Complications and failure rate of splenic artery angioembolization following blunt splenic trauma: A systematic review.

BACKGROUND: Over recent decades, splenic angioembolization (SAE) as an adjunct to non-operative management (NOM) has emerged as a prominent intervention for patients with blunt splenic injuries (BSI). SAE improves patient outcomes, salvages the spleen, and averts complications associated with splenectomy. This systematic review aimed to evaluate the failure rate and complications related to SAE in patients with BSI. METHODS: A systematic literature search (PubMed, SCOPUS, and Cochrane Library) focused on studies detailing splenic angioembolization in blunt trauma cases. Articles that fulfilled the predetermined inclusion criteria were included. This review examined the indications, outcomes, failure rate, and complications of SAE. RESULTS: Among 599 identified articles, 33 met the inclusion criteria. These comprised 29 retrospective studies, three prospective studies, and one randomized control trial. The analysis encompassed 25,521 patients admitted with BSI and 3,835 patients who underwent SAE. The overall failure rate of SAE was 5.3 %. Major complications predominantly were rebleeding (4.8 %), infarction (4.6 %), and abscess formation (4 %). Minor complications were fever (18.4 %), pleural effusion (13.1 %), and coil migration (3.9 %). Other complications included splenic atrophy, splenic cyst, hematoma, and access site complications such as splenic/femoral dissection. Overall, post embolization mortality was 0.08 %. CONCLUSION: SAE is a valuable adjunct in managing BSI, with a low failure rate. However, this treatment modality is not without the risk of potentially serious complications.

Strategies to prevent blood loss and reduce transfusion in emergency general surgery, WSES-AAST consensus paper.

Emergency general surgeons often provide care to severely ill patients requiring surgical interventions and intensive support. One of the primary drivers of morbidity and mortality is perioperative bleeding. In general, when addressing life threatening haemorrhage, blood transfusion can become an essential part of overall resuscitation. However, under all circumstances, indications for blood transfusion must be accurately evaluated. When patients decline blood transfusions, regardless of the reason, surgeons should aim to provide optimal care and respect and accommodate each patient's values and target the best outcome possible given the patient's desires and his/her clinical condition. The aim of this position paper was to perform a review of the existing literature and to provide comprehensive recommendations on organizational, surgical, anaesthetic, and haemostatic strategies that can be used to provide optimal peri-operative blood management, reduce, or avoid blood transfusions and ultimately improve patient outcomes.

Machine learning models predict triage levels, massive transfusion protocol activation, and mortality in trauma utilizing patients hemodynamics on admission.

BACKGROUND: The effective management of trauma patients necessitates efficient triaging, timely activation of Massive Blood Transfusion Protocols (MTP), and accurate prediction of in-hospital outcomes. Machine learning (ML) algorithms have emerged as up-and-coming tools in the domains of optimizing triage decisions, improving intervention strategies, and predicting clinical outcomes, consistently outperforming traditional methodologies. This study aimed to develop, assess, and compare several ML models for the triaging processes, activation of MTP, and mortality prediction. METHODS: In a 10-year retrospective study, the predictive capabilities of seven ML models for trauma patients were systematically assessed using on-admission patients' hemodynamic data. All patient's data were randomly divided into training (80 %) and test (20 %) sets. Employing Python for data preprocessing, feature scaling, and model development, we evaluated K-Nearest Neighbors (KNN), Logistic Regression (LR), Decision Tree (DT), Support Vector Machines (SVM) with RBF kernels, Random Forest (RF), Extreme Gradient Boosting (XGBoost), and Artificial Neural Network (ANN). We employed various imputation techniques and addressed data imbalance through down-sampling, up-sampling, and synthetic minority for the over-sampling technique (SMOTE). Hyperparameter tuning, coupled with 5-fold cross-validation, was performed. The evaluation included essential metrics like sensitivity, specificity, F1 score, accuracy, Area Under the Receiver Operating Curve (AUC ROC), and Area Under the Precision recall Curve (AUC PR), ensuring robust predictive capability. RESULT: This study included 17,390 adult trauma patients; of them, 19.5 % (3385) were triaged at a critical level, 3.8 % (664) required MTP, and 7.7 % (1335) died in the hospital. The model's performance improved using imputation and balancing techniques. The overall models demonstrated notable performance metrics for predicting triage, MTP activation, and mortality with F1 scores of 0.75, 0.42, and 0.79, sensitivities of 0.73, 0.82, and 0.9, and AUC ROC values of 0.89, 0.95 and 0.99 respectively. CONCLUSION: Machine learning, especially RF models, effectively predicted trauma triage, MTP activation, and mortality. Featured critical hemodynamic variables include shock indices, systolic blood pressure, and mean arterial pressure. Therefore, models can do better than individual parameters for the early management and disposition of patients in the ED. Future research should focus on creating sensitive and interpretable models to enhance trauma care.

Mechanical versus manual cardiopulmonary resuscitation (CPR): an umbrella review of contemporary systematic reviews and more.

