Sonographic evolution of the superficial vein thrombosis of the lower extremity.

BACKGROUND: Superficial venous thrombosis (SVT) is a common clinical problem across various treatment settings. SVT shares risk factors with deep venous thrombosis (DVT) and carries a risk of thromboembolic complications, greater than previously expected. Little is known about the pathophysiology, resolution and recurrence of this disease. OBJECTIVES: The objective of the present study was to describe the natural course of SVT, and factors correlated with the progression or resolution of the thrombus. METHODS: We included 218 patients with a recent diagnosis of SVT that were consecutively referred to a thrombosis clinic from the Emergency Department (ED) between January 2016 and April of 2018. RESULTS: The resolution of the thrombus prior to discharge was correlated to gender (female 73.8% vs. male 57.5%, p = 0.015), presence of varicose veins (62.4% vs. 46.4, p = 0.026), absence of family or personal history of thrombosis (98% vs. 91.3%, p = 0.021). The factor most correlated to thrombus resolution prior to discharge was the result of the 2nd ultrasound (improvement 83.9% vs. 16.1%, p < 0.001) immediately after initiation of heparin treatment. In the multivariate analysis, a high thrombus burden in the early follow-up ultrasound was the most significant predictive variable with prior to discharge recanalization (B = 20.9, 95% CI 9.8-44.7; p < 0.001). CONCLUSION: The follow-up of SVT with duplex lower extremity ultrasound allows us to monitor the evolution and early identify residual thrombosis, as a marker of hypercoagulability and recurrence. This study offers new perspectives for future research, necessary to improve the management of this disease, to reduce long-term complications.

Transfusión en Urgencias: algo más que una transfusión de sangre / Transfusions in the Emergency department: more than a blood transfusion

La elevación del nivel de hemoglobina y de hematocrito con transfusiones sanguíneas ha sido el estándar de oro para el tratamiento de la anemia grave. Sin embargo, la indicación para la transfusión de concentrado de hematíes se basa meramente en unos marcadores analíticos, como el nivel de hemoglobina o hematocritos, en lugar de basarse en la clínica (según las guías de práctica clínica), en la implementación de regulaciones legales o en los consensos alcanzados por los comités de transfusión de los hospitales. El objetivo de este estudio multicéntrico es reevaluar la idoneidad de la indicación de transfusión de concentrado de hematíes y los volúmenes transfundidos en los servicios de urgencias. Se plantea un diseño observacional multicéntrico y transversal en 2centros participantes: el Hospital Universitario de La Paz y el Hospital de Salamanca. En total se obtuvieron datos de 381 pacientes; 220 eran hombres (57,74%), con una edad promedio de 71,4±14,0 años y 161 eran mujeres (42,26%) con una edad promedio de 75,3±15,3 años (p < 0,001). Las enfermedades subyacentes más prevalentes en los pacientes que recibieron transfusión fueron las cardiológicas, que incluyeron hemorragia debido a la terapia antiagregante plaquetaria o anticoagulante (57,7%), las hematooncológicas (15,3%) y las neurológicas. Solo el 54,9% (209/381) de las prescripciones de transfusión se consideraron apropiadas, con diferencias significativas observadas según la indicación

Increasing haemoglobin and haematocrit levels with blood transfusions has been the gold standard for treating severe anaemia; however, the indication for transfusing concentrated red blood cells is based merely on a few laboratory markers, such as haemoglobin and haematocrit levels, rather than based on the symptoms according to clinical practice guidelines, the implementation of legal regulations and the consensus achieved by the hospitals' transfusion committees. The aim of this multicentre study was to reassess the suitability of the indication for transfusing concentrated red blood cells and the volumes transfused in emergency departments. We established an observational, multicentre, cross-sectional design with 2 participating centres: the La Paz University Hospital and the Hospital of Salamanca. In total, we obtained data from 381 patients, 220 (57.74%) of whom were men with an average age of 71.4±14.0 years and 161 (42.26%) of whom were women with an average age of 75.3±15.3 years (P<.001). The most prevalent underlying diseases in the patients who underwent transfusions were heart disease, which included haemorrhaging due to antiplatelet or anticoagulant therapy (57.7%), haemato-oncologic (15.3%) diseases and neurological disease. Only 54.9% (209/381) of the prescriptions for transfusion were considered appropriate, with significant differences according to the indication

Reaffirmation of the importance of follow-up ultrasound studies in patients with high D-dimers and clinical suspicion of vein thrombosis.

