Treatment Of Acute Bronchial Asthma

Patients At Risk For Severe Asthma Exacerbations

Careful consideration should be carried out in patients with risk factors for severe asthma exacerbations. Patients with exacerbations that led to endotracheal intubation, previous admissions to the ICU, a history of multiple hospitalizations in the past year or multiple emergency department visits in the past month, the need of chronic oral corticosteroids use, poor access to health care, and frequent use of rescue inhalers are considered to have increased risk of severe asthma exacerbations and death. Patients with asthma and with these characteristics should be evaluated promptly and treated expeditiously. In addition, a minority of patients with asthma may experience a significant decline in lung function without a change in symptoms. These under-perceivers are at higher risk for near-fatal exacerbations. This article focuses on the approach to manage exacerbations of asthma.

Patients having an asthma exacerbation are instructed to self-administer 2 to 4 puffs of inhaled albuterol or a similar short-acting beta agonist up to 3 times spaced 20 minutes apart for an acute exacerbation and to measure peak expiratory flow if possible. When these short-acting rescue drugs are effective , the acute exacerbation may be managed in the outpatient setting. Patients who do not respond, have severe symptoms, or have a PEF persistently & lt 80% should follow a treatment management program outlined by the physician or should go to the emergency department .

Allergies And Bronchial Asthma

Allergies are a major trigger of bronchial asthma. Inhaling certain substances called allergens can trigger an allergic reaction, causing your airways to become irritated, inflamed, and swollen.

Swelling and inflammation narrow the opening that air passes through, making it more difficult to breathe. Wheezing sounds and coughing are common symptoms that can develop with an allergic asthma attack.

Many allergens can lead to an asthma attack. Food allergies and allergic skin reactions are linked to a higher risk of asthma.

What Causes Asthmatic Bronchitis

There are many triggers that may initiate the release of inflammatory substances. Common asthmatic bronchitis triggers include:

• Chest tightness
• Excess mucus production

You might wonder, is asthmatic bronchitis contagious? Bronchitis itself can be caused by a virus or bacteria, which are contagious. However, chronic asthmatic bronchitis typically is not contagious.

Management And Treatment Of Acute Asthma

While chronic asthma has no cure, it can be controlled. With proper management and treatment, the occurrence of acute asthma attacks can be minimized.

An asthma treatment plan will be two-pronged: control of chronic asthma and treatment of acute asthma symptoms. Together, these two paths will help minimize the chances of attacks and make them easier to deal with when they do occur.

How Do Healthcare Providers Diagnose Asthma

Your healthcare provider will review your medical history, including information about your parents and siblings. Your provider will also ask you about your symptoms. Your provider will need to know any history of allergies, eczema and other lung diseases.

Your provider may order spirometry. This test measures airflow through your lungs and is used to diagnose and monitor your progress with treatment. Your healthcare provider may order a chest X-ray, blood test or skin test.

Clenbuterol For Treatment Of Acute Bronchial Asthma

Clenbuterol is a steroid-like drug used as a bronchodilator and decongestant by those suffering from breathing disorders. It relaxes the smooth muscle tissue in the airways to allow for freer breathing. Clenbuterol relaxes and widens the smooth muscles in the airways to improve breathing. It also increases the volume of oxygen in the blood.

Enhancing Healthcare Team Outcomes

In many countries, including the US, asthma kills one out of every 100,000 persons. The worse the lung function, the higher the mortality. In addition, mortality has also been linked to poor management and lack of medication compliance, especially in young people. Other factors that increase the risk of death include smoking and use of illicit drugs.

Asthma also results in millions of school and workdays lost. In the US alone, close to 2 million asthmatics seek regular care in the emergency department, which also increases the costs of healthcare.

Even though asthma is a reversible disorder, poor lifestyle and lack of management can lead to airway remodeling that leads to chronic symptoms, which are disabling.

The disorder has no cure, and thus life long monitoring is necessary. For best outcomes, an interprofessional approach is recommended.

Evidence-based Medicine

Many evidence-based asthma plans are available for the management of asthma and should be handed out to patients. Finally, nurses also play a vital role in school-based asthma education programs that can help improve self-esteem, knowledge, and self-management behaviors.

