Abstract: Introduction: burns are a serious public health problem, with several studies estimating that more than 11 million people were affected by burn injuries with approximately 300,000 deaths worldwide. Studies showed that the main causes of death were inhalation injuries, infection, and metabolic and hemodynamic complications ending in multi-organ failure. It has been shown that the increase in the systemic inflammatory response, whose parameters can be easily obtained, can be useful and directly related to poor prognosis. Several clinical studies indicate that the ratio of neutrophils to lymphocytes, an indicator of systemic inflammatory response, can signify the presence of inflammation in some diseases such as diabetes, coronary artery disease, cholangitis, rheumatoid arthritis, and recently COVID-19. Objective: to know the association between the neutrophil lymphocyte index as a biomarker of mortality in patients with major burns. Material and methods: an observational, retrospective, descriptive, longitudinal study will be carried out: with a user population of the National Center for Research and Attention to Burned Patients (CENIAQ) of the Luis Guillermo Ibarra Ibarra National Rehabilitation Institute. A review of the clinical records of the patients treated in the period will be carried out during the period from February 1, 2020 to February 28, 2022, the data of admission and discharge will be taken into account, as well as initial laboratory studies. The information will be recorded in an Excel spreadsheet to be later analyzed in the SPSS software, the results will be obtained and finally their analysis will be carried out. Results: in the analyzed population we found that the average age is 40 years, it was also found that the most affected gender in this population corresponds to the male gender with 81.2%. It was also found that, within the diagnoses of the population studied, fire burn was the one that most affected the population, this being 67.1% of all diagnoses. However, in this study no significant difference was found in the neutrophil lymphocyte index with respect to the type of burn. In our analysis, the neutrophil lymphocyte index was included as a biochemical predictor of mortality, since high levels of this index at admission are associated with increased mortality. In our population, a significant difference was found between the groups with a fatal clinical outcome and those who recovered, which is why it can be considered as a predictor of mortality in these patients since they presented a p value < 0.023, data that is consistent with what is reported in the international literature where the Neutrophil lymphocyte index value can be used as a predictor of mortality. Conclusions: an association was found between the elevation of the neutrophil/lynphocyte ratio and mortality in patients with severe burns.

Resumo: Introdução: as queimaduras são um grave problema de saúde pública, onde estima-se em diversos estudos que mais de 11 milhões de pessoas foram acometidas por queimaduras com aproximadamente 300.000 mortes em todo o mundo. Estudos mostraram que as principais causas de morte foram lesões inalatórias, infecções e complicações metabólicas e hemodinâmicas que culminaram em falência de múltiplos órgãos. Tem sido demonstrado que o aumento da resposta inflamatória sistêmica, cujos parâmetros podem ser facilmente obtidos, pode ser útil e estar diretamente relacionado ao mau prognóstico. Vários estudos clínicos indicam que a proporção de neutrófilos para linfócitos, um indicador de resposta inflamatória sistêmica, pode significar a presença de inflamação em algumas doenças como diabetes, doença arterial coronariana, colangite, artrite reumatóide e recentemente COVID-19. Objetivo: conhecer a associação entre o índice neutrófilo-linfócito como biomarcador de mortalidade em pacientes com grandes queimaduras. Material e métodos: será realizado um estudo observacional, descritivo, retrospectivo, longitudinal: com a população usuária do Centro Nacional de Pesquisa e Atenção ao Paciente Queimado (CENIAQ), do Instituto Nacional de Reabilitação Luis Guillermo Ibarra Ibarra. Realizaremos uma revisão dos prontuários clínicos dos pacientes atendidos no período de 1º de fevereiro de 2020 a 28 de fevereiro de 2022, serão levados em consideração os dados de admissão e alta, bem como os estudos laboratoriais iniciais. As informações serão registradas em planilha Excel para posteriormente serem analisadas no software SPSS, serão obtidos os resultados e por fim será realizada a análise. Resultados: na população analisada verificamos que a média de idade é de 40 anos, constatou-se também que o gênero mais acometido nesta população corresponde ao gênero masculino com 81.2%. Constatou-se também que, dentro dos diagnósticos da população estudada, a queimadura por fogo foi o que mais afetou a população, sendo este 67.1% do total de diagnósticos. No entanto, neste estudo não foi encontrada diferença significativa no índice neutrófilo-linfócito em relação ao tipo de queimadura. Em nossa análise, foram incluídos o índice neutrófilo-linfócito como preditor bioquímico de mortalidade, uma vez que altos níveis desse índice na admissão estão associados a aumento da mortalidade. Em nossa população, foi encontrada diferença significativa entre os grupos com desfecho clínico fatal e os recuperados, motivo pelo qual pode ser considerado como preditor de mortalidade nesses pacientes, pois apresentaram valor de p < 0.023, dado compatível com o relatado em a literatura internacional onde o valor do índice neutrófilo-linfócito pode ser utilizado como preditor de mortalidade. Conclusões: encontrou-se associação entre a elevação do índice neutrófilo/linfócito e mortalidade em pacientes com queimaduras graves.

