BACKGROUND Measurement of functional residual capacity (FRC) is now possible at bedside, during mechanical ventilation. OBJECTIVES To determine the relationship of measured absolute and relative predicted FRC values to oxygenation and respiratory-system compliance, and to identify variables that influence FRC in ventilated patients after cardiac surgery.… (More)
BACKGROUND To counteract the contribution of angiotensin II to shock-induced ischaemic organ damage pharmacologic blockade of the renin-angiotensin-system (RAS) is currently under investigation. To evaluate potential side-effects of RAS blockade regarding capillary leak, we studied alterations in microvascular permeability in various organs during… (More)
The authors considered three protocols for spinal anesthesia using sheep as a model. An appropriate spinal anesthesia method would obviate the need for general anesthesia in certain surgical approaches.
