ABSTRACT
A review of two previously published studies done at the University Hospital of the West Indies, an unpublished study and annual perinatal statistics was conducted to detect trends in the mortality of very low birthweight infants at the institution over four decades. Mortality decreased from 54% to 38% over the time period, the decrease was greater for infants weighing 1001-1500 g (40%) than those weighing ≤ 1000 g (28%). Despite increased access to mechanical ventilation over time, there was no appreciable decrease in mortality for infants weighing ≤ 750 g. There was a statistically significant decrease in mortality with increasing birthweight for the time period 1987-2002, p < 0.001. The mean ± SD weight of survivors 1.18 ± 0.24 kg was significantly greater than that for non-survivors 0.89 ± 0.21 kg for the same period. Further decrease in mortality of very low birthweight infants will involve measures aimed at decreasing mortality in infants weighing ≤ 750 g and increasing the availability of parenteral nutrition and the accessibility of surfactant.
RESUMEN
Se llevó a cabo un examen de dos estudios previamente publicados realizados en el Hospital Universitario de West Indies, un estudio inédito, y las estadísticas perinatales anuales, con el propósito de detectar las tendencias en la mortalidad de los neonatos de muy bajo peso al nacer en la institución en un período de cuatro décadas. La mortalidad disminuyó de 54% a 38% durante ese periodo de tiempo. La disminución fue mayor para los infantes que pesaban 1001-1500 g (40%) que para aquellos que pesaban ≤ 1000 g (28%). A pesar del aumento del acceso a la ventilación mecánica con el tiempo, no se produjo una disminución apreciable en la mortalidad de infantes cuyo peso era ≤ 750 g. Hubo una disminución estadísticamente significativa de la mortalidad en relación con el aumento del peso en el período de 1987-2002, p < 0.001. El peso ± SD promedio de los sobrevivientes (1.18 ± 0.24 kg) fue significativamente mayor que el de los no sobrevivientes (0.89 ± 0.21 kg) para el mismo periodo. Una ulterior disminución de la mortalidad en neonatos de muy bajo peso al nacer implicará medidas encaminadas a disminuir la mortalidad en neonatos de peso ≤ 750 g y a aumentar la disponibilidad de la nutrición parenteral y la accesibilidad de los surfactantes.
