[Translated article] Spinopelvic dissociation: Current concepts.

INTRODUCTION: Spinopelvic dissociation is an uncommon injury, but, at the same time, very serious, since it can associate important complications with high morbidity and mortality. Its low frequency means that the experience of the specialists who have to deal with it is often very limited. OBJECTIVE: To analyze the treatment indications based in classifications and surgery techniques. METHOD: A search for scientific articles from high-impact journals was performed through international databases, such as Pubmed, Cochrane Library, Scopus, Science Direct and OVID. CONCLUSIONS: The management of the injury we are analyzing represents a challenge. The diagnosis is carried out through a meticulous anamnesis and physical examination, supported by imaging tests, where tomography acquires special relevance. The treatment is fundamentally surgical, reserved the conservative option for a few cases. Triangular fixation is nowadays considered the treatment of choice.

Utilización de los estudios tomográficos en pacientes politraumatizados

Introducción: El trauma implica una forma integral de manejo que requiere una significativa inversión en dos aspectos: económico y educativo. Los pacientes politraumatizados son difíciles de valorar, diagnosticar y tratar, ya que presentan un riesgo vital elevado, por lo que se requiere un diagnóstico y tratamiento rápido, complejo y multidisciplinario. Objetivo: Determinar cómo se establece la indicación de los estudios tomográficos en pacientes politraumatizados. Materiales y métodos: Se realizó una investigación descriptiva, transversal y prospectiva. El universo estuvo constituido por 43 pacientes con diagnóstico de politrauma, que ingresaron por el Servicio de Urgencias del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, y a los cuales se les indicaron estudios tomográficos, o no, para definir conducta. Resultados: Predominó el grupo etario de entre 31 y 60 años, y el sexo de las personas atendidas con traumas complejos estuvo representado en un 83,7 % por pacientes masculinos. La combinación de traumas fue la que predominó en el universo estudiado, con un 55,8 % de aparición, y predominaron las tomografías múltiples, para un 60,4 %. Conclusiones: La indicación de tomografías múltiples en pacientes politraumatizados no estuvo justificada en el mayor porciento de los casos. La no recogida de la cinemática del trauma, ni la aplicación de las escalas pronósticas que están protocolizadas, llevaron a cometer errores en las indicaciones de complementarios imagenológicos y en la actuación. Se detectó un uso innecesario del equipo, elemento que acorta su vida útil y ocasiona daño biológico al paciente.

Introduction: Trauma implies a comprehensive form of management that requires a significant investment in two aspects: economic and educative. Polytraumatized patients are difficult to assess, diagnose and treat, as they present a high vital risk, therefore fast, comprehensive and multidisciplinary diagnosis and treatment are required. Objective: To determine how the indication of tomographic studies in polytraumatized patients is established. Materials and methods: A descriptive, cross-sectional and prospective research was carried out. The universe consisted of 43 patients with diagnosis of polytrauma, who entered the Emergency Service of the Clinical Surgical University Hospital Comandante Faustino Perez Hernandez, and who were indicated tomographic studies or not, to define behavior. Results: The age group between 31 and 60 years predominated, and the sex of the people treated with complex trauma was represented in 83.7% by male patients. Trauma combination predominated in the studied universe, with an occurrence of 55.8%, and multiple tomographies predominated, for 60.4%. Conclusions: The indication of multiple tomographies in polytraumatized patients was not justified in the highest percentage of cases. The non-collection of the kinematics of the trauma, nor the application of the prognosis scales that are protocoled, led to mistakes in the indication of complementary imaging and in the performance. An unnecessary use of the equipment was detected, an element that shortens its useful life and causes biological damage to the patient.

