Özet

Objective: The prone position was found to improve oxygenation and pulmonary functions in neonates receiving respiratory support. However, how this improvement changes brain tissue oxygenation has not been studied. We aimed to investigate how prone position effects regional cerebral oxygen saturation (rScO(2)) and cerebral fractional oxygen extraction (FOE) in preterm neonates during noninvasive ventilation (NIV). Methods: Preterm neonates < 37?weeks gestational age (GA) stable on NIV were enrolled. NIV was defined as nasal continues positive airway pressure or intermittent positive pressure ventilation via binasal prongs. Near infrared spectroscopy was used to measure rScO(2). Monitoring was started when the infant was lying supine for at least 1?h and continued at the same body position at least for 1?h. Later the infant was changed to prone position and monitored for additional 3?h. Arterial oxygen saturation (SO2) was also continuously monitored and FOE was calculated from rScO(2) and SO2. Results: Mean GA and birth weight of the cohort (n?=?32) were 30.63???3.09?weeks and 1459???581?g, respectively. There were 14 females and 18 males. Both SO2 (95???2.2% versus 96.2???1.9%, p?=?.001) and rScO(2) (79.2???3.4% versus 82.1???3.2%, p?
