LOW-FIDELITY, LOW-COST SIMULATOR MODEL FOR VIDEOSURGERY TRAINING / MODELO DE SIMULADOR DE BAIXA FIDELIDADE E BAIXO CUSTO PARA TREINAMENTO EM VIDEOCIRURGIA

Introduction: Teaching in conventional surgery has traditionally been based on the Halstedian model of "see one, do one, and teach one". However, with the widespread success of videolaparoscopic surgery, the teaching method needed to be adapted to a novel "Do many, always mentored" model. The modern era of surgery demands sequential training with progressively increasing complexity and supervised repetition, in order to acquire specific skills prior to the first surgical procedure. Objective: To develop a new experimental teaching and training with low cost and low fidelity platform for laparoscopic surgery using synthetic materials, and simple manufacturing. Method: A platform was built using low-cost materials easily found in hardware stores, consisting of a wooden board and a few hardware materials (threaded bolt, wing nut and bolt, threaded hooks), EVA sheet (ethylene vinylacetat), white crafting paint, and felt-tip pen. The sample consisted of 15 general surgeons with more than 10 years of experience in videolaparoscopy. The evaluation began with an explanatory video lasting 20 min. Next, each surgeon performed 5 recorded tasks for later analysis and scoring. Skills were measured according to the stablished score. Results: The developed platform was useful and capable of reproducing the tasks performed based on the program of Fundaments of Laparoscopic Surgery. All the surgeons of the sample group achieved the target time proposed for the program. Conclusion: Was shown that the proposed platform can be built using easily obtainable and low-cost materials, and it proved to be an effective model for training in laparoscopic surgery, being easy to replicate and construct. Additionally, this platform can be easily adapted to various models of tasks using materials similar to those found in other training programs, that are widely practiced and have been globally validated.

Introdução: O ensino em cirurgia convencional foi tradicionalmente baseado no modelo halstediano do "see one, do one and teach one" (veja um, faça um e ensine um); porém, com a bem sucedida propagação da cirurgia videolaparoscópica precisou ser adaptado para um novo modelo do "do many, mentored always" (fazer vários, sempre supervisionado). A nova era da cirurgia demanda treinamento sequencial, com crescente complexidade e repetição supervisionada para adquirir habilidades especificas prévias ao primeiro ato operatório. Objetivo: Desenvolver modelo para ensino e treinamento em videocirurgia com plataforma de baixo custo, fácil execução e baixa fidelidade com tarefas que utilizam materiais sintéticos. Método: Construiu-se com materiais de baixo custo plataforma utilizando apenas placa de madeira, poucos materiais de ferragem (parafuso simples, parafuso com porca tipo borboleta, gancho com rosca), folha de EVA (etileno acetato de vinila), tinta branca para artesanato e caneta hidrográfica. A amostra-teste foi composta por 15 cirurgiões gerais com mais de 10 anos de experiência em videolaparoscopia. Iniciou-se a avaliação com um vídeo explicativo com duração de 20 min. A seguir, cada cirurgião executou 5 tarefas gravadas para posterior análise e pontuação. Mediu-se as habilidades de acordo com a pontuação. Resultados: A plataforma foi útil e eficaz em reproduzir as atividades utilizadas para replicação do programa comparativo do Fundaments of Laparoscopic Surgery. A amostra de cirurgiões atingiu o tempo alvo definido como padrão pelo programa. Conclusão: A plataforma elaborada com materiais de baixo custo é de fácil aquisição, mostrou-se modelo eficaz para treinamento em videocirurgia, de fácil replicabilidade e construção, adaptável a vários modelos de tarefas, e feita com materiais sintéticos.

Performance and outcome of ressucitative thoracotomies in a southern Brazil trauma center: a 7-year retrospective analysis.

OBJECTIVE: the study aims to analyze the performance and outcome of resuscitation thoracotomy (TR) performed in patients victims of penetrating and blunt trauma in a trauma center in southern Brazil during a 7 years period. METHODS: retrospective study based on the analysis of medical records of patients undergoing TR, from 2014 to 2020, in the emergency service of the Hospital do Trabalhador, Curitiba - Paraná, Brazil. RESULTS: a total of 46 TR were performed during the study period, of which 89.1% were male. The mean age of patients undergoing TR was 34.1±12.94 years (range 16 and 69 years). Penetrating trauma corresponded to the majority of indications with 80.4%, of these 86.5% victims of gunshot wounds and 13.5% victims of knife wounds. On the other hand, only 19.6% undergoing TR were victims of blunt trauma. Regarding the outcome variables, 84.78% of the patients had declared deaths during the procedure, considered non-responders. 15.22% of patients survived after the procedure. 4.35% of patients undergoing TR were discharged from the hospital, 50% of which were victims of blunt trauma. CONCLUSION: the data obtained in our study are in accordance with the world literature, reinforcing the need for a continuous effort to perform TR, respecting its indications and limitations in patients victims of severe penetrating or blunt trauma.