Registro Nacional de Quemados Chile: presentación de una plataforma online y mirada al pronóstico de pacientes no trasladados a Centro de Quemados / Presentation of an online National Registration Platform for severely burned patients in the Chilean Public Health System and a look into the prognosis of patients not transferred to the National Reference Burn Center

Resumen Introducción: En el año 2017 se incorporó un registro de notificación en línea (Registro Nacional de Quemados) al flujo de derivación de pacientes quemados en Chile. Objetivo: A partir de la información obtenida de esta plataforma, se describe la epidemiología de las quemaduras y las variables que podrían explicar los traslados fallidos a nuestra unidad de quemados. Materiales y Método: Se analizaron los casos subidos a esta plataforma entre julio de 2017 y julio de 2018. Se caracterizó la población global y comparó variables relevantes entre el grupo de pacientes no trasladados a nuestra unidad y los que fueron trasladados con éxito. Resultados: Se analizaron 319 pacientes, 66% hombres, edad promedio 51 años, IMC de 27% y 47% con enfermedades previas. El fuego fue la principal causa de quemaduras. Se observó un 31% de injuria inhaladora. 107 pacientes no se trasladaron a nuestro centro de quemados. Los pacientes trasladados puntuaron más alto en comorbilidad, índice de gravedad, superficie corporal total quemada y aseo quirúrgico en el hospital base. El grupo de pacientes no trasladados puntuó más alto en injuria inhalatoria. La mortalidad global fue 20,4%. La mortalidad fue mayor en pacientes no trasladados (33,6% versus 13,7%; p < 0,001). Conclusiones: Además de facilitar el flujo de pacientes y ahorrar recursos, un uso noble de esta plataforma es ser fuente de información epidemiológica y de implementación de políticas públicas, lo cual puede ser tomado como ejemplo por otros países en vías de desarrollo. Además, se demuestra que ser trasladado constituye un factor protector de muerte por quemaduras.

Introduction: In 2017, an online notification register, the National Burn Registry, was incorporated into the referral flow of burned patients in Chile. Aim: Through the information obtained from this platform, we describe the epidemiology of burns in Chile, and identify variables that could explain failed transfers to our burn unit. Materials and Method: Cases uploaded to this platform between July 2017 - July 2018 were analyzed. We characterize the global population and relevant variables were compared between the group of patients that failed to be transferred to the burn unit and the ones who were successfully transferred. Results: 319 patients were analyzed, 66% men, average age 51 years, BMI of 27 and 47% with previous illnesses. Fire was the main cause of burn injury. Smoke inhalation injury was observed for 31%. 107 patients failed to reach to our burn center. Transferred patients rated higher in comorbidity, severity index, total burned body surface and surgical debridement at base hospital. The group of not transferred patients rated higher in inhalation injury. Overall mortality was 20.4%. Mortality was higher in non-transferred patients (33.6% versus 13.7%; p < 0.001). Conclusions: Aside from facilitating the flow of burned patients and resources saving, a noble use of this platform has been to serve as a source of epidemiological information and implementation of public policies, which can be taken as an example by other developing countries. Also, being transferred is a protective factor for death from burn injuries.