BACKGROUND: High-quality cardiopulmonary resuscitation (CPR) can restore spontaneous circulation (ROSC) and neurological function and save lives. We conducted an umbrella review, including previously published systematic reviews (SRs), that compared mechanical and manual CPR; after that, we performed a new SR of the original studies that were not included after the last published SR to provide a panoramic view of the existing evidence on the effectiveness of CPR methods. METHODS: PubMed, EMBASE, and Medline were searched, including English in-hospital (IHCA) and out-of-hospital cardiac arrest (OHCA) SRs, and comparing mechanical versus manual CPR. A Measurement Tool to Assess Systematic Reviews (AMSTAR-2) and GRADE were used to assess the quality of included SRs/studies. We included both IHCA and OHCA, which compared mechanical and manual CPR. We analyzed at least one of the outcomes of interest, including ROSC, survival to hospital admission, survival to hospital discharge, 30-day survival, and survival to hospital discharge with good neurological function. Furthermore, subgroup analyses were performed for age, gender, initial rhythm, arrest location, and type of CPR devices. RESULTS: We identified 249 potentially relevant records, of which 238 were excluded. Eleven SRs were analyzed in the Umbrella review (January 2014-March 2022). Furthermore, for a new, additional SR, we identified eight eligible studies (not included in any prior SR) for an in-depth analysis between April 1, 2021, and February 15, 2024. The higher chances of using mechanical CPR for male patients were significantly observed in three studies. Two studies showed that younger patients received more mechanical treatment than older patients. However, studies did not comment on the outcomes based on the patient's gender or age. Most SRs and studies were of low to moderate quality. The pooled findings did not show the superiority of mechanical compared to manual CPR except in a few selected subgroups. CONCLUSIONS: Given the significant heterogeneity and methodological limitations of the included studies and SRs, our findings do not provide definitive evidence to support the superiority of mechanical CPR over manual CPR. However, mechanical CPR can serve better where high-quality manual CPR cannot be performed in selected situations.

Presentations and management of hospitalized patients with upper extremity fractures at a level 1 trauma center: a 5-year observational study.

BACKGROUND: Upper extremity injuries (UEIs) are common in the emergency departments, yet they are under-reported in developing countries. This study examined the frequency, injury characteristics, and treatment approaches of upper extremity fractures (UEFs) among hospitalized trauma patients in a nationally representative population. METHODS: We conducted a retrospective, observational study including all the hospitalized patients with UEFs in the only level 1 trauma center in Qatar between July 2015 and August 2020. Comparative analyses were performed according to injury mechanisms, severity, and management approach. RESULTS: A total of 2,023 patients sustained UEIs with an average age of 34.4 ± 12.9 years, and 92% were males. Motor vehicle crashes (MVCs; 42.3%) were the primary cause of shoulder girdle injuries in 48.3% of cases. Fractures of the radius, ulna, and hands occurred in 30.8, 16.5 and 14.5%, respectively. Young adults were more involved in MVCs and motorcycle crashes (MCCs), while pedestrians who were typically older had a higher rate of humerus fractures. Patients with MCCs had a higher rate of clavicle and ulna fractures. Pedestrians were at risk of serious injuries, with a higher mean injury severity score and lower Glasgow Coma Scale. CONCLUSION: Most UEFs patients were young males and mainly affected by MVCs. Shoulder girdle, particularly clavicle and scapula/glenoid fractures, emerged as common injury sites. The study highlighted the potential risk of pedestrian injuries, as reflected in higher injury severity, concomitant injuries, and higher mortality. Future studies are needed to optimize preventive measures by incorporating insights into specific injury mechanisms and patterns of UEIs.

Pre- and post-implementation protocol for non-operative management of grade III-V splenic injuries: An observational study.

Background: Grade (III-V) blunt splenic injuries (BSI) in hemodynamically stable patients represent clinical challenges for successful non-operative management (NOM). In 2014, Our institution proposed a treatment protocol requiring splenic angiography and embolization for stable, intermediate, and high-grade BSI. It also included a follow-up CT scan for grade III BSI. We sought to assess the success rate of NOM in treating intermediate and high-grade BSI, following a standardized treatment protocol at a level 1 trauma center. Methods: An observational retrospective study was conducted. Data of patients with BSI from June 2011 to September 2019 were reviewed using the Qatar National Trauma Registry. Patients' demographics, CT scan and angiographic findings, grade of splenic injuries, and outcomes were analyzed. The pre- and post-implementation of treatment protocol periods were compared. Results: During the study period, a total of 552 hemodynamically stable patients with BSI were admitted, of which 240 had BSI with grade III to V. Eighty-one patients (33.8%) were admitted in the pre-protocol implementation period and 159 (66.2%) in the post-protocol implementation period. The NOM rate increased from 50.6% in the pre-protocol group to 65.6% in the post-protocol group (p = 0.02). In addition, failure of the conservative treatment did not significantly differ in the two periods, while the requirement for blood transfusion dropped from 64.2% to 45.9% (p = 0.007). The frequency of CT scan follow-up (55.3% vs. 16.3%, p = 0.001) and splenic arterial embolization (32.7% vs. 2.5%, p = 0.001) in NOM patients increased significantly in the post-protocol group compared to the pre-protocol group. Overall mortality was similar between the two periods. However, hospital and ICU length of stay and ventilatory days were higher in the post-protocol group. Conclusions: NOM is an effective and safe treatment option for grade III-V BSI patients. Using standardized treatment guidelines for intermediate-to high-grade splenic injuries could increase the success rate for NOM and limit unnecessary laparotomy. Moreover, angioembolization is a crucial adjunct to NOM that could improve the success rate.

