Invasive central venous monitoring during hepatic resection: unnecessary for most patients.

Background: Low central venous pressure (LCVP) anesthesia reduces blood loss during hepatic resection and historically has required a central venous catheter (CVC) for intra-operative monitoring. The aim of this study was to assess the effect of an evolution of practice to CVP monitoring without CVC on the perioperative outcomes after liver resection.

Methods: A retrospective study of partial hepatectomy patients from 2007 to 2016 who were over 18 years of age was performed.
