Management of poly-trauma patients presenting to the emergency room is usually a challenging and formidable task. Two of the common problems seen in those patients are shock and neurological dysfunction. A huge differential for post-traumatic circulatory collapse exist and timely identification of the etiology is of utmost importance to avoid complications. In this report we are describing 2 cases presenting with circulatory collapse following trauma. The first case was a 29 year old female who presented after a motor vehicle accident fully conscious with severe hypotension and bradycardia. The second case presented with severe hemodynamic instability after falling at home. Physical examination of both patients revealed weakness in all 4 limbs and CT cervical spine revealed complete anterior sublaxation of C5 over C6 cervical vertebrae in the first case and partial sublaxation of C5 over C6 cervical vertebrae in the second case confirming that spinal cord injury is the likely cause for these hemodynamic alterations. A high index of suspicion for spinal cord injuries is therefore mandatory when managing a trauma patient presenting with quadriparesis and hemodynamic instability that is otherwise unexplained especially when the ensuing hypotension is associated with bradycardia instead of reflex tachycardia. Awareness of this cause of circulatory collapse is particularly important in the unconscious patient where eliciting sensory and motor deficits looking for spinal cord injury is not always feasible. Both patients were transferred to the intensive care unit and were maintained on epinephrine till becoming hemodynamically stable. The report aims to sensitize readers to this cause of post-traumatic circulatory collapse.