Epidemiological analysis of cardiac trauma victims at a referral trauma hospital: a 5 year case series.

OBJECTIVE: to describe, analyze, and trace the epidemiological profile for cardiac trauma victims on a referral trauma hospital of a major urban center. METHODS: a case series study to review, describe, compile and analyze medical records of all patients sustaining traumatic cardiac injuries, from January 2015 to January 2020 admitted to the referral trauma hospital of Curitiba, Brazil. Patients sustaining traumatic heart injuries were identified using the hospitals database. Patients who died prior to reaching hospital care were excluded. RESULTS: all 22 cases were urban victims, mostly penetrating injuries (12 stab wounds, 9 gunshot wounds); 82% were male; mean age, 37.1 years. 17 cases (77%) occurred during night hours, 15 between Friday and Sunday, and 15 were admitted hemodynamically stable. Only 27% were diagnosed with FAST, the remainder requiring other imaging exams. About incisions, 14 had thoracotomies, 6 median sternotomies and in 2 cases both. Of injuries, 8 affected the right ventricle, 3 right atrium, 9 left ventricle, 1 right coronary sulcus and 1 anterior wall. All had cardiorrhaphy repair. 3 patients died, 17 were discharged and 2 were transferred. 17 received postoperative echocardiograms, revealing ejection fractions ranging 55.1% to 75%. Patients spent a mean of 9.6 days on ICU and a mean of 15.2 days of total hospital stay. The mortality rate was 14%. CONCLUSIONS: cardiac traumas predominantly occurred in adult males, due to violent causes, during night hours on weekends. The overall mortality rate found (14%), as well as total hospital stay, accords with the literature.

Splenic infarction as a complication of covid-19 in a patient without respiratory symptoms: A case report and literature review.

INTRODUCTION: Multiple studies suggest that SARS-CoV-2 infection is associated with a pro-thrombotic state and thrombotic events have been recorded in several organs and systems. We report a patient with no respiratory symptoms, presented with abdominal pain and an extensive splenic infarction after COVID-19. CASE REPORT: A 67 year-old man was admitted to the emergency department with a moderate, dull, left-sided abdominal pain. The patient denied respiratory symptoms but referred contact with family members positive for COVID-19. He tested positive for COVID-19 and had increased D-dimer levels. Imaging studies revealed splenic infarcts and ground-glass opacities in bilateral pulmonary bases. He was treated with full-dose anticoagulation and was discharged home on oral Rivaroxaban. DISCUSSION: Although rare in the literature, cases of acute abdomen in COVID-19 patients associated with vascular infarctions have increased. Coagulopathy may be present even without clinical respiratory manifestations of the disease. Patients meeting disseminated intravascular coagulation criteria or with markedly elevated D-dimer may benefit from anticoagulant therapy. CONCLUSION: Clinicians should suspect of abdominal visceral infarctions in COVID-19 patients presented with acute abdominal pain, despite the absence of respiratory symptoms.

Psychological aspects and quality of life in Medical Residency. / Aspectos psicológicos e qualidade de vida na Residência Médica.

OBJECTIVE: to evaluate the perception of quality of life among residents in the first year of Medical Residency compared to the one among residents in other years of training, given the importance of this issue in health. METHODS: a comparative and cross-sectional analytical study performed from February to April 2016 in a reference tertiary trauma hospital in Brazil. Resident physicians were voluntarily submitted to an online questionnaire on quality of life (called WHOQOL-BREF), validated by World Health Organization (WHO). They were divided into two groups: first year of residency (R1) and other years of residency. RESULTS: ninety-seven residents of several medical specialties answered the questionnaire. Of these, 59 were men and 38 were women. The mean age was 27.7 years. First-year residents accounted for 49.5% of the interviewees. Overall, quality of life was considered regular in both groups. In relation to psychological domain, there was a significant difference between the R1 group (with worse scores in this domain) and the non-R1 group (p<0.0000001). CONCLUSION: first-year residents' quality of life is worse than the one of the residents from other years, having a significant variation of positive feelings, learning capacity, memory, thought and concentration, self-esteem, body image and appearance, and negative feelings.

Influence of trauma origin site on admission rates of patients submitted to emergency laparotomy. / Influência do local de origem do trauma nos índices de admissão de pacientes submetidos à laparotomia de emergência.

