Comparing outcomes in patients with exsanguinating injuries: an Eastern Association for the Surgery of Trauma (EAST), multicenter, international trial evaluating prioritization of circulation over intubation (CAB over ABC).

INTRODUCTION: Hemorrhage is a major cause of preventable trauma deaths, and the ABC approach is widely used during the primary survey. We hypothesize that prioritizing circulation over intubation (CAB) can improve outcomes in patients with exsanguinating injuries. METHODS: A prospective observational study involving international trauma centers was conducted. Patients with systolic blood pressure below 90 who were intubated within 30 min of arrival were included. Prioritizing circulation (CAB) was defined as delaying intubation until blood products were started, and/or bleeding control was performed before securing the airway. Demographics, clinical data, and outcomes were recorded. RESULTS: The study included 278 eligible patients, with 61.5% falling within the "CAB" cohort and 38.5% in the "ABC" cohort. Demographic and disease characteristics, including age, sex, ISS, use of blood products, and other relevant factors, exhibited comparable distributions between the two cohorts. The CAB group had a higher proportion of penetrating injuries and more patients receiving intubation in the operating room. Notably, patients in the CAB group demonstrated higher GCS scores, lower SBP values before intubation but higher after intubation, and a significantly lower incidence of cardiac arrest and post-intubation hypotension. Key outcomes revealed significantly lower 24-hour mortality in the CAB group (11.1% vs. 69.2%), a lower rate of renal failure, and a higher rate of ARDS. Multivariable logistic regression models showed a 91% reduction in the odds of mortality within 24 h and an 89% reduction at 30 days for the CAB cohort compared to the ABC cohort. These findings suggest that prioritizing circulation before intubation is associated with improved outcomes in patients with exsanguinating injuries. CONCLUSION: Post-intubation hypotension is observed to be correlated with worse outcomes. The consideration of prioritizing circulation over intubation in patients with exsanguinating injuries, allowing for resuscitation, or bleeding control, appears to be associated with potential improvements in survival. Emphasizing the importance of circulation and resuscitation is crucial, and this approach might offer benefits for various bleeding-related conditions.

[Orthopedics and trauma surgery in the digital age]. / Orthopädie und Unfallchirurgie im digitalen Zeitalter.

BACKGROUND: Digital transformation is shaping the future of orthopedics and trauma surgery. Telemedicine, digital health applications, electronic patient records and artificial intelligence play a central role in this. These technologies have the potential to improve medical care, enable individualized patient treatment plans and reduce the burden on the treatment process. However, there are currently challenges in the areas of infrastructure, regulation, reimbursement and data protection. REALISING THE TRANSFORMATION: Effective transformation requires a deep understanding of both technology and clinical practice. Orthopedic and trauma surgeons need to take a leadership role by actively engaging with new technologies, designing new treatment processes and enhancing their medical skills with digital and AI competencies. The integration of digital skills into medical education and specialist training will be crucial for actively shaping the digital transformation and exploiting its full potential.

A menudo está asociado a lesiones potencialmente mortales, por esta razón, es fundamental conocer los principios de diagnóstico y tratamiento, así como los protocolos de atención inicial de los pacientes politraumatizados. Método: Reportamos el caso de un paciente masculino de 47 años con trauma anorrectal contuso con compromiso del esfínter anal interno y externo, tratado con reparación primaria del complejo esfinteriano con técnica de overlapping, rafia de la mucosa, submucosa y muscular del recto. A los 12 meses presenta buena evolución sin incontinencia anal. Conclusión: El tratamiento del trauma rectal, basado en el dogma de las 4 D (desbridamiento, derivación fecal, drenaje presacro, lavado distal) fue exitoso. La técnica de overlapping para la lesión esfinteriana fue simple y efectiva para la reconstrucción anatómica y funcional. (AU)

