Abstract
As compared with European practice, the American approach to resuscitation from traumatic haemorrhage de-emphasises pre-hospital interventions in favour of rapid transport to definitive care; limits initial surgical interventions under the damage control model; uses crystalloid as the initial fluid of choice; and follows an empiric 1:1:1 approach to transfusion with red cells, plasma and platelets in hemodynamically unstable and actively bleeding patients. The use of bedside visco-elastic testing to guide coagulation support is not as widespread as in Europe, while the early administration of tranexamic acid is more selective.

Abstract
OBJECTIVE To determine the number of imaging examinations, radiation dose and the time to complete trauma-related imaging in multiple trauma patients before and after introduction of whole-body CT (WBCT) into early trauma care. METHODS 120 consecutive patients before and 120 patients after introduction of WBCT into the trauma algorithm of the University Hospital Zurich were compared regarding the number and type of CT, radiography, focused assessment with sonography for trauma (FAST), additional CT examinations (defined as CT of the same body regions after radiography and/or FAST) and the time to complete trauma-related imaging. RESULTS In the WBCT cohort, significantly more patients underwent CT of the head, neck, chest and abdomen (p < 0.001) than in the non-WBCT cohort, whereas the number of radiographic examinations of the cervical spine, chest and pelvis and of FAST examinations were significantly lower (p < 0.001). There were no significant differences between cohorts regarding the number of radiographic examinations of the upper (p = 0.56) and lower extremities (p = 0.30). We found significantly higher effective doses in the WBCT (29.5 mSv) than in the non-WBCT cohort (15.9 mSv; p < 0.001), but fewer additional CT examinations for completing the work-up were needed in the WBCT cohort (p < 0.001). The time to complete trauma-related imaging was significantly shorter in the WBCT (12 min) than in the non-WBCT cohort (75 min; p < 0.001). CONCLUSION Including WBCT in the initial work-up of trauma patients results in higher radiation doses, but fewer additional CT examinations are needed, and the time for completing trauma-related imaging is shorter. ADVANCES IN KNOWLEDGE WBCT in trauma patients is associated with a high radiation dose of 29.5 mSv.

Abstract
Traumatic brain injury (TBI) is still the leading cause of disability in young adults worldwide. The major mechanisms - diffuse axonal injury, cerebral contusion, ischemic neurological damage, and intracranial hematomas have all been shown to be associated with mitochondrial dysfunction in some form. Mitochondrial dysfunction in TBI patients is an active area of research, and attempts to manipulate neuronal/astrocytic metabolism to improve outcomes have been met with limited translational success. Previously, several preclinical and clinical studies on TBI induced mitochondrial dysfunction have focused on opening of the mitochondrial permeability transition pore (PTP), consequent neurodegeneration and attempts to mitigate this degeneration with cyclosporine A (CsA) or analogous drugs, and have been unsuccessful. Recent insights into normal mitochondrial dynamics and into diseases such as inherited mitochondrial neuropathies, sepsis and organ failure could provide novel opportunities to develop mitochondria-based neuroprotective treatments that could improve severe TBI outcomes. This review summarizes those aspects of mitochondrial dysfunction underlying TBI pathology with special attention to models of penetrating traumatic brain injury, an epidemic in modern American society.

Abstract
Aims To recognize patients who require massive transfusion at the early stage of blunt trauma, we retrospectively investigated patients with high-energy blunt injuries transferred within 1 h post-trauma. Methods Between August 2007 and July 2011, 233 trauma patients were: (i) injured by a high-energy blunt mechanism with Injury Severity Score ≥9; (ii) not dead on arrival; (iii) older than 9 years; and (iv) at our center within 1 h after injury. The findings for 113 of those patients were analyzed, including those produced by ultrasonography, computed tomography, and arterial blood gas analyses. Results Of 113 patients, 33 underwent massive transfusion (≥6 units) within 8 h of arrival. A logistic regression analysis revealed that an arterial lactate level ≥28 mg/dL (P < 0.001; odds ratio, 105.11; 95% confidence interval, 12.58-2,718.84) and a flat ratio of the inferior vena cava on computed tomography ≥3 (P < 0.001; odds ratio, 32.50; 95% confidence interval, 4.44-714.44) were significant independent predictors for a massive transfusion within 8 h. In a receiver operating curve analysis, the area under the curve of the need for massive transfusion was 0.956, with a sensitivity of 0.94 and a specificity of 0.90. A linear predictive formula for the probability (P) of receiving a massive transfusion was generated as P = 2 × lactate (mg/dL) + 15 × the flat ratio of inferior vena cava - 103. Using another 52 trauma patients, the formula was validated. Conclusions An elevated level of arterial lactate and the flat ratio of inferior vena cava were significant predictors for identifying the patients who would require a massive transfusion in the early stage after high-energy blunt trauma.

