UNASSIGNED: The clinical impact of signs of life (SOLs) in traumatic cardiac arrest (TCA) remains to be elucidated. The aim of this study was to examine the association between SOLs and survival/neurological outcomes in TCA patients.
UNASSIGNED: Retrospective data from the Japan Trauma Data Bank (2019-2021) was reviewed. TCA patients were assigned to one of two study groups based on the presence or absence of SOLs and compared. SOLs were defined as having at least one of following criteria: pulseless electrical activity >40 beats per minute, gasping, positive light reflex, or extremity/eye movement at hospital arrival. The primary outcome was survival at hospital discharge. The secondary outcome was favorable neurological status (Glasgow Outcome Scale score of 4 or 5) at hospital discharge.
UNASSIGNED: A total of 1,981 patients (114 with SOLs and 1,867 without SOLs) were included. Characteristics of patients were as follows: age (median age 60.0 years old [interquartile range: 41-80] years vs. 55.4 [38-75] years), gender (male: 76/114 (66.7%) vs. 1,207/1,867 (65.0%), blunt trauma (90/111 [81.1%] vs. 1,559/1,844 [84.5%]), Injury Severity Score (29.2 [22-41] vs. 27.9 [20-34]). Patients with SOLs showed higher survival (10/114 (8.8%) vs. 25/1,867 (1.3%), OR 1.96 [CI 1.20-2.72]) and higher favorable neurological outcomes (4/110 (3.5%) vs. 6/1,865 (0.3%), OR 2.42 [CI 1.14-3.70]) compared with patients without SOLs.
UNASSIGNED: TCA patients with SOLs at hospital arrival showed higher survival and favorable neurological outcomes at hospital discharge compared with TCA patients without SOLs.

OBJECTIVE: To determine the feasibility and diagnostic accuracy of fast whole-body magnetic resonance imaging (WB-MRI) compared to whole-body computed tomography (WB-CT) in detecting injuries of slightly to moderately injured trauma patients.
METHODS: In a prospective single-center approach, trauma patients from convenience sampling with an expected Abbreviated Injury Scale (AIS) score ≤ 3 at admission, received an indicated contrast-enhanced WB-CT (reference standard) and a plain WB-MRI (index test) voluntarily up to five days after trauma. Two radiologists, blinded to the WB-CT findings, evaluated the absence or presence of injuries with WB-MRI in four body regions: head, torso, axial skeleton, and upper extremity. Diagnostic accuracy was determined using sensitivity, specificity, positive predictive value, and negative predictive value by body region.
RESULTS: Between June 2019 and July 2021, 40 patients were assessed for eligibility of whom 35 (median age (interquartile range): 50 (32.5) years; 26 men) received WB-MRI. Of 140 body regions (35 patients × 4 regions), 31 true positive, 6 false positive, 94 true negative, and 9 false negative findings were documented with WB-MRI. Thus, plain WB-MRI achieved a total sensitivity of 77.5% (95%-confidence interval (CI): (61.6-89.2%)), specificity of 94% (95%-CI: (87.4-97.8%)), and diagnostic accuracy of 89.3% (95%-CI: (82.9-93.9%)). Across the four regions sensitivity and specificity varied: head (66.7%/93.1%), torso (62.5%/96.3%), axial skeleton (91.3%/75%), upper extremity (33.3%/100%). Both radiologists showed substantial agreement on the WB-MRI reading (Cohen\'s Kappa: 0.66, 95%-CI: (0.51-0.81)).
CONCLUSIONS: Regarding injury detection, WB-MRI is feasible in slightly to moderately injured trauma patients, especially in the axial skeleton.
CONCLUSIONS: Besides offering a radiation-free approach, whole-body MRI detects injuries almost identically to whole-body CT in slightly to moderately injured trauma patients, who comprise a relevant share of all trauma patients.
