Comparative Study Observational StudyThe precision and accuracy of Nellcor and Masimo oximeters at low oxygen saturations (70%) in newborn lambs.
Administration of oxygen in the delivery room is informed by oxygen saturation (SpO₂). An oxygen saturation range of 60%-70% is the threshold for administering oxygen in the first minutes after birth. The accuracy of newer generation oximeters to measure SpO₂ has not been compared against the 'gold standard', direct arterial blood oxygen saturation (SaO₂) when SaO₂ is low. The aim of this study was to determine the accuracy and precision of Nellcor and Masimo oximeters to measure SpO₂ when SaO₂ <70%. ⋯ At SaO₂<70%, both monitors overestimated oxygen saturation (SpO₂) compared with the gold standard. Both oximeters were equally inaccurate when SaO₂ was low.

The risk for hyperoxaemia after apnoea, bradycardia and hypoxaemia in preterm infants.
To investigate the occurrence and duration of oxygen saturation (SpO₂) ≥95%, after extra oxygen for apnoea, bradycardia, cyanosis (ABC), and the relation with the duration of bradycardia and/or SpO₂ ≤80%. ⋯ In preterm infants supported with nCPAP in the neonatal intensive care unit (NICU), SpO₂ ≥95% frequently occurred when oxygen was increased for ABCs and lasted longer than the bradycardia and SpO₂ ≤80%.

Comparative Study Observational StudyAre high flow nasal cannulae noisier than bubble CPAP for preterm infants?
Noise exposure in the neonatal intensive care unit is believed to be a risk factor for hearing loss in preterm neonates. Continuous positive airway pressure (CPAP) devices exceed recommended noise levels. High flow nasal cannulae (HFNC) are an increasingly popular alternative to CPAP for treating preterm infants, but there are no in vivo studies assessing noise production by HFNC. ⋯ At the gas flows studied, HFNC are not noisier than BCPAP for preterm infants.

Perinatal outcomes for extremely preterm babies in relation to place of birth in England: the EPICure 2 study.
Expertise and resources may be important determinants of outcome for extremely preterm babies. We evaluated the effect of place of birth and perinatal transfer on survival and neonatal morbidity within a prospective cohort of births between 22 and 26 weeks of gestation in England during 2006. ⋯ Despite national policy, only 56% of births between 22 and 26 weeks of gestation occurred in maternity services with a level 3 neonatal facility. Survival was significantly enhanced following birth in level 3 services, particularly those with high activity; this was not at the cost of increased neonatal morbidity.
