1. The best predictors for the development of significant electrocardiographic changes are an admission ECG abnormality and an elevated serum troponin T level. 2. Both tests have high specificity with low to moderate sensitivity. 3. Patients with normal ECGs may develop clinically significant events. 4. CPK-MB and echocardiograms continue to be poor predictors of significant electrocardiographic events.
A rare case of blunt chest trauma resulting in internal mammary artery hemorrhage and cardiac tamponade is presented. Thoracotomy revealed anterior mediastinal hemorrhage but no pericardial hematoma. The significance of chest wall vessel hemorrhage as a cause of widened mediastinum is reiterated. The importance of accurate angiographic assessment and vigilant care of victims of blunt chest trauma who present with a widened mediastinum is emphasized.
Airbags have been shown to save lives and reduce head, neck, and upper torso trauma associated with motor vehicle crashes. However, airbags have also been implicated as the source of facial and orbital injury. We report the case of a patient who suffered bilateral lenticular subluxation, anterior chamber hemorrhages, and minor facial lacerations as the result of airbag deployment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