CONCLUSIONS: Whole-body MRI could offer radiation-free injury detection in slightly to moderately injured trauma patients. Whole-body MRI detected injuries almost identically compared to whole-body CT in this population. Whole-body MRI could be a radiation-free approach for slightly to moderately injured young trauma patients.

BACKGROUND: The quality and promptness of prehospital care for major trauma patients are vital in order to lower their high mortality rate. However, the effectiveness of this response in Portugal is unknown. The objective of this study was to analyze response times and interventions for major trauma patients in the central region of Portugal.
METHODS: This was a retrospective, descriptive study, using the 2022 clinical records of the National Institute of Medical Emergency\'s differentiated resources. Cases of death prior to arrival at the hospital and other non-transport situations were excluded. Five-time intervals were determined, among which are the response time (T1, between activation and arrival at the scene), on-scene time (T2), and transportation time (T5; between the decision to transport and arrival at the emergency service). For each ambulance type, averages and dispersion times were calculated, as well as the proportion of cases in which the nationally and internationally recommended times were met. The frequency of recording six key interventions was also assessed.
RESULTS: Of the 3366 records, 602 were eliminated (384 due to death), resulting in 2764 cases: nurse-technician ambulance (SIV) = 36.0%, physician- nurse ambulance (VMER) = 62.2% and physician-nurse helicopter = 1.8%. In a very large number of records, it was not possible to determine prehospital care times: for example, transport time (T5) could be determined in only 29%, 13% and 8% of cases, respectively for SIV, VMER and helicopter. The recommended time for stabilization (T2 ≤ 20 min) was met in 19.8% (SIV), 36.5% (VMER) and 18.2% (helicopter). Time to hospital (T5 ≤ 45 min) was achieved in 80.0% (SIV), 93.1% (VMER) and 75.0% (helicopter) of the records. The administration of analgesia (42% in SIV) and measures to prevent hypothermia (23.5% in SIV) were the most recorded interventions.
CONCLUSIONS: There was substantial missing data on statuses and a lack of information in the records, especially in the VMER and helicopter. According to the records, the time taken to stabilize the victim on-scene often exceeded the recommendations, while the time taken to transport them to the hospital tended to be within the recommendations.
Introdução: A qualidade e rapidez do socorro pré-hospitalar à pessoa vítima de trauma major é vital para diminuir a sua elevada mortalidade. Contudo, desconhece-se a efetividade desta resposta em Portugal. O objetivo deste estudo foi analisar os tempos de resposta e as intervenções realizadas às vítimas de trauma major na região centro de Portugal. Métodos: Estudo retrospetivo, descritivo, utilizando os registos clínicos de 2022 dos meios diferenciados do Instituto Nacional de Emergência Médica. Casos de óbito pré-chegada ao hospital e outras situações de não transporte foram excluídos. Determinaram-se cinco tempos, entre os quais o tempo de resposta (T1, decorrente entre acionamento e chegada ao local), o tempo no local (T2) e o tempo de transporte (T5, intervalo entre a decisão de transporte e a chegada ao serviço de urgência). Foram calculadas médias e medidas de dispersão para cada meio, bem como a proporção de casos em que foram cumpridos os tempos recomendados nacional e internacionalmente. Avaliou-se também a frequência de registo de seis intervenções chave. Resultados: Dos 3366 registos, eliminaram-se 602 (384 por óbito), resultando em 2764 casos [suporte imediato de vida (SIV) = 36,0%, viaturas médicas de emergência e reanimação (VMER) = 62,2%, helicóptero de emergência médica (HEM) = 1,8%]. Num elevado número de registos não foi possível determinar tempos de socorro: por exemplo, o tempo de transporte (T5) foi determinável em apenas 29%, 13%, e 8% dos casos, respetivamente para SIV, VMER e HEM. O tempo recomendado para a estabilização (T2 ≤ 20 min), foi cumprido em 19,8% (SIV), 36,5% (VMER), e 18,2% (HEM) dos regis- tos. Já o tempo de transporte (T5 ≤ 45 min) foi cumprido em 80,0% (SIV), 93,1% (VMER) e 75,0% (HEM) dos registos (avaliáveis). A administração de analgesia (42% na SIV) e as medidas de prevenção de hipotermia (23,5% na SIV) foram as intervenções mais registadas. Conclusão: Observaram-se muitos status omissos e falta de informação nos registos, sobretudo na VMER e HEM. De acordo com os registos, o tempo no local superou frequentemente as recomendações, enquanto o tempo de transporte tende a estar dentro das normas.

