Patients who have suffered blunt trauma and present in shock of uncertain cause represent a problem frequently encountered by emergency physicians. A retrospective review of the charts of 879 patients who had suffered blunt trauma and presented to a regional trauma unit over a 44-month period revealed that 154 of the patients had presented to either a hospital or the trauma unit in shock. The most common causes of shock when a single source of hemorrhage was identified were, in order of decreasing frequency, intraperitoneal hemorrhage, pelvic or other musculoskeletal fractures, thoracic hemorrhage, severe head injury and spinal cord injury. Severe head injuries accounted for only 8% of the single-source cases and contributed to shock in only seven of the remaining cases.
遭受钝性创伤并出现原因不明休克的患者是急诊医生经常遇到的问题。一项对879例在44个月期间遭受钝性创伤并被送至某地区创伤中心的患者病历的回顾性研究显示，其中154例患者在休克状态下被送至医院或创伤中心。当确定单一出血源时，休克最常见的原因按频率递减顺序依次为腹腔内出血、骨盆或其他肌肉骨骼骨折、胸腔出血、严重颅脑损伤和脊髓损伤。严重颅脑损伤仅占单一出血源病例的8%，并且仅在其余病例中的7例中导致休克。