Hiperfiltración glomerular en el paciente traumático grave / Glomerular hyperfiltration in patients with severe trauma

Antecedentes y objetivo El aclaramiento renal aumentado o hiperfiltración glomerular (HFG) puede afectar significativamente a los resultados clínicos de los fármacos eliminados por vía renal al promover la exposición subterapéutica al fármaco. La agresión sufrida en los pacientes que presentan trauma grave supone un predisponente a manifestar HFG y la identificación de estos pacientes sigue siendo un desafío clínico. El objetivo principal de este estudio fue describir la prevalencia de HFG en una cohorte de pacientes críticos traumatizados en la primera semana de ingreso. Materiales y métodos Estudio prospectivo observacional de una cohorte de pacientes adultos ingresados en la UCI de Anestesiología del Complejo Hospitalario Universitario de Albacete (España) tras sufrir un trauma grave o politraumatismo. Se calculó el aclaramiento de creatinina (ClCr) en muestra de recolección de orina 4h a las 24, 72 y 168h de ingreso aplicando la fórmula ClCr: [Diuresis en ml (orina/4h)×Creatinina en orina (mg/dl)]÷[240 (minutos)×Creatinina en plasma (mg/dl)]. Un CrCl por encima de 130ml/min fue considerado HFG. Los análisis se realizaron con el software estadístico R versión 4.0.4. Resultados Se incluyeron 85 pacientes. La edad mediana de los pacientes fue de 51 años (RIQ 26); 68 pacientes fueron varones (78,82%). El 75,29% de los pacientes fueron politraumatizados; 61 pacientes (71,76%) presentaron HFG en algún momento de la determinación del ClCr. A las 24h de ingreso el 56,34% de los pacientes presentaron HFG con ClCr medio de 195,8ml/min, el 61,11% de los pacientes lo presentaban a las 72h con ClCr medio de 186ml/min y el 56,52% presentaban HFG a las 168h de ingreso con ClCr medio de 207ml/min. Se encontró una relación positiva importante (p=0,07) entre la HFG manifestada a las 72h y a las 168h. Se observó relación estadísticamente significativa entre este fenómeno con edades más jóvenes, puntuaciones ISS más bajas y creatininas plasmáticas más bajas (AU)

Background and objective Augmented renal clearance or glomerular hyperfiltration (GHF) can significantly affect the clinical outcomes of renally eliminated drugs by promoting subtherapeutic drug exposure. The aggression suffered in patients who suffer severe trauma is a predisposition to manifest GHF and the identification of these patients remains a clinical challenge. The main objective of this study was to describe the prevalence of GHF in a cohort of critically ill trauma patients. Materials and methods Prospective observational study of a cohort of adult patients admitted after suffering severe trauma or polytrauma in the Anesthesiology ICU of the University Hospital of Albacete (Spain). Creatinine clearance (ClCr) was calculated in a 4-h urine collection sample at 24, 72 and 168h after admission applying the formula: CrCl: [diuresis in ml (urine/4h)×creatinine in urine (mg/dl)]÷[240 (min)×creatinine in plasma (mg/dl)]. A CrCl above 130ml/min was considered GHF. The analyzes were performed with the statistical software R version 4.0.4. Results Eighty-five patients were included. The median age of the patients was 51 years (IQR 26). Sixty-eight patients were male (78.82%). 75.29% of the patients were polytraumatized. Sixty-one patients (71.76%) presented GHF at some point in the CrCl determination. At 24h of admission, 56.34% of the patients presented GHF with a mean CrCl of 195.8ml/min, 61.11% of the patients presented it at 72h with a mean CrCl of 186ml/min and 56.52% presented GHF at 168h of admission with a mean CrCl of 207ml/min. A significant positive relationship (p=0.07) was found between GHF manifested at 72h and at 168h. We observed a statistically significant relationship between this phenomenon with younger ages, lower ISS scores and lower plasma creatinines (AU)

Concordancia entre las ecuaciones de estimación del filtrado glomerular y el aclaramiento de creatinina en orina de 4horas en pacientes críticos con trauma grave / Concordance between glomerular filtration rate estimation equations and 4-hour urinary creatinine clearance in critically ill patients with severe trauma