Empirical Pyridostigmine in a Patient with Difficult Weaning from Mechanical Ventilation after Traumatic Brain Injury.

We present a 30-year-old male who sustained a mild traumatic brain injury and then was intubated due to deterioration of consciousness. A head CT scan revealed mild brain oedema, a fractured nasal bone and mild left thoracic wall haematoma. Despite complete clinical and radiological normalisation within 36 hours, he failed to wean off the ventilator. The patient was found to have subtle bulbar manifestations including dysphonia, dysarthria, and dysphagia, with recurrent left lung collapse. He responded to an empirical pyridostigmine trial despite negative biochemical tests for myasthenia gravis (MG). The patient was weaned successfully from the ventilator, transferred to a long-term care facility, and then discharged home. Classic symptoms and signs of a disease may be absent, but the presence of dysarthria, dysphagia, transient vocal cord palsy, nasal speech, absent gag reflex and respiratory failure in difficult-to-wean patients, with no definitive diagnosis, may warrant an empirical trial of therapy for suspected MG and for the benefit of any doubt. LEARNING POINTS: "Hidden" cranial injuries may account for subtle bulbar symptoms in victims of traumatic brain injury and should be searched for.Myasthenia gravis has been reported in association with trauma, which comes first and is often difficult to ascertain.A trial of pyridostigmine may be reasonable in difficult-to-wean patients when all other causes have been excluded for the benefit of the doubt.

Seizure Prophylaxis in Young Patients Following Traumatic Brain Injury.

Introduction: Phenytoin is one of the commonly used anti.seizure medications in nontraumatic seizures. However, its utility and safety in young patients with traumatic brain injury (TBI) for the prevention of early-onset seizures (EOS) are debatable. We sought to explore the use of phenytoin as a seizure prophylaxis following TBI. We hypothesized that administering phenytoin is not effective in preventing EOS after TBI. Methods: This was a retrospective observational study conducted on adult TBI patients. EOS was defined as a witnessed seizure within a week postinjury. Data were compared as phenytoin versus no-phenytoin use, EOS versus no-EOS, and among TBI severity groups. Results: During 1 year, 639 TBI patients were included with a mean age of 32 years; of them, 183 received phenytoin as seizure prophylaxis, and 453 received no prophylaxis medication. EOS was documented in 13 (2.0%) patients who received phenytoin, and none had EOS among the nonphenytoin group. The phenytoin group was more likely to have a higher Marshall Score (P = 0.001), lower Glasgow Coma Scale (GCS) (P = 0.001), EOS (P = 0.001), and higher mortality (P = 0.001). Phenytoin was administrated for 15.2%, 43.2%, and 64.5% of mild, moderate, and severe TBI patients, respectively. EOS and no-EOS groups were comparable for age, gender, mechanism of injury, GCS, Marshall Score, serum phenytoin levels, liver function levels, hospital stay, and mortality. Multivariable logistic regression analysis showed that low serum albumin (odds ratio [OR] 0.81; 95% confidence interval [CI] 0.676.0.962) and toxic phenytoin level (OR 43; 95% CI 2.420.780.7) were independent predictors of EOS. Conclusions: In this study, the prophylactic use of phenytoin in TBI was ineffective in preventing EOS. Large-scale matched studies and well-defined hospital protocols are needed for the proper utility of phenytoin post-TBI.

Utility of indocyanine green fluorescent dye in emergency general surgery: a review of the contemporary literature.

For decades, indocyanine green (ICG) has been available for medical and surgical use. The indications for ICG use in surgery have expanded where guided surgery directed by fluorescence and near-infrared fluorescent imaging offers numerous advantages. Recently, surgeons have reported using ICG operative navigation in the emergency setting, with fluorescent cholangiography being the most common procedure. The utility of ICG also involves real-time perfusion assessment, such as ischemic organs and limbs. The rising use of ICG in surgery can be explained by the ICG's rapid technological evolution, accuracy, ease of use, and great potential to guide precision surgical diagnosis and management. The review aims to summarize the current literature on the uses of ICG in emergency general surgery. It provides a comprehensive and practical summary of the use of ICG, including indication, route of administration, and dosages. To simplify the application of ICG, we subdivided its use into anatomical mapping and perfusion assessment. Anatomical mapping includes the biliary tree, ureters, and bowel. Perfusion assessment includes bowel, pancreas, skin and soft tissue, and gonads. This review provides a reference to emergency general surgeons to aid in implementing ICG in the emergency setting for more enhanced and safer patient care.

