- Bronchospasm is caused when the muscles inbronchi(air tubes in the lungs) contract, causing narrowing of the air tubes inside the lungs. When this happens there can be coughing, wheezing, and difficulty breathing. The narrowing comes from swelling and muscle spasm inside the air tubes
- Inflammation or irritation of the airways is the cause of bronchospasm. This is triggered by allergies, viral lung infections, or irritants in the air. Viral infections however are believed to be the most common cause for bronchospasm. If allergens are causing bronchospasms, your child can wheeze immediately when exposed to allergens or many hours later
- Common triggers for an attack include:
- Allergies(animals, pollen, food, and molds) can trigger attacks.
- Infection(usually viral) commonly triggers attacks. Antibiotics are not helpful for viral infections. They usually do not help with reactive airway disease or asthmatic attacks.
- Exercisecan trigger a reactive airway disease or asthma attack. Proper pre-exercise medications allow most children to participate in sports.
- Irritants(pollution, cigarette smoke, strong odors, aerosol sprays, paint fumes, etc.) all may trigger bronchospasm.
- SMOKING SHOULD NO BE ALLOWED. MORE THAN PERSONAL EFFECTS, IT IS TRIGGER AND CAN PROVIDE IRRITATION FOR HOURS(TERTIARY SMOKING)
- Weather changes. There is not one best climate for children with asthma. Winds increase molds and pollens in the air. Rain refreshes the air by washing irritants out. Cold air may cause inflammation.
- Stress and emotional upset. Emotional problems do not cause bronchospasm or asthma but can trigger an attack. Anxiety, frustration, and anger may produce attacks. These emotions may also be produced by attacks.
SYMPTOMS
Wheezing and excessive nighttime coughing are common signs of bronchospasm, reactive airway disease and asthma. Frequent or severe coughing with a simple cold is often a sign that bronchospasms may be asthma. Chest tightness and shortness of breath are other symptoms. These can lead to irritability in a younger child. Early hidden asthma may go unnoticed for long periods of time. This is especially true if your child’s caregiver can not detect wheezing with a stethoscope.Pulmonary(lung) function studies may help withdiagnosis(learning the cause) in these cases
-
- Control your home environment in the following ways:
- Change your heating/air conditioning filter at least once a month.
- Use high quality air filters where you can, such as HEPA filters.
- Limit your use of fire places and wood stoves.
DONT SMOKE
-
- avoid pets- dander /urine could trigger asthma
- mopp your floor/sun your rooms
- change bedsheets and pillow covers as frequently you can- they are great reservoir of house dust mite
- wood as fuel adds smoke to your whatever be type of chimney you have
- asthma changes in airway
- Get rid of pests (cockroaches) and their droppings.
- If you see mold on a plant, throw it away.
- Clean your floors and dust every week. Use unscented cleaning products. Vacuum when the child is not home. Use a vacuum cleaner with a HEPA filter if possible.
- If you are remodeling, change your floors to wood or vinyl.
- Use allergy-proof pillows, mattress covers, and box spring covers.
- Wash bed sheets and blankets every week in hot water and dry in a dryer.
- Use a blanket that is made of polyester or cotton with a tight nap.
- Limit stuffed animals to one or two and wash them monthly with hot water and dry in a dryer.
- Clean bathrooms and kitchens with bleach and repaint with mold-resistant paint. Keep child with asthma out of the room while cleaning.
- Wash hands frequently.
Always have a plan prepared for seeking medical attention. This should include calling your child’s caregiver, access to local emergency care, and calling 911 (in the U.S.) in case of a severe attack
- ASTHMA is best treated withed inhaled broncho dilators and steroid( acute rescue -oral and long term control-inhaled corticosteroid
- Inhalers are best because small quantity of drugs(microgram) is delivered directly to lungs, WHERE THE BASIC PROBLEM OF ASTHMA EXIST
- if you take tablet of 2mg bronchodilator( 2,000 microgram) once,same effect can be achieved with on puff(100 microgram) of bronchodilator inhalers.When tablet if fully absorbed side effects are more .In inhalers only 10% of the drug is absorbed so naturally side effect is less. So the effective dose from an inhaler is 10 microgram.When compared steroid tablet of 10 mg(=10,000 microgram) and inhaler of 100 ugm( 10 %=10 microgram) ,you have to use 1000 times more of oral steroid dose to get same effect with inhalers. so when you are using tablet you are pumping very high quantity to get desired effect.
- IF YOU ARE NOT USING INHALERS FOR TRETMENT OF ASTHMA, THEN THERE IS SOMETHING SERIOUSLY WRONG WITH YOU,REST OF THE WORLD IS NOT FOLLOWING YOU