BACKGROUND: A severely injured patient needs fast transportation to a hospital that can provide definitive care. In Norway, approximately 20% of the population live in rural areas. Primary care doctors (PCDs) play an important role in prehospital trauma care. The aim of this study was to investigate how variations in PCD call-outs to severe trauma incidents in Norway were associated with rural-urban settings and time factors.
METHODS: In this study on severe trauma patients admitted to Norwegian hospitals from 2012 to 2018, we linked data from four official Norwegian registries. Through this, we investigated the call-out responses of PCDs to severe trauma incidents. In multivariable log-binomial regression models, we investigated whether factors related to rural-urban settings and time factors were associated with PCD call-outs.
RESULTS: There was a significantly higher probability of PCD call-outs to severe trauma incidents in the municipalities in the four most rural centrality categories compared to the most urban category. The largest difference in adjusted relative risk (95% confidence interval (CI)) was 2.08 (1.27-3.41) for centrality category four. PCDs had a significantly higher proportion of call-outs in the Western (RR = 1.46 (1.23-1.73)) and Central Norway (RR = 1.30 (1.08-1.58)) Regional Health Authority areas compared to in the South-Eastern area. We observed a large variation (0.47 to 4.71) in call-out rates to severe trauma incidents per 100,000 inhabitants per year across the 16 Emergency Medical Communication Centre areas in Norway.
CONCLUSIONS: Centrality affects the proportion of PCD call-outs to severe trauma incidents, and call-out rates were higher in rural than in urban areas. We found no significant difference in call-out rates according to time factors. Possible consequences of these findings should be further investigated.

BACKGROUND: Advanced Trauma Life Support was originated mainly to train doctors who don\'t manage trauma on a regular basis, including junior doctors as it prepares them more efficiently and effectively for treating and managing trauma patients. This study was conducted to study knowledge, attitude and practice of advanced trauma life support protocol among house-officers in Khartoum state hospitals, Sudan 2023.
METHODS: This is a cross-sectional descriptive health facility based study conducted in Bahri Teaching Hospital, Omdurman Teaching Hospital and Ibrahim Malik teaching hospital, Khartoum state, Sudan. Data of 151 House-officers of all nationality working in Khartoum state hospitals was collected using a simple random technique, filling questionnaire that was designed especially for this study. Comparison between different variables by Chi-square test and statistical significance difference at P value < 0.05 was done.
RESULTS: A total of 151 house officers were included in the study. 49% aged between 20 and 25 years, females were the majority 56.3%. About 41.1% have took ATLS course before. 55.21% of the study participants didn\'t take the course because it was not available, while 35.42% because it was expensive and 29.17% referred it to their busy lifestyle. 91% of the study population think that ATLS course should be compulsory and 85% think that the ATLS protocol should be recommended to both junior and senior doctors. 77% of the study participants stated that their seniors teaching skills affect how they apply ATLS.
CONCLUSIONS: Overall junior doctors at Khartoum state hospitals demonstrated a positive attitude towards ATLS, but they showed poor knowledge regarding the topic. It\'s advised that an earlier training program is introduced by incorporating ATLS course to be part of all final year medical school\'s curriculum.

