In all deliveries, meconium is present in 10% to 15% of amniotic fluid, and meconium aspiration syndrome (MAS) occurs in about 5% of newborns. The purpose of the study: (1) Neonatal MAS patients do not need resuscitation and positive pressure ventilation ratio; (2) evaluation of MAS neonatal clinical course and results of tracheal intubation and suction relationship; (3) after culture confirmed Incidence of amniotic fluid meconium contamination and MAS bacterial infection.
