Competitive advantage gained from the use of helicopter emergency medical services (HEMS) for trauma patients: Evaluation of 1724 patients.

OBJECTIVES: The aim of the study was to analyze helicopter emergency medical service (HEMS) in comparison to EMS, in respect to patient's mortality and morbidity. DESIGN: From a cohort of traumatized patients (n = 1724) prospectively enrolled in the German trauma registry (DGU-R) at Frankfurt University Hospital from 2009 to 2013, 1646 could be analyzed for in-hospital mortality and short-term outcome (GOS) at discharge and compared between HEMS and EMS. MEASUREMENTS AND MAIN RESULTS: 129 patients (7.8%) died in the hospital. Unadjusted mortality was significantly lower in the HEMS group compared to EMS (p = 0.001). In a multiple logistic regression analysis after adjustment of variables including reanimation and age as the strongest predictors, in-hospital mortality was significantly reduced in HEMS (p = 0.014, OR = 0.21). Further predictors in the multiple logistic regression analysis were GCS > = 8 (p = 0.001), RRsys (p < 0.001), ISS at Head/Neck > = 3 (p = 0.003), and total ISS > = 9 (p < 0.001). Total rescue time and on scene time were associated with mortality (p < 0.001) but not included in the multiple logistic regression model. Without adjustment, short-term outcome (GOS) was significantly improved (p = 0.014). In a linear model, after adjusting for multiple variables including age, ISS Head/Neck > = 3, ISS Extremities > = 3, GCS > = 8, and RRsys as the strongest predictors (p < 0.001), the association remained significant (p = 0.043). Further predictors in the multiple linear regression analysis were total ISS > = 9 (p = 0.002), ISS abdomen (p = 0.001), and ISS Chest (p = 0.011). CONCLUSIONS: A significant improvement for in-hospital survival for HEMS could be demonstrated. Especially in Germany, with a high number of secondary call outs (about 44%) after EMS has already reached the traumatized patient, HEMS must be the first choice for severely injured trauma patients. Dispatch criteria for immediate alarm of HEMS are recommended under practical considerations.

Kinetic therapy in multiple trauma patients with severe thoracic trauma: a treatment option to reduce ventilator time and improve outcome.

PURPOSE: Continuous lateral rotational therapy (CLRT) has been described as a promising approach for prophylaxis and treatment of respiratory complications in critically ill patients over two decades ago. However, meta-analyses failed to demonstrate any significant benefit on outcome by CLRT, possibly due to the heterogeneity and low overall quality of available studies. METHODS: Observational trial over a 3-year period on outcome in trauma patients (Injury Severity Score, ISS ≥16) with severe thoracic injury (Abbreviated Injury Scale, AISThorax ≥3) initially treated with CLRT as standard of care. Epidemiological data, injury severity, and pattern and physiological parameters were recorded. Outcome indicators were time on mechanical ventilation, length of stay, rates of pneumonia, sepsis and acute respiratory distress syndrome, hospital mortality, and rates of re-intubation. Additionally, data are compared with the results from the TraumaRegister® of the German Trauma Society. RESULTS: Over the 3-year period 76 patients with ISS ≥16/AISThorax ≥3 received CLRT, equaling 24 % of all patients with ISS ≥16 between 18 and 80 years. Mean ISS was 35.3 (standard deviations, SD 12.2) [71.1 % male, 97.4 % blunt trauma, mean age 43.9 years (SD 18.7)]. Mean time on CLRT was 3.3 days (SD 2.2), time on mechanical ventilation 7.8 days (SD 7.1), and 9.2 % had to be re-intubated due to respiratory complications. CLRT-related complications occurred in 8.9 %. Overall 25 % of the patients developed pneumonia (VAP = 13.2 %). Despite a significantly higher ISS we observed shorter times on mechanical ventilation and intensive care unit in our collective in comparison to data published from the nationwide TraumaRegister®. CONCLUSIONS: CLRT remains a therapeutic option to reduce pulmonary complications after severe chest trauma in our center. However, a RCT is needed to study the effects of other treatment options such as early extubation and non-invasive ventilation or prone/supine positioning.

