Abstract
in English, Spanish

Last decades, a broad spectrum of inhaled devices (ID) had been developed to enhance efficacy and reduce adverse events. The correct use of IDs is a critical issue for controlling obstructive respiratory diseases. There is no recommendation on inhalation therapy in Argentina. This document aims to issue local recommendations about the prescription of IDs. Each device was reviewed regarding biophysical laws, indication, strength, limitations, correct technique of use, frequent mistakes, and device cleaning and maintenance. Nebulization should be restricted to drugs that are not available in other IDs (for example, for treatment of cystic fibrosis) or where other devices fail. Nebulization is not recommended during the SARS-CoV2 pandemic. A metered-dose inhaler must always be used with an aerochamber. Aerochambers reduce the incidence of adverse events and improve lung deposition. Metered-dose inhalers must be prescribed to patients who cannot generate a high inspiratory flow and dry powders to those who can generate an energetic inspiratory flow. We reviewed the use of different IDs in patients with cystic fibrosis and under mechanical ventilation. The individual choice of an ID will be based on several variables like clinical status, age, previous experience, patient preference, drug availability, and correct use of the device.

En las últimas décadas ha habido un importante desarrollo de dispositivos inhalados (DI) que permiten aumentar la eficacia de las drogas y disminuir los eventos adversos. Su correcto uso es de fundamental importancia para el control de las enfermedades respiratorias obstructivas. En la Argentina no existen recomendaciones locales sobre el uso de los DI. Se revisó la base biofísica, indicación, ventajas y limitaciones, técnica de correcto uso, errores frecuentes, mantenimiento y limpieza de cada DI. El uso de nebulizaciones ha quedado restringido a la administración de drogas que no están disponibles en otros DI (ejemplo: tratamiento de fibrosis quística), o ante la falla de los otros DI. No deben ser usados durante la pandemia de SARS-CoV2. Los inhaladores de dosis medida (aerosol) deben ser indicados siempre con aerocámaras (AC), las que reducen la incidencia de eventos adversos y aumentan el depósito de la droga en el pulmón. Son los dispositivos de elección junto a los inhaladores de polvo seco. Los aerosoles se deben usar en pacientes que no generan flujos inspiratorios altos. Los inhaladores de polvo seco deben recomendarse en aquellos que pueden realizar flujos inspiratorios enérgicos. Se revisaron los diferentes DI en fibrosis quística y en pacientes con asistencia respiratoria mecánica. La elección del DI dependerá de varios factores: situación clínica, edad, experiencia previa, preferencia del paciente, disponibilidad de la droga y entrenamiento alcanzado con el correcto uso.