Resultados de la implementación de un protocolo de soporte nutricional en grandes quemados pediátricos internados en la Unidad de Cuidados Intensivos / Results of the implementation of a nutritional support protocol for major burn pediatric patients hospitalized in the Intensive Care Unit

Introducción: "Gran quemado" es quien sufre lesiones por daño térmico que afectan más del 30% de su superficie corporal (SC). El hipercatabolismo secundario causa pérdida de masa magra y retraso de la cicatrización de heridas. Objetivo: Describir y analizar los resultados de la implementación de un protocolo de soporte nutricional en niños quemados graves internados en una Unidad de Cuidados Intensivos durante las primeras 6 semanas evolutivas. Población y métodos: Diseño analítico, prospectivo, observacional y longitudinal. Se midieron peso, talla, porcentaje de SC quemada, días de internación en la Unidad de Cuidados Intensivos y mortalidad. Se analizaron tasa metabólica basal por calorimetría indirecta y fórmula de Schofield, cobertura de aporte energético y proteico, prealbúmina, proteína C reactiva, vitaminas A, D, E, cobre y zinc semanales. Resultados: Se incluyeron 18 pacientes (media: 3,9 años, 49% de SC quemada). Se alcanzó la media de objetivo energético en la segunda semana y el requerimiento proteico en la semana 6. Doce pacientes requirieron nutrición parenteral complementaria sin complicaciones. Se hallaron parámetros de hipermetabolismo, que se normalizaron a las 4-6 semanas del ingreso, excepto la proteína C reactiva. Las vitaminas A y E y elementos traza (zinc y cobre) estaban descendidos al ingreso con mejoría posterior. La vitamina D persistió en valores bajos. Un paciente falleció. Conclusiones: La implementación del protocolo permitió lograr el aporte de la totalidad del requerimiento energético; la cobertura del requerimiento proteico se postergó hasta la semana 6. Es necesario hacer hincapié en resolver las limitaciones para alcanzar este último.

Introduction. "Major burn" is used to describe a person who suffers thermal damage affecting more than 30% of his/her total body surface area (TBSA). The secondary hypercatabolism causes lean body mass loss and delayed wound healing. Objective. To describe and analyze the results of implementing a nutritional support protocol for pediatric burn patients hospitalized in the intensive care unit in the first 6 weeks. Population an d methods. Analytical, prospective, observational, and longitudinal design. Weight, height, %TBSA, length of stay in the intensive care unit, and mortality were measured. The basal metabolic rate was measured by indirect calorimetry and the Schofield equation, and protein and energy intake, prealbumin, C-reactive protein, vitamins A, D, E, copper, and zinc levels were analyzed every week. Results. Eighteen patients were included (mean: 3.9 years old, 49%TBSA). The mean energy target was achieved by week 2 and protein requirements were met by week 6. Twelve patients required complementary parenteral nutrition and there were no complications. Hypermetabolism parameters were observed, which returned to normal 4-6 weeks after hospitalization, except for C-reactive protein. Vitamins A and E and trace elements (zinc and copper) were reduced at the time of admission and showed a subsequent improvement. Vitamin D remained low. One patient died. Conclusions. Implementing the protocol was useful to cover the total energy requirement; the coverage of protein requirements was delayed until week 6. It is necessary to focus on solving limitations to achieve the latter.

A cross-sectional study on the relationship between stress and the level of job satisfaction among the burn unit staff of UP-PGH