Abstract
Uncontrolled bleeding is the leading cause of shock in trauma patients and delays in recognition and treatment have been linked to adverse outcomes. For prompt detection and management of hypovolaemic shock, ATLS(®) suggests four shock classes based upon vital signs and an estimated blood loss in percent. Although this classification has been widely implemented over the past decades, there is still no clear prospective evidence to fully support this classification. In contrast, it has recently been shown that this classification may be associated with substantial deficits. A retrospective analysis of data derived from the TraumaRegister DGU(®) indicated that only 9.3% of all trauma patients could be allocated into one of the ATLS(®) shock classes when a combination of the three vital signs heart rate, systolic blood pressure and Glasgow Coma Scale was assessed. Consequently, more than 90% of all trauma patients could not be classified according to the ATLS(®) classification of hypovolaemic shock. Further analyses including also data from the UK-based TARN registry suggested that ATLS(®) may overestimate the degree of tachycardia associated with hypotension and underestimate mental disability in the presence of hypovolaemic shock. This finding was independent from pre-hospital treatment as well as from the presence or absence of a severe traumatic brain injury. Interestingly, even the underlying trauma mechanism (blunt or penetrating) had no influence on the number of patients who could be allocated adequately. Considering these potential deficits associated with the ATLS(®) classification of hypovolaemic shock, an online survey among 383 European ATLS(®) course instructors and directors was performed to assess the actual appreciation and confidence in this tool during daily clinical trauma care. Interestingly, less than half (48%) of all respondents declared that they would assess a potential circulatory depletion within the primary survey according to the ATLS(®) classification of hypovolaemic shock. Based on these observations, a critical reappraisal of the current ATLS(®) classification of hypovolaemic seems warranted.

Abstract
BACKGROUND We aimed to systematically review the literature on the educational impact of Advanced Trauma Life Support (ATLS) courses and their effects on death rates of multiple trauma patients. METHODS All Medline, Pubmed, and the Cochrane Library English articles on the educational impact of ATLS courses and their effects on trauma mortality for the period 1966-2012 were studied. All original articles written in English were included. Surveys, reviews, editorials/letters, and other trauma courses or models different from the ATLS course were excluded. Articles were critically evaluated regarding study research design, statistical analysis, outcome, and quality and level of evidence. RESULTS A total of 384 articles were found in the search. Of these, 104 relevant articles were read; 23 met the selection criteria and were critically analyzed. Ten original articles reported studies on the impact of ATLS on cognitive and clinical skills, six articles addressed the attrition of skills gained through ATLS training, and seven articles addressed the effects of ATLS on trauma mortality. There is level I evidence that ATLS significantly improves the knowledge of participants managing multiple trauma patients, their clinical skills, and their organization and priority approaches. There is level II-1 evidence that knowledge and skills gained through ATLS participation decline after 6 months, with a maximum decline after 2 years. Organization and priority skills, however, are kept for up to 8 years following ATLS. Strong evidence showing that ATLS training reduces morbidity and mortality in trauma patients is still lacking. CONCLUSIONS It is highly recommended that ATLS courses should be taught for all doctors who are involved in the management of multiple trauma patients. Future studies are required to properly evaluate the impact of ATLS training on trauma death rates and disability.

Abstract
BACKGROUND Since the diagnostic yield of chest X-ray (CXR) is not high enough, when it is ordered for all the multiple trauma patients, this study was aimed to evaluate the relationship between clinical and CXR findings in order to formulate a clinical decision rule to prevent unnecessary CXR in these patients. METHODS Stable multiple blunt trauma patients referring to the ED were included. The clinical and radiographic findings of all the patients were collected and the relationships between these variables analysed. Finally, based on the regression coefficients (β) of the variables, the Thoracic Injury Rule-out Criteria (TIRC) were designed. RESULTS A total of 2607 patients were included (males: 78.9%, mean age: 34.1 ± 15.0 years). Age over 60 (β = 0.8; 95% CI: 0.27-1.34; P = 0.003), crepitation (β = 4.33; 95% CI: 1.65-7.0; P < 0.001), loss of consciousness (β = 3.16; 95% CI: 2.44-3.88; P < 0.001), decrease in pulmonary sounds (β = 2.67; 95% CI: 1.73-3.6; P < 0.001), chest wall pain (β = 2.12; 95% CI: 1.63-2.61; P < 0.001) and tenderness (β = 1.78; 95% CI: 1.26-2.27; P < 0.001), dyspnea (β = 1.3; 95% CI: 0.41-2.18; P = 0.004) and abrasion (β = 0.5; 95% CI: 0.22-0.83; P = 0.03) were independent factors predicting thoracic injury. CXR in stable conscious multiple blunt trauma patients under 60 years, without chest wall pain and tenderness, decrease in pulmonary sounds, crepitation, skin abrasion, and dyspnea did not provide any additional findings. CONCLUSIONS Based on TIRC, it seems that CXR in stable multiple blunt trauma patients who are conscious and under 60 and have no decrease in pulmonary sounds, no dyspnea, no thoracic skin abrasion, and no crepitation can be ignored.

