The prehospital use of nebulized albuterol on patients with wheezing whose chief complaint is shortness of breath.

The use of prehospital nebulized beta-agonists has become widespread, and their safety and efficacy has been documented. Our purpose was to study their broadened use and determine their effectiveness in specific sub-sets of wheezing patients. We conducted a six and one-half month prospective study to determine the benefit of nebulized albuterol treatments on a variety of wheezing patients whose chief complaint to paramedics was shortness of breath. Sixty-two patients were enrolled in the study and were subdivided into four groups based on patient history; asthma, COPD, asthma & COPD (A/C), and non-Asthma/non-COPD (NANC). The effectiveness of the treatment was evaluated objectively by peak expiratory flow rates (PEFR) obtained before and immediately after treatment and subjectively by the patients' evaluation of their own dyspnea. Changes in PEFR were subjected to analysis by a paired T-test. Albuterol was effective in increasing the PEFR in patients with asthma, COPD and NANC. Patients with both asthma and COPD did not demonstrate increased PEFR after treatment. The majority of all patients were subjectively improved after nebulized albuterol treatments. We conclude that aerosolized albuterol is safe and effective in the prehospital treatment of patients complaining of dyspnea who are wheezing.