Can "Stop The Bleed" training courses for laypersons improve hemorrhage control knowledge, skills, and attitudes? A systematic review.

BACKGROUND: In many regions of the world, most trauma deaths occur within 1-2 h of injury due to uncontrolled bleeding. For this reason, training lay first-person responders in trauma care, focusing on hemorrhage control, has been recommended. We hypothesized that STOP THE BLEED (STB) training courses that teach laypersons how to stop traumatic compressible bleeding immediately are needed to potentially prevent deaths due to hemorrhage. This systematic review will analyze the effect of the STB training course on the knowledge, skill, and attitudes of lay first-person responders for hemorrhage control. METHODS: PubMed and Google Scholar databases were used to identify relevant peer-reviewed research articles describing evaluations of STB courses for laypersons from December 1 2013 to October 31 2022. In addition, a hand search of article references was undertaken. Studies were included if they implemented the STB course; trainees were laypersons, and the study had some outcome measures such as knowledge, skill, confidence gained, and willingness to provide or utilization of care provided to and outcomes of trauma patients. RESULTS: The database searches yielded 2,893 unique papers. We retained 33 articles for full-text review, resulting in 24 eligible papers. Gray literature and manual searches yielded 11 additional publications for a total of 35 studies. The most reported finding was a statistically significant increase in hemorrhage control knowledge or tourniquet application skills in 26 studies. Twenty-two studies reported statistically significant improvements in willingness, confidence, comfort, and likelihood to respond to a bleeding patient, and 6 studies reported substantial reductions in the retention of bleeding control knowledge or skills. Only one study reported on the effect on patient outcomes. CONCLUSION: STB courses for laypersons have demonstrated significant improvements in knowledge, skill, confidence, and willingness to intervene to stop traumatic exsanguination. The evaluation of clinically relevant patient outcomes, specifically their effect on preventable deaths from traumatic exsanguination, is needed to strengthen further the evidence behind the recommendations for more widespread teaching of "STB" courses.

Motorcycle-related crashes before and during the COVID-19 pandemic: A comparative retrospective observational study from the Middle East.

BACKGROUND: During the COVID-19 pandemic, there was a boom in the delivery sector, with a significant increase in the demand and number of motorcycle delivery drivers in Qatar, which made them vulnerable to injury. We aimed to evaluate the incidence, pattern, and outcome of patients injured by motorcycle-related crashes (MCC) before and during the pandemic. METHODS: A retrospective observational study included all adult patients admitted with motorcycle-related injuries before the pandemic (March 2018 to February 2020) and during the pandemic (March 2020 to March 2022). Comparative analyses were performed based on (work versus non-work related MCCs) and (pre- versus during the pandemic injuries). RESULTS: 510 patients with MCC were identified, of which 172 (33.7 %) were admitted in the pre-pandemic and 338 (66.3 %) during the pandemic. The mean age of patients was 29.2±7.8 years; 56 % were aged 20-29 years, and 99.4 % were males. Work-related MCCs were more frequent among the younger age group (60.9 % vs. 52.1 %; p=0.001) during the early evening, i.e., 6:00 to 9:00 p.m. (21.9 % vs. 13.9 %; p=0.004). However, non-work related MCC occurred more frequently between midnight and 3:00 am (20.2 % vs. 10.9 %; p=0.004), and such patients were more likely non-compliant for protective devices use (19.3 % vs. 6.1 %; p=0.001) and ride under the influence of alcohol (13.2 % vs. 7.4 %; p=0.03). During the pandemic, the proportion of alcohol consumers (13 % vs. 5.8 %; p=0.01) and work-related MCC (50.9 % vs. 22.7 %; p=0.001) increased significantly compared to the pre-pandemic period. CONCLUSION: The overall burden of MCC increased during the pandemic, and the frequency of MCC involving commercial drivers surged significantly during the pandemic period as opposed to the non-work MCC, which predominated in the pre-pandemic period. Work-related MCCs were more frequent among younger age groups, mainly involving South Asians with frequent accidents in the evening time. However, recreation-related MCCs occurred more frequently at midnight, and victims were non-compliant with the protective gear. Furthermore, there is a need for prospective studies to examine the broader scope of risk factors that are associated with the work-related MCC, especially involving food deliveries, and for focused safety programs for motorcycle delivery drivers and recreational motorcyclists.

Time and Risk Factors of Trauma-Related Mortality: A 5-Year Retrospective Analysis From a National Level I Trauma Center.

