[Changes in acid-base equilibrium, ventilation parameters and immunologic reactions in thoracoscopic operations].

In the thoracoscopic operations it is usually necessary to deflate completely the ipsilateral lung. The aim of this study was to determine changes of blood gases and alterations of immune response mediators during thoracoscopic surgery with one-lung ventilation OLV. In the study 38 patients were included undergoing thoracoscopic or video-assisted thoracic surgery.
