Abstract

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 <10%. Blood pressure(BP), Heart rate(HR), SV and SVV were measured before and after each VLS. We measured the optimal preload augmentation required for each patient by the number of VLS after which SV increase was<10%. Results There was a statistically significant difference in base line BP and SVV but not in HR between resp...
