Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A randomised controlled trial of a Respiratory Function Monitor during positive pressure ventilation during resuscitation of infants. A flowsensor will be placed between the mask and the Neopuff T-piece-device. This flowsensor measures the airflow and calculates the tidal volume. Each infant requiring positive pressure ventilation at birth will be recorded with the flowsensor in place, the duration of this recording will last during the initial stabilisation in the delivery room.
The duration of the trial is 12 months; we anticipate completing recruitment in October 2009.

Treatment: Devices
Comparator / control treatment
Positive pressure ventilation (control) (in line with the Australian Resuscitation Council guidelines) during resuscitation of infants. Each infant requiring positive pressure ventilation at birth will be recorded with the flowsensor in place. In th ecomperator group the respiratory function monitor is masked, so that the operator can not see the display or hear any alarms of the repsiratory function monitor. The duration of this recording will last during the initial stabilisation in the delivery room.

Summary
Brief summary
A randomised controlled trial of a Respiratory Function Monitor during positive pressure ventilation (intervention) compared to positive pressure ventilation (control) (in line with the Australian Resuscitation Council guidelines) during resuscitation of infants. The duration of the trial is 12 months; we anticipate completing recruitment in October 2009.

Does the use of a respiratory Function Monitor during positive pressure ventilation reduce face mask leak and improve the target tidal volume in the first ten minutes of life?

During the stressful event of neonatal resuscitation neonatologists do not consider the tidal volume (VT) they deliver, or if there is a leak between the face and the mask.
We hypothesis that a respiratory function monitor will reduce the face mask leak and support the clinician to deliver the target tidal volume during positive pressure ventilation.


Ventilation using a face mask is the main technique used to support infants who breathe inadequately immediately after birth. However, a major problem is the often large and variable gas leak between the mask and face. Face mask leak occurs frequently, even for experienced operators and seriously affects the delivered tidal volume. The tidal volume changes as the leak changes, even though the same inflating pressure is used. In practice this means that for the same inflating pressure the tidal volume may be low, appropriate or excessive depending on the leak.
Furthermore immediately after birth it is not possible to deliver an appropriate tidal volume using ventilation with a set pressure because the compliance of the lung varies from infant to infant and during the course of lung aeration. It is therefore necessary to measure and adjust the tidal volumes delivered during positive pressure ventilation in the minutes after birth, especially in very preterm infants.
We hypothesis that a respiratory function monitor will reduce the face mask leak and support the clinician to deliver the target tidal volume during positive pressure ventilation.
