Accidents in which a person is run over are often associated with multiple serious injuries. Immediate bleeding control is crucial. Pressure and shear stress at the borders of subcutaneous tissue to the muscle fascia can cause hypoperfusion and the emergence of blood-filled cavities that are associated with a high risk of infection and necrosis, a so-called Morel-Lavallée lesion. Insufficient therapy can lead to local complications and furthermore to live-threatening sepsis.
行人被碾压的事故通常会伴有多处重伤。立即控制出血至关重要。皮下组织与肌肉筋膜交界处的压力和剪切力会导致灌注不足以及充满血液的腔隙出现，这些腔隙与感染和坏死的高风险相关，即所谓的莫雷尔-拉瓦利埃损伤。治疗不足会导致局部并发症，进而引发危及生命的败血症。