Abstract
BACKGROUND This study evaluated 30-day morbidity and mortality and assessed pancreas-specific complications in patients with major pancreatic injuries who underwent a distal pancreatectomy. STUDY DESIGN Records of 107 consecutive patients who underwent a distal pancreatectomy at a Level 1 Trauma Centre in Cape Town between January 1982 and December 2011 were reviewed. Primary endpoints were postoperative morbidity and death. Complications were graded according to the Clavien-Dindo severity classification and the International Study Group of Pancreatic Surgery (ISGPS) definitions. RESULTS A total of 107 patients [94 men, median age 26, median RTS 7.8, 69 penetrating injuries (63 gunshot wounds, 6 stabs wounds), 38 blunt injuries] underwent distal pancreatectomy. Overall mortality was 12%, 16% for gunshot injuries, 8% for blunt trauma and 0% in patients who had stab wounds. Eighty patients had a post-operative complication. A pancreatic leak (n=26) was the most common pancreatic related complication. Median postoperative stay in 28 patients with no or grade I complications was 9 days; in 11 patients with grade II complications was 18 days; in 14 grade IIIa, 31 days; in 19 grade IIIb, 38 days; in 8 grade IVa, 33 days in 14 grade IVb, and in 13 grade V the duration of postoperative stay was 14±39.4 days. CONCLUSIONS Overall mortality for distal pancreatectomy was 12%. Pancreatic leak was a common cause of morbidity. Length of hospitalisation increased with increasing Clavien-Dindo severity grading. There was a significant difference in the duration of hospitalisation in patients with no or grade I complications compared to those with grade II-IV injuries (p<0.05).

Abstract
Background Recently, our group has proposed a new classification of hypovolemic shock based on the physiological shock marker base deficit (BD). The classification consists of four groups of worsening BD and correlates with the extent of hypovolemic shock in severely injured patients. The aim of this study was to test the applicability of our recently proposed classification of hypovolemic shock in the context of severe traumatic brain injury (TBI). Methods Between 2002 and 2011, patients ≥16 years in age with an AIShead ≥ 3 have been retrieved from the German TraumaRegister DGU® database. Patients were classified into four strata of worsening BD [(class I (BD ≤ 2 mmol/l), class II (BD > 2.0 to 6.0 mmol/l), class III (BD > 6.0 to 10 mmol/l) and class IV (BD > 10 mmol/l)] and assessed for demographic and injury characteristics as well as blood product transfusions and outcomes. The cohort of severely injured patients with TBI was compared to a population of all trauma patients to assess possible differences in the applicability of the BD based classification of hypovolemic shock. Results From a total of 23,496 patients, 10,201 multiply injured patients with TBI (AIShead ≥ 3) could be identified. With worsening of BD, a consecutive increase of mortality rate from 15.9% in class I to 61.4% in class IV patients was observed. Simultaneously, injury severity scores increased from 20.8 (±11.9) to 41.6 (±17). Increments in BD paralleled decreasing hemoglobin, platelet counts and Quick’s values. The number of blood units transfused correlated with worsening of BD. Massive transfusion rates increased from 5% in class I to 47% in class IV. Between multiply injured patients with TBI and all trauma patients, no clinically relevant differences in transfusion requirement or massive transfusion rates were observed. Conclusion The presence of TBI has no relevant impact on the applicability of the recently proposed BD-based classification of hypovolemic shock. This study underlines the role of BD as a relevant clinical indicator of hypovolaemic shock during the initial assessment in respect to haemostatic resuscitation and transfusion requirements.

Abstract
OBJECTIVE To discuss the current resuscitative strategies for trauma-induced hemorrhagic shock and acute traumatic coagulopathy (ATC). ETIOLOGY Hemorrhagic shock can be acutely fatal if not immediately and appropriately treated. The primary tenets of hemorrhagic shock resuscitation are to arrest hemorrhage and restore the effective circulating volume. Large volumes of isotonic crystalloids have been the resuscitative strategy of choice; however, data from experimental animal models and retrospective human analyses now recognize that large-volume fluid resuscitation in uncontrolled hemorrhage may be deleterious. The optimal resuscitative strategy has yet to be defined. In human trauma, implementing damage control resuscitation with damage control surgery for controlling ongoing hemorrhage, acidosis, and hypothermia; managing ATC; and restoring effective circulating volume is emerging as a more optimal resuscitative strategy. With hyperfibrinolysis playing an integral role in the manifestation of ATC, the use of antifibrinolytics (eg, tranexamic acid and aminocaproic acid) may also serve a beneficial role in the early posttraumatic period. Considering the sparse information regarding these resuscitative techniques in veterinary medicine, veterinarians are left with extrapolating information from human trials and experimental animal models. DIAGNOSIS Viscoelastic tests integrated with predictive scoring systems may prove to be the most reliable methods for early detection of ATC as well as for guiding transfusion requirements. SUMMARY Hemorrhage accounts for up to 40% of human trauma-related deaths and remains the leading cause of preventable death in human trauma. The exact proportion of trauma-related deaths due to exsanguinations in veterinary patients remains uncertain. Survivability depends upon achieving rapid definitive hemostasis, early attenuation of posttraumatic coagulopathy, and timely restoration of effective circulating volume. Early institution of damage control resuscitation in severely injured patients with uncontrolled hemorrhage has the ability to curtail posttraumatic coagulopathy and the exacerbation of metabolic acidosis and hypothermia and improve survival until definitive hemostasis is achieved.

