the ‘Local ASsessment ofVEntilatory management during General Anaesthesia for Surgery’ (LAS VEGAS) worldwide multicenter observational study in 10520 patients in 146 countries described the epidemiology, ventilation practive and outcome of patients receiving intraoperative ventilation under general anesthesia for surgery

LAS VEGAS is registered at clinicaltrials (NCT01601223); the study protocol was partly published in European Journal of Anaesthesiology (2013; 30:205); the primary analysis was published in European Journal of Anaesthesiology (2017; 34:492)

the database of LAS VEGAS is and will be harmonized with those from other observational studies in a pooled database

connect with Sabrine Hemmes or Lorenzo Ball for secondary analyses of the LAS VEGAS database

the ‘Assessment of Ventilation during general AnesThesia for Robotic surgery’ (AVATaR) multicenter observational study in 1015 patients in 34 centers described the epidemiology, ventilation practive and outcome of patients receiving intraoperative ventilation under general anesthesia for abdominal robotic–assisted surgery

AVATaR is registered at clinicaltrials (NCT02989415); the primary analysis was published in British Journal of Anaesthesiology (2020; 126:553)

the database of AVATaR is and will be harmonized with those from other observational studies in a pooled database

connect with Ary Serpa Neto for secondary analyses of the AVATaR database

the ‘Incidence of postoperative pulmonary complications in patients with a positive and negative AIR-Test during general Anesthesia’ (AIRTEST) singlecenter observational study describes the incidence of PPCs in patients with a positive and negative AIR–test result in 632 patients under general anesthesia for surgery

AIRTEST is registered at clinicaltrials (NCT05345743)

the database of AIRTEST will be harmonized with those from other observational studies, like LAS VEGAS and AVATaR in a pooled database

the database of AIRTEST is not yet available for secondary analyses

the ‘Current Practice of Ventilation Strategies in Children undergoing General Anesthesia and Associations with Postoperative Pulmonary Complications’ (BIG APPLE) is a new worldwide multicenter observational study that will describe the epidemiology, ventilation practive and outcome of pediatric patients receiving intraoperative ventilation under general anesthesia for surgery

BIG APPLE will be registered at clinicaltrials (pending); the study protocol will  be published soon

the database of BIG APPLE will be harmonized with those from other observational studies, like LAS VEGAS, and AVATaR in a pooled database

the database of BIG APPLE is not yet available for secondary analyses
