Does the incidence of thoracic aortic injury warrant the routine use of chest computed tomography in children?

CT in pediatric trauma patients

The decision as to whether to perform a computed tomography (CT) examination in severe pediatric trauma poses a challenge. The therapeutic benefit of computed tomography in injured children is lower compared to adults, while the potential negative effects of ionizing radiation may be higher. Thus, the threshold for CT should be higher. Centers that less frequently treat pediatric cases tend to conduct more whole-body CT examinations than dedicated pediatric trauma centers, indicating a clinical overestimation of injury severity with subsequently unnecessary imaging due to inexperience. On the other hand, a CT scan that is not performed but is actually necessary can also have negative consequences if an injury is detected with a delay. An injured child presents a challenging situation for all involved healthcare providers, and thus requires a structured approach to decision-making.Selective literature review of the benefits and risks of CT in injured children, as well as indications for whole-body and region-specific CT imaging.This article provides an overview of current guidelines, recent insight into radiation protection and the benefits of CT in injured children, and evidence-based decision criteria for choosing the appropriate modality based on the mechanism of injury and the affected body region. · Whole-body CT has less of an influence on treatment decisions and mortality in severely injured children than in adults.. · For radiation protection reasons, the indication should be determined more conservatively in children than in adult trauma patients.. · The indication for CT should ideally be determined separately for each region of the body.. · Ultrasound and MRI are a good alternative for the primary diagnostic workup in many situations.. · Appelhaus S, Schönberg SO, Weis M.

Optimizing Advanced Imaging of the Pediatric Patient in the Emergency Department: Technical Report

Advanced diagnostic imaging modalities, including ultrasonography, computed tomography, and magnetic resonance imaging, are key components in the evaluation and management of pediatric patients presenting to the emergency department. Advances in imaging technology have led to the availability of faster and more accurate tools to improve patient care. Notwithstanding these advances, it is important for physicians, physician assistants, and nurse practitioners to understand the risks and limitations associated with advanced imaging in children and to limit imaging studies that are considered low value, when possible. This technical report provides a summary of imaging strategies for specific conditions where advanced imaging is commonly considered in the emergency department. As an accompaniment to the policy statement, this document provides resources and strategies to optimize advanced imaging, including clinical decision support mechanisms, teleradiology, shared decision-making, and rationale for deferred imaging for patients who will be transferred for definitive care.

Application of a Thoracic CT Decision Rule in the Evaluation of Injured Children: A Quality Improvement Initiative

BACKGROUND

Differences in injury patterns in children suggest that life-threatening chest injuries are rare. Radiation exposure from computed tomography increases cancer risk in children. Two large retrospective pediatric studies have demonstrated that thoracic computed tomography can be reserved for patients based on mechanism of injury and abnormal findings on chest radiography.

OBJECTIVE

Implement a decision rule to guide utilization of thoracic computed tomography in the evaluation of pediatric blunt trauma, limiting risk of unnecessary radiation exposure and clinically significant missed injuries.

METHODS

A protocol for thoracic computed tomography utilization in pediatric blunt trauma was implemented using a Plan-Do-Study-Act cycle at our Level I pediatric trauma center, reserving thoracic computed tomography for patients with (1) mediastinal widening on chest radiography or (2) vehicle-related mechanism and abnormal chest radiography. We modified our resuscitation order set to limit default imaging bundles. The medical record and trauma registry data were reviewed for all pediatric blunt trauma patients (younger than 18 years) over a 30-month study period before and after protocol implementation (May 2017 to July 2018 and February 2019 to April 2020), allowing for a 6-month implementation period (August 2018 to January 2019).

RESULTS

During the study period, 1,056 blunt trauma patients were evaluated with a median (range) Injury Severity Score of 5 (0-58). There were no significant demographic differences between patients before and after protocol implementation. Thoracic computed tomography utilization significantly decreased after implementation of the protocol (26.4% [129/488] to 12.7% [72/568; p < .05]), with no increase in clinically significant missed injuries. Protocol compliance was 88%.

CONCLUSIONS

Application of decision rules can safely limit ionizing radiation in injured children. Further limitations to thoracic computed tomography utilization may be safe and warrant continued study due to the rarity of significant injuries.

Should Radiation Exposure be an Issue of Concern in Children With Multiple Trauma?

OBJECTIVE

The aims of this study were 3-fold: first, establish the level of radiation exposure experienced by the pediatric trauma patients; second, model the level of risk of developing fatal carcinogenesis; and third, test whether pattern of injury was predictive of the level of exposure.

SUMMARY BACKGROUND DATA

There are certain conditions that cause children to be exposed to increased radiation, that is, scoliosis, where level of radiation exposure is known. The extent that children are exposed to radiation in the context of multiple traumas remains unclear.

