Active clinical trials for "Blood Coagulation Disorders"

This study evaluates the hemostatic changes defined as hemostasis reserve capacity (HRC) in the first perioperative 48 hours of bloodless liver transplanted patients.

The trial is conducted in North America. The aim of the trial is to assess the safety of turoctocog alfa under conditions of routine clinical care in patients with haemophilia A in Mexico

Dexmedetomidine may alter whole blood coagulation. However, little is known about the dose-response relationships according to the blood concentration of dexmedetomidine. The investigators have therefore performed the present study to measure the effect of dexmedetomidine on the coagulation pathway according to the drug concentration level using a rotational thromboelastometry test.

Psychological stress (PSS) is one of the most common problems among healthcare providers during COVID-19 pandemic. PSS influences the homeostatic equilibrium of the body, involving activation of the sympathetic nervous system and hypothalamus pituitary adrenal (HPA) axis. Copeptin; C-terminal portion of Vasopressin (AVP) precursor is stable. Nevertheless, Evidence about influence of PSS on copeptin levels is lacking. The reason we are doing this research is to determine the level of psychological stress among healthcare providers exposed to at the time of work in intensive care unit (ICU) during COVID-19 pandemic; They will be appraised every assembly for psychological stress level; before start of duty shifts (first time), one week after start (second time) and two weeks after departure from shift duties in ICU (third time) for assessment of psychological stress level and stress hormones.

This study was conducted in Africa, Europe, the Middle-East and South America. The primary objective of this registry was to observe the use of single dose and multi-dose use of activated recombinant human factor VII and to compare short-term outcomes, including effectiveness, safety, quality of life and treatment satisfaction with the approved treatments.

This NON INTERVENTIONAL OBSERVATIONAL STUDY is conducted in Europe. The primary aim is to observe the haemostatic efficacy of NovoSeven® treatment during routine practice in German clinics. The observational study observes patients with congenital haemophilia with inhibitors to coagulation factors VIII or IX, acquired haemophilia, congenital FVII deficiency, or Glanzmann's thrombasthenia who have received at least one dose of NovoSeven® for treatment of a bleeding episode or for the prevention of a bleeding when undergoing surgery or an invasive procedure.

This study is conducted in Europe. The purpose of this retrospective study is to collect additional safety information of patients with haemophilia and inhibitors who are treated with rFVIIa.

Cytoreductive surgery (CRC) with intraperitoneal hyperthermal chemotherapy (HIPEC) has been shown to improve survival in selected patients with peritoneal carcinomatosis. 51% of patients are transfused due to the high intraoperative blood loss caused by surgery and the appearance of a perioperative coagulopathy attributed to the loss of proteins into the peritoneal cavity, the high fluid turnover and possibly the action of hyperthermic chemotherapy. So far, the haemostatic changes described consist of a decrease in the levels of antithrombin III and the platelet count, as well as in alterations of the usual coagulation tests. Conventional coagulation tests analyze only the plasmatic phase of coagulation while viscoelastic tests, such as rotational thromboelastometry (ROTEM), reproduce the global coagulation process much more faithfully, keeping good correlation with perioperative bleeding. Objetive: The platelet, coagulation, von Willebrand and Factor XIII levels and function have not been consistently investigate in pre-established (fix) time periods in patients undergoing elective CRC with hyperthermia. This prospective observational study aimed at investigating the variations of the values of estándar coagulation test, ROTEM parameters, platelet function assay (PFA-100), von Willebrand and Factor XIII at baseline (before surgery) and after 4h and 48 after surgery in 40 patients undergoing CRC. A control group (N=40 blood donors) will be also obtained by baseline comparasion and to obtain local reference ranges.

This cross-sectional pilot study will examine the blood clotting patterns in children with chronic kidney disease stages 3, 4, and 5. A total of 30 participants will be enrolled with 10 participants for each stage of chronic kidney disease. Blood specimens will be collected from each participant during a routine clinic visit, and will then be processed to evaluate blood clotting characteristics according to thrombelastography and more conventional clotting tests.

The investigators try to improve the screening of bleeding disorders in children by identifying symptoms, laboratory abnormalities and clinical scores discriminating patients congenital bleeding disorders in order to create a simple screening algorithm applicable in pediatrics, aiming for use in pre-anesthetic consultation and in consultation by pediatricians and general practitioners.
