A long-term prospective assessment of home nebulizer treatment.

Forty-nine patients (15 asthma, mean FEV1/FVC 1.3/2.1; 34 COPD, mean FEV1/FVC 0.7/1.8) were referred for consideration of home nebulizer treatment. All were monitored for 2 weeks while using their usual inhaled treatment followed by 2 weeks using a 'Nebuhaler' spacer to deliver 1 mg of terbutaline and 80 micrograms of ipratoropium bromide (IB) four times daily. They then borrowed a System 22 nebulizer to self-administer salbutamol nebulizer solution (5 mg), IB unit dose vials (0.5 mg) or a mixture of these drugs four times daily for 1 month each. Both asthmatic and bronchitic patients had a significant rise in their mean daily peak flow rate (PFR) during home nebulizer treatment (P < 0.03) and the COPD patients also had a significant PFR rise during Nebuhaler treatment (P = 0.0004). The mean daily peak flow rates (PFR 1 min-1 were: baseline 179, Nebuhaler 195, salbutamol nebulizer 200, IB nebulizer 198, mixed nebulizer 216). Four patients failed to respond subjectively or objectively to either Nebuhaler or nebulizer treatment. Five patients responded well to Nebuhaler treatment and did not proceed to a home nebulizer trial. Eight further patients preferred Nebuhaler to nebulizer treatment or could not tolerate nebulizer treatment (two cases). Thirty-two patients requested home nebulizer treatment for long-term use (nine salbutamol, five IB, 18 mixture). Twenty-seven of these patients had an increased mean daily PFR (compared to their usual therapy) while using their chosen nebulized treatment. The mean increase in PFR for all 32 patients was 191 min-1 (11%).(ABSTRACT TRUNCATED AT 250 WORDS)
