Popis: Background The aim of this study was to investigate whether elastic compression stockings (ECS) can affect fluid responsiveness parameters before and during passive leg raising (PLR) maneuvers. Methods In the operating room (OR), we performed a prospective study including patients referred for cardiac surgery. Blood pressure (BP), ΔPP, heart rate (HR), central venous pressure (CVP), stroke volume (SV) and aortic blood flow (ABF) (by esophageal doppler) were measured according to four conditions: supine position without ECS (baseline 1), lower limbs raised to an angle of 45° (PLR 1), returned to the supine position with ECS (baseline 2), then a second PLR maneuver with ECS was performed (PLR 2). Results Twenty patients were included. BP, SV, ABF and CVP increased significantly. ΔPP and HR decreased during PLR 1. At baseline 2, HR and ΔPP decreased significantly compared to baseline 1. During PLR 2, increase of SV (4% [9]) and ABF (4% [9]), and the decrease of ΔPP (-19% [104]) were significantly lower than those observed at PLR 1 (7% [21] P=0.05; 9% [8] P=0.02 and -66% [40] P=0.02, respectively). Eleven patients presented a ΔPP≥13% at baseline 1. Only 1 patient still presented a ΔPP≥13% with ECS at baseline 2. Only 3/9 patients with an increase of ABF ≥10% and 2/11 patients with an increase of PP ≥12% during the PLR 1 presented similar results during PLR 2. Conclusions In the OR, ECS provoke a self-fluid loading increasing ABF, decreasing ΔPP and PLR response. The presence of ECS should be considered when managing hemodynamic parameters of patients.
