INTRODUCTION: The European guideline for treatment of respiratory distress syndrome recommends less invasive surfactant administration (LISA) as the preferred method of surfactant administration in spontaneously breathing preterm infants. However, there is limited evidence on practical aspects such as sedation and catheter types, leading to considerable variability between centers.
METHODS: An anonymous online survey (<ext-link ext-link-type="uri" xlink:href="http://www.soscisurvey.de" xmlns:xlink="http://www.w3.org/1999/xlink">www.soscisurvey.de</ext-link>) was sent to 164 tertiary neonatal intensive care units (NICUs) in Germany including 43 questions on practical aspects of LISA.
RESULTS: Of 122 (74%) participating NICUs, 117 (96%) reported experience with LISA with 82% of those reporting LISA as their preferred method of surfactant administration. Indications for surfactant administration differed widely between NICUs. Most (89%) used FiO2-thresholds only or in combination with other criteria, such as Silverman score/signs of dyspnea (41%) or lung ultrasound findings (3%). Prophylactic surfactant was administered by 42%. Differences in use of LISA in extremely immature infants were reported (e.g., 36% did not perform LISA in infants below 24-26 weeks). Preferred drugs for sedation were (Es-)Ketamine, followed by Propofol and Midazolam. Minimum time interval between subsequent LISA procedures was 4 (2-6) h. Catheters specifically designed for LISA were used by most NICUs (69%).
CONCLUSION: This survey shows that LISA is common practice in German NICUs, but with considerable variability in practical aspects. These data may serve as a guidance for NICUs that have not yet implemented LISA and might be helpful design clinical trials with the aim to standardize and/or optimize LISA.