Abstract
Cardiac arrest victims who present with pulseless electrical activity (PEA) usually have a grave prognosis. Several conditions, however, have cause-specific treatments which, if applied immediately, can lead to quick and sustained recovery. Current teaching focuses on recollection of numerous conditions that start with the letters H or T as potential causes of PEA. This teaching method is too complex, difficult to recall during resuscitation, and does not provide guidance to the most effective initial interventions. This review proposes a structured algorithm that is based on the differentiation of the PEA rhythm into narrow- or wide-complex subcategories, which simplifies the working differential and initial treatment approach. This, in conjunction with bedside ultrasound, can quickly point towards the most likely cause of PEA and thus guide resuscitation.

Abstract
Well-known global health priorities (malaria, pneumonia, sepsis, diarrhea, human immunodeficiency virus [HIV], tuberculosis, trauma), although very different threats to an individual’s health, share a common consequence: Development of acute, life-threatening illness. In the developed world, such illness is routinely treated in an intensive care unit (ICU) by highly specialized physicians, nurses and support staff. This model of intensive care is spreading rapidly to low and middle income countries and as it spreads, challenges and limitations to this model arise [1].

Abstract
BACKGROUND We performed this study to optimize reconstituted lyophilized plasma (LP) into a minimal volume fluid that provides effective hemostatic resuscitation for trauma while minimizing logistical limitations. METHODS We performed a prospective, blinded animal study. Plasma was lyophilized following whole blood collection from anesthetized swine. The minimal volume needed for reconstitution was determined, and this solution was evaluated for safe infusion into the swine. Reconstituted LP was analyzed for electrolyte content, osmolarity, and coagulation factor activity. Twenty swine were anesthetized and subjected to a validated model of polytrauma and hemorrhagic shock (including a Grade V liver injury), then randomized to resuscitation with LP reconstituted to either 100% of the original plasma volume (100%LP) or the minimal volume LP fluid. Physiologic data were monitored, and blood loss and hematocrit were measured. Coagulation status was evaluated using thrombelastography. RESULTS The minimal volume of reconstituted LP safe for infusion in swine was 50% of the original plasma volume (50%LP). The 50%LP had higher electrolyte concentrations, osmolarity, and increased coagulation factor activity levels by volume compared with 100%LP (p < 0.05). Blood loss, hematocrit, mean arterial pressure, and heart rate did not differ between animals receiving 100%LP (n = 10) or 50%LP (n = 10) at any time point (p > 0.05). International normalized ratio and thrombelastography parameters were not different between groups (R time, α angle, or maximal amplitude, p > 0.05). CONCLUSION Resuscitation with 50%LP fluid was well tolerated and equally effective compared with 100%LP, with respect to physiologic and hemostatic properties. The smaller volume of fluid necessary to reconstitute hypertonic LP makes it logistically superior to 100%LP for first responders and may reduce adverse effects of large-volume resuscitation.

Abstract
BACKGROUND Pericardiocentesis (PCC) had been taught as a mandatory skill in the Advanced Trauma Life Support (ATLS®) course as a bridge to definitive surgical therapy for traumatic pericardial tamponade since its inception in 1978. Immediate thoracotomy for penetrating trauma to the heart and chest has resulted in the decreased use of PCC in trauma. PCC is now offered as an optional skill in the ninth edition of the ATLS®. A review of the literature regarding the use and effectiveness of PCC in traumatic pericardial tamponade in the modern era is necessary to better define its current role in trauma care. METHODS Scientific publications from 1970 to 2010 involving PCC after trauma were identified. The Preferred Reporting Items for Systematic reviews and Meta-Analyses was used. Human studies describing acute traumatic tamponade were included. Publications involving nontraumatic or chronic pericardial tamponade from effusions caused by inflammatory, infectious, or neoplastic etiology were excluded. Publications were categorized by level of evidence. RESULTS Of the 135 publications identified, 27 were included, composing of 2,094 trauma patients with suspected cardiac tamponade. The reported use of PCC decreased from 45.9% of patients in the period 1970 to 1979 down to 6.4% of patients in the period between 2000 and 2010 (p < 0.05). Reported rates describing the use of PCC as the sole intervention decreased from 13.7% in the period 1970 to 1979 to 2.1% in the period 2000 to 2010 (p < 0.05). Survival analysis after PCC was possible for 380 patients. Overall survival following PCC was 83.4% (n = 317) and 91.8% (n = 145) when used as the sole intervention. In patients who received PCC then thoracotomy, survival rate was 79.5% (n = 178). CONCLUSION Studies on the use of PCC for trauma are limited and biased toward survivors. The reported survival rate is high. There remains a limited role for PCC in nontrauma centers where definitive surgical management is not immediately available and transport time to a higher level of care facility supports the use of temporary decompression by PCC. LEVEL OF EVIDENCE Systematic review, level III.

