Perioperative monitoring of fluid responsiveness after esophageal surgery using stroke volume variation

Presented at:The 107th Annual Congress of Japan Surgical Society, Osaka International Convention Center, Japan, 11–13 April 2007.Objective: To assess the utility of a new arterial pressure-based cardiac output (FloTrac™) and central venous oximetry (PreSep™) monitoring system in the perioperative management of patients undergoing radical esophagectomy.Case series: From May 2006, a new analyzing device (Vigileo™ monitor; Edwards Lifesciences LLC, Tokyo, Japan), which can be used in combination with the FloTrac™ and PreSep™ sensors, has been used in nine patients who have undergone radical operations for thoracic esophageal cancer at our hospital. Stroke volume variation (SVV), calculated for each respiratory cycle and displayed on the Vigileo monitor, precisely predicted intravascular hypovolemia. The maximum SVV of patients who needed fluid resuscitation was significantly higher than that of patients who had a stable circulation. The mean value of the maximum SVV in the patient with or without fluid resus...
