Sixteen cases of gross fresh PCA muscle hemorrhages were collected from a series of 1500 medicolegal autopsies consecutively performed by the authors, an incidence of about 1%. These hemorrhages occurred in cases of deaths resulting from a variety of causes, including natural disease, physical agents and drugs. In none of the cases was there any evidence of external trauma to the neck. In two cases endotracheal intubation had been performed; however, the lack of injury to the tissues between the tube and the muscles probably rules this factor out. In over 50% of the cases, PCA muscle hemorrhages were found in association with "asphyxial" petechial hemorrhages. A consideration of our findings and a study of the literature points out that before considering any individual case of PCA muscle hemorrhages as resulting from direct trauma, additional evidence is needed.
作者在连续进行的1500例法医尸检中收集到16例明显的新鲜PCA肌肉出血病例，发生率约为1%。这些出血发生在因多种原因导致的死亡病例中，包括自然疾病、物理因素和药物。所有病例均无颈部外部创伤的证据。有两例进行了气管插管；然而，插管与肌肉之间组织未受损伤可能排除了这一因素。超过50%的病例中，PCA肌肉出血与“窒息性”瘀点出血有关。对我们的研究结果进行考量并查阅文献后指出，在将任何一例PCA肌肉出血视为直接创伤所致之前，还需要更多证据。