OBJECTIVES: This study looked into the relationship between stress and the level of job satisfaction among the Burnt Unit staff of UP-PGH. Emphasis was placed in identifying the common stressors that the Burn Unit Staff of UP-PGH experience as a result of their day to day work in a critical care setting.The level of job satisfaction among staff was also determined.METHODOLOGY: Questionnaires assessing stress and job satisfaction were handed out to all the 31 participants of the study. The study population included 10 doctors and 21 nurses who had worked at the Burn Unit during the period of March to September 2007. Odds ratios were computed to determine if the presence of stress affects the level of job satisfaction among the Burn Unit Staff of UP-PGH. The resulting odds ratios were further tested for statistical significance using Fisher exact test and confidence limits.RESULTS: Of the 31 survey forms initially handed out to the Burn Unit staff, only 28 forms were completed and returned to the investigator at the end of the study period. Two items in the Stressful Situations Questionnaire were rated to be "stressful" by majority (>50%) of the respondents. Twenty-five percent of the respondents obtained positive scores in the Job Dissatisfaction Scale and were classified as being "dissatisfied" with their jobs. Twenty-two situations in the Stressful Situations Questionnaire were found to be significantly associated with job dissatisfaction among the Burn Unit staff of UP-PGH. These situations concerned the following areas: relationship with patients, family rejection, identification with the patient, deterioration and complications, job criticism, workspace, daily work, and therapeutic decisions.CONCLUSIONS: From the results of the study, recommendations were made to promote a system of stress-reduction for the Burn Unit staff. Regular group psychosocial processing sessions can be provided to allow the staff to ventilate their thoughts and feelings regarding personal and professional concerns. Team building activities for the staff can likewise be scheduled regularly to help solidify the group and resolve interpersonal conflicts among them. Future researchers could explore if a difference exists between the nurses and surgery residents in terms of their perceived stressors and their level of job satisfaction with their work in the Burn Unit.

Unidade de Tratamento de Queimaduras da Universidade Federal de São Paulo: estudo epidemiológico / Burn Care Unit of São Paulo Federal University: an epidemiological profile

INTRODUÇÃO: As queimaduras são traumas graves, que geram 100 mil atendimentos hospitalares por ano, no Brasil. As Unidades de Queimados são fundamentais para o tratamento desses pacientes e a produção de conhecimento sobre o tema. MÉTODO: O estudo estabeleceu o perfil de atendimento em cada ano de funcionamento da unidade no período de 2009 a 2012, e comparou, entre esses anos, a quantidade de pacientes internados, a procedência, os graus de queimadura, a idade, a superfície corporal queimada, os dias de internação, os tipos de procedimentos cirúrgicos, os agentes e a mortalidade. Para avaliação das possíveis associações, foi utilizado o teste do Qui-quadrado. RESULTADOS: Foram internados 321 pacientes. Em 2009, 70% dos pacientes apresentavam queimadura de II grau e, em 2012, 66% dos pacientes tinham queimadura de III grau. Em 2009, 37% vieram referenciados de outros serviços, e em 2012, 72%. A idade média dos pacientes foi de 29 anos em 2009 e 44 anos, em 2012. A superfície corporal queimada no início era de 13%, e em 2012, foi 8%. O tempo de internação subiu de 11 para 21 dias. Em 2009, realizaram-se 50 procedimentos cirúrgicos. Em 2012, foram 103. O agente causal mais encontrado foram os líquidos inflamáveis e a mortalidade global caiu de 7% para 4%, ao longo dos anos. CONCLUSÃO: Houve um aumento na quantidade de pacientes referenciados e complexos, com queimaduras de maior grau, exigindo mais procedimentos e maior hospitalização, ao longo dos anos. A taxa de mortalidade diminuiu, refletindo melhora técnica da Unidade, que se estabeleceu como referência regional no tratamento de queimados.

INTRODUCTION: Burns constitute severe trauma and account for 100,000 hospital visits per year in Brazil. Burns units are essential for the treatment of these patients and the generation of knowledge on this subject. METHOD: This study established the annual profile of burn unit attendance between 2009 and 2012. During these years of activity, we compared the number of hospitalized patients, patient origin, burn degree, age, burn body surface area, days of hospitalization, types of surgical procedures, agents, and mortality. Possible combinations were evaluated with the chi-square test. RESULTS: A total of 321 patients were hospitalized. In 2009, 70% of the patients presented secon-degree burns; in 2012, 66% of the patients presented third-degree burns. In 2009, 37% of the patients were referred to other services; in 2012, 72% were referred. The average patient age was 29 years old in 2009 and 44 years old in 2012. Burn body surface was 13% in 2009 and 8% in 2012. Hospitalization time increased from 11 to 21 days. A total of 50 surgical procedures were performed in 2009, while 103 were performed in 2012. Flammable liquids were the most commonly observed causal agents. The overall mortality rate decreased from 7% to 4% over the study period. CONCLUSION: There was an increase in the number of referred and complex patients with higher degree burns who required longer hospital stays and a greater number of procedures over the years. The decreased mortality rate reflected the technical improvement of the unit that was established as a regional reference for the treatment of burn victims.

