A Contemporary Approach to the Treatment of Perioperative Bronchospasm.

The incidence of asthma is increasing, and the ageing of the United States population is leading to an increase in the prevalence of patients living with chronic obstructive pulmonary disease. This has led to an increased need to manage bronchospasm in the perioperative period. Very effective methods to treat bronchospasm like intravenous dexmedetomidine, lidocaine, magnesium, ketamine and steroids as well as inhalational sevoflurane are available but are currently underused. Inhaled beta-2 agonists like albuterol are instead often relied upon as the sole therapeutic agent - often with limited response. Just like with pain management, the successful treatment of perioperative bronchospasm requires a multimodal approach. The diagnosis of intraoperative bronchospasm must be rapid, and the treatment must be effective to prevent the dreaded "dynamic hyperinflation syndrome". This article reviews the diagnosis of bronchospasm and the contemporary treatment methods that should be employed to prevent bronchospasm-related morbidity and mortality during the perioperative period.
