Objective： To analyze the tolerance of lung cancer patients with moderate pulmonary hypofunction to open-chest operation. Methods： The postoperative complications of 31 patients with moderate pulmonary hypofunction （study group） and 62 patients with normal pulmonary function （control group） were reviewed. Statistical t test and χ^2 test were set to examine the data, and logistic regression was performed to find the associated factors. Results： In patients with moderate pulmonary hypofunction, hypoxemia （41.9%）, arrhythmia and cardiac dysfunction （25.8%）, and pulmonary inflammation （25.8%） were common postoperative complications, and respiratory failure and cardiac failure （9.2%） severe complications. In-hospital mortality rate was 3.2%. In the control group, the incidence of the above 4 postoperative complications was 16.1%, 8.1%, 9.6% and 3.2% accordingly, and no case died in hospital. Regression analysis showed that age and resection range were associated with the occurrence of the complications. Conclusion： Common postoperative complications （hypoxemia） in patients with moderate pulmonary hypofunction are remarkably higher than those in control group, but severe complications and in-hospital mortality rate are not significantly high. Patients with older age and larger resection range undergo higher complication rate.
