Pulmonary Hypertension and Oxygen Saturation Targeting in Preterm Infants

Description

Infants born between 22.0 to 31.6 weeks’ gestational age with bronchopulmonary dysplasia associated pulmonary hypertension, are receiving supplemental oxygen, and have mature retinas will be randomized to SpO2 targets of either (1) 92-95% (control) or (2) 95-98% (intervention).

Using a cross over design with a 1:1 parallel allocation of infants randomized using a stratified permuted block design. Following 1week of exposure A, infants will cross over to exposure B for 1 week with a 1-week washout period. Bedside providers will follow pre-specified algorithms to maintain oxygen targets during the randomization period. Reports of oxygen saturation performance will also be provided to bedside providers through oxygen saturation histograms.
