Surgical Management of Wilms Tumors with Intravenous Extension: A Multicenter Analysis of Clinical Management with Technical Insights.

BACKGROUND: About 5% of Wilms tumors present with vascular extension, which sometimes extends to the right atrium. Vascular extension does not affect the prognosis, but impacts the surgical strategy, which is complex and not fully standardized. Our goal is to identify elements of successful surgical management of Wilms tumors with vascular extensions. PATIENTS AND METHODS: A retrospective study of pediatric Wilms tumors treated at three sites (January 1999-June 2019) was conducted. The inclusion criterion was the presence of a renal vein and vena cava thrombus at diagnosis. Tumor stage, pre and postoperative treatment, preoperative imaging, operative report, pathology, operative complications, and follow-up data were reviewed. RESULTS: Of the 696 pediatric patients with Wilms tumors, 69 (9.9%) met the inclusion criterion. In total, 24 patients (37.5%) had a right atrial extension and two presented with Budd-Chiari syndrome at diagnosis. Two died at diagnosis owing to pulmonary embolism. All patients received neoadjuvant chemotherapy and thrombus regressed in 35.6% of cases. Overall, 14 patients had persistent intra-atrial thrombus extension (58%) and underwent cardiopulmonary bypass. Most thrombi (72%) were removed intact with nephrectomy. Massive intraoperative bleeding occurred during three procedures. Postoperative renal insufficiency was identified as a risk factor for patient survival (p = 0.01). With a median follow-up of 9 years (range: 0.5-20 years), overall survival was 89% and event-free survival was 78%. CONCLUSIONS: Neoadjuvant chemotherapy with proper surgical strategy resulted in a survival rate comparable to that of children with Wilms tumors without intravascular extension. Clinicians should be aware that postoperative renal insufficiency is associated with worse survival outcomes.

Barriers and challenges to achieving equity in global children's surgery: A call to action.

CHALLENGES: A Call to Action.

Trauma and sexual abuse in children-Epidemiology, challenges, management strategies and prevention in lower- and middle-income countries.

Trauma is rising as a cause of morbidity and mortality in lower- and middle-income countries (LMIC). This article describes the Epidemiology, Challenges, Management strategies and prevention of pediatric trauma in lower- and middle-income countries. The top five etiologies for non-intentional injuries leading to death are falls, road traffic injuries, burns, drowning and poisoning. The mortality rate in LMICs is twice that of High-Income Countries (HICs) irrespective of injury severity adjustment. The reasons for inadequate care include lack of facilities, transportation problems, lack of prehospital care, lack of resources and trained manpower to handle pediatric trauma. To overcome these challenges, attention to protocolized care and treatment adaptation based on resource availability is critical. Training in management of trauma helps to reduce the mortality and morbidity in pediatric polytrauma cases. There is also a need for more collaborative research to develop preventative measures to childhood trauma.

Surgery in Bilateral Wilms Tumor-A Single-Center Experience.

The treatment of bilateral Wilms tumors (BWT) involves curing the cancer, preserving long-term renal function, and maintaining a good quality of life. Established methods for achieving these goals include preoperative chemotherapy and nephron-sparing surgery (NSS). This study aimed to evaluate the experience of a single institution in treating patients with BWT. We analyzed cases of BWT treated at the Pediatric Oncology Institute-GRAACC-Federal University of São Paulo over a period of 35 years. Bleeding control was performed with manual compression of the renal parenchyma. Thirty-three patients were included in the study. Thirty cases were synchronous tumors. The mean age at diagnosis was 30.4 months (±22 m) and 66.7% were girls. The median follow-up period was 83 months. Neoadjuvant chemotherapy was the primary approach in most patients (87.9%), with a simultaneous upfront surgical approach performed in 84.8%. Most patients underwent bilateral NSS (70.4%). There were no early complications in this series, but 39.4% had clinical complications. The five-year survival rate was 76%. Therefore, it is clear that the surgical approach to BWT plays a crucial role in achieving good outcomes. However, it is difficult to standardize surgical techniques and technology may have the potential to enhance safety.

