Manejo perinatal en el límite de la viabilidad. Propuestas de abordaje en un hospital terciario / Perinatal management at the threshold of viability. An approach to practice at a tertiary care hospital

El objetivo de este artículo es realizar un protocolo de manejo perinatal para aquellos fetos/neonatos nacidos en el límite de la viabilidad (por debajo de la semana de gestación 256/7). Para ello se han revisado las principales publicaciones que hacen referencia a su asistencia en los últimos años. Partiendo de los resultados de morbimortalidad en nuestro hospital y en consenso con los neonatólogos, hemos establecido un protocolo de manejo en nuestro centro. Proponemos un esquema en el que según la edad gestacional y, en su defecto, el peso al nacimiento, establecemos cuál debe ser el tipo de vigilancia fetal anteparto, necesidad de transporte neonatal, administración de corticoides prenatales, vía del parto y tipo de reanimación al nacimiento. Todo ello se realiza en estrecha colaboración con los neonatólogos y haciendo partícipes a los progenitores en la toma de decisiones(AU)

This article aims to provide a clinical practice guideline on perinatal management in fetuses/neonates at the threshold of viability (below a gestational age of 256/7 weeks). We reviewed the main literature published in the last few years. On the basis of outcomes in morbidity and mortality in our hospital and consensus with neonatologists, we established a management protocol in our center. We propose a protocol in which, gestational age or, in its absence, birth weight are used to determine the kind of prenatal care provided, the need for neonatal transport, use of prenatal corticosteroids, mode of delivery and neonatal resuscitation. This protocol is applied in close collaboration with neonatologists and with parents’ participation in the decision to treat(AU)

Spontaneous triplet pregnancy complicated by uterus didelphys: a case report.

Uterine malformations and spontaneous triplet pregnancy are rare situations separately, and both are related to worse perinatal outcomes. In the 3 cases of combined triplet pregnancy and uterus didelphys previously published, at least 2 of the 3 fetuses died. Morbidity rates are also high. We report the case of a 24-year-old Caucasian woman with a uterus didelphys and two previous caesarean sections who carried a spontaneous triplet pregnancy. To our knowledge, this is the first case of a spontaneous triplet pregnancy in a uterus didelphys ever reported and the only one with uneventful perinatal outcome for all fetuses. Expectant management may be an alternative to embryo reduction to manage triplet pregnancies in a didelphys uterus, especially when this option is not considered. Nevertheless, there is not enough evidence to confirm which is the optimal management strategy, and more studies are needed.