Introdução: As queimaduras são lesões de grande morbidade e mortalidade que geram considerável ônus para o estado. Este estudo tem como objetivo traçar o perfil epidemiológico dos pacientes internados na Unidade de Tratamento de Queimados (UTQ) do Hospital Geral de Vila Penteado (HGVP/SP). Método: Foram analisados os dados de internações de pacientes na UTQ do HGVP, no período de Janeiro/2012 a Julho/2013, sendo avaliadas as seguintes variáveis: gênero, idade, causa e extensão da queimadura, intervalo entre queimadura/internação, tempo de internação e evolução do paciente. Resultados: Observou-se predominância das internações em homens (65,8%). Em relação à idade, houve maior concentração de queimados na população adulta (80%). O fogo foi a principal causa de lesões (58,5%), seguido pela escaldadura (19,5%); 62% das queimaduras ocorreram no domicílio e 11,5%, no trabalho. Constatou-se que a maioria das vítimas (56,1%) apresentaram queimaduras de médio e grande porte e que 46,3% dos pacientes foram admitidos nas primeiras 24 horas pós-queimaduras. Quanto ao tempo de internação, foram verificados períodos inferiores a 15 dias como sendo os de maior incidência (55,4%). Obteve-se uma taxa de altas hospitalares igual a 83%, contra uma taxa de óbitos de 17%. Conclusão: Este estudo demonstrou o perfil de queimaduras e internações na UTQ do HGVP compatível com a grande maioria dos dados de outros centros especializados, ressaltando a importância dos estudos epidemiológicos que visam à prevenção desse problema.

Introduction: Burns are injuries with major morbidity and mortality and are a considerable burden on the government. The aim of this study was to investigate the epidemiological profile of patients admitted to the burn care unit (BCU) of the Vila Penteado General Hospital (HGVP/SP). Method: The data analyzed were derived from patient admissions to the BCU of the HGVP, from January 2012 to July 2013, using the following variables: sex, age, cause and extent of the burn, time between burn/admission, estratificalength of stay, and patient's progress. Results: The majority of admissions were observed in men (65.8%). There was a greater percentage of burn patients in the adult population (80%). Fire was the main cause of injury (58.5%), followed by scalding (19.5%); 62% of burns occurred at home and 11.5% at work. Most victims (56.1%) had medium and large burns, and 46.3% of the patients were admitted in the first 24 hours after a burn. A length of stay of less than 15 days was most common (55.4%). The hospital discharge rate was 83% with a death rate of 17%. Conclusion: This study demonstrated that the epidemiological profile for burns and admissions to the BCU of the HGVP was consistent with the great majority of data from other specialty centers, and emphasizes the importance of epidemiological studies on prevention.

The mean hospital stay was of 38 days and a mortality of 3.1%.Conclusions: The number of cases of electrical burn injuries admitted at the Hospital “Luis Vernaza” and rate of disability is increasing.

Antibiotic Resistance and Genotyping of Pseudomonas aeruginosa Isolated from Burn Unit by Pulsed-field Gel Electrophoresis / 中华医院感染学杂志

OBJECTIVE To analyze antibiotic resistance pattern and use pulsed-field gel electrophoresis(PFGE) to study the molecular epidemiology of Pseudomonas aeruginosa isolated from burn unit. METHODS P.aeruginosa had been isolated and tested by K-B method from clinical samples and antibiotic resistance was analyzed and studied retrospectively. RESULTS The drug resistance of P.aeruginosa to nine antibiotics was high,the multiple drug resistance rate was 30%. CONCLUSIONS The resistance rates to commonly used antibacterials in P.aeruginosa are high and the resistance pattern is wide.PEGE is a better genotyping method to study molecular epidemiology and analytic homology.
