Does prone position affect stroke volume variation performance in predicting fluid responsiveness in neurosurgical patients?
In ventilated patients with low tidal volume, a prone position may have a direct effect on the heart that alters the performance of SVV in predicting fluid responsiveness. External factor such as prone position renders difficult the interpretation of SVV as a dynamic indicator of cardiac preload.
The number of involved extracranial organs is an independent prognostic factor of survival in SCLC patients with brain metastasis.
