Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the reliability of changes in pulse pressure variation (PPV) & stroke volume variation (SVV) values induced by tidal volume challenge in predicting fluid responsiveness in patients undergoing neurosurgery in the sitting position under 6 ml/kg (PBW)Timepoint: To assess the reliability of changes in pulse pressure variation (PPV) & stroke volume variation (SVV) values induced by tidal volume challenge in predicting fluid responsiveness in patients undergoing neurosurgery in the sitting position under 6 ml/kg (PBW) | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess the reliability of pulse pressure variation (PPV) & stroke volume variation (SVV) at 6 ml/kg & 8 ml/kg.Timepoint: Starting point - At the point when sitting postion of the patint is achieved with hemodynamic stability. End Point - At the point when Hemodynamic parameters are noted after the fluid challenge. | — |
