ΔPO 2 between cortical and medullary microvascular PO 2 calculated as a measure of oxygen redistribution. Cortical microvascular PO2 (cμPO2) and medullary microvascular PO2 (mμPO2) are shown for baseline (t0), endotoxemia (t1) and resuscitation (t2) in (a) control (C) group (n = 5), (b) nonresuscitation (NR) group (n = 8), (c) HES130/0.4 resuscitation group (n = 8), (d) HES200/0.5 resuscitation group (n = 8) and (e) Ringer's lactate (RL) resuscitation group (n = 8). *P < 0.05 versus baseline, #P < 0.05 versus control group, •P < 0.05 versus NR group. Data presented as mean ± standard deviation. μPO2, microvascular PO2. ΔPO2, the difference in cμPO2 and mμPO2.