Introduction: Anorectal trauma is a rare cause of consultation to the Emergency Department, with an incidence of 1 to 3%. It is often associated with life-threatening injuries, so it is essential to know the principles of diagnosis and treatment, as well as the initial care protocols for the polytrau-matized patient. Methods: We present the case of a 47-year-old man with a blunt anorectal trauma involving the internal and external anal sphincter, treated with primary overlapping repair of the sphincter complex and suturing of the rectal wall. At 12 months the patient presents good outcome, without anal incontinence. Conclusion: The treatment of rectal trauma, based on the 4 D ́s dogma (debridement, fecal diversion, presacral drainage, distal rectal washout lavage) was successful. Repair of the overlapping sphincter injury was simple and effective for anatomical and functional reconstruction. (AU)

European society for trauma and emergency surgery member-identified research priorities in emergency surgery: a roadmap for future clinical research opportunities.

BACKGROUND: European Society for Trauma and Emergency Surgery (ESTES) is the European community of clinicians providing care to the injured and critically ill surgical patient. ESTES has several interlinked missions - (1) the promotion of optimal emergency surgical care through networked advocacy, (2) promulgation of relevant clinical cognitive and technical skills, and (3) the advancement of scientific inquiry that closes knowledge gaps, iteratively improves upon surgical and perioperative practice, and guides decision-making rooted in scientific evidence. Faced with multitudinous opportunities for clinical research, ESTES undertook an exercise to determine member priorities for surgical research in the short-to-medium term; these research priorities were presented to a panel of experts to inform a 'road map' narrative review which anchored these research priorities in the contemporary surgical literature. METHODS: Individual ESTES members in active emergency surgery practice were polled as a representative sample of end-users and were asked to rank potential areas of future research according to their personal perceptions of priority. Using the modified eDelphi method, an invited panel of ESTES-associated experts in academic emergency surgery then crafted a narrative review highlighting potential research priorities for the Society. RESULTS: Seventy-two responding ESTES members from 23 countries provided feedback to guide the modified eDelphi expert consensus narrative review. Experts then crafted evidence-based mini-reviews highlighting knowledge gaps and areas of interest for future clinical research in emergency surgery: timing of surgery, inter-hospital transfer, diagnostic imaging in emergency surgery, the role of minimally-invasive surgical techniques and Enhanced Recovery After Surgery (ERAS) protocols, patient-reported outcome measures, risk-stratification methods, disparities in access to care, geriatric outcomes, data registry and snapshot audit evaluations, emerging technologies interrogation, and the delivery and benchmarking of emergency surgical training. CONCLUSIONS: This manuscript presents the priorities for future clinical research in academic emergency surgery as determined by a sample of the membership of ESTES. While the precise basis for prioritization was not evident, it may be anchored in disease prevalence, controversy around aspects of current patient care, or indeed the identification of a knowledge gap. These expert-crafted evidence-based mini-reviews provide useful insights that may guide the direction of future academic emergency surgery research efforts.

[Feedback on a dedicated circuit for unscheduled surgery]. / Retour d'expérience sur un circuit dédié pour la chirurgie non programmée.

A few months ago, the Pitié-Salpêtrière orthopedics department set up a specific circuit for trauma patients. Here's a look back at this innovation, which highlights the importance of multidisciplinary work for patients.

The Golden Hour of Casualty Care: Rapid Handoff to Surgical Team is Associated With Improved Survival in War-injured US Service Members.

