In this issue of Pediatrics, Fyfe et al present convincing evidence that cerebral tissue oxygenation index (TOI) is lower in habitually supinesleeping preterm infants placed prone rather than supine, and that the cerebral TOI for preterm infants placed prone is lower than the TOI for term infants placed prone. Increased rates of sudden infant death syndrome (SIDS) among all infants sleeping pro...

UNLABELLED The predicitive values of fetal ultrasonography and magnetic resonance imaging are well established as antenatal outcome predictors in neonates with congenital diaphragmatic hernia (CHD). Postnatal outcome predictors remain elusive. THE AIM To evaluate the value of the oxygenation index (OI) as a predictor of postnatal survival. MATERIAL AND METHODS 58 newborns with congenital di...

OBJECTIVE To evaluate whether a formula could be derived using oxygen saturation (Spo2) to replace Pao2 that would allow identification of children with acute lung injury and acute respiratory distress syndrome. Definitions of acute lung injury and acute respiratory distress syndrome require arterial blood gases to determine the Pao2/Fio2 ratio of 300 (acute lung injury) and 200 (acute respirat...

OBJECTIVE To determine the relationship between contraction related changes in fetal heart rate and cerebral oxygenation measured by near-infrared spectroscopy during labour. STUDY DESIGN A specially designed optical probe was inserted through the dilated cervix and placed against the fetal head in 30 women during labour. Alterations in fetal heart rate during the final hour of the first stag...

The aim of this study was to explore the clinical value of ultrasonic monitoring in the assessment of pulmonary recruitment and the best positive end-expiratory pressure (PEEP).Between January 2015 and June 2017, 40 patients with acute respiratory distress syndrome in our hospital were randomly divided into 2 groups: ultrasound group (ULS group; n = 20) and oxygenation group (OXY group; n = 20)...

BACKGROUND AND PURPOSE In patients with subarachnoid hemorrhage, the assessment of cerebral autoregulation aids in prognosis as well as detection of vasospasm. Mx is a validated index of cerebral autoregulation based on measures of cerebral perfusion pressure and mean flow velocity on transcranial Doppler but is impractical for longer-term monitoring. Near-infrared spectroscopy is noninvasive a...
