ABSTRACT
A retrospective analysis of the outcome of inborn very low birthweight infants admitted to the neonatal unit of the University Hospital of the West Indies pre- (period 1) and post- (period 2) establishment of a neonatal intensive care unit was conducted. During the study, 250 infants were admitted to the neonatal unit, 132 (53) during period 1 and 118 (47) during period 2. There was improved survival during period 2 when 81 (69) infants survived compared to period 1 when 73 (55) survived (p = 0.02). This increased survival was due to an increase in survival of infants weighing 750-999g in period 2 when 17 (65) infants survived compared to 9 (29) in period 1 (p < 0.05). There was an increase in the number of infants ventilated in period 2, 39 (33) compared to 12 (9) period 1 (p < 0.001). Infants who were ventilated in period 2 were less likely to die than those ventilated in period 1 (OR 0.05, CI 0.01, 0.66). After controlling for gender, weight, gestational age and ventilation, infants born in the second time period were less likely to die than those born in the first time period (OR 0.33, CI 0.14, 0.76). The establishment of a neonatal intensive care unit has resulted in improved survival of very low birthweight infants; further improvement in survival of these infants will be dependent on increased accessibility to surfactant therapy, initiation of total parenteral nutrition and availability of trained personnel.
RESUMEN
Se llevó a cabo un análisis retrospectivo del estado clínico de los recién nacidos con peso extremadamente bajo, ingresados en la unidad neonatal del Hospital Universitario de West Indies, antes (período 1) y después (período 2) del establecimiento de una unidad neonatal de cuidados intensivos. Durante el estudio, 250 recién nacidos fueron ingresados en la unidad neonatal 132 (53%) durante el periodo 1 y 118 (47%) durante el periodo 2. En este segundo período, se produjo un aumento de la supervivencia, al sobrevivir 81 (69%) recién nacidos, en contraste con el primer período, en el que sobrevivieron 73 (55%) infantes (p = 0.02). Este aumento se debió a un incremento en la supervivencia de los infantes que pesaban 750 – 999 g en el período 2, en el que 17 (65%) recién nacidos sobrevivieron, en comparación con el 9 (29%) en periodo 1 (p <0.05). Hubo un aumento en el número de recién nacidos ventilados en el período 1(OR 0.05, CI 0.01, 0.66). Después de ajustar por el sexo, peso, edad gestacional y ventilación, los infantes nacidos en el segundo período de tiempo eran menos propensos a morir que los ventilados en el primer período (OR 0.33, CI 0.14 – 0.76). El establecimiento de una unidad neonatal de cuidados intensivos ha traído como resultado un mejoramiento en la supervivencia de los recién nacidos con un peso extremadamente bajo al nacer. El mejoramiento ulterior de estos infantes dependerá de una mayor accesibilidad a la terapia surfactante, la iniciación de la nutrición parenteral total, y la disponibilidad de personal calificado.
