I'm pleased to welcome you to this podcast for a crucial topic in the care of preterm babies: the use of surfactant therapy guided by tests of their lung function. Practice is evolving in this area, and we're here to discuss the latest evidence. Three guests are joining me today, Greta Sibrecht and Franek Borys, authors of the October 2023 Cochrane review, and, later, Anna Lavizzari, lead investigator for one of the ongoing studies.
