Desarrollo y validación de la Escala de Mortalidad Neonatal-9 México para predecir la mortalidad en neonatos críticamente enfermos

Prediction of mortality in very low birth weight neonates in Spain

“…It included 41 studies, with 50 models to be applied either prenatally or at different times during NICU admission. After this publication, at least 8 new predictive models have been described [23][24][25][26][27][28][29][30] in a recent systematic review [31]. The most commonly used mortality predictive models today include CRIB I and II [4,32] (year 1993 / United Kingdom-first 12 hours of life; 2003 / United Kingdom-first hour of life), DRAPER [6] (2000 / United Kingdom-childbirth start and admission to NICU), SNAP II and SNAPPE II [7] (2001 / Canada-first 12 hours of life), NEOCOSUR [33] (2005 / South America-before admission to NICU), NICHD models [5,24] (2008 / USA-at the beginning of mechanical ventilation; 2012 / USA-sequential: at birth, 7th day of life, 28 days of life and 36 weeks postmenstrual), SAW [34] (2008 / Egypt-48 hours of life) and PREM Score [35] (2010 / United Kingdom-prenatal and birth).…”

“…It has been hypothesized that maternal hypertension is an adaptive response that accelerates organ maturation in a fetus under stress, and could explain the lower mortality rate observed in this patient population. In other predicted models, the time period in which predictions were made included; the moment of birth [19,27], admission to NICU [6] or the first 12 hours of life [4,7]. In our project, we chose the first 24 hours of life, to better encompass the effect of severe respiratory distress syndrome (administration of surfactant and the use of mechanical ventilation), which increases mortality in the same way as the Canadian model [25] that also includes the first 24 hours of life.…”
