Background:
To analyze the perioperative respiratory and circulatory features of overweighted patients with lung cancer.
Methods:
The perioperative respiratory and circulatory features of 221 overweighted lung cancer patients were compared with those of 715 normal-weighted patients, by means of Chi-square analysis and t analysis.
Results:
The abnormal incidence of MBB, Raw, SGaw, PEF, FEV₁, V₇₅ , and EEG, blood presure, serum cholesterol and glucose, was significantly higher in overweighted group than that in the normal weighted group ( P < 0.05), and FRC was significantly lower than that of the normal weighted group (3.46±0.87 vs 3.63±1.17, P < 0.01). There was no difference in D LCO, MMEF, V₅₀ , V₂₅ between the two groups. The odds of postoperative complication in respiratory or circulatory system was significantly increased in overweighted group than that in the normal weighted group.
Conclusions:
The obstruction of main airway, partial alveolar collapse and impotency of respiratory muscle may result in respiratory complication in overweighted patients, and increased cardiac burden and some pre-existing diseases in overweighted patients might be the cause of increased incidence of circulatory complication.

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.
