[Study on gas exchange of the patients with lung cancer in perioperation]
1Cardiopulmonary Laboratory, Beijing Tuberculosis & Thoracic Research Institute, Beijing 101149.
Objective:
To study changes of gas exchange in perioperative patients with lung cancer.
Method:
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.
Result:
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.
Conclusion:
The gas exchange of the patients with lung cancer reduced significantly in postoperative 3 days.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
