BACKGROUND Cystic fibrosis (CF) is characterized by chronic lung infection. Minimizing exposure to pathogens is important. Treating a CF pulmonary exacerbation includes nebulizer therapies, but little is known about pathogen exposure from nebulizer equipment in CF. OBJECTIVE To assess microbial growth in nebulizer equipment used by hospitalized CF patients. HYPOTHESIS The small-volume nebul...

this work aimed to prepare a nanoemulsion preparation containing budesonide and assess its aerodynamic behavior in comparison with suspension of budesonide. in-vitro aerodynamic performance of the corresponding micellar solution (ie. nanoemulsion preparation without oil) was investigated too. nanoemulsions of almond oil containing budesonide, as a hydrophobic model drug molecule, were prepared ...

BACKGROUND Blow-by, a common form of nebulizer therapy, in which the device is held away from a child's face, has been dismissed as ineffective because studies have demonstrated incremental aerosol drop-off with increasing distances from the face. Many of these studies do not take into account differences among nebulizer systems. Using common, commercially available nebulizer systems, we define...

BACKGROUND During operation of a jet nebulizer, the temperature of the nebulizer outlet could decrease by more than 10 degrees C, depending on the nebulizer type and operating conditions, such as driving flow rate and fill volume. The droplet size distribution generated from the nebulizer can be measured by a cascade impactor. However, when the cascade impactor is operated at ambient room tempe...

BACKGROUND An aerosol of budesonide inhalation suspension is delivered when used with various jet-nebulizer/compressor combinations. The constant introduction of new nebulizer/compressor combinations raises the question of whether the performance of these match the performance of existing devices. The aim of this study was to determine in vitro the inhaled mass and aerosol characteristics of bu...

  Background: Complications of Ventolin as the most common drug used for bronchiolitis are widely known. The present study was conducted to determine the efficacy of hypertonic saline 3%, compared with Ventolin, for treatment of acute bronchiolitis in children.   Methods : This double-blinded clinical trial study was conducted in Hajar Hospital, Shahrekord, Iran, from 2011 to 2012. A total of 7...

OBJECTIVE To compare the costs and effectiveness of albuterol by metered dose inhaler (MDI) and spacer versus nebulizer in young children with moderate and severe acute asthma. DESIGN Randomized, double-blind, placebo-controlled trial in an emergency department at a children's hospital. The participants were children 1 to 4 years of age with moderate to severe acute asthma. Patients assigned ...

The aim of our study was to verify if the type of nebulizer used could influence the results of aerosol therapy with beclomethasone dipropionate (BDP) in mild allergic asthma. We assigned 27 asthmatics allergic to grasses to 3 groups and treated them from May to July 1998 with aerosol therapy with BDP (800 microg) b. i. d. via nebulizer + pMDI salbutamol (200 microg) if necessary. Each group us...

We have assessed the physical and dynamic characteristics of 23 home jet nebulizer/compressor combinations currently available in the UK and Europe. The combinations were evaluated in terms of pressure-flow characteristics, aerosol mass distribution, volume output, electrical costs, and sound level. In addition, we determined the effect of nebulizer fill volume on aerosol mass distribution and ...

Nineteen outpatients with stable obstructive pulmonary disease (mean forced expiratory volume in one second [FEV1], 1.00 + 0.10 L) were evaluated for airway response to albuterol (salbutamol) administered by metered-dose inhaler and Bosch ultrasonic nebulizer (BUSN). Albuterol administered by metered-dose inhaler but not by nebulizer caused a significant increase in FEV1 and the mean forced exp...
