Objetivo

Conocer la incidencia de hospitalización por bronquiolitis en nuestro medio, analizar las malformaciones neonatales graves como factor de riesgo de ingreso porbronquiolitis y establecer las variables disponibles en elmomento del ingreso por bronquiolitis que se asocian auna peor evolución.

Pacientes y método

Estudio de incidencia de ingreso por bronquiolitis enpoblación general y en niños con malformaciones neonatales graves. Estudio descriptivo y analítico sobre las características clínicas disponibles en el ingreso por bronquiolitis que predicen una peor evolución, sobre 61 niñosnacidos en el Hospital de Medina del Campo. Todos cumplían los criterios de McConnochie y se clasificaron segúnla evolución en leve, moderado o grave.

Resultados

La incidencia acumulada anual de ingreso por bronquiolitis fue de 1,79 % (intervalo de confianza [IC] del 95 %,1,–2,30). La incidencia de hospitalización fue significativamente mayor en los niños con antecedentes de malformaciones neonatales graves (13,11 %) que en los sanos(1,59 %) (RR, 8,26; IC 95 %, 4,–16,02). La edad fue significativamente menor (p=0,0056) en el grupo grave (mediana, 1,0; cuartiles, 1,–2,75) que en los grupos moderado(mediana, 5,0; cuartiles, 2,–8,0) y leve (mediana, 5,5; cuar-tiles, 3,–9,0). Tomando como referencia la evolución levese relacionaron con una evolución moderada-grave el rechazo de tomas (OR, 4,08; IC 95 %, 1,–16,80), los vómitos (OR, 4,22; IC 95 %, 1,–25,30) y la espiración alargada(OR, 5,35; IC 95 %, 1,–24,30). Tomando como referenciael grupo levemoderado se relacionaron con evolucióngrave la presencia de vómitos (p=0,004), los crepitantes(p=0,002), la disminución de ventilación (p<0,001) y la condensación radiológica (p=0,017).

Conclusiones

La incidencia de ingreso por bronquiolitis se situó encifras similares a las de otros países. Las variables que presentes en el momento del ingreso se asociaron a una peorevolución fueron: edad inferior a 3 meses, vómitos, rechazo de tomas, espiración alargada, crepitantes, disminuciónde ventilación y condensación radiológica. Las malformaciones neonatales graves son un importante factor de riesgo para requerir ingreso por bronquiolitis.

Objective

To determine the incidence of hospital admissions forbronchiolitis in our environment, to analyze the importance of neonatal malformations as a risk factor for hospitalization for bronchiolitis and to establish the variables available on admission that are associated with aworse evolution.

Design and patiens

Descriptive study of admissions for bronchiolitis in asample of the general population and in children with severe neonatal malformations. Descriptive and analyticalstudy of the clinical characteristics available on admissionfor bronchiolitis that predict a worse evolution. Sixtyonechildren born at the Medina del Campo Hospital in Spainwere studied. All the children were diagnosed according to McConnochie's criteria and classified into three groupsaccording to evolution (mild, moderate and severe).

Results

The annual cumulative incidence of admissions due tobronchiolitis was 1.79 % (95 % CI, –2.30). This incidence was higher in children with a history of severe neonatalmalformations (13.11 %) than in those without malformations (1.59 %) (RR58.26; CI 95 %, –16.02). Childrenwith severe bronchiolitis were younger (p50.0056; median 1.0, quartiles –2.75) than those with moderatebronchiolitis (median 5.0; quartiles –8.0) or mild bronchiolitis (median 5.5; quartiles –9.0). Using the groupwith mild bronchiolitis as reference, diminished appetite(OR54.08; 95 % CI, –16.80), vomiting (OR54.22; 95 %CI, –25.30) and prolonged expiration (OR55.35, 95 %CI, –24.30) were associated with moderate-severe evolution. Using the mildmoderate group as reference, vomiting (p50.004), crepitant rales (p50.002), decreasedventilation (p,0.001) and radiological consolidations(p50.017) were associated with severe evolution.

Conclusions

The incidence of hospital admission for bronchiolitis inour environment was similar to data reported from othercountries. Variables available at admission predicting aworse evolution were age lower than 3 months, vomiting,diminished appetite, prolonged expiration, crepitant rales,decreased ventilation and radiological consolidations. Severe neonatal malformations were an important risk factorfor hospital admission due to bronchiolitis.
