Cerebral oxygenation among preterm infants is reduced in the prone position and is lower compared with age-matched term infants, according to study findings in Pediatrics.
Karinna L. Fyfe, BMedSc, of Monash University in Melbourne, Australia, and colleagues used daytime polysomnography to assess the effects of sleep state and position among 35 preterm infants and 17 term infants. Researchers measured tissue oxygenation index (TOI) and mean arterial pressure (MAP) at post-term age 2 to 4 weeks, 2 to 3 months and 5 to 6 months. Preterm study participants were born at 26 to 36 weeks gestation. Term study participants were born at 38 to 42 weeks gestation.