OBJECTIVE: To examine time from injury to initiation of surgical care and association with survival in US military casualties. BACKGROUND: Although the advantage of trauma care within the "golden hour" after an injury is generally accepted, evidence is scarce. METHODS: This retrospective, population-based cohort study included US military casualties injured in Afghanistan and Iraq, January 2007 to December 2015, alive at initial request for evacuation with maximum abbreviated injury scale scores ≥2 and documented 30-day survival status after injury. Interventions: (1) handoff alive to the surgical team, and (2) initiation of first surgery were analyzed as time-dependent covariates (elapsed time from injury) using sequential Cox proportional hazards regression to assess how intervention timing might affect mortality. Covariates included age, injury year, and injury severity. RESULTS: Among 5269 patients (median age, 24 years; 97% males; and 68% battle-injured), 728 died within 30 days of injury, 68% within 1 hour, and 90% within 4 hours. Only handoffs within 1 hour of injury and the resultant timely initiation of emergency surgery (adjusted also for prior advanced resuscitative interventions) were significantly associated with reduced 24-hour mortality compared with more delayed surgical care (adjusted hazard ratios: 0.34; 95% CI: 0.14-0.82; P = 0.02; and 0.40; 95% CI: 0.20-0.81; P = 0.01, respectively). In-hospital waits for surgery (mean: 1.1 hours; 95% CI; 1.0-1.2) scarcely contributed ( P = 0.67). CONCLUSIONS: Rapid handoff to the surgical team within 1 hour of injury may reduce mortality by 66% in US military casualties. In the subgroup of casualties with indications for emergency surgery, rapid handoff with timely surgical intervention may reduce mortality by 60%. To inform future research and trauma system planning, findings are pivotal.

Reportable infections following colon surgery in a large public healthcare system in New York City: The consequences of being a level 1 trauma center.

OBJECTIVES: To examine differences in risk factors and outcomes of patients undergoing colon surgery in level 1 trauma centers versus other hospitals and to investigate the potential financial impact of these reportable infections. DESIGN: Retrospective cohort study between 2015 and 2022. SETTING: Large public healthcare system in New York City. PARTICIPANTS: All patients undergoing colon surgery; comparisons were made between (1) all patients undergoing colon surgery at the level 1 trauma centers versus patients at the other hospitals and (2) the nontrauma and trauma patients at the level 1 trauma centers versus the nontrauma patients at other hospitals. RESULTS: Of 5,217 colon surgeries reported, 3,531 were at level 1 trauma centers and 1686 at other hospitals. Patients at level 1 trauma centers had significantly increased American Society of Anesthesiology (ASA) scores, durations of surgery, rates of delayed wound closure, and rates of class 4 wounds, resulting in higher SIRs (1.1 ± 0.15 vs 0.75 ± 0.18; P = .0007) compared to the other hospitals. Compared to the nontrauma patients at the other hospitals, both the nontrauma and trauma patients at the level 1 trauma centers had higher ASA scores, rates of delayed wound closure, and of class 4 wounds. The SIRs of the nontrauma patients (1.16 ± 1.29; P = .008) and trauma patients (1.26 ± 2.69; P = .066) at the level 1 trauma center were higher than the SIRs of nontrauma patients in the other hospitals (0.65 ± 1.18). CONCLUSIONS: Patients undergoing colon surgery at level 1 trauma centers had increased complexity of surgery compared to the patients in other hospitals. Until there is appropriate adjustment for these risk factors, the use of infections following colon surgery as a reportable quality measure should be re-evaluated.

American Association for the Surgery of Trauma/American College of Surgeons Committee on Trauma: Clinical protocol for damage-control resuscitation for the adult trauma patient.

ABSTRACT: Damage-control resuscitation in the care of critically injured trauma patients aims to limit blood loss and prevent and treat coagulopathy by combining early definitive hemorrhage control, hypotensive resuscitation, and early and balanced use of blood products (hemostatic resuscitation) and the use of other hemostatic agents. This clinical protocol has been developed to provide evidence-based recommendations for optimal damage-control resuscitation in the care of trauma patients with hemorrhage.

Unique Usages of Dehydrated Human Amnion Chorion Membrane Allografts in Dermatology.