Development of a template for operative reporting of pediatric cancer surgery in limited-resource settings by using a modified Delphi method.

PURPOSE: A comprehensive operative report for cancer surgery is crucial for accurate disease staging, risk stratification, and therapy escalation/de-escalation, which affects the outcome. Narrative operative reports may fail to include some critical findings. Furthermore, standardized operative reports can form the basis of a local registry, which is often lacking in limited-resource settings (LRSs). In adult literature, synoptic operative reports (SOR) contain more key findings than narrative operative reports. In the LRSs, where the capacity of diagnostic pathology services is typically suboptimal, the value of a thorough operative report is even greater. The aim of this study was to develop a SOR template to help standardize childhood cancer surgery reporting in LRSs. METHODS: Twenty-three experts in pediatric cancer with extensive experience practicing in LRSs were invited to participate in a modified Delphi procedure. SOR domains for pediatric oncology surgery were drafted based on a literature search and then modified based on experts' opinions. The experts anonymously answered multiple rounds of online questionnaires until all domains and subdomains reached a consensus, which was predefined as 70% agreement. RESULTS: Sixteen experts participated in the study, and two rounds of the survey were completed. Twenty-one domains were considered relevant, including demographics, diagnosis, primary site, preoperative disease stage, previous tumor biopsy or surgery, preoperative tumor rupture, neoadjuvant therapy, surgical access, type of resection, completeness of resection, tumor margin assessment, locoregional tumor extension, organ resection, intraoperative tumor spillage, vascular involvement, lymph node sampling, estimated blood loss, intraoperative complications and interventions to address them, specimen names, and specimen orientation. CONCLUSION: We developed a SOR template for pediatric oncology surgery in LRSs. Consensus for all 21 domains and associated subdomains was achieved using a modified Delphi procedure.

Limitations of using the DATASUS database as a primary source of data in surgical research: a scoping review.

OBJECTIVE: DATASUS is the Brazilian Public Unified Health System (SUS) department responsible for providing health data that are used as a primary source of data in several studies on surgery and surgical specialties although its main limitations have not been previously reviewed. The objective of this work is to synthesize information from studies on surgery that used DATASUS systems as a data source and to identify the main gaps in this platform. METHODS: a scoping review was conducted according to the PRISMA-ScR method to identify papers on surgery, and other surgical specialties, that used the DATASUS platform as a primary data source. No restrictions were imposed regarding the type of study or year of publication. Grounded Theory was used to analyze the content of the articles. RESULTS: 248 works were initially analyzed and 47 were included in the final analysis of this study. The original articles included were published between 2009 and 2022 and the majority (12.76%, n=6) were published in the Journal of the Brazilian College of Surgeons. Retrospective studies (40.43%, n=19) were the most common type of study found. Content analysis of the articles identified four predominant domains in the scientific literature about the limitations of using DATASUS in surgical research: lack of data, reliability, precision and data integration. CONCLUSION: the information systems available in DATASUS are the largest source of information about the SUS, but the scientific literature on the quality of data available in these systems remains scarce and studies aimed at measuring this metric are necessary.

Surgically Amenable Childhood Cancers: An Overview of the Burden and Challenges of Management in Low- and Middle-Income Countries.

The World Health Organization's Global Initiative for Childhood Cancer was launched to decrease the disparities in childhood cancer outcomes and improve treatments for childhood cancer in resource-limited settings. Low-grade glioma, retinoblastoma, and Wilms tumors are among the index cancers included in this global initiative, as these cancers represent a large percentage of childhood tumors and are curable with cost-effective, evidence-based interventions. Herein, we discuss the global childhood tumor burden, the status of pediatric cancer surgery capacity and services around the world, and the strategic considerations for building pediatric surgical oncology capacity.

Direct transport versus inter-hospital transfer of trauma victims in the Brazilian Emergency Medical System.

