Sequential Compression Device (SCD) for Stabilizing Hemodynamics in the Beach Chair Position

Stabilizing Cerebral and Circulatory Hemodynamics During Shoulder Surgery in the Beach Chair Position Using Sequential Compression Device (SCD) or TED Stockings Compared to a Control Group

This study is a 3-legged randomized study examining whether during shoulder surgery performed in the beach chair position active compressions of the lower leg with a sequential compression device (SCD) have a superior effect on stabilizing cerebral and circulatory hemodynamics when compared to TED stockings or a control group without any stockings.
