Cardiac Output Optimization on Postoperative Complications in Major Hepatic Surgery

optimization of cardiac flow by base water-electrolyte supply of 1 ml / kg / h by Ringer Lactate® and faced with any decrease of more than 10% of the VES compared to the reference VES, achievement of an optimization of the preload by administration of 250 ml of Ringer Lactate® with renewal until correction of the VES.

increase basic hydro-electrolyte supply of 6 ml / kg / h by Ringer Lactate® and 1: 1 blood loss compensation by crystalloids of the same nature.