Introduction: The Brazilian medical emergency services presented a significant development due to the investment in emergency care units, increasing the expansion of the services. However, there was a surge in need for secondary patient transfers, which served as the common link in a wide web of tertiary hospital access. This study aimed to assess the outcome of trauma patients who required secondary transfer. Patients and methods: This prospective observational cross-sectional study included 2302 patients (565 from the study group and 1737 from the control group) and compared the outcome of patients hospitalized for trauma referred by secondary transfer or those who directly visited the Emergency Unit of the municipality with a Brazilian medical emergency system. Results: As for the trauma mechanism, there was a predominance of blunt trauma (93.32 %), 34.5 % were elderly, 12.45 % suffered severe traumatic brain injury, and 18.44 % had severe trauma rate (injury severity score > 15). The outcome of death did not present a significant difference between the groups, even when evaluated considering possible risk factors, such as the elderly age (over 65 years of age) and trauma index. Conclusion: There was no significant difference in terms of the outcome of death in patients who underwent secondary transfer and those with direct access to medical emergency services. However, patients who underwent secondary transfer had an increase in the length of hospital stay.

The importance of pediatric trauma prevention: The work of Criança Segura - Safe Kids Brazil.

Trauma is the leading cause of death in children and adolescents less than 14 years of age worldwide. Although there have been advances regarding treatment in the last decades, it is still complex to assemble well-trained teams and proper hospitals to care for traumatized children. The most effective vaccine and the less expensive tool to deal with such a burden is prevention. The aim of the Non-Governmental Organization (NGO) Criança Segura - Safe Kids Brazil is to work with child and adolescent trauma prevention through three pillars: mobilization, communication, and public policy. Nationwide actions, campaigns, education material, events, research, and proposing laws resulted in a 53% decrease of trauma deaths in Brazil in a 20-year period. The strategy contributes to build the culture of prevention in Brazil with the involvement of every sector of society. Childhood trauma prevention is effective in decreasing trauma deaths. Criança Segura is now part of Children's Villages, an international organization that will be able to multiply the model through different countries. LEVELS OF EVIDENCE: Review article.

Limitations of using the DATASUS database as a primary source of data in surgical research: a scoping review / Limitações do uso da base de dados DATASUS como fonte primária de dados em pesquisas em cirurgia: uma revisão de escopo

RESUMO Objetivo: o DATASUS é o departamento do SUS responsável por disponibilizar dados de saúde que são empregados como fonte primária de dados em diversos estudos sobre cirurgia e especialidades cirúrgicas, embora principais limitações não tenham sido revisadas anteriormente. O objetivo deste trabalho é sintetizar as informações de estudos sobre cirurgia que utilizaram sistemas do DATASUS como fonte de dados, identificando as principais lacunas. Métodos: uma revisão de escopo foi conduzida de acordo com o método PRISMA-ScR para a identificação de trabalhos sobre cirurgia, e outras especialidade cirúrgicas, que utilizaram a plataforma DATASUS como fonte primária de dados. Nenhuma restrição foi imposta em relação ao tipo de estudo ou ano de publicação. A Teoria Fundamentada em Dados foi utilizada para a análise do conteúdo dos artigos. Resultados: 248 trabalhos foram inicialmente analisados e 47 foram incluídos na análise final deste estudo. Os artigos originais incluídos foram publicados entre 2009 e 2022, maioria (12,76%, n=6) foi publicada na Revista do Colégio Brasileiro de Cirurgiões. Estudos retrospectivos (40,43%, n=19) foram o tipo de estudo mais comum encontrado. A análise dos artigos identificou quatro domínios predominantes na literatura científica acerca das limitações do uso de DATASUS em pesquisas em cirurgia: falta de dados, confiabilidade, precisão e integralização dos dados. Conclusão: os sistemas de informação dispostos no DATASUS constituem a maior fonte de informações sobre o SUS, porém a literatura científica sobre a qualidade dos dados dispostos nestes sistemas permanece escassa e trabalhos direcionados a mensurar essa métrica são necessários.

