RESUMEN

BACKGROUND: The presence of abdominal injuries has a major impact on the mortality of severely injured patients. For injuries that require surgery, laparotomy is still the gold standard for early surgical care; however, there is increasing evidence that laparoscopy may be an alternative in the early clinical care of polytrauma patients. OBJECTIVE: The present registry-based study analyzed the utilization and the outcome of laparoscopy in severely injured patients with abdominal trauma in Germany. MATERIAL AND METHODS: A retrospective analysis of 12,447 patients retrieved from the TraumaRegister DGU® (TR-DGU) was performed. The primary inclusion criteria were an injury severity score (ISS) ≥ 9 and an abbreviated injury scale (AIS) [abdomen] ≥ 1. The included patients were grouped according to early treatment management: (1) laparoscopy, (2) laparotomy and (3) non-operative management (NOM). Finally, group-specific patient characteristics and outcome were analyzed. RESULTS: The majority of patients were treated by NOM (52.4%, n = 6069), followed by laparotomy (50,6%, n = 6295) and laparoscopy (0.7%, n = 83). The majority of laparoscopies were performed in patients with an AIS [abdomen] ≤ 3 (86.7%). The ISS of the laparoscopy group was significantly lower compared to that of the laparotomy and NOM groups (ISS 23.4 vs. 34.5 vs. 28.2, respectively, p ≤ 0.001). The standardized mortality rate (SMR), defined as the ratio between observed and expected mortality, was lowest in the patients receiving laparoscopy followed by laparotomy and NOM (SMR 0.688 vs. 0.931 vs. 0.932, respectively, p-value = 0.2128) without achieving statistical significance. CONCLUSION: Despite being rarely employed the data indicate the effectiveness of laparoscopy for the early treatment of severely injured, hemodynamically stable patients with an AIS [abdomen] ≤ 3.

RESUMEN

BACKGROUND: Previous studies revealed evidence that induced hypothermia attenuates ischemic organ injuries after severe trauma. In the present study, the effect of hypothermia on liver damage was investigated in a porcine long term model of multi-system injury, consisting of blunt chest trauma, penetrating abdominal trauma, musculoskeletal injury, and hemorrhagic shockMETHODS: In 30 pigs, a standardized polytrauma including blunt chest trauma, penetrating abdominal trauma, musculoskeletal injury, and hemorrhagic shock of 45% of total blood volume was induced. Following trauma, hypothermia of 33∘C was induced for 12 h and intensive care treatment was evaluated for 48 h. As outcome parameters, we assessed liver function and serum transaminase levels as well as a histopathological analysis of tissue samples. A further 10 animals served as controls. RESULTS: Serum transaminase levels were increased at the end of the observation period following hypothermia without reaching statistical significance compared to normothermic groups. Liver function was preserved (p⩽ 0.05) after the rewarming period in hypothermic animals but showed no difference at the end of the observation period. In H&E staining, cell death was slightly increased hypothermic animals and caspase-3 staining displayed tendency towards more apoptosis in hypothermic group as well. CONCLUSIONS: Induction of hypothermia could not significantly improve hepatic damage during the first 48 h following major trauma. Further studies focusing on multi-organ failure including a longer observation period are required to illuminate the impact of hypothermia on hepatic function in multiple trauma patients.

RESUMEN

BACKGROUND: In recent years, there has been an ongoing improvement in the treatment and structural aspects of acute trauma care. Because of the definition of rehabilitation as a post-acute part of the treatment of traumatic injuries, especially in multiple injured patients, there is need to improve the interaction and cooperation between acute care hospitals and rehabilitation clinics. This article gives a survey of the current state of rehabilitation in Germany. MATERIALS AND METHODS: Based on a directory of rehabilitation clinics and an internet search, all rehabilitation clinics were identified and included in the analysis for clinic location, structural and equipment attributes. RESULTS: In total 551 rehabilitation clinics with expertise in the treatment of traumatic and orthopedic injuries were identified. In detail, broad differences between the federal states could be observed. The number of rehabilitation clinics per state ranged from 1 to 136 and the number of beds from 70 to 18040. The average catchment area covered by a rehabilitation clinic is 648 km(2) (range 149-2106 km(2)) with an average of 1584 patients per clinic per year. Of the clinics 68% can treat patients with methicillin-resistant Staphylococcus aureus (MRSA) infections and 62.1% are able to deal with patients who need renal dialyses. Almost all clinics provide an x-ray facility (96.4%) while computed tomography (CT) and magnetic resonance imaging (MRI) are available in 52.6% and 50.3%, respectively. CONCLUSION: The number of rehabilitation clinics available seems to be adequate for all patients with traumatic injuries but there are enormous differences between the federal states. Because rehabilitation is important for the outcome of multiple injured patients, a further improvement of the quality and integration into the regional trauma network seem to be necessary.

