The purpose of this study is to evaluate four different nasal continuous pressure systems, which are usually applied on our neonatal intensive care unit, with regard of their effect on bradycardia and desaturations in preterm infants.

Condition Intervention
Continuous Positive Airway Pressure
Apnea of Prematurity
Device: Stephanie (TM), Infant Flow (TM), Infant Flow advance (TM), Bubble CPAP

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single Blind
Primary Purpose: Treatment
Official Title: Randomized Trial Investigating Four Nasal CPAP Systems in the Management of Apnea of Prematurity

Further study details as provided by University Hospital Tuebingen:

Primary Outcome Measures:
  • Cumulative percentage of bradycardia (heart rate <80 beats/min) and desaturation (SaO2 <80%) per hour [ Time Frame: one year ]

Secondary Outcome Measures:
  • - Event rates for central apneas, desaturations and bradycardias calculated as the number of respective events per hour of artefact free recording time - relative cumulative event time - baseline heart rate, respiratory rate and oxygen saturation [ Time Frame: one year ]

Enrollment: 16
Study Start Date: March 2004
Study Completion Date: January 2006
Detailed Description:


Apnea of prematurity (AOP) is a common problem in preterm infants. Nasal respiratory support using either Continuous Positive Airway Pressure (CPAP) or Intermittent Mandatory Ventilation (IMV) are, among others, widely used treatments. Which of the different systems is the most efficient, however, is unclear.


Efficiency of different CPAP systems on reducing the cumulative percentage of bradycardia and desaturation in preterm infants.


In a prospective, randomized, cross-over trial 32 preterm infants Infants will randomly allocated to receive nasal CPAP delivered by one of the following sys-tems: (1) a conventional IMV-System (Stephanie, Stephan GmbH, Germany with PIP 15 cmH2O, RR 10/min) delivering CPAP via short binasal prongs (Hudson RCI, USA); (2) the Infant-Flow-System (EME Ltd, Great Britain) with CPAP delivery via short binasal prongs; (3) the Infant-Flow-AdvanceTM-System used in the pressure assist mode with PIP 10 cmH2O, RR 10/min; and (4) a nasal underwater bubble CPAP with application via binasal prongs (Hudson RCI, USA).

All systems will be adjusted to achieve an approximate PEEP of 6 cm H2O. Each study lasts 24 hours, during which chest wall and abdominal movements, SaO2, tcPCO2, ECG, esopha-gus pressure and CPAP-/IMV-pressure will be recorded continuously. Infants will be studied in room air in a 15° head tilt prone position while being treated with caffeine (3mg/kg/d).

PRIMARY OUTCOME MEASURE Cumulative percentage of bradycardia (heart rate <80/min) and desaturation (SaO2 <80%) per hour.
