Experience of non-operative management of blunt liver trauma at Hospital das Clínicas de Uberlândia: 114 cases / Experiência de tratamento não operatório de traumas hepáticos contusos no Hospital das Clínicas de Uberlândia: 114 casos

ABSTRACT Introduction: trauma is the leading cause of death for the age group from 1 to 49 years in Brazil. Non-Operative Management (NOM) is the gold standard in trauma centers and does not affect mortality in comparison to operative treatment. Methods: medical records were reviewed for 114 patients with blunt liver trauma treated at Hospital das Clínicas of the Federal University of Uberlândia (HC-UFU) from November 2015 to November 2020. Results: the most prevalent gender was masculine (74.5%). The most prevalent age group was 20 to 49 years (65.7%). The majority of admitted patients (60.5%) had an Injury Severity Score (ISS) of more than 15. On hospital admission, 30.7% had HR above 100 bpm and 30.70% had SBP below 100mmHg. NOM was implemented in 77.2% of patients, the failure rate was 11.36% and the specific failure rate, excluding complications of associated injuries that resulted in surgery, was 1.75%. One third of deaths were due to severe traumatic brain injury. Conclusion: the failure rate of NOM in this study is similar to the literature reports for liver trauma. The failure rate, excluding complications of associated injuries, is considered low. The recognition of the epidemiological profile of patients admitted at HC-UFU allows multidisciplinary and integrated care with specialized training, as well as the development of institutional protocols, aiming to reduce morbidity and mortality related to hepatic trauma.

RESUMO Introdução: o trauma é a principal causa de morte na faixa etária de 1 a 49 anos no Brasil. O Tratamento não operatório (TNO) é padrão ouro nos centros de trauma e não altera a mortalidade quando comparado ao tratamento operatório. Métodos: foram avaliados 114 prontuários médicos de pacientes vítimas de trauma hepático contuso atendidos no Hospital das Clínicas da Universidade Federal de Uberlândia (HC-UFU) no período de novembro de 2015 a novembro de 2020. Resultados: os homens foram o sexo mais acometido (74,5%) e a faixa etária mais prevalente foi de 20 a 49 anos (65,7%). 60,5% dos pacientes admitidos apresentavam um Injury Severity Score (ISS) maior ou igual a 16. Na admissão, 30,7% apresentaram FC acima de 100bpm e 30,70% PAS abaixo de 100mmHg. O TNO foi instituído em 77,2% dos pacientes, o índice de falha foi de 11,36% e o índice de falha específica, excluindo as cirurgias decorrentes por complicação de lesões associadas, foi de 1,75%. 33,33% dos óbitos foram decorrentes de traumatismo cranioencefálico grave. Conclusão: o índice de TNO instituído no HC-UFU é próximo ao estabelecido na literatura para traumas hepáticos. O índice de falha, quando excluídas às complicações por lesões associadas, é considerado baixo. O reconhecimento do perfil epidemiológico dos pacientes admitidos no HC-UFU permite o treinamento especializado integrativo e multiprofissional das equipes assistenciais e o desenvolvimento de protocolos institucionais, visando reduzir a morbimortalidade relacionada ao trauma hepático.

Abstract Objective to map evidence on deliberate practice (DP) and rapid cycle deliberate practice (RCDP) in teaching Basic Life Support (BLS) to health occupations students. Method a scoping review according to JBI Reviewer's Manual for Scoping Reviews and PRISMA-ScR. Searches and selections were carried out in the databases through descriptors and synonyms, and it was analyzed the relevance of the studies, selecting those that answered the research question, from April to November 2021. In December 2022, study search and selection were updated. Results of the 4,155 studies found, 116 were analyzed in full, with 9 included in this study. 44.4% are Americans and 66.6% were accomplished in medical courses. 11.1% presented simulated scenarios in the intra- and extra-hospital context, and 11.1%, in intra-hospital scenarios. Conclusion and implications for practice DP and RCDP in health education have been consolidated in recent years, showing improvements in learning and knowledge retention over time. This scope identified that most studies address the hospital context, which demonstrates the knowledge production gap in the pre-hospital area. Furthermore, most of the studies focused on Europe and North America, confirming the need to carry out studies for the applicability of DP and RCDP in BLS in different audiences and contexts.

