Individualised Target

Post-operative morbidity and mortality is related to many factors related to the patient's condition, the intra-operative period and the optimisation of intra-operative haemodynamic and respiratory parameters. Many studies have looked at the determinants and factors that increase postoperative complications. However, these have been randomised studies looking at one parameter in particular. This analysis would be the first to investigate the determinants of postoperative complications in a large population of patients undergoing major non-cardiac surgery. This is a post-hoc analysis of patients included in the OPHIQUE study, whose main objective was to evaluate intraoperative haemodynamic management guided by a marker of tissue hypoperfusion (the respiratory quotient).
