ABSTRACT

Introducción. El trauma es una de las entidades con mayor morbimortalidad en el mundo. Los equipos especializados en la atención del paciente traumatizado son llamados «equipos de trauma¼. Dichos equipos surgieron de la necesidad de brindar tratamiento oportuno multidisciplinario a individuos con heridas que condicionan gran severidad en la guerra; sin embargo, con el paso del tiempo se trasladaron al ámbito civil, generando un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad. El objetivo de este estudio fue describir el proceso de desarrollo de los equipos de trauma a nivel mundial y la experiencia en nuestra institución en el suroccidente colombiano. Métodos. Se realizó una búsqueda en la base de datos PUBMED, que incluyó revisiones sistemáticas, metaanálisis, revisiones de Cochrane, ensayos clínicos y series de casos. Resultados. Se incluyeron 41 estudios para esta revisión narrativa, y se observó que el tiempo de permanencia en Emergencias, el tiempo de traslado a cirugía, la mortalidad y las complicaciones asociadas al trauma fueron menores cuando se implementan equipos de trauma. Discusión. El diseño de un sistema de atención y valoración horizontal de un paciente con traumatismos severos produce un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad. Se hace necesario establecer los parámetros operativos necesarios en las instituciones de salud de alta y mediana complejidad en nuestro país para implementar dichos equipos de trabajo


Introduction. Trauma is one of the entities with the highest morbidity and mortality in the world. Teams specialized in trauma patient care are called «trauma teams¼. These teams arose from the need to provide timely multidisciplinary treatment to individuals with severe injuries in war; however, with time they moved to the civilian arena, generating a positive impact in terms of care times, mortality and morbidity. The objective of this study was to describe the process of development of trauma teams worldwide and the experience in our institution in southwestern Colombia. Methods. A search of the PUBMED database was carried out, which included systematic reviews, metaanalyses, Cochrane reviews, clinical trials, and case series.Results. Forty-one studies were included for this narrative review, and it was observed that the length of stay in the ER, the time of transfer to surgery, mortality and complications associated with trauma were lower when trauma teams are implemented. Discussion. The design of a horizontal care and assessment system for a patient with severe trauma produces a positive impact in terms of care times, mortality and morbidity. It is necessary to establish operational parameters in high and medium complexity health institutions in our country to implement such work teams

ABSTRACT

RESUMO Considera-se que a transfusão de eritrócitos melhora a respiração celular durante o choque séptico. Contudo, seu impacto agudo no transporte e no metabolismo de oxigênio nessa condição ainda é amplamente debatido. O objetivo deste estudo foi avaliar o impacto da transfusão de eritrócitos na microcirculação e no metabolismo do oxigênio em pacientes com sepse e choque séptico. Conduzimos um levantamento nas bases de dados MEDLINE®, Elsevier e Scopus. Incluímos estudos realizados com seres humanos adultos com sepse e choque séptico. Realizamos uma revisão sistemática e metanálise com utilização do modelo de efeitos aleatórios de DerSimonian e Laird. Consideramos significante valor de p < 0,05. Incluíram-se na análise 19 manuscritos, correspondentes a 428 pacientes. As transfusões de eritrócitos se associaram com aumento de 3,7% na média combinada de saturação venosa mista de oxigênio (p < 0,001), diminuição de razão de extração de oxigênio de -6,98 (p < 0,001) e nenhum efeito significante no índice cardíaco (0,02 L/minuto; p = 0,96). Obtiveram-se resultados similares em estudos que incluíram mensurações simultâneas de saturação venosa mista de oxigênio, razão de extração de oxigênio e índice cardíaco. As transfusões de eritrócitos levaram a aumento significante na proporção de pequenos vasos perfundidos (2,85%; p = 0,553), enquanto os parâmetros de oxigenação tissular revelaram aumento significante no índice de hemoglobina tissular (1,66; p = 0,018). Estudos individuais relataram melhoras significantes na oxigenação tissular e nos parâmetros microcirculatórios sublinguais em pacientes com microcirculação alterada na avaliação inicial. A transfusão de eritrócitos pareceu melhorar o metabolismo sistêmico de oxigênio com aparente independência de variações no débito cardíaco. Observaram-se alguns efeitos benéficos para a oxigenação tissular e parâmetros microcirculatórios, em particular em pacientes com alterações iniciais mais graves. São necessários mais estudos para avaliar seu impacto clínico e individualizar as decisões relativas à transfusão.