Antecedentes y objetivo: Cada vez hay más estudios que evidencian que las ecuaciones utilizadas para conocer la tasa de filtrado glomerular estimada (TFGe) no son adecuadas para los pacientes críticos en los que se producen continuas variaciones del filtrado glomerular (FG). El método más práctico para aproximarse al estudio del FG es el cálculo del aclaramiento de creatinina (ClCr) en periodos de recogida de orina variables. El objetivo del estudio fue observar el comportamiento de las ecuaciones empleadas para estimar el filtrado glomerular cuando se aplican a la subpoblación de pacientes críticos ingresados por trauma grave y comparar el ClCr en orina recogida en un periodo de 4horas (ClCr-4h). Material y métodos: Estudio observacional que incluye pacientes ingresados por trauma grave. Se calculó el ClCr-4h y se determinó la TFGe mediante las ecuaciones de Cockcroft-Gault, Jelliffe modificada, MDRD, t-MDRD y CKD-EPI. Los resultados se expresan referidos a superficie corporal (ml/min/1,73m2). Los análisis se realizaron con el software estadístico R versión 4.0.4. Resultados: Se incluyeron 85 pacientes. La edad mediana de los pacientes fue de 51años; 68 pacientes fueron varones (78,82%). El ClCr-4h ajustado a superficie corporal (ClCr-4h ml/min/1,73m2) medio fue de 84,5ml/min/1,73m2. Hallamos correlación estadísticamente significativa de ClCr-4h/1,73m2 con la TFGe por t-MDRD. Para ClCr-4h/1,73m2 mayores de 130ml/min/m2 la ecuación de Cockcroft-Gault identifica a los pacientes correctamente de una forma estadísticamente significativa. Conclusiones: El cálculo de ClCr en el entorno de UCI proporciona datos fiables del FG, no siendo adecuado el uso de ecuaciones estimativas.(AU)

Background and objective: There is a growing body of evidence that the equations used to estimate the glomerular filtration rate (GFR) are not suitable in critically ill patients, a population whose GFR fluctuates continuously. Glomerular filtration is usually estimated by measuring urine creatinine clearance (CrCl) at various time points. The aim of our study was to evaluate the performance of the most widely used GFR calculators in the subpopulation of critically ill patients admitted for severe trauma, and to compare the results against determinations of CrCl in urine collected over a 4-hour period (4h-CrCl). Material and methods: Observational study in patients hospitalized for severe trauma. We measured the 4h-CrCl and estimated GFR using the Cockcroft-Gault, modified Jelliffe, MDRD, t-MDRD, and CKD-EPI equations, adjusting the results for body surface area (BSA) (ml/min/1.73m2). Data were analysed using R version 4.0.4. Results: A total of 85 patients were included. Median age was 51years, and 68 were men (78.82%). The mean BSA-adjusted 4h-CrCl (4h-ClCr/1.73m2) was 84.5ml/min/1.73m2. We found that GFR estimated using the t-MDRD equation correlated significantly with 4h-CrCl/1.73m2. The Cockcroft-Gault equation correlated significantly with 4h-CrCl/1.73m2 when GFR was greater than 130ml/min/m2. Conclusions: In ICU patients, glomerular filtration can be reliably estimated by determining urine CrCl, but GFR calculators are not accurate in this population.(AU)

Terapia médico-nutricional en pacientes politraumatizados: una carrera contra el tiempo.

A polytraumatized patient is defined as one who has multiple lesions involving different organs and systems, which are usually serious and lead to life-threatening respiratory or circulatory dysfunction. Traumatic stress in the polytraumatized patient results in many metabolic changes that are evident from the first days, but usually persist for weeks, requiring adequate nutritional support as they influence outcomes. Nutritional treatment should be a priority in the comprehensive treatment of polytraumatized patients since it attenuates the metabolic response to trauma and prevents the deterioration of body reserves. It should be noted that some patients present previous nutritional risk. Nutritional intervention should be considered at the same level as any other therapy that supports organic functions, especially in patients in the intensive care unit. Nutritional intervention in polytraumatized patients is a pillar of treatment that has multiple benefits and can improve prognosis. All efforts must be aimed at the early detection of malnourished patients at nutritional risk and providing timely therapies that improve clinical outcomes.