RESUMEN

INTRODUCTION: Following the establishment of the first trauma networks in 2009 an almost nationwide certification could be achieved. Despite the impressive number of 46 certified networks, little is known about the actual improvements and the satisfaction of the participating hospitals. OBJECTIVES: This article aims to give a first representative overview of the expectations and actual achievements. MATERIAL AND METHODS: An online survey with a total of 36 questions was conducted in 884 hospitals. The questionnaire could be filled out online, sent by post or fax to the AKUT- Office. Descriptive statistical analyses were performed with Microsoft Excel. RESULTS: With 326 responses, a response rate of 48.9% of all active hospitals was achieved. Of the participating hospitals 64.1% (209) were certified and had taken part in the project for an average of 3.9 years. The average score for satisfaction was 2.3, 72.4% (236) felt that there was a need for improvement in the care of severely injured patients and 46.6% (152) in the transfer of patients. In 47.2% (142) no improvement in cooperation with the ambulance service could be determined, 25.2% (82) documented an increase in the number of severely injured patients since participating in the trauma network (TNW-DGU) and 93.9% (306) of all hospitals wanted to participate in the trauma network in the future. DISCUSSION: It could be shown that important goals, such as simplification of patient transfer or general improvement in cooperation have been achieved. Overall there was a high level of satisfaction among the participating hospitals; however, the survey has identified some points which need to be improved by further intensive work.

RESUMEN

BACKGROUND: An animal polytrauma model was developed, including trunk and extremity injuries combined with hemorrhagic shock and a prolonged post-traumatic phase. This could be useful for the assessment of different therapeutic approaches during intensive care therapy. METHODS: A standardized polytrauma including lung contusion, liver laceration and lower leg fracture was applied in 25 pigs. They underwent controlled haemorrhage either with a blood volume loss of 45 % and a median arterial pressure (MAP) <30 mmHg/90 min (group L, n = 15) or a 50 % blood loss of and an MAP <25 mmHg/120 min (group H, n = 10). Five non-traumatized pigs served as a control (group C). Subsequently, intensive care treatment was given for an observational period of 48 h. RESULTS: Both trauma groups showed signs of shock and organ injury (heart rate, MAP and lactate). The frequency of cardiopulmonary resuscitation (CPR) and lung injury was directly related to the severity of the haemorrhagic shock (CPR-group L: 4 of 15 pigs, group H: 4 of 10 pigs; Respiratory failure-group L: 3 of 13, group H: 3 of 9. There was no difference in mortality between trauma groups. CONCLUSION: The present data suggest that our model reflects the mortality and organ failure of polytrauma in humans during shock and the intensive care period. This suggests that the experimental protocol could be useful for the assessment of therapeutic approaches during the post-traumatic period.

RESUMEN

BACKGROUND: The number of (seriously) injured children increased again for the first time in 2011. The aim of this study was to analyse differences compared to multiple injured adults and to show the reality of daily treatment. METHODS: All cases of the DGU Trauma Registry from the years 1997 to 2010 were examined. The documented cases were divided into different the age groups. The study investigated, e.g. the mechanism of accident, injury pattern, the number of hospital and ICU days, and lethality. RESULTS: At 38.8% the largest percentage of severely injured children and adolescents belongs to the group of 16-17 year olds. The group of 0-5 year olds (15.9%) has the lowest percentage. The most common accident cause was traffic accidents (58.5%). The mechanism of accident and the injury patterns changes with age. Younger patients are often treated in supraregional trauma centers (0-5 year olds: 78.2% vs. 16-17 year olds: 73.1% vs. > 65 years: 63.2%). The average lethality rate was 14.8% (16.3% RISC). CONCLUSIONS: The percentage of severely injured children in the overall population is only 7.4%. Because the majority of patients are primarily treated in supraregional trauma centers, trauma centers with specialisation in paediatric traumatology are mandatory.