Application and analysis of competition based training mode for first aid skills in residency program / 中华急诊医学杂志

Objective:To explore the model of first aid skills training based on competition.Method:The second-year residents who participated in the competition in 2021 ( n = 142) were selected. According to whether they attended BLS training in the first year, they were divided into group A ( n = 88) who attended BLS training and group B ( n = 54) who did not. Chi-square test, T test, Wilcoxon rank sum test and Logistic regression were used in our study. Results:There was no significant difference in gender and specialty between both groups (female, 62.5% vs. 68.5%, P= 0.466; TCM, 50% vs. 53.7%, P= 0.668), but the real resuscitation experience of group A was more than that of group B (40.9% vs. 9.3%, P= 0.000). The qualified rate of CPR and the compression score in group A was higher than that in group B [(81.8% vs. 61.1%, P = 0.006; (30±5) vs. (25 ±10), P= 0.001], including compression frequency, depth, rebound and compression/respiration rate (73.9% vs. 55.6%, P= 0.024; 88.6% vs. 70.4%, P= 0.006; 96.6% vs. 87%, P= 0.031). In the theoretical examination, the correct rates of electrocardiogram [(53.63±2.9)% vs. (50.44±2.57)%] and first aid medication [(57.38±3.55)%, P = 0.001] in the two groups were significantly lower than the qualified rate. After adjusting other factors, Logistic regression analysis showed that the CPR qualification rate in group A was 2.769 times higher than that in group B ( P= 0.015, 95% CI 1.215~6.311) Conclusions:The first aid skills training mode based on competition can objectively reflect first aid skills level of residents. We found that the quality of CPR skills was not related to gender, specialty and real CPR experiences but experience of BLS training was an independent influencing factor. And how to identify and manage arrhythmias and how to choose different emergency drugs are urgent emergency skills for residents to improve.

Resumen: Objetivo: determinar las características y desenlaces clínicos de pacientes menores de 18 años tratados con oxigenación con membrana extracorpórea (ECMO) posterior a cirugía para la reparación o paliación de cardiopatías congénitas en un centro de referencia del suroccidente colombiano entre 2015 y 2020. Método: estudio descriptivo longitudinal con recolección retrospectiva de la información. Resultados: entre enero de 2015 y diciembre de 2020, 77 pacientes requirieron ECMO posterior a cirugía cardiaca pediátrica, con una mediana de edad de < 1 mes, mediana de peso de 4 kg, tiempo de circulación extracorpórea de 202 minutos y tiempo de pinzamiento aórtico de 95 minutos. La cardiopatía congénita más ingresada a ECMO fue el síndrome de corazón izquierdo hipoplásico (19.4%) en su posquirúrgico de Norwood (18.1%). La mediana del tiempo de ECMO fue de 111 horas. La indicación más frecuente fue la disfunción ventricular (80.5%). El 80.5% presentó complicaciones y la reintervención por sangrado fue la más frecuente (46.7%). La sobrevida a la ECMO fue del 48% y la sobrevida general al momento del alta fue de 25.97%. La edad < 1 mes (p = 0.030), el ácido láctico preECMO ≥ 5 mmol/l (p = 0.014) y el tiempo de normalización del lactato ≥ 24 horas (0.021), se asociaron a un mayor riesgo de mortalidad al egreso hospitalario. Conclusiones: la ECMO proporciona un soporte adecuado posterior a la cirugía cardiaca pediátrica. La edad < 1 mes, el ácido láctico preECMO ≥ 5 mmol/L y el tiempo de normalización del lactato ≥ 24 horas fueron las variables que se asociaron con un mal resultado y mortalidad hospitalaria.

Abstract: Objective: to determine the characteristics and clinical outcomes of patients under 18 years of age treated with extracorporeal membrane oxygenation (ECMO) after surgery for the repair or palliation of congenital heart disease. Method: longitudinal descriptive study with retrospective data collection. Results: between January 2015 and December 2020, 77 patients required ECMO after pediatric cardiac surgery with a median age of < 1 month, median weight of 4 kg, ECC time 202 minutes (IQR 125-272 minutes), aortic cross-clamp time 95 minutes. 76.6% were supported with ECMO prior to their return to the ICU. The congenital heart disease most frequently admitted to ECMO was hypoplastic left heart syndrome (19.4%) in the Norwood postoperative period (18.1%). The median time of ECMO was 111 hours. The most frequent indication was ventricular dysfunction (80.5%). 80.5% presented complications and reoperation for bleeding was the most frequent of these (46.7%). ECMO survival was 48% and overall survival at discharge was 25.97%. Age < 1 month (p = 0.030), pre-ECMO lactic acid ≥ 5 mmol/l (p = 0.014), OR 0.260 and time of normalization of lactate ≥ 24 hours (0.021), OR 0.24 were associated with a higher risk of mortality at hospital discharge. Conclusions: ECMO provides adequate support after surgery for the repair or palliation of congenital heart disease. Age < 1-month, pre-ECMO lactic acid ≥ 5 mmol/l, and lactate normalization time ≥ 24 hours were the variables that were associated with poor outcome and hospital mortality.

