FAST is essential to decide whether trauma patients need laparotomy, but it has a notable decrease in accuracy in patients with pelvic fracture. Our objective is to analyze the consequences of therapeutic decision-making based on the FAST results in trauma patients with pelvic fracture.Descriptive study that includes trauma patients older than 16 with a pelvic fracture admitted to the critical care area or who died. The FAST result was compared with a true positive or negative value according to the results of laparotomy or abdominal CT. We recorded diagnosis and treatment of each injury and resolution of the case, detailing the cause of death, among all variables.Over the 13-year period, we included 263 trauma patients with pelvic fracture, with a mean ISS of 31 and mortality of 19%. FAST had a sensitivity of 65.2%, specificity of 69%, false negative rate of 34.8% and false positive rate of 30.9%. Hemodynamically unstable patients died twice as many stable patients (27% vs 14%, P .05). Patients with positive FAST died more than negative FAST (43% vs 26%); and 4 out of 10 hemodynamically unstable patients who underwent non-therapeutic laparotomy after presenting a false positive FAST died from hypovolemic shock. The mortality rate fell from 60% to 20% when preperitoneal packing was performed before angio-embolization of the pelvis.FAST has low accuracy in polytraumatized patients with pelvic fracture. Patients with false positive FAST have higher mortality, which can be reduced notably by applying preperitoneal packing.

El objetivo es analizar las consecuencias de tomar decisiones terapeuticas basadas en el resultado del FAST en los pacientes politraumaticos con fractura de pelvis. Metodos Estudio descriptivo de pacientes con politraumatismos mayores de 16 anos que han ingresado en el area de criticos o que han fallecido previamente, con fractura pelvica. El resultado del FAST ha sido comparado con un valor realmente positivo o negativo segun el resultado de la laparotomia o de la tomografia computarizada. Resultados En 13 anos, se ha incluido a 263 pacientes politraumaticos con fractura pelvica (ISS medio de 31; mortalidad 19%). El FAST tenia una sensibilidad del 65,2%, una especificidad del 69%, una tasa de falsos negativos del 34,8% y una tasa de falsos positivos del 30,9%. Los pacientes hemodinamicamente inestables tenian el doble de mortalidad que los pacientes estables (27% vs. 14%, p Conclusiones La reducida eficacia del FAST en pacientes con fractura de pelvis nos obliga a cuestionarnos las consecuencias de la toma de decisiones terapeuticas con base en sus resultados. Los pacientes con FAST falsamente positivo tienen una mortalidad mayor, que se puede reducir aplicando un packing preperitoneal.

Resumen Introduccion Las constantes vitales detectan la presencia de hemorragia al perder grandes cantidades de sangre, lo que comporta una gran morbimortalidad. El Shock Index (SI) es un parametro que detecta el sangrado con puntos de corte de 0,9. El objetivo de este estudio es valorar si un punto de corte de ≥ 0,8 es mas sensible para detectar sangrado oculto, permitiendo iniciar maniobras terapeuticas mas precoces. Metodos Estudio analitico de validacion del SI que incluye pacientes politraumatizados graves mayores de 16 anos. Se registran constantes vitales y escalas predictivas de sangrado: SI, Assessment of Blood Consumption score y Pulse Rate Over Pressure score. Se analiza la relacion del SI con 5 marcadores predictivos de sangrado: necesidad de transfusion masiva, embolizacion angiografica, control del sangrado quirurgico, muerte por shock hipovolemico y «sangrado activo» (presencia de al menos uno de los 4 marcadores anteriores en un paciente). Resultados Recogida prospectiva de datos de 1.402 pacientes politraumatizados durante 10 anos. El Injury Severity Score medio fue de 20,9 (DE 15,8). Hubo una mortalidad del 10%. El SI medio fue de 0,73 (DE 0,29). En total presentaron «sangrado activo» el 18,7% de la serie. El SI medio en los pacientes con «sangrado activo» fue de 0,87, mientras que las constantes vitales estaban dentro de la normalidad. El area bajo la curva ROC del SI para el «sangrado activo» fue de 0,749. Conclusiones El SI con un punto de corte ≥ 0,8 es mas sensible que aquel con el punto de corte ≥ 0,9 y permite iniciar maniobras de reanimacion mas precoces en los pacientes con sangrado oculto.

