The influence of PEEP and positioning on central venous pressure and venous hepatic hemodynamics in patients undergoing liver resection

摘要

Purpose In order to assess the occurrence of blood congestion in the liver during liver resection, we aimed to evaluate the influence of a positive-end-expiratory-pressure (PEEP) and positioning of patients on central venous pressure (CVP) and venous hepatic blood flow parameters. We further analyzed correlations between CVP and venous hepatic blood flow parameters.