De un centro de trauma a un sistema de trauma en el suroccidente colombiano / From a Trauma Center to a Trauma System in Southwest Colombia

Introducción. El objetivo de este estudio fue evaluar el impacto sobre la mortalidad según el perfil de ingreso a un centro de trauma del suroccidente colombiano, como método para entender las dinámicas de atención del paciente con trauma. Métodos. Se realizó un subanálisis del registro de la Sociedad Panamericana de Trauma asociado a un centro de trauma en el suroccidente colombiano. Se analizaron los pacientes atendidos entre los años 2012 y 2021. Se compararon los pacientes con condición de ingreso directo y aquellos que ingresaron remitidos. Se hicieron análisis de poblaciones de interés como pacientes con trauma severo (ISS > 15) y pacientes con/sin trauma craneoencefálico. Se evaluó el impacto de los pacientes remitidos y su condición al ingreso sobre la mortalidad. Resultados. Se incluyeron 10.814 pacientes. La proporción de pacientes remitidos fue del 54,7 %. Los pacientes que ingresaron remitidos presentaron diferencias respecto a la severidad del trauma y compromiso fisiológico al ingreso comparado con los pacientes con ingreso directo. Los pacientes remitidos tienen mayor riesgo de mortalidad (RR: 2,81; IC95% 2,44-3,22); sin embargo, es el estado fisiológico al ingreso lo que impacta en la mortalidad. Conclusión. Los pacientes remitidos de otras instituciones tienen un mayor riesgo de mortalidad, siendo una inequidad en salud que invita a la articulación de actores institucionales en la atención de trauma. Un centro de trauma debe relacionarse con las instituciones asociadas para crear un sistema de trauma que optimice la atención de los pacientes y la oportunidad

Introduction. This study aims to evaluate the impact on mortality by admission profile to a trauma center in Southwest Colombia between direct and referred patients, as a method to understand the dynamics of trauma care.Methods. A sub-analysis of the Panamerican Trauma Society registry associated with a trauma center in Southwest Colombia was performed. Patients attended between 2012-2021 were analyzed. Patients with direct admission and referred condition were compared. Analyses of populations of interest such as patients with severe trauma (ISS > 15) and patients with/without brain trauma were made. The impact of referred patients and their admission status on mortality was evaluated. Results. A total of 10,814 patients were included. The proportion of referred patients was 54.7%. Patients admitted referred vs. with direct admission have differences regarding trauma severity and physiological compromise on admission. The referred patient has a higher risk of mortality (RR: 2.81; 95% CI 2.44-3.22). There is a high proportion of penetrating trauma by gunshot wounds. However, it is the physiological state at admission that impacts mortality. Conclusion. Patients referred from other institutions have a higher mortality risk, being a health inequity that invites the articulation of institutional actors in trauma care. A trauma center should relate to partner institutions to create a trauma system that optimizes care and timeliness

Basic life support: Awareness, attitude, and knowledge among junior doctors, physiotherapists, and nursing staffs in a tertiary care center of Sikkim

Background: Basic life support (BLS) is a lifesaving skill which every health-care personnel must know. It has been added to the curriculum but still studies have shown poor knowledge and skill among them in India. Aims and Objectives: The aim of our study was to assess attitude and knowledge of BLS among healthcare personnel in a tertiary care center of Sikkim and to recommend training of BLS according to the finding of our study. Materials and Methods: A questionnaire based cross-sectional study was done among junior doctors, physiotherapists, and nursing staffs, who were willing to participate. The questionnaire collected data under the heading of demographics, attitude, awareness, and knowledge about various domains of BLS. Analysis was done with standard statistical software. Results: Among 208 completed surveys, 24 (11.5%) were males and 184 (88.5%) were females, majority of them (76.4%) were nursing staff and belonged to 20�-year age group (76%). Mean score of the participants were 13.43 � 3.725 with a range from 2 to 21. The necessity of BLS training and the requirement of mandatory renewal was strongly agreed by 77.4% and 33.2% participants respectively. Conclusion: We conclude that they all need the trainings at frequent interval to know about the importance of BLS, to gain confidence and to improve their skill which will help them in timely saving of many lives in as well as outside the hospital. This can be achieved if institutes help in conducting the BLS session regularly despite being already in curriculum.

