  • *Multiple selections allowed.

  • †Stabilisation of an infant was defined as SaO2>90% and HR>100/min.

  • ‡Other indications included pneumothorax, abdominal distension, choanal atresia, endotracheal tube obstruction.

  • §Intubation required to immediately secure the airway.

  • ¶Data available for 88 out of 89 intubation encounters.

  • **Data available for 85 out of 89 intubation encounters.

  • CPAP, continuous positive airway pressure; DL, direct laryngoscopy; FiO2, fraction of inspired oxygen; HR, heart rate; NICU, neonatal intensive care unit; PMA, postmenstrual age; SaO2, oxygen saturation; VL, video laryngoscopy.
