Pulmonary complications are the most common complication in thoracic surgery and the leading cause of mortality.Therefore, lung protection is utmost important, and protective ventilation is strongly recommended in thoracic surgery. Protective ventilation is a prevailing ventilatory strategy in these days and is comprised of small tidal volume, limited inspiratory pressure, and application of positive end-expiratory pressure. However, several retrospective studies recently suggested that tidal volume, inspiratory pressure, and positive end-expiratory pressure are not related to patient outcomes, or only related when they influenced the driving pressure. Recently, the investigators reported the first prospective study about the driving pressure-guided ventilation in thoracic surgery. PEEP was titrated to bring the lowest driving pressure in each patient and applied throughout the one lung ventilation. The application of individualized PEEP reduced the incidence of pulmonary complications.However, that study was small size single center study with 312 patients. Thus, investigators try to perform large scale multicenter study. Through this study investigators evaluate that driving pressure-guided ventilation can reduce the incidence of postoperative pulmonary complications compared with conventional protective ventilation in thoracic surgery.

Primary | the incidence of postoperative pulmonary complications | Postoperative pulmonary complications are defined as one or more of the following:
Hypoxia: SpO2 < 90% Requiring oxygen therapy: Facial mask, nasal prong, continuous positive airway pressure, non-invasive positive pressure breathing or high flow nasal oxygen supply between POD 2 and 7. Initial ventilator supports longer than 24 h Re-intubation Requiring mechanical ventilation Tracheostomy Pneumonia Empyema Atelectasis requiring bronchoscopy Acute respiratory distress syndrome Acute lung injury Persistent emphysema or pneumothorax or air leak requiring chest tube for 5 days or more Prolonged pleural effusion requiring chest tube for 5 days or more Bronchopleural fistula Contralateral pneumothorax Pulmonary embolism embolism |
within the first 7 days after surgery | |
Secondary | oxygenation | Partial pressure of oxygen in arterial blood (PaO2, mmHg) or PaO2/Inspired oxygen fraction (PF ratio) | 15 minutes after one-lung ventilation | |
Secondary | the incidence of rescue ventilation | the need for rescue ventilation to treat hypoxia (Inspired oxygen fraction 1.0, two lung ventilation, recruitment, PEEP change, Tidal volume change, continuous positive pressure ventilation, change to pressure control mode) | during surgery | |
Secondary | Cstat | Lung compliance (mL/mmHg) | 15 minutes after one-lung ventilation | |
Secondary | CRP | C-reactive protein (mg/L) of laboratory exam | within the first 1 days after surgery | |
Secondary | the incidence of postoperative transfusion | red blood cell, fresh frozen plasma, platelet | within the first 3 days after surgery | |
Secondary | the incidence of postoperative renal complications | acute kidney injury(acute kidney injury network criteria): Stage I: Diuresis < 0.5 mg/kg (6 h) or increase in serum Cr > 0.3 mg/dl. Stage II: Diuresis < 0.5 mg/kg (12 h) or basal Cr x 2 mg/dL. Stage III: Diuresis < 0.3 mg/kg (24 h) or anuria (12 h) or basal Cr x 3 mg/dL, or Cr > 4 mg/dL or renal replacement therapy. | within the first 7 days after surgery | |
Secondary | the incidence of postoperative cognitive complications | diagnosed by Confusion Assessment method (CAM: positive or negative) or Medicines for treating delirium symptoms include antipsychotic drugs and benzodiazepines | within the first 7 days after surgery | |
Secondary | the incidence of postoperative surgical site complications | : The CDC defines a superficial incisional surgical site infection as one which meets the following criteria.
Infection occurs within 30 days after surgery and Involves only skin and subcutaneous tissue of the incision and The patient has at least one of the following: purulent drainage from the superficial incision organisms isolated from an aseptically obtained culture of fluid or tissue from the superficial incision at least one of the following symptoms or signs of infection: pain or tenderness, localised swelling, redness or heat, and superficial incision is deliberately opened by surgeon and is culture positive or not cultured. A culture negative finding does not meet this criterion. diagnosis of an incisional surgical site infection by a surgeon or attending physician. |
within the first 7 days after surgery | |
Secondary | the incidence of acute myocardial infarction | Acute myocardial injury with clinical evidence of acute myocardial ischemia and with detection of a rise and/or fall of cardiac troponin values with at least one value above the 99th percentile upper reference limit and at least one of the following:
Symptoms of myocardial ischemia New ischemic ECG changes Development of pathological Q waves Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality in a pattern consistent with an ischemic etiology Identification of a coronary thrombus by angiography or autopsy (not for types 2 or 3 myocardial infarctions) |
within the first 7 days after surgery | |
Secondary | the incidence of coronary thrombosis | Percutaneous coronary intervention or coronary artery surgery | within the first 7 days after surgery | |
Secondary | the incidence of cerebral infarction | Magnetic resonance imaging diagnosis | within the first 7 days after surgery | |
Secondary | the incidence of septic shock | : A subset of sepsis (a life-threatening organ dysfunction resulting from dysregulated host responses to infection) in which underlying circulatory, cellular, and metabolic abnormalities are profound enough to substantially increase the risk of mortality. Despite adequate fluid resuscitation, patients have hypotension requiring vasopressors to maintain a mean arterial blood pressure above 65 mmHg and have an elevated serum lactate concentration of more than 2 mmol/L | within the first 7 days after surgery | |
Secondary | the incidence of new arrythmia | New arrhythmias that persist for more than 2 days | within the first 7 days after surgery | |
