Exercise test as preoperative predictor before pulmonary resection surgery

Exercise test (V02) before pulmonary resection surgery was incorporated into the new guidelines (A.Brunell Eur Respir J 2009; 34: 17-41) in the case that the patient presents a FEV 1 and/or TlCO Material and methods: prospective descriptive study, three months, which included 48 patients evaluated for possible lung resection due to lung neoplasm who presented values less than 80% in the FEV1 or TlCO and preformed a maximum exercise testing to complete the preoperative assessment. Results: mean age (65±8 years); 41 M, 7F. According to the retrieved V02 patients were divided in 3 groups and comparing the values of the FEV 1 and TlCO in each group Table I. 25 patients presented a DLCO and FEV1% 20. Correlations between FEV1 vs VO2 (0,478,P 28/48 patients were operated and in the postoperative follow up(1 month) there was no death and 8 (28.5%) of them had postoperative complications(2 empyema 2 hemothorax,1 fistula 2 pneumonia.,1respiratory failure) These patients presented the following functional parameters FEV1 1686ml, DLCO 51.8%, 17.4 ml/kg/min V02.Conclusions: Patients with mechanical and/or decreased gas exchange (