A debriefing tool to acquire non-technical skills in trauma courses.

Objective: The study reports the use of a nominal group technique (NGT) to evaluate the PEARLS Healthcare debriefing tool as a tool to foster non-technical skills in trauma simulation courses. Additionally, it introduces a debriefing card to be used in trauma courses. Design: A nominal group technique was used to evaluate the main strategies for PEARLS. The experts had the opportunity to share their opinions in an online survey and online meeting. Results: Seven participants participated in the nominal group. Based on the online survey results, the self-assessment debriefing strategy (from PEARLS) was rated 4.83/5 in relevance, the focused facilitation 5/5, and the provision of information 4.5/5. Participants felt that PEARLS was appropriate and useful for fostering non-technical skills: all the debriefing strategies contained in PEARLS were felt to be valid and worth using; and cue cards for the instructors were suggested to assist them in conducting structured formal debriefings. A specific debriefing tool for trauma scenarios was designed based on these suggestions, which is presented in this article. Conclusion: A nominal group of experts in education, simulation, and trauma support PEARLS strategies for non-technical skills training in trauma courses.

Prognostic factors in treatment of traumatic femoropopliteal arterial injuries at a Brazilian trauma center.

Background: Despite significant improvements in outcomes, traumatic arterial limb injuries remain a significant cause of limb loss and mortality. Objectives: This study sought to identify predictors of mortality and major amputation in patients undergoing revascularization after femoropopliteal arterial trauma. Methods: This was a retrospective review of a trauma registry from an urban trauma center in Brazil. All patients admitted to our hospital with a femoropopliteal arterial injury from November 2012 to December 2017 who underwent vascular reconstruction were included. Univariate analyses and logistic regression analyses were conducted to identify factors independently associated with the primary outcome of amputation and the secondary outcome of mortality. Results: Ninety-six patients were included. Eleven patients (11.5%) had an amputation and 14 (14.6%) died. In the logistic regression model for amputation, patients with ischemia duration greater than 6 hours were approximately 10 times more likely to undergo an amputation compared to those with ischemia duration less than or equal to 6 hours (adjusted odds ratio (AOR) [95% confidence interval (CI)]: 9.6 [1.2-79.9]). The logistic regression model for mortality revealed that patients with ischemia duration greater than 6 hours were approximately 6 times more likely to die compared to those with ischemia duration less than or equal to 6 hours (AOR [95% CI]: 5.6 [1.3 to 24.7). Conclusions: Ischemia duration remains the most important factor independently associated with limb loss and mortality for patients undergoing femoropopliteal arterial revascularization after traumatic injuries. Physiological status on admission and trauma scores are also important.

Contexto: As lesões arteriais traumáticas de membros ainda permanecem uma causa significativa de perda de membros e mortalidade, apesar de melhorias significativas observadas nos resultados após a ocorrências dessas lesões. Objetivos: Este estudo buscou identificar preditores de mortalidade e amputações em pacientes submetidos à revascularização após trauma arterial femoropoplíteo. Métodos: Esta é uma revisão de um Registro de Trauma Vascular. Todos os pacientes com lesão arterial femoropoplítea internados em nosso hospital de novembro de 2012 a dezembro de 2017 e submetidos a reconstrução vascular foram incluídos. Análises univariadas, seguidas de análises de regressão logística, foram realizadas para identificar fatores independentemente associados com os resultados primários de amputação e mortalidade. Resultados: Foram incluídos 96 pacientes, com média de 27 anos. O Revised Trauma Score (RTS) foi, em média, 7,152; já o Injury Severity Score (ISS) foi, em média, 15. Onze pacientes (11,5%) tiveram amputação, e 14 pacientes (14,6%) morreram. Observou-se que pacientes com o tempo de isquemia maior que 6 horas apresentaram aproximadamente 10 vezes mais chance de amputação do que aqueles com tempo igual ou menor que 6 horas (intervalo de confiança de 95% [IC95%]: 1,2 a 79,9). O tempo de isquemia maior que 6 horas aumentou em aproximadamente 6 vezes a chance de mortalidade (IC95%: 1,26 a 24,77). A instabilidade hemodinâmica aumentou em 9 vezes a chance de mortalidade (IC95%: 2,36 a 36,67). Conclusões: O tempo de isquemia continua sendo o fator mais importante independentemente associado a amputação e óbito em pacientes submetidos à revascularização arterial femoropoplítea após traumas. O estado fisiológico e os escores de trauma são importantes.

