“UTILITY OF STROKE VOLUME VARIATION AS A PREDICTOR OF FLUID RESPONSIVENESS USING THIRD GENERATION VIGILEO DEVICE IN PATIENTS UNDERGOING BRAIN SURGERY”

Background Assessment of Stroke volume variation (SVV) using minimally invasive devices in mechanically ventilated patients has been in use for several years to guide fluid administration. This study was designed to assess the utility of SVV derived from arterial pulse contour analysis, using FloTrac/Vigileo system to predict fluid status in patients scheduled for brain surgery. Method We studied 60 adult patients undergoing brain surgery. After a 5min period of stable hemodynamic parameters post-intubation, each patient received successive volume loading steps(VLS), of 200ml lactated Ringer's solution (LR), until the increase in SV(stroke volume) was
