AbstractLimited data are available on the use of the prone position in cardiac surgery. Concerns in performing this maneuver in open cardiac surgery due to the risk of post-sternotomy wound infections and hemodynamic instability do not seem to be supported by existing evidence. Indeed, available data show that prone positioning may improve gas exchange in cardiac surgery patients as well. However, previous studies of prone positioning in this setting were heterogeneous in patient characteristics and outcomes evaluated. As a result, whether prone positioning also may be effective in reducing mortality in patients with postoperative acute respiratory failure, particularly in those who underwent surgery under extracorporeal circulation, remains to be clearly elucidated. The aim of this article is to provide an overview of available literature, which seems to suggest the efficacy of prone positioning, and to make an in-depth analysis of the studies on this topic by evaluating the efficacy of this maneuver on hard endpoints.Copyright © 2021 Elsevier Inc.
