NASAL HIGH FREQUENCY OSCILLATION AND NASAL CONTINUOUS POSITIVE AIRWAY PRESSURE FOR RESPIRATORY INSUFFIENCY IN NEWBORN INFANTS 1946

OBJECTIVE: to evaluate the effect of nasal high frequency oscillation(nHFO) during nasal continuous positive airway pressure (nCPAP) in newborn infants with moderate respiratory insufficiency we performed a non controlled observational study.

PATIENTS AND METHODS: 10 patients (gestational age 25-37 weeks, birth weight 570-3100 gram, age 4 hrs - 21 days) were treated with nHFO. We used an Infant Star ventilator, initial setting mean airway pressure 4-8 cm H2O and amplitude ΔP 35-45 mm H2O. A tube (inner diameter 2,5-3,0 mm) was placed nasally at a depth of 3 cm. Indications for nHFO were clinical signs of respiratory distress, increasing oxygen need and/or CO2 retention during prior nCPAP.
