[Study on gas exchange of the patients with lung cancer in perioperation].
OBJECTIVE
To study changes of gas exchange in perioperative patients with lung cancer.


METHODS
Indices including P/F, a/A, P50O2 and PaCO2 on gas exchange in 68 male patients(50-78 y) with lung cancer were monitored on preoperative day 1 2 3 and postoperative day 7.


RESULTS
Comparing with preoperation data P/F a/A decreased significantly in 3 days(P < 0.01) and PaCO2 P50O2 increased significantly on the day after operation (P < 0.01), especially in the group of pneumonectomy and abnormal ventilation, hypoxemia measured in preoperation.


CONCLUSIONS
The gas exchange of the patients with lung cancer reduced significantly in postoperative 3 days.