Assessment of Cardiopulmonary Resuscitation Knowledge and Attitude Amongst Interns and Junior Residents of Tertiary Care Centre

Introduction: Cardiopulmonary resuscitation (CPR) is a life saving procedure and adequate knowledge and skills related to CPR are essential for all medical students. This study was undertaken to compare knowledge and practice related to updated CPR guidelines by American Heart Association (AHA) 2020 between junior residents and interns. Methods:This is a questionnaire-based study prepared on Google form consisting of 22 questions on CPR. Total of 124 participants included 41 junior residents and 83 interns. They were advised to read questions carefully and allowed to tick one best response among the options. Results: An average overall correct response from both the group was 14.48 (65.81 %). Among theory knowledge-based questions junior residents had an average of 8.707 correct answers out of 11 (79.15%) which is more correct answers than interns who have average 5.90 correct (53.63%). Similarly, in terms of practical knowledge, junior residents had an average score 9.682 out of 11 (88.026%) compared to interns who had an average of 6.518 out of 11 (59.27%). Conclusion: The study showed poor knowledge about CPR among the interns. More practical based teaching should be employed in MBBS curriculum. Periodical reinforcement and refresher courses should be part of curriculum.

Extracorporeal membrane oxygenation for adult patients with acute poisoning in China: a retrospective analysis of CSECLS registry from 2017 to 2021 / 中华急诊医学杂志

Objective:To analyze the status of extracorporeal membrane oxygenation (ECMO) for poisoned patients in China, and prognosis, complications and risk factors for death in poisoned patients supported with ECMO.Methods:The data of adult poisoned patients registered in Chinese Society of Extracorporeal Life Support (CSECLS) database were collected. Patients were divided into the survival group and death group according to the conditions at discharge. The type of poisoning, patient prognosis, hemodynamic parameters and complications before and after ECMO were retrospectively analyzed.Results:A total of 96 poisoned patients supported with ECMO were included in the database from 2017 to 2022, including 77 adult patients. The use of ECMO for poisoning was more common in Henan Province (28 cases, 36%), Guangdong Province (11 cases, 14%) and Zhejiang Province (9 cases, 8%). The number of adult poisoned patients registered in the database increased over time from 2017 to 2022, but the survival rate showed no significant difference ( P = 0.794). Agricultural poisoning was the most common indication (43%). Veno-arterial (V-A) ECMO was used in 60 patients (78%) and venovenous (V-V) ECMO in 27 patients (22%). Thirty-two patients (42%) survived to hospital discharge. The mean duration of ECMO support was 57 (34, 123) h, the mean duration of mechanical ventilation was 88 (33, 211) h, the mean length of hospital stay was 10 (2, 21) days, and the mean length of ICU stay was 9 (2, 18) days. Multivariate analysis showed that 24-h lactic acid level was significantly associated with mortality ( OR = 0.378, 95% CI: 0.183-0.779, P = 0.008). Conclusions:ECMO can be used as a salvage strategy to treat various types of severe poisoning. Although the application of ECMO is expanded rapidly in China, it is still necessary to optimize intervention indications and treatment timing, and adopt standardized ECMO management and monitoring strategies to improve the prognosis of patients.

Palliative extubation: obstacles, challenges and solutions / Extubación paliativa: obstáculos, desafíos y soluciones

Abstract Life support withdrawal can be a challenging decision, but it should be considered as an option when death is inevitable or recovery to an acceptable quality of life is not possible. The process is beset by obstacles that must be overcome to finally offer patients comfort and a peaceful death. In this article, we offer a series of tools that seek to solve the challenges of palliative extubation, as well as a protocol that could facilitate the decision to withdraw life support, making palliative extubation an alternative to consider instead of artificially prolonging life at the expense of unacceptable human and economic costs.

Resumen La interrupción de la asistencia vital puede ser una decisión complicada, aun cuando se debe considerar como una opción cuando la muerte es inevitable o la recuperación a una calidad de vida aceptable no es posible. A lo largo del proceso se encuentran obstáculos que se deben sortear para finalmente ofrecer a los pacientes una muerte tranquila y confortable. En este artículo ofrecemos una serie de herramientas que buscan solucionar los desafíos de la extubación paliativa y presentamos una guía de extubación que podría facilitar la decisión de retiro del soporte vital, haciendo de la extubación paliativa una alternativa por considerar en lugar de prolongar la vida de manera artificial a expensas de un costo humano y económico inaceptable.

