Malignancy
NO
Intermittent reinflation as repeated cycle of collapse and re-expansion of operated lung is a suggested maneuver for the prevention of hypoxemia during one lung ventilation but may impose mechanical stress for operated lung. We hypothesized that intermittent reinflation may increase extravascular lung water leading to lung injury. To test the hypothesis, we will measure extravascular lung water with or without intermittent reinflation.
Safety,Efficacy
The primary outcome is set to the change of extravascular lung water with PiCCO (Pulsion Medical Systems, Munich, Germany) determined with the single indicator transpulmonary thermodilution technique at T1; baseline time after induction of anesthesia, T2; the end of the surgical procedure and before extubation, T3; just after the admission to the ICU, and T4; 12 hour after the admission to the ICU, respectively.
Secondary outcome includes postoperative complications within 14 days and duration of postoperative hospitalization.

Treatment
Maneuver |
Patients are randomly assigned to either group C or group IR. Group C that is control group consists of patients whose nondependent lung is kept collapsed during OLV.
Group IR that is intervention group includes patients with intermittent reinflation that consists of quadruple of 10-second manual inflation and 5-second open within a minute at intervals of 20 minutes during OLV.

Male and Female
1) ASA physical status I-II
2) elective video-assisted thoracic surgery for lung tumor requiring one lung ventilation lasting more than 120 minutes
1) decompensated cardiac disease (> class II in New York Heart Association)
2) chronic pulmonary disease (vital capacity < 50% of predicted values and/or forced expiratory volume in 1 second < 50% of forced vital capacity)
3) chronic renal failure (serum creatinine > 1.5 mg/dl)
4) altered liver function (> class B in Child-Pugh)
5) preoperative treatment with immune modulator (cytostatic drugs, corticosteroids, nonsteroidal antiinflammatory drugs, vaccination, and blood products) within a month before surgery
6) pre-existing coagulation disorders
7) symptoms of an acute inflammatory process (clinically defined or abnormal data for C-reactive protein, leukocyte count, or body temperature)
8) Arteriosclerosis obliterans and/or iliac artery stenosis and/or aneurysms with or without bypass surgeries, which would be associated with an increased risk of complications following the femoral arterial cannulation for PiCCO