Background: We aimed to analyze in-hospital timing and risk factors for mortality in a level 1 trauma center. Methods: This is a retrospective analysis of all trauma-related mortality between 2013 and 2018. Patients were divided and analyzed based on the time of mortality (early (≤48 h) vs late (>48 h)), and within different age groups. Multivariate regression analysis was performed to predict in-hospital mortality. Results: 8624 trauma admissions and 677 trauma-related deaths occurred (47.7% at the scene and 52.3% in-hospital). Among in-hospital mortality, the majority were males, with a mean age of 35.8 ± 17.2 years. Most deaths occurred within 3-7 days (35%), followed by 33% after 1 week, 20% on the first day, and 12% on the second day of admission. Patients with early mortality were more likely to have a lower Glasgow coma scale, a higher shock index, a higher chest and abdominal abbreviated injury score, and frequently required exploratory laparotomy and massive blood transfusion (P < .005). The injury severity scores and proportions of head injuries were higher in the late mortality group than in the early group. The severity of injuries, blood transfusion, in-hospital complications, and length of intensive care unit stay were comparable among the age groups, whereas mortality was higher in the age group of 19 to 44. The higher proportions of early and late in-hospital deaths were evident in the age group of 24 to 29. In multivariate analysis, the shock index (OR 2.26; 95%CI 1.04-4.925; P = .04) was an independent predictor of early death, whereas head injury was a predictor of late death (OR 4.54; 95%CI 1.92-11.11; P = .001). Conclusion: One-third of trauma-related mortalities occur early after injury. The initial shock index appears to be a reliable hemodynamic indicator for predicting early mortality. Therefore, timely hemostatic resuscitation and appropriate interventions for bleeding control may prevent early mortality.

Beta-Adrenergic Receptor Polymorphism and Patho-Genetics of Trauma: A Transformational Frontier of Personalized Medicine in Neurotrauma.

Trauma is a serious public health issue, and remains a major cause of mortality and disability worldwide. The notion that genetic factors contribute to an individual's response to traumatic injury has advanced significantly. Genetic variations in severely injured patients have been linked to mortality, morbidity, and psychological outcomes. We conducted a comprehensive review of beta-adrenergic receptor polymorphisms and their impact on the pathogenetics of traumatic injuries, which could pave the way for a transformational frontier of personalized medicine in neurotrauma. It remains unclear why some individuals are vulnerable to worse outcomes, whereas others are resilient. Although genetic factors may be significant, the intricate interplay between environmental and genetic factors may be responsible for variations in the presentation and outcome after injury. Recent advancements in genetic analysis and molecular physiology have helped to shed light on the causes of such variability. Although exposure to trauma can initiate a cascade of stress-related responses, these responses alone are insufficient to explain etiopathogenesis. Therefore, gaining insights into how trauma and genetic predispositions to adrenergic variations interact at the molecular level to affect an individual's susceptibility and recuperation could provide an essential understanding of the molecular pathogenesis of traumatic injuries. Therefore, it is imperative to identify potential genetic and physiological markers to guide early management and prognosis of trauma. Such knowledge could pave the way for the discovery of novel biomarkers that can identify a transdiagnostic subgroup that is at high risk and requires early intervention. This could lead to the adoption of personalized medical approaches in neurotrauma care.

Independent early predictors of mortality in polytrauma patients: a prospective, observational, longitudinal study

OBJECTIVES: Trauma is an important public health issue and associated with substantial socioeconomic impacts and major adverse clinical outcomes. No single study has previously investigated the predictors of mortality across all stages of care (pre-hospital, emergency room, surgical center and intensive care unit) in a general trauma population. This study was designed to identify early predictors of mortality in severely injured polytrauma patients across all stages of care to provide a better understanding of the physiologic changes and mechanisms by which to improve care in this population. METHODS: A longitudinal, prospective, observational study was conducted between 2010 and 2013 in São Paulo, Brazil. Patients submitted to high-energy trauma were included. Exclusion criteria were as follows: injury severity score <16, <18 years old or insufficient data. Clinical and laboratory data were collected at four time points: pre-hospital, emergency room, and 3 and 24 hours after hospital admission. The primary outcome assessed was mortality within 30 days. Data were analyzed using tests of association as appropriate, nonparametric analysis of variance and generalized estimating equation analysis (p<0.05). ClinicalTrials.gov: NCT01669577. RESULTS: Two hundred patients were included. Independent early predictors of mortality were as follows: arterial hemoglobin oxygen saturation (p<0.001), diastolic blood pressure (p<0.001), lactate level (p<0.001), Glasgow Coma Scale score (p<0.001), infused crystalloid volume (p<0.015) and presence of traumatic brain injury (p<0.001). CONCLUSION: Our results suggest that arterial hemoglobin oxygen saturation, diastolic blood pressure, lactate level, Glasgow Coma Scale, infused crystalloid volume and presence of traumatic brain injury are independent early mortality predictors.

