Perioperative fluid management in gastrointestinal surgery / 中华胃肠外科杂志

ABSTRACT

Perioperative fluid management in gastrointestinal surgery is one of the key points to maintain sufficient blood perfusion and oxygen delivery for the organs, tissues and cells. Different strategies of fluid management have different influences on postoperative complications and mortality. After systematic review of related literature, we found that compared with the conventional liberal liquid administration, restricted liquid management and goal directed liquid management would benefit patients in general. With the guidance of cardiac output (CO), stroke volume (SV), stroke volume variation (SVV), pulse pressure variation (PPV) and pulse perfusion variation index (PVI), which can dynamically monitor the reactivity to volume, individualized goal-directed liquid management was more likely to maintain the perioperative hemodynamic stability, guarantee adequate tissue and organ blood perfusion and oxygen delivery, reduce perioperative complications, and shorten the postoperative hospital stay. In addition, the potential risk of tissue hypoperfusion caused by restricted liquid management should draw the clinicians' attention. More researches are needed to explore the right timing, the appropriate type of liquid and the reasonable amount of liquid to maintain the best functional state of tissues and organs perioperatively.
