Supplementary Material for: QuickSF: A New Technique in Surfactant Administration

<i>Background:</i> Recent studies indicate an increasing use of less invasive surfactant administration. Different techniques have been shown with distinct risks and benefits. The aim of this study was to develop a new method that simplifies this procedure. <i>Objectives:</i> An applicator was developed and tested on a manikin to make tracheal surfactant application easier and faster. <i>Methods:</i> A device for oral administration of a catheter into the trachea was developed. After refining, it was tested by 9 neonatologists on a manikin. The primary aim was device feasibility, which was defined as successful intubation within 30 s. <i>Results:</i> The first device showed success in 30 of 33 measurements (90.9%). After refinement, the final device showed successful intubation in all 27 trials (100%). <i>Conclusion:</i> The new technique was feasible in this manikin test and should be confirmed in a clinical study.
