AGUILAR, Adriana M. et al. Delivery room practices in infants born through meconium stained amniotic fluid: A national survey. Arch. argent. pediatr. [online]. 2010, vol.108, n.1, pp.31-39. ISSN 0325-0075.

Based on the results of two large RCTs, guidelines from NRP/AAP, ILCOR, ACOG, and from Argentinean scientific societies for intrapartum and postpartum management of pregnancies with Meconium Stained Amniotic Fluid (MSAF) have radically changed. However, there are no data as to current delivery room management of infants born through MSAF. Objectives. 1) To assess current delivery room approaches in infants born through MSAF in Argentina; 2) To evaluate the adherence to NRP/AAP recommendations among different centers. Design/methods. A 20-question anonymous web-mail based survey was sent to 121 institutions with ≥ 500 births a year. Results. The response rate was 63% representing 182,540 deliveries/year (26% of the total number of births in the country). Among the surveyed institutions, 24% were located in the city of Buenos Aires and 72% were public hospitals. Although no longer recommended, the following procedures are frequently performed: 1) Oro-nasopharingeal suctioning of meconiumstained infants before the delivery of the shoulders: sometimes, 50% of centers; always, 7 %. 2) Routine tracheal suctioning in vigorous infants, 30%. 3) Glottis exposure under laryngoscopy, 13 % for thin-consistency MSAF and 43% for thick-consistency MSAF. On the contrary, and although strongly recommended, only 69% of depressed infants have tracheal suctioning before ventilation. Up to 7% of centers perform other non recommended procedures such as chest compression and pressure over the larynx, to avoid breathing, and gastric lavage. Conclusions. In spite of not being currently recommended, intrapartum suction and postnatal intubation and suction of vigorous infants with MSAF are commonly performed in Argentina while in depressed newborns the latter procedure is not always carried out. Our study confirms the frequent gaps observed between scientific evidence, guidelines and clinical practice.