Evidence-based surgical guidelines for treating children with Wilms tumor in low-resource settings.

BACKGROUND: Survival of Wilms tumor (WT) is > 90% in high-resource settings but < 30% in low-resource settings. Adapting a standardized surgical approach to WT is challenging in low-resource settings, but a local control strategy is crucial to improving outcomes. OBJECTIVE: Provide resource-sensitive recommendations for the surgical management of WT. METHODS: We performed a systematic review of PubMed and EMBASE through July 7, 2020, and used the GRADE approach to assess evidence and recommendations. RECOMMENDATIONS: Initiation of treatment should be expedited, and surgery should be done in a high-volume setting. Cross-sectional imaging should be done to optimize preoperative planning. For patients with typical clinical features of WT, biopsy should not be done before chemotherapy, and neoadjuvant chemotherapy should precede surgical resection. Also, resection should include a large transperitoneal laparotomy, adequate lymph node sampling, and documentation of staging findings. For WT with tumor thrombus in the inferior vena cava, neoadjuvant chemotherapy should be given before en bloc resection of the tumor and thrombus and evaluation for viable tumor thrombus. For those with bilateral WT, neoadjuvant chemotherapy should be given for 6-12 weeks. Neither routine use of complex hilar control techniques during nephron-sparing surgery nor nephron-sparing resection for unilateral WT with a normal contralateral kidney is recommended. When indicated, postoperative radiotherapy should be administered within 14 days of surgery. Post-chemotherapy pulmonary oligometastasis should be resected when feasible, if local protocols allow omission of whole-lung irradiation in patients with nonanaplastic histology stage IV WT with pulmonary metastasis without evidence of extrapulmonary metastasis. CONCLUSION: We provide evidence-based recommendations for the surgical management of WT, considering the benefits/risks associated with limited-resource settings.

Thyroid cancer in children: A multicenter international study highlighting clinical features and surgical outcomes of primary and secondary tumors.

Background: Thyroid gland malignancies are rare in pediatric patients (0.7% of tumors); only 1.8% are observed in patients aged <20 years, with a higher prevalence recorded in women and adolescents. Risk factors include genetic syndromes, MEN disorders, autoimmune diseases, and exposure to ionizing radiation. Radiotherapy is also associated with an increased risk of secondary thyroid cancer. This study describes the clinical features and surgical outcomes of primary and secondary thyroid tumors in pediatric patients. Methods: Institutional data were collected from eight international surgical oncology centers for pediatric patients with thyroid cancer between 2000 and 2020. Statistical analyses were performed using the GraphPad Prism software. Results: Among 255 total cases of thyroid cancer, only 13 (5.1%) were secondary tumors. Primary thyroid malignancies were more likely to be multifocal in origin (odds ratio [OR] 1.993, 95% confidence interval [CI].7466-5.132, p = 0.2323), have bilateral glandular location (OR 2.847, 95% CI.6835-12.68, p = 0.2648), and be metastatic at first diagnosis (OR 1.259, 95% CI.3267-5.696, p > 0.999). Secondary tumors showed a higher incidence of disease relapse (OR 1.556, 95% CI.4579-5.57, p = 0.4525) and surgical complications (OR 2.042, 95% CI 0.7917-5.221, p = 0.1614), including hypoparathyroidism and recurrent laryngeal nerve injury. The overall survival (OS) was 99% at 1 year and 97% after 10 years. No EFS differences were evident between the primary and secondary tumors (chi-square 0.7307, p = 0.39026). Conclusions: This multicenter study demonstrated excellent survival in pediatric thyroid malignancies. Secondary tumors exhibited greater disease relapse (15.8 vs. 10.5%) and a higher incidence of surgical complications (36.8 vs. 22.2%).

