Shock on arrival and the Revised Trauma Score are useful predictors of mortality and transfusion requirements, Injury Severity Score, and Abbreviated Injury Scores for the head and neck, face, chest, abdomen, and extremities. In addition, the Revised Trauma Score predicts the use of pelvic arteriography and later complications. Age predicted transfusion requirement, Injury Severity Score, the chest and skin Abbreviated Injury Scores, use of arteriography, and death.
Three-dimensional sonographic measurements of the common bile duct correlate highly with two-dimensional measurements, validating the use of three-dimensional sonography as a reliable method for evaluation of common bile duct size.
Helical CT has a sensitivity and negative predictive value equivalent to that of aortography. Using CT to eliminate the possibility of mediastinal hematoma and to evaluate the cause of an abnormal aortic contour in a trauma patient allows us to use aortography more selectively. Avoiding the performance of unnecessary aortography will expedite patient care and reduce costs. We report the results of our experience with CT and how our center successfully made this transition in the initial examination of patients with serious thoracic trauma.
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.
