RESUMO

INTRODUCCIÓN: La prevalencia de hipertensión arterial neonatal en las unidades de cuidados intensivos neonatales (UCIN) varía entre el 3 y el 9%, sin embargo, no existe información actualizada de Latinoamérica. OBJETIVO: Estimar la prevalencia de hipertensión arterial y evaluar su asociación con causas previa mente relacionadas con esta condición. PACIENTES Y MÉTODO: Estudio transversal que incluyó a todos los niños internados en una UCIN durante un año, excluidos aquellos trasladados a cirugía cardio vascular. Se registraron variables maternas y neonatales, hipertensión arterial materna, vía de parto, edad gestacional, edad, sexo, peso de nacimiento, Apgar, antecedente de maduración pulmonar con corticoides y cateterismo de vasos umbilicales. Se consignó motivo de ingreso a UCIN, medicamen tos y complicaciones durante la hospitalización. La tensión arterial se registró con oscilómetro au tomatizado considerando hipertensión arterial según tablas para edad gestacional. La prevalencia se expresó como porcentaje (intervalo de confianza 95%, IC95%). La estadística descriptiva se presenta como mediana (rango) o frecuencia de presentación (porcentajes) y se buscó asociación con el Test de Wilcoxon, Chi2 o Fisher según correspondiera (p < 0,05). RESULTADOS: Se reclutaron 169 pacientes (60% sexo masculino). Edad gestacional: 38 semanas (rango 26-42), 38% prematuros. Peso 3.000 g (rango 545-4.950), 32% bajo peso. Ocho pacientes presentaron hipertensión arterial (prevalencia 4,7%, IC95% 2,4-9). La presencia de hipertensión arterial se asoció con prematurez (p = 0,0003), bajo peso (p = 0,01), maduración pulmonar con corticoides (p = 0,002), cateterismo umbilical (p = 0,03), uso de ≥ 2 drogas nefrotóxicas (p = 0,02), tratamiento con cafeína (p = 0,0001), injuria renal aguda (p = 0,02) e hipertensión intracraneal (p = 0,04). Solo un paciente requirió medicación antihiper- tensiva y en todos los casos se normalizó durante el seguimiento. CONCLUSIÓN: La prevalencia de hipertensión arterial neonatal fue de 4,7% y en todos los casos se presentó en niños prematuros con factores previamente reconocidos como asociados a esta condición.


INTRODUCTION: The prevalence of neonatal hypertension in neonatal intensive care units (NICU) ranges between 3 and 9%. However, there is no current data on Latin America. Objective: To estimate the prevalence of neonatal hypertension and to assess its association with causes previously related to this condi tion. PATIENTS AND METHOD: cross-sectional study. All patients admitted to the NICU during one year were included, excluding those transferred to the cardiovascular NICU. The following maternal and neonatal variables were registered: maternal arterial hypertension, type of delivery, gestational age, age, sex, birth weight, Apgar score, history of pulmonary maturation with corticosteroids, and umbilical vessel catheterization as well as the reason for admission to the NICU, medications, and complications during hospitalization. Blood pressure was measured with an automated oscillometric device, defining neonatal hypertension according to standards in gestational age. Prevalence was ex pressed as percentage (confidence interval 95%, CI95%). Descriptive data were reported as median (range) and frequency of presentation (percentage). Finally, we used the Wilcoxon, Chi2 o Fisher exact test to identify factors related to NH as applicable (p < 0.05). RESULTS: 169 patients were in cluded (60% males). Gestational age was 38 weeks (range 26-42 weeks), 38% were preterm. Birth weight was 3000 g (range 545-4950 g) and 32% presented low birth weight. Eight patients presented hypertension during hospitalization (4.7% prevalence, CI95% 2.4-9). The presence of hypertension was associated with prematurity (p = 0.0003), low birth weight (p = 0.01), prenatal corticosteroid treatment (p = 0.002), umbilical catheterization (p = 0.03), administration of ὅ 2 nephrotoxic drugs (p = 0.02), caffeine treatment (p = 0.0001), acute kidney injury (p = 0.02), and intracranial hyper tension (p = 0.04). Only one patient required antihypertensive pharmacologic treatment and in all cases, hypertension was resolved during follow-up. CONCLUSION: Prevalence of neonatal hypertension in our NICU was 4.7% and in all cases occurred in preterm newborns with previously recognized factors associated with this condition.

RESUMO

INTRODUCCION: La evidencia internacional demuestra que los niños con peso ≤1.500 gramos tienen mayor sobrevida y menos morbilidad cuando nacen en centro de nivel terciario con un alto censo diario en la unidad de cuidado intensivo neonatal (UCIN). También señalan que las unidades grandes son más costo-efectivas. Es importante establecer si en nuestro medio el costo de un sobreviviente < 1500 g se relaciona con el número de admisiones anuales de estos niños, ya que el sistema de salud, además de efectivo, debe ser sustentable.OBJETIVO: Establecer la relación entre costo-efectividad de la UCIN y número de admisiones de niños ≤1.500 gramos.METODOS: Se realizó un estudio multicéntrico retrospectivo observacional en 4 unidades de neonatología del sector público con índices de morbimortalidad neonatal hospitalaria equiparable. Se analizaron las historias clínicas de pacientes nacidos durante 2008 con peso ≤1.500 gramos. Los datos se recabaron en planillas estandarizadas e incluyeron los costos locales, valuados por precios de referencia y por costos reales, tanto de insumos y medicamentos como de estudios y horas de personal requeridas. Para establecer la costo-efectividad, el costo total de la UCIN fue calculado por sobreviviente con peso ≤1.500 gramos. La sobrevida y los costos fueron vinculados a las admisiones anuales para establecer la correlación entre número y efectividad/eficiencia de cada unidad.RESULTADOS: Se incluyó a 146 niños con un peso ≤1.500 gramos. La evaluación de costos mostró que en la UCIN con mayor número de ingresos el costo por paciente fue menor que en las UCIN chicas ($ 42.200 vs. $ 73.880 respectivamente).CONCLUSIONES: Estos datos confirman que el costo por sobreviviente es mayor cuando menor es el número de ingresos anuales de niños con peso < 1500 g. Para asegurar la sustentabilidad del sistema, sería más racional concentrar los ingresos de los < 1500 g en un menor número de unidades con mayor capacidad de internación.


INTRODUCTION: International evidence shows that very low birth weight (VLBW) infants have higher survival rates and fewer complications when born in large tertiary neonatal intensive care units (NICU) with a high daily census. These studies also show better cost-benefit ratios for larger units. It is important to establish whether the cost incurred for surviving VLBW infants in Argentina is related to the number of annual admissions, because health care needs to be both effective and sustainable.OBJECTIVE: To establish the relationship between cost-effectiveness of NICU and number of admissions of VLBW infants.METHODS: A multicenter, retrospective, observational study was performed in 4 NICUs of the public health care system with comparable neonatal hospital morbidity and mortality results. Clinical records were analyzed for VLBW infants born during 2008. Data were collected on standardized sheets and included local costs, with both actual and reference prices, for all disposables, drugs, studies and required personnel hours. To establish the cost-effectiveness, the total cost of the NICU was calculated per surviving VLBW infant. Survival and costs were linked to the number of annual admissions in each participating unit.RESULTS: 146 VLBW infants were included. The cost analysis showed that the NICU with the highest number of admissions had the lowest cost per survivor ($ 42.200 versus $ 73.880).CONCLUSIONS: The cost of a surviving VLBW infant is higher for NICUs with fewer annual admissions. To ensure sustainability of the health care system, it seems reasonable to concentrate the delivery of VLBW infants in fewer and larger units.
