Management of respiratory distress syndrome in moderate/late preterm neonates: A Delphi consensus.

Introduction: Respiratory distress syndrome (RDS) is the most frequent cause of respiratory distress in preterm neonates. In the management of RDS, surfactant plays a pivotal role, but there are no evidence-based recommendations for moderate/late preterm neonates (32-36 weeks).

Methods: A scientific committee developed a questionnaire with 53 questions addressing diagnosis, treatment, potential complications and future trends in RDS specifically focused on moderate and late preterm neonates. This was followed by the performance of a Delphi survey of expert neonatologists.

Results: Consensus was reached on 98 of the 109 items. The recommendations for the diagnosis of RDS included performing a lung ultrasound and including mild respiratory distress, transient tachypnoea of the newborn, congenital pneumonia and primary pulmonary hypertension in the differential diagnosis. Most panellists agreed on the need for studies that determine the benefit/harm balance, clinical profile and methods of surfactant administration in moderate/late preterm neonates. All respondents would use the MIST approach with devices specifically designed for surfactant administration. Regarding sedation measures during MIST, most participants agreed on the use of nonpharmacological interventions and, if these proved ineffective, an opioid. All respondents agreed that moderate/late preterm neonates are at increased risk of neonatal morbidity and mortality, particularly respiratory problems, and considered the need for more specialised monitoring in hospital follow-up visits in neonates with associated risk factors or a history of complications in the neonatal period. Finally, all respondents agreed that there is a lack of studies identifying risk factors and medium-term adverse outcomes in moderate/late preterm neonates.

Conclusion: This expert consensus will help with the diagnosis and management of RDS and guide decision-making about surfactant administration in moderate/late preterm neonates.
