ROTEM Versus aPTT/PT in Pediatric Surgery

Coagulation Defect; Bleeding

Hemocoagulation management in perioperative bleeding is nowadays based on standard coagulation testing: activated partial thromboplastin time (aPTT), prothrombin time (PT), fibrinogen, D-dimers, platelets. An interest about viscoelastic coagulation testing methods is rising - use of rotational thromboelastometry (ROTEM) is mentioned in the newest European guidelines for hemostasis management. ROTEM has more advantages then standard tests. However, both tests have only grade 1C recommendation, and most of trials have been done on adults. The goal of the study is to compare a relationship between standard tests and ROTEM in pediatric patients in perioperative period to find out which test has better correlation with clinical status, to compare therapeutic strategies and time necessary for gain both of tests and to compare the difference in blood loss and blood products consumption in group treated by ROTEM versus standard tests. Reduced blood loss and amount of blood products transfusion is expected to be found in ROTEM group, representing lowering risk for the patient, all due to early evaluation of hemocoagulation and targeted therapy guided by ROTEM.

Lead-in Study to Collect Prospective Efficacy and Safety Data of Current FVIII Prophylaxis Replacement...

Blood Coagulation DisorderBlood Coagulation Disorders10 more

The aim of this prospective, observational study is to establish a dataset on the frequency of bleeding events, as well as other characteristics of bleeding events and FVIII infusions, in patients with clinically severe hemophilia A receiving prophylactic FVIII replacement therapy as standard of care. The data collected from this study may assist in providing baseline information for comparison to the Spark's investigational hemophilia A gene therapy in future Phase 3 studies.

A Prospective Study of Airless Tubing in an Inpatient Acute Hemodialysis Unit in Hospitalized Patients...

End Stage Renal Failure on DialysisComplication of Dialysis1 more

The introduction of unfractionated heparin (UFH), which prevents clotting of the extracorporal circuit, was one of the key advances that led to the rapid development and expansion of hemodialysis services. However, anticoagulation during hemodialysis of the patient at high risk for bleeding remains a frequently encountered problem in both inpatient and outpatient dialysis practice. Streamline bloodlines are designed to eliminate blood-air contact. This is thought to help reduce heparin use and decrease clotting rates. The goal of this study was to prospectively examine impact of the Streamline airless blood tubing set, in an inpatient setting, on dialysis circuit clotting rates, anticoagulation use, and dialysis efficiency.

Bedside Evaluation of Coagulation in Children With Congenital Heart Disease

Congenital Heart DefectBlood Coagulation Disorder

The purpose of this study is to assess coagulation and platelet function in children with congenital heart disease, measured with a bedside device (thromboelastometry and impedance aggregometry). The investigators also aim to determine if this device detect post-cardiopulmonary bypass clotting derangements and may help to manage bleeding in this population.

Anticoagulation and Antiplatelet Management During Perioperative Period

Anticoagulants and Bleeding Disorders

the investigators hypothesize that patients do not understand these therapies, and that they are poorly undertaken. In some cases, the anesthesiologist does not understand correctly the indication of the treatment due to lack of information and therefore does not know how to adapt it to the medical situation.

Clotting Parameters After Medical Abortion

Abortion EarlyAbortion8 more

Venous thromboembolism (VTE - blood clots that form in deep veins or in the lungs) has been identified as a leading cause of death in economically developed countries for pregnant and recently-pregnant women. There is evidence that clotting parameters can take up to 6 weeks to return to normal for women who have had term deliveries, however there is an absence of information on time taken for clotting parameters to normalise following abortion. As such, existing guidelines are based solely on expert opinion and recommend durations of VTE prevention from as short as 7 days, up to 6 weeks following abortion. All women are assessed for risk of VTE, but data are needed to inform an evidence-based approach to prevention of VTE in these women. The findings from this pilot study have the potential to inform clinical guidance and possibly a larger study subsequently.

Vascular Abnormalities and Bleeding Diathesis

Bleeding Diathesis

Inherited bleeding disorders (IBD) consist of a heterogeneous group of diseases including coagulation and/or platelets defects and more rarely vascular dysfunctions. A family of four patients suffering from unexplained excessive bleeding has been followed clinically in France for many years. Recently, whole exome sequencing (WES) of DNA allowed the identification of a heterozygous genetic variant which segregated to family members with bleeding diathesis. The aim of the study was to better characterize the phenotype by studying VWF and platelets in affected family members ultimately contributing to the pathogenesis of a bleeding diathesis.

Analysis of the Coagulopathy Developed by COVID-19 Infected Patients

SepsisBlood Coagulation Disorders3 more

Increased D-dimers at admission of COVID-19 infected patients entering hospital due to a severe disease is a risk factor for death. Understanding this acquired coagulopathy is a prerequisite before specific interventional studies. The study investigators aim to apply a normalized and automated thrombin generation test (TGT), developed for testing the thrombotic risk (triggered by 5 pM Tissue Factor, with a purified thrombomodulin (TM) challenge) and to study its association with survival.
