Oxygenation Instability & Maturation of Control of Breathing in Premature

Status Completed

Clinical Trial Summary

Premature infants present with significant oxygenation instability in the form of frequent spontaneous episodes of hypoxemia during the first weeks after birth. These infants are also exposed to hyperoxemia. The objective of this study is to determine the extent to which exposure to frequent episodes of hypoxemia and hyperoxemia in extreme premature infants during the early stages of their evolving lung disease is associated with altered maturation and function of their respiratory control system. This study is part of the Prematurity-Related Ventilatory Control (Pre-Vent): Role in Respiratory Outcomes Clinical Research Centers (CRC) (U01) cooperative program of the National Heart Lung and Blood Institute (NHLBI) of the National Institutes of Health (NIH).

Clinical Trial Description

Most extreme premature infants present with respiratory failure due to altered lung function compounded by breathing instability due to an immature respiratory control function. Premature infants present with significant oxygenation instability in the form of frequent spontaneous episodes of hypoxemia during the first weeks after birth. As a result, these infants receive oxygen supplementation but this is often excessive and these infants are also exposed to hyperoxemia. The extent to which these episodes of hypoxemia or the exposure to hyperoxemia impact on the maturation and function of the control of breathing system in extreme premature infants during the evolving stages of their respiratory disease is unknown. This is a prospective study that will systematically evaluate such association in extreme premature infants. The main objective of this study is to determine the extent to which exposure to frequent episodes of hypoxemia and hyperoxemia in extreme premature infants during the early stages of their evolving lung disease is associated with altered maturation and function of their respiratory control system. This study is part of the Prematurity-Related Ventilatory Control (Pre-Vent): Role in Respiratory Outcomes Clinical Research Centers (CRC) (U01) cooperative program of the National Heart Lung and Blood Institute (NHLBI) of the National Institutes of Health (NIH). ;

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.
