Radiation exposure trauma

Raquel M Schears, Zainab Farzal, Zehra Farzal, Anne C Fischer
BACKGROUND: The actual baseline of radiation exposure used in evaluating pediatric trauma is not known and has relied on estimates in the literature that may not reflect clinical reality. Our objectives were to determine the baseline amount of radiation delivered in a pediatric trauma evaluation and correlate radiation exposure with trauma activation status to identify the cohort most at risk. METHODS: We retrospectively evaluated trauma patients (N = 1050) at an independent Level I children's hospital for each level of trauma activation (consults, alerts, stats) from June 2010 to January 2011...

BACKGROUND AND PURPOSE: In blunt traumatic brain injury with isolated falcotentorial subdural hematoma not amenable to neurosurgical intervention, the routinely performed, nonvalidated practice of serial head CT scans frequently necessitates increased hospital resources and exposure to ionizing radiation. The study goal was to evaluate clinical and imaging features of isolated falcotentorial subdural hematoma at presentation and short-term follow-up. MATERIALS AND METHODS: We performed a retrospective analysis of patients presenting to a level 1 trauma center from January 2013 to March 2015 undergoing initial and short-term follow-up CT with initial findings positive for isolated subdural hematoma along the falx and/or tentorium...

The robot-assisted catheter system can increase operating distance thus preventing the exposure radiation of the surgeon to X-ray for endovascular catheterization. However, few designs have considered the collision protection between the catheter tip and the vessel wall. This paper presents a novel catheter operating system based on tissue protection to prevent vessel puncture caused by collision. The integrated haptic interface not only allows the operator to feel the real force feedback, but also combines with the newly proposed collision protection mechanism (CPM) to mitigate the collision trauma...

INTRODUCTION: Blunt chest trauma in children is common. Although rare, associated major thoracic vascular injuries (TVIs) are lethal potential sequelae of these mechanisms. The preferred study for definitive diagnosis of TVI in stable patients is computed tomographic angiography imaging of the chest. This imaging modality is, however, associated with high doses of ionizing radiation that represent significant carcinogenic risk for pediatric patients. The aim of the present investigation was to define the incidence of TVI among blunt pediatric trauma patients in an effort to better elucidate the usefulness of computed tomographic angiography use in this population...

INTRODUCTION: Computed tomographic (CT) imaging is widely available in Australian rural and remote hospitals and is often performed prior to patient transfer to definitive tertiary hospital care. We hypothesised that critically ill trauma and neurosurgical patients might have CT scans repeated after interhospital transfer and that the utility of this practice might be low in relation to the additional financial cost and radiation exposure. METHODS: We conducted a retrospective review of clinical records to determine the proportion of trauma and neurosurgical patients transferred to our tertiary ICU from other hospitals between 1 June 2013 and 30 June 2014 who underwent a repeat CT scan...

BACKGROUND: Recent scientific work proved that knowledge about body composition beyond the body mass index is essential. Both adipose tissue and muscular status are determining risk factors of morbidity and mortality. Analysis of single cross-sectional computed tomography (CT) images, acquired during routine care only to prevent additional radiation exposure, provide a detailed insight into the body composition of chronically and critically ill patients. METHODS: This retrospective study included 490 trauma patients of whom a whole-body multiple detector CT scan was acquired at admission...

To avoid disturbed teamwork, unnecessary radiation exposure, and procedural delays, we designed and tested a uniform communication language for use in fluoroscopy-assisted surgical procedures. Input of surgeons and radiographers was used to create a set of commands. The potential benefit of this terminology was explored in an experimental setting. There was a tremendous diversity in the currently used terminology. Use of the newly designed terminology showed a reduction of procedural time and amount of images needed...

In childhood, the most common type of brain tumors is medulloblastoma, a highly malignant primary brain tumor that is found in the cerebellum or posterior fossa. The tumor mass increases and generates obstructive hydrocephalus. Risk factors (that might be involved in some cases) include the genetic syndrome such as type 1 neurofibromatosis, exposure to ionizing radiation and Epstein-Barr virus. Medulloblastoma is associated with recessively inherited Turcot disease and with conditions as ataxia-telangiectasia syndrome in several cases...