METHODS

Patients below the age of 16 years and with an Injury Severity Score (ISS) ≥10, treated by a Major Trauma Center for the period January 2008 to December 2018 were identified. The following data were extracted for the year following the patient's injury: number, doses, and type of radiological examination.The sex and age of the patient was taken into account in the calculation of the risk of developing a carcinogenesis.

RESULTS

The median radiation dose of the 425 patients identified in the 12 months following injury, through both CT and radiographs, was 24.3 mSv. Modeling the predictive value of pattern of injury and other relevant clinical values, ISS was proportionately predictive of cumulative dose received.

CONCLUSION

A proportion of younger polytrauma patients were exposed to high levels of radiation that in turn mean an increased risk of carcinogenesis. However, the ISS, age, injury pattern, and length of hospital stay are predictive of both risks, enabling monitoring and patient advisement of the risks.

[Differences in injury patterns in motorcycle accidents involving children and adolescents]

Hintergrund

Verkehrsunfälle und ihre Verletzungsfolgen stellen eine häufige traumatische Ursache für das Versterben und für das Auftreten von irreversiblen Schäden bei Kindern und Jugendlichen dar. Bei Motorradunfällen unterscheiden sich dabei Verletzungsmuster abhängig vom Patientenalter.

Ziel der Arbeit

Ziel dieser Studie ist es, die typischen Verletzungsmuster nach Motorradunfällen im Kindes- und Jugendalter vergleichend zu beschreiben, da diese einen ausschlaggebenden Einfluss auf die Prävention sowie die adäquate Behandlung der jeweiligen Patientengruppen bieten können.

Material und Methoden

In die Studie wurden innerhalb der Jahre 2002–2018 22.923 Patienten aus dem TraumaRegister der Deutschen Gesellschaft für Unfallchirurgie (DGU®) eingeschlossen. Die Auswertung erfolgte in 4 Altersgruppen: Gruppe 1 (4 bis 15 Jahre), Gruppe 2 (16 bis 17 Jahre), Gruppe 3 (18 bis 20 Jahre) sowie Gruppe 4 (21 bis 50 Jahre) als Kontrolle.

Ergebnisse

In Gruppe 2 stellten Extremitätenverletzungen das häufigste Verletzungsmuster dar und traten überwiegend im Bereich der unteren Extremität auf. Zudem ergab die Analyse, dass Gruppe 1 häufiger ein schweres Schädel-Hirn-Trauma erleidet, trotz initial schlechtem Zustand aber ein besseres Outcome aufweist. Thorakale, abdominelle sowie Wirbelsäulen- und Beckenverletzungen kommen bei den jüngeren Altersgruppen seltener vor. Insbesondere stellen Rippenfrakturen eine Rarität bei Kindern dar. In der Diagnostik werden Kinder im Vergleich zu Erwachsenen seltener einer Ganzkörper-CT-Diagnostik zugeführt.

Diskussion

Die Studie deckt altersabhängige Unterschiede in den Verletzungsmustern von Patienten auf, die als Beifahrer oder Fahrer eines Motorrades in einen Unfall involviert waren. Zudem konnten ebenso Unterschiede in der prä- und innerklinischen Versorgung herausgearbeitet werden.

Emergency Repair of an Isolated Traumatic Avulsion of the Right Main Stem Bronchus in a 7-Year-Old Girl

Introduction  Isolated tracheobronchial injury after blunt trauma of the chest is rare. Because of the high elasticity of the chest in children, they occur mainly in the pediatric population. Case Report  We report a case of a 7-year-old girl who experienced complete avulsion of the right main bronchus at the level of the carina after a horse-riding accident. The patient presented with extensive emphysema of the upper chest, neck, and face and severe respiratory distress. Endotracheal intubation led to tension pneumothorax. After insertion of two 17-mm thoracostomy tubes, pneumothorax and a massive air leak persisted. Isolated central bronchial injury was confirmed by computed tomography of the chest. Bronchoscopically guided selective intubation of the left main stem bronchus failed and the patient desaturated, requiring immediate salvage right posterolateral thoracotomy. Simultaneous occlusion of the defect, stabilization, and subsequent selective left lung intubation was possible only after placing a suture at the tracheal rim of the defect for retraction allowing compression of the defect and keeping the lumen open at the same time. Conclusion  A cluster of clinical signs with subcutaneous emphysema and refractory pneumothorax with air leak of the thoracotomy tube is indicative of bronchial injury. Endotracheal intubation should be postponed in these cases until after thoracostomy tube placement, if possible. Placing a retraction suture during repair is a maneuver that helps to occlude the defect and keep the remaining tracheobronchial lumen open at the same time to establish crucial ventilation of the contralateral lung.
