Excessive fluid balance effect in mortality rate from surgical patients

In some studies including small populations of patients undergoing gastrointestinal surgery, a liberal infusion of fluids during the intraoperative period was associated with increased morbidity when compared with restrictive strategies for volume replacement. However, there are few studies evaluating the role of excessive fluid infusion in a population of high-risk surgical patients intraoperatively. The aim of this study was to evaluate the impact of the excessive water balance in the perioperative morbidity and mortality of high-risk surgical patients.
