PaO2/FiO2 Ratio as Predictor of Mortality in Neonates with Meconium Aspiration Syndrome.

Objectives: Partial arterial pressure of oxygen/fraction of oxygen in inspired air (PaO/FiO) ratio has been used as a predictor of outcome in some neonatal conditions, but has not been used in meconium aspiration syndrome (MAS). This study was conducted with the objective to study if the PaO/FiO ratio of < 200 at 6, 12, and 24 hours of life can predict mortality in neonates with MAS.

Study Design: Two hundred neonates with MAS were included in the study.
