Abstract/OtherAbstract:
INTRODUCTION: Unavailability of blood (and oxygen delivery) for pre-hospital resuscitation in haemorrhagic shock patients are major problems, supporting the importance for novel resuscitation strategies. In a combined polytrauma model of uncontrolled haemorrhage and traumatic brain injury (TBI) in swine, we investigated if pre-hospital administration of the haemoglobin based oxygen carrier HBOC-201 will improve tissue oxygenation and physiologic parameters compared to Lactated Ringer's (LR) solution.
MATERIALS AND METHODS: Anaesthetised Yorkshire swine underwent fluid-percussion TBI and Grade III liver laceration. During a 30-min pre-hospital phase, the animals were resuscitated with a single infusion of HBOC-201, LR solution, or nothing (NON). Upon hospital arrival, the animals were given blood or normal saline as needed. Surviving animals were euthanised 6h post-injury. Cerebral blood flow was measured by microsphere injection, and pathology was assessed by gross observation and immunohistochemical analysis.
RESULTS: Mean TBI force (2.4±0.1atm) (means±standard error of the mean) and blood loss (22.5±1.7mL/kg) were similar between groups. Survival at the 6h endpoint was similar in all groups (∼50%). Cerebral perfusion pressure (CPP) and brain tissue oxygen tension were significantly greater in HBOC-201 as compared with LR animals (p<0.005). Mean arterial pressure (MAP) and mean pulmonary artery pressure (MPAP) were not significantly different amongst groups. Blood transfusion requirements were delayed in HBOC-201 animals. Animals treated with HBOC-201 or LR showed no immunohistopathological differences in glial fibrillary acidic protein (GFAP) and microtubule-associated protein 2 (MAP-2). Severity of subarachnoid and intraparenchymal haemorrhages were similar for HBOC and LR groups.
CONCLUSION: In this polytrauma swine model of uncontrolled haemorrhage and TBI with a 30-min delay to hospital arrival, pre-hospital resuscitation with one bolus of HBOC-201 indicated short term benefits in systemic and cerebrovascular physiological parameters. True clinical benefits of this strategy need to be confirmed on TBI and haemorrhagic shock patients.
