Effects of oxygen on post-surgical infections during an individualised perioperative open-lung ventilatory strategy: a randomised controlled trial.

Background: We aimed to examine whether using a high fraction of inspired oxygen (FIO) in the context of an individualised intra- and postoperative open-lung ventilation approach could decrease surgical site infection (SSI) in patients scheduled for abdominal surgery.

Methods: We performed a multicentre, randomised controlled clinical trial in a network of 21 university hospitals from June 6, 2017 to July 19, 2018. Patients undergoing abdominal surgery were randomly assigned to receive a high (0.

Association of preoperative glucose concentration with myocardial injury and death after non-cardiac surgery (GlucoVISION): a prospective cohort study.

Background: Myocardial injury after non-cardiac surgery (MINS) is the most common perioperative cardiovascular complication and is independently associated with 30-day mortality. We aimed to assess the association between preoperative glucose concentration and postoperative MINS and mortality.

Methods: The VISION study is a prospective cohort study done at 12 centres in eight countries.

Association between pre-operative biological phenotypes and postoperative pulmonary complications: An unbiased cluster analysis.

Background: Biological phenotypes have been identified within several heterogeneous pulmonary diseases, with potential therapeutic consequences.

Objective: To assess whether distinct biological phenotypes exist within surgical patients, and whether development of postoperative pulmonary complications (PPCs) and subsequent dependence of intra-operative positive end-expiratory pressure (PEEP) differ between such phenotypes.

Setting: Operating rooms of six hospitals in Europe and USA.

Individualised perioperative open-lung approach versus standard protective ventilation in abdominal surgery (iPROVE): a randomised controlled trial.

Background: The effects of individualised perioperative lung-protective ventilation (based on the open-lung approach [OLA]) on postoperative complications is unknown. We aimed to investigate the effects of intraoperative and postoperative ventilatory management in patients scheduled for abdominal surgery, compared with standard protective ventilation.

Methods: We did this prospective, multicentre, randomised controlled trial in 21 teaching hospitals in Spain.

Kinetics of plasma biomarkers of inflammation and lung injury in surgical patients with or without postoperative pulmonary complications.

Background: Postoperative pulmonary complications (PPCs) are common after major abdominal surgery. The kinetics of plasma biomarkers could improve identification of patients developing PPCs, but the kinetics may depend on intraoperative ventilator settings.

Objective: To test whether the kinetics of plasma biomarkers are capable of identifying patients who will develop PPCs, and whether the kinetics depend on the intraoperative level of positive end-expiratory pressure (PEEP).