OBJECTIVE: to evaluate the influence of the site of trauma occurrence on the trauma scores of patients submitted to emergency laparotomy. METHODS: this is a retrospective, observational, analytical study. We included 212 patients who underwent exploratory laparotomies in the period of January 2015 and December 2017. We obtained information about the accident site and vital data of the patients based on data collection through electronic and physical records. We analyzed the trauma indices of patients from Curitiba and its Metropolitan Region and the place where the patient was rescued (physical establishment or public road). RESULTS: among the 212 patients studied, 184 (86.7%) were brought by the Prehospital Care Service from the city of Curitiba, and 28 (13.3%), from the Metropolitan Region of Curitiba. Twenty-five patients (17.6%) were rescued in physical establishments, while 117 (82.4%) were rescued on public roads. We observed higher values ​​of Injurity Severity Scores (ISS) in patients coming from the Metropolitan Region than in those coming from Curitiba (29.78 vs 22.46, P=0.009), but higher values ​​of Trauma and Injury Severity Scores (TRISS) in patients from Curitiba than the ones from the Metropolitan Region (90.62 vs 81.30, P=0.015). Patients rescued in public roads presented lower Revised Trauma Scores (RTS) (6.96 vs 7.65, P=0.024) and TRISS (86.42 vs 97.21; P=0.012). CONCLUSION: trauma victims from sites more distant from the referral center and rescued on public roads presented worse prognosis.

Risk factors for mortality in blunt abdominal trauma with surgical approach.

OBJECTIVE: identify risk factors for mortality in patients who underwent laparotomy after blunt abdominal trauma. METHODS: retrospective study, case-control, which were reviewed medical records of blunt trauma victims patients undergoing laparotomy, from March 2013 to January 2015, and compared the result of the deaths group with the group healed. RESULTS: of 86 patients, 63% were healed, 36% died, and one patient was excluded from the study. Both groups had similar epidemiology and trauma mechanism, predominantly young adults males, automobilistic accident. Most cases that evolved to death had hemodynamic instability as laparotomy indication - 61% against 38% in the other group (p=0.02). The presence of solid organ injury was larger in the group of deaths - 80% versus 48% (p=0.001) and 61% of them had other associated abdominal injury compared to 25% in the other group (p=0.01). Of the patients who died 96% had other serious injuries associated (p=0.0003). Patients requiring damage control surgery had a higher mortality rate (p=0.0099). Only one of 18 patients with isolated hollow organ lesion evolved to death (p=0.0001). The mean injury score of TRISS of cured (91.70%) was significantly higher than that of deaths (46.3%) (p=0.002). CONCLUSION: the risk factors for mortality were hemodynamic instability as an indication for laparotomy, presence of solid organ injury, multiple intra-abdominal injuries, need for damage control surgery, serious injury association and low index of trauma score.

RESUMOObjetivo:identificar fatores de risco para óbito em pacientes submetidos à laparotomia exploradora após trauma abdominal contuso.Métodos:estudo retrospectivo, caso-controle, no qual foram revisados prontuários dos pacientes vítimas de trauma contuso submetidos à laparotomia. Foram avaliados: variáveis epidemiológicas, mecanismo de trauma, lesões anatômicas das vísceras abdominais, lesões associadas, necessidade de operação para controle de danos reoperação e desfecho.Resultados:dos 86 pacientes, 63% foram curados, 36% foram a óbito e um paciente foi excluído do estudo. Ambos os grupos possuíam epidemiologia e mecanismo de trauma semelhantes, predominantemente adultos jovens do sexo masculino, vítimas de acidente automobilístico. A maioria dos casos que evoluíram a óbito teve instabilidade hemodinâmica como indicação de laparotomia - 61% contra 38% do outro grupo. A presença de lesão de víscera maciça foi maior no grupo óbitos - 80% vs. 48%, e 61% destes tinham outra lesão abdominal associada contra 25% dos curados. Dos pacientes que faleceram, 96% apresentavam lesões graves associadas. Pacientes que necessitaram de cirurgia de controle de danos tiveram maior taxa de mortalidade. Apenas um de 18 pacientes com lesão de víscera oca isolada evoluiu a óbito. A média do escore de trauma TRISS dos curados (91,7%) foi significativamente maior do que a dos óbitos (46,3%).Conclusão:os fatores de risco para óbito encontrados para vítimas de trauma abdominal fechado que necessitam de laparotomia exploradora são: instabilidade hemodinâmica como indicação para laparotomia, presença de lesão de víscera maciça, múltiplas lesões intra-abdominais, necessidade de cirurgia de controle de danos, lesões graves associadas e índice de trauma baixo.

