KEY POINTS

  1. Routine pulmonary function tests are not usually necessary for patients with chronic obstructive pulmonary disease. Elective surgery may need to be postponed for acute exacerbations.

  2. In patients with asthma, pretreatment with bronchodilators can mitigate the risks of bronchospasm in the perioperative period.

  3. Obstructive sleep apnea is associated with important systemic comorbidities, and patients should be encouraged to use continuous positive airway pressure (CPAP) whenever feasible.

  4. Smoking cessation should be attempted in any perioperative patient, even in the immediate preoperative period.

  5. Intraoperative mechanical ventilation should optimize both pressures and volumes to minimize the risk for additional lung injury in patients with preexisting pulmonary disease.

  6. Optimal postoperative analgesia, including thoracic epidural catheterization, may improve adjunct pulmonary markers.

  7. Pulmonary recruitment with early ambulation and incentive spirometry should be encouraged in the postoperative period.

INTRODUCTION

++

One of the most fundamental tasks of the anesthesiologist is to ensure normal, or at least best-case, function of the respiratory system throughout the entire perioperative period. In addition to a solid foundation in normal pulmonary physiology and mechanics, this necessitates a thorough understanding of common lung disease and optimization of pulmonary status throughout the perioperative care arc (pre-, intra-, and postoperatively).1 Although perioperative major adverse cardiac events and complications receive prominent attention, postoperative pulmonary complications (PPCs) are more common and costly (see Table 10-1 for a definition of PPCs).1-3 Accordingly, this chapter has three objectives: (1) discuss the preoperative pathophysiology, evaluation, and optimization of patients with common lung diseases and risk factors for PPCs; (2) outline intraoperative management strategies to improve pulmonary status and decrease the risk of PPCs; and (3) describe the prevention and treatment of PPCs in the postoperative period.
