Summary

Background: Anesthesia in free flap surgery is challenging. Monitoring of hemodynamic changes and their influence on the cardiovascular system in permanent feedback loops allow control, which is what anesthesiologists aim for to ensure an adequate blood flow and tissue oxygenation. The circulatory support and inferable volume administration are managed via heart rate (HR) and mean arterial pressure (MAP), but both parameters are influenced by variable components and are thus unfavorable for volume management. The aim of this study was to evaluate whether volume requirement may be assumable to additional monitoring parameters.

Methods: 31 patients were enrolled prospectively. HR, MAP, central venous pressure and O2 saturation were comprehended based on the protocols. We expanded the data set by a permanent blinded intraoperative monitoring with registration of the Cardiac Index (CI) and Stroke Volume Variation (SVV) and semi-invasive pulse-contour analysis utilizing the Pro-AQT-Device.
