A clinical diagnosis of asthma should be suspected in the presence of recurrent/episodic wheezing, breathlessness, cough and or chest tightness with no alternative explanation for these symptoms. Asthma is a chronic inflammatory disorder of airways which causes hyper-responsiveness of airways and variable airway obstruction.

Role of Spirometry-

Wherever available, spirometry is recommended for all patients suspected of Asthma for confirmation.

Role of X-Ray Chest in Asthma-

Not recommended in routine in Asthma, but in some cases in whom some alternative diagnosis is suspected or complication of Asthma is suspected.

Allergy Testing in Asthma-

Tests for allergy status in Asthma-like total IgE, specific IgE to environmental allergens or Skin prick test is not routinely recommended. These tests can be done in specialized centers when specific triggers are suspected.

How to Assess Asthma Control?

Asthma control is classified as adequate or inadequate on the basis of day do-to-day symptoms, nighttime symptoms, limitation of activity and on pulmonary function like PEF and FEV!%.

Treatment of Choice in Acute Asthma Attack-

Role of Inhaled Steroids in Asthma-

Inhaled corticosteroid is controller medication of choice for the management of stable Asthma. Most of the benefit of ICS are obtained by minimal or moderate doses and an only minority of patients need higher doses..

Role of Long-Acting Beta2 Agonist (LABA) in Stable Asthma -

LABA should not be used as monotherapy. Addition of LABA to ICS is a preferred choice when ICS alone are not able to control symptoms.

Role of Leukotriene Receptor Agonist(LTRA) in Stable Asthma -

Monotherapy with LTRA is inferior to monotherapy with ICS. can be used as monotherapy in mild asthma, when the patient is unwilling to use ICS. LTRA can be added to LABA and ICS if asthma still remains on-controlled.

Role of Long-Acting Methylxanthines -

As monotherapy methylxanthine is inferior to ICS, so can be used as add on to ICS and LABA if asthma is uncontrolled.

Role of Short-Acting Beta2 Agonist (SABA) Salbutamol Solution -

Are effective as rescue medication. Oral Beta Agonist should not be used as rescue medication. These are:

The severity of Asthma Assessment -

Acute asthma may be nonsevere, severe and life-threatening. In severe asthma, the patient is agitated and unable to complete sentence and life-threatening asthma, the patient has altered mental status and orthopnea. Severe asthma should be treated in emergency/ ward and life-threatening, acute asthma needs admission to ICU.

Role of Oxygen in Asthma -

Oxygen should be used in the hypoxic patient.

Role of Bronchodilators in Acute Asthma -

Rapid-acting beta2 agonist (salbutamol) is the treatment of choice for an acute asthma attack. combination of ipratropium bromide with salbutamol produces better bronchodilation.

Role of Steroid in Acute Asthma -

Systemic Steroid should be used in all patients with severe acute asthma.

Role of Patient Education in Asthma -

Optimal self-management which involves a combination of patient education, self-monitoring, regular physician review, and self-management using a written asthma action plan is strongly recommended in the management of asthma.

Role of Pulmonary Rehabilitation in Asthma -

PR produces significant improvement in exercise capacity.

There is no role of vaccination and antibiotics in asthma.
