Childhood asthma--office management
1K.E.M. Hospital, Parel, Bombay.
Insights
Childhood asthma management involves immediate intensive care for life-threatening attacks. Non-life-threatening asthma can be treated in-office with inhaled bronchodilators, followed by oral or inhaled medications and parent education for better control.
Area of Science:
- Pediatrics
- Pulmonology
- Allergy and Immunology
Background:
- Childhood asthma presents a significant challenge in primary care settings.
- Acute exacerbations require prompt and appropriate management to prevent severe outcomes.
Purpose of the Study:
- To outline a management strategy for acute childhood asthma attacks in an office setting.
- To provide guidance on differentiating and treating life-threatening versus non-life-threatening exacerbations.
- To detail the progression of pharmacological interventions and maintenance therapy.
Main Methods:
- Initial assessment to determine attack severity (life-threatening vs. non-life-threatening).
- Administration of inhaled short-acting beta-2 agonists (SABAs) as first-line treatment.
- Use of subcutaneous epinephrine or SABAs for severe bronchospasm or if inhalation is not feasible.
- Introduction of oral/parenteral corticosteroids and intravenous theophylline for inadequate responses.
- Grading of illness severity (Stage I-V) for initiating appropriate maintenance therapy.
- Emphasis on patient and parent education for improved compliance and environmental control.
Main Results:
- Successful management of non-life-threatening asthma attacks in an office setting is achievable.
- A stepwise approach using bronchodilators, corticosteroids, and theophylline effectively controls acute exacerbations.
- Tailored maintenance therapy based on illness severity (Stages I-V) improves long-term asthma control.
- Parent and patient education is crucial for enhancing treatment adherence and environmental management.
Conclusions:
- A structured approach to childhood asthma exacerbations in primary care can lead to effective outcomes.
- Timely and appropriate pharmacological interventions, combined with patient education, are key to managing childhood asthma.
- Severity-based maintenance therapy ensures optimal long-term control and reduces the risk of future exacerbations.
Abstract:
Childhood asthma is a major problem in office practice. For an acute life threatening attack (which is indicated by presence of severe distress, pulsus paradoxus, oxygen saturation less than 93%, cyanosis, peak expiratory flow rate of less than 50% of predicted) child should be directly admitted in intensive care unit. If it is a non life threatening attack the child can be managed in the office. Initially, the child should be given b2 agonists by inhalation route with either metered dose inhaler (MDI), MDI with spacer or nebuliser. It there is severe bronchospasm or inhalation therapy is not possible then epinephrine of b2 agonists may be given subcutaneously. The medications can be repeated 2-3 times. If response is adequate the child may be sent home on b2 agonist by oral or inhalation route at an interval of 406 hours. In case of inadequate response the child is started on oral or parenteral corticosteroids. Even after steroids if inadequate response the child is started on intravenous theophylline. Once the acute exacerbation is controlled the child is assessed for starting maintenance therapy. For this purpose his illness is graded from stage I to V depending on the severity. For stage I and II b2 agonists are prescribed as and when required. For stage III sodium cromoglycate by inhalation should be prescribed. For stage IV inhalation steroids in usual doses and for stage V inhalation steroids in higher doses are prescribed along with a minimum dose of oral steroids is added. For symptomatic control slow release theophylline or long acting b2 agonists may be added along with maintenance therapy as and when required. Apart from medications a proper education of parents and patients is necessary to improve the outcome of asthma by increasing the compliance and better control of environment.