BACKGROUND: Advanced Trauma Life Support (ATLS) is the gold standard of initial assessment of trauma patients and therefore a widely used training program for medical professionals. Practical application of the knowledge taught can be challenging for medical students and inexperienced clinicians. Simulation-based training, including virtual reality (VR), has proven to be a valuable adjunct to real-world experiences in trauma education. Previous studies have demonstrated the effectiveness of VR simulations for surgical and technical skills training. However, there is limited evidence on VR simulation training specifically for trauma education, particularly within the ATLS curriculum. The purpose of this pilot study is to evaluate the feasibility, effectiveness, and acceptance of using a fully immersive VR trauma simulation to prepare medical students for the ATLS course.
METHODS: This was a prospective randomised controlled pilot study on a convenience sample of advanced medical students (n = 56; intervention group with adjunct training using a commercially available semi-automated trauma VR simulation, n = 28, vs control group, n = 28) taking part in the ATLS course of the Military Physician Officer School. Feasibility was assessed by evaluating factors related to technical factors of the VR training (e.g. rate of interruptions and premature termination). Objective and subjective effectiveness was assessed using confidence ratings at four pre-specified points in the curriculum, validated surveys, clinical scenario scores, multiple choice knowledge tests, and ATLS final clinical scenario and course pass rates. Acceptance was measured using validated instruments to assess variables of media use (Technology acceptance, usability, presence and immersion, workload, and user satisfaction).
RESULTS: The feasibility assessment demonstrated that only one premature termination occurred and that all remaining participants in the intervention group correctly stabilised the patient. No significant differences between the two groups in terms of objective effectiveness were observed (p = 0.832 and p = 0.237 for the pretest and final knowledge test, respectively; p = 0.485 for the pass rates for the final clinical scenario on the first attempt; all participants passed the ATLS course). In terms of subjective effectiveness, the authors found significantly improved confidence post-VR intervention (p < .001) in providing emergency care using the ATLS principles. Perceived usefulness in the TEI was stated with a mean of 4 (SD 0.8; range 0-5). Overall acceptance and usability of the VR simulation was rated as positive (System Usability Scale total score mean 79.4 (SD 11.3, range 0-100).
CONCLUSIONS: The findings of this prospective pilot study indicate the potential of using VR trauma simulations as a feasible and acceptable supplementary tool for the ATLS training course. Where objective effectiveness regarding test and scenario scores remained unchanged, subjective effectiveness demonstrated improvement. Future research should focus on identifying specific scenarios and domains where VR can outperform or enhance traditional learning methods in trauma simulation.

BACKGROUND: Bullfighting festivals are attributed to the cultural idiosyncrasies of the Ibero-American people, posing an extreme risk to the physical integrity of the participants. Spain is considered the country with the highest number of bull-related celebrations worldwide and, therefore, with the highest number of patients injured by bullfighting trauma treated, thus justifying a public health problem. The generalities associated with this type of trauma define the people injured as polytraumatised patients. In addition, it is important to know the kinematics of the injuries and their specific characteristics, in order to implement quality medical-surgical care.
METHODS: scientific review of the literature to promote a comprehensive guide for the medical-surgical management of patients injured by bullfighting trauma.
RESULTS: We described the guidelines to standardise protocols for in-hospital approach of patients injured by bullfighting trauma.
CONCLUSIONS: Bullfighting trauma is considered a real health problem in the emergency departments of the ibero-Americans countries, especially in Spain, where bullfighting is part of the national culture. The inherent characteristics of these animals cause injuries with special aspects, so it is important to know the generalities of bullfighting trauma. Because of the multidisciplinary approach, this guidelines are adressed to all healthcare providers involved in the management of these patients. It is essential to establish particular initial care for this type of injury, specific therapeutic action and follow-up based on the medical-surgical management of the trauma patient in order to reduce the associated morbidity and mortality.

