Cuidados respiratorios intermedios: un año de experiencia

Characteristics of asthma patients admitted to an intermediate respiratory care unit

INTRODUCTION

Intermediate respiratory care units (IRCU) provide continuous monitoring and non-invasive mechanical ventilation (NIMV) in patients with severe respiratory failure who are usually admitted to intensive care units (ICU). The usefulness of IRCU in managing severe asthma exacerbations has never been evaluated.

METHODS

Clinical data were prospectively and systematically compiled from patients admitted to the IRCU with a principal diagnosis of bronchial asthma exacerbation. We assessed therapeutic failure (intubation or exitus) and patient evolution up until 6 months after discharge compared with a group of patients admitted to a conventional hospital ward, paired for age and sex, and with the same principal diagnosis.

RESULTS

A total of 74 asthma patients were included (37 admitted to IRCU and 37 to the hospital ward) with a mean age (±SD) of 58±20, who were predominantly women (67%), with previous diagnosis of asthma and persistent asthma treatment. The main cause of admittance to the IRCU was severe respiratory failure. The patients who were admitted to the IRCU presented more radiological affectation (alveolar infiltrates) and had significantly higher pCO(2). Ten patients admitted to the IRCU required NIMV. There were no differences between the two groups regarding either therapeutic failure or the 6-month follow-up after discharge.

CONCLUSIONS

Patients with severe asthma exacerbations can be managed in an IRCU while avoiding hospitalization in an ICU and demonstrating a prognosis similar to milder exacerbations treated in conventional hospital wards.

The present study analyses the works published in Archivos de Bronconeumología from June 2008 to November 2009 that mention sleep disorders, non-invasive ventilation and critical care. The methodology used was to analyse the objectives of the works submitted, with their main results and the conclusions suggested by the authors, often putting forward the possibility of conducting new research studies. The review no only includes original articles but is also a reflection on the editorials, special articles and review works.
