Key result
Plethysmographic dynamic indices predicted fluid responsiveness similarly to direct arterial blood pressure measurement (AUC 0.72 vs 0.74, P=0.90).
Why the study?
Do plethysmographic dynamic indices predict fluid responsiveness as accurately as arterial dynamic indices in hypotensive patients?
Population

May support noninvasive plethysmographic indices as arterial alternatives for fluid responsiveness in hypotensive patients; leaves open randomized validation.

Do plethysmographic dynamic indices predict fluid responsiveness as accurately as arterial dynamic indices in hypotensive patients?
Effect estimate: AUC 0.72 vs 0.74
p-value: p=0.90
Noninvasive plethysmographic dynamic indices are as useful as direct arterial blood pressure indices for predicting fluid responsiveness in hypotensive patients.
Natalini et al. (2006) conducted an observational in Hypotension (n=22). Plethysmographic dynamic indices vs. Direct arterial blood pressure measurement indices was evaluated on Prediction of fluid responsiveness (cardiac index increase by 15% from baseline) (AUC 0.72 vs 0.74, p=0.90). Plethysmographic dynamic indices predicted fluid responsiveness similarly to direct arterial blood pressure measurement (AUC 0.72 vs 0.74, P=0.90).
