Effects of Sustained Inflation or Positive Pressure Ventilation on the Release of Adrenomedullin in Preterm Infants with Respiratory Failure at Birth

What Was Tested

This randomized controlled trial paper looks at Adrenomedullin.

Therefore, in a cohort of low birth weight infants (LBW), the researchers investigated the effects of two different lung recruitment maneuvers, such as positive pressure ventilation (PPV) and sustained inflation (SI) on adrenomedullin (AM), a well-established lung-specific vasoactive agent.

Who Took Part

The study group was 44 infants.

PubMed tags the participants as both men and women.

AM assessment in urine samples was performed at 1-hour (URT1) and at 24-hour (URT2).

How the Study Was Run

The researchers set it up as a randomized study.

Because people in this Adrenomedullin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

This is a prospective case-control randomized study in 44 LBW infants spontaneously breathing with respiratory failure at birth requiring respiratory support.

LBW were randomized to receive PPV (n = 22) or SI (n = 22) support.

AM was measured from blood in samples collected at birth from arterial artery (BLT0) and at 1-hour (BLT1) and at 24-hour (BLT2) from peripheral venous site.
