Brief Summary: The purpose of this study is to determine if a protective ventilatory strategy during one-lung ventilation OLV based on low tidal volume PEEP and alveolar recruitment maneuver can reduce Acute Respiratory Distress Syndrome ARDS and Postoperative pulmonary complications PPCs after major pulmonary resection

Primary endpoint Evaluation of postoperative ARDS incidence

Secondary endpoint Evaluation od PPC incidence and postoperative outcomes other complications unplanned Intensive Care Admission hospital and ICU length of stay in-hospital mortality
Detailed Description: Pulmonary postoperative complications PPCs are the most frequent adverse events after thoracic surgery Acute respiratory distress syndrome ARDS is the most severe among PPCs Injurious mechanical ventilation is a recognized risk factor associated with ARDS and PPCs after major thoracic surgery

International literature reports a wide use of tidal volume around 5-6 mlkg predicted body weight PBW during one lung ventilation OLV but variable use of PEEP and alveolar recruitment maneuver ARM

The aim of this multicenter randomized single blind study is to determine if a protective ventilatory strategy during OLV based on low tidal volume PEEP and alveolar recruitment maneuver compared to conventional strategy can reduce ARDS and PPCs after major pulmonary resection

Primary outcome is the incidence of in-hospital ARDS

Secondary outcomes are in-hospital incidence of postoperative pulmonary complications PPCs major cardiovascular events unplanned Intensive Care Unit admission in-hospital length of stay and mortality

RANDOMIZATION

Patients are randomly assigned to receive protective or conventional OLV according to a computer-generated randomization list 11 ratio before anesthesia induction

Patients are blinded to the treatment Anesthesiologists and surgeons are unblinded to the treatment during the surgical procedure and the postoperative outcome assessment

MEASUREMENTS

Intraoperative collection of ventilatory settings airway pressures arterial blood gases analysis at the following time points

T1 two lung ventilation in supine position before placing the patient in lateral decubitus T2 30 minutes after OLV start T3 60 minutes after OLV start T4 20 minutes after lobectomypneumonectomy during OLV T5 15 minutes after ARM in supine position and during two lung ventilation

Postoperative data collection 1 12 24 36 48 hours after surgery and at discharge Arterial blood gas analysis will be performed 1 hour after extubation and 24 and 72 hours after surgery or in case of respiratory insufficiency