Epidemiology and outcome of penetrating injuries in a Western European urban region.

PURPOSE: Severe life-threatening injuries in Western Europe are mostly caused by blunt trauma. However, penetrating trauma might be more common in urban regions, but their characteristics have not been fully elucidated. METHODS: Retrospective analysis of data from patients admitted to our urban university level I trauma center between 2008 and 2013 with suspicion of severe multiple injuries. Collection of data was performed prospectively using a PC-supported online documentation program including epidemiological, clinical and outcome parameters. RESULTS: Out of 2095 trauma room patients admitted over the 6-year time period 194 (9.3 %) suffered from penetrating trauma. The mean Injury Severity Score (ISS) was 12.3 ± 14.1 points. In 62.4 % (n = 121) the penetrating injuries were caused by interpersonal violence or attempted suicide, 98 of these by stabbing and 23 by firearms. We observed a widespread injury pattern where mainly head, thorax and abdomen were afflicted. Subgroup analysis for self-inflicted injuries showed higher ISS (19.8 ± 21.8 points) than for blunt trauma (15.5 ± 14.6 points). In 82.5 % of all penetrating trauma a surgical treatment was performed, 43.8 % of the patients received intensive care unit treatment with mean duration of 7.4 ± 9.3 days. Immediate emergency surgical treatment had to be performed in 8.0 vs. 2.3 % in blunt trauma (p < 0.001). Infectious complications of the penetrating wounds were observed in 7.8 %. CONCLUSIONS: Specific characteristics of penetrating trauma in urban regions can be identified. Compared to nationwide data, penetrating trauma was more frequent in our collective (9.3 vs. 5.0 %), which may be due to higher crime rates in urban areas. Especially, self-inflicted penetrating trauma often results in most severe injuries.

[Current standard of care for initial management of open fractures in emergency departments : A nationwide survey in German trauma centers]. / Realität initialer Versorgung offener Frakturen in deutschen Notaufnahmen : Eine Umfrage aus der Sektion NIS der DGU.

BACKGROUND: Limiting the morbidity of open fractures requires highly specific initial treatment. In addition to a stringent surgical strategy, correct antibiotic prophylaxis seems to be associated with an improved outcome. In the current literature, the duration and type of antibiotic prophylaxis are under discussion. The aim of the study was to survey the current initial treatment regimes for open fractures in German emergency departments. MATERIAL AND METHODS: With an online-based anonymous 16-item questionnaire all 3006 members of the German Trauma Society were surveyed. A total of 585 questionnaires (19.5 %) were returned completed. This article presents a descriptive analysis of the current state of treatment. RESULTS: Mainly specialists (35 %), senior physicians (30 %) and chief physicians (17 %) answered as well as interns (8 %) and out-patient practitioners (10 %). Of the participants 65 % did not accept the classification of emergency services; however, 93 % carried out urgent or emergency surgery, 84 % started an antibiotic prophylaxis in the emergency department and 63 % used a standard operating procedure (SOP). A total of 60 % used 1 antibiotic drug, 25 % used 2 and 15 % used 3 or more substances. An antibiotic treatment for more than 3 days was performed by 60 % of participants. CONCLUSION: The early initiation of antibiotic prophylaxis seems to be the standard practice in German emergency departments as well as early surgery. Strategies to improve the communication between prehospital and in-hospital teams, as well as graded antibiotic prophylaxis depending on the severity of soft tissue damage are needed.

[Current practice in coagulation and transfusion therapy in multiple trauma patients: A German nation-wide online survey]. / Stand der Gerinnungs- und Transfusionstherapie beim Schwerverletzten : Eine deutschlandweite Online-Umfrage.

