Office-Based Sedation/General Anesthesia for COPD Patients, Part II
The safe treatment of patients with chronic obstructive pulmonary disease (COPD) in dental office office-based settings can be quite complex without a current understanding of the etiology, course, severity, and current treatment modalities of the disease. The additional concerns of providing sedation and/or general anesthesia to patients with COPD in settings outside of a hospital demand thorough investigation of individual patient presentation and realistic development of planned treatment that patients suffering from this respiratory condition can tolerate. Along with other co-morbidities, such as advanced age and potential significant cardiovascular compromise, the dental practitioner providing sedation or general anesthesia must tailor any treatment plan to address multiple organ systems and mitigate risks of precipitating acute respiratory failure from inadequate pain and/or anxiety control. Part I of this article covered the epidemiology, etiology, and pathophysiology of COPD. Patient considerations in the preoperative period were also reviewed. Part II will cover which patients are acceptable for sedation/general anesthesia in the dental office-based setting as well as sedation/general anesthesia techniques that may be considered. Postoperative care will also be reviewed.

Effect of minute ventilation during oxygen-induced hypercapnia. During 15 minutes of high oxygen administration, which recovers substantially, is seen in patients with acute exacerbation of chronic obstructive pulmonary disease. However, the oxygen-induced hypercapnia does not recover. CO2, carbon dioxide; VE, minute ventilation.

Dynamic hyperinflation in patients with chronic obstructive pulmonary disease (COPD). Dynamic hyperinflation can be aggravated by artificial ventilation during general anesthesia. FRC, functional residual capacity.
