Diaphragm Electrical Activity of Preterm Infants on nCPAP With Binasal Prongs Versus RAM Cannula


Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Preterm Infants | Diaphragm Electrical Activity | RAM Cannula | respiratory distress syndrome of newborn | Continuous Positive Airway Pressure
  • Age: Between 1 - 1 Years
  • Gender: Male or Female

Inclusion Criteria:

  • Clinically stable preterm infants (defined as: cardiovascular stability with normal blood pressure and heart rate for GA and no recent increase in apneic episodes or spells and confirmed by the attending neonatologist) with birth weights less than 1500 gr and/or gestational age bellow 32 weeks, admitted to the NICU at Sunnybrook Health Sciences Centre on nasal continuous positive airway pressure of 5 to 8 cmH20 support, for at least 48 h and requiring less than 35% of oxygen.

Exclusion Criteria:

  • Infants with congenital anomalies of the gastrointestinal tract, phrenic nerve damage, diaphragmatic paralysis, esophageal perforation; infants with congenital or acquired neurological deficit (including significant intraventricular hemorrhage greater than Grade II), neonatal seizure; infants with significant congenital heart disease (including symptomatic PDA); infant with congenital anomalies of the diaphragm; infant with congenital anomalies of the respiratory tracts (e.g. Congenital Cystic Adenomatoid Malformation (CCAM)) infants requiring ongoing treatment for sepsis, necrotizing enterocolitis (NEC), antibiotics for lung infections, narcotic analgesics, or gastric motility agents will be excluded. Infants on nasal CPAP and requiring more than 35% oxygen will be excluded from the study. Infants with significant gastric residuals and vomiting, infants with facial anomalies, infants with pneumothorax or pneumomediastinum, and infants in the immediate postoperative period will be excluded. Infants with nasal excoriations will be excluded from the study as they may be electively placed on the RAM cannula to prevent further nasal trauma.

Recruitment Status: Open
