The Effectiveness of Ankaferd Blood Stopper in the Management of Traumatic Bleeding

Bleeding Disorder

The objective of this study was to prospectively compare effectiveness of Ankaferd Blood Stopper (ABS) with dry sponges in cessation of bleeding in adult trauma cases with external bleeding due to extremity lacerations. Methods: The study was conducted on patients with bleeding associated with extremity lacerations. All consecutive patients presented to the emergency department of the high-volume training hospital in Istanbul were recruited within the study period

The Fear F8ctor Study - Does Fear Induce a Blood Curdling State?

Blood Coagulation Disorder

For centuries the term "blood curling" has been used to describe extreme frightening situations. However, the origin of this ancient theory has never been studied and it remains unknown if fear induces the coagulation system.The objective was to explore the effects of acute fear on the coagulation system while sitting still. In a crossover study design healthy subjects will be exposed to a horrifying e.g. scary movie followed by a dull e.g. flat movie which is shown at least 1 week after the first movie on the same day of the week at the same time of the day. Participants will be recruited among students from the Leiden University Medical Center. Blood will be drawn from the cubital vein 10 minutes before the first movie, directly after the first movie. The same will be done 10 minutes before and directly after the second movie. Blood is drawn by using a needle puncture. Individual markers of coagulation activity will be determined from the blood samples. Pulse rates will be measured and an anxiety/fear score will be collected from each student for both movies.

Clinical and Economic Implications of Genetic Testing for Warfarin Management

Blood Coagulation Disorders

The purpose of this study is to explore how knowing genes that individuals inherit from their parents can make warfarin dosing more safe and effective. This study is being done to determine whether providing doctors with data on the genes their patients inherited and warfarin dosing recommendations based on those genes affects the costs and outcomes of care and after hospitalization for patients from different ethnic/racial backgrounds, and how physicians use this information in decision making.

An Evaluation of the Pharmacokinetics and Pharmacodynamics of Oral Dabigatran Etexilate in Hemodialysis...

Blood Coagulation Disorders

Patients with end stage renal disease carry a high risk for atrial fibrillation (AF) and require oral anticoagulant therapy for prevention of stroke. Often, the oral anticoagulant, warfarin sodium, is prescribed. Managing dialysis patients on warfarin can be fraught will difficulties given the multitude of drug and food interactions, need for frequent coagulation monitoring and dosage adjustment, and concern that warfarin enhances vascular calcification in dialysis patients. Recently, dabigatran etexilate, a direct oral thrombin inhibitor, has been approved for use in AF patients with normal renal function. Since many drugs are eliminated by the kidneys and removed from the plasma during dialysis, it is important to determine proper drug dosing in hemodialysis patients through evaluating pharmacokinetics.

ROTEM and Dietary Supplements

Dietary SupplementsBleeding Tendency; Due to Coagulation Defect

Dietary Supplements can affect platelet activation and aggregation, which could result in bleeding tendencies. This study wishes to evaluate the influence that these supplements has on platelet function using Rotational thromboelastometry.

Effect of the Use of Anticoagulant Therapy During Hospitalization and Discharge in Patients With...

Covid19Pneumonia2 more

Viral infections provoke the systemic inflammatory response and cause an imbalance between the procoagulant and anticoagulant homeostatic mechanisms. Multiple pathogenic mechanisms are involved, including endothelial dysfunction, increased von Willebrand factor, Toll receptor activation, and tissue factor pathway activation. D-dimer levels greater than 1000 ng / mL are associated with an 18-fold increased risk of mortality. In this context, many patients may require prophylaxis or antithrombotic treatment with low molecular weight heparins. Currently, there is no validated scheme on the dose and timing of the use of antithrombotic drugs. The study aims to identify the effect of two anticoagulant strategies (prophylactic and therapeutic) on the progression to ventilatory support or death in patients with COVID-19 infection who require hospital care.

Fresh-Frozen Plasma Infusions to Reduce Risk of Bleeding Related to Invasive Procedures

Blood Coagulation Disorders

This study will compare patients with mild to moderate prolongation of the INR test who receive FFP infusions prior to invasive hepatobiliary procedures for bleeding complications to patients who do not receive FFP infusions. Bleeding complications will be defined as meeting one or more of the following: Intrahepatic hematoma greater than 1 ml/kg of patient weight as seen on post-procedure ultrasound examination performed between 4 to 30 hours after the procedure. Greater than 1.6g/dL hemoglobin decline measured within 4 to 30 hours post-procedure compared with the pre-procedure value, in the absence of another identified bleeding source to account for the hemoglobin drop. Need for transfusion of packed red blood cells for procedure-related bleeding while in the study. The secondary endpoints of this study will be: 1) The need to perform subsequent procedures (angiography, embolization, additional imaging study including computerized tomography (CT) scan, surgery) to diagnose or to arrest procedure-related bleeding OR the need for subsequent medical therapies (FFP, coagulation factor concentrates, anti-fibrinolytics) to treat procedure-related bleeding between time of procedure and the end of patient's time in the study. If necessary, the relationship of procedure or therapy to procedure-related bleeding will be assessed by an adjudication panel; 2) The predictive value of INR; 3) The effect of study treatment on change in INR; 4) The cost of preventing one bleed; 5) The predictors of bleeding other than INR; 6) The number of transfusion-associated adverse events encountered to prevent one bleed; and 7) The effect of treatment on bleeding grade.
