score.
For all the groups, if the FiO2 requirement is persistently higher than 0.35-0.40 per target SpO2 86-93% and/or dyspnoea defined by Silverman score \> 6 after starting the respiratory support, newborns receive Surfactant by "INSURE" technique, involving endotracheal intubation by direct laryngoscopic vision, endotracheal administration of surfactant (Curosurf, Chiesi Pharmaceutics, Parma, Italy) 200 mg/kg and finally extubation.
After the administration of surfactant, if FiO2 requirement is persistently \>0.4 to keep SpO2 86-93% or severe apnea episodes are present (apnea episodes \> 4/hr or \>2/hr requiring positive pressure ventilation) or at the blood gas (capillary or venous) PaCO2\>70 mmHg and pH\<7.20, newborns are intubated and mechanically ventilated.
For all the newborns enrolled in the study, capillary or venous blood gas is checked every 6-12 hours, a cerebral and cardiac ultrasound screening is performed within 24 hrs. Further controls follow the routine of the ward.
Weaning is started decreasing HHHFNC flow by 1 lpm or nCPAP pressure by 1 cmH2O pressure if infants are presenting FIO2 \< 0.30 to target SpO2 and minimal or no signs of respiratory effort. The respiratory support is discontinued for flow ≤ 2 lpm or pressure ≤ 2 cmH2O.

Group Intervention Description HHHFNC HHHFNC The patients receive respiratory support by mean of Heated Humidified High Flow Nasal cannula NCPAP NCPAP Patients receive respiratory support by Nasal Continuous Positive Airways Pressure(NCPAP)
- Primary Outcome Measures
Name Time Method number of patients needing intubation and mechanical ventilation within 72 hrs from the beginning of the study mode within 72 hrs from the beginning of the study mode The procedure defined as INSURE and described in details in the section "Detailed Study Description" is not considered as a failure for the primary outcome.
- Secondary Outcome Measures
Name Time Method air-leak syndrome through study completion, an average of 1 year Retinopathy of Prematurity through study completion, an average of 1 year overall duration of respiratory assistance up to 2 years from birth respiratory assistance includes both invasive and non invasive respiratory supports
Necrotising Enterocolites (NEC) through study completion, an average of 1 year overall mortality through study completion, an average of 1 year overall duration of oxygen requirement up to 2 years from birth Apart from invasive and non invasive respiratory supports, for this specific outcome are considered also the days of oxygen administration by devices other then ventilators or HHHFNC devices.
Surfactant treatment through study completion, an average of 1 year the overall number of doses of surfactant are considered
Infections through study completion, an average of 1 year Sepsis, pneumonia, cellulites and other infections are considered
Bronchopulmonary Dysplasia up to 2 years from birth Jobe-Bancalari classification criteria are applied.
Patent Doctus Arterious through study completion, an average of 1 year If a pharmaceutical or surgical treatment is required is considered. Small doctuses closing spontaneously during the first days of life are not included.
overall duration of non invasive respiratory assistance up to 2 years from birth If later during the hospitalisation the newborn receive non invasive ventilation, even if for different reasons from the beginning and/or by mean of a different mode or device, this is registered and computed as "overall non invasive ventilation".
full enteral feeding through study completion, an average of 1 year Number of days required to reach the " full enteral feeding" (defined by a fluids intake about 120 ml/kg/day by enteral administration)
overall duration of hospitalisation up to 2 years from birth Intra ventricular Hemorrage through study completion, an average of 1 year
