AbstractTo investigate the effect of stroke volume variability(SVV)-guided intraoperative fluid restriction on gastrointestinal functional recovery and postoperative outcome after gastrointestinal surgery. Forty ASA I-II patients undergoing elective gastrointestinal surgery were randomly divided into 2 groups (n=20 each):group A routine fluid administration and group B restricted fluid administration. SW value was maintained at 5-7 in group A and 11-13 in group B. All patients received general anesthesia, tracheal catheterized and mechanical ventilation. Hemodynamic monitoring parameters (MBP, HR, CVP, CO) were noted at 5 time points. The hemodynamic parameters were maintained within normal limits during operation in both groups. The intraoperative intravenous fluid volume in group B was significant less than in group A (p<0.01).Urine output in group A was significant less than in group B (p<0.05). Stroke volume variation measured from Edwards Flotrac sensor and Edwards Vigileo monitor could be a security and sensitive parameter as an index of volume administration. In elective gastrointestinal surgery, volume resuscitation with a goal SVV of11-13 not only reduced intravenous fluid volume but also maintained the stable hemodynamic and tissue perfusion, enhanced gastrointestinal functional recovery and reduced the length of hospital stay
