The potential use of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in a Brazilian hospital. / O uso potencial do Balão de Oclusão Endovascular da Aorta para Ressuscitação em um hospital brasileiro.

AIM: To evaluate the potential use of REBOA in a Brazilian hospital. METHODS: We performed a retrospective analysis of all requests for emergency surgical evaluation for patients with suspected massive hemorrhage, hospitalized in a private Brazilian general hospital, from April 1, 2017 to March 31, 2018. Inclusion criteria for REBOA eligibility were: suspected abdominal and/or pelvic bleeding, hemorrhagic shock and older than 18 years of age. Exclusion criteria were: older than 70 years of age, and pre-existing terminal disease or significant comorbidities. RESULTS: 90 evaluations were requested during the study period. However, according to our inclusion/exclusion criteria, only on 14 occasions (15.6%) there was a recommendation for the use of REBOA. Gynecological/obstetric conditions were the indication in 11 cases (78.6%) and elective oncologic surgery in three cases (21.4%). CONCLUSIONS: The use of REBOA is not common in our country, but it can be an essential tool, and perhaps the last resource in extremely severe conditions until the definitive surgical, endovascular or endoscopic treatment is performed.

OBJETIVO: Este estudo objetivou analisar o uso potencial Balão de Oclusão Endovascular da Aorta para Ressuscitação (REBOA) em um hospital brasileiro. MÉTODOS: Foi realizada uma revisão da literatura e uma análise retrospectiva de todas as avaliações cirúrgicas de emergência para pacientes com suspeita de hemorragia maciça internados em um hospital brasileiro, de 1 de abril de 2017 a 31 de março de 2018. Os critérios de elegibilidade do REBOA foram: origem abdominal e/ou pélvica, choque hemorrágico e acima de 18 anos de idade. Os critérios de exclusão foram: acima de 70 anos e doença terminal pré-existente ou comorbidades significativas. RESULTADOS: No período, foram solicitadas 90 avaliações. Em 14 ocasiões (15,6%) havia indicação para o uso do REBOA. Os casos em que isso foi possível foram devidos a causas ginecológicas/obstétricas em 11 casos (78,6%) e cirurgia oncológica eletiva em três casos (21,4%). CONCLUSÕES: O REBOA é ainda pouco utilizado em nosso país, mas pode ser uma ferramenta de extrema importância, e talvez o último recurso em pacientes extremamente graves, até que o tratamento definitivo, cirúrgico, endovascular ou endoscópico seja efetuado.

Borage oil attenuates progression of cardiac remodeling in rats after myocardial infarction.

PURPOSE: To investigate the effects of Borage oil on cardiac remodeling after myocardial infarction (MI). METHODS: Male Wistar rats underwent ligation of the left coronary artery and divided into three groups: MI (control), BO-18 (18 mg/kg of borage oil) and BO-180 (180 mg/kg of borage oil). After seven days, heart was arrested in diastole and processed for histological evaluation of: MI size, LV dilation, myocyte hypertrophy, inflammatory infiltration and fibrosis in MI region and in remote region. The relative weight of the lung was used as a marker of heart failure. The MI size was comparable among groups. RESULTS: Compared to control, BO treated groups showed lower weight of heart and lungs, reduced LV dilation and myocyte hypertrophy. Hemodynamic measurements were comparable. The treatment attenuated the inflammatory infiltration and fibrosis in remote myocardium. CONCLUSION: Borage oil attenuates progression of cardiac remodeling after myocardial infarction and congestive heart failure.

[Damage control surgery: an update]. / Cirurgia para controle de danos: estado atual.

The damage control surgery is a widely accepted concept today among abdominal trauma specialists when it comes to the severely traumatized. In these patients, the death is due, in most cases, to the installation of the lethal triad (hypothermia, coagulopathy and acidosis) and not the inability to repair the serious initial damage. In this review, the authors address the lethal triad in its three phases and emphasize the measures taken to prevent them, as well as discussing the indication and employment of damage control surgery in its various stages. Restoring the physiological status of the patient in the ICU, so that he/she can be submitted to final operation and closure of the abdominal cavity, another challenge in severe trauma patients, is also discussed.

Cirurgia para controle de danos: estado atual / Damage control surgery: an update

A cirurgia de controle de danos é um conceito amplamente aceito atualmente entre os especialistas em trauma abdominal quando se trata de doentes gravemente traumatizados. Nestes pacientes a morte decorre, na maioria das vezes, da instalação da tríade letal (hipotermia, coagulopatia e acidose) e não da incapacidade de reparar as graves lesões presentes. Nesta revisão, os autores abordam a tríade letal, em suas três fases, e enfatizam as medidas adotadas para preveni-las. Além de discutirem a indicação e o emprego da cirurgia para o controle de danos em seus vários estágios. A restauração dos padrões fisiológicos do doente na UTI, para que o mesmo possa ser submetido à operação definitiva e ao fechamento da cavidade abdominal, outro desafio no paciente traumatizado grave, também é discutida.