RESUMEN

AIM OF THE STUDY: Treatment strategies in distal radius fractures differ nationally and internationally. Conservative and operative treatment options compete as well as implants, postoperative therapy regimens and the necessity of implant removal. In our institution operative treatment is favoured. In the following the results of 721 surgically treated patients are presented. PATIENTS: PATIENTS who underwent operative treatment of their distal radius fractures in our institution between 2008 and 2011 were retrospectively analysed. Following patient characteristics have been surveyed regarding age, sex, location of plate osteosynthesis, operation time, time of cast immobilisation and complications like infections, tendon ruptures, need of revision surgery. RESULTS: 721 patients (mean age: 59.03 years) were retrospectively analysed. 514 of them (71.29 %) were female. Time of operation was after a mean duration of 5.48 days. In 558 (77.39 %) patients we performed palmar plate osteosynthesis. 89 (12.34 %) had dorsal plate osteosynthesis and 74 (10.3 %) cases were treated with either K-wires or screws. 18 (2.5 %) patients had concomitant traumatic carpal tunnel syndrome and a concomitant SL rupture was seen in 38 (5.27 %) patients. 40 (5.55 %) patients underwent operative revision because of posttraumatic carpal tunnel syndrome (n = 15), tendon ruptures (n = 7), malposition of screws (n = 6), loss of reduction (n = 6) and infection (n = 3). Mean duration of in-hospital stay after operation was 6.6 days. Implant removal was performed in 77 (10.7) patients; 59 (8.2 %) patients had palmar plate osteosynthesis and 18 (2.5 %) patients had dorsal plating. CONCLUSION: Because of the low complication rate after operative treatment of distal radius fractures, osteosynthesis of this fracture seems to be warranted. Regarding the patients' higher age we have seen an unexpectedly long in-hospital stay with a mean time of 6.6 days. Herein attempts should be made to reduce time of in-hospital stay. In our opinion implant removal should not be recommended routinely.

RESUMEN

Abdominal trauma represents the leading cause of haemorrhagic shock in the severely injured patient and is associated with high mortality and morbidity rates. The trauma surgeon has a central role in the multidisciplinary team addressing the specific diagnostic and therapeutic needs of patients with abdominal trauma. The management of blunt and penetrating abdominal trauma has undergone substantial changes in recent decades. Major innovations have been established in the field of diagnostic imaging and of nonoperative interventions such as angioembolization and endoscopic procedures. Another key development is the introduction of the damage control concept for the care of patients with abdominal trauma. The present manuscript comprises a review of the current management of abdominal trauma with an emphasis on diagnostic and therapeutic innovations.

RESUMEN

BACKGROUND: During the treatment of severely injured patients, rehabilitation takes an important role. In this study we examined the present structures in acute care hospitals, which influence the process of rehabiliation. MATERIALS AND METHODS: The data was captured in a questionnaire. The questions deal with the personal and structural situation of acute care hospitals in Germany. The questionnaires were sent to all clinics, which are registered in the TraumaNetwork DGU. RESULTS: 424 hospitals answered the questionnaire. This is a response rate of 57.3% regarding 740 acitve clinics in the TraumaNetwork DGU. 58% have no opportunity for rehabilitation. The majority of the hospitals have a physiotherapy, (98.6%) or an occupational therapy (71.0%); 33.3% have a case management. Only 17.0% of the hospitals have rehabilitation teams which take care during the hospital stay. These teams consist mainly of internal rehabilitation physicians and physical therapists. Supraregional Trauma Center have better organized structures, as hospitals with lower level of care. Only 56.6% of all hospitals reported that they were familiar with the cooperating rehabilitation hospitals. There are special cooperations with rehabilita­tion hospitals in 34.4% of all cases. CONCLUSION: The early mobilisation of severely injured patients is an integral part of the postoperative course in German hospitals. While on the one hand a large number of hospitals have good structural conditions on the other hand these structures are little integrated in the daily treamtment. There are major gaps and uncertainties in the cooperation between acute care clincs and rehabilitation hospitals. The integra­tion of rehabilitation hospitals in the TraumaNetwork DGU could be a good chance to improve this collaboration.

