This chapter focuses on acute asthma and bronchospasm occurring in the perioperative period. Over 6% of the people in the United States have asthma, which is characterized by chronic inflammation, airway hyperresponsiveness, excessive mucus, and reversible airway obstruction. Due to generalized airway hyperreactivity, a history of asthma increases the risk of coughing, wheezing, bronchospasm, and oxygen desaturation. Although the incidence of bronchospasm associated with asthma is low, when it occurs it is often severe. A stepwise treatment algorithm is defined, which covers the use of first line agents such as inhaled beta-2 agonists and steroids, but also agents that are useful for refractory cases such as epinephrine, magnesium, and possibly ketamine.
