What is the primary aim of asthma management?

The main goal of asthma management is to help patients avoid triggers that initiate attacks and mitigate the effects of those triggers. When emergency medical services (EMS) are called, it indicates these goals have not been achieved.

What is the primary medication used for asthma attacks?

When an asthma attack occurs, the initial line of treatment is inhaled beta2-specific drugs, such as Albuterol. These drugs target the beta2 receptor in the airways, helping to relax the muscles and open the airways.

Describe the benefits of Albuterol in treating asthma attacks.

Albuterol is a common inhaled bronchodilator used to treat asthma attacks. It targets the beta2 receptor in the airways, relaxing muscles and opening up the airways. It's preferred over older beta2 agonists that had unwanted side effects on other receptors in the body.

How does Levalbuterol compare to Albuterol in asthma treatment?

Levalbuterol is a newer version of Albuterol, known for having fewer adverse effects. Both are effective in treating acute asthma exacerbations. The development of these drugs showcases the progression from older, less specific beta2 agonists to newer, more targeted medications.

What makes third-generation beta2 agonists more effective than previous versions?

Third-generation beta2 agonists are the most targeted type of inhaled bronchodilators. They primarily target the beta2 receptor, minimizing systemic side effects. This allows for multiple and continuous treatments for moderate to severe asthma exacerbations.

How do inhaled bronchodilators work to treat asthma attacks?

Inhaled bronchodilators, such as Albuterol and Levalbuterol, help to relax the muscles in the airways, opening them up and improving breathing. They are often the first-line treatment for asthma attacks.

What is the next step in asthma treatment when inhaled medications are ineffective?

When inhaled bronchodilators are ineffective in managing asthma attacks, intravenous (IV) medications are administered. These medications aim to reduce bronchospasm and inflammation, providing more targeted relief for severe exacerbations.

Study Notes

Drugs Used to Treat Respiratory Emergencies

  • Respiratory distress is a common presentation in prehospital settings, affecting people of all ages and demographics.
  • While underlying causes of respiratory distress vary, reversible bronchial constriction (bronchospasm) is a frequent target of prehospital treatment.
  • Advanced life support (ALS) interventions, including respiratory medications, considerably reduce mortality in respiratory distress cases.

Oxygen

  • Oxygen is the most frequently used medication in prehospital settings.
  • Oxygen use has associated risks and benefits.
  • Daily oxygen use by prehospital providers often lacks consideration of its pharmacological properties.
  • Current guidelines suggest titrating oxygen to prescribed saturation levels rather than applying it indiscriminately, particularly in neonatal resuscitation, COPD exacerbations, and acute coronary syndromes.
  • Continuous oxygen needs may require a transtracheal catheter for some patients with COPD.
  • Transtracheal catheters, like nasal cannulas, are used for long-term oxygen therapy in chronic lung diseases.
  • Nasal cannulas might cause discomfort at night, so a transtracheal catheter would be used in those cases

Bronchodilators

  • Asthma and COPD can lead to respiratory distress due to functional narrowing of the conducting airways.
  • Symptoms can feel like breathing through a straw.
  • Bronchospasm, narrowing of the bronchial smooth muscle, decreases airway diameter.
  • Airway inflammation and edema also cause airway narrowing.
  • Increased secretions within the airways compound respiratory distress in these conditions.
  • Bronchodilators can be selective or nonselective, targeting different receptors.
  • Selective agents generally focus on bronchial smooth muscle, effectively improving condition with minimal side effects.
  • Selective beta2 agonists (like albuterol) relax bronchial smooth muscle without increasing heart rate or blood pressure.
  • Beta2 agonists should be used cautiously for those with heart conditions and the electrocardiogram should be monitored during and after treatment.
  • Nonselective agents act on alpha, beta1, and beta2 adrenergic receptors. Alpha receptor stimulation increases blood pressure, beta1 acts on the heart increasing rate and contractility, and beta2 relaxes bronchial smooth muscle, allowing for bronchodilation.
  • Racemic epinephrine is an example of a nonselective bronchodilator.

Management of Asthma

  • Avoiding triggers, whenever possible, is a key management strategy for asthma.
  • In prehospital settings, initial interventions focus on reversing acute bronchospasm.
  • Inhaled beta2-specific drugs are the first-line treatment for asthma.
  • Intravenous medications are used if inhaled bronchodilators are ineffective.
  • Albuterol (Proventil, Ventolin) is a common inhaled bronchodilator targeting beta2 receptors.
  • Levalbuterol (Xopenex) is a newer form of albuterol with supposedly fewer adverse effects.
  • Ipratropium bromide (Atrovent) is an anticholinergic that targets bronchospasm in severe cases or if beta2 agonists are ineffective.
  • Combination products like Albuterol/ipratropium (Combivent) deliver both medications in a single preparation.

Second-Line Therapy for Acute Asthma Exacerbation

  • Lung conditions causing obstruction, like COPD, present a clinical picture of gasping for breath and use of accessory muscles of respiration.
  • While bronchodilators treat symptoms, they don't address the underlying cause.
  • Prolonged transport times suggest including corticosteroids (methylprednisolone, dexamethasone) to manage the inflammatory processes related to exacerbation.
  • PEFR (peak expiratory flow rate) can guide therapeutic interventions and determine exacerbation severity/response to therapy.
  • If PEFR is less than 50% of predicted, corticosteroids are administered after ipratropium.
  • Corticosteroids should be considered when PEFR doesn't improve at least 10% post-bronchodilator therapy or is less than 70% after 1 hour.
  • Aminophylline and other methylxanthines, once frequently used, are less commonly recommended for acute respiratory distress scenarios.
  • Magnesium sulfate can help decrease bronchospasm in some patients who don't respond well to beta2 agonists.
  • For young patients, epinephrine was once the preferred treatment, but its short-term and undesirable effects make it a less popular choice.
  • Rebound bronchospasm can occur with epinephrine administration, so it should be used with caution
  • Epinephrine is still considered if an anaphylactic reaction is suspected.

COPD Management

  • In COPD exacerbations, treatment initially focuses on oxygenation and ventilation.
  • Careful oxygen administration is key, as an overdose removes the hypoxic respiratory drive that helps patients breath.
  • Consider a pulse oximetry level in the low 90s as adequate.
  • Similar to asthma management, bronchodilators and corticosteroids can be used to manage COPD exacerbations.

Overview of Asthma

  • Acute asthma attacks affect all ages, resulting from reactions in the body (intrinsic) or from outside factors (extrinsic).
  • Asthma triggers range from exertion or stress (intrinsic) to animal dander, dust, pollen, and cleaning products (extrinsic).