BACKGROUND: In recent years, the treatment of trauma-associated coagulopathy and bleeding has advanced enormously. The aim of this study was to assess the current practice of coagulation and transfusion management in Germany. PATIENTS AND METHODS: From October 2011 until January 2012 we conducted a survey via online-questionnaire that was sent per E-Mail to all members of the German Society for Trauma Surgery. It comprised 12 questions with respect to current treatment of coagulopathy and haemorrhage in trauma patients. RESULTS: The response rate was 145/3006 (5 %). The respondents had following specialties: 77.2 % trauma surgery 15.9 % anesthesiology, 6.9 % others. 64 % of respondents were employed by a Level 1 trauma centre, wheras 17 % worked in a local level 3 centre. The majority (94 %) claimed to treat hypothermia regularly. Only about half of the participants reported to follow a massive transfusion protocol in their institution. The potential components of these protocols were reported in varying rates, being it well-established components (e.g. FFP 78 %; Fibrinogen 75 %) or therapies with poor evidence in multiple trauma (Desmopressin 39 %, rFVIIa 47 %). Calcium was provided by only 48 % of respondents although generally recommended in all guidelines. CONCLUSION: The current study suggests that in Germany strategies and principles regarding management of trauma-associated coagulopathy are standardized only poorly. Level 1 centres appear to apply a more advanced approach, however to much variability exists with respect to the components of the transfusion protocols. The low response rate indicates that most German trauma surgeons consider coagulation and hemorrhage as "expert-topics" beyond their field of duty.

[Rotating physician in CHIR-Net. Evaluation of the curriculum]. / Als Kliniker Rotand im CHIR-Net. Evaluation des Kurrikulums.

BACKGROUND: Conduction of and participation in clinical trials is a major challenge for surgical departments especially as job performance in hospitals has increased immensely during the last few years due to economic aspects. Only 11.7 % of published clinical studies are randomized controlled trials. As more and more treatment procedures in medicine have an evidence-based design the aim must be to present randomized controlled trials with an evidence level 1 for an increasing number of surgical therapies. Since 2006 the German National Surgical Trial Network (CHIR-Net) has been established and funded by the Federal Ministry of Education and Research (BMBF) in order to promote the realization of clinical trials in surgery. Thus the basis for the execution of high quality clinical studies in surgery has been extended further. In the individual CHIR-Net centers clinical trials are planned, organized and supervised which requires extensive knowledge of prevalent international standards. Teaching them to rotating physicians is one of the tasks of CHIR-Net. Therefore, a special curriculum for physicians has been developed which is evaluated in this study. MATERIALS AND METHODS: From December 2010 to March 2011 an online survey of physicians who had previously rotated in the CHIR-Net was conducted, starting from the Surgical Regional Center (CRZ) Witten-Herdecke/Cologne. A total of 19 partly open and partly closed questions concerning the person, training, duration of the rotation, the funding applied for and the generated scientific output were surveyed. In addition, the curriculum for physicians and rotation time was checked by means of 17 questions in an evaluation matrix. RESULTS: In this article the results of the rotating physician evaluation are presented. The satisfaction of physicians with the training during the rotation is presented as well as an analysis of how many of the submitted publications were directly supported by CHIR-Net. It was also evaluated how many rotating physicians requested funding and what the type of funding was. CONCLUSION: With the rotating physician model of CHIR-Net a working concept for the training of surgeons in clinical research and the realization of randomized surgical trials was established as a viable solution for the difficult situation of clinical research in the surgical disciplines with the double burden of research and clinical practice.

[Current treatment concepts for olecranon and prepatellar bursitis in Austria]. / Derzeitige Versorgungssituation der Bursitis olecrani und praepatellaris in Österreich.