Abstract
BACKGROUND Emergency devices for pelvic ring stabilization include circumferential sheets, pelvic binders, and c-clamps. Our knowledge of the outcome of these techniques is currently based on limited information. METHODS Using the dataset of the German Pelvic Trauma Registry, demographic and injury-associated characteristics as well as the outcome of pelvic fracture patients after sheet, binder, and c-clamp treatment was compared. Outcome parameters included transfusion requirement of packed red blood cells, length of hospital stay, mortality, and incidence of lethal pelvic bleeding. RESULTS Two hundred seven of 6137 (3.4%) patients documented in the German Pelvic Trauma Registry between April 30th 2004 and January 19th 2012 were treated by sheets, binders, or c-clamps. In most cases, c-clamps (69%) were used, followed by sheets (16%), and binders (15%). The median age was significantly lower in patients treated with binders than in patients treated with sheets or c-clamps (26 vs. 47 vs. 42 years, p=0.01). Sheet wrapping was associated with a significantly higher incidence of lethal pelvic bleeding compared to binder or c-clamp stabilization (23% vs. 4% vs. 8%). No significant differences between the study groups were found in sex, fracture type, blood haemoglobin concentration, arterial blood pressure, Injury Severity Score, the incidence of additional pelvic packing and arterial embolization, need of red blood cell transfusion, length of hospitalisation, and mortality. CONCLUSIONS The data suggest that emergency stabilization of the pelvic ring by binders and c-clamps is associated with a lower incidence of lethal pelvic bleeding compared to sheet wrapping. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE For the early recognition and management of hypovolaemic shock, ATLS suggests four shock classes based upon an estimated blood loss in percent. The aim of this study was to assess the confidence and acceptance of the ATLS classification of hypovolaemic shock among ATLS course directors and instructors in daily trauma care. METHODS During a 2-month period, ATLS course directors and instructors from the ATLS region XV (Europe) were invited to participate in an online survey comprising 15 questions. RESULTS A total of 383 responses were received. Ninety-eight percent declared that they would follow the 'A, B, C, D, E' approach by ATLS in daily trauma care. However, only 48% assessed 'C-Circulation' according to the ATLS classification of hypovolaemic shock. One out of four respondents estimated that in daily clinical routine, less than 50% of all trauma patients can be classified according to the current ATLS classification of hypovolaemic shock. Additionally, only 10.9% considered the ATLS classification of hypovolaemic shock as a 'good guide' for fluid resuscitation and blood product transfusion, whereas 45.1% stated that this classification only 'may help' or has 'no impact' to guide resuscitation strategies. CONCLUSIONS Although the 'A, B, C, D, E' approach according to ATLS is widely implemented in daily trauma care, the use of the ATLS classification of hypovolaemic shock in daily practice is limited. Together with previous analyses, this study supports the need for a critical reassessment of the current ATLS classification of hypovolaemic shock.

Abstract
OBJECTIVE Emergency thoracotomy (ET) can be life-saving in highly selected trauma patients, especially after penetrating chest trauma. There is little information on the outcome of ET in European trauma centres. Here we report our experience in Iceland. MATERIAL AND METHODS This was a retrospective analysis of all patients who underwent ET in Iceland between 2005 and 2010. Patient demographics, mechanism, and location of major injury (LOMI) were registered, together with signs of life (SOL), the need for cardiopulmonary resuscitation (CPR), and transfusions. Based on physiological status from injury at admission, the severity score (ISS), revised trauma score (RTS), and probability of survival (PS) were calculated. RESULTS Of nine ET patients (all males, median age 36years, range 20-76) there were five long-term survivors. All but one made a good recovery. There were five blunt traumas (3 survivors) and four penetrating injuries (2 survivors). The most frequent LOMI was isolated thoracic injury (n=6), but three patients had multiple trauma. Thoracotomy was performed in five patients, sternotomy in two, and two underwent both procedures. One patient was operated in the ambulance and the others were operated after arrival. Median ISS and NISS were 29 (range 16-54) and 50 (range 25-75), respectively. Median RTS was 7 (range 0-8) with estimated PS of 85% (range 1-96%). Median blood loss was 10L (range 0.9-55). A median of 23 units of packed red blood cells were transfused (range 0-112). For four patients, CPR was required prior to transport; two others required CPR in the emergency room. Three patients never had SOL and all of them died. CONCLUSION ET is used infrequently in Iceland and the number of patients was small. More than half of them survived the procedure. This is especially encouraging considering how severely injured the patients were.

Abstract
INTRODUCTION The primary goal of this study was to compare the chest wall thicknesses (CWT) at the 2nd intercostal space (ICS) at the mid-clavicular line (MCL) and 5th ICS at the mid-axillary line (MAL) in a population of patients with a CT confirmed pneumothorax (PTX). This result will help physicians to determine the optimum needle thoracostomy (NT) puncture site in patients with a PTX. MATERIALS AND METHODS All trauma patients who presented consecutively to A&E over a 12-month period were included. Among all the trauma patients with a chest CT (4204 patients), 160 were included in the final analysis. CWTs were measured at both sides and were compared in all subgroup of patients. RESULTS The average CWT for men on the 2nd ICS-MCL was 38mm and for women was 52mm; on the other hand, on the 5th ICS-MAL was 33mm for men and 38mm for women. On the 2nd ICS-MCL 17% of men and 48% of women; on the 5th ICS-MAL 13% of men and 33% of women would be inaccessible with a routine 5-cm catheter. Patients with trauma, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 2nd ICS-MCL. Patients with trauma, lung contusion, sternum fracture, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 5th ICS-MAL. CONCLUSIONS This study confirms that a 5.0-cm catheter would be unlikely to access the pleural space in at least 1/3 of female and 1/10 of male Turkish trauma patients, regardless of the puncture site. If NT is needed, the 5th ICS-MAL is a better option for a puncture site with thinner CWT.

