<h3>Importance</h3> Describing the changes in trauma volume and injury patterns during course of coronavirus disease 2019 (COVID-19) pandemic could help to inform policy development hospital resource planning. <h3>Objective</h3> To examine trends admissions throughout Los Angeles County (LAC) pandemic. <h3>Design, Setting, Participants</h3> In this cohort study, all 15 verified level 1 2 centers LAC from January June 7, 2020 were reviewed. All same period used as historical control. For...
Computed tomography (CT) imaging of hemodynamically abnormal trauma patients undergoing aggressive resuscitation is controversial. Our study investigated outcomes for thoracoabdominal CT prior to definitive therapy. Hemodynamically (HR≥120 bpm, SBP<90 mmHg) arriving our Level I center between 2015 and 2022 were reviewed. Patients with achieving hemodynamic improvement (SBP≥90 included. Pediatric patients, pregnant traumatic arrests excluded. After matching baseline characteristics, findings,...
Prehospital blood transfusions result in a significant reduction mortality risk for injured patients hemorrhagic shock; however, prehospital have not been widely implemented across the United States. Thus, paucity of data surrounding impact achieving near-complete population-level access to this resource exists. We aimed determine number lives that could potentially saved among shock between 2020 and 2023 had products (blood components or whole blood, pBP) fully implemented. performed...
Recent trends in prehospital tourniquet use remain underreported. In addition, the impact of on patient survival has not been evaluated a population-level study. We hypothesized that tourniquets were used more frequently Los Angeles County and their was associated with improved survival.This is retrospective cohort study using database maintained by Emergency Medical Services Agency. included patients who sustained extremity vascular injuries between October 2015 July 2019. Patients divided...
BACKGROUND Leak following surgical repair of traumatic duodenal injuries results in prolonged hospitalization and oftentimes nil per os treatment. Parenteral nutrition (PN) has known morbidity; however, leak patients often have complex hospital courses resulting barriers to enteral (EN). We hypothesized that EN alone would be associated with (1) shorter duration until closure (2) less infectious complications length stay compared PN. METHODS This was a post hoc analysis retrospective,...
BACKGROUND Duodenal leak is a feared complication of repair, and innovative complex repairs with adjunctive measures (CRAM) were developed to decrease both occurrence severity when leaks occur. Data on the association CRAM duodenal are sparse, its impact outcomes nonexistent. We hypothesized that primary repair alone (PRA) would be associated decreased rates; however, improved recovery do METHODS A retrospective, multicenter analysis from 35 Level 1 trauma centers included patients older...
Introduction: Limited options exist for cardiovascular support of the trauma patient in extremis. This population offers challenges that are often considered insurmountable. article identifies a heterogeneous group patients extremis who may benefit from extracorporeal membrane oxygenation. Methods: Data were sourced medical records all placed on oxygenation following at Level I Trauma Center between 1 December 2016 and 2017. Results: All male (N = 7), mostly with blunt injuries (n 5), an...

This cohort study examined the differences in prehospital treatment received by patients with traumatic injury belonging to different racial and ethnic groups between 2013 2020 Los Angeles County.
Albeit low survival rates, resuscitative thoracotomy (RT) is considered standard for selected trauma patients. Because it has potential rapid cardiopulmonary rescue, extracorporeal membrane oxygenation (ECMO) may augment RT. The aim of this study was to identify the impact ECMO on patients that recently underwent RT after injury.All who were identified from National Trauma Data Bank (2007-2017). Patients excluded if they died within 60 minutes, delayed ECMO, and/or had missing data. Delayed...
For trauma patients with noncompressible truncal hemorrhage (NCTH), aortic occlusion (AO) is attempted either resuscitative thoracotomy (RT) or the endovascular balloon of aorta (REBOA). However, it often challenging to identify group who would benefit from AO procedures. We hypothesized that met simple clinical criteria have better outcomes following This a retrospective cohort study using Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery database (November 2013-August...
The utility of prehospital thoracic needle decompression (ND) for tension physiology in the civilian setting continues to be debated. We attempted provide objective evidence clinical improvement when ND is performed and determine whether technical success associated with provider factors. also certain scenarios are more predictive than others successful symptoms performed.Prehospital data acquired from one air ambulance service serving 79 trauma centers consisted 143 patients (n = 143;...

Background: The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) has been proposed as a diagnostic tool necrotizing soft tissue infection (NSTI). However, its utility remains underreported, particularly in patients with comorbid conditions. purpose of this study was to identify the test characteristics LRINEC various Patients and Methods: We conducted retrospective including suspected NSTI. Our were then relegated into subgroups; intravenous drug use (IVDU), end-stage liver...
Abstract Annular pancreas is a rare congenital abnormality that often considered neonatal condition, though in few cases it can present adulthood. Patients diagnosed with annular adulthood are asymptomatic and incidentally from radiologic studies. While there no existing treatment protocol for symptomatic pancreas, multiple surgical approaches have been documented the literature. In this case study we 49-year-old female patient who presented gastric outlet obstruction secondary to pancreas....
Abstract Gastric surgery may result in internal herniation of bowel, weeks to years after the initial and can rapid onset death if not promptly treated. We present a case which patient with this complication underwent despite his clear refusal surgery. The had remote history gastrectomy for malignancy. Several later, he presented feared an local hospital. surgeon recommended urgent operation correct this. However, refused. When became comatose, performed surgery, but patient’s condition...
Introduction Gang-related tattoos may increase an individual’s risk for violent victimization. We present our early experience using a physician-staffed tattoo removal initiative as 1 component of violence prevention program. Methods Surgeons from trauma department in partnership with community advocacy group performed voluntary laser individuals within catchment area. Clients were asked to complete voluntary, anonymous survey. This survey addressed acquisition, identified motives and goals...
