A 30-year-old male presents to the emergency department with a three-day history of worsening difficulty in breathing, which is not responding to his usual treatment. He reports a history of similar episodes in the past. On auscultation, rhonchi are heard in both lungs, and there is cyanosis of the hands, but no clubbing is noted. The patient is conscious, but he appears distressed. What is the first-line treatment you would administer?
A. IV furosemide
B. IV hydrocortisone
C. Inhalation of Ventolin
D. IV diazepam
E. IV aminophylline
Correct Answer: C. Inhalation of Ventolin
Explanation:
The clinical presentation of difficulty breathing, rhonchi on auscultation, and cyanosis (without clubbing) suggests an acute exacerbation of asthma or possibly chronic obstructive pulmonary disease (COPD), though asthma is more likely in a young patient with a history of similar episodes.
The first-line treatment in such a situation would involve bronchodilation to relieve the bronchospasm that is causing the difficulty in breathing. The most common and effective bronchodilator for acute management in asthma exacerbations is Ventolin (a short-acting beta-agonist, or SABA), which works by relaxing the smooth muscles of the airways and improving airflow.
Inhalation of Ventolin (Salbutamol) provides rapid relief of symptoms by dilating the bronchial muscles, thus improving ventilation and reducing wheezing and rhonchi. This should be given immediately to the patient via a nebulizer or metered-dose inhaler (MDI) to open up the airways and provide symptomatic relief.

Why Other Options Are Incorrect:
A. IV furosemide:
- Furosemide is a loop diuretic used for managing fluid overload conditions such as heart failure, pulmonary edema, or renal failure. However, the patient’s symptoms are more consistent with a respiratory issue, specifically an asthma exacerbation, and there is no evidence of fluid overload. Therefore, furosemide would not be appropriate in this scenario.
B. IV hydrocortisone:
- Hydrocortisone (a corticosteroid) can be used in the treatment of severe asthma exacerbations to reduce inflammation and improve long-term control. However, it is not the first-line treatment in this acute setting. The immediate concern is to open the airways with a bronchodilator (Ventolin), and steroids like hydrocortisone are typically given subsequently to reduce the inflammation over time. Therefore, hydrocortisone is not the first step in treatment.
D. IV diazepam:
- Diazepam is a benzodiazepine used to treat anxiety, seizures, or to relax muscle spasms. While it can be used in some cases of respiratory distress related to anxiety or panic attacks, it does not address the underlying bronchoconstriction in conditions like asthma. It is not a first-line treatment for acute airway obstruction or respiratory distress related to asthma.
E. IV aminophylline:
- Aminophylline is a theophylline derivative used for bronchodilation in some cases of asthma or COPD. It can be effective in certain situations but is not the first-line treatment due to its slower onset of action and potential for significant side effects such as arrhythmias and nausea. Ventolin (a beta-agonist) is more commonly used as the initial treatment due to its rapid onset and better safety profile in the acute setting.
Management of Acute Asthma Exacerbation:
- Initial Stabilization:
- Assess the severity of the patient’s symptoms using clinical signs and symptoms (e.g., respiratory rate, oxygen saturation, wheezing).
- Administer oxygen if necessary to maintain oxygen saturation > 90%.
- Bronchodilation (First-line treatment):
- Administer Ventolin (salbutamol), either by nebulizer or metered-dose inhaler (MDI) with a spacer.
- This bronchodilator helps to rapidly relieve bronchospasm and improves airflow by relaxing the smooth muscles in the airways.
- Systemic Corticosteroids (Secondary treatment):
- If the patient’s symptoms do not improve with bronchodilators, administer systemic steroids (e.g., IV hydrocortisone or oral prednisolone).
- Corticosteroids help reduce the inflammatory component of the asthma exacerbation and provide longer-term relief.
- Additional Bronchodilators (If needed):
- Aminophylline or other bronchodilators may be considered if the patient’s symptoms persist despite initial treatment with Ventolin and systemic steroids. However, this step is usually done after first-line therapies.
- Monitoring and Support:
- Continuous monitoring of vital signs, oxygen saturation, and peak flow rates is essential during treatment.
- Reassessment should be done frequently to ensure that the patient is responding to therapy.
- If there is no improvement after initial treatment, or if there are signs of severe asthma exacerbation (e.g., confusion, severe hypoxia), consider intubation or transfer to a higher level of care.
