Brief Summary: Chronic obstructive pulmonary disease (COPD) patients often undergo thoracic surgery due to lung cancer and emphysematous changes. One lung ventilation (OLV) used in thoracic surgery aggravates hypoxia and hypercapnia increasing intrapulmonary shunt and dead space.Ketamine provide bronchodilation by inhibiting the reuptake of catecholamines in the circulation. It also serves relaxation of bronchial smooth muscle. Our aim in this study, effects of ketamine on arterial oxygenation, the shunt fraction and the lung mechanics in patients with COPD who administered OLV because of thoracic surgery. Thirty patients with COPD who undergo thoracotomy for lung lobectomy will be included in this study. Patients will be randomly divided to a control group (%0,9 saline- CG) or a keta (ketamine- KG) group. KG will be administered 1 mg/kg ketamine bolus, then 0,5 mg/kg/hour ketamine infusion after the induction, CG will be administered sline bolus, then saline infusion. Peak airway pressure (Ppeak), plato airway pressure (Pplato), static compliance, shunt fraction, PaO2/FiO2 and arteriel blood gas values (Pa02, PaC02) will be recorded before initiation of OLV and 30 minutes intervals after initiation of OLV.To evaluate the postoperative pulmonary complications, Pa02, PaC02 in blood gas and Pa02/Fi02 values will be recorded 20 minute after arrival at postoperative care unit. Patients will be evaluated for pneumonia, atelectasis and acute lung injury at postoperative 72 h and findings will be recorded. 30 day mortality will be recorded.