Damage control surgery for splenic trauma: "preserve an organ - preserve a life" / Control de daños en trauma esplénico: "preserva un órgano, preserva la vida"

Abstract The spleen is one of the most commonly injured solid organs of the abdominal cavity and an early diagnosis can reduce the associated mortality. Over the past couple of decades, management of splenic injuries has evolved to a prefered non-operative approach even in severely injured cases. However, the optimal surgical management of splenic trauma in severely injured patients remains controversial. This article aims to present an algorithm for the management of splenic trauma in severely injured patients, that includes basic principles of damage control surgery and is based on the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia. The choice between a conservative or a surgical approach depends on the hemodynamic status of the patient. In hemodynamically stable patients, a computed tomography angiogram should be performed to determine if non-operative management is feasible and if angioembolization is required. While hemodynamically unstable patients should be transferred immediately to the operating room for damage control surgery, which includes splenic packing and placement of a negative pressure dressing, followed by angiography with embolization of any ongoing arterial bleeding. It is our recommendation that both damage control principles and emerging endovascular technologies should be applied to achieve splenic salvage when possible. However, if surgical bleeding persists a splenectomy may be required as a definitive lifesaving maneuver.

Resumen El bazo es uno de los órganos sólidos comprometidos con mayor frecuencia en el trauma abdominal y el diagnóstico oportuno disminuye la mortalidad. El manejo del trauma esplénico ha cambiado considerablemente en las últimas décadas y hoy en día se prefiere un abordaje conservador incluso en casos de lesión severa. Sin embargo, la estrategia óptima para el manejo del trauma esplénico en el paciente severamente traumatizado aún es controvertida. El objetivo de este artículo es proponer una estrategia de manejo para el trauma esplénico en pacientes politraumatizados que incluye los principios de la cirugía de control de daños en base a la experiencia obtenida por el grupo de Cirugía de Trauma y Emergencias (CTE) de Cali, Colombia. La decisión entre un abordaje conservador o quirúrgico depende del estado hemodinámico del paciente. En pacientes hemodinámicamente estables, se debe realizar una tomografía axial computarizada con contraste endovenoso para determinar si es posible un manejo conservador y si requiere angio-embolización. Mientras que los pacientes hemodinámicamente inestables deben ser trasladados inmediatamente al quirófano para empaquetamiento esplénico y colocación de un sistema de presión negativa, seguido de angiografía con embolización de cualquier sangrado arterial persistente. Es nuestra recomendación aplicar conjuntamente los principios del control de daños y las tecnologías endovasculares emergentes para lograr la conservación del bazo, cuando sea posible. Sin embargo, si el sangrado persiste puede requerirse una esplenectomía como medida definitiva para salvaguardar la vida del paciente.

Damage control in penetrating cardiac trauma / El control de daños en el trauma cardíaco penetrante

Abstract Definitive management of hemodynamically stable patients with penetrating cardiac injuries remains controversial between those who propose aggressive invasive care versus those who opt for a less invasive or non-operative approach. This controversy even extends to cases of hemodynamically unstable patients in which damage control surgery is thought to be useful and effective. The aim of this article is to delineate our experience in the surgical management of penetrating cardiac injuries via the creation of a clear and practical algorithm that includes basic principles of damage control surgery. We recommend that all patients with precordial penetrating injuries undergo trans-thoracic ultrasound screening as an integral component of their initial evaluation. In those patients who arrive hemodynamically stable but have a positive ultrasound, a pericardial window with lavage and drainage should follow. We want to emphasize the importance of the pericardial lavage and drainage in the surgical management algorithm of these patients. Before this concept, all positive pericardial windows ended up in an open chest exploration. With the coming of the pericardial lavage and drainage procedure, the reported literature and our experience have shown that 25% of positive pericardial windows do not benefit and/or require further invasive procedures. However, in hemodynamically unstable patients, damage control surgery may still be required to control ongoing bleeding. For this purpose, we propose a surgical management algorithm that includes all of these essential clinical aspects in the care of these patients.