ABSTRACT Red blood cell transfusion is thought to improve cell respiration during septic shock. Nevertheless, its acute impact on oxygen transport and metabolism in this condition remains highly debatable. The objective of this study was to evaluate the impact of red blood cell transfusion on microcirculation and oxygen metabolism in patients with sepsis and septic shock. We conducted a search in the MEDLINE®, Elsevier and Scopus databases. We included studies conducted in adult humans with sepsis and septic shock. A systematic review and meta-analysis were performed using the DerSimonian and Laird random-effects model. A p value < 0.05 was considered significant. Nineteen manuscripts with 428 patients were included in the analysis. Red blood cell transfusions were associated with an increase in the pooled mean venous oxygen saturation of 3.7% (p < 0.001), a decrease in oxygen extraction ratio of -6.98 (p < 0.001) and had no significant effect on the cardiac index (0.02L/minute; p = 0,96). Similar results were obtained in studies including simultaneous measurements of venous oxygen saturation, oxygen extraction ratio, and cardiac index. Red blood cell transfusions led to a significant increase in the proportion of perfused small vessels (2.85%; p = 0.553), while tissue oxygenation parameters revealed a significant increase in the tissue hemoglobin index (1.66; p = 0.018). Individual studies reported significant improvements in tissue oxygenation and sublingual microcirculatory parameters in patients with deranged microcirculation at baseline. Red blood cell transfusions seemed to improve systemic oxygen metabolism with apparent independence from cardiac index variations. Some beneficial effects have been observed for tissue oxygenation and microcirculation parameters, particularly in patients with more severe alterations at baseline. More studies are necessary to evaluate their clinical impact and to individualize transfusion decisions.

ABSTRACT

La infección por Clostridium difficile es la principal causa de diarrea asociada al cuidado de la salud. Durante los últimos años se ha incrementado la morbilidad y mortalidad por esta infección. Las recientes investigaciones se orientan a la búsqueda de tratamientos alternativos a la colectomía subtotal para los pacientes con infecciones severas por Clostridium difficile, es por esto que el presente artículo tiene como objetivo hacer la revisión del caso clínico de una paciente con colitis severa por Clostridium difficile refractaria al manejo de primera línea, que respondió satisfactoriamente al tratamiento con lavado colónico anterógrado con vancomicina vía ileostomía en asa.


Clostridium difficile infection is the main cause of diarrhea in health care settings. Such infections have led to an increase in morbidity and mortality in recent years. Alternative treatments to subtotal colectomy have been sought for patients with severe infections caused by Clostridium difficile. The objective of this article is to present a clinical case report of a patient with severe colitis caused by Clostridium difficile that was refractory to first-line management, which responded satisfac torily to treatment with anterograde colonic lavages with vancomycin via loop ileostomy.

ABSTRACT

Introducción. La maniobra de reanimación mediante el denominado "balón de reanimación endovascular de aorta"(Resuscitative Endovascular Balloon Occlusion of the Aorta, REBOA), es un procedimiento para obtener el control proximal de la hemorragia. Nuestra hipótesis es que puede usarse como una maniobra emergente para el manejo del choque hemorrágico y como una intervención para prevenir la aparición de hemorragia masiva en los pacientes en riesgo. Materiales y métodos. Se recolectaron los datos de una cohorte prospectiva de pacientes entre el 2014 y 2018 en un centro de trauma de nivel I del suroccidente colombiano. Los datos se presentaron, de acuerdo con su distribución de normalidad, en medias y desviaciones estándar o medianas y rangos intercuartílicos. Resultados. Se incluyeron 70 pacientes, 27 considerados en riesgo de choque hemorrágico (mujeres embarazadas con placentación anormal) y 43 con choque hemorrágico (pacientes de trauma sometidos a cirugía y oclusión aórtica con balón). En el primer grupo, ningún paciente requirió transfusión masiva y no se reportaron muertes. En el último, hubo aumento significativo de la presión arterial sistémica después del procedimiento de 50,1 ± 22,5 a 107 mm Hg (rango: 87-129) y la mortalidad fue del 30,2 %. Conclusión. Esta muestra de pacientes sometidos a reanimación mediante oclusión aórtica con REBOA es la más grande reportada hasta ahora en Latinoamérica. Esta es una herramienta eficaz para el manejo de pacientes en choque hemorrágico o en riesgo de uno


