THE diagnosis of pulmonary emphysema and chronic bronchitis appears as an associated condition in an increasing number of patients admitted to the pavilion surgical services at The New York Hospital-Cornell Medical Center. Like diabetes mellitus, arteriosclerotic cardiovascular disease and obesity, pulmonary emphysema and chronic bronchitis are known to increase the risk of operation by complicating the postoperative period.1 In the past decade there has been a steady rise in the incidence of this chronic lung disease as reported in national statistics,2 and since this trend is expected to continue especially in large industrial and urban areas, the study of the surgical patient with this associated condition is of interest.
