Using perioperative goal-directed therapy (GDT) or peroperative hemodynamic optimization significantly reduces postoperative complications and risk of death in patients undergoing noncardiac major surgeries. In this review, we discuss the main changes in the field of perioperative optimization over the last few years. ⋯ GDT is safe and more likely to tailor the amount of fluids given to the amount of fluids actually needed. This approach includes assessment of fluid responsiveness and, if necessary, the use of inotropes; moreover, this approach can be coupled with a restrictive strategy for maintenance fluids. These strategies have been increasingly incorporated into protocols for perioperative hemodynamic optimization in high-risk patients undergoing major surgery, resulting in more appropriate use of fluids, vasopressors, and inotropes.

There is significant controversy for perioperative fluid management. This review discusses the evidence from clinical studies, basic research, and systematic reviews to provide a summary of the current best practice in this area. ⋯ Although potentially life-saving, evidence points to significant hazards associated with various types and use-strategies for intravenous fluids. Like other drugs, intravenous fluids should be used with caution for specific indications, in specific amounts, and with careful attention to potential adverse effects associated with various products. An individualized approach to perioperative fluid therapy is recommended.

Resuscitation with hydroxyethyl starch (HES) is controversial. In this review, we will present the current evidence for the use of HES solutions including data from recent high-quality randomized clinical trials. ⋯ There is no evidence for an overall beneficial effect of HES in any subgroup of critically ill patients, but there are clear signs of harm. As safer alternatives exist, we recommend that HES is no longer used in critically ill patients.

Fluid resuscitation is a common intervention in acute medical practice. The optimum fluid for resuscitation remains hotly debated and it is likely to vary from one clinical situation to another. Human albumin solutions have been available since the 1940s, but their use varies greatly around the world. This review examines the current evidence for and against the use of albumin as a resuscitation fluid. ⋯ Fluid resuscitation with albumin is well tolerated and produces similar results to resuscitation with saline. Albumin should be avoided in patients with traumatic brain injury; possible benefits in adults with severe sepsis remain to be confirmed.