Introduction: Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a procedure that involves placement of an endovascular balloon in the aorta to obtain proximal control of hemorrhage. We hypothesize that the REBOA can be used as an emergent maneuver for the management of patients with hemorrhagic shock and as a prophylactic intervention to prevent the appearance of massive hemorrhage in populations at risk. Methods: Data were collected from a prospective cohort of patients in the period between 2014 and 2018, at a level I trauma center in Southwestern Colombia. The data was presented according to their distribution of normality, in means and standard deviations or medians and interquartile ranges. Results: Seventy patients were included, 27 considered at risk of hemorrhagic shock (pregnant women with abnormal placentation) and 43 with hemorrhagic shock (trauma patients undergoing surgery and REBOA). In the first group, no patient required massive transfusion and no deaths were reported. In the latter, there was a significant increase in blood pressure [SBP pre-REBOA: 50.1 ± 22.5, post-REBOA SBP: 107 (87-129)] and mortality was 30.2%. Conclusion: Our experience in the use of REBOA is the largest reported in Latin America. This is an effective tool for the management of patients at or at risk of hemorrhagic shock

ABSTRACT

Introducción. La hemorragia no controlada es la principal causa prevenible de muerte en trauma. No hay precedentes locales que estimen el efecto de estrategias de prevención que involucren al público en la atención inicial de las víctimas. Objetivo. Evaluar si es factible implementar programas de entrenamiento para el control prehospitalario básico del sangrado en pacientes de trauma, en un país de bajos a medianos ingresos. Métodos. Cirujanos y estudiantes de medicina se encargaron de desplegar el curso "Stop the bleed" en estudiantes universitarios del suroccidente colombiano. Se hizo una evaluación antes y después de hacer el entrenamiento. Se usó la prueba t de Student y un análisis de regresión logística ordinal, para determinar los factores que estuvieron asociados a obtener mejores puntajes en la evaluación del curso. Resultados. Se entrenaron 265 estudiantes, con una edad media de 21,4 ± 4 años, de los cuales 136 (51,5 %) eran mujeres. Después de recibir el entrenamiento un participante tuvo 15,6 veces la oportunidad de obtener mayor puntaje de calificación con respecto al periodo preentrenamiento [IC95%: 15,1-16,2 (p<0,001)], 99,4 y 95,2 %, respectivamente, estarían dispuestos a tomar medidas y colocar un torniquete a una víctima de sangrado (p<0,001). Conclusión. Es factible para los países con recursos limitados hacer el entrenamiento en control básico del sangrado. Este se puede llevar a cabo de manera eficaz, tanto por instructores con un bagaje amplio en técnicas de control del sangrado como por instructores con menor nivel de formación, pero con un entrenamiento adecuado


Background: uncontrolled hemorrhage is the leading cause of preventable death in trauma. There are no local precedents that estimate the effect of prevention strategies that involve the public in the initial care of victims. Our objective was to evaluate if it is feasible to implement training programs for the basic control of prehospital bleeding in trauma patients, in a low to a middle-income country. Methods: Surgeons and medical students deploying the Stop the bleed course in a Colombian southwestern university, evaluation was performed before and after the training. A T-test and an ordinal logistic regression analysis were used to determine the factors associated with better scores in the course evaluation. Results: of the 265 students, were women 136 (51.5%), age was 21.4± 4. After receiving the training, a participant had 15.6 times the chance of obtaining a higher score than the pre-training period [95% CI: 15.1-16.2 (p <0.001)]. 99.4% and 95.2% respectively, would be willing to take actions and place a tourniquet on a bleeding victim (p <0.001). Conclusion: in a low to a middle-income country is feasible to perform the Bleeding Control Basic training. This can be done effectively by instructors with a broad background in bleeding control techniques as well as by instructors with less experience, but with adequate training

