title: [Lung function influenced the prognosis of cardiac surgery in patients with chronic obstructive pulmonary disease].
abstract: Objective:To investigate the value of lung function for the prognosis of cardiac surgery in patients with chronic obstructive pulmonary disease(COPD).Methods:A retrospective analysis was conducted on the hospitalized patients with coronary heart disease or valvular heart disease in Beijing Anzhen hospital during Janury 2013 to December 2015. The relationship between lung function and extubation time, time of staying in ICU, second time tracheal incubation, tracheotomy and mortality rate were analyzed.Results:There were 355 patients without surgery in a total 1 729 of patients, of which 65 (18.31%)suffered from severe pulmonary dysfunction. There were 242 patients with obstructive ventilation dysfunction, 75 with mild, 127 with moderate, and 40 with severe and very severe obstructive ventilation dysfunction. There were significant differences in the rates of planned extubation and late extubation between patients with normal lung function (81.6% and 10.7%) and those with abnormal lung function(74.4% and 12.8%). In patients with different GOLD classification (Ⅰ, Ⅱ, and Ⅲ-Ⅳ), there were significant differences in the rates of early extubation 14.7%, 14.2% and 5%, planned extubation (80%, 74% and 65%) and late extubation (5.3%, 11.8% and 30%). By comparison with patients without COPD, the extubation time of COPD patients increased by 20.3%, the time of staying in ICU prolonged by 14.2%, and the mortality rate increased to 180%(P<0.05). However, there was no significant difference in the rate of second time tracheal incubation or tracheotomy.Conclusion:There was a close relationship between GOLD classification and prognosis of cardiac surgery patients with COPD. Cardiac surgery needs to be cautious because of increase in incidence of postoperative adverse events in patients with severe pulmonary dysfunction.