RESUMEN

BACKGROUND: The TraumaNetwork DGU® (TNW) connects hospitals with different capacities for the treatment of severely injured patients who work together as superregional (STC), regional (RTC) and local trauma centres (LTC). The standards of treatment and equipment are defined on the basis of current guidelines as published in the"White book of the Treatment of Severely Injured Patients". An external audit process evaluates the organisation and structure of participating hospitals as well as the cooperation of the trauma centres within a regional TNW. RESULTS: In May 2013 a total of 618 hospitals were visited and assessed according to the White book and 39 fully certified regional TNWs covered around 85% of the area of Germany. Treatment quality in the certified TCs was analyzed on the basis of 25,249 severely injured patients in the TraumaRegister DGU® (2008-2011) and significant differences between the expected and observed mortality rates were found. These differences were most obvious in superregional and regional trauma centres. CONCLUSION: The TraumaNetwork represents an innovative, cooperative project for successfully improving the treatment of severely injured patients.

RESUMEN

In Germany, approximately 35,000 patients with major injuries are treated per year. The treatment of patients suffering from major injuries is both a medical and a logistic challenge. Despite the high-level quality of medical care, regional differences exist due to geographical and infrastructural conditions. In addition, discrepancies in human resources and technical equipment in hospitals influence diagnostics and treatment of severely injured patients. Based on these findings trauma networks of the German Trauma Association were founded to guarantee nationwide high-quality medical care of these patients. This article provides an overview about requirements of all involved professions and establishment of trauma networks considering state-of-the-art communication technology. Moreover, characteristics of the auditing and certification process and planning of the integration of rehabilitation facilities are described.

RESUMEN

PURPOSE: The care for severely injured patients is a demanding task for all medical professionals involved in both the pre-clinical and the clinical setting. While the overall quality of care in Germany is high, regional differences remain. These are due to geographical and infrastructural variations, as well as different personnel and equipment situations in the hospitals. METHODS: In September 2006, the white paper 'Treatment of the severely injured' was published by the German Society of Trauma Surgery (DGU). The white paper asks for the improvement of comprehensive care and postulates the foundation of networks between trauma centres: a regional TraumaNetwork (TNW). All hospitals within a TNW are classified as local, regional or supraregional trauma centres by distinct criteria regarding personnel and equipment, as well as admission capacity and responsibility. Furthermore, agreements between the trauma centres and the pre-hospital rescue systems regulate the admission and transfer of patients in a TNW. RESULTS: To date, 878 hospitals are registered in 53 regional TNWs. A total of 511 hospitals have already been audited on-site. Preparing for the audit, 54.4% of the hospitals implemented organisational changes (e.g. inter-disciplinary guidelines), while 31.4% introduced personnel and 14.7% structural (e.g. X-ray in the emergency room [ER]) changes. In September 2011, the certification process was completed in 19 TNWs, comprising a mean of 14 (range 5-26) hospitals each. Moreover, international TNWs in co-operation with hospitals in Holland, Luxemburg, Switzerland and Austria were established. CONCLUSIONS: The TraumaNetwork DGU(®) audits all hospitals participating in the care for severely injured patients and establishes a structured network between all the players involved in trauma care. Thirty TNWs will be certified by the end of 2011, covering 75% of Germany. The nationwide covering will be completed by the middle of 2012.

RESUMEN

The sonograms of 115 infants with normal renal function ranging in age from 1 to 120 days used to determine renal parenchymal echogenicity by densitometry. The measured values were contrasted with the evaluations of 4 independent examiners who rated renal echogenicity as "less than", "equal to" or "greater than" that of the liver. The results revealed that naked eye evaluation does not permit a clear distinction between the categories of echogenicity and also that the assessments of the individual examiners differed considerably. Contrary to the previously held view the present findings indicate that the initially increased renal parenchymal echogenicity in neonates has developed into the normal hypoechoic condition after 1 month. One should take these findings into account when evaluating renal sonograms of infants, especially if no densitometric data are available.
