A method of quantifying the anatomic extent of injury to the heart, Penetrating Cardiac Trauma Index, (PCTI) and other thoracic organs has been proposed. The total extent of thoracic injury, Penetrating Thoracic Trauma Index (PTTI), was measured. When associated abdominal injury was present, it was assessed by the Penetrating Abdominal Trauma Index (PATI) of Moore et al. The severity of total injury sustained by the patient, represented by the Penetrating Trauma Index (PTI), was determined by the sum total of these scores. The extent of physiologic abnormality induced by cardiac penetration, (Physiologic Index or PI), was graded on a scale of increasing severity from 5-20 based on the vital signs of patients on admission. Analysis of 112 patients with penetrating cardiac injuries (1973-1983) revealed that the indices, PCTI and PI, showed an excellent correlation with survival (R2 = 0.827 and 0.928, respectively) as did the total extent of trauma (PTI). A composite prognostic score of the sum of PI and PTI demonstrated a significant separation of survivors from nonsurvivors (p less than 0.001). It is concluded that these anatomic (PCTI and PTI) and physiologic (PI) indices are valid and, with additional confirmation, may provide an objective method of evaluating penetrating cardiac injuries.
已经提出了一种量化心脏、穿透性心脏创伤指数（PCTI）及其他胸部器官损伤解剖范围的方法。测量了胸部损伤的总范围，即穿透性胸部创伤指数（PTTI）。当存在相关腹部损伤时，通过摩尔等人的穿透性腹部创伤指数（PATI）进行评估。患者所遭受的总损伤严重程度，以穿透性创伤指数（PTI）表示，由这些分数的总和确定。根据入院时患者的生命体征，将心脏穿透引起的生理异常程度（生理指数或PI）从5到20按严重程度递增进行分级。对112例穿透性心脏损伤患者（1973 - 1983年）的分析表明，指数PCTI和PI与生存率显示出极好的相关性（分别为R2 = 0.827和0.928），创伤总范围（PTI）也是如此。PI和PTI总和的综合预后评分显示存活者与非存活者有显著差异（p小于0.001）。结论是，这些解剖学（PCTI和PTI）和生理学（PI）指数是有效的，经过进一步证实后，可能提供一种评估穿透性心脏损伤的客观方法。
