Comparing two methods for surfactant administration in preterm infants

Surfactant Administration by Insure or Thin Catheter

NA · Karolinska Institutet · NCT04445571

This study is testing a new way to give surfactant to preterm infants with breathing problems to see if it helps them breathe better and feel less pain compared to the usual method.

What this trial studies

This trial evaluates the efficacy and safety of surfactant administration using a thin catheter technique combined with analgesic premedication, compared to the established INSURE strategy. It focuses on preterm infants born before 32 weeks of gestation who are on CPAP and require surfactant treatment for respiratory distress syndrome (RDS). The study aims to assess outcomes such as oxygenation improvement, reduction in respiratory failure, and the need for mechanical ventilation within 48 hours post-procedure. Additionally, it will investigate safety aspects, including stress and pain levels during the administration process.

Who should consider this trial

Good fit: Ideal candidates for this study are infants born before 32 completed weeks of gestation who are on CPAP and show clinical signs of RDS requiring surfactant treatment.

Not a fit: Patients who may not benefit from this study include those requiring surfactant as part of delivery room resuscitation or those with congenital abnormalities affecting breathing.

Why it matters

Potential benefit: If successful, this study could enhance lung protective treatment strategies for preterm infants, potentially improving their oxygenation and reducing the need for invasive ventilation.

How similar studies have performed: Other studies have shown promising results with similar approaches, indicating potential for success in this trial.

Eligibility criteria

Inclusion Criteria:

* Infants born before 32 completed weeks of gestation on CPAP, with clinical and radiological signs of RDS and need for surfactant treatment.

Exclusion Criteria:

* Infants requiring surfactant as part of delivery room resuscitation are not eligible.

Infants will be excluded from the final analysis if they have a congenital abnormality or condition that might have an adverse effect on breathing or ventilation, including: congenital diaphragmatic hernia; tracheo-oesophageal fistula or cyanotic heart disease.
