Objective: With the arrival of China's aging society and the improvement of people's living standards, the incidence of atherosclerotic coronary heart disease (CAHD) increased year by year, coronary artery bypass graft surgery (CABG) coronary heart disease treatment has become the most one of the effective methods. The CABG postoperative pulmonary complications serious impact on the patient's postoperative recovery and surgical treatment. How to reduce the incidence of postoperative pulmonary complications, coronary heart surgical treatment has become a hot topic. In this paper, the analysis of the CABG postoperative pulmonary complications related factors, and be able to provide a theoretical basis for clinical treatment and prevention of the occurrence of pulmonary complications, and reduce the incidence of pulmonary complications after CABG. Methods: Cardiovascular Surgery, Fujian Provincial Hospital in January 2006 -2010 in October of 199 routine CABG surgery patient data. Through retrospective analysis of clinical data, the selected gender, age, weight, smoking, hypertension, history of diabetes, high cholesterol, a merger of the valve disease, preoperative pulmonary function, preoperative cardiac function, coronary lesion count, whether by the CPB factors as the study of the CPB time, intraoperative transfusion, blood transfusion, merge the same period surgery. General Statistical Analysis System SPSS 13.0 statistical analysis Measurement data were expressed as mean ± standard deviation (x_ ± s), using two independent samples t-test, x2 test, test, α = 0.05 for significance test standard. Filter out the risk factors associated with the CABG postoperative pulmonary complications, and prevention of hypoxia in patients with treatment recommendations. Results: 199 cases of CABG patients, 85 cases of postoperative pulmonary complications, including hypoxemia 74 cases, ARDS13 of cases, 39 cases of lung infection, 64 cases of interstitial lung water, respiratory failure in 2 cases. Recovered and were discharged after treatment of 79 patients, four cases of postoperative low cardiac death, two cases of death due to a severe lung infection and ARDS. Factors studied, age, hypertension, preoperative lung disease, heart dysfunction, combined valvular disease, blood transfusion, CPB time, merge the same period other surgery eight factors were statistically significant. Conclusion: 1.CABG postoperative pulmonary complications affecting patients with postoperative recovery, extended stay SICU time and the number of hospital days. 2.CPB time and intraoperative blood transfusion impact CABG incidence of postoperative pulmonary complications. CPB is the longer, more blood transfusion, the higher the incidence of postoperative pulmonary complications. Old age, hypertension, the preoperative lung diseases, combined valve disease, cardiac dysfunction in the preoperative and postoperative pulmonary complications have a significant correlation. 4 gender, high cholesterol, and the CABG postoperative pulmonary complications was no significant correlation. 5. Obesity, smoking, diabetes, cardiopulmonary bypass surgery and CABG in the same period of postoperative pulmonary complications relationship needs further study.