BACKGROUND: The limited evidence available on the diagnosis and treatment of olecranon and prepatellar bursitis indicates nationally varying treatment approaches. Therefore the aim of this study was to survey the current treatment concepts of olecranon and prepatellar bursitis in Austria. MATERIAL AND METHODS: An online questionnaire comprising of demographic data, questions regarding diagnostics and differentiation between septic bursitis (SB) and non-septic bursitis (NSB) as well as two case reports for therapy appraisal were sent to members of the Austrian Society of Orthopaedics and Orthopaedic Surgery (ÖGO) and the Austrian Society of Traumatology (ÖGU). RESULTS: The overall response rates were 46 % (ÖGU)/12 % (ÖGO). Differentiation between SB and NSB was predominantly based on medical history/clinical presentation (ÖGU: 100 %/ÖGO: 84 %) and blood sampling (ÖGU: 82 %/ÖGO: 77 %). 64/36 % of surveyed members of ÖGO/OGU performed a bursal aspiration. 95/55 % of Austrian ÖGU opinion leaders favoured a surgical treatment approach in cases of SB/NSB. Conversely, ÖGO members rather favoured a conservative treatment approach (28/27 %). CONCLUSION: Significant differences were found between ÖGO and ÖGU, with the latter favouring a surgical treatment approach in cases of SB and NSB. However, the international literature argues for a conservative treatment approach. Further high quality research is needed to establish an evidence-based treatment approach.

[Why nurses fly and surgeons rotate. The surgical study network CHIR-Net]. / Warum Schwestern fliegen und Ärzte rotieren. Das chirurgische Studiennetzwerk CHIR-Net.

BACKGROUND: The German National Surgical Trial Network (CHIR-Net) which has been funded since 2006 by the Federal Ministry of Education and Research (BMBF, funding code 01GH1001A-01GH1001F, 01GH0702) is made up of eight regional surgical centers. The aim of the CHIR-Net is the design, implementation and publication of prospective, randomized, multicenter trials to support evidence-based medicine in surgery. Two main pillars of the CHIR-Net are the surgeon on rotation program and the flying study nurse program. With these two programs the surgical hospitals are supported in their trial working by educating competent investigators and the infrastructural support of flexible and mobile study nurses. METHODS: The surgeon on rotation program and the concept of the flying study nurse are presented descriptively. Furthermore, this paper provides reports of experiences of a surgeon on rotation and a flying study nurse of the CHIR-Net. Additionally, the results of an on-line evaluation of the regional surgical hospitals (belonging to the regional surgical center of the universities Witten/Herdecke and Cologne) regarding the needs and requirements of the regional surgical hospitals are presented. RESULTS: The surgeon on rotation program of the CHIR-Net offers investigators the possibility to acquire the basics of designing, developing and implementation of high quality clinical trials. In addition, their own study projects could be intensively driven forward. The flying study nurse program enables in particular non-university surgical hospitals to be supported competitively in performing their own study projects and participating in muliticenter clinical trials. The success of these two programs has been confirmed by the conducted evaluations and the presented field reports. CONCLUSION: The CHIR-Net is able to develop a high quality study culture in Germany with its surgeon on rotation and flying study nurse program. In addition to the funding period by the BMBF, the continuance of the CHIR-Net should be a primary aim of further measures.

Early analgesic treatment regimens for patients with acute abdominal pain: a nationwide survey among general surgeons.

INTRODUCTION: Early pain relief in patients with acute nontraumatic abdominal pain in emergency departments has been discussed for years. Some randomized trials have addressed this issue but conclusive data are lacking. In this study, we assessed the current treatment practice in German hospitals in order to evaluate the necessity of a further clinical trial. METHODS: An online survey containing 27 questions was sent to general and visceral surgeons at attending level using a mailing list provided by the Professional Board of German Surgeons (BDC) using a standard interview software. The questionnaire collected demographic data, current treatment policies about frequency of early analgesia, types of pain medication, and opinions about their use and effects. RESULTS: Four hundred ninety-five completed questionnaires were returned. Many surgeons were cautious about early analgesia in the emergency department. Forty-five percent of the surgeons would provide analgesia prior to diagnosis to the majority of patients. Within the departments, differing opinions existed regarding the analgesic treatment (41 %). Thirty-two percent of all the respondents knew about a false diagnosis after early analgesia. There was heterogeneity in the estimation of the impact of pain medication on masking of clinical symptoms. A randomized controlled trial would be supported by the majority of respondents. As influencing factors for withdrawing early analgesia, we found the examiner being over 40 years of age (p < 0.05), low experience with the clinical picture of acute abdominal pain (p < 0.05), high estimation of the masking of clinical findings (p < 0.001), and knowing about a false diagnosis after early analgesia (p < 0.001) to be significant. CONCLUSION: Discordance in the analgesic treatment regimens in patients with acute abdominal pain still exists in German hospitals. The topic remains subject of frequent discussions. More high quality data are needed before a clear guideline can be given for implementation in clinical routine management.

