肺叶切除后肺功能及动脉血气改变

Pulmonary Function in the Patients Submitted to Lung Exeresis

摘要: 本文报告了80例因肺结核、肺癌行肺叶切除后患者的肺功能及动脉血气结果。不同肺叶切除对肺功能影响以右全肺切除最为严重,肺活量（VC）占预测正常值48.2%;用力肺活量（FVC）占预测正常值49.9%;第1秒用力呼气量（FEV₁）占41.5%;肺总量（TLC）占55.4%;残气量（RV）占77.6%;RV/TLC占预测正常值120.9%;用力呼气中期流速(FEF₅₀)占17.0%;(FEF₂₅)占14.3%。而对动脉血气影响不大,动脉血氧分压（P_aO₂）占预测值93.3%;氧饱和度占98.8%。

Abstract: The effects of lung surgery on respiratory function were investigated in 80 patients undering postpneumonectomy and lobectomy for carcinoma and tuberculous of the lung. The lung function showed a reduction to about half the predicted normal values for postpneumonectomy. VG was reduced to 48.2% predicted for right pneumonectomy; FVC was reduced to 49.9% predicted for right pneumonectomy; FEV1 was 41.5% predicted; TLC was 55.4% predicted; RV was reduced to 77.6%; FEF 50 was 17.0%; FEF 25 was 14.3%. It is important that protect lung function of postpneumonectomy.
