INTRODUCTION Renewed interest in whole blood (WB) resuscitation civilians has emerged following its military use. There is a paucity of data on role where balanced component therapy (CT) the standard care. The aim this study was to assess nationwide outcomes using WB as an adjunct CT versus alone resuscitating civilian trauma patients. METHODS We analyzed (2015–2016) Trauma Quality Improvement Program. included adult (age, ≥18 years) patients presenting with hemorrhagic shock and requiring...

INTRODUCTION Angioembolization (AE) is an integral component in multidisciplinary algorithms for achieving hemostasis patients with trauma. The American College of Surgeons Committee on Trauma recommends that interventional radiologists be available within 30 minutes to perform emergent AE. However, the impact timing AE patient outcomes still not well known. We hypothesized a delay would associated increased mortality and higher blood transfusion requirements blunt intra-abdominal solid...

Studies have proposed the use of antibiotics only in cases acute uncomplicated appendicitis (AUA). However, there remains a paucity data evaluating this nonoperative approach vulnerable frail geriatric population. The aim study was to examine long-term outcomes patients with AUA treated appendectomy compared initial management (NOP).We conducted 1-year (2017) analysis Nationwide Readmissions Database and included all patients(age, ≥65 years) diagnosis AUA. Frailty assessed using five-factor...

Never-frozen liquid plasma (LQP) was found to reduce component waste, decrease health care expenses, and have a superior hemostatic profile compared with fresh frozen (FFP). Although transfusing LQP in hemorrhaging patients has become more common, its clinical effectiveness remains be explored. This study aims examine outcomes of trauma transfused thawed FFP.Adult (≥18 years) receiving early (≤4 hours) transfusions were identified the Trauma Quality Improvement Program 2017. Patients...