Abstract
INTRODUCTION Patients with pelvic fracture usually require transfers to trauma centers for additional advanced treatment. Patient safety during the transfer should always be a priority. The noninvasive pelvic circumferential compression device (PCCD) can reportedly provide a tamponade effect, which reduces hemorrhage. In the present study, we evaluated the feasibility and efficiency of PCCD in patients with pelvic fracture who required transfer to trauma centers. MATERIALS AND METHODS In the present study, we aimed to evaluate patients with pelvic fractures who were transferred from other hospitals. We investigated and compared the characteristics of these types of patients with and without pretransfer PCCD. We compared 2 groups (with and without pretransfer PCCD) of patients under different situations (unstable pelvic fracture, stable pelvic fracture, or indicated for transcatheter arterial embolization). We also analyzed the characteristics of patients with unstable pelvic fracture who were initially evaluated as having stable pelvic fracture primarily before being transferred. RESULTS During the 53-month period, we enrolled 585 patients in the study. The patients with unstable pelvic fractures who received pretransfer PCCDs required significantly fewer blood transfusions (398.4 ± 417.6 mL vs 1954.5 ± 249.0 mL, P < .001), shorter intensive care unit length of stay (LOS; 6.6 ± 5.2 days vs 11.8 ± 7.7 days, P = .024), and shorter hospital LOS (9.4 ± 7.0 days vs 19.5 ± 13.7 days, P = .006) compared with patients who did not receive the pretransfer PCCD. The stable patients who received pretransfer PCCDs required significantly fewer blood transfusions (120.2 ± 178.5 mL vs 231.8 ± 206.2 mL, P = .018) and had shorter intensive care unit LOS (1.7 ± 3.3 days vs 3.4 ± 2.9 days, P = .029) and shorter hospital LOS (6.8 ± 5.1 days vs 10.4 ± 7.6 days, P = .018) compared with patients who did not receive the pretransfer PCCD. CONCLUSION Pelvic circumferential compression devices benefit patients with pelvic fracture who need to be transferred to trauma centers. Pretransfer PCCDs appeared to be a feasible and safe procedure during the transfer. In discussions between the referring physicians and the receiving physicians, we recommend using pretransfer PCCDs.

Abstract
We reviewed recent data on the prevalence, risk factors, complications, and management of trauma during pregnancy. Using the terms "trauma" and "pregnancy" along with specified mechanisms of injury, we queried the PubMed database for studies reported from Jan. 1, 1990, through May 1, 2012. Studies with the largest number of patients for a given injury type and that were population-based and/or prospective were included. Case reports and case series were used only when more robust studies were lacking. A total of 1164 abstracts were reviewed and 225 met criteria for inclusion. Domestic violence/intimate partner violence and motor vehicle crashes are the predominant causes of reported trauma during pregnancy. Management of trauma during pregnancy is dictated by its severity and should be initially geared toward maternal stabilization. Minor trauma can often be safely evaluated with simple diagnostic modalities. Pregnancy should not lead to underdiagnosis or undertreatment of trauma due to unfounded fears of fetal effects. More studies are required to elucidate the safest and most cost-effective strategies for the management of trauma in pregnancy.

Abstract
A 59-year-old woman presented at the emergency department with cough and weakness that started a few days before. She had a history of breast cancer treated with mastectomy with negative followup. Physical examination revealed tachycardia and tachypnea, normal blood pressure, lower lobe crackles bilaterally, and jugular venous distention. Laboratory data underlined neutrophilic leukocytosis, mild renal failure, and high procalcitonin. Chest radiography revealed bilateral nodular lesions, presumably secondary. Patient was treated with fluid therapy and broad-spectrum antibiotic therapy because of suspected sepsis. In clinical revaluation patient showed systolic hypotension unresponsive to fluid resuscitation. Because of suspected pulmonary embolism an echocardiography was performed revealing normal dimensions of right ventricle with presence of a hypoechoic mass involving tricuspid annulus and obstructing the opening of anterior tricuspid flap; inferior vena cava appeared dilated and not collapsible. Subsequently, chest ultrasonography was performed, confirming multiple rounded lesions involving the pleura bilaterally, compatible with metastasis, and absence of interstitial syndrome. Finally a computed tomography scan of chest excluded pulmonary embolism and confirmed the presence of the obstructive mass responsible for hemodynamic instability together with pulmonary sepsis.

