What is status asthmaticus?
Status asthmaticus is a long-lasting and severe asthma episode that does not respond to standard treatment. It occurs when asthma symptoms - difficulty breathing, wheezing, and coughing - fail to improve with emergency medication treatment. Status asthmaticus is caused by severe bronchospasm, in which the smooth muscles of the bronchi suddenly contract and narrow the airways. Asthma attacks can be triggered by allergens, such as pollen, smoke, and animal dander,
as well as by physical exertion and cold air. Status asthmaticus is a severe, prolonged, immobilising attack of asthma that is unresponsive to normal bronchodilator treatment. The symptoms of status asthmaticus are extreme difficulty with breathing, which causes restlessness and anxiety. Although coughing and wheezing are common symptoms of asthma, a child with status asthmaticus may not cough or wheeze because there is not enough airflow. Advanced symptoms include little or no breath sounds, inability to speak, bluish tinge to the skin (cyanosis), and heavy sweating. Status asthmaticus can lead to unconsciousness and cardiopulmonary arrest, which can be fatal.
Status asthmaticus is an emergency situation that can lead to death. Treatment of this condition may be started at home but hospital treatment is indicated. Patient management is based upon administering large doses of corticosteroid drugs and bronchodilators and ensuring that the patient is receiving adequate oxygenation until the attack is completed. A person with this condition needs to immediately see a health professional or go to a hospital's emergency department. To treat status asthmaticus, the patient is given supplemental oxygen to increase blood oxygen levels. He or she will also be treated with an inhaled or intravenous bronchodilator to open the airways. Other common treatements include corticosteroids, to reduce inflammation, and anticholinergics, to block smooth muscle contraction and the production of excess mucus. The patient’s heart rate, blood pressure, fluid levels, and blood oxygen, pH, and carbon dioxide levels are monitored carefully. Intravenous fluids are given if the child is dehydrated. A patients with severe respiratory distress, extreme lethargy, altered consciousness, elevated carbon dioxide levels, or high blood acidity (acidosis) needs to be hospitalized in a pediatric intensive care unit (PICU).
More information on asthma
What is asthma? - Asthma is a chronic inflammatory respiratory disease characterized by periodic attacks of wheezing, shortness of breath, and a tight feeling in the chest.
What types of asthma are there? - Types of asthma include child-onset asthma, adult-onset asthma, exercise-induced asthma, cough-variant asthma, occupational asthma, nocturnal asthma.
What's bronchial asthma? - Bronchial asthma is a disease of the lungs in which an obstructive ventilation disturbance of the respiratory passages evokes a feeling of shortness of breath.
What is exercise-induced asthma? - Exercise-induced asthma is a form of asthma that some people have during or after physical activity. Exercise-induced asthma is common.
What is adult-onset asthma? - Adult onset asthma generally is the onset of asthma for the first time in someone of middle age or older. Adult-onset asthma develops after age 20.
What is status asthmaticus? - Status asthmaticus is a severe asthma episode that does not respond to standard treatment. Status asthmaticus is caused by severe bronchospasm.
What causes asthma? - Asthma is caused by inhaling an allergen that sets off the chain of biochemical and tissue changes leading to airway inflammation, bronchoconstriction, and wheezing.
What're the asthma triggers? - Many risk factors have been linked to triggering asthma attacks. There are two basic types of asthma triggers, allergic triggers, non-allergic triggers.
Asthma and allergy - Asthma attacks (worsening of asthma symptoms) can be triggered by allergies. Allergy is the leading cause of asthma.
What is an asthma attack? - An asthma attack occurs when the small and medium-sized airways become inflamed and constricted after being exposed to a trigger.
Asthma in children - Asthma is the most common chronic condition of childhood. Asthma symptoms can interfere with many school activities for children.
Asthma and pregnancy - During pregnancy, asthma or asthma episodes will become worse for an estimated one-third of pregnant women, particularly women who have severe asthma.
Asthma in adults and older people - Identifying asthma in the elderly can be difficult because asthma symptoms can be confused with symptoms of heart or lung diseases.
What're the complications of asthma? - Uncontrolled asthma in pregnant women puts them at higher risk for complications that can include early labor, hypertension, gestational diabetes.
What are the symptoms of asthma? - The symptoms of asthma include labored breathing, constriction of the chest, coughing and gasping usually brought on by allergies.
What're the warning signs of asthma? - Most people with asthma have warning signs before symptoms appear. There are many warning signs of an asthma episode.
How is asthma diagnosed? - The diagnosis of asthma is made on the basis of typical symptoms and signs. Positive allergy tests support a diagnosis of asthma.
What're the treatments for asthma? - Treatment of asthma is aimed at avoiding known allergens and respiratory irritants and controlling symptoms and airway inflammation through medication.
What quick relief (rescue) medications cure asthma? - Short-acting beta-agonists are the most commonly used asthma rescue medications. Anticholinergics are another class of asthma drugs.
Long-term asthma control medications - Combinations of steroids and other medications are effective for both treating and preventing asthma attacks in patients with moderate to severe asthma.
What're asthma inhalers? - Most asthma drugs are inhaled using special devices or nebulizers. Two common types include dry powder asthma inhalers and metered-dose asthma inhalers.
What're asthma nebulizers? - Asthma nebulizers can be used with all classes of inhaled medications but are most commonly used with short-acting beta2 agonists and ipratropium bromide.
How to control acute asthma attacks? - Acute asthma is an acute exacerbation of wheezing, unresponsive to usually effective therapy and necessitating care in an emergency room or hospital ward.
How to manage chronic asthma symptoms? - The aims of management are to recognize asthma, to abolish symptoms, to restore normal or best possible long term airway function.
What asthma relievers are available? - Asthma reliever is a drug that provides relief from asthma symptoms and is the most commonly used asthma medication.
What asthma preventers are available? - Asthma preventers are to be used twice a day regardless of whether your child has symptoms of asthma.
What's the treatment for childhood asthma? - The goals of asthma therapy are to prevent child from having chronic and troublesome symptoms, to maintain child's lung function.
What's the treatment for asthma in the elderly? - Diagnosis and treatment of asthma can be more complicated in people age 65 and older than in those who are younger.
What can be done to prevent asthma? - Avoiding known allergens and respiratory irritants can reduce asthma symptoms. People with asthma should minimize risk for respiratory tract infections.
