background: the most common treatment for asthma is transferring the drug into the lungs by inhaler devices. besides, correct use of inhaled medication is required for effectiveness of pharmacotherapy. thus, it is necessary to train the patients how to use metered dose inhaler (mdi). this study aimed to determine the effect of training about mdi usage with or without spacer on maximum expirator...

The patients' inhalation flow pattern is one of the significant determinants for clinical performance of inhalation therapy. However, the development of inhalation flow meters for various inhalation devices has been unable to keep up with the increasing number of newly launched inhalation devices. In the present study, we developed simple attachment orifices for the inhalation flow pattern moni...

Inhalation injury is an acute respiratory tract insult caused by steam or toxic inhalants such as fumes, gases, and mists. Inhalation injury may occur without cutaneous burn injury, though the two injuries usually occur together. Despite increasing clinical interest in the problem of inhalation injury over the last few decades, the pathophysiology of inhalation injury remains poorly understood ...

Eucalyptus oil has been reported effective in reducing pain, swelling, and inflammation. This study aimed to investigate the effects of eucalyptus oil inhalation on pain and inflammatory responses after total knee replacement (TKR) surgery. Participants were randomized 1 : 1 to intervention group (eucalyptus inhalation group) or control group (almond oil inhalation group). Patients inhaled euca...

backgrounds: all of long-acting β2-agonists are beneficial in maintenance treatment of asthma but their use in relieving acute asthma attacks is not well known. the aim of this study was to compare rapid bronchodilatory effects of salmeterol and formoterol in patient with moderate to severe asthma. methods: it was a randomized, double blind, cross-over study on 60 patients with moderate to seve...

STUDY OBJECTIVES Inhalation of harmful substances is common in the workplace. The purpose of this study was to describe the epidemiology of fatal occupational inhalations in the United States. DESIGN Data from the Census of Fatal Occupational Injuries from 1992 to 1998 were analyzed. Information on demographic characteristics, occupation, and industry was used to calculate specific mortality ...

In establishing the guideline values for chemical contaminants in drinking water, the contribution of inhalation and dermal routes associated with showering/bathing needs to be evaluated. The present article reviews the current approaches available for evaluating the importance of inhalation and dermal routes of exposure to drinking water contaminants (DWCs) and integrates them within a 2-tier ...

PURPOSE The purpose of this study was to determine the influence of 40% nitrous oxide/60% oxygen inhalation with scavenging on the behavioral and physiological parameters during routine pediatric dental procedures. METHODS Twenty-two subjects, aged 60-116 months, were randomized into a double blind, cross-over study design and administered alternately either 40% nitrous oxide/60% oxygen or 10...

The bronchodilator response after four different modes of inhalation of 0.25 mg terbutaline from a Turbuhaler was assessed, in a double-blind cross-over study, of 14 asthmatic children aged 8-14 yrs (mean 11.6 yrs). The children inhaled as fast as possible (mean peak inspiratory flow rate = 53 l.min-1), because fast inhalations have been found to be more efficient than slow inhalations when the...

background the purpose of this study was to examine the relationship between the type of inhaled medication, length of use, dosing, the inhaler use technique and the severity and duration of disease on the dental caries of asthmatic patients. objectives in the present study, the frequency of dental caries in the asthmatic patients and control group was examined. in addition the possible associa...