What Are The Signs And Symptoms Of Asthma

People with asthma usually have obvious symptoms. These signs and symptoms resemble many respiratory infections:

• Chest tightness, pain or pressure.

With asthma, you may not have all of these symptoms with every flare. You can have different symptoms and signs at different times with chronic asthma. Also, symptoms can change between asthma attacks.

What Asthma Treatment Options Are There

You have options to help manage your asthma. Your healthcare provider may prescribe medications to control symptoms. These include:

• Bronchodilators: These medicines relax the muscles around your airways. The relaxed muscles let the airways move air. They also let mucus move more easily through the airways. These medicines relieve your symptoms when they happen and are used for intermittent and chronic asthma.
• Anti-inflammatory medicines: These medicines reduce swelling and mucus production in your airways. They make it easier for air to enter and exit your lungs. Your healthcare provider may prescribe them to take every day to control or prevent your symptoms of chronic asthma.
• Biologic therapies for asthma: These are used for severe asthma when symptoms persist despite proper inhaler therapy.

You can take asthma medicines in several different ways. You may breathe in the medicines using a metered-dose inhaler, nebulizer or another type of asthma inhaler. Your healthcare provider may prescribe oral medications that you swallow.

Working On A Manuscript

Advances in the knowledge of clinical pharmacology and pulmonary physiology have significantly improved the management of asthma in children and adolescents. However, asthma prevalence, morbidity and mortality continue to increase in most countries .

Fig. 1

In the US, children with asthma incur an average yearly healthcare expenditure of $1128 ± $5310 compared with $468 ± $2960 for children without asthma. The purpose of this review is to examine the multiple alternatives available to treat the hospitalised child with acute severe asthma, and approaches to reduce the medical, economic and emotional burdens of this condition by the immediate use of aggressive and reliable pharmacological treatments.

Prior to a discussion of drug therapies, it is necessary to understand the indications for hospitalisation, intensive care unit admission, and the institution of mechanical ventilation so as to triage the asthmatic child to an appropriate treatment facility .

When To Visit A Doctor

Any unexplained or severe difficulty in breathing could be a potentially serious issue. Weve discussed a number of conditions that can result in such difficulties, and consulting with a doctor as soon as possible after it happens will help determine the underlying cause.

If youve already been diagnosed with asthma and have an attack that does not improve with your rescue inhaler, see a doctor immediately. If you notice your symptoms worsening, make an appointment as soon as possible.

Definition Epidemiology And Background

Asthma is a common, chronic inflammatory disorder of the airways characterized by paroxysmal or persistent symptoms and is associated with airflow limitation and airway hyper-responsiveness . Canadian experts have proposed that asthma can be diagnosed in children as early as 1 year of age, if presenting with frequent asthma-like symptoms or recurrent exacerbations reversible with salbutamol with no other alternative diagnosis . Asthma is the most common chronic disease in young people. The general prevalence of asthma in Canada has been estimated at 10%, but is higher in children and youth, including their Indigenous peers -. Asthma exacerbations are a frequent cause of emergency department visits and hospitalizations in children , and asthma is the leading cause of absenteeism from school . Preschool age children with asthma represent more than 50% of consultations in the ED . In one Alberta study, nearly 10% of paediatric ED visits resulted in admission, with one death for every 25,000 ED visits .

Many health care centres, along with national and international associations, have developed practice guidelines for the assessment and management of acute asthma exacerbations -. This statement specifically addresses the management of acute asthma exacerbations in paediatric patients with a known diagnosis of asthma, including preschoolers whose pattern of symptoms suggests likelihood for asthma or suspected asthma .

Acute Asthma: Causes Symptoms Diagnosis And Treatment

Asthma is a condition that results in the swelling and narrowing of the airways in the lungs. When you have an asthma attack, you will have difficulty breathing, chest tightness, and coughing.

Asthma can be an acute condition or a chronic one. This post will discuss the former, telling you everything you need to know about what causes acute asthma, how it is diagnosed, and what you and your doctor can do about it.

Have you considered clinical trials for Asthma?

We make it easy for you to participate in a clinical trial for Asthma, and get access to the latest treatments not yet widely available – and be a part of finding a cure.

