LISA Rigid Catheter vs LISA Soft Catheter in a Very Preterm Manikin

Less invasive surfactant administration (LISA) can be provided using rigid or soft catheters, but possible differences in terms of easiness of use and success of the procedure are unknown. A difficult procedure may have some drawbacks such as the prolonged duration of the laryngoscopy needed to insert the device, which is likely to aggravate the invasiveness of the procedure and result in stressful consequences such as bradycardia, hypoxia, and hemodynamic changes. Objectives: i) time of device positioning, ii) success of the procedure of positioning the device, iii) participant's satisfaction.
