Open Access Abstract Introduction Several studies have shown that maximizing stroke volume or increasing it until a plateau is reached by volume loading during high-risk surgery may improve post-operative outcome. This goal could be achieved simply by minimizing the variation in arterial pulse pressure APP induced by mechanical ventilation. We tested this hypothesis in a prospective randomized single-centre study. The primary endpoint was the length of postoperative stay in hospital. Methods Thirty-three patients undergoing high-risk surgery were randomized either to a control group group C n 16 or to an intervention group group I n 1 7 . In group I APP was continuously monitored during surgery by a .
