Table 3 StO2 values (median [25thto 75thpercentiles]) of the 54 trauma patients with haemorrhagic shock collected 6 hours (H6) and 72 hours (H72) after their arrival at the emergency room

From: Skeletal muscle oxygenation in severe trauma patients during haemorrhagic shock resuscitation

  1. Patients were separated into two groups according to whether they subsequently improved or not their initial SOFA score (see definition Table 1). aNine patients died between H24 and H72 in SOFA non-improvers. *P <0.05 vs SOFA improvers. StO2, tissue haemoglobin oxygen saturation; SOFA, sequential organ failure assessment; VOT, vascular occlusion test; DS-StO2, StO2 desaturation slope; RS-StO2, StO2 slope.