Estimates of Treatable Deaths Within the First 20 Years of Life from Scaling Up Surgical Care at First-Level Hospitals in Low- and Middle-Income Countries.

BACKGROUND: Surgical care is an important, yet often neglected component of child health in low- and middle-income countries (LMICs). This study examines the potential impact of scaling up surgical care at first-level hospitals in LMICs within the first 20 years of life. METHODS: Epidemiological data from the global burden of disease 2019 Study and a counterfactual method developed for the disease control priorities; 3rd Edition were used to estimate the number of treatable deaths in the under 20 year age group if surgical care could be scaled up at first-level hospitals. Our model included three digestive diseases, four maternal and neonatal conditions, and seven common traumatic injuries. RESULTS: An estimated 314,609 (95% UI, 239,619-402,005) deaths per year in the under 20 year age group could be averted if surgical care were scaled up at first-level hospitals in LMICs. Most of the treatable deaths are in the under-5 year age group (80.9%) and relates to improved obstetrical care and its effect on reducing neonatal encephalopathy due to birth asphyxia and trauma. Injuries are the leading cause of treatable deaths after age 5 years. Sixty-one percent of the treatable deaths occur in lower middle-income countries. Overall, scaling up surgical care at first-level hospitals could avert 5·1% of the total deaths in children and adolescents under 20 years of age in LMICs per year. CONCLUSIONS: Improving the capacity of surgical services at first-level hospitals in LMICs has the potential to avert many deaths within the first 20 years of life.

International Society of Paediatric Surgical Oncology (IPSO) Surgical Practice Guidelines.

Most children with tumors will require one or more surgical interventions as part of the care and treatment, including making a diagnosis, obtaining adequate venous access, performing a surgical resection for solid tumors (with staging and reconstruction), performing procedures for cancer prevention and its late effects, and managing complications of treatment; all with the goal of improving survival and quality of life. It is important for surgeons to adhere to sound pediatric surgical oncology principles, as they are closely associated with improved local control and survival. Unfortunately, there is a significant disparity in survival rates in low and middle income countries, when compared to those from high income countries. The International Society of Paediatric Surgical Oncology (IPSO) is the leading organization that deals with pediatric surgical oncology worldwide. This organization allows experts in the field from around the globe to gather and address the surgical needs of children with cancer. IPSO has been invited to contribute surgical guidance as part of the World Health Organization Initiative for Childhood Cancer. One of our goals is to provide surgical guidance for different scenarios, including those experienced in High- (HICs) and Low- and Middle-Income Countries (LMICs). With this in mind, the following guidelines have been developed by authors from both HICs and LMICs. These have been further validated by experts with the aim of providing evidence-based information for surgeons who care for children with cancer. We hope that this initiative will benefit children worldwide in the best way possible. Simone Abib, IPSO President Justin T Gerstle, IPSO Education Committee Chair Chan Hon Chui, IPSO Secretary.

Lessons Learned From Treating 114 Inferior Vena Cava Injuries at a Limited Resources Environment - A Single Center Experience.

