Does hemorrhagic shock worsen neuromuscular recovery in a porcine model of hind limb vascular injury and ischemia-reperfusion?
This study demonstrates the feasibility of combined hemorrhagic shock and extremity ischemia-reperfusion in a large-animal survival model. The presence of hemorrhagic shock compounds the effect of extremity ischemia, reducing the ischemic threshold of the limb to <3 hours. Strategies to improve functional salvage after extremity vascular injury in the setting of shock should include attempts at restoration of flow ≤60 minutes.
