Stepwise treatment for relieving shortness of breath during an asthma attack, primarily including inhaled bronchodilators, systemic corticosteroids, and oxygen support.
Indication
- Sudden onset or worsening of shortness of breath, wheezing, or cough
- Shortness of breath that makes it difficult to speak
- Increased heart rate, decreased oxygen saturation (SpO2 < 94%)
- Significant decrease in peak flow rate (below 50% of personal best)
- Inadequate response to rescue medications in a known asthma patient
- Loss of asthma control triggered by infection, allergen, or exercise
Preparation
- The patient is calmed and placed in a sitting position
- Intravenous access is established and monitoring is started (heart rhythm, SpO2, blood pressure)
- Severity of respiratory distress is assessed (speech, oxygen, peak flow)
- Trigger factors (allergen, medication, infection) are reviewed
- Prior hospitalizations, intubations, and allergy history are recorded
How it's performed
- Oxygen support is initiated to target an oxygen saturation of 94-98%
- Short-acting beta-2 agonist (SABA) salbutamol is given by nebulization in 3 doses every 20 minutes
- Ipratropium bromide is added to SABA in severe attacks
- Systemic corticosteroid (oral prednisolone or IV methylprednisolone) is administered early
- Intravenous magnesium sulfate is considered if response is inadequate
- Non-invasive or invasive mechanical ventilation and intensive care are planned in cases of respiratory failure
Post-procedure
- Patients who respond can be discharged after 1-2 hours of observation
- A 5-7 day oral steroid course and maintenance inhaler plan are provided at discharge
- A pulmonology follow-up is recommended within 1-2 weeks
- Trigger avoidance, inhaler technique training, and peak flow monitoring are planned
- A written asthma action plan (steps to take during attacks) is provided
Risks
- Medication-related palpitations, tremor, and muscle cramps
- Elevation of blood sugar and blood pressure with high-dose steroids
- Respiratory failure and need for intubation in severe attacks unresponsive to treatment
- Rare mechanical complications such as pneumothorax
- Risk of recurrent attacks (especially if the underlying trigger is not addressed)
FAQ
When should I go to the emergency room during an attack?
Go to the emergency room immediately if you do not respond to the rescue inhaler, have difficulty speaking, notice bluish discoloration of lips or fingertips, or if your peak flow falls below half of your personal best.
Are steroid pills harmful?
A short 5-7 day oral steroid course during an asthma attack is effective and generally safe. Side effects increase with long-term use; duration is determined by the physician.
What should I pay attention to when using an inhaler?
Correct technique is critical. Using a spacer with metered-dose inhalers improves drug delivery to the lungs. Technique should be reviewed by a healthcare professional.
How can I prevent attacks?
Avoiding triggers (smoking, allergens, cold air, viral infections), using maintenance inhalers regularly, monitoring peak flow, and getting an annual flu shot reduce attack frequency.
