Abstract Background Changes in Doppler flow patterns of hepatic veins (HV), portal vein (PV) and intra-renal (RV) reflect right atrial pressure venous congestion; the feasibility obtaining these assessments clinical relevance findings is unknown a general ICU population. This study compares morphology HV, PV RV waveform abnormalities prediction major adverse kidney events at 30 days (MAKE30) critically ill patients. Study design methods We conducted prospective observational enrolling adult...
Abstract Augmented and virtual reality devices are being actively investigated implemented for a wide range of medical uses. However, significant gaps in the evaluation these applications hinder their regulatory evaluation. Addressing is critical to demonstrating devices’ safety effectiveness. We outline key technical clinical challenges discussed during US Food Drug Administration’s public workshop, “Medical Extended Reality: Toward Best Evaluation Practices Virtual Reality Medicine” future...
Background: A transthoracic focused rapid echocardiographic evaluation (FREE) was developed to answer specific questions about treatment direction regarding the use of fluid versus ionotropes in trauma patients. Our objective evaluate clinical utility information obtained by this diagnostic test. Methods: The FREE performed an ultrasonographer or intensivist and interpreted a surgical using full service portable echo machine (Vivid i; GE Healthcare). team ordering examination surveyed before...
Abstract Immersive virtual reality (VR) consists of immersion in artificial environments through the use real-time render technologies and latest generation devices. The users feel just as immersed they would an everyday life situation, this sense presence seems to have therapeutic potentials. However, VR mechanisms remain only partially known. This study is novel that, for first time research, appropriate controls contexts, immersive characteristics (ie, control VR), multifaceted objective...
Corticosteroids are part of the treatment guidelines for COVID-19 and have been shown to improve mortality. However, impact corticosteroids on development secondary infection in is unknown. We sought define rate critically ill patients with determine effect corticosteroid use mortality COVID-19.One hundred thirty-five admitted Intensive Care Unit (ICU) at University Maryland Medical Center were included this single-center retrospective analysis. Demographics, symptoms, culture data, directed...
Limited therapies exist for patients with congenital heart disease (CHD) who develop right ventricular (RV) dysfunction. Bone marrow-derived mesenchymal stem cells (MSCs) have not been evaluated in a preclinical model of pressure overload, which simulates the pathophysiology relevant to many forms CHD. A neonatal swine RV overload was utilized test hypothesis that MSCs preserve function and attenuate remodeling. Immunosuppressed Yorkshire underwent pulmonary artery banding induce After 30...
BACKGROUND: Focused rapid echocardiographic evaluation (FREE) is a comprehensive transthoracic echocardiogram tailored for the intensive care unit. It assesses both cardiac index (CI) and left ventricular ejection fraction (EF). FREE vascular catheter-derived CI was compared, ability of to detect moderate severe dysfunction (EF <40%) determined. METHODS: quality assurance database reviewed identify patients who had hemodynamic catheter. RESULTS: Of 507 FREEs, 115 were identified, 25...
Virtual reality (VR) holds great potential in education that has not been actualized surgical training programs; much of the research into medical applications VR have management and decision making rather than procedural training. This pilot study assessed feasibility virtual educational (VR-SET) open trauma surgery procedures compared to person cadaver-based (CBT). In traditional settings multiple trainees share a cadaver, often due logistical fiscal limitations precluding routine...
BACKGROUND The association of alcohol use with in-hospital trauma deaths remains unclear. This study identifies the blood content (BAC) death accounting for injury severity and mechanism. METHODS involves a historical cohort 46,222 admissions to statewide center between January 1, 2002, October 31, 2011. Blood was evaluated as an ordinal variable: 1 mg/dL 100 moderate alcohol, 101 230 high greater than very alcohol. RESULTS recorded in 44,502 patients (96.3%). Moderate associated increased...
In this study, we hypothesized that immersive virtual reality (VR) environments may reduce pain in patients with acute traumatic injuries, including brain injuries. We performed a randomized within-subject study hospitalized injury moderate (numeric score ≥3 of 10). compared 3 conditions: (1) an VR environment (VR Blu), (2) content control the identical delivered through nonimmersive tablet computer (Tablet and (3) second composed donning headgear without to for placebo effects sensory...
Objectives: To determine whether comprehensive quantitative echocardiogram could be used as a resuscitation tool in critically ill surgical patients and to assess its effect on patient care. Design: Prospective observational. Setting: The Trauma Surgical Intensive Care Units of the University Maryland Medical Center. Patients: Critically trauma patients. Interventions: Focused Rapid Echocardiographic Evaluation (FREE), an abbreviated version transthoracic echocardiogram, which is under...
Identification of occult hypovolemia in trauma patients is difficult. We hypothesized that acute patients, the response ultrasound-measured minimum inferior vena cava diameter (IVCDMIN), IVC Collapsibility Index (IVCCI), internal jugular (IJVDMIN) or IJV (IJVCI) after up to 1 hour fluid resuscitation would predict 24-hour intravenous requirements (24FR).An NTI-funded, American Association for Surgery Trauma Multi-Institutional Trials Committee prospective, cohort trial was conducted at four...
Objectives: Missed pancreatic injury carries significant morbidity. Computerized tomography (CT) imaging is useful, but may lack sensitivity to identify injury. New-generation CT scanners should improve sensitivity, this has not been studied. A previous study published in 2002 evaluating the for identifying with single-slice yielded a 68% correlation between operative and findings. We aim accuracy of modern diagnosis grading Methods: All trauma admissions from 2008 2012 were retrospectively...