BACKGROUND: Venous thromboembolism is a common disease seen in the emergency department and a cause of high morbidity and mortality, constituting a major health problem. OBJECTIVES: To assess the potential benefit of follow-up ultrasound of patients who attended the emergency department with suspected superficial venous thrombosis or deep venous thrombosis and were found to have an initial negative whole-leg (or arm) ultrasound study. METHODS: This retrospective study included patients aged 18 years or older who were consecutively referred to a thrombosis clinic from the emergency department, with abnormal D-dimer test and moderate to high pre-test probability of deep venous thrombosis (Well's score ≥ 1), but a negative whole-leg (or arm) ultrasound. Demographic characteristics, symptom duration, laboratory and ultrasound data were recorded. At one-week follow-up, an experienced physician repeated ultrasound, and recorded the findings. RESULTS: From January 2017 to April 2018, 54 patients were evaluated. The mean age was 66.8 years (SD 15.0) and 63% were women. The average D-dimer was 2159.9 (SD 3772.0) ng/mL. Ultrasound abnormalities were found in 12 patients (22.2%; 95% confidence interval of 12.5 to 36.0%), with 4 patients having proximal deep venous thrombosis, distal deep venous thrombosis in 2 patients and superficial venous thrombosis in 6 patients. We did not find any significant differences in demographic characteristics, venous thromboembolism risk factors or laboratory parameters between patients with negative and positive follow-up ultrasound. CONCLUSIONS: These preliminary findings suggest that a negative whole-leg (or arm) ultrasound in addition to an abnormal D-dimer in moderate to high deep venous thrombosis pretest probability patients, might be an insufficient diagnostic approach to exclude suspected deep venous thrombosis or superficial venous thrombosis. Confirmation of this higher than expected prevalence would support the need to repeat one-week ultrasound control in this population.

Safety and effectiveness of a prothrombin complex concentrate in approved and off-label indications.

OBJECTIVE: To evaluate the effectiveness and safety of prothrombin complex concentrates (PCCs) in approved and off-label indications. BACKGROUND: PCCs are approved for the urgent reversal of vitamin K antagonists (VKAs). Data concerning the efficacy, safety and dosing for off-label indications are limited, but they are included in massive bleeding protocols. METHODS: This was a retrospective review of cases treated with four-factor PCCs (4F-PCCs) between January 2009 and 2016. Efficacy end-points include: (i) VKA reversal efficacy assessed by international normalised ratio (INR) normalisation (<1·5) and (ii) clinical efficacy as bleeding cessation and/or decreased number of transfused blood components and 24-h mortality in bleeding coagulopathy. The safety end-point is the incidence of thromboembolic events. RESULTS: A total of 328 patients were included (51·8% male, median age 78 years old). Indications were as follows: VKA reversal (66·6%), bleeding coagulopathy (30·5%) and direct anticoagulant (DOAC) reversal due to bleeding (2·5%). VKA reversal was effective in 97·1% of patients, and 76·5% demonstrated complete reversal (INR < 1·5); only 34·3% patients needed hemoderivatives. Prior to emergency procedures, PCCs achieved global responses in 83% of patients, with no bleeding complication during intervention. DOAC reversal was effective in 88·9% of patients. Bleeding cessation was associated with the dose administered (P = 0·002). In coagulopathy bleeding, haemorrhage cessation, established by the International Society of Thrombosis and Haemostais (ISTH) definition, occurred in 56·7% of massive bleeding events and in 42·5% of other coagulopathies; 24-h mortality was 30%, mainly related to active bleeding. Ten thrombotic episodes were observed (3·1%). CONCLUSION: 4F-PCC was effective as adjuvant treatment with an acceptable safety profile, not only for the emergent reversal of VKAs but also for refractory coagulopathy associated with major bleeding.