Clotting Factor XIII and desmopressin improve hemostasis in uncontrolled bleeding

PURPOSE: To investigate hemostatic effects of supplementary factor XIII and desmopressin (DDAVP) in resuscitation of uncontrolled bleeding. METHODS: Fifty-four rabbits were randomized in nine groups: G1: Sham; G2: FXIII and normotensive resuscitation (NBP); G3: FXIII and permissive hypotension (PH) (MAP 60% baseline); G4: FXIII/DDAVP/NBP; G5: FXIII/DDAVP/PH; G6: NBP only; G7: FXIII no hemorrhage; G8: FXIII/DDAVP no hemorrhage; G9: PH only. Thromboelastometry and intra-abdominal blood loss were assessed. Scanning electron microscopy (EM) of the clots was performed. RESULTS: Compared to Sham, only G8 (FXIII/DDAVP w/o hemorrhage) showed clotting time (CT) significantly lower (p<0.05). NBP alone (G6) resulted in significantly prolonged CT compared to G2, G3 and G5 (p<0.05). Similarly, median alpha angle was significantly larger in G3,4,5, and 9 compared to G6 (p<0.05). Area under the curve was significantly greater in G5 than G2. Intra-abdominal blood loss was lower in G5 and G9 compared to G2 and G6. FXIII/DDAVP and PH resulted in more robust fibrin mesh by EM. CONCLUSIONS: Normotensive resuscitation provokes more bleeding and worsens coagulation compared to pH, that is partially reversed by factor XIII and desmopressin. FXIII and DDAVP can synergistically improve coagulation. Permissive hypotension reduces bleeding regardless of those agents. .

Jejunum and ileum blunt trauma: what has changed with the implementation of multislice computed tomography? / Trauma contuso de jejuno e íleo: o que mudou com a implementação da tomografia computadorizada multislice?

OBJECTIVE: to evaluate the impact of the new technology of multidetector computed tomography (MDCT) in improving the accuracy and early diagnosis of BSBI. METHODS: patients with blunt small bowel injuries (BSBI) grade> I were identified retrospectively and their CT scans reviewed by an experienced radiologist. Clinical and tomographic findings were analyzed and patients grouped as "pre-MDCT" and "post-MDCT", according to the time of implementation of a 64-slice MDCT. RESULTS: of the 26 patients with BSBI 16 had CT scans. Motor vehicle collision (62.5%) was the most frequent mechanism of injury. In the pre-MDCT period, five of the 13 patients (38.5%) had abdominal CT, and in the post-MDCT, 11 of 13 patients (84.6%) had the exam. During pre-MDCT, all CT scans were abnormal with findings of pneumoperitoneum (60%), free fluid (40%) and bowel wall enhancement (20%). In the post-MDCT group, all exams but one were abnormal and the most frequent findings were free fluid (90.9%), bowel wall enhancement (72.7%), and pneumoperitoneum (54.5%). However, the rate of delayed laparotomy did not change. The mortality rate in both groups were similar, with 20% during pre-MDCT and 18.2% during post-MDCT. CONCLUSION: the use of MDCT in abdominal trauma in our service has increased the sensibility of the diagnosis, but has had no impact on outcome so far. .

OBJETIVO: avaliar se o avanço tecnológico dos aparelhos de tomografia computadorizada (TC) melhorou a acurácia e rapidez no diagnóstico dessas lesões. MÉTODOS: pacientes com lesão de intestino delgado grau>I (AAST-OIS) por trauma contuso foram identificados e suas imagens de TC analisadas por especialista. Foram analisados achados clínicos e tomográficos agrupando os pacientes em antes e após o uso da TC multislice 64 canais, incorporada em nosso Serviço em abril de 2009. RESULTADOS: Dentre os 26 pacientes identificados entre 2005 e 2012, 16 realizaram TC. Acidente automobilístico (62,5%) foi o principal mecanismo de trauma. No período pré-multislice, cinco dentre 13 pacientes (38,5%) realizaram TC e no pós-multislice 11 de 13 (84,6%). No grupo pré-multislice todos os exames foram alterados, sendo os principais achados pneumoperitônio (60%), liquido livre (40%) e espessamento da parede intestinal (20%). No grupo pós-multislice apenas um exame foi considerado normal e os achados mais frequentes nos outros 10 casos foram: líquido livre (90,9%), espessamento da gordura do mesentério (72,7%) e pneumoperitônio (54,5%). Não foi observada mudança no intervalo de tempo entre a realização de TC e a laparotomia. A mortalidade em ambos os grupos foi semelhante (20% no pré-multislice e 18,2% no pós-multislice). CONCLUSÃO: O uso de tomografia multislice aumentou a sensibilidade do diagnóstico, porém sem alteração na evolução dos pacientes. .

Is there a role for pyloric exclusion after severe duodenal trauma? / Existe lugar para a exclusão pilórica no trauma duodenal grave?

