Filter by:The LockeT II study is a single center, prospective randomized study. It is intended to study the effectiveness of using LockeT device to gain hemostasis after venous procedures as compared to Manual Compression (MC). Approximately 110 patients will be enrolled.
This study is designed as a randomized, double-blind, sham-controlled, single-center research study in which healthy adults will be randomized 1:1 into one of two experimental groups, to receive transcutaneous auricular vagus nerve stimulation (taVNS) targeting either the auricular branch of the vagus nerve (ABVN) or tAN, which targets the ABVN and the auriculotemporal nerve (ATN): 1. Group 1: Sham taVNS followed by active taVNS 2. Group 2: Sham tAN followed by active tAN Participants will receive 30 minutes of sham stimulation (taVNS or tAN), followed by active stimulation (taVNS or tAN). Blood biomarkers (local and systemic) will be measured before and at several timepoints after stimulation to measure the molecular and cellular effects of the device.
Adequate coagulation measured using activated clotting (ACT) is important during vascular and cardiac surgeries. Unfractionated heparin is the most common anticoagulant used. For point of care testing, under supervision of biology department, the investigators use Hemochron Signature Elite®(HSE) (Werfen®-Barcelona Spain) to determine coagulation during cardiac surgery under Cardiopulmonary Bypass (CPB), with arterial or venous blood. The dosage of heparin varies according to this result, throughout the CPB. On the Connect Manager® software (Livanova®, Italy) which records all the data of a CPB, it is mandatory to inform, during an ACT, the sampling site in arterial or venous. The chemical compositions of arterial blood and venous blood are different (O2, Co2…) Even if the qualities of coagulation in vivo are identical, what happens when they are chemically analyzed using the medical device HSE ? Can we trust the results of this device to secure anticoagulation under CPB? Are the results affected by the sampling site? The objective of this study is to compare the reliability of hemostasis control , during cardiac surgery under cardiopulmonary bypass, for both venous and arterial blood. Effective and controllable anticoagulation is mandatory during cardiac surgeries under extracorporeal circulation. The monitoring of the effectiveness of heparin is carried out, in our center, using the Hemochron Signature Elite® (HSE) medical device, which measures the ACT (Activated Clotting Time). There is no comparative study between hemostasis of venous blood, versus arterial blood, with this point of care device.
This study is intended to document clinical effectiveness and safety pertaining to use of a new endoscopic clipping device MANTIS™ when used for hemostasis, closure, anchoring and marking.
The present post-market surveillance study aims to evaluate the safety and effectiveness of the Angio-SealTM VIP VCD in patients undergoing endovascular procedures via femoral access in real-world setting.
The aim of this study is to assess the efficacy of the ARISTA AH for restoring hemostasis following a long segment posterior spinal fusion.
With the help of a standardized questionnaire, an increased risk of bleeding due to pre-existing hemostasis disorders in the site-specific patient population will be detected and the corresponding enhanced diagnostic measures will be initiated. The planned prospective observational study should i.) systematically investigate the results of this procedure and ii.) allow a comparison with a retrospective perioperative cohort that was cared for at the Benjamin Franklin Campus before the introduction of the questionnaire. Due to the campus structure with a large vascular surgery center as well as a large urological, general and trauma surgery department, a high number of multimorbid patients with pre-existing disorders of primary hemostasis, mainly caused by medication or secondary diseases, is to be expected. In the following, the feasibility of the required measures in clinical routine (measured by the frequency of actual changes or modifications of the initially planned perioperative procedure, the adequate implementation of indicated diagnostic measures, etc.) will be examined.
The ACCEL® Absorbable Hemostat Powder Clinical IDE Trial is designed as a prospective, multi-center, randomized, non-inferiority, controlled pivotal clinical trial to evaluate the safety and efficacy of the ACCEL® Absorbable Hemostat Powder as compared to gelatin sponge, for achieving hemostasis in subjects undergoing cardiovascular, liver, or soft tissue surgery, when control of oozing to moderate bleeding by standard surgical techniques is ineffective and/or impractical.
The understanding of haemostasis and inflammation cross-talk has gained considerable knowledge during the past decade in the field of arterial and venous thrombosis. Complex and delicately balanced interaction between coagulation and inflammation involve all cellular and humoral components. Elements of the coagulation system such as activated thrombin, fibrinogen or factor Xa may increase inflammation by promoting the production of proinflammatory cytokines, chemokines, growth factors and adhesion molecules that lead to a procoagulant state amplifying the pathological process. Recent evidence supports inflammation as a common pathogenic contributor to both arterial and venous thrombosis, giving rise to the concept of inflammation induced thrombosis. Patients with infection of COVID-19 and severe pneumoniae seem to have higher risk of thromboembolism. The purpose of this project is to analyze hemostasis and coagulation of every hospitalized patient with infection of COVID-19. Blood sample for coagulation and hemostasis analysis will be collected on every patient hospitalized in Amiens hospital for COVID-19 infection. Thrombin time, factors V and II, fibrin/fibrinogen degradation products, antithrombin will be assessed every week. Anticardiolipin, anti-beta2 glycoprotein I and anti-annexin A2 antibodies IgG and IgM at day of admission and at fourth week after admission will be assessed. SARS-CoV2 viral load and serodiagnosis will be performed at the same time. At the same time venous ultrasound to diagnose thrombosis will be performed.
- Previous in vitro and in vivo studies detected the Hemopatch Sealing Hemostat® to be a new versatile, self-adhering hemostatic sealing pad consisting of a polyethylene glycol-coated collagen. - Initial study assessed that Hemopatch Sealing Hemostat® can be applied to seal almost any bleeding surface encountered during a range of procedures. The Authors shown that the device is eminently capable in both via laparotomy and laparoscopic approaches, and in patients with impaired coagulation or highly variable anatomies. They support the ease-of-use, application, and immediate hemostatic effect of the patch across a broad range of surgical settings and clinical applications, including solid organ, gastrointestinal, biliopancreatic, endocrine, cardiovascular, and urologic surgeries. - In a recent published case report the authors reported the feasibility in using Hemopatch Sealing Hemostat® for the management of a myocardial wound, performing the procedure on cardiopulmonary bypass, which meant the patient had to be heparinized. Despite these major risk factors for bleeding Hemopatch Sealing Hemostat® managed to contain bleeding and seal the wound without needing any suture. These initial results lead up to future randomized clinical trials with more extensive follow-up to assess which is the real contribution of Hemopatch Sealing Hemostat to reduce postoperative bleeding complications in cases where mechanical or energy-driven hemostasis is not possible or insufficient.
