Dynamic CT scan contributes minimally to the sensitivity of physical examination in the diagnosis of surgically significant penetrating zone II neck injury. Diagnosis of esophageal injuries with dynamic CT scan appears no better than esophagography. CT scan has greater sensitivity than physical examination for the diagnosis of jugular venous injuries; however, the majority of these injuries do not require identification or surgical intervention.
Abdominal stab wound patients that are hemodynamically stable can be safely sent home from the emergency room when DPL counts are less than 1000 RBCs/mm3. Observation of hemodynamically stable patients allows for low laparotomy rates with minimal morbidity.
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.