Abstract
This review describes the evidence exploring the use of a two-tier trauma team activation system, reviewing the background, history, data available and potential benefits and downsides. The current evidence suggests that a two-tier system may be a lean, cost-effective system, focussed on patient outcome, which could be implemented throughout the UK. Despite its current use in some hospitals, there is limited data from similar systems supporting this in a UK setting. Specific activation criteria need to be validated to ensure appropriate activation of trauma teams, ensuring optimal patient outcome and ensuring best practice.

Abstract
Introduction The recognition and management of hypovolemic shock still remain an important task during initial trauma assessment. Recently, we have questioned the validity of the Advanced Trauma Life Support (ATLS) classification of hypovolemic shock by demonstrating that the suggested combination of heart rate, systolic blood pressure and Glasgow Coma Scale displays substantial deficits in reflecting clinical reality. The aim of this study was to introduce and validate a new classification of hypovolemic shock based upon base deficit (BD) at emergency department (ED) arrival. Methods Between 2002 and 2010, 16,305 patients were retrieved from the TraumaRegister DGU® database, classified into four strata of worsening BD [class I (BD ≤ 2 mmol/l), class II (BD > 2.0 to 6.0 mmol/l), class III (BD > 6.0 to 10 mmol/l) and class IV (BD > 10 mmol/l)] and assessed for demographics, injury characteristics, transfusion requirements and fluid resuscitation. This new BD-based classification was validated to the current ATLS classification of hypovolemic shock. Results With worsening of BD, injury severity score (ISS) increased in a step-wise pattern from 19.1 (± 11.9) in class I to 36.7 (± 17.6) in class IV, while mortality increased in parallel from 7.4% to 51.5%. Decreasing hemoglobin and prothrombin ratios as well as the amount of transfusions and fluid resuscitation paralleled the increasing frequency of hypovolemic shock within the four classes. The number of blood units transfused increased from 1.5 (± 5.9) in class I patients to 20.3 (± 27.3) in class IV patients. Massive transfusion rates increased from 5% in class I to 52% in class IV. The new introduced BD-based classification of hypovolemic shock discriminated transfusion requirements, massive transfusion and mortality rates significantly better compared to the conventional ATLS classification of hypovolemic shock (p < 0.001). Conclusions BD may be superior to the current ATLS classification of hypovolemic shock in identifying the presence of hypovolemic shock and in risk stratifying patients in need of early blood product transfusion.

Abstract
OBJECTIVES The advanced trauma life support (ATLS) course has become the international standard for teaching trauma resuscitation skills. The 2 to 2.5 days course is usually offered as an on-site teaching experience. The present project assesses the potential for applying telemedicine technology to teaching ATLS by distance learning. DESIGN Two groups of equally trained first-year family practice residents were randomly assigned to a standard on-site ATLS course or one delivered by telemedicine. The 2 courses were compared by evaluating post-ATLS multiple-choice question test performance, instructor evaluation of student skill station performance, overall pass rate, participant rating of each component of the course, and overall feedback on the educational quality of the course (rating scale 1-4). RESULTS The mean scores for the 2 groups (with the standard ATLS and with the telemedicine, respectively) were not statistically significantly different: post-ATLS multiple-choice question-89.69% vs 85.89%; pass rate for the course was the same for both models; instructor overall evaluation of student skill station performance-3.12 vs 3.00; and participant overall feedback on all components of the course-3.67 vs 3.91. CONCLUSIONS Our results suggest that telemedicine technology could be successfully applied to teaching ATLS courses.

Abstract
A shift of approach from ‘clinics trying to fit physiology’ to the one of ‘physiology to clinics’, with interpretation of the clinical phenomena from their physiological bases to the tip of the clinical iceberg, and a management exclusively based on modulation of physiology, is finally surging as the safest and most efficacious philosophy in hemorrhagic shock. ATLS® classification and recommendations on hemorrhagic shock are not helpful because antiphysiological and potentially misleading. Hemorrhagic shock needs to be reclassified in the direction of usefulness and timing of intervention: in particular its assessment and management need to be tailored to physiology.

Abstract
BACKGROUND Vascular occlusive events can complicate recovery following trauma. We examined risk factors for venous and arterial vascular occlusive events in trauma patients and the extent to which the risk of vascular occlusive events varies with the severity of bleeding. METHODS AND FINDINGS We conducted a cohort analysis using data from a large international, double-blind, randomised, placebo-controlled trial (The CRASH-2 trial) [1]. We studied the association between patient demographic and physiological parameters at hospital admission and the risk of vascular occlusive events. To assess the extent to which risk of vascular occlusive events varies with severity of bleeding, we constructed a prognostic model for the risk of death due to bleeding and assessed the relationship between risk of death due to bleeding and risk of vascular occlusive events. There were 20,127 trauma patients with outcome data including 204 (1.01%) patients with a venous event (pulmonary embolism or deep vein thrombosis) and 200 (0.99%) with an arterial event (myocardial infarction or stroke). There were 81 deaths due to vascular occlusive events. Increasing age, decreasing systolic blood pressure, increased respiratory rates, longer central capillary refill times, higher heart rates and lower Glasgow Coma Scores (all p<0.02) were strong risk factors for venous and arterial vascular occlusive events. Patients with more severe bleeding as assessed by predicted risk of haemorrhage death had a greatly increased risk for all types of vascular occlusive event (all p<0.001). CONCLUSIONS Patients with severe traumatic bleeding are at greatly increased risk of venous and arterial vascular occlusive events. Older age and blunt trauma are also risk factors for vascular occlusive events. Effective treatment of bleeding may reduce venous and arterial vascular occlusive complications in trauma patients.

