Skeletal muscle oxygenation in severe trauma patients during haemorrhagic shock resuscitation

Table 1 Demographic data (n or median [25^thto 75^th percentiles]) collected from the 54 haemorrhagic trauma patients on their admission to the emergency room

Intra-hospital mortality (n)	1	11^*

Patients were dichotomised according to their SOFA score changes at H72. SOFA score measured at H72 was either improved if the delta SOFA score between H72 and H6 was <0 (SOFA improvers; n = 34 patients), or unchanged or aggravated SOFA score if the delta SOFA score was ≥0 (SOFA non-improvers; n = 20 patients). ^aNine patients died between H24 and H72 in SOFA non-improvers. *P <0.05 vs SOFA improvers. BMI, body mass index; ISS, injury severity score; SAPS, simplified acute physiological score; SOFA, sequential organ failure assessment.
