Surfactant delivery by aerosol inhalation – past, present, and future

Surfactant replacement therapy by nebulization to spontaneously breathing patients has been regarded as the Holy Grail since surfactant deficiency was first identified as the cause for neonatal respiratory distress syndrome. It avoids neonatal endotracheal intubation, a procedure that is often difficult and occasionally harmful. 

Towards a harmonized bronchopulmonary dysplasia definition: a study protocol for an international Delphi procedure

Bronchopulmonary dysplasia (BPD) remains the most common complication of preterm birth with lifelong consequences. Multiple BPD definitions are currently used in daily practice. Uniformity in defining BPD is important for clinical care, research and benchmarking. The aim of this Delphi procedure is to determine what clinicians and researchers consider the key features for defining BPD.

Lung Recruitment Before Surfactant Administration in Extremely Preterm Neonates: 2-Year Follow-Up of a Randomized Clinical Trial

To examine follow-up outcomes at corrected postnatal age (cPNA) 2 years of preterm infants previously enrolled in an RCT and treated with IN-REC-SUR-E or IN-SUR-E in 35 tertiary neonatal intensive care units.

Neonatal high-frequency oscillatory ventilation: where are we now?

High-frequency oscillatory ventilation (HFOV) is an established mode of respiratory support in the neonatal intensive care unit. Large clinical trial data is based on first intention use in preterm infants with acute respiratory distress syndrome. Clinical practice has evolved from this narrow population. HFOV is most often reserved for term and preterm infants with severe, and often complex, respiratory failure not responding to conventional modalities of respiratory support.

Unstable SpO2 in preterm infants: The key role of reduced ventilation to perfusion ratio

Instability of peripheral oxyhemoglobin saturation (SpO2) in preterm infants is correlated with late disability and is poorly understood. We hypothesised that a reduced ventilation to perfusion ratio (VA/Q) is the key predisposing factor for SpO2 instability.

The CIRCA DIEM Sub-Studies

A sub-study is an ‘add-on’ study that helps to answer specific questions within a larger research project. If you decide to participate in the CIRCA DIEM study, you or your child may be invited to take part in one of the CIRCA DIEM sub-studies.

The CIRCA DIEM study aims to establish if cycling environmental light and noise levels for premature infants during their initial hospital stay leads to earlier development of circadian (daily) rhythms and better outcomes for the preterm babies, including improved brain development.