Duodenal trauma is an infrequent injury, but linked to high morbidity and mortality. Surgical management of duodenal injuries is dictated by: patient's hemodynamic status, injury severity, time of diagnosis, and presence of concomitant injuries. Even though most cases can be treated with primary repair, some experts advocate adjuvant procedures. Pyloric exclusion (PE) has emerged as an ancillary method to protect suture repair in more complex injuries. However, the effectiveness of this procedure is debatable. The "Evidence Based Telemedicine - Trauma & Acute Care Surgery" (EBT-TACS) Journal Club performed a critical appraisal of the literature and selected three relevant publications on the indications for PE in duodenal trauma. The first study retrospectively compared 14 cases of duodenal injuries greater than grade II treated by PE, with 15 cases repaired primarily, all of which penetrating. Results showed that PE did not improve outcome. The second study, also retrospective, compared primary repair (34 cases) with PE (16 cases) in blunt and penetrating grade > II duodenal injuries. The authors concluded that PE was not necessary in all cases. The third was a literature review on the management of challenging duodenal traumas. The author of that study concluded that PE is indicated for anastomotic leak management after gastrojejunostomies. In conclusion, the choice of the surgical procedure to treat duodenal injuries should be individualized. Moreover, there is insufficient high quality scientific evidence to support the abandonment of PE in severe duodenal injuries with extensive tissue loss.

O trauma duodenal é incomum, mas possui alta morbimortalidade. As condições clínicas dos pacientes, gravidade das lesões, tempo de diagnóstico e lesões associadas influenciam na escolha do procedimento operatório. A maioria das lesões duodenais é tratada com reparo primário. Procedimentos adjuvantes para proteger a linha de sutura e evitar deiscência podem ser úteis em lesões complexas. Embora a exclusão pilórica (EP) seja utilizada em lesões duodenais graves, há controvérsia quanto a sua necessidade. A reunião "Telemedicina Baseada em Evidências - Cirurgia do Trauma e Emergência" (TBE-CiTE) revisou a literatura e selecionou três publicações relevantes sobre as indicações de EP no trauma duodenal. O primeiro estudo, retrospectivo, comparou 14 pacientes com ferimentos penetrantes duodenais grau > II, tratados com EP, com 15 pacientes semelhantes tratados com reparo primário; não houve diferença nos resultados. O segundo, também retrospectivo, comparou o reparo primário (34 casos) com EP (16 casos), em lesões duodenais contusas ou penetrantes grau > II. Os autores concluíram que a EP não é necessária para todos os pacientes, apesar de lesões duodenais graves. O terceiro estudo constituiu-se de revisão da literatura sobre os desafios do tratamento dos traumatismos duodenais. Na experiência do autor, a EP é útil nos casos de fístula de anastomoses gastrojejunais. Conclui-se que a escolha do procedimento operatório no tratamento das lesões duodenais deve ser individualizada. Não há evidência cientifica de boa qualidade para justificar o abandono da EP no tratamento das lesões duodenais graves com grande perda tecidual.

Management of stab wounds to the anterior abdominal wall / Abordagem dos ferimentos por arma branca na parede anterior do abdome

The meeting of the Publication "Evidence Based Telemedicine - Trauma and Emergency Surgery" (TBE-CiTE), through literature review, selected three recent articles on the treatment of victims stab wounds to the abdominal wall. The first study looked at the role of computed tomography (CT) in the treatment of patients with stab wounds to the abdominal wall. The second examined the use of laparoscopy over serial physical examinations to evaluate patients in need of laparotomy. The third did a review of surgical exploration of the abdominal wound, use of diagnostic peritoneal lavage and CT for the early identification of significant lesions and the best time for intervention. There was consensus to laparotomy in the presence of hemodynamic instability or signs of peritonitis, or evisceration. The wound should be explored under local anesthesia and if there is no injury to the aponeurosis the patient can be discharged. In the presence of penetration into the abdominal cavity, serial abdominal examinations are safe without CT. Laparoscopy is well indicated when there is doubt about any intracavitary lesion, in centers experienced in this method.

A reunião de Revista "Telemedicina Baseada em Evidências - Cirurgia do Trauma e Emergência" (TBE-CiTE) através de revisão da literatura selecionou três artigos recentes sobre o tratamento do paciente vítima de agressão por arma branca na parede abdominal. O primeiro trabalho observou o papel da tomografia computadorizada (TC) no tratamento do paciente com agressão por arma branca na parede abdominal. O segundo analisou o uso da laparoscopia diagnóstica em detrimento do exame físico seriado para avaliar os pacientes com necessidade de laparotomia terapêutica. O terceiro fez uma avaliação da exploração cirúrgica do ferimento abdominal, uso do lavado peritoneal diagnóstico e TC na identificação precoce de lesões significativas e o melhor momento para intervenção. Houve consenso para a indicação de laparotomia na presença de instabilidade hemodinâmica, ou sinais de peritonite, ou evisceração. O ferimento deve ser explorado sob anestesia local e se não houver lesão da aponeurose o doente pode receber alta. Na presença de penetração na cavidade abdominal, o exame seriado do abdome é seguro, sem a necessidade de TC. A laparoscopia está bem indicada quando existe dúvida de lesão intracavitária em centros com experiência nesse método.

