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).