Epidemiological profile of work-related accidents with biological exposure among medical students in a surgical emergency room.

OBJECTIVE: To evaluate the accidents with biological material among medical students interning in a trauma emergency room and identify key related situations, attributed causes and prevention. METHODS: we conducted a study with a quantitative approach. Data were collected through a questionnaire applied via internet, with closed, multiple-choice questions regarding accidents with biological material. The sample comprised 100 students. RESULTS: thirty-two had accidents with biological material. Higher-risk activities were local anesthesia (39.47%), suture (18.42%) and needle recapping (15.79%). The main routes of exposure to biological material were the eyes or mucosa, with 34%, and syringe needle puncture, with 45%. After contamination, only 52% reported the accident to the responsible department. CONCLUSION: The main causes of accidents and routes of exposure found may be attributed to several factors, such as lack of training and failure to use personal protective equipment. Educational and preventive actions are extremely important to reduce the incidence of accidents with biological materials and improve the conduct of post-exposure. It is important to understand the main causes attributed and situations related, so as general and effective measures can be applied.

Guidelines for discharge: do standardized cards help in patient understanding?

OBJECTIVE: To determine whether the addition of discharge standard illustrated cards improves understanding of patients in the emergency room. METHODS: We conducted a prospective, randomized, interventional study with 228 patients discharged from the emergency department. All patients were interviewed and tested for the level of understanding of discharge instructions. Some of them received the intervention, with the standard cards, and another did not, constituting the control group. RESULTS: The average of followed discharge guidelines of the group that received the cards was higher than the control group, with statistical significance (p=0.009). When segregated by age, the group between 16 and 35 years of both sexes had the best average of followed guidelines, statistically, than the average of the control group (p=0.01). The difference between the mean orientations between the control group and the card for patients undergoing procedures was statistically significant (p=0.02); as for the stratification according to the number of procedures, the significance increases when that is equal to 1 (p=0.001) and decreased the more procedures were carried out. CONCLUSION: The introduction of discharge standard orientation cards was associated with improvement in the understanding of patients. Without replacing the verbal directions, which establishes dialogue and doctor-patient bonding, cards appear as auxiliary elements, facilitating understanding and care guidelines.

Orientações de alta: cartões padronizados ajudam na compreensão dos pacientes do pronto socorro? / Guidelines for discharge: do standardized cards help in patient understanding?

OBJETIVO: determinar se a adição de cartões padronizados de alta ilustrados melhora a compreensão dos pacientes do pronto socorro. MÉTODOS: estudo prospectivo, randomizado e intervencionista com uma amostra de 228 pacientes que receberam alta do pronto socorro. Todos os pacientes foram entrevistados e testados quanto ao grau de compreensão das orientações de alta, sendo que uma parte havia recebido a intervenção com cartões padronizados e outra não, constituindo o grupo controle. RESULTADOS: a média de orientações domiciliares do grupo que recebeu o cartão de alta foi superior ao do grupo controle, com significância estatística de p=0,009. Se fracionado tal dado segundo faixas etárias, aquela compreendida entre 16 e 35 anos, para ambos os sexos, foi a qual a média de orientações do grupo com o cartão é melhor, estatisticamente, do que a média do grupo controle (p=0,01). A diferença entre as médias de orientações entre o grupo controle e o cartão para os pacientes submetidos a procedimentos foi significativa estatisticamente (p= 0,02) e em uma estratificação segundo o número de procedimentos, a significância aumenta quando aquele é igual a 1 (p=0,001) e diminui quanto mais procedimentos são realizados. CONCLUSÃO: A instituição de cartões de alta padronizados foi associada com a melhoria na compreensão dos pacientes. Sem substituir as orientações verbais, que estabelecem o diálogo e a aproximação médico-paciente, os cartões figuram como elementos auxiliares, facilitando as orientações e entendimento do cuidado.

Mesenteric thrombosis in patient victim of blunt abdominal trauma with fatal outcome / Trombose mesentérica em vítima de trauma abdominal fechado com desfecho fatal

BACKGROUND: Mesenteric thrombosis related to trauma is an uncommon entity and has poor prognosis when have low flow and hemorrhagic shock. It usually presents with a challenging diagnosis and high mortality rates, despite appropriate treatment. CASE REPORT: Patient with blunt trauma was admitted and initial treatment, complementary exams showed ribs and humerus fractures. Computerized tomography showed aerial distension in small bowels along with gastric stasis and hidropneumothorax. The patient had hypotension during clinical observation and cardiopulmonary arrest, responding to reanimation. Taken to surgery for damage control, it was found extensive necrosis of right colon, which was excised and performed primary anastomosis. He was admitted in the intensive care unit, evolving with oliguria, miosis, convulsion, and pulseless electric activity, dying three days after hospital admission. CONCLUSION: Although uncommon, mesenteric ischemia with venous thrombosis might be secondary to systemic hypotension, frequently followed by fatal outcomes.

