About this trial

Around 50% of infants born extremely preterm develop a chronic lung disease known as bronchopulmonary dysplasia of which some infants will also develop pulmonary hypertension of which 50% of children will die before the age of 2. Physicians are currently limited in their ability to select the most appropriate oxygen targets that will improve outcomes in infants with this condition. This clinical trial will determine whether using different amounts of oxygen improve outcomes in infants with this disease.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Between 22w 0/7d and 31w 6/7d gestation at birth

Diagnosed with echocardiographic pulmonary hypertension (1) >20% flow of blood across the PDA from the pulmonary to arterial circulation, (2) end-systolic flattening of the interventricular septum (eccentricity index >1.3), or (3) right ventricular pressure estimates ≥ 35 mm Hg

Receiving supplemental oxygen

Have mature retinas

Disqualifiers

Major congenital anomalies

Trial design

Design model

Crossover

Treatments tested in this trial

  • higher oxygen saturation target using Nellcor pulse oximetry sensors

    Device

    The intervention will be a cross over exposure to the higher oxygen saturation target.

  • lower oxygen saturation target using Nellcor pulse oximetry sensors

    Device

    The intervention will be a cross over exposure to the lower oxygen saturation target.

Treatment groups

39 Participants
are divided into 2 treatment groups
Group A: Oxygen saturation target 92-95%Active comparator 1 intervention
Group B: Oxygen saturation target 95-98%Active comparator 1 intervention

Trial outcomes

Primary outcomes

1

Intermittent hypoxemia event duration

The average duration of time (in seconds) an infant's oxygen saturation decrease below 80%.

Time frame
From date of randomization until 3 weeks have elapsed or date of discharge, whichever came first

Secondary outcomes

1

Echocardiographic shunting

\>20% flow of blood across the PDA from the pulmonary to arterial circulation

Time frame
through study completion, 3 weeks from date of randomization until 3 weeks have elapsed or date of discharge, whichever came first
2

Echocardiographic interventricular septal flattening

End-systolic flattening of the interventricular septum (eccentricity index \>1.3)

Time frame
From date of randomization until 3 weeks have elapsed or date of discharge, whichever came first
3

Echocardiographic tricuspid regurgitation

Right ventricular pressure estimates

Time frame
From date of randomization until 3 weeks have elapsed or date of discharge, whichever came first
4

Intermittent hypoxemia frequency

Number of daily events during which an infant's oxygen saturation decreases below 80%

Time frame
From date of randomization until 3 weeks have elapsed or date of discharge, whichever came first
