Comparison Of Respiratory Support After Delivery on Infants Born Before 28 Weeks Gestational Age (CORSAD)
A Randomised Controlled Trial of Delivery Room Intubation Rates Comparing a New System and T-piece Resuscitation System for Initial Stabilisation of Infants Born <28 Weeks
Trial purpose: For infants born <28 weeks of age, can initial respiratory resuscitation with new system (low imposed work of breathing and prongs) reduce the frequency of delivery room intubations compared to standard treatment with T-piece resuscitator system (high imposed work of breathing and face mask)?
Trial summary: This is a randomised controlled trial of delivery room intubation rates comparing a new system and T-piece resuscitation system for initial stabilisation of infants born <28 weeks.

Status
Descrição detalhada
The study is a two arm randomised comparison of two systems (T-piece device and the new system) for respiratory support after delivery of an infant born less than 28 weeks gestational age (GA). This multicentre trial will start at Karolinska University Hospital and other sites can join throughout the study period. The trial is academic with the coordinating investigator as sponsor. No company funding will be considered.
The new device has been designed for neonatal resuscitation and CE-marked for this intended use. The device is operated/handled in a similar way to existing devices and can provide support according to resuscitation guidelines.
During spontaneous breathing the continuous positive airway pressure (CPAP) provided with the new system is more pressure stable and has low imposed work of breathing. The benefits of decreased imposed work of breathing during resuscitation have not previously been investigated. The new system has the option of using prongs as the patient interface. Prongs have shown promising results in trials and have theoretical benefits. We hypothesis that the combined use of prongs and low imposed work of breathing could reduce the number of infants that need mechanical ventilation.
Screening for eligibility and consent will be performed on mothers with threatening delivery of an extremely premature infant (<28 weeks gestational age). There is no lower gestational age limit but patients should not be included if there is a decision to intubate prior to delivery or treatment limitations.
After a patient has been enrolled the randomisation will be on hold until delivery is imminent. Randomisation will be stratified on centre, gestational age and antenatal steroid treatment. The interventions cannot be blinded.
The management of respiratory support is according to international guidelines and a detailed description is provided in the clinical management appendix. The intervention is respiratory support for the first 10-30 minutes of life and will begin after birth when the infant is transferred to the resuscitation team. The intervention ends 1) when an infant is intubated (primary outcome), 2) after a minimum of 10 minutes support, with the randomized system, the patient is stable and breathing adequately, 3) at 30 minutes when the respiratory support can continue as decided by the clinicians (cross-over not allowed).
Apart from the system used for respiratory support all patients will receive standard care. No assessments or investigations of the trial subjects are planned. Data will be reported by the resuscitation team and collected from records.
The primary outcome is delivery room intubation or death. The secondary outcomes include time to intubation, use of surfactant, use of positive pressure ventilation, respiratory support at 72 hours and temperature on intensive care admission. Safety variables include pneumothorax, intraventricular haemorrhage and problems with ventilation and equipment.
All analysis will be on intention to treat and p<0.05 considered statistically significant. The primary outcome variable (delivery room intubation or death) will represent a 2x2 cross table and analysed with Pearson chi-square test. The secondary outcomes include Kaplan Meier analysis of time to intubation and comparisons of means for continuous variables. There are no predetermined subgroups. Subgroup analysis will be used to describe the population and to generate hypotheses.
