Insights
Early surfactant treatment in preterm infants with severe respiratory distress syndrome (RDS) showed no long-term neurodevelopmental or pulmonary advantage. Improvement in gas exchange after intubation can be awaited before surfactant administration.
Area of Science:
- Neonatal Medicine
- Pediatric Pulmonology
- Developmental Pediatrics
Background:
- Respiratory distress syndrome (RDS) is a common condition in preterm infants.
- Surfactant replacement therapy is a cornerstone in managing RDS.
- The optimal timing for surfactant administration remains a subject of investigation.
Purpose of the Study:
- To compare neurodevelopmental outcomes and pulmonary morbidity at two years of age.
- To evaluate the effects of early versus late surfactant treatment in intubated preterm infants with severe RDS.
Main Methods:
- A controlled trial involving 185 preterm infants (27-32 weeks gestation) receiving either early or late surfactant treatment.
- Standardized follow-up included medical history, pulmonary morbidity assessment, and neurodevelopmental evaluation using the Griffiths scales at two years.
- Groups were defined by surfactant administration time: early (31 ± 19 min) versus late (202 ± 80 min) after intubation.
Main Results:
- Neurobehavioral and motor development were comparable between early and late surfactant treatment groups.
- Medical history and actual morbidity at follow-up did not differ significantly.
- The early treatment group showed a delay in the 'personal social' subscale of the Griffiths test and a higher rate of increased muscular tone.
Conclusions:
- Immediate surfactant administration after intubation in preterm infants with RDS offers no clear long-term advantage in morbidity or neurological development.
- These findings support a strategy of awaiting improvement in gas exchange before administering surfactant.
- The results align with previous findings on morbidity at discharge, suggesting a conservative approach to surfactant timing.
Aim:
To investigate whether neurodevelopmental outcome or pulmonary morbidity at age two years might be different after early versus late surfactant treatment in intubated preterm infants with severe respiratory distress syndrome (RDS).
Methods:
In 185 ex-preterm infants of 27-32 completed weeks of gestation, who were enrolled in a controlled trial of early versus late surfactant treatment (31 +/- 19 min vs. 202 +/- 80 min, respectively), a standardized follow up of medical history, pulmonary morbidity and neurodevelopmental outcome using the Griffiths scales were carried out.
Results:
Neurobehavioural and motor development was comparable in both groups, as was medical history and actual morbidity. However, in the early treatment group a delay in the subscale 'personal social' of the Griffiths test and in one 'milestone' of motor development (rolling over from supine to prone) was noticed, and the rate of increased muscular tone was significantly higher.
Conclusion:
In terms of long-term morbidity or neurological development there is no obvious advantage of an immediate surfactant administration after intubation in preterm infants with RDS. This is in line with our results published earlier on morbidity at discharge, so improvement of gas exchange after intubation can first be awaited before surfactant is indicated.