El paciente politraumatizado se define como aquel que tiene múltiples lesiones que involucran diferentes órganos y sistemas, suelen ser graves y conllevan una disfunción respiratoria o circulatoria que pone en riesgo la vida. El estrés traumático en el paciente politraumatizado da lugar a muchos cambios metabólicos que son evidentes desde los primeros días, pero suelen persistir durante semanas y exigen un adecuado soporte nutricional, ya que influyen en los desenlaces. El tratamiento nutricional debe ser una prioridad en el tratamiento integral de los pacientes politraumatizados, porque atenúa la respuesta metabólica al trauma y evita el deterioro de las reservas corporales (cabe mencionar que algunos pacientes presentan riesgo nutricional previo). La intervención nutricional debe considerarse al mismo nivel que cualquier otra terapia que apoye las funciones orgánicas, sobre todo en pacientes en la unidad de terapia intensiva. La intervención nutricional en pacientes politraumatizados es un pilar en el tratamiento que tiene múltiples beneficios y puede mejorar el pronóstico. Todo esfuerzo debe ir encaminado a la detección temprana de pacientes desnutridos o en riesgo nutricional, y proporcionar de manera oportuna terapias que mejores los desenlaces clínicos.

Glomerular hyperfiltration in patients with severe trauma.

BACKGROUND AND OBJECTIVE: Augmented renal clearance or glomerular hyperfiltration (GHF) can significantly affect the clinical outcomes of renally eliminated drugs by promoting subtherapeutic drug exposure. The aggression suffered in patients who suffer severe trauma is a predisposition to manifest GHF and the identification of these patients remains a clinical challenge. The main objective of this study was to describe the prevalence of GHF in a cohort of critically ill trauma patients. MATERIALS AND METHODS: Prospective observational study of a cohort of adult patients admitted after suffering severe trauma or polytrauma in the Anesthesiology ICU of the University Hospital of Albacete (Spain). Creatinine clearance (ClCr) was calculated in a 4-h urine collection sample at 24, 72 and 168 h after admission applying the formula; CrCl: [Diuresis in ml (urine/4 h) × Creatinine in urine (mg/dl)] ÷ [240 (minutes) × Creatinine in plasma (mg/dl)]. A CrCl above 130 mL/min was considered GHF. The analyses were performed with the statistical software R version 4.0.4. RESULTS: 85 patients were included. The median age of the patients was 51 years (IQR 26), 78.82% male. 68 patients were male (78.82%). 75.29% of the patients were polytraumatized. 61 patients (71.76%) presented GHF at some point in the CrCl determination. At 24 h of admission, 56.34% of the patients presented GHF with a mean CrCl of 195.8 ml/min, 61.11% of the patients presented it at 72 h with a mean CrCl of /min and 56.52% presented GHF at 168 h of admission with a mean CrCl of 207 ml/min. A significant positive relationship (p = 0.07) was found between GHF manifested at 72 h and at 168 h. We observed a statistically significant relationship between this phenomenon with younger ages, lower ISS scores and lower plasma creatinines. CONCLUSIONS: GHF are a common condition in critically ill patients admitted for severe trauma. We recommend the use of CrCl to assess renal function and make dosage adjustments. Studies are required to understand the clinical impact of these phenomena on drug elimination and to be able to establish the ideal dosage in those cases.

Uso de la fijación externa en el tratamiento de las fracturas de pelvis / External fixation in the treatment of pelvic fractures

El objetivo de nuestro trabajo es llevar a cabo una revisión bibliográfica sobre las fracturas de pelvis, centrándonos principalmente en el uso de la fijación externa para el tratamiento de las fracturas de pelvis en el contexto de urgencias. El principal problema con el que se encuentra el cirujano ortopédico, en el tratamiento de urgencias de las fracturas de pelvis de alta energía, es con la necesidad de realizar un tratamiento quirúrgico rápido, pero que sea lo suficientemente estable para mantener una reducción hasta que el paciente pueda ser sometido a una intervención definitiva. Se han desarrollado múltiples métodos de fijación externa con el objetivo de dar respuesta a estas necesidades. Se llevará a cabo un análisis de las diferentes opciones, así como de los diferentes trabajos publicados.(AU)

