Table 4 Differences in potential physiological triggers in RBC-transfused patients 0-2 hours prior to transfusion depending on cardiovascular disease or bleeding

From: Red blood cell transfusion in septic shock - clinical characteristics and outcome of unselected patients in a prospective, multicentre cohort

  Differences, bleeding vs. non-bleeding Standard error P value
Haemoglobin (g/dl) 0.2 0.1 0.19
pH -0.03 0.01 0.04
PaO2/FiO2 (kPa) -5.4 1.5 0.0003
ScvO2 (%) -5.2 3.3 0.12
Lactate (max) (mmol/l) 1.5 0.4 0.0005
MAP (min) (mmHg) -2 2 0.19
Heart rate (max) (beats/min) -3 3 0.38
  Differences, CVD vs. no CVD Standard error P value
Haemoglobin (g/dl) 0.4 0.2 0.048
pH 0 0.02 0.90
PaO2/FiO2 -3.6 2.1 0.10
ScvO2 (%) -2.7 3.3 0.43
Lactate (max) (mmol/l) -0.7 0.4 0.23
MAP (min) (mmHg) 0 2 0.98
Heart rate (max) (beats/min) -4 5 0.40
  1. CVD, cardiovascular disease; MAP, max, maximum; mean arterial pressure; min, minimum; ScvO2, central venous oxygen saturation.
