Adult Patients with Respiratory Distress: Current Evidence-based Recommendations for Prehospital Care
Introduction:We developed evidence-based recommendations for prehospital evaluation and treatment of adult patients with respiratory distress. These recommendations are compared with current protocols used by the 33 local emergency medical services agencies (LEMSA) in California.Methods:We performed a review of the evidence in the prehospital treatment of adult patients with respiratory distress. The quality of evidence was rated and used to form guidelines. We then compared the respiratory distress protocols of each of the 33 LEMSAs for consistency with these recommendations.Results:PICO (population/problem, intervention,...

Emergency Medication Access and Administration in Schools: A Focus on Epinephrine, Albuterol Inhalers, and Glucagon.
Abstract Access to emergency medications is a growing concern, particularly regarding the availability, safety, and use of these medications in schools. The purpose of this article is to report results not previously published from a national survey, specifically regarding the emergency use of epinephrine, albuterol inhalers, and glucagon. A nonexperimental, cross-sectional design was utilized for this descriptive study. An online survey was distributed to school nurses in 2015, and data from 6,298 school nurse respondents are presented in the analysis. Findings related to stock and student-specific emergency medi...

Commercial valved spacers versus home-made spacers for delivering bronchodilator therapy in pediatric acute asthma: a cost-effectiveness analysis.
Conclusions. The present study shows that in Colombia, an MIC, compared with commercial valved spacers, the use of home-made spacers for administering bronchodilator therapy is more cost-effective because it yields a similar probability of hospital admission at lower overall treatment costs.

Inhaled Isotonic Saline for Bronchiolitis
To the Editor I read with interest the meta-analysis by House et al showing that inhaled isotonic saline may have a beneficial therapeutic effect in bronchiolitis. While I am glad that they included our study in their analysis, I wish to point out that a novel element of our study was the use of a physiologic outcome measure to assess response to inhaled albuterol and isotonic saline, namely, respiratory inductance plethysmography (RIP). We observed no significant changes in the variables assessed by House et al (respiratory rate, oxygen saturation, and respiratory distress assessment index). However, 30% of albuterol-trea...

Asthma rescue treatments, time to reboot
Short-acting β2-agonists (SABAs) are inseparable from asthma. The word "Ventolin" has not only entered common language, but it profoundly symbolises relief from breathing distress, quite similar to how "nitroglycerin" supposedly rescues the heart. After the Second World War, synthetic corticosteroids revolutionised asthma management and gained nobility once an inhaled formulation was available . Intriguingly, despite the fact that chronic airway inflammation is inherent to the definition of asthma, as needed SABA was kept in guidelines as the preferred option for the mildest patients, and this u...

A Standard Guideline for Albuterol Weaning in Pediatric Patients Admitted with an Asthma Exacerbation
The average length of stay for a pediatric asthma exacerbation in the United States is about 2.2 days; as nearly 1 in 50 children with asthma is hospitalized with an exacerbation each year, this creates a substantial burden for patients and their families. A critical determinant of length of stay is the patient ’s albuterol wean; however, providers' approaches to weaning patients vary widely. The purpose of this quality improvement project was to reduce patients’ lengths of stay by implementing a guideline for weaning albuterol. (Source: Journal of Allergy and Clinical Immunology)

Indoor air pollution and respiratory health effects in inner city children with moderate to severe asthma
AbstractIndoor air pollution is increasingly recognized as a significant risk for respiratory illness, particularly in vulnerable populations. Thirty-six children aged 6 –14 years with moderate/severe asthma from inner city areas in New York City were studied for 2-week periods (summer and winter) using diaries and spirometry. Seven-day integrated indoor samples of PM10, PM2.5, trace elements, elemental/organic carbon, black carbon, and criteria gases (NO2, SO2, and O3) were collected in the subjects ’ residences. Asthma outcomes included cough and wheeze severity, albuterol use, and pulmonary function. Mi...

Exhaled nitric oxide (FeNO) is known to be a marker of TH2 airway inflammation, but several studies have shown that its value is affected by acute changes in airways caliber. Most of FeNO production occurs in the small conductive airways, but studies have investigated the relationship between FeNO and small airways caliber changes in asthma. Impulse oscillometry (IOS) unlike spirometry can assess the obstruction of small peripheral airwaysThe aim of this study was to evaluate whether changes in FeNO after acute bronchodilation test are associated with specific features of asthmatic patients.This observational retrospective...

As-needed ICS-LABA in Mild Asthma: What Does the Evidence Say?
AbstractFor the last three decades, the guidelines for asthma management have supported a stepwise therapeutic approach, based on the administration of controller medications (especially inhaled corticosteroids) complemented by on-demand use of rescue medication. Classically, the rescue medication recommended comprised short-acting β agonists (SABA). Some years ago, the use of Symbicort Maintenance and Reliever Therapy (SMART) demonstrated the benefits of a combination of budesonide-formoterol, an inhaled corticosteroid, and a long-acting β agonist (ICS-LABA) as rescue medication in moderate and severe asthma.

Albuterol and Pediatric Perioperative Respiratory Complications —Reply
In Reply We thank our colleagues for their interest in our study. We agree that many respiratory adverse events are common and minor and may have little effect on the patient ’s immediate clinical care. However, bronchospasm and laryngospasm are known to be a major cause of perioperative cardiac arrests, unplanned intensive care unit admissions, and neurological damage following anesthesia. The composite of these respiratory adverse events allows a standardized approac h to clinical trials and minimizes the potential for operator bias across treatment arms.

Albuterol and Pediatric Perioperative Respiratory Complications
To the Editor Perturbations of the respiratory system are common in children during general anesthesia, especially following tonsillectomy. Many complications (mild desaturations and airway obstruction) are relatively benign and easily remedied, although some, such as laryngospasm and bronchospasm, are severe and lead to rapid escalation of care in the perioperative environment. Fortunately, severe complications during pediatric anesthesia are uncommon. This rarity makes them hard to study owing to the prohibitive sample size needed to power such studies. Consequently (and to improve statistical efficiency), investigators ...