The aim of our work is to make a review of pelvis' fractures, mainly focusing in the use of the external fixation in the treatment of pelvis’ fracture in the emergency context. The main problem the orthopedic surgeon must face is the need to perform a treatment that must be fast, but also must supply enough stability to maintain a reduction of the fracture until the patient can have the final surgery done. There are many methods of external fixation, that have been developed in order to achieve these objectives. We will make an analysis of the different options and a review of the literature.(AU)

Tranexamic acid use in severely injured patients, is it always appropriate?

Recently, it has been suggested that tranexamic acid should be administered only in those patients with hyperfibrinolysis determined using viscoelastic assays, as severely injured patients may present with fibrinolytic shutdown. However the last European guidelines on management of major bleeding and coagulopathy following trauma endorse the use of tranexamic acid to the trauma patient who is bleeding or at risk of significant hemorrhage as soon as possible without waiting for viscoelastic results. We present a severely blunt trauma patient treated with on-scene administration of tranexamic acid that developed immediate pulmonary embolism.

Ácido tranexámico en el paciente politraumatizado grave, ¿está siempre indicado? / Tranexamic acid use in severely injured patients, is it always appropriate?

Recientemente se ha sugerido la administración de ácido tranexámico sólo en aquellos pacientes con hiperfibrinólisis documentada con métodos viscoelásticos, ya que los pacientes politraumatizados graves pueden presentar una disminución de la fibrinólisis. Sin embargo, las últimas guías clínicas sobre el manejo de la hemorragia y coagulopatía tras un trauma recomiendan el uso de ácido tranexámico en todo paciente sangrante, o con posibilidad de sangrar, lo más precozmente posible sin esperar los resultados de los métodos viscoelásticos. Presentamos el caso de un trauma cerrado grave que recibió ácido tranexámico prehospitalariamente y desarrolló un embolismo pulmonar inmediato.(AU)

Primer registro de trauma en Chile: análisis de 2 años en un hospital público / First trauma registry in Chile: 2 years analysis in a public hospital

Resumen Introducción: El trauma representa un verdadero reto para los sistemas sanitarios por ser un gran problema de salud pública. En Chile se desconoce el manejo del paciente politraumatizado. Objetivo: Describir los resultados del primer registro de trauma (RT) en línea, en los pacientes que se atienden en el Hospital Dr. Sótero del Río durante los primeros dos años de la implementación. Materiales y Método: Se recoge información prospectiva en un registro en red, sobre pacientes víctimas de trauma, ingresados al Hospital Dr. Sótero del Río durante dos años. Estas variables involucran todo el proceso de atención clínica desde el ingreso al alta o fallecimiento. Resultados: En dos años, se registran 3.515 ingresos de pacientes víctima de trauma. Entre estos, el 81,3% son hombres. El 27% sufre trauma penetrante y 59% cerrado. Destacan más lesiones por arma de fuego que por arma blanca. El 18,4% de los pacientes ingresados tiene un el Injury Severity Score (ISS) mayor a 15 puntos. 34 pacientes ingresan en paro cardiorrespiratorio y 7,3 % lo hace hipotenso. Se realizan 1.856 tomografías y el 54,4% requiere cirugía de urgencia. Ingresan 692 traumas torácicos, 654 abdominales, 1.550 de extremidades, 687 lesiones en cráneo y 190 traumas cervicales. Se activa el protocolo de transfusión masiva en el 3,1% de los ingresos. El 8,3% utiliza la unidad de paciente crítico y la mortalidad es de 2,9%, teniendo como primera causa el trauma encéfalocraneano y segunda el shock hemorrágico. Conclusiones: Nuestro hospital tiene una gran incidencia de trauma. La implementación de un RT permite conocer la dimensión y evaluar el proceso asistencial en torno al paciente víctima de trauma. Es necesario dirigir recursos e implementar capacitación en los centros de alto volumen de trauma, además, de continuar con la extensión de la herramienta como estrategia de monitorización multicéntrica.

