Background:
To analyze the risky factors of post-operative respiratory failure in patients with lung cancer.
Methods:
Thirty-six cases of lung cancer with post-operative respiratory failure and 72 controls were analyzed by Chi-Square analysis and Logistic Regression.
Results:
MVV , RV/ TLC , FEV1 , BR , V25 , MMEF and DLCO in respiratory failure group were all significantly lower than those in control group ( P < 0. 05) . The post-operative chest drainage and perioperative intravenous perfussion in respiratory failure group were significantly more than those in control group ( P < 0. 05) . The odds of respiratory failure was much lower in sleeve resection and lobectomy group than in pneumonectomy group.
Conclusions:
Severe obstruction of small airway , diffusion capacity and large amount perioperative intravenous infusion are the risky factors of post-operative respiratory failure in lung cancer patients , and bronchoplastic or/ and pulmonary artery reconstruction as a curative operation can significantly prevent the post-operative respiratory failure.

Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
