Skeletal muscle oxygenation in severe trauma patients during haemorrhagic shock resuscitation

Table 2 Physiological variables (n or median [25^thto 75^th percentiles]) of the 54 trauma patients with haemorrhagic shock collected 6 hours (H6) after their arrival at the emergency room

Patients were separated into two groups according to whether they subsequently improved or not their initial SOFA score (see definition Table 1). *P <0.05 vs SOFA improvers. SBP, systolic blood pressure; CI, cardiac index; BE, base excess; PTT, partial thromboplastin time; PRBCs, packed red blood cells; FFP, fresh frozen plasma; SOFA, sequential organ failure assessment.
