Predictors for survival of penetrating trauma using emergency department thoracotomy in an urban trauma center: the Cardiac Instability Score.
BACKGROUND: 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.
METHODS: 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.
RESULTS: Emergency department vital signs, female gender, absence of cardiopulmonary resuscitation (CPR), and high CIS were found to be statistically significant predictors of survival.
CONCLUSIONS: The CIS correlated with survival of patients who underwent EDT and was found to be statistically significant in determining the outcome of an EDT.
