In preparation for development of a clinical decision rule (CDR) to promote more efficient use of computed tomography (CT) for diagnosing orbital fractures, the authors sought to estimate the annual incidence of orbital fractures in emergency departments (EDs) and the usage of CT to make these diagnoses. The authors also sought to evaluate a mandatory electronic data collection instrument (EDCI) administered to providers to facilitate CDR data collection. ⋯ National and local data demonstrate a low yield for CT imaging in identifying orbital fractures. Data collection using a mandatory EDCI linked to computerized provider order entry can provide prospective, consecutive patient data that are needed to develop a CDR for the selective use of CT imaging in orbital trauma. Such a decision rule could increase the efficiency in diagnosing orbital fractures, thereby improving patient care, reducing radiation exposure, and decreasing costs.

Early surface cooling of burns reduces pain and depth of injury and improves healing. However, there are concerns that cooling of large burns may result in hypothermia and worsen outcomes. In contrast, controlled mild hypothermia improves outcomes after cardiac arrest and traumatic brain injury. The authors hypothesized that controlled mild hypothermia would prolong survival in a rat model of large scald burns. ⋯ Induction of brief, mild hypothermia prolongs survival and increases the survival rate in nonresuscitated rats with large scald burns.
