Las sibilancias recurrentes del pre escolar es una condición frecuente a la que se ve enfrentado el pediatra. La gran mayoría de estos pacientes presentan sibilancias en relación a infecciones respiratorias virales y solo una minoría de ellos tendrá diagnóstico de asma en la edad escolar. El enfrentamiento adecuado de estos niños se inicia con una detallada anamnesis y examen físico para descartar causas secundarias, lo que se complementa con algunos exámenes de laboratorio. La decisión de iniciar tratamiento de mantención dependerá principalmente de la frecuencia y gravedad de los episodios de sibilancias. Este tratamiento debe ser considerado como una prueba terapéutica, evitando su mantención por tiempos prolongados. Se recomienda el uso de corticoides inhalados en dosis bajas y realizar un seguimiento estrecho del paciente para objetivar la respuesta. En el caso de los episodios agudos los broncodilatadores son el tratamiento de elección, mientras que los corticoides sistémicos debieran reservarse solo para los casos severos o que requieren hospitalización.

Chilean SoCHinEP-SER consensus for asthma diagnosis and treatment in school age children Bronchial asthma is the most prevalent chronic condition among children, however, in Chile, it is underdiagnosed. This may be due to medical professionals failing to recognize the disease. It is essential to be aware of the symptoms and signs that are suggestive of the disease in order to begin an appropriate treatment to achieve disease control. Asthma must be suspected in school age children who present repeated episodes of bronchial obstruction. The diagnosis should be confirmed with lung function tests that demonstrate variable airflow obstruction with a positive bronchodilator response. Treatment is based on two fundamental pillars: education and pharmacological treatment. Educational activities must include: information about the disease and its treatment, regular monitoring of treatment adherence, teaching and reviewing the correct inhalation technique at every checkup, developing a personalized written action plan and scheduling regular follow-up appointments. The gold standard for treatment is maintenance inhaled corticosteroids, in the lowest possible dose that enables disease control. The goal of the treatment is to eliminate daily symptoms and asthma crisis. Therapy should be increased if control is not achieved, but before starting it, adherence to maintenance treatment, inhalation technique, presence of associated comorbidities and environmental exposure should be evaluated. In the mild patient, who is not receiving maintenance therapy, rescue treatment should be done with bronchodilators, always associated with inhaled corticosteroids. This consensus is a guide to improve the diagnosis, treatment and control of asthma in schoolchildren

Chilean consensus on management of asthma in preschool children Preschool wheezing is one of the most common presenting symptoms in pediatric practice. The vast majority of these patients present wheeze triggered by viral respiratory infections and only a minority of them will have asthma in school age. The evaluation of these children begin with a detailed clinical history and physical examination and standard laboratory tests to rule out secondary causes of wheezing. The decision for controlling therapy will depend on the frequency and severity of the wheezing episodes, but should always be considered as a treatment trial, avoiding prolonged periods of time. It is recommended to start with low doses of inhaled corticosteroids, evaluating treatment effect with a close follow up. Inhaled bronchodilators remain the treatment of choice in acute exacerbations of wheezing, systemic corticosteroids should be reserved for severe exacerbations in hospitalized patients.