Abstract
BACKGROUND Major trauma is the leading worldwide cause of death in young adults. The mortality from traumatic cardiac arrest remains high but survival with good neurological outcome from cardiopulmonary arrest following major trauma has been regularly reported. Rapid, effective intervention is required to address potential reversible causes of traumatic cardiac arrest if the victim is to survive. Current ILCOR guidelines do not contain a standard algorithm for management of traumatic cardiac arrest. We present a simple algorithm to manage the major trauma patient in actual or imminent cardiac arrest. METHODS We reviewed the published English language literature on traumatic cardiac arrest and major trauma management. A treatment algorithm was developed based on this and the experience of treatment of more than a thousand traumatic cardiac arrests by a physician - paramedic pre-hospital trauma service. RESULTS The algorithm addresses the need treat potential reversible causes of traumatic cardiac arrest. This includes immediate resuscitative thoracotomy in cases of penetrating chest trauma, airway management, optimising oxygenation, correction of hypovolaemia and chest decompression to exclude tension pneumothorax. CONCLUSION The requirement to rapidly address a number of potentially reversible pathologies in a short time period lends the management of traumatic cardiac arrest to a simple treatment algorithm. A standardised approach may prevent delay in diagnosis and treatment and improve current poor survival rates.

Abstract
BACKGROUND The aim of this study was to establish the profile and outcomes of paediatric major trauma care (PTMC) within an integrated inclusive regionalised trauma system. METHODS Prospectively collected data from July 2001 to June 2009 from the Victorian State Trauma Registry of patients aged <18 years were reviewed. RESULTS There were 1634 major trauma cases with a median (IQR) age of 13 (6-16) years and 69% were male. The median ISS (IQR) was 18 (16-26). There were 1361 patients treated at a major trauma centre of which 69% (n=943) were treated at the PMTC. Head injury (AIS>2) was the most frequent injury (n=950, 58%). Surgery was required in 39% (n=637) of all cases; 437 patients in the 10-17 year old group and 200 patients in the 0-9 year old group; the mortality was 6.6%. There were 530 patients (32.4%) ventilated in ICU; these had a median ISS (IQR) of 25 (17-34) and mortality of 7.4%. Improvements in risk-adjusted mortality have occurred as the years have progressed [adjusted OR 95% CI: 0.87 (0.76, 0.99)] and being treated at a Level 1 trauma centre was associated with lower adjusted odds of mortality [adjusted OR 95% CI: 0.27 (0.11, 0.68)]. CONCLUSION The establishment of this integrated inclusive regionalised trauma system has been associated with progressively improving risk-adjusted mortality. The relatively low volume of major trauma requiring surgery in the 0-9 year old age group is notable, creating a challenging environment for maintaining skills and institutional preparedness.

Abstract
Pulmonary complications are prevalent in the critically ill neurological population. Respiratory failure, pneumonia, acute lung injury and the acute respiratory distress syndrome (ALI/ARDS), pulmonary edema, pulmonary contusions and pneumo/hemothorax, and pulmonary embolism are frequently encountered in the setting of severe brain injury. Direct brain injury, depressed level of consciousness and inability to protect the airway, disruption of natural defense barriers, decreased mobility, and secondary neurological insults inherent to severe brain injury are the main cause of pulmonary complications in critically ill neurological patients. Prevention strategies and current and future therapies need to be implemented to avoid and treat the development of these life-threatening medical complications.

Abstract
Background Trauma teams improve the initial management of trauma patients. Optimal timing of trauma alerts could improve team preparedness and performance while also limiting adverse ripple effects throughout the hospital. The purpose of this study was to evaluate how timing of trauma team activation and notification affects initial in-hospital management of trauma patients. Methods Data from a single hospital trauma care quality registry were matched with data from a trauma team alert log. The time from patient arrival to chest X-ray, and the emergency department length of stay were compared with the timing of trauma team activations and whether or not trauma team members received a preactivation notification. Results In 2009, the trauma team was activated 352 times; 269 times met the inclusion criteria. There were statistically significant differences in time to chest X-ray for differently timed trauma team activations (P = 0.003). Median time to chest X-ray for teams activated 15–20 minutes prearrival was 5 minutes, and 8 minutes for teams activated <5 minutes before patient arrival. Timing had no effect on length of stay in the emergency department (P = 0.694). We found no effect of preactivation notification on time to chest X-ray (P = 0.474) or length of stay (P = 0.684). Conclusion Proactive trauma team activation improved the initial management of trauma patients. Trauma teams should be activated prior to patient arrival.
