Risk Factors Of Postoperative Acute Respiratory Failure In Esophageal Carcinoma And Cardiac Carcinoma Patients

Objective: To analyze the risk factors of postoperative acute respiratory failure in esophageal carcinoma and cardiac carcinoma patients. Methods: Form Jan. 1995 to Jan.2005, 42 patients with acute respiratory failure ( acute r espiratory failure group) a nd 84 random sampling(control group) after esophagectomy and cardiectomy were studied. Age,sex, smoke index, preoperative respiratory function, preoperative pulmonary and the other complications, hypoproteinemia, the site of anastomosis, duration of operation, postoperative analgesia, postoperative other complications were compared by Logistic Regression analysis. Results: The risk factors of postoperative acute respiratory failure included bad preoperative pulmonary function, smoke index more than 400, preoperative pulmonary complications and duration of operation more than 3 hours(P<0.05). Conclusion: To prevent the occurrence of postoperative acute respiratory failure , improvement preoperative pulmonary function, early withdrawal cigarettes, treatment pulmonary complication and decurtate operation time should be helpful.