Introduction: Trauma represents a real challenge for health systems because is a major public health problem. In Chile, the management of polytrauma patients is unknown. Aim: Describe the results of the first online trauma registry; in patients treated at the Dr. Sótero del Río Hospital during the first two years of implementation. Materials and Method: Prospective information is collected in a network registry, about trauma victims, admitted to Dr. Sótero del Río Hospital for two years. These variables involve the entire clinical care process from admission to discharge or death. Results: 3.515 admissions of trauma victims are registered in two years. Among these, 81.3% are men. 27% suffered penetrating trauma and 59% closed. They emphasize larger injuries by firearm than by bladed weapon. 18.4% of admitted patients have ISS greater than 15 points. 34 patients enter cardio-respiratory arrest and 7.3% make it hypotensive. 1,856 CT scans are performed and 54.4% require emergency surgery. They admitted 692 thoracic trauma, 654 abdominal, 1550 limb, 687 skull injuries and 190 cervical trauma. The massive transfusion protocol is activated at 3.1% of the admissions. 8.3% use the critical patient unit and mortality is 2.9%, with cranial brain trauma as the first cause and hemorrhagic shock as a second cause. Conclusions: Our hospital has a high incidence of trauma. The RT implementation allows us to know the dimension and assess the care process about the trauma patient. It is necessary to direct resources and implement training in high-volume trauma centers, as well as continuing with the extension of the tool as a multi-center monitoring strategy.

Sistemática en el Tratamiento Quirúrgico de las Fracturas Panfaciales Aplicado a un Caso Clínico De Alta Complejidad / Systematic in the Surgical Treatment of Panfacial Fractures Applied to a Highly Complex Clinical Case

RESUMEN: Las fracturas panfaciales son aquellas que afectan de forma simultánea al tejido óseo de dos o más tercios del rostro. El manejo inicial de estos pacientes es resolver o estabilizar las urgencias médico - quirúrgicas que puedan presentar, debido a que la gran mayoría de estas fracturas están asociadas a traumatismos de alta energía cinética, las que determinan la presencia de lesiones concomitantes que pueden comprometer la vida del paciente. El tratamiento quirúrgico de las fracturas panfaciales puede abarcar desde la intervención quirúrgica inicial de control de daños, estabilización, reducción y fijación quirúrgica de los segmentos fracturados mediante osteosíntesis hasta intervenciones mediatas para la reconstrucción de los tejidos afectados por el traumatismo. Para el tratamiento de las fracturas panfaciales existe una sistemática quirúrgica que tiene por objeto contener y/o minimizar daños agudos y permitir una reducción morfológica y funcional. Reportamos un caso clínico de fractura panfacial cuyo tratamiento siguió esta sistemática terapeútica.

ABSTRACT: Panfacial fractures affect bone tissue in two or more thirds of the face simultaneously. The initial management of these patients is to resolve or stabilize the medical-surgical emergencies that they may present. Most of these fractures are associated to trauma of high kinetic energy, which determine the presence of concomitant inju- ries that can compromise the life of the patient. The surgical treatment of panfacial fractures may include from the initial surgical intervention of damage control, stabilization, reduction and surgical fixation of fractured segments through osteosynthesis, to mediate the reconstruction of tissues affected by the trauma. For the treatment of panfacial fractures there is a surgical approach that aims to contain and/or minimize acute damage and allow for morphological and functional reduction. We report a clinical case of panfacial fracture whose treatment followed this therapeutic approach.