ABSTRACT

Abstract Introduction: To achieve minimal physiological goals in patients with penetrating thoracoabdominal trauma (TAPT) is essential to ensure adequate outcomes. Objectives: To determine the success in meting basic standards at the end of damage control surgery in subjects with TAPT: (1) Monitoring and prevention of hyperfibrinolysis; (2) central temperature >35 °C; (3) platelet count >50,000/mm³ and serum fibrinogen >150mg/dl; (4) hemoglobin levels >7.5 mg/dl and base deficit <6. Methods: Subjects >18 years old undergoing damage control surgery as a result of TAPT were prospectively collected at a referral center between October Oct-2012 and Dec-2014. Comparisons were done according to the Injury Severity Score (ISS) with a severity value indicator of >25. A p < 0.05 value was considered significant. Results:106 subjects with TAPT were enrolled. Administration of tranexamic acid was only reported in 52.7% of the patients, particularly in the group with low severity scores [Group ISS < 25 36.3% vs. group ISS > 25 65.8%. OR 3.37 (95% CI 1.2-9.85); p = 0.01]. Although the temperature was reported in 91% of the cases, only 66.2-71.4% reached the recommended goal. Serum fibrinogen was measured in 59.5% of the cases and only 52% met the recommended level. The base deficit values of <6 at the end of surgery were only accomplished in 40-43.8% of the subjects, with a significantly lower probability in the more severe patients [53% vs. 35.9%. OR 2.04 (95% CI 1.2-6.02); p = 0.042]. Conclusions: A considerable proportion of patients with TAPT does not meet the current recommendations at the end of damage control surgery.


Introducción: El logro de metas fisiológicas mínimas en pacientes con trauma toracoabdominal penetrante (TTAP) es fundamental para garantizar adecuados desenlaces. Objetivos: Determinar el éxito en el logro de estándares básicos al final de la cirugía de control de daños en sujetos con TTAP: 1.Monitorización y prevención de hiperfibrinolisis; 2.Temperatura central > 35 °C; 3.Niveles plaquetarios>50.000/mm3 y de fibrinógeno sérico > 150 mg/dl; 4.Niveles de hemoglobina > 7.5 mg/dl y déficit de base < 6. Métodos: Se recolectaron prospectivamente sujetos > 18 años llevados a cirugía de control de daños por TTAP en un centro de remisión entre Oct-2012 y Dic-2014. Las comparaciones se realizaron según el Injury severity score (ISS) teniendo como indicador de severidad un valor >25. Se consideró significativo un valor de p < 0.05. Resultados: Se registraron 106 sujetos con TTAP. La aplicación de ácido tranexámico solo se reportó en 52.7% de los pacientes, especialmente en el grupo con puntajes de severidad bajos [Grupo ISS<25 36.3% vs. grupo ISS > 25 65.8%. OR 3.37 (IC95% 1.2-9.85); p = 0.01]. A pesar de que la temperatura fue reportada en 91% de los casos, solo 66.2-71.4% alcanzaron la meta recomendada. El fibrinógeno sérico fue valorado en 59.5% de los sujetos y solo 52% alcanzaron la recomendación. Valores de déficit de base < 6 Al final de cirugía solo se lograron en 40-43.8% de los sujetos, con una probabilidad significativamente menor en los sujetos más graves [53% vs. 35.9%. OR 2.04 (IC95% 1.2-6.02); p = 0.042]. Conclusiones: Una proporción considerable de pacientes con TTAP no logran las recomendaciones actuales al final de la cirugía de control de daños.