Indicações de tomografia de crânio em crianças com trauma cranioencefálico leve / Indications for head computed tomography in children with mild traumatic brain injury

A reunião de revista "Telemedicina Baseada em Evidência - Cirurgia do Trauma e Emergência" (TBE-CiTE) realizou uma revisão crítica da literatura e selecionou os três artigos mais relevantes e atuais sobre a indicação de tomografia de crânio em pacientes pediátricos com trauma craniencefálico leve (TCE). O primeiro trabalho identificou pacientes vítimas de TCE leve com fatores de alto e baixo risco de apresentarem lesões intracranianas vistas à tomografia computadorizada (TC) de crânio e com necessidade de intervenção neurocirúrgica. O segundo trabalho avaliou o uso das recomendações do "National Institute of Clinical Excellence" em pacientes pediátricos com TCE, e utilizou como variáveis de desfecho a realização de TC ou internação hospitalar. O último artigo analisou e identificou os pacientes onde a TC de crânio seria desnecessária e, portanto, não deve ser feita rotineiramente. Baseado nessa revisão crítica da literatura e a discussão com especialistas, o TBE-CiTE concluiu que é importante evitar a exposição desnecessária de crianças com TCE leve à radiação ionizante da TC de crânio. O grupo favoreceu a utilização do guideline do PECARN onde ECG de 14, alteração do nível de consciência ou fratura do crânio palpável são indicações de TC de crânio, ou quando a experiência do médico, achados múltiplos ou piora dos sintomas ocorrerem.

The "Evidence Based Telemedicine - Trauma and Emergency Surgery" (TBE-CITE) performed a critical appraisal of the literature and selected the three most relevant and recent publications on the indications for head computed tomography (CT) scan in pediatric patients with mild traumatic brain injury (TBI). The first study identified patients with mild TBI, high and low risk factors for intracranial injuries detected on CT scan and need for neurosurgical intervention. The second study evaluated the guidelines of the National Institute of Clinical Excellence for pediatric patients with TBI. The outcome of this study was either performing a head CT scan or hospital admission. The last study identified and analyzed the patients in whom the CT scan is not necessary and consequently should not be routinely indicated. Based on the critical appraisal of the literature and expert discussion, the opinion of the TBE-CITE was to favor the adoption of the PECARN guidelines, proposing CT scans for children with GCS of 14, altered level of consciousness and palpable skull fracture, or when the physician experience, multiple findings or worsening symptoms warrant it.

Uso de corticoide na profilaxia para síndrome de embolia gordurosa em pacientes com fratura de osso longo / The use of corticosteroid for the prophylaxis of fat embolism syndrome in patients with long bone fracture

A reunião de revista "Telemedicina Baseada em Evidência - Cirurgia do Trauma e Emergência" (TBE-CiTE) realizou uma revisão crítica da literatura e selecionou três artigos recentes sobre o uso de corticoide para a profilaxia da síndrome de embolia gordurosa. O foco desta revisão foi a indicação ou não do uso de corticoide nos pacientes admitidos na unidade de terapia intensiva (UTI) com risco de desenvolverem embolia gordurosa pós traumática. O primeiro artigo foi um estudo prospectivo com o objetivo de estabelecer fatores preditivos confiáveis, precoces e úteis associados ao aparecimento da síndrome da embolia gordurosa (SEG) em pacientes traumatizados. O segundo artigo foi uma revisão de literatura sobre o papel do corticoide como medida profilática à síndrome de embolia gordurosa. O último artigo foi uma meta-análise sobre a capacidade do corticoide em reduzir o risco de síndrome da embolia gordurosa nos pacientes com fraturas de ossos longos. As principais conclusões e recomendações foram que pacientes traumatizados devem ser monitorizados na UTI com oximetria de pulso e medida do lactato já que estes fatores podem predizer o aparecimento de SEG e que não existe evidência suficiente para recomendar o uso de corticoide para a profilaxia desta síndrome.

The "Evidence-based Telemedicine - Trauma & Acute Care Surgery" (EBT-TACS) Journal Club conducted a critical review of the literature and selected three recent studies on the use of corticosteroids for the prophylaxis of fat embolism syndrome. The review focused on the potential role of corticosteroids administration to patients admitted to the intensive care unit (ICU) at risk of developing post-traumatic fat embolism. The first study was prospective and aimed at identifying reliable predictors, which occurred early and were associated with the onset of fat embolism syndrome in trauma patients. The second manuscript was a literature review of the role of corticosteroids as a prophylactic measure for fat embolism syndrome (FES). The last manuscript was a meta-analysis on the potential for corticosteroids to prophylactically reduce the risk of fat embolism syndrome in patients with long bone fractures. The main conclusions and recommendations reached were that traumatized patients should be monitored with non-invasive pulse oximetry and lactate levels since these factors may predict the development of FES, and that there is not enough evidence to recommend the use of steroids for the prophylaxis of this syndrome.
