Background: To compare haemodynamic and cerebral variables during aggressive fluid resuscitation vs. administration of a hypertonic starch solution (HS) combined with either noradrenaline [norepinephrine] or arginine vasopressin in an animal model of uncontrolled haemorrhagic shock. Methods: After Animal Investigational Committee approval, 24 anaesthetised pigs Underwent a liver trauma. At haemodynamic decompensation, animals were randomly assigned to receive fluid resuscitation (6% HES 130/0.4, 20 mL/kg, and Ringer, 40 mL/kg: FIR group, n = 8), or noradrenaline (bolus 20 mu g/kg, continuously 1 mu g/kg/min) combined with HS (7.2% NaCl/6% HES 200/0.5:4 mL/kg) (n = 8 NA/HS group), or vasopressin (bolus 0.2 U/kg, continuously 0.04 U/kg/min) combined with HS (4 mL/kg) (n = 8: AVP/HS group), respectively. Thirty minutes after drug administration, bleeding was controlled manually. Results: Mean arterial blood pressure (MAP), cerebral perfusion pressure (CPP), and brain tissue oxygen pressure (PbtO2) decreased significantly with haemorrhage in all groups (p < 0.05). AVP/HS resulted in a faster and higher increase of MAP and CPP compared to both NA/HS and FR (p < 0.001 vs. FR; p < 0.01 vs. NA/HS). Compared to FR, PbtO2 increased faster with AVP/HS and NA/HS (p < 0.05) after therapy, and ICP was lower at the end of the Study period (p < 0.05). All animals (8/8) of the AVP/HS group survived, compared to 4/8 and 4/8 in the NA/HS and FR group, respectively (p = 0.07). Conclusions: Following uncontrolled haernorrhagic shock in this animal model, combination of HS With arginine vasopressin increased CPP and cerebral oxygenation faster than aggressive fluid resuscitation, without re-increasing ICP.
