ABSTRACT
INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) is a condition which requires, among others, the administration of bronchodilators and anti-inflammatory drugs to control the disease. They help to keep the airways clear and prevent the buildup of fluid and mucus. Inhalation is the most widely used form of administrating the medication because of its local and rapid action which normally is done by aerosol therapy. The objective of this study is to evaluate the effectiveness of two aerosol methods in clearing the airways of COPD patients, admitted with an exacerbation due to their disease. It also aims to evaluate its effects on the length of stay, oxygen saturation, dyspnea, autonomy and complications. METHODS: Randomized clinical trial. Traditional method (control group) and positive expiratory vibrating device (intervention group): two ways to deliver aerosol were compared. The following outcome variables were considered: length of stay, days of fever, oxygen saturation, need for NIV or VM, the basic activities of daily living index autonomy (Barthel), dyspnea (Borg scale) and peak-flow. RESULTS: 39 patients were included. Regarding hospital stay, patients in the intervention group spend an average of one day less in hospital. Also in this group there were fewer readmissions. No statistically significant differences were found in the remaining variables. CONCLUSIONS: The inhalation treatment with a vibrating device with positive exhalation, appears to reduce the length of stay and prevent readmissions. It is important to continue research on non-pharmacological interventions as to achieve the prevention of relapses.

Introducción. La enfermedad pulmonar obstructiva crónica (EPOC) es un trastorno que requiere la administración de medicación broncodilatadora y antiinflamatoria, entre otras, como uno de los cuidados de la enfermedad. Ayudan a mantener la limpieza de la vía aérea y a evitar recaídas por el acúmulo de secreciones. La vía inhalatoria, por su acción local y rápida, es la más usada para la aplicación de estos fármacos, que habitualmente se realiza en forma de aerosolterapia. El objetivo de este estudio es evaluar la eficacia en la limpieza de la vía aérea entre dos métodos de administración de aerosolterapia en pacientes con EPOC ingresados por una exacerbación de su enfermedad. También se pretende evaluar su efecto sobre los días de estancia, saturación de oxígeno, grado de disnea, autonomía y complicaciones. Método. Ensayo clínico aleatorizado. Se compararon dos formas de administrar aerosolterapia: método tradicional (grupo control) y dispositivo vibratorio con espiración positiva (grupo intervención). Se consideraron las siguientes variables resultado: días de estancia, días con fiebre, saturación de oxígeno, necesidad de VMNI o VM, las actividades básicas de la vida diaria, grado de autonomía (Barthel), grado de disnea (Escala de Borg) y pico flujo. Resultados. Se incluyeron 39 pacientes. En cuanto a los días de ingreso, los pacientes del grupo intervención presentaban de media un día menos de ingreso. También en este grupo hubo menos reingresos. No se encontraron diferencias estadísticamente significativas en el resto de las variables. Conclusiones. El tratamiento inhalatorio con un dispositivo vibratorio con espiración positiva parece reducir los días de estancia y prevenir los reingresos. Es importante seguir investigando sobre intervenciones no farmacológicas que consigan prevenir sus recaídas (AU)