INTRODUÇÃO: Trombose mesentérica, relacionada a trauma é entidade incomum, com pobre prognóstico quando seguida de estados de baixo fluxo e choque hipovolêmico. Geralmente apresenta-se com quadro de difícil diagnóstico, cuja mortalidade é elevada a despeito de tratamento adequado. RELATO DO CASO: Paciente submetido a trauma, após admissão hospitalar e atendimento inicial, exames radiológicos demonstraram fratura de costela e úmero. Tomografia computadorizada evidenciou distensão aérea em intestino delgado associada à estase gástrica e hidropneumotórax. O paciente evoluiu com hipotensão durante o período de observação clínica e parada cardiorrespiratória que respondeu à reanimação. Levado para operação para controle de danos, encontrou-se extensa necrose de cólon ascendente. Realizou-se hemicolectomia direita com íleotransversostomia. Levado à unidade de terapia intensiva, evoluiu com oligúria, miose, convulsão e atividade elétrica sem pulso, falecendo três dias após dar entrada no hospital. CONCLUSÃO: Embora incomum, isquemia mesentérica com trombose venosa pode ser secundária à hipotensão sistêmica, com desfecho fatal.

Fatores prognósticos relacionados à falha do tratamento não-operatório de lesões esplênicas no trauma abdominal fechado / Prognostic factors related to non surgical treatment failure of splenic injuries in the abdominal blunt trauma

Objetivo: Identificar fatores prognósticos relacionados com a falha do tratamento não-operatório (TNO) de lesões esplênicas no trauma abdominal fechado. Métodos: Análise prospectiva de 56 pacientes adultos submetidos à TNO e divididos em um grupo de sucesso e outro de falha, que foi definida como necessidade de laparotomia por qualquer indicação. As lesões foram diagnosticadas por tomografia computadorizada e classificadas de acordo com os critérios da AAST (American Association for Surgery of Trauma). Os parâmetros estudados foram: na admissão - pressão arterial sistólica, frequências cardíaca e respiratória, nível de consciência (Escala de Glasgow) e RTS (Revised Trauma Score); durante a hospitalização – presença de lesões associadas, transfusão sanguíneae parâmetros hematológicos, tempo de internação e ISS (Injury Severity Score). Resultados: As falhas do TNO (19,6%) foram devidas à dor abdominal (45,4%), instabilidade hemodinâmica (36,4%), queda do volume globular associada a hematoma esplênico (9,1%) e abscesso esplênico (9,1%). Não foram observadas diferenças entre os grupos de sucesso e de falha nos dados na admissão. A taxa de falha de acordo com o grau da lesão esplênica foi 0% nos graus I e II agrupados; 17,5% nos graus III e IV agrupados e 80%no grau V (p = 0,0008). O uso de hemoderivados foi maior e mais frequente no grupo de falha (p=0,05). As relação do ISS (Injury Severity Score) com as taxas de falha foram 0% nos pacientes com ISS = 8; 15,9% nos com ISS entre 9 e 25, e 50% nos com ISS = 26 (p = 0,05). Não houve mortalidade e nem lesões de vísceras ocas despercebidas. Conclusão: O Injury Severity Score e grau da lesão esplênica relacionaram-se com a falha do tratamento não-operatório.

Objective: Identify prognostic factors related to treatment failure of blunt splenic injuries managed by non surgical treatment (NST). Methods: Fifty six adult patients submitted to NST were prospectively studied. The injuries were diagnosed by computed axial tomography scan and classified according to AAST (American Association for Surgery of Trauma) criteria. Patients were divided in success and failure groups. NST failure was defined as the need for laparotomy for any reason. Results: NST failures (19.6%) were due to: abdominal pain (45.4%), hemodinamic instability (36.4%), splenic haematoma associated to a fall in hematocrit (9.1%) and splenic abscess (9.1%). There were no failures in grade I and II of the splenic injuries; failure rate was 17.5% in grade III and IV injuries grouped, and 80% in grade V injuries (p = 0,0008). In the success group, 31.3% patients received red cell transfusions, versus 63.6% patients in the failure group (p = 0,05). Failure rate in patients with ISS = 8 was zero; 15.9% in patients with ISS 9 to 25; and 50% in patients with ISS = 26 (p = 0,05). There were no deaths or missed bowel injuries. Conclusion: ISS and splenic injury grade were related to failure of NST.