Utilización de los servicios de urgencias en zonas rurales y urbanas / Use of emergency departments in rural and urban areas in Spain

Objetivos: Describir la utilización de los servicios de urgencias (SU) y analizar las diferencias entre zonas rurales y urbanas. Material y métodos: Con la Encuesta Nacional de Salud de los años 2006 y 2011 se describen los perfiles de los pacientes que tienen visitas al SU según tamaño del municipio de residencia y se identifican las variables asociadas con tener una visita a los SU para determinar el efecto del tamaño del municipio de residencia. Resultados: En ambos años, la mayor utilización de SU se observa en las personas que utilizan más Atención Primaria u hospitales, que tienen peor salud autopercibida y estado funcional, con más enfermedades crónicas, de clases sociales más bajas, y de menor edad. Ajustando por el resto de las variables, los residentes en municipios de más habitantes o capitales de provincia tienen una mayor frecuentación de SU que los residentes en municipios más pequeños, que tienen una mayor utilización de SU públicos y no hospitalarios, que los residentes en zonas urbanas. Discusión: Existe una utilización más elevada de los SU por los habitantes de zonas urbanas que no puede justificarse por su peor estado de salud, lo que indicaría no una infrautilización en zonas rurales, sino sobreutilización en zonas urbanas (AU)

Objectives: Describe the use of emergency departments (ED), and analyse the differences in use between residents in rural and urban areas. Material and methods: Using data from the National Health Survey of 2006 and 2011, the profiles of patients with ED visits by population size of place of residence were obtained. The variables associated with making one visit to the ED were also evaluated, in order to determine the effect of the population size of place of residence. Results: A higher use of ED is observed in persons with a higher frequency of use of Primary Care and hospital admissions, and increases with worse self-perceived health and functional status, with more chronic diseases, in people from lower social classes, and younger ages. Adjusting for the other variables, residents in larger cities have a higher use of ED than residents in rural areas, who show a higher use of public and non-hospital based ED, than residents in urban areas. Discussion: There is a higher use of ED by inhabitants of urban areas that cannot be justified by a worst health status of that population. This tends to indicate that the use of ED is not under-used in rural areas, but overused in urban areas (AU)

Injury patterns from major urban terrorist bombings in trains: the Madrid experience.

BACKGROUND: Terrorist urban mass casualty incidents (MCI) in the last 3 years have targeted commuter trains at rush hour, producing large numbers of casualties. Civilian care providers are usually not familiar with the types of blast injuries sustained by victims of these MCI. METHODS: We focus on the injury patterns sustained by casualties of the Madrid, 11 March 2004, terrorist bombings, at the seven hospitals that received most victims. Data were gathered of casualties who had injuries other than superficial bruises, transient hearing loss from barotrauma without eardrum perforation, and/or emotional shock. The degree of severity in critical patients was assessed with the ISS. RESULTS: The bombings resulted in 177 immediate fatalities, 9 early deaths, and 5 late deaths. Most survivors had noncritical injuries, but 72 (14%) of 512 casualties assessed had an Injury Severity Score (ISS) >15. The critical mortality rate was of 19.5%. The most frequently injured body regions were the head-neck and face. Almost 50% of casualties had ear-drum perforation, and 60% of them were bilateral. There were 43 documented cases of blast lung injury, with a survival rate of 88.3%. Maxillofacial and open long-bone fractures were most prevalent. Gustillo's grade III of severity predominated in tibia-fibular and humeral fractures. Upper thoracic fractures (D1-6 segment) represented 65% of all vertebral fractures and were associated with severe blast to the torso. Severe burns were uncommon. Eye injuries were frequent, although most were of a mild-to-moderate severity. Abdominal visceral lesions were present in 25 (5%) patients. A multidisciplinary approach was necessary in most operated patients, and orthopedic trauma procedures accounted for 50% of the caseload in the first 24 h. CONCLUSIONS: Ninety-three percent of the fatalities of the Madrid trains terrorist bombings were immediate, and most survivors had noncritical injuries. Closed doors increased the immediate fatality rate in the trains. Severely wounded casualties presented specific patterns of injuries, some of them life-threatening and unusual in other types of trauma mechanisms. Ear-lobe amputations and upper thoracic spine fractures were markers of critical injuries.
