Experimentell: Low Oxygen Strategy
Resuscitation was initiated with room air (21% O2) for LOX infants. Supplemental oxygen was given if 1) the heart rate (HR) was less than 100 bpm after 30 seconds of effective ventilation, 2) the lower limits of goal saturations were not met. Targeted goal Pre-ductal saturations after birth were derived by approximation of the interquartile values for healthy term infants as reported by Kamlin et al and Dawson et al.FiO2 was increased or decreased by 10% in 30 second intervals as needed. If HR < 60 bpm after 30 seconds of effective ventilation , FiO2 was increased to 100% until the heart rate was stabilized. Targeted Pre-ductal SpO2 After birth
10 min 85%-94% |

Aktiv komparator: Traditional Oxygen strategy ( TOX)
Resuscitation for TOX infants was started with 100% O2 and adjusted every 30 seconds by 10% to meet the target oxygen saturation range of 85-94%

Reduction in mean oxidative balance ratio at 1 hour of life
Tidsram: Cord blood and at 1 hour of life
|
Total hydroperoxide(TH), Biological antioxidant potential (BAP)were measured at 1 hour of life in all preterm infants.
Oxidative balance ratio was calculated from this formula.
Oxidative balance ratio = BAP/TH.
