OBJECTIVE Dexmedetomidine (DEX) may provide a sedation level that enables sleep and communication, with less amnesia and pain medication requirements, during mechanical ventilation. Our study directly assessed patient-perceived satisfaction with coronary artery bypass graft surgery after administration of DEX or propofol for intensive care unit (ICU)(More)
BACKGROUND The Glasgow Coma Scale (GCS) has served as an assessment tool in head trauma and as a measure of physiologic derangement in outcome models (e.g., TRISS and Acute Physiology and Chronic Health Evaluation), but it has not been rigorously examined as a predictor of outcome. METHODS Using a large trauma data set (National Trauma Data Bank, N =(More)
OBJECTIVE The purpose of this study is to evaluate the utility and feasibility of abdominal ultrasound (US) in blunt trauma patients. DESIGN This prospective study examined the operational issues and the diagnostic accuracy of US in selected blunt trauma patients triaged to a Level 1 trauma center. MATERIALS AND METHODS All patients were evaluated by an(More)
HYPOTHESIS Complications are common in hospitalized surgical patients. Provider error contributes to a significant proportion of these complications. DESIGN Surgical patients were concurrently observed for the development of explicit complications. All complications were reviewed by the attending surgeon and other members of the service and evaluated for(More)
BACKGROUND Existing shock models do not address the patient with massive hemorrhage (> 1 blood volume). Such patients often die from irreversible shock. This model simulates the clinical scenario of massive hemorrhage and resuscitation (MHR) to determine if irreversible shock can be reversed. METHODS Lewis rats were bled at a rate of 1 estimated blood(More)
BACKGROUND Urban geriatric trauma patients are known to die more often than their younger counterparts. Little is known of the fate of geriatric trauma patients in a rural environment where delays to definitive treatment are frequent. We hypothesized that rural trauma patients would do worse than their urban counterparts because of prolonged delays to(More)
BACKGROUND Previous models comparing normal saline (NS) with lactated Ringer's solution (LR) for resuscitation use only mild or moderate hemorrhage and do not address the clinical situation of massive hemorrhage and resuscitation (MHR). This work compares NS and LR by using a new rat model of MHR. METHODS NS and LR were compared by using both a(More)
BACKGROUND TRISS has reigned as the preeminent trauma outcome prediction model for 20 years. Despite this endorsement, the calibration of TRISS has been poor in most data sets where it has been examined. We hypothesized that the lack of calibration of TRISS was because of the inappropriate mathematical specification of the model that TRISS is based on,(More)
The diagnosis of blunt cardiac injury in traumatized patients is problematic and the implications of such a diagnosis are not clear. Although cardiac selective creatine kinase (CK-MB) assays and electrocardiograms (EKG) are the most widely available laboratory investigations, they often correlate poorly with diagnoses made on clinical grounds, or by other(More)
Critically ill patients routinely receive H2 antagonists for stress ulcer prophylaxis while at risk for gastrointestinal bleeding. In these patients it is often difficult to assess accurately the cause of adverse effects such as thrombocytopenia. We evaluate the literature to better define thrombocytopenia related to H2 antagonist administration and discuss(More)