Dehydrated human amnion chorion membrane (dHACM) allografts are synthetic skin substitutes derived from placental tissue. dHACM allografts are used for replacing lost or damaged dermal tissue, as they contain many of the components found within the extracellular matrix that are beneficial in wound healing. Common uses of dHACM allografts include the healing of diabetic and non-diabetic foot and leg ulcers, decubitus ulcers, and wounds following debridement. While these grafts have been proven to be beneficial in other disciplines of medicine, their potential for use in the field of dermatology is emerging. Current clinical cases and research have shown dHACM allografts to be beneficial in repairing damaged tissue due to dermatologic conditions. They could play a role in the treatment of conditions causing chronic wounds, including dermal scarring or loss, and the repair of fragile skin. Examples of dHACM allograft use in dermatology include cases of pyoderma gangrenosum, Netherton syndrome, and wound healing with Mohs micrographic surgery. This literature review explores the efficacy of using dHACM allografts for the treatment of healing wounds within the field of dermatology.

Injectable tissue prosthesis for instantaneous closed-loop rehabilitation.

To construct tissue-like prosthetic materials, soft electroactive hydrogels are the best candidate owing to their physiological mechanical modulus, low electrical resistance and bidirectional stimulating and recording capability of electrophysiological signals from biological tissues1,2. Nevertheless, until now, bioelectronic devices for such prostheses have been patch type, which cannot be applied onto rough, narrow or deep tissue surfaces3-5. Here we present an injectable tissue prosthesis with instantaneous bidirectional electrical conduction in the neuromuscular system. The soft and injectable prosthesis is composed of a biocompatible hydrogel with unique phenylborate-mediated multiple crosslinking, such as irreversible yet freely rearrangeable biphenyl bonds and reversible coordinate bonds with conductive gold nanoparticles formed in situ by cross-coupling. Closed-loop robot-assisted rehabilitation by injecting this prosthetic material is successfully demonstrated in the early stage of severe muscle injury in rats, and accelerated tissue repair is achieved in the later stage.

Outcome of severely injured patients in a unique trauma system with 24/7 double trauma surgeon on-call service.

BACKGROUND: The presence of in-house attending trauma surgeons has improved efficiency of processes in the treatment of polytrauma patients. However, literature remains equivocal regarding the influence of the presence of in-house attendings on mortality. In our hospital there is a double trauma surgeon on-call system. In this system an in-house trauma surgeon is 24/7 backed up by a second trauma surgeon to assist with urgent surgery or multiple casualties. The aim of this study was to evaluate outcome in severely injured patients in this unique trauma system. METHODS: From 2014 to 2021, a prospective population-based cohort consisting of consecutive polytrauma patients aged ≥ 15 years requiring both urgent surgery (≤ 24h) and admission to Intensive Care Unit (ICU) was investigated. Demographics, treatment, outcome parameters and pre- and in-hospital transfer times were analyzed. RESULTS: Three hundred thirteen patients with a median age of 44 years (71% male), and median Injury Severity Score (ISS) of 33 were included. Mortality rate was 19% (68% due to traumatic brain injury). All patients stayed ≤ 32 min in ED before transport to either CT or OR. Fifty-one percent of patients who needed damage control surgery (DCS) had a more deranged physiology, needed more blood products, were more quickly in OR with shorter time in OR, than patients with early definitive care (EDC). There was no difference in mortality rate between DCS and EDC patients. Fifty-six percent of patients had surgery during off-hours. There was no difference in outcome between patients who had surgery during daytime and during off-hours. Death could possibly have been prevented in 1 exsanguinating patient (1.7%). CONCLUSION: In this cohort of severely injured patients in need of urgent surgery and ICU support it was demonstrated that surgical decision making was swift and accurate with low preventable death rates. 24/7 Physical presence of a dedicated trauma team has likely contributed to these good outcomes.

Parkland Trauma Index of Mortality in Orthopaedic Trauma Patients: An Initial Report.

