Perinatal characteristics and delivery room management of infants born through MSAF.

The immediate delivery room (DR) management of non-vigorous (NV) infants with meconium stained amniotic fluid (MSAF) is controversial. A recent ILCOR suggestion is not to perform routine direct laryngoscopy (DL) with or without tracheal suctioning in NV infants. Our practice is to perform DL and endotracheal (ET) suctioning in targeted NV infants. The study objective was to describe the perinatal characteristics and DR Management of infants born through MSAF and admitted to the neonatal intensive care unit (NICU). Retrospective study evaluating the DR management of infants >35 weeks delivered through MSAF. Data retrieved included fetal heart rate abnormalities (FTHR), presence of thick/thin MSAF, DR management and postnatal course. 118 infants were resuscitated and directly admitted to the NICU, including 58 intubated for meconium, 29 receiving immediate PPV (n = 25) or CPAP (n = 4) and 31 (17%) initially stable developed delayed respiratory symptoms and administered CPAP. Sixty-four (35.2%) infants initially stable in the DR were subsequently admitted to NICU. ET suctioning was performed in 58/182 infants with meconium obtained in 41/58; meconium aspiration syndrome (MAS) was diagnosed in 21 infants. ET suctioning was positive in 10/21 cases. FHRT abnormalities (n = 50) were noted with thick meconium and associated with a 2.8-fold increased risk for meconium below the cords, and 3.1-fold increased risk of MAS. NV infants delivered through thick versus thin meconium were more likely to be intubated with a high yield of recovery. Serious pulmonary morbidity was uncommon. Most respiratory symptomatology were not related to MAS.
