Why the study?
Does the Trendelenburg position improve cardiac preload and performance in mechanically ventilated patients with suspected hypovolemia after cardiac surgery?
Does the Trendelenburg position improve cardiac preload and performance in mechanically ventilated patients with suspected hypovolemia after cardiac surgery?
The Trendelenburg position does not significantly improve cardiac performance in hypovolemic patients after cardiac surgery, despite increasing cardiac-filling pressures.
No takes yet. Share an insight, caveat, or question.
Trendelenburg positioning does not improve cardiac performance in ventilated post-cardiac surgery patients; leaves open the value of positional preload assessment in this setting.
Reuter et al. (2003) studied this question.
