Editorial comment to intraoperative haemodynamic monitoring and management of adults having non-cardiac surgery: guidelines of the German society of Anaesthesiology and Intensive care medicine in collaboration with the German Association of the Scientific medical societies

In this issue, the German Society of Anaesthesiology and Intensive Care Medicine in collaboration with the German Association of the Scientific Medical Societies provide guidelines on intraoperative haemodynamic monitoring and management of adults having non-cardiac surgery. The document brings together a broad variety of data regarding perioperative haemodynamic management. Although a wide range of studies have been covered, no systematic literature search was conducted, and the methodology for appraising the evidence and formulating the recommendations is not described. Therefore, these guidelines should be viewed as a consensus of expert opinions, with questions identified by anaesthesiologists from three German university hospitals.