[TEAM®-G (Trauma Evaluation and Management Germany). Serves as a basis for an interdisciplinary training in the emergency room]. / TEAM®-G ("Trauma Evaluation and Management Germany"). Grundlage für ein interdisziplinäres und interprofessionelles Schockraumtraining.

BACKGROUND: The implementation of ATLS® in the daily routine of trauma management in the emergency department is a challenge. This goal cannot be reached by educating ATLS® to a few team members only. In order to enforce the implementation of ATLS® in a level I trauma centre, a generic in-house training was introduced in 2009 with inter-professional integration of all specialists of the trauma team. MATERIALS AND METHODS: The TEAM® course (trauma evaluation and management concept of the American College of Surgeons) was the theoretical basis of the training. This educational program was developed for medical students and multidisciplinary team members. Prior training, a questionnaire for self-assessment was completed by n=84 team members to assess their knowledge about ATLS® principles. The hands-on training time was 90 min. N=10 members of the trauma team worked out three scenarios of multiple injured patients. These were provided as near-reality manikin simulations by a specialist trainer. After the training participants re-evaluated and analysed improvement by the training. Duration of trauma management and the number of missed injuries were analysed one year prior and one year after the training and served as a marker of the process and outcome quality of trauma care. RESULTS: Prior the training, 57% of trainees specified their knowledge related to the ATLS® can be improved. Their expectations were generally satisfied by the training. The mean time of trauma management in the ED could not be reduced one year after the training (36±16 min) compared to one year prior the training (39±18 min), however, the detection of missed injuries (5.6% vs. 3.2%, p<0.05) was significantly diminished after the training. CONCLUSION: Apart form education of ATLS® providers the inauguration of an interdisciplinary and interprofessionel team training may enhance implementation of ATLS- algorithms into daily routine.

A critical reappraisal of the ATLS classification of hypovolaemic shock: does it really reflect clinical reality?

AIM: The aim of this study was to validate the classification of hypovolaemic shock given by the Advanced Trauma Life Support (ATLS). METHODS: Patients derived from the TraumaRegister DGU(®) database between 2002 and 2010 were analyzed. First, patients were allocated into the four classes of hypovolaemic shock by matching the combination of heart rate (HR), systolic blood pressure (SBP) and Glasgow Coma Scale (GCS) according to ATLS. Second, patients were classified by only one parameter (HR, SBP or GCS) according to the ATLS classification and the corresponding changes of the remaining two parameters were assessed within these four groups. Analyses of demographic, injury and therapy characteristics were performed as well. RESULTS: 36,504 patients were identified for further analysis. Only 3411 patients (9.3%) could be adequately classified according to ATLS, whereas 33,093 did not match the combination of all three criteria given by ATLS. When patients were grouped by HR, there was only a slight reduction of SBP associated with tachycardia. The median GCS declined from 12 to 3. When grouped by SBP, GCS dropped from 13 to 3 while there was no relevant tachycardia observed in any group. Patients with a GCS=15 presented normotensive and with a HR of 88/min, whereas patients with a GCS<12 showed a slight reduced SBP of 117mmHg and HR was unaltered. CONCLUSION: This study indicates that the ATLS classification of hypovolaemic shock does not seem to reflect clinical reality accurately.

[Epidemiology, risk stratification and outcome of severe pediatric trauma]. / Epidemiologie, Risikostratifizierung und Behandlungsergebnisse nach schwerem kindlichen Trauma.