Resumen El manejo definitivo de los pacientes hemodinámicamente estables con heridas cardíacas penetrantes continúa siendo controversial con abordajes invasivos versus manejos conservadores. Estas posiciones contrarias se extienden hasta aquellos casos de pacientes hemodinámicamente inestables donde se ha descrito y considerado la cirugía de control de daños como un procedimiento útil y efectivo. El objetivo de este artículo es presentar la experiencia en el manejo quirúrgico de heridas cardíacas penetrantes con la creación de un algoritmo práctico que incluye los principios básicos del control de daños. Se recomienda que a todos los pacientes con heridas precordiales penetrantes se les debe realizar un ultrasonido torácico como componente integral de la evaluación inicial. Aquellos que presenten un ultrasonido torácico positivo y se encuentren hemodinámicamente estables se les debe realizar una ventana pericárdica con posterior lavado. Se ha demostrado que el 25% de las ventanas pericárdicas positivas no se benefician ni requieren de posteriores abordajes quirúrgicos invasivos. Antes de este concepto, todos los pacientes con ventana pericárdica positiva terminaban en una exploración abierta del tórax y del pericárdico. Los pacientes hemodinámicamente inestables requieren de una cirugía de control de daños para un adecuado y oportuno control del sangrado. Con este propósito, se propone un algoritmo de manejo quirúrgico que incluye todos estos aspectos esenciales en el abordaje de este grupo de pacientes.

Damage control of peripheral vascular trauma - Don't be afraid of axillary or popliteal fosses / Control de daños del trauma vascular periférico - No le tema a la fosa axilar o poplítea

Abstract Peripheral vascular injuries are uncommon in civilian trauma but can threaten the patient's life or the viability of the limb. The definitive control of the vascular injury represents a surgical challenge, especially if the patient is hemodynamically unstable. This article proposes the management of peripheral vascular trauma following damage control surgery principles. It is essential to rapidly identify vascular injury signs and perform temporary bleeding control maneuvers. The surgical approaches according to the anatomical injured region should be selected. We propose two novel approaches to access the axillary and popliteal zones. The priority should be to reestablish limb perfusion via primary repair or damage control techniques (vascular shunt or endovascular approach). Major vascular surgeries should be managed post-operatively in the intensive care unit, which will allow correction of physiological derangement and identification of those developing compartmental syndrome. All permanent or temporary vascular procedures should be followed by a definitive repair within the first 8 hours. An early diagnosis and opportune intervention are fundamental to preserve the function and perfusion of the extremity.

Resumen El trauma vascular periférico no es común en el contexto civil, pero representa una amenaza para la vida del paciente o de la extremidad. El control definitivo de la lesión vascular representa un desafío quirúrgico, especialmente en pacientes con inestabilidad hemodinámica. Este artículo describe la propuesta de manejo del trauma vascular periférico de acuerdo con los principios de la cirugía de control de daños. Se debe identificar los signos sugestivos de lesión vascular y realizar oportunamente maniobras temporales para el control del sangrado. Se debe elegir el abordaje quirúrgico dependiendo del área anatómica lesionada. Se proponen dos nuevas incisiones para acceder a la región axilar y poplítea. La prioridad es restablecer la perfusión de la extremidad mediante el reparo primario o técnicas de control de daños (shunt vascular o abordaje endovascular). Los pacientes sometidos a cirugías vasculares mayores deben ser manejados postoperatoriamente en la unidad de cuidados intensivos para corregir las alteraciones fisiológicas e identificar aquellos que desarrollen un síndrome compartimental. Todos los procedimientos vasculares permanentes o temporales deben contar con un reparo definitivo en las primeras 8 horas. El diagnóstico temprano e intervención oportuna son fundamentales para salvaguardar la perfusión y funcionalidad de la extremidad.

Damage control in penetrating carotid artery trauma: changing a 100-year paradigm / Control de daños en el trauma penetrante de la arteria carótida: cambiando un paradigma de 100 años

Abstract Carotid artery trauma carries a high risk of neurological sequelae and death. Surgical management of these injuries has been controversial because it entails deciding between repair or ligation of the vessel, for which there is still no true consensus either way. This article proposes a new management strategy for carotid artery injuries based on the principles of damage control surgery which include endovascular and/or traditional open repair techniques. The decision to operate immediately or to perform further imaging studies will depend on the patient's hemodynamic status. If the patient presents with massive bleeding, an expanding neck hematoma or refractory hypovolemic shock, urgent surgical intervention is indicated. An altered mental status upon arrival is a potentially poor prognosis marker and should be taken into account in the therapeutic decision-making. We describe a step-by-step algorithmic approach to these injuries, including open and endovascular techniques. In addition, conservative non-operative management has also been included as a potentially viable strategy in selected patients, which avoids unnecessary surgery in many cases.

