Why the study?

Does femoral dP/dtmax accurately reflect left ventricular contractility independent of loading conditions in critically ill patients?

Structured PICO

Does femoral dP/dtmax accurately reflect left ventricular contractility independent of loading conditions in critically ill patients?

Population

19 critically ill patients with cardiovascular failure

Intervention

Hemodynamic interventions including dobutamine infusion, volume expansion, passive leg-raising, and norepinephrine

Comparator

Baseline measurements before interventions

Outcome

Changes in femoral dP/dtmax and its correlation with arterial pulse pressure (PP)surrogate

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Femoral dP/dtmax is strongly influenced by pulsatile arterial load and loading conditions, and thus may not be directly interchangeable with left ventricular contractility in critically ill patients.
