- Scientific TitleA randomized controlled trial of respiratory function monitoring during stabilization of preterm infants at birth
- ACRONYMMONitoR
- hypothesisTo test the hypothesis that observing the data and waveforms displayed on an respiratory function monitor during the provision of positive pressure ventilation to preterm infants at birth will increase the proportion of tidal volumes within a predefined “safe range” of 4 – 8 mls/kg.
- Healt Condition(s) or Problem(s) studiedPrematurity, Resuscitation
- Inclusion criteriaInfants born will be included in this study if they are between 24 and 27 completed weeks gestation receiving PPV for resuscitation at birth and do not have a known abnormality which might interfere with breathing.
- Exclusion criteriaInfants will be excluded from the final analysis if they are found to have a congenital abnormality or condition that might have an adverse effect on breathing or ventilation, including: congenital diaphragmatic hernia, tracheo-oesophageal fistula or cyanotic heart disease.

- Target number of participants320
- InterventionsAt birth positive pressure ventilation will be given with or without the guidance if a respiratory function monitor. The display of the monitor will be visible or covered.
- Primary outcomeThe proportion of tidal volumes delivered during manual PPV to an infant within the target range of safe tidal ventilation. The target range of adequate tidal volume is defined as 4-8 mL/kg.
- Secondary outcome- Rates of endotracheal intubation in the first 24 hours after birth
- The need for circulatory support over first 24 hours (inotropes and fluid boluses)
- Incidence of air leak (pneumothorax, pulmonary interstitial emphysema,or pneumomediastinum) in the first 72 hours, reported by a radiologist masked to the intervention.
- Incidence of abnormal cranial ultrasound findings (i) all intraventricular haemorrhage, (ii) severe – ie. Papile grade III and IV intraventricular haemorrhage, (iii) periventricular leukomalacia
- Duration of endotracheal (ET) ventilation (hours).
- Duration of nasal CPAP (hours).
- Duration of supplemental oxygen therapy (hours)
- Total duration of assisted ventilation (ET, CPAP) in hours
- Incidence of bronchopulmonary dysplasia (BPD) at 36 weeks corrected gestational age defined as the need for supplementary oxygen and/or any form respiratory support. The severity of BPD will be assessed as proposed by Jobe et al.34 and oxygen reduction test will be performed in case of moderate BPD as described by Walsh et al35.

- Brief summaryExtremely preterm infants often fail to establish efficient gas exchange independently in the delivery room (DR) and many receive mask ventilation or tracheal intubation and mechanical ventilation. However, immediately after birth the immature lung is highly vulnerable to injury.
Achieving effective manual ventilation can be difficult because most clinicians are not aware when mask leak or airway obstruction occur. With variable leaks, variable tidal volumes are delivered that may be either inadequate or excessive causing lung injury. Traditionally, adequacy of ventilation during positive pressure ventilation (PPV) in the DR is assessed by adequate chest rise and an increase in heart rate. Recently, it has been demonstrated that the use of a respiratory function monitor (RFM) can guide PPV in the DR, but data from large trial are lacking. The aim of this multicenter RCT is to test the hypothesis that observing the data and waveforms displayed on an RFM during the provision of PPV to preterm infants at birth will increase the proportion of tidal volumes within a predefined “safe range” of 4 – 8 mls/kg.
320 Infants between 24-27 weeks of gestation will be be randomised to either have the RFM visible or covered. Other than allocation of the visible or masked RFM, all other resuscitative measures (e.g. intubation, external cardiac massage, administration of oxygen and other drugs) will be at the discretion of the staff involved, following local protocols.
Primary outcome is the proportion of tidal volumes delivered during manual PPV to an infant within the target range of safe tidal ventilation. The target range of adequate tidal volume is defined as 4-8 mL/kg. Participating centers:
