Multimodal assessment of peripheral perfusion in critically ill patients: a pilot study.

ABSTRACT:

Background

Impaired peripheral perfusion is linked to poor outcomes in critically ill patients, but the relationships among common bedside assessment tools remain unclear. This study aimed to evaluate whether these parameters provide overlapping or complementary prognostic information across ICU subgroups.

Methods

Adult ICU patients with an expected stay ≥ 3 days were included. On day 1, six peripheral perfusion parameters were simultaneously measured: Peripheral Perfusion Index (PPI), Mottling Score (MS), Capillary Refill Time (CRT), central-to-peripheral temperature gradient (ΔT), Skin Blood Flow at basal temperature (SBF_BT), and forearm tissue oxygenation (rSO₂). The primary outcome was correlation between parameters; secondary outcomes included subgroup consis
