Usefulness of Arterial Pressure-Based Cardiac Output(APCO) and Stroke Volume Variation(SVV) to Determine Fluid Therapy in the Perioperative Period of Esophagogastrectomy

Abstract

The aim of this study was to assess the usefulness of an arterial pressure-based cardiac output(APCO) monitoring system in the postperative management of patients undergoing esophagectomy. The FloTrac monitor(Edwards Lifescience) was used in three extubated patients who underwent radical operation for transthoracic esophagectomy with three field lympho node resection. Stroke volume variation, calculated for each respiratory cycle and displayed on the Vigileo monitor, could predict intravascular hypovolemia. It is suggested that the Vigileo monitor with FloTrac is an accurate predictor of intravascular hypovolemia and is a useful indicator for assessing the appropriateness and timing of applying fluid for improving circulatory stability during the postperative period of esophagectomy under spontaneous respiration.
