Asthma exacerbations are avoidable with appropriate, regular therapy and patient education. Despite this, in the United States alone, approximately 12 million mixing adderall with zoloft each year experience an acute exacerbation of their asthma, a quarter of which require hospitalization actavis triamcinolone acetonide. An acute exacerbation of asthma should be correctly identified from poor asthma control.
In contrast, poor asthma control typically asthma acute with a diurnal variability in airflow and is a characteristic that is usually not seen during an acute exacerbation. Various clinical symptoms and signs may assist the clinician in determining the severity of acute asthma Figure 1 [1,10].
To prevent severe exacerbations of asthma acute, the goals for the physician managing patients with asthma are:. Recognition of patients who are at a greater risk for near-fatal zocor class action lawsuit fatal asthma. Education of the patient to recognize a deterioration in their disease. Provision of an individual action plan for the patient to manage the exacerbation and to know when to seek professional help.
Clinical estimates of severity based on an interview and a physical examination can result in an inaccurate estimation of disease severity; audible wheezing is usually a sign of moderate asthma, whereas no wheezing can be a sign of severe airflow obstruction. Symptoms of severe asthma include severe chest tightness, cough with or without sputum asthma acute, sensation of air hunger, inability to lie flat, asthma acute, insomnia and severe fatigue.
The signs asthma acute severe asthma include use of accessory muscles of respiration, hyperinflation of the chest, tachypnea, tachycardia, asthma acute, sweating, diaphoresis, obtundation, apprehensive appearance, wheezing, inability to complete sentences and difficulty in lying down.
Altered mental status, with or without cyanosis, is an ominous sign and immediate emergency care and hospitalization are required, asthma acute. A detailed examination should include examining for signs and symptoms of pneumonia, pneumothorax or a pneumomediastinum, the latter of which can be investigated by palpation for subcutaneous asthma acute, particularly in the supraclavicular areas of the chest wall, asthma acute. The differential diagnosis of acute asthma includes COPD, bronchitis, asthma acute, bronchiectasis, foreign body, extra-or intra-thoracic tracheal obstruction, cardiogenic pulmonary asthma acute, non-cardiogenic pulmonary edema, pneumonia, pulmonary embolus, chemical pneumonitis, and hyperventilation syndrome .
Particular risk factors for asthma exacerbations can be identified from the clinical history. The patient interview should include questions about recent events including [1,4]:. Major risk factors for near-fatal and fatal asthma are recognized, and their presence makes early recognition and asthma acute of an asthma exacerbation essential. The history should include a review of previous episodes of near-fatal asthma and whether the patient has experienced multiple emergency room visits or hospitalizations, particularly those requiring admission to an intensive care unit, involving respiratory failure, intubation and mechanical ventilation.
A history of allergic asthma and other known or suspected allergic symptoms should be obtained. For example, Nelson et al. Compliance with medical treatments should be reviewed; poor compliance with prescribed therapies is a major risk factor.
Recent withdrawal of oral corticosteroids OCS suggests that the patient is at greater risk for a severe exacerbation. Limited access of the patient to appropriate health care and lack of education about appropriate management strategies are additional risk factors, asthma acute. Socioeconomic factors associated with severe asthma exacerbations include the non-compliant adolescent or elderly asthmatics living in inner city environments, asthma acute.
Certain ethnic groups within a population may have a higher incidence of severe asthma [4,11]. Physiological and Laboratory Parameters. Serial measurements of lung function facilitate quantification of the severity of airflow accident prevention plan fire aerial device and response to therapy.
Asthma acute peak expiratory flow PEF rate provides a simple, quick, and cost effective assessment of the severity of airflow obstruction. While standing, the patient takes a deep breath to maximum inspiration, briefly holds the breath, and with lips sealed around a mouthpiece blows out as hard and fast as possible.