BACKGROUND: The course in Primary Care in Pediatric Trauma (ATIP in Spanish) has been taught in Spain since 1997, and there are currently 9 accredited training centers. Care of polytraumatized pediatric patients often takes place in an environment conducive to errors resulting from forgetfulness, which is why checklists - mnemonic tools widely used in industry and medicine - are particularly useful to avoid such errors. Although several checklists exist for pediatric trauma care, none have been developed within the setting of our course.
METHODS: The criteria for being selected as an expert in Primary Care in Pediatric Trauma were agreed upon with the scientific polytrauma committee of the Spanish Pediatric Surgery Society. The items that make up the checklist were obtained from a review of the literature and consultation with selected experts, using the Delphi Technique.
RESULTS: 10 experts representing the 9 groups or training centers in Primary Care in Pediatric Trauma were selected, and a 28-item checklist was drawn up in accordance with their design recommendations.
CONCLUSIONS: With the consensus of all the groups, a checklist for the treatment of polytraumatized pediatric patients was drawn up using the Delphi Technique, an essential requirement for the dissemination of this checklist, which should be adapted and validated for use in each healthcare center.
BACKGROUND: El curso de Asistencia Inicial al Trauma Pediátrico se imparte en España desde 1997, existiendo en la actualidad 9 centros formadores acreditados. La asistencia al paciente pediátrico politraumatizado se produce muchas veces en un ambiente proclive al error por olvido, por lo que las listas de verificación, como herramientas mnemotécnicas de amplia difusión en la industria y en medicina, serían especialmente útiles para evitarlos. Aunque existen varias listas de verificación para la asistencia al traumatismo pediátrico, ninguna se ha desarrollado en el entorno de nuestro curso.
METHODS: Se acordaron los criterios para ser seleccionado como experto en Asistencia Inicial al Trauma Pediátrico con la comisión científica de politrauma de la Sociedad Española de Cirugía Pediátrica. Los ítems para formar la lista de verificación se obtuvieron a partir de una revisión bibliográfica y de la consulta a los expertos seleccionados, empleando un método Delphi.
RESULTS: Se seleccionaron 10 expertos que representan los 9 grupos o centros formadores en Asistencia Inicial al Trauma Pediátrico y se elaboró una lista de verificación con 28 ítems, siguiendo sus recomendaciones de diseño.
CONCLUSIONS: Se diseñó una lista de verificación para el manejo del paciente pediátrico politraumatizado, con el consenso de todos los grupos empleando un método Delphi, requisito fundamental para facilitar la difusión de esta lista. Sería preciso adaptar y validar dicha lista para su uso en cada centro asistencial.

BACKGROUND: Accidental hypothermia is common in all trauma patients and contributes to the lethal diamond, increasing both morbidity and mortality. In hypotensive shock, fluid resuscitation is recommended using fluids with a temperature of 37-42°, as fluid temperature can decrease the patient\'s body temperature. In Sweden, virtually all prehospital services use preheated fluids. The aim of the present study was to investigate how the temperature of preheated infusion fluids is affected by the ambient temperatures and flow rates relevant for prehospital emergency care.
METHODS: In this experimental simulation study, temperature changes in crystalloids preheated to 39 °C were evaluated. The fluid temperature changes were measured both in the infusion bag and at the patient end of the infusion system. Measurements were conducted in conditions relevant to prehospital emergency care, with ambient temperatures varying between - 4 and 28 °C and flow rates of 1000 ml/h and 6000 ml/h, through an uninsulated infusion set at a length of 175 cm.
RESULTS: The flow rate and ambient temperature affected the temperature in the infusion fluid both in the infusion bag and at the patient end of the system. A lower ambient temperature and lower flow rate were both associated with a greater temperature loss in the infusion fluid.
CONCLUSIONS: This study shows that both a high infusion rate and a high ambient temperature are needed if an infusion fluid preheated to 39 °C is to remain above 37 °C when it reaches the patient using a 175-cm-long uninsulated infusion set. It is apparent that the lower the ambient temperature, the higher the flow rate needs to be to limit temperature loss of the fluid.
