[Trends in the management of respiratory distress syndrome in very preterm infants transferred to the Clinical Center of the University of Debrecen].

INTRODUCTION

Although in utero transport is recommended in the case of threatening preterm delivery, it is not always possible. Management during postnatal transport may influence neonatal outcomes.

OBJECTIVE

The aim of this study was to investigate the trends in patient characteristics, respiratory management and outcomes in very preterm infants requiring postnatal transfer between 2008 and 2021.

METHOD: We conducted a retrospective study. Data were collected from both written and electronic medical records. Trends were assessed using joinpoint regression analysis and summarized as annual percentage changes (APC).

RESULTS

A total of 177 infants were included. The number of transfers per year showed non-significant increase over time (APC = 6.8%, p = 0.087). The proportion of time above 60 minutes for care provided by the transport team at the referral site significantly increased (APC = 7.4%, p = 0.016). Between 2008 and 2010, the use of mechanical ventilation during transports increased (APC = 36.4%, p = 0.578), then it showed a decreasing trend during the rest of the study period (APC = -7.2%, p = 0.068). The use of oxygen concentrations above 40% significantly decreased (APC = -9.5%, p = 0.043). The proportion of surfactant doses less than 150 mg/kg showed a decreasing trend (APC = -7.65%, p = 0.162), while doses above 180 mg/kg significantly increased over time (APC = 8.5%, p = 0.031). Neonatal long-term outcome indicators showed improving trends.

DISCUSSION: We observed relevant trends toward non-invasive approaches and improving outcomes.

CONCLUSION

Our study can facilitate the ongoing change of approach to care during postnatal transport, promote the development of relevant protocols and guidelines, which together can improve the outcome of preterm infants born outside tertiary care centers. Orv Hetil. 2023; 164(15): 571-576.