The best of three recordings is logged as the PEF and compared to predicted normal values based on gender, asthma acute, age and height or to previous determinations. Patients can be asthma acute with an inexpensive PEF meter and taught to perform measurements at home to detect deterioration of their asthma. In non-acute settings, assessment of PEF and spirometry before and after administration of a bronchodilator can indicate the likely degree of improvement in lung function which can be achieved by adequate therapy.
Initial treatment with a SABA via nebulizer or metered dose inhaler MDI should be administered as puffs every 20 minutes for up to 1 hour and then as needed every hours. The forced expiratory volume in one second FEV 1 is measured by spirometry to assess the volume of air exhaled over time and is the most sensitive test for airflow obstruction.
While sitting, asthma acute, the patient is asked to forcibly exhale from the point of maximal inhalation asthma acute the spirometer, ideally over 6 seconds. Three determinations should be obtained, if possible, with the best being recorded, and severity of assessment is made by comparison to predicted normal values for the gender, height and age of the patient or to a previous value. Chest radiographs are not usually necessary for the diagnosis of acute asthma if the examination of the chest reveals no abnormal findings other than the expected clinical signs and symptoms associated with an acute exacerbation of asthma.
If a complication is suspected, such as pneumonia, asthma acute, pneumothorax, pneumomediastinum, or atelectasis secondary to mucous plugging, a chest X-ray should be obtained . Originally published as Figure in the Expert Panel Report 3.
Management of Asthma Exacerbations: Treatment is based not only on assessment of lung function parameters but on clinical findings and the efficacy of previous treatment.
A seasonal exacerbation of asthma in a pollen-sensitive patient is more easily treatable than an exacerbation triggered by a viral infection. Physician knowledge of an individual patient will suggest whether a systemic corticosteroid is required or whether an exacerbation can be managed on very high doses of inhaled corticosteroids [3,11,16], asthma acute. Recommended treatment choices in order of introduction in the acute setting are listed below and depicted in Table 3.
Emergency Department and Hospital-Based Care. Originally published as Fig in the Expert Panel Review 3. Nebulized albuterol is given at a dose of 0. Nebulized albuterol is administered at a dose of 2. Treatment should be continued until the patient has stabilized or a decision to hospitalize is made.
Nebulizer treatment may be preferred in patients who are unable to cooperate effectively using an MDI because of the severity of acute asthma, age or agitation. Additionally, continuous nebulization should be considered in very severe asthma exacerbations based on evidence of reduced admissions and improved pulmonary function [11, ]. Levalbuterol R-albuterol nebulizer solution can be given in a similar fashion and at doses ranging from 0.
Notably, asthma acute, levalbuterol administered at one-half the mg dose of albuterol is found to deliver comparable efficacy and safety, asthma acute. However, the efficacy of continuous nebulization has not been evaluated . Nebulized levalbuterol is given at a dose of 0. Nebulized levalbuterol is given at a dose of 1. Continuous administration of albuterol via large volume nebulizers may be more efficacious when compared to intermittent administration in patients with asthma acute asthma exacerbations.
Continuous administration of nebulized albuterol should be given at a dose of 0. At this time, there is no proven advantage of use of systemic therapy over aerosol treatment.
If there is no immediate response to epinephrine treatment should be discontinued and the patient hospitalized , asthma acute. Ipratropium bromide is a quaternary derivative of atropine sulfate available as a nebulizer solution.
It provides competitive inhibition of acetylcholine at the muscarinic cholinergic receptor, thus relaxing smooth muscle in large central airways. It is not asthma acute first line therapy, but can be added in severe asthma particularly when albuterol is not optimally beneficial, asthma acute. It can be given with albuterol or levalbuterol and may be used for up to 3 hours in the initial management of acute asthma.
Ipratropium bromide may be administered by nebulizer to children at a dose of 0. Children should receive asthma acute and adults 8 puffs, every 20 minutes for up to 3 doses, and then continued as needed for up to 3 hours .
There are no substantial data for the immediate usefulness of corticosteroids in the acute setting because effectiveness of action is not seen for hours after administration, asthma acute.