Causes And Types Of Asthma

An asthma diagnosis means you have chronic swelling and inflammation in the bronchioles. Also referred to as wheezing or bronchial asthma, this condition can run in families or be triggered by allergies and irritants.

There are different types of asthma, which are classified by the cause of the condition or what triggers symptoms.

Can Acute Asthma Be Prevented

With proper care, you can learn the triggers that cause your acute asthma attacks and try to avoid them.

Because it might not always be possible to avoid the triggers, your doctor will likely provide you with a rescue inhaler that can help restore you to normal breathing should you feel an asthma attack coming on.

What Should I Do If I Have A Severe Asthma Attack

If you have a severe asthma attack, you need to get immediate medical care.

The first thing you should do is use your rescue inhaler. A rescue inhaler uses fast-acting medicines to open up your airways. Its different than a maintenance inhaler, which you use every day. You should use the rescue inhaler when symptoms are bothering you and you can use it more frequently if your flare is severe.

If your rescue inhaler doesnt help or you dont have it with you, go to the emergency department if you have:

• Anxiety or panic.
• Bluish fingernails, bluish lips or gray or whitish lips or gums .
• Chest pain or pressure.
• Very quick or rapid breathing.

Management Of Status Asthmaticus In The Icu

Patients admitted to the ICU include individuals who require ventilator support or those with severe asthma for whom therapy failed. Most often they have refractory hypercapnia, persisting or worsening hypoxemia, deteriorating PEF/FEV1, drowsiness, confusion, or impending signs of respiratory arrest. Elective intubation by an experienced clinician is always recommended as soon as signs of deterioration are present. Intubation and mechanical ventilation may lead to hypotension and barotrauma secondary to high positive intrathoracic pressures. Care must be taken to assure that intravascular volume is adequate before intubation, and a bolus of intravenous normal saline solution is often recommended before initiation of mechanical ventilation.

Although there are no studies that determined the optimal mode of mechanical ventilation, it seems prudent to use the mode with which one is most familiar. Most researchers have recommended an initial minute ventilation of 90130 mL/kg ideal body weight , with further adjustments based on pH and the plateau airway pressure. Based on studies by Tuxen and Lane and Peters et al, we usually use a tidal volume of 89 mL/kg with a breathing frequency of 1014 breaths/min, a flow of 100 L/s, and 0 PEEP. However, many institutions prefer to use tidal volumes of 68 mL/kg ideal body weight., We adjust the setting to maintain a plateau pressure of 30 cm H2O and judiciously adjust ventilator-applied PEEP based on its ability to lower intrinsic PEEP.

Therapy In The Emergency Department

Patients with mild-to-moderate asthma exacerbations may present to the emergency department to seek medical care. These patients should be treated as an out-patient when following the recommendation detailed above. Patients with severe or life-threatening asthma should always be managed in the emergency department. A focused, expedited history and physical examination should be carried out in all patients. It is critical to rule out other conditions that may mimic a severe asthma exacerbation, such as pneumonia, congestive heart failure, pneumothorax, and myocardial infarction. In patients with a severe exacerbation, careful attention should be placed on the level of consciousness, oxygen saturation, breathing frequency, resting pulse, and blood pressure, and on the use of accessory respiratory muscles. Patients with severe asthma may have a fast deterioration of their clinical presentation, so continuous monitoring of these patients is warranted. In the advanced stages of an asthma exacerbation, the pulmonary physical examination may reveal a silent chest, which may herald impending respiratory failure. Patients with severe asthma should also be monitored for potential complications of asthma, such as pneumothorax, pneumomediastinum, and anaphylaxis.

What Is The Difference Between Asthma And Bronchitis

Bronchitis is an infection in the bronchial tubes. Asthma is a long-term condition that causes the airways to narrow due to swelling in the muscle and membrane.

Bronchitis is a fixed inflammatory process that will always occur following infection. Asthma is a reversible inflammatory process that causes narrowing of the airway, as you can reverse it with certain inhaled medications.

Therefore, people with asthma have bronchial tubes that are more sensitive than those of people without asthma. This means that they are more likely to get infections in their bronchial tubes, or bronchitis.

Bronchitis, in turn, can also worsen the symptoms of asthma that a person may already experience.