Accidents and trauma are the leading cause of hospital admissions and major contributors to mortality in children and adolescents. There are age-specific injury patterns and differences in the clinical presentation of pediatric trauma and treatment both at the scene and in the emergency department can be observed. In general, pediatric trauma-scores to appreciate injury severity are adapted from the adult population.The most important factor to increase mortality in the severely injured pediatric population is the extent of a concomitant traumatic brain injury (TBI). In addition, the acute trauma-associated coagulopathy, which is triggered multifactorial, is an independent prognostic marker for mortality in severe trauma. The complexity of all currently available trauma-scores for the pediatric population is one reason why these scores are not unequivocal recommended for the early use in pediatric trauma care. The pediatric BIG-Score was developed to allow an early prognostic stratification for pediatric trauma patients and includes with base excess (BE), INR (International Normalized Ratio) and GCS (Glasgow Coma Scale) relevant prognostic factors for poor outcome. Early risk stratification is crucial in pediatric trauma due to mortality rates ranging between 9% and 15% and with 50% of all fatalities to occur within the first 24 h of hospital admission.

Evaluation of current treatment regimens for prepatellar and olecranon bursitis in Switzerland.

PURPOSE: Bursitis is a common entity. However, evidence for the best treatment procedures is lacking, with management concepts varying internationally. We evaluated current treatment regimens for septic (SB) and nonseptic (NSB) prepatellar (PB) and (OB) olecranon bursitis in Switzerland and compared them to the published literature. METHODS: A voluntary 23-item online survey was distributed amongst all registered Swiss infectiologists and orthopedic surgeons in December 2011. The literature comparison was based on a systematic literature review. RESULTS: Overall response rate was 14 % (n = 117); 11 % (n = 92) were included in the final analysis. The overwhelming majority (91 %) of the respondents differentiated between SB and NSB, with determination predominantly based on clinical presentation (83 %), blood chemistry (75 %), and bursal aspirate (66 %). NSB was predominantly treated conservatively via immobilization (78 %) and anti-inflammatory medication (73 %). For SB, 85 % indicated surgical intervention, with 73 % prescribing concomitant antibiotics. Regarding antibiotic choice, 90 % used an aminopenicillin or its derivatives for a mean of 11 ± 5 days. The literature review revealed 66 relevant publications with an overall level of evidence of 2b, arguing for a conservative treatment approach in cases of SB or NSB. CONCLUSION: Therapeutic regimens for OB/PB differed considerably within Switzerland. Surgical intervention and antibiotic treatment was the most common therapy for SB, whereas a conservative approach predominated for NSB, which contrasts with the international literature. Clearly, prospective multicenter and multidisciplinary studies are needed to identify an optimal and cost-saving approach to the treatment of these common clinical entities.

[Standardized documentation in emergency departments with the core dataset of the DIVI]. / Standardisierte Dokumentation im Schockraum mit dem Kerndatensatz "Notaufnahme" der DIVI.

In Germany the documentation of every prehospital emergency medical treatment has been standardized since 1997 based on the core data-set MIND (minimal emergency physician data-set). Against this background it is very surprising that there is still no standardized data-set implemented for the documentation of early inhospital emergency care. In order to create such a data-set the current state of documentation in many different hospitals all over the country was scrutinized. In addition existing registries and international requirements were taken into consideration. Finally, a modular data-set was created using a Delphi process. This data-set was tested, clinically validated and finally ratified by the executive committee of the DIVI (German Interdisciplinary Association of Critical Care Medicine). The modular data-set was designed in such a way that a basic module forms the foundation for every patient. Process-oriented modules (e.g. surveillance) and symptom-oriented modules (e.g. trauma, neurology) were added if necessary. Along with this data-set a set of six modules was created for graphical representation when required. This high level of standardization not only allows an internal and external quality assessment but also provides a sophisticated documentation system especially to the trauma team in the emergency department. In terms of content major parameters of interhospital quality management are recorded and important factors of process management, such as MTS (Manchester triage system), ATLS (advanced trauma life support) and EWS (early warning score) have been implemented. The data-set includes all necessary information for transfers between physicians and non-academic staff as well as between physicians and could also be used as a fundamental discharge letter. Moreover, this new core data-set is the implementation of items required by existing registries into the daily routine documentation in order to reduce unnecessarily time-consuming and error-prone secondary data acquisition. For example, all items of the preclinical and emergency room documentation for the TraumaRegister DGU® (documentation phase S, A and B of the standard and QM form) have been included. This is sufficient for participation as a TraumaNetzwerk DGU® member as far as the early clinical treatment of multiple injured patients is concerned.