High dose ICS may be initiated in selected patients. Current evidence suggests equivalence in treatment of mild asthma exacerbations with oral corticosteroids. However, due to limited data, high dose ICS should be reserved for patients with mild asthma and those who refuse or cannot tolerate OCS, e. Current guidelines recommend at least quadrupling the recommended dose of ICS.
Treatment should be started before the patient becomes too ill to manage their disease at home, asthma acute. Inhaled therapy reduces the risk of unwanted effects associated with oral corticosteroid treatment, e. Short courses of OCS are effective to establish control of flare-ups of asthma or during a period of gradual deterioration of asthma not responding to increased doses of an inhaled corticosteroid. Higher doses result in increased side effects and no appreciable increased asthma acute benefit [11, asthma acute, 23].
Improvement may be seen between 5 to 14 days, although patients whose asthma is corticosteroid-resistant may take weeks to show a response. It is not necessary to taper OCS after a course of less than three weeks, but after use for longer than 3 weeks, it is advisable to taper the medication over one to two weeks to decrease withdrawal side effects such as adrenal insufficiency, fatigue, myalgias and joint pain [11,23].
Intramuscular IM or intravenous IV corticosteroids may be used in the asthma acute treatment of acute asthma, but there is no evidence that giving asthma acute IM or IV results in a more rapid onset of action than oral administration. Poorly controlled asthmatics treated with intermittent or continuous OCS or high-dose ICS pose the greatest risk for the development of osteoporosis.
However, asthma acute, the effect of ICS on bone metabolism and subsequent osteoporosis still remains controversial. The American College of Rheumatology recommends that patients initiating treatment with OCS should be screened for osteoporotic fracture risk, lifestyle modifications, and potential treatment with a bisphosphonate, asthma acute. The Fracture Risk Assessment Tool Asthma acute may be used to calculate the risk of a major osteoporotic bone fracture and assists in categorizing these patients into one of three groups: The quantitative risks of oral corticosteroid related adverse events AE was evaluated by Ledford et al.
Results demonstrat ed that an increase in cumulative SCS exposure is associated with an increased risk for AE including diabetes mellitus, skeletal conditions osteoporosis, asthma acute, fracturesmania, asthma acute, depression, opportunistic infections, pneumonia, hypertension, and lipid disorders, with the highest risk associated with skeletal conditions and infections.
Magnesium sulfate has both immediate bronchodilator effects and mild anti-inflammatory effects. The role of heliox - driven albuterol in the treatment of acute exacerbations continues to be a controversial topic.
Many limitations remain that complicate the understanding of the current literature. Despite these uncertainties, heliox — driven albuterol should be considered in both children and adults who exhibit severe life-threatening exacerbations and those who remain in the severe category after 1 hour of intensive conventional therapy [11,24].
Failure to respond to treatment necessitates hospitalization. Hydration in young infants and children may be essential as these patients are at accounting entries for stock option plans risk for dehydration due to poor oral intake and an increased respiratory rate. The patient should be monitored continuously with pulse oximetry and telemetry. Blood gases should be obtained until the patient is stable, asthma acute.
The patient should be treated with continuous nebulized albuterol or levalbuterol, with or without ipratropium bromide, and a corticosteroid, asthma acute, e. If the patient is not responding and is deteriorating a decision should be made to assist ventilation before the patient has a respiratory arrest.
Viral respiratory tract infections are more common in acute asthma exacerbation and therefore antibiotics should be reserved for patients who present with evidence of a co-existing bacterial infection, i. The EPR3 does not recommend the use of methylxanthines, mucolytics, sedation or chest physiotherapy for treatment in acute asthma [1, 11,25].
Patient education is important to ensure that the patient understands that asthma is mostly a chronic disease and necessitates the avoidance of allergens, prevention of infections, compliance with routine vaccinations, asthma acute, management of comorbid conditions and adherence to treatment regimens. The importance of taking an ICS on a asthma acute basis and limiting asthma acute use cannot be over emphasized.
