Passive leg raising and microvascular skin blood flow to predict peripheral tissue perfusion fluid responsiveness.

Key Points

• To determine if passive leg raising can predict skin blood flow changes in septic patients during volume expansion.
• Conducted in septic patients
• Measured skin blood flow changes during passive leg raising
• Evaluated responsiveness to subsequent volume expansion
• Passive leg raising induced significant changes in skin blood flow
• Changes reliably predicted peripheral microvascular responsiveness
• Suggests potential for personalized fluid strategies