Resumen El trauma de la arteria carótida tiene una alta probabilidad de muerte y de secuelas neurológicas. El manejo quirúrgico es objeto de controversia porque se tiene que decidir entre reparar la arteria carótida o ligarla, para lo cual aún no existe un consenso. El objetivo de este artículo es proponer una nueva estrategia de manejo para el trauma de la arteria carótida con los principios de la cirugía de control de daños y el uso de técnicas como el reparo endovascular o el manejo conservador. La decisión de operar el paciente inmediatamente o realizar estudios imagenológicos dependerá del estado hemodinámico del paciente. Si el paciente presenta sangrado masivo, hematoma expansivo o choque hipovolémico refractario, una intervención quirúrgica urgente esta indicada. Un déficit del estado neurológico al ingreso es un marcador de mal pronóstico en estos casos e influye en la toma de decisiones. Se describe el paso a paso del reparo vascular abierto y se incluye las estrategias de manejo tanto endovasculares como abiertas. Adicionalmente, el manejo conservador también ha sido incluido como una estrategia viable en pacientes seleccionados, evitando cirugías innecesarias.

Primary repair: damage control surgery in esophageal trauma / El reparo primario: el control de daños en el trauma de esófago

Abstract Esophageal trauma is a rare but life-threatening event associated with high morbidity and mortality. An inadvertent esophageal perforation can rapidly contaminate the neck, mediastinum, pleural space, or abdominal cavity, resulting in sepsis or septic shock. Higher complications and mortality rates are commonly associated with adjacent organ injuries and/or delays in diagnosis or definitive management. This article aims to delineate the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia, on the surgical management of esophageal trauma following damage control principles. Esophageal injuries should always be suspected in thoracoabdominal or cervical trauma when the trajectory or mechanism suggests so. Hemodynamically stable patients should be radiologically evaluated before a surgical correction, ideally with computed tomography of the neck, chest, and abdomen. While hemodynamically unstable patients should be immediately transferred to the operating room for direct surgical control. A primary repair is the surgical management of choice in all esophageal injuries, along with endoscopic nasogastric tube placement and immediate postoperative care in the intensive care unit. We propose an easy-to-follow surgical management algorithm that sticks to the philosophy of "Less is Better" by avoiding esophagostomas.

Resumen El trauma esofágico es un evento poco frecuente pero potencialmente mortal. Una perforación esofágica inadvertida puede ocasionar la rápida contaminación del cuello, el mediastino, el espacio pleural o la cavidad abdominal, lo cual puede resultar en sepsis o choque séptico. Las complicaciones y la mortalidad aumentan con el retraso en el diagnóstico o manejo definitivo, y la presencia de lesiones asociadas. El objetivo del presente artículo es describir la experiencia adquirida por el grupo de cirugía de Trauma y Emergencias (CTE) de Cali, Colombia en el manejo del trauma de esófago de acuerdo con los principios de la cirugía de control de daños. Las lesiones esofágicas deben sospecharse en todo trauma toraco-abdominal o cervical en el que el mecanismo o la trayectoria de la lesión lo sugieran. El paciente hemodinámicamente estable se debe estudiar con imágenes diagnósticas antes de la corrección quirúrgica del defecto, idealmente por medio de tomografía computarizada del cuello, tórax y abdomen con contraste endovenoso. Mientras que en el paciente hemodinámicamente inestable se debe explorar y controlar la lesión. El reparo primario es el manejo quirúrgico de elección, con la previa colocación de una sonda nasogástrica y el seguimiento postoperatorio estricto en la unidad de cuidado intensivo. Se propone un algoritmo de manejo quirúrgico que resulta fácil de seguir y adopta la premisa "Menos es Mejor" evitando realizar derivaciones esofágicas.