[Pelvic injuries in childhood and adolescence: Retrospective analysis of 5-year data from a national trauma centre]. / Beckenverletzungen im Kindes- und Jugendalter: Eine retrospektive Analyse eines überregionalen Traumazentrums über 5 Jahre.

BACKGROUND: Pelvic fractures are uncommon injuries in paediatric trauma patients because of specific anatomical features. Due to the low incidence there is no standardized therapeutic algorithm. MATERIAL AND METHODS: This retrospective review evaluates paediatric pelvic fractures of a Level I Trauma Centre over 5 years. In addition, we compared the data with adult pelvic fractures and reviewed the literature. A total of 37 pelvic fractures (≤16 years) were documented, with an incidence of 9.9% in the child with multiple injuries. The most common injury mechanisms were traffic accidents, followed by falls from heights. RESULTS: Type A injuries occurred in 50% (type B: 16%, type C: 27%, acetabular injuries: 11%). Osteosynthesis was performed in nine cases. Therapeutic intervention was necessary in three cases of haemodynamically relevant bleeding; 97% of all children had associated injuries (mean ISS: 38). CONCLUSION: Our data showed some differences to the literature. Pelvic fractures are predictors for high injury severity. Despite similar fracture pattern, in contrast to adults most injuries could be treated non-operatively. In unstable or dislocated fractures open reduction and stabilization must be performed.

[Time intervals during and after emergency room treatment. An analysis using the trauma register of the German Society for Trauma Surgery]. / Zeitintervalle während und nach Schockraumversorgung. Eine Analyse anhand des Traumaregisters der Deutschen Gesellschaft für Unfallchirurgie (DGU).

BACKGROUND: The prognosis of severely injured patients depends on a rapid diagnosis and early initiation of therapeutic procedures. MATERIAL AND METHODS: To that end a total of 6,927 prospectively documented severely injured patients with an Injury Severity Score (ISS) > or =16 from the Trauma Registry of the German Trauma Society (DGU, 2002-2007) were analyzed with respect to time intervals during emergency trauma treatment. RESULTS: In cases of indicated emergency surgery the average +/-time in the emergency department was 42+/-34 min, in cases of early surgery 75+/-41 min and in cases of transfer to the intensive care unit (ICU) 83+/-43 min, respectively. The time from the last diagnostic procedure until the end of emergency treatment was 12 min (emergency surgery), 26 min (early surgery) and 32 min (ICU), respectively. Level I (78 min) and level II (72 min) trauma centres showed similar mean times in the emergency department while level III trauma centres had a mean time of 86 min. According to this analysis no general correlation between shorter duration of emergency trauma care and reduced mortality could be observed. CONCLUSION: The duration of time intervals depends on injury severity, treatment after completion of emergency trauma care and the level of the trauma centre. Time management in emergency trauma care can potentially be optimized after completion of the last diagnostic procedure in the emergency room.

[Quality of prehospital and early clinical care of pediatric trauma patients of school age compared to an adult cohort. A matched-pair analysis of 624 patients from the DGU trauma registry]. / Prä- und frühklinische Versorgungsqualität pädiatrischer Traumapatienten im Schulalter im Vergleich mit dem Erwachsenenkollektiv. Matched-Pair-Analyse an 624 Patienten aus dem Traumaregister der DGU.

