COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Newborn infants who require intubation and ventilation, from birth until time of discharge from the level 3 neonatal unit, as deemed necessary by the attending doctor will be randomised to intubation with (intervention group) an introducer (stylet). A single intubation attempt should usually take no longer than 60 seconds but multiple attempts are often reuired. For the purposes of this study only the first attempt will be randomised. The duration of ventilation will be determined by the doctor responsible for the infant and is not an outcome in this study.
Intervention code [1] 1366 0
Treatment: Devices
Comparator / control treatment
Newborn infants who require intubation and ventilation, from birth until time of discharge from the level 3 neonatal unit, as deemed necessary by the attending doctor will be randomised to intubation without (control group) an introducer (stylet).
Control group

Immediately after the randomisation takes place and the intubation is attempted.
Secondary outcome [1] 4336 0
Duration of intubation attempt
Timepoint [1] 4336 0
Secondary outcome [2] 4337 0
Physiological instability during intubation attempt (oxygen saturation and heart rate)
Timepoint [2] 4337 0
Secondary outcome [3] 4338 0
Rates of complications associated with each method - airway trauma, incorrect (Endotracheal Tube) ETT placement or dislodgement.
Timepoint [3] 4338 0
All complications will be recorded within 24 hours of intubation.

Brief summary
Orotracheal intubation of newborn infants requiring respiratory support is difficult and often requires multiple attempts. Oral intubation may be performed using an endotracheal tube on its own or with an introducer (stylet) to help guide the insertion. We hypothesise that intubation is more frequently successful and performed quicker using an endotracheal tube with an introducer (stylet) than without and may be the preferred method of intubating newborn infants.