Eficacia de los agentes hemostáticos para el control de hemorragias externas en sanidad militar / Effectiveness of hemostatic agents to control external bleeding in military health

Introducción: Es creciente el uso de nuevos agentes hemostáticos para controlar la hemorragia en entornos militares. Objetivos: Sintetizar y analizar la evidencia disponible sobre la eficacia de diferentes agentes hemostáticos utilizados en ambientes tácticos, transportados por los combatientes del ejército. Desarrollo: Se realizó una revisión narrativa de artículos publicados en inglés y español, en las bases de datos Medline (PubMed), Cochrane, Web of Science y en revistas, protocolos, libros y manuales del ámbito de urgencias y emergencias en el campo de batalla, que analizaron el fenómeno de estudio y cumplieron los criterios de inclusión y exclusión. Tras la búsqueda y selección de los estudios, 7 artículos fueron incluidos en la síntesis narrativa. En los estudios se utilizaron los siguientes agentes hemostáticos QuikClot®, HemCon®, Celox® y el ChitoGauze HemCon®; en la mayoría de los estudios, los agentes hemostáticos tuvieron una eficacia superior al 88 por ciento para detener, disminuir y controlar la hemorragia externa en víctimas de combate, sobre todo en zonas de unión (articulaciones) y para reducir la morbilidad y mortalidad. Solo QuikClot® tuvo efectos secundarios negativos, al provocar quemaduras. El correcto manejo de los agentes hemostáticos requiere de formación previa, lo que evita errores de administración. Conclusiones: Los agentes hemostáticos son eficaces para el abordaje de la hemorragia externa y aumentan la supervivencia en víctimas de combate. Es necesario formar a los profesionales para evitar errores en su manejo. Futuros estudios deben indagar cuál de estos agentes es más eficaz(AU)

Development: A narrative review of articles published in English and Spanish, in Medline (PubMed), Cochrane and Web of Science, and magazines, protocols, books, and manuals in the field of emergency and battlefield emergencies, who analyzed the study phenomenon and met the inclusion and exclusion criteria. After searching and selecting the studies, 7 articles were included in the narrative synthesis. In the studies, the following hemostatic agents were used QuikClot®, HemCon®, Celox®, and ChitoGauze HemCon®, in most studies, hemostatic agents were more than 88 percent effective in stopping, reducing, and controlling external hemorrhage in combat victims, especially in union areas, also decreasing morbidity and mortality. Only QuikClot® had negative side effects causing burns. The correct handling of hemostatic agents requires prior training, which avoids administration mistakes. Conclusions: Hemostatic agents are effective for treating external hemorrhage in combat victims and increasing their survival. It is necessary to train professionals to avoid mistakes in their handling. Future studies should investigate which of these agents is more effective(AU)

Manejo agudo de la intoxicación medicamentosa / Acute management of drug intoxication

Resumen Las intoxicaciones o las sobredosis de drogas constituyen una fuente importante de morbilidad, mortalidad y gasto en salud en todo el mundo. Especialmente en adultos menores de 35 años, las intoxicaciones vienen a ser la principal causa de paro cardíaco no traumático, siendofármacos más comunes involucrados, analgésicos, antidepresivos, opioides, sin embargo, esto puede variar. Es importante realizar un abordaje rápido, con base en interrogatorio, información de cualquier testigo y evidencia, además la clínica del paciente. El paro cardíaco debido a toxicidad se maneja de acuerdo conlos estándares actuales de reanimación cardiopulmonar básica y avanzada, siguiendo los principios del A, B, C, D, E. Las manifestaciones clínicas y abordaje clínico pueden variar bastante dependiendo de la sustancia involucrada. Las pruebas de laboratorio casi nunca están disponibles en un marco de tiempo que respalde las decisiones de reanimación tempranas, aún así, es recomendable realizarlas. En general los efectos tóxicos pueden reducirse si se limita la absorción del o los fármacos o se aumenta su eliminación. Además, se puede bloquear efectos farmacológicos no deseados con los llamados antídotos. El uso del carbón activado, algunos antídotos específicos, y tratamientos extracorpóreos también se contemplan en la presente revisión.

Abstract Poisoning or drug overdose is a major source of morbidity, mortality and health expenditure worldwide, especially in adults under 35, where it is the leading cause of non-traumatic cardiac arrest, being more common drugs involved, analgesics, antidepressants, opioids, however, this may vary. It is important to make a quick approach, based on questioning, information from any witness and evidence, and the patient's clinic. Cardiac arrest due to toxicity is managed according to current Basic and Advanced life support standards, following the principles of A, B, C, D, E. Clinical manifestations and clinical approach can vary considerably depending on the substance involved. Laboratory tests are almost never available in a time frame that supports early resuscitation decisions, yet it is advisable to perform them. In general, the toxic effects can be reduced if the absorption of the drugs is limited or their elimination increased. In addition, you can block unwanted pharmacological effects with so-called antidotes. The use of activated charcoal, specific antidotes, and extracorporeal treatments are also covered in this review.