Conflicting reports exist regarding the quality of prehospital treatment of pediatric trauma patients. The purpose of this investigation was to determine whether prehospital treatment and emergency management in pediatric trauma patients were similar to that in adult patients. All patients who had been prospectively documented in the registry of the German Trauma Society (DGU) between 2002 and 2005 were selected for this study. A total of 312 matched pairs of adult and pediatric patients suffering from identical injuries were defined and compared with respect to cause of trauma, diagnostic and therapeutic interventions, and outcome. Within the study group, 63% were male, and the average age was 10.5+/-2.7 (SD) years in the pediatric group and 33.9+/-9.3 years in the adult group. There was no significant difference regarding prehospital intubation, reanimation, fluid management, chest drainage, ground and air transport to the hospital, time to arrival or interval in the emergency room. In contrast, significant differences (p<0.05) were observed in terms of the cause of trauma and pre-existing diseases. Pediatric trauma patients were not triaged or treated differently from adult trauma patients in respect to key issues of prehospital and early clinical trauma management.

[Interventional emergency embolization for severe pelvic ring fractures with arterial bleeding. Integration into the early clinical treatment algorithm]. / Interventionelle Notfallembolisation bei schweren Beckenfrakturen mit arterieller Blutung. Integration in den frühklinischen Behandlungsalgorithmus.

OBJECTIVE: Presentation of our own experiences and results of an early clinical algorithm for treatment integrating emergency embolization (TAE) in cases of unstable pelvic ring fractures with arterial bleeding. METHOD: Consecutive patient series from April 2002 to December 2006 at a level 1 trauma center. The data of the online shock room documentation (Traumawatch) of patients with a pelvic fracture and arterial bleeding detected on multislice computed tomography (MSCT) were examined for the following parameters: demographic data, injury mechanism, fracture classification according to Tile/AO and severity of the pelvic injury assessed with the Abbreviated Injury Score (AIS), accompanying injuries with elevation of the cumulative injury severity according to the Injury Severity Score (ISS), physiological admission parameters (circulatory parameters and initial Hb value) as well as transfusion requirement during treatment in the shock room, time until embolization, duration of embolization, and source of bleeding. RESULTS: Of a total of 162 patients, arterial bleeding was detected in 21 patients by contrast medium extravasation on MSCT, 12 of whom were men and 9 women with an average age of 45 (14-80) years. The mechanism of injury was high energy trauma in all cases. In 33% it involved type B pelvic fractures and in 67% type C fractures with an average AIS pelvis of 4.4 points (3-5) and a total severity of injury with the ISS of 37 points (21-66). Upon admission 47.6% presented hemodynamic instability with an average Hb value of 7.8 g/dl (3.2-12.4) and an average transfusion requirement of 6 red blood cell units (4-13). The time until the TAE was started was on average 62 min (25-115) with a duration period of the TAE of 25 min (15-67). Branches of the internal iliac artery were identified as the sole source of bleeding. The success rate of TAE amounted to over 90%. CONCLUSION: Interventional TAE represents an effective as well as a fast procedure for hemostasis of arterial bleeding detected on MSCT in patients with pelvic fractures. If an experienced radiologist on 24-h stand-by is assured and the infrastructure is efficient, this can be performed shortly after hospital admission and therefore should be integrated into the early clinical treatment protocol.

[Changes in geriatric traumatology. An analysis of 14,869 patients from the German Trauma Registry]. / Veränderungen in der Alterstraumatologie. Eine Analyse an 14.869 Patienten aus dem deutschen Traumaregister.

The increasing average age in the industrialized nations is leading to an increasing number of elderly traumatized patients. Against this background, an analysis of the age-specific characteristics of geriatric traumatized patients is necessary. In this study, 14,869 patients > or = 18 years were analysed, who were prospectively documented in the registry of the German Trauma Society (DGU) between 1996 and 2005. Patients between 18 and 59 years were defined as the control group; their proportion declined from 81.1% in 1996-2000 to 75.4% in 2001-2005. The average age rose from 41.0 years (1996) to 45.3 years (2005). With increasing age a significant increase in severe head injuries of up to 58.9% (> or = 80 years) could be observed. Older patients stayed for a significantly shorter time in hospital and on the ICU. With a comparable injury severity, the lethality after trauma increased with age (18-59 years 13.8%, 60-69 years 24.1%, 70-79 years 35.5%, > or = 80 years 43.6%). The multiply traumatized geriatric patient is different from the normal group in regard to type of injury, therapy and outcome and should therefore be treated taking this fact into consideration.
