[Articles] Effects of intraoperative higher versus lower positive end-expiratory pressure during one-lung ventilation for thoracic surgery on postoperative pulmonary complications (PROTHOR): a multicentre, international, randomised, controlled, phase 3 trial

In patients with a BMI of less than 35 kg/m2 undergoing thoracic surgery, one-lung ventilation using higher PEEP with recruitment manoeuvres, compared with lower PEEP without recruitment manoeuvres, did not reduce PPCs. The choice for intraoperative lung expansion or permissive atelectasis should take the individual gas-exchange and haemodynamic conditions into account, which might vary during the intraoperative period.
