Flow-Controlled Ventilation to Improve Postoperative Pulmonary Outcome After Thoracic Surgery

In an international multicenter randomized clinical pilot trial, intraoperative flow-controlled ventilation (FCV) will be compared with volume-controlled ventilation (VCV) in patients scheduled for (open, video- or robot-assisted) thoracic surgery with one-lung ventilation (OLV). This pilot trial is designed to test the feasibility and safety of FCV during all phases of intraoperative ventilation, and in particular during OLV, and to inform the design of a future trial testing the efficacy of FCV with regard to postoperative outcomes, including postoperative pulmonary complications (PPC). The ventilation modes are conducted with CE-marked medical devices (anesthesia ventilators or medical ventilators), however these medical devices themselves are not under investigation. All CE-marked standard medical devices from varied manufacturers in use at the participating study centers will be used in full accordance with their instructions for use. FCV has shown safety and feasibility in various surgical settings, including thoracic surgery with OLV, however its feasibility in a multicenter trial has not been investigated yet.