INTRODUCTION: The National Emergency X-Radiography Utilization Study (NEXUS) criteria have been criticized due to the presumed unreliability of the clinical exam in elderly patients. The objective of this study was to determine if the NEXUS criteria can be safely applied to this vulnerable group of patients. METHODS: 596 trauma patients over the age of 65 were enrolled in a prospectively designed study between April 1, 2015 and October 1, 2016. The study was designed to encourage the use of the NEXUS criteria for all trauma patients including the elderly...

INTRODUCTION: Lag screw cutout is one of the most commonly reported complications following intramedullary nail fixation of intertrochanteric femur fractures. However, its occurrence can be minimized by a well-positioned implant, with a short Tip-to-Apex Distance (TAD). Computer-assisted navigation systems provide surgeons with the ability to track screw placement in real-time. This could allow for improved lag screw placement and potentially reduce radiation exposure to the patient and surgeon...

Adrenal trauma is rarely encountered in the pediatric population, often as a component of multi-organ injury and often presenting with hematoma formation. Contrast-enhanced computed tomography (CECT) is the established imaging modality both for initial evaluation and follow-up of patients with blunt abdominal trauma. In children, radiation exposure should be minimized and alternative imaging strategies are needed. Contrast-enhanced ultrasound (CEUS) has recently been successfully used for evaluation of patients with hepatic, renal and splenic injury...

BACKGROUND: Ultrasound imaging can be used to diagnose fractures in patients with acute trauma. Its main advantages over conventional imaging are the absence of radiation exposure and its greater availability. METHODS: A systematic search in electronic databases (Medline, Embase, Cochrane CENTRAL) was supplemented by a manual search on the Internet and in the reference lists of pertinent publications. The QUADAS-2 instrument was used to assess the quality of the individual studies retrieved...

OBJECTIVE: To describe the technique and review the utility of bedside lung ultrasound in acute care. SUMMARY: Lung ultrasound is a useful point-of-care investigation in acute care, especially in patients with dyspnoea or haemodynamic instability. Although normal lung parenchyma is not accessible to ultrasound, distinctive artefacts arising from parietal and visceral pleura indirectly imply the presence of normal lung. As aeration of lung tissue reduces with disease process, visual assessment of several pathologic entities by ultrasound becomes possible...

Minimally Invasive Spine Surgery (MISS) procedures for the treatment of spinal pathologies have experienced exponential growth due to improved techniques and decreased trauma to the patient. Several MISS procedures that require the use of a trans-pedicular cannula as a guiding tool for pedicle screw placement, delivery of biomaterials to the vertebral body or injection of biologics to the disc space have been described. Although these are clear advantages of MISS, the limited dissection and exposure may reduce the accuracy and stability of operation and make spine surgeons rely heavily on intraoperative fluoroscopy, raising concerns over the level of radiation exposure...

OBJECTIVE: To characterize the utilization of delayed phase computed tomography (CT) imaging in blunt renal trauma and determine if the omission of delayed phase CT imaging affected clinical outcomes in children. MATERIALS AND METHODS: A prospectively collected trauma database was reviewed between 2006 and 2016 to identify patients aged ≤21 years with a diagnosis of renal injury from blunt trauma. Demographic characteristics, injury grade, Injury Severity Score, non-kidney organ injuries, radiologic studies, and clinical course were reviewed...

BACKGROUND: A 'whole body' or 'pan-scan' computed tomography (CT) imaging approach is now becoming the standard of care during the early management of adult patients with suspected severe blunt multitrauma. A number of studies have variously reported a mortality benefit or no benefit from a pan-scan approach compared to that of carrying out body region-focused CT and/or plain radiographs or a mixture of imaging modalities. However, unanswered questions still remain due to the significant heterogeneity in practice between institutions, and the limitations of published studies...
