Sustained Lung Inflation & Pulmonary Mechanics in Preterm Infant

Status Withdrawn

Clinical Trial Summary

Lung protection should start in the delivery room where, from the first breaths, the preterm infant can be helped to clear the lung fluid and to recruit alveolar spaces and establish the functional residual capacity (FRC). Sustained lung inflation (SLI) applied at birth in the delivery room has been demonstrated to lead to clearance of lung fluid and achievement of a precocious functional residual capacity (FRC) both in animal and human studies. SLI associated to an adequate positive end expiratory pressure (PEEP) may help the efficacy of the respiratory effort in lung of preterm infants at risk for respiratory distress syndrome (RDS) and reduce need of mechanical ventilation (MV). Further studies are required to evaluate the clinical utility of this maneuver. The ability to monitor what happens to the lungs while applying different recruitment maneuvers in preterm infants would allow the definition of a procedure that allows optimal assistance to improve the FRC. One promising approach is provided by the forced oscillation technique (FOT). During forced oscillations, a small amplitude sinusoidal pressure stimulus is applied to the airway opening and the mechanical response of the respiratory system is studied by means of the total respiratory input impedance (Zin). Zin is a complex number that can be expressed as real part, called resistance (Rrs), and imaginary part, called reactance (Xrs). Particularly, it has been recently shown that Xrs measured at 5 Hz is very sensible to changes in the mechanics of lung periphery and provides accurate information about lung volume recruitment and derecruitment. The main purpose of this work is to apply FOT to the assessment of lung function in newborns submitted to SLI at birth. The investigators hypothesized that the application in the delivery room of the SLI in the preterm infant is effective in achieving a greater FRC and therefore a greater value of Xrs compared to a control group not treated with the SLI.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