OBJECTIVES: The extent and timing of surgery in severely injured patients remains an unsolved problem in orthopaedic trauma. Different laboratory values or scores have been used to try to predict mortality and estimate physiological reserve. The Parkland Trauma Index of Mortality (PTIM) has been validated as an electronic medical record-integrated algorithm to help with operative timing in trauma patients. The aim of this study was to report our initial experience with PTIM and how it relates to other scores. METHODS: A retrospective chart review of level 1 and level 2 trauma patients admitted to our institution between December 2020 and November 2022 was conducted. Patients scored with PTIM with orthopaedic injuries were included in this study. Exclusion criteria were patients younger than 18 years. RESULTS: Seven hundred seventy-four patients (246 female patients) with a median age of 40.5 (18-101) were included. Mortality was 3.1%. Patients in the PTIM high-risk category (≥0.5) had a 20% mortality rate. The median PTIM was 0.075 (0-0.89) and the median Injury Severity Score (ISS) was 9.0 (1-59). PTIM (P < 0.001) and ISS (P < 0.001) were significantly lower in surviving patients. PTIM was mentioned in 7.6% of cases, and in 1.7% of cases, providers indicated an action in response to the PTIM. PTIM and ISS were significantly higher in patients with documented PTIM. CONCLUSION: PTIM is better at predicting mortality compared with ISS. Our low rate of PTIM documentation in provider notes highlights the challenges of implementing a new algorithm. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

The Bidirectionality of Global Surgical Research: The Utility of the Malawi Trauma Score in the United States Trauma Population.

INTRODUCTION: Trauma scoring systems provide valuable risk stratification of injured patients. Trauma scoring systems developed in resource-limited settings, such as the Malawi Trauma Score (MTS), are based on readily available clinical information. This study sought to test the performance of the MTS in a United States trauma population. MATERIALS AND METHODS: We analyzed the United States National Trauma Data Bank during 2017-2020. MTS uses alertness score: alert, responds to verbal or painful stimuli, or unresponsive (AVPU), age, sex, presence of a radial pulse, and primary anatomic injury location. MTS and an age-adjusted version reflective of the US age distribution, was evaluated for its performance in predicting crude mortality in the National Trauma Data Bank using receiver operating characteristic analysis. We utilized logistic regression to model the odds ratio of death at a particular MTS cutoff. RESULTS: A total of 3,833,929 patients were included. The mean age was 49.3 y (sandard deviation 24.4), with a male preponderance (61.1%). Crude mortality was 3.4% (n = 131,452/3,833,929). The area under the curve for the MTS in predicting mortality was 0.87 (95% CI 0.87, 0.88). The area under the curve for a cutoff of 15 was 0.83 (95% CI 0.83, 0.83). An MTS of 15 higher had an odds ratio of death of 46.5 (95% CI 45.9, 47.1), compared to those with a score of 14 or lower. CONCLUSIONS: MTS has excellent performance as a predictor of mortality in a US trauma population. MTS is simple to calculate and can be estimated in the prehospital setting or the emergency department. Consequently, it may have utility as a triage tool in both high-income trauma systems and resource-limited settings.

Pediatric trauma surgery in Iraq and Afghanistan: Mortality, indicators, and most common operating room interventions from 2007 to 2016.