Factor tiempo en la atención inicial del paciente politraumatizado / Factor time in the initial attention of the poly-traumatized patient

RESUMEN Introducción: el politraumatismo por si solo constituye uno de los problemas más grandes de la sociedad moderna. Las lesiones traumáticas en Cuba aparecen en el quinto lugar entre las causas globales de muerte para todas las edades. Objetivo: determinar cómo incidió el factor tiempo en la organización de las acciones para la atención de urgencia al paciente politraumatizado. Materiales y método: se realizó un estudio observacional, conformado por 183 pacientes politraumatizados, atendidos en la Unidad de Cuidados Intensivos Emergentes del Hospital Provincial". José R. López Tabrane " de Matanzas, durante el año 2014. Las variables a considerar fueron: edad, sexo, tiempo en que recibieron las primeras acciones, tiempo de llegada al Hospital, factores asociados que influyeron en la aparición de injuria secundaria. Se utilizó la técnica estadística de análisis de distribución de frecuencias. Resultados: el mayor porcentaje de los pacientes (82,6 %) acudieron 4-6 h después de sufrido el traumatismo. Aparecieron factores como la hipotensión, la hipoxia (66,1 y 50,2 %) respectivamente, que tuvieron lesiones asociadas y fueron valoradas en la primera hora del traumatismo. Conclusiones: el trauma severo es una de las entidades prevenibles que más vida cobra en la sociedad. El sexo masculino y edades más productivas de la vida fueron los que más morbimortalidad presentaron. El hecho de que la mayor cantidad de estos pacientes arribaron al Hospital después de la hora dorada, propició un mayor número de complicaciones por el no control a tiempo de los elementos que forman la injuria secundaria (AU).

ABSTRACT Introduction: polytrauma, by itself, is one of the biggest problems of the modern society. Trauma lesions in Cuba are in the fifth place among the death global causes for all age groups. Objective: to determine how time factor had an impact in the actions organization for the emergency care to polytrauma patient. Materials and method: an observational study was performed in 183 poly-trauma patients who attended the Intensive Care Unit of the Provincial Hospital "Jose Ramón López Tabrane" of Matanzas during 2014. The considered variables were: age; sex; time of receiving the first actions; time of arrival to the hospital; associated factors influencing in the appearance of secondary injury. The authors used the statistic technique of analysis of frequency distribution. Results: the highest percent of patients (82.6 %) assisted the consultation 4-6 hours after suffering the trauma. There were found factors like hypotension and hypoxia (66.1 and 50.2 % respectively that had associated lesions and were assessed in the first hour of the trauma. Conclusions: acute trauma is one of the preventable entities taking more lives in the society. Male sex predominated and the more productive ages of life were the ones presenting more morbid-mortality. The fact that the biggest quantity of these patients arrived to the hospital after the golden hour favored a higher number of complications due to the untimely control of the elements forming the secondary injury (AU).

Assessment of clinical parameters of the polytraumatized patient as predictors of hospital expenditure and of its distribution. / Valoración de parámetros clínicos del paciente politraumatizado como predictores del gasto hospitalario y de su distribución.

INTRODUCTION: Traumatic pathology continues to represent an important socio-health problem. The aim of the study was to assess the clinical predictors of total expenditure, as well as to analyze which components of the cost are modified with each clinical parameter of the polytraumatized patient. MATERIAL AND METHODS: Retrospective study of 131 polytrauma patients registered prospectively. A statistical analysis was carried out to assess the relationship between clinical parameters, the total cost and the cost of various treatment components. RESULTS: The total cost of hospital admission was 3,791,879 euros. The average cost per patient was € 28,945. Age and gender were not predictors of cost. The scales ISS, NISS and PS were predictors of the total cost and of multiple treatment components. The AIS of Skull and Thorax predicted a higher cost of admission to ICU and Total Cost. The AIS of lower limbs was associated with greater spending on facets of treatment related to surgical activity. DISCUSSION: There are clinical parameters that are predictors of the treatment cost of the polytraumatized patient. The study describes how the type of trauma that the patient suffers modifies the type of expenses that will present in their hospital admission. CONCLUSIONS: Polytraumatized patients with severe multisystem injury present increased costs in multiple components of the treatment cost. Patients with TBI or chest trauma present a higher cost for admission to ICU and those with orthopaedic trauma are associated with greater expenditure on surgical activity.
