Morbidity and Mortality After Thoracoscopic Pneumonoplasty

Department of Anesthesiology, Chapman Medical Center, Orange, California

Accepted for publication March 4, 1996.

Background. Both video-assisted thoracic surgery and open pneumonoplasty procedures have been used to achieve lung reduction in emphysema patients.

Methods. The surgical and hospital course of 339 patients with a mean forced expiratory volume in 1 second of 750 mL and a mean ratio of forced expiratory volume in 1 second to forced vital capacity of 35% undergoing video-assisted thoracic surgical laser pneumonoplasty was analyzed.

Results. The incidence of myocardial infarctions was 0.9% and the hospital mortality rate was 4.1%.

Conclusions. Factors leading to increased morbidity and mortality were advanced age (65 years and greater, especially greater than 75 years), sex (men greater than women), carbon dioxide retention in the resting state (especially an arterial carbon dioxide tension greater than 55 mm Hg), forced expiratory volume in 1 second less than 700 mL for men and 500 mL for women, maximum voluntary ventilation less than 25% predicted, and a ratio of residual volume/total lung capacity greater than 60%.