BACKGROUND: The wars in Afghanistan and Iraq produced thousands of pediatric casualties, using substantial military medical resources. We sought to describe characteristics of pediatric casualties who underwent operative intervention in Iraq and Afghanistan. METHODS: This is a retrospective analysis of pediatric casualties treated by US Forces in the Department of Defense Trauma Registry with at least one operative intervention during their course. We report descriptive, inferential statistics, and multivariable modeling to assess associations for receiving an operative intervention and survival. We excluded casualties who died on arrival to the emergency department. RESULTS: During the study period, there were a total of 3,439 children in the Department of Defense Trauma Registry, of which 3,388 met inclusion criteria. Of those, 2,538 (75%) required at least 1 operative intervention totaling 13,824 (median, 4; interquartile range, 2-7; range, 1-57). Compared with nonoperative casualties, operative casualties were older and male and had a higher proportion of explosive and firearm injuries, higher median composite injury severity scores, higher overall blood product administration, and longer intensive care hospitalizations. The most common operative procedures were related to abdominal, musculoskeletal, and neurosurgical trauma; burn management; and head and neck. When adjusting for confounders, older age (unit odds ratio, 1.04; 1.02-1.06), receiving a massive transfusion during their initial 24 hours (6.86, 4.43-10.62), explosive injuries (1.43, 1.17-1.81), firearm injuries (1.94, 1.47-2.55), and age-adjusted tachycardia (1.45, 1.20-1.75) were all associated with going to the operating room. Survival to discharge on initial hospitalization was higher in the operative cohort (95% vs. 82%, p < 0.001). When adjusting for confounders, operative intervention was associated with improved mortality (odds ratio, 7.43; 5.15-10.72). CONCLUSION: Most children treated in US military/coalition treatment facilities required at least one operative intervention. Several preoperative descriptors were associated with casualties' likelihood of operative interventions. Operative management was associated with improved mortality. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Chronic axillary wounds in cats: what do we know and how should we manage them?

PRACTICAL RELEVANCE: Axillary wounds most often occur in outdoor cats that wear a collar, typically after having been missing. These wounds are commonly chronic and indolent in nature, and although there is so far no consensus on an explanation for this, it is likely that there are several factors involved. CLINICAL CHALLENGES: Axillary wounds are often difficult to manage due to the frequent presence of infection, their histopathological characteristics and their location, where there is excessive tension and movement of the axillary tissues. Initial surgical treatment has a high reported incidence of failure and complications in the literature, with wound breakdown reported most commonly. Giving due consideration to the difficulties of managing these wounds, however, will help practitioners to decrease the occurrence of complications and the need for multiple procedures, and therefore improve the outcome. EQUIPMENT: Initial approach and surgical management can be achieved using standard medical equipment and surgical kit available to general practitioners. EVIDENCE BASE: This review discusses the surgical techniques reported in the literature to have successfully treated chronic axillary wounds and recommendations are also provided based on the authors' clinical experience.

Hospitalization costs of injury in elderly population in China: a quantile regression analysis.

BACKGROUND: Trauma in the elderly is gradually growing more prevalent as the aging population increases over time. The purpose of this study is to assess hospitalization costs of the elderly trauma population and analyze the association between those costs and the features of the elderly trauma population. METHODS: In a retrospective analysis, data on trauma patients over 65 who were admitted to the hospital for the first time due to trauma between January 2017 and March 2022 was collected from a tertiary comprehensive hospital in Baotou. We calculated and analyzed the hospitalization cost components. According to various therapeutic approaches, trauma patients were divided into two subgroups: non-surgical patients (1320 cases) and surgical patients (387 cases). Quantile regression was used to evaluate the relationship between trauma patients and hospitalization costs. RESULTS: This study comprised 1707 trauma patients in total. Mean total hospitalization costs per patient were ¥20,741. Patients with transportation accidents incurred the highest expenditures among those with external causes of trauma, with a mean hospitalization cost of ¥24,918, followed by patients with falls at ¥19,809 on average. Hospitalization costs were dominated by medicine costs (¥7,182 per capita). According to the quantile regression results, all trauma patients' hospitalization costs were considerably increased by length of stay, surgery, the injury severity score (16-24), multimorbidity, thorax injury, and blood transfusion. For non-surgical patients, length of stay, multimorbidity, and the injury severity score (16-24) were all substantially linked to higher hospitalization costs. For surgical patients, length of stay, injury severity score (16-24), and hip and thigh injuries were significantly associated with greater hospitalization costs. CONCLUSIONS: Using quantile regression to identify factors associated with hospitalization costs could be helpful for addressing the burden of injury in the elderly population. Policymakers may find these findings to be insightful in lowering hospitalization costs related to injury in the elderly population.
