What is a common adjunct bronchodilator used with albuterol in ICEMA standing orders?

• A. Albuterol
• B. Epinephrine
• C. Ipratropium bromide
• D. Theophylline

Answer: (C)

Using two bronchodilators that work by different mechanisms provides better relief in bronchospasm. Albuterol is a fast-acting beta-2 agonist that relaxes airway smooth muscle to widen the airways. Ipratropium bromide is an anticholinergic that blocks acetylcholine’s effect on the airways, reducing constriction and secretions. When given together, they produce additive bronchodilation and help improve airflow more effectively than either alone, which is why ipratropium bromide is the common adjunct in ICEMA standing orders with albuterol.

Epinephrine can be used in severe, life-threatening cases but is not a routine adjunct in standard standing orders due to broader systemic effects. Theophylline is largely obsolete in EMS because of narrow therapeutic windows and interactions, making it unlikely as a standard adjunct. Albuterol remains the primary bronchodilator, with ipratropium added for enhanced effect.