Introduction Vital signs indicate the presence of bleeding only after large amounts of blood have been lost, with high morbidity and mortality. The Shock Index (SI) is a hemorrhage indicator with a cut-off point for the risk of bleeding at 0.9. The aim of this study is to assess whether a cut-off of ≥0.8 is more sensitive for detecting occult bleeding, providing for early initiation of therapeutic maneuvers. Methods SI analytical validation study of severe trauma patients older than 16 years of age. Vital signs were recorded, and scales for predicting bleeding included: SI, Assessment of Blood Consumption score, and Pulse Rate Over Pressure score. The relationship between the SI and 5 markers for bleeding was analyzed: need for massive transfusion, angiographic embolization, surgical bleeding control, death due to hypovolemic shock, and the overall predictor “active bleeding” (defined as the presence of at least one of the 4 markers above). Results Data from 1402 trauma patients were collected prospectively over a period of 10 years. The mean Injury Severity Score was 20.9 (SD 15.8). The mortality rate was 10%. The mean SI was 0.73 (SD 0.29). “Active bleeding” was present in 18.7% of patients. The SI area under the ROC curve for “active bleeding” was 0.749. Conclusions An SI cut-off point ≥0.8 is more sensitive than ≥0.9 and allows for earlier initiation of resuscitation maneuvers in patients with occult active bleeding.

An important drawback of local surgery for lesions in the anal canal is the difficulty of achieving en bloc full-thickness resections. The aim of this study is to evaluate TEM/TEO in lesions of this type from the point of view of morbidity, mortality and the quality of the pathology specimen. This is an observational study with prospective data collection from June 2004 to July 2018. Two groups are defined: group A (rectal tumors with proximal margin between 0 and ≤4 cm from anal verge) and group B (distal margin > 4 cm from anal verge). A technical description is provided; resections and postoperative complications in both groups are compared. During the study period, 757 patients underwent TEM/TEO. Finally, 692 patients were included, 192 patients in group A and 500 patients in group B. An en bloc surgical specimen was obtained in 176/192 patients (91.7%), although the defect was completely sutured in 132 (68.8%). In the comparative analysis, group A did not present significantly greater fragmentation of the resected piece [16/192 (8.3%) vs. 36/500 (7.2%), p = 0.630], although group A was associated with greater involvement of the surgical margin [28/192 (14.6%), 32/500 (6.4%), p = 0.001] and clinically relevant morbidity [16/192 (8.3%), 20/500 (4%), p = 0.034]. There was no mortality. The use of TEM/TEO to remove lesions originating in the anal canal is feasible. But we have to take into account that there is an increase in complications, technical difficulties and affected margins resection.

Resumen Introduccion El politraumatismo sigue siendo una de las principales causas de muerte entre los 10 y los 40 anos, causando graves incapacidades en los pacientes que sobreviven. El objetivo de nuestro estudio es realizar un analisis de calidad de la atencion del paciente politraumatizado mediante un estudio epidemiologico. Metodo Registro prospectivo de todos los pacientes politraumaticos atendidos en nuestro hospital, mayores de 16 anos, que ingresan en el area de criticos o mueren antes del ingreso. Resultados Desde marzo del 2006 hasta agosto del 2014, registramos 1.200 politraumatizados. La mayoria fueron hombres (75%), con una mediana de edad de 45 anos. El ISS medio fue de 20,9 ± 15,8 y el mecanismo de accion mas frecuente fue cerrado (94% casos). La mortalidad global fue del 9,8% (117 casos), siendo la muerte neurologica la principal causa de fallecimiento (45,3%), seguida de la muerte por shock hipovolemico (29,1%). En 17 casos (14,5% fallecimiento) la mortalidad fue considerada como evitable o potencialmente evitable un total de 327 pacientes (27,3%) precisaron de tratamiento quirurgico urgente y 106 pacientes (8,8%) precisaron de un tratamiento mediante radiologia intervencionista de caracter urgente. El 18,5% de los pacientes (222) presentaron alguna lesion inadvertida, con un total de 318 lesiones inadvertidas. Conclusion La atencion ofrecida en nuestro centro es correcta. La necesidad de una recogida de datos prospectiva de la atencion global a los pacientes politraumatizados es necesaria e imprescindible para poder evaluar la calidad ofrecida y mejorar los resultados.