BACKGROUND: The inferior vena cava is the most frequently injured vascular structure in penetrating abdominal trauma. We aimed to review inferior vena cava injury cases treated at a limited resources facility and to discuss the surgical management for such injures. METHODS: This was a retrospective study of patients with inferior vena cava injuries who were treated at a single center between January 2011 and January 2020. Data pertaining to the following were assessed: demographic parameters, hypovolemic shock at admission, the distance that the patient had to be transported to reach the hospital, affected anatomical segment, treatment, concomitant injuries, complications, and mortality. Non-parametric data were analyzed using Fisher's exact, Chi-square, Mann-Whitney, or Kruskal-Wallis test, as applicable. The Student's t-test was used to assess parametric data. Moreover, multiple logistic regression analyses (including data of possible death-related variables) were performed. Statistical significance was set at P <0.05. RESULTS: Among 114 patients with inferior vena cava injuries, 90.4% were male, and the majority were aged 20-29 years. Penetrating injuries accounted for 98.2% of the injuries, and the infrarenal segment was affected in 52.7% of the patients. Suturing was perfomed in 69.5% and cava ligation in 29.5% of the patients, and 1 patient with retrohepatic vena cava injury was managed non-operatively. The overall mortality was 52.6% with no case of compartment syndrome in the limbs. A total of 7.9% of the patients died during surgery. CONCLUSION: The inferior vena cava is often injured by penetrating mechanisms, and the most frequently affected segment was the infrarenal segment. A higher probability of death was not associated with injury to a specific anatomical segment. Additionally, cava ligation was not related to an increased probability of compartment syndrome in the leg; therefore, prophylactic fasciotomy was not supported.

Perfil de pacientes pediátricos de um centro de trauma no Brasil: um estudo transversa / Profile of pediatric patients from a trauma center in Brazil: a cross-sectional study

Objetivos: Descrever a epidemiologia dos pacientes pediátricos internados em um centro de trauma em Minas Gerais, Brasil; caracterizar os dados desde admissão hospitalar até a propedêutica. Métodos: Trata-se de estudo retrospectivo cuja coleta de dados aconteceu entre outubro de 2017 e março de 2018 no Hospital João XXIII. Foram incluídas crianças menores de 14 anos que foram classificadas como vítimas de trauma de "muito urgência" ou "emergência" pelo protocolo de Manchester. Foi realizada análise descritiva, que incluiu as seguintes variáveis: idade, sexo, mecanismo de trauma, especialidade médica do provedor de primeira avaliação, necessidade de procedimentos cirúrgicos, propedêutica e óbito. Resultados: A média de idade dos pacientes foi 6,9 anos. O principal mecanismo de trauma identificado foi a lesão por queda mecânica (104; 37,9%). O traumatismo cranioencefálico foi o tipo de trauma mais frequente observado, acometendo 174 (65,4% dos pacientes). No total, 44 (16,1%) crianças foram operadas. Cinco crianças (1,8%) morreram durante o período desta avaliação epidemiológica. Conclusão: O mecanismo de trauma pediátrico mais frequente foi a queda mecânica, a lesão mais comum foi o traumatismo cranioencefálico, as crianças do sexo masculino foram mais afetadas do que as do sexo feminino. A avaliação focada com ultrassonografia no trauma demonstrou ser um exame seguro para triagem de lesão traumática. Este estudo revelou informações importantes para futuras atualizações em protocolos de trauma pediátrico.

Purpose: To describe the epidemiology of pediatric patients admitted to a trauma center in Minas Gerais, Brazil, as well as to characterize the care received since; characterize the data from hospital admission to the propaedeutics. Methods: This is a retrospective study whose data collection took place between October 2017 and March 2018 at Hospital João XXIII. Data were collected in all children under 14 years of age who were classified as victims of trauma of "very urgent" or "emergency" according to the Manchester protocol. Descriptive analysis was performed, including the following variables: age, gender, trauma mechanism, medical specialty of the first assessment provider, need for surgical procedures, propaedeutics and death. Results: The mean age of patients was 6.9 years. The main trauma mechanism identified was mechanical fall injury (104; 37.9%). Head trauma was the most frequent type of trauma observed, affecting 174 (65.4% of patients). In total, 44 (16.1%) children were operated. Five children (1.8%) died during the period of this epidemiological assessment. Conclusion: The most frequent pediatric trauma mechanism was mechanical fall, the most common injury was traumatic brain injury, male children were more affected than females. And the physician who performed the first assessment most frequently was general surgeons. The focused evaluation with ultrasonography in trauma proved to be a safe exam for the screening of traumatic injuries. This study revealed important information to inform future updates on pediatric trauma primary assessment protocols.
