Abstract
BACKGROUND: There are incresing lung cancer patients detected and diagnosed at the intermediate stage when the pre-malignant or early lesions are amenable to resection and cure, owing to the progress of medical technology, the renewal of detection methods, the popularity of medical screening and the improvement of social health consciousness. The aim of this study is to investigate the risk factors of the occurrence of postoperative cardio-pulmonary complications in stage I non-small cell lung cancer (NSCLC) patients, based on routine laboratory tests, basic characteristics, and intraoperative variables in hospital.Entities:

心肺相关并发症诊断标准
Criterion of cardio-pulmonary complications
| Arhythmia | Requiring pharmacological treatment or interventions by cardiologists |
| WBC: white blood cell; VATS: video assisted thoracic surgery; CT: computed tomography. | |
| Pneumonia | 1: Fever as seen by raised oral temperature of >38 ℃ with no focus on outside of the lungs. The highest temperature within the previous 24 h will be reported; |
| Atelectasis | 1: Chest radiograph showing atelectasis/consolidation; |
| Pulmonary embolism | 1: Pulmonary artery angiography showing embolism; |
| Respiratory/heart failure or ADRS | Needing trachea cannula, Ventilator maintenance or intensive care |
| Bronchopleural fistula | Bronchofiberscope showing bronchopleural fistula |
| Aerodermectasia | 1: Persisting >15 d; |
| Hemoptysis | 1: Persisting >3 d and inefficacy of pharmacological treatment; |
| Pleural effusion (≥middle) | 1: Drainage time >15 d; |
| Chylothrax | 1: Raily drainage volume >500 mL (>3 d, under ambrosia condition) and requiring pharmacological treatment (like interleukin-2); |
| Air leak | 1: Persisting for over 15 d; |
