Evaluation of Effect of Lung Resection on Lobar Ventilation and Perfusion Using Intrabronchial Capnography

Intrabronchial capnography was applied in 11 lung cancer patients to investigate the effects of lobectomy on regional lung function. Spirometry and intrabronchial capnography were performed before surgery (PRE), and during the early (POST1,19±5 POD) and late (POST2, 184±98 POD) postoperative periods...

Zusammenfassung:	Intrabronchial capnography was applied in 11 lung cancer patients to investigate the effects of lobectomy on regional lung function. Spirometry and intrabronchial capnography were performed before surgery (PRE), and during the early (POST1,19±5 POD) and late (POST2, 184±98 POD) postoperative periods. End-tidal carbon dioxide concentration (EtCO2) and Smidt's velocity profile index (V-index) were calculated from each lobar capnogram obtained bronchoscopically. The V-index of lobes without cancer on the operated-on side increased after surgery (PRE, 10.7± 5.0%; POSTI, 14.3±9.4%, NS; POST2, 16.8±8.6%, p
