Abstract:
Objective To evaluate the possibility of using preoperative conventional lung function tests and impulse oscilloresistometry system (IOS) to predict the development of postoperative respiratory failure after radical lung cancer surgery in patients with poor pulmonary function. Methods Fifty-two male patients with lung cancer between 51-63 yrs undergoing radical lung cancer surgery were included in this study. Preoperative pulmonary function was assessed by conventional lung function tests ( FEV1.0 , VC, MVV) and impulse oscilloresistometry system (IOS) (peripheral airway resistance R5-R20; elastic resistance ( X5 ) and Fres. Postoperative respiratory failure was defined as short of breath (SOB) , cyanosis, SpO2 45 mm Hg.Results Nine patients developed postoperative respiratory failure (17.3%). There was significant difference in FEV1.0 , R5-R20, X5 and Fres between patients who developed postoperative respiratory failure and those who did not. Logistic regression analysis showed that Fres is an independent factor predicting respiratory failure. Conclusion Fres is an important parameter of impulse oscilloresistometry system (IOS) for prediction of postoperative respiratory failure after lung cancer surgery in patients with poor pulmonary function.
