Design Data from 768 infants <3dos weeks gestation from 8 randomised controlled trials (RCTs) of lower (?0.3) versus higher (?0.6) initial inspiratory fractions of oxygen (FiO2) for resuscitation, were examined.
Results 5 min SpO2 data were obtained from 706 (92%) infants. Only 159 (23%) infants met SpO2 study targets and 323 (46%) did not reach SpO280%. Pooled data showed decreased likelihood of reaching SpO280% if resuscitation was initiated with FiO2 <0.3 (OR 2.63, 95% CI 1.21 to 5.74, p<0.05). SpO2 <80% was associated with lower heart rates (mean difference ?8.37, 95% CI ? to –1.01, *p<0.05) and after accounting for confounders, with IVH (OR 2.04, 95% CI 1.01 to 4.11, p<0.05). Bradycardia (heart rate <100 bpm) at 5 min increased risk of death (OR 4.57, 95% CI 1.62 to , p<0.05). Taking into account confounders including gestation, birth weight and 5 min bradycardia, risk of death was significantly increased with time taken to reach SpO280%.
Conclusion Not reaching SpO280% at 5 min is associated with adverse outcomes, including IVH. Whether this is because of infant illness or the amount of oxygen that is administered during stabilisation is uncertain and needs to be examined in randomised trials
