Emergency department thoracotomy (EDT) is a procedure used in an attempt to save lives of patients in extremis. This study aims to determine predictors of survival and futility by proposing a scoring scale that measures cardiac instability and its use in predicting survival of victims of penetrating trauma undergoing EDT.
This retrospective study analyzes patients who underwent EDT during a 45-month period at Howard University Hospital, Washington, DC. Vital signs and Glasgow Coma scale (GCS) scores were analyzed at the scene and in the emergency department. A cardiac instability score (CIS) was devised to assign values to vital signs, and the GCS was based on scores from the emergency department.
Emergency department vital signs, female gender, absence of cardiopulmonary resuscitation (CPR), and high CIS were found to be statistically significant predictors of survival.
The CIS correlated with survival of patients who underwent EDT and was found to be statistically significant in determining the outcome of an EDT.
急诊开胸术（EDT）是一种用于挽救生命垂危患者的手术。本研究旨在通过提出一种衡量心脏不稳定程度的评分量表，并将其用于预测接受 EDT 的穿透性创伤患者的生存情况，来确定生存和无效的预测因素。
本回顾性研究分析了在华盛顿特区霍华德大学医院进行 EDT 的 45 个月期间的患者。在现场和急诊室分析生命体征和格拉斯哥昏迷评分（GCS）。设计了一个心脏不稳定评分（CIS）来为生命体征赋值，GCS 基于急诊科的评分。
急诊室生命体征、女性、无心肺复苏（CPR）和高 CIS 被发现是生存的统计学显著预测因素。
CIS 与接受 EDT 的患者的生存相关，并且在确定 EDT 的结果方面具有统计学意义。
