Filter by:In this study, four different devices which stimulate the blood in the lower extremities are used in ten healthy persons while measuring the blood flow with ultrasound. The aim is to study the haemodynamic effects in the lower extremities of each modality and also to compare those effects between the four modalities in order to identify those which most effective than the others.
The randomized clinical study aimed to assess the efficacy and safety of standard anticoagulation with rivaroxaban in combination with diosmin compared to the isolated use of standard rivaroxaban for prolonged therapy of acute femoro-popliteal deep vein thrombosis reflected the speed of deep vein recanalization and incidence of post-thrombotic syndrome.
VTE associated harm is underappreciated among hospitalized patients and may be associated with missed doses of VTE prophylaxis medications. In order to ensure best practices, and administer a defect-free VTE prevention nurses must understand and educate patients on the importance of the VTE prophylaxis. We propose to conduct a randomized trial comparing the effect of a validated, real-time patient education bundle (PEB), to a program of nurse feedback and coaching (NFC) provided by nurse leaders.
This is a retrospective study performed on medical records, in order to compare the number of venous thromboses, the surgery duration, the complications rate and the duration of anastomosis in breast reconstructive surgeries by the DIEP (Deep Inferior Epigastric Perforator Flap) technique, with or without the use of a venous coupler.
The rates of Venous thromboembolism (VTE) after orthopedic surgery are as high as 40-60% without prophylactic measures. Enoxaparin, a low-molecular-weight heparin, produces an anticoagulant effect by binding antithrombin, thereby accelerating antithrombin's inactivation of coagulation factor Xa (FXa), thus decreasing the likelihood of clot formation. Despite standard dosing enoxaparin prophylaxis, VTE rates in post-operative orthopedic trauma patients remain as high as 12.2%.The investigators will examine enoxaparin pharmacokinetics and test whether a clinical protocol for real-time enoxaparin dose adjustment can favorably alter the proportion of patients with in-range anti-Factor Xa (aFXa) levels. Outcomes will include peak and trough steady-state aFXa levels in response to standard and escalated doses of enoxaparin and the incidence of venous thromboembolism and bleeding events post-surgery. In the trauma and orthopaedic populations, patients with low initial aFXa levels are significantly more likely to develop deep venous thrombosis. Thus, this study has important implications for appropriate enoxaparin dose magnitude and frequency, and may ultimately help to decrease the substantial morbidity and mortality associated with post-operative VTE.
A preliminary clinical usability study to assess design, comfort, wearability, and acceptance of Recovery Force's Deep vein thrombosis (DVT) cuff
This study has two aims. 1. Deep venous thrombosis (DVT) is a common suspected medical condition. If it cannot be excluded clinically and using D-dimer, ultrasound examination is required. An option for traditional radiologist-performed ultrasound is a 2-point compression ultrasound (2-CUS). The safety of this technique is proven. However there does not exist any data on costs comparing traditional and 2-CUS pathways in primary health care. This study will evaluate the total cost of both pathways by conducting a cost-minimization analysis. It will also study the effect of a simple ultrasound education on the referrals to hospital due to suspected DVT. Hypothesis 1: Short education in ultrasound will reduce significantly referrals to hospital and save resources. 2. Length of stay (LOS) in emergency department (ED) is related to increased mortality, morbidity, prolonged hospital stay and probably patient satisfaction. LOS of patients with a point-of-care ultrasound (POCUS) performed by an emergency physician (EP) will be compared to those that have a radiology performed ultrasound examination. Further examination and accuracy of POCUS will be noted. Hypothesis 2: POCUS can shorten LOS significantly in selected clinical conditions
The aim of this pilot study was to assess venous flow parameters in patients following total hip arthroplasty, comparing an intermittent pneumatic compression foot device with a portable neuromuscular electrostimulator device. Assessments were performed in a single sitting before hospital discharge, between days 1 to 4 post operatively. The total duration of participation for each patient who completed the study was approximately 2.5 hours.
This VA QUERI Partnered Evaluation Initiative will evaluate the impact of an immersive Point-of-care Ultrasound (POCUS) Training Course on provider skill acquisition and retention; the frequency of POCUS use by trained providers; and the barriers/facilitators to POCUS in the VHA. Data sources include pre- and post-course assessment tools, medical coding data, and course evaluations. Providers that participate in the POCUS Training Course will be compared to control providers from wait-listed facilities. Additionally, participating facilities vs. wait-listed facilities for the POCUS Training Course will be compared. Findings from this project will guide ongoing efforts of the investigators' operating partners, VA Specialty Care Centers of Innovation (SCCI) and the VA Simulation Learning and Research Network (SimLEARN), to develop a national POCUS training program and facilitate implementation of POCUS use system-wide in the VA healthcare system.
Deep venous thrombosis (DVT) represents a major problem in intensive care unit (ICU) patients. Despite the use of recommended pharmacological prophylaxis with low molecular weight heparin (LMWH), the incidence of DVT during ICU stay has been reported between 5 and 15 %. The incidence may vary due to many factors, for example the type of ICU population, the type of protocol of pharmacological prophylaxis and also the type of diagnostic approach. Before formerly planned clinical study targeted to lower DVT incidence by individualizing the dose of LMWH, the investigators decided to evaluate the real DVT incidence in the investigated ICU. The prevalence and incidence will be assessed by ultrasound testing in general ICU patients. on the sample of 200 patients. The investigators hypothesize DVT incidence of 5 %. The compliance to the local DVT prophylaxis protocol will be also evaluated.
