Association Between Haptoglobin Genotype and Brain Swelling
Intracerebral HemorrhageIntracerebral hemorrhage is bleeding into the brain and is a major cause of stroke and other complications. Brain injury from intracerebral hemorrhage occurs in two phases. The early phase involves the mechanical compression of brain tissue by the expanding hematoma. In a later phase, brain swelling develops causing further compression that may lead to brain herniation and death. This study investigates the neuroprotective role of haptoglobin, in minimizing the development of brain swelling following intracerebral hemorrhage.
Bleeding Prediction in Patients Following Cardiac Surgery Using Whole Blood Aggregometry and Thromboelastometry...
Heart DiseaseCoronary Artery Disease2 moreUse of whole blood impedance aggregometry and rotational thromboelastometry can reveal useful data about platelet function and viscoelastic properties of blood clot in patients undergoing cardiac surgery. The purpose of this study is to clarify whether it is possible to predict patients on excessive risk of perioperative bleeding using whole blood impedance aggregometry and rotational thromoelastometry. Antiplatelet therapy is the cornerstone in treatment of patients with coronary artery disease. Another research goal is to determine the degree of response to antiplatelet therapy before and after surgery and to investigate whether patients by level of response to antiplatelet therapy before surgery have a higher risk of perioperative bleeding.
Ventriculostomy in Subarachnoid Hemorrhage (SAH): Intracranial Pressure (ICP) Open or Not?
Subarachnoid HemorrhageThe purpose of this study is to explore two currently accepted methods of intracranial pressure (ICP) management through cerebral spinal fluid (CRF) drainage for patients diagnosed with subarachnoid hemorrhage (SAH). This is a randomized observational study of two physician-prescribed approaches to managing ICP monitoring and CSF drainage for SAH patients. The study will enroll only those patients who have ICP monitoring. Because this is an observational study, there are no physical risks to the patient, the only risk is loss of confidentiality.
Effectiveness, Safety and Feasibility of Auxiliary Nurse Midwives' (ANM) Use of Oxytocin in Uniject™...
Postpartum HemorrhageThis cluster randomized community-based trial is designed to test the hypothesis that the intramuscular administration of 10 IU of oxytocin in Uniject™ during the third stage of labor by an Auxiliary Nurse Midwife (ANM) at births occurring in homes, Sub-Centers and Primary Health Centers in Bagalkot, India will reduce the risk of postpartum hemorrhage by 44% (from 9% to 5%) relative to home births attended by the same type of provider who does not provide the intervention drug. The study will also document correct use of oxytocin in Uniject, adverse maternal and fetal events associated with inappropriate use and a number of indicators reflecting the programmatic feasibility of implementing this intervention.
Low vs. Very Low Dose of Prophylactic Tranexamic Acid for Bleeding Reduction During Rhinoplasty...
Bleeding ReductionThe purpose of this study is to determine whether very low dose of preoperative tranexamic acid (5mg/kg) is as effective as low dose (10mg/kg) for intraoperational bleeding reduction in patients undergoing elective rhinoplasty surgery.
Misoprostol as First Aid Measure to Address Excessive Postpartum Bleeding
Postpartum HemorrhageThe overall study purpose is to evaluate the safety, feasibility and acceptability of advance distribution of misoprostol to be used as 'first aid treatment' administered by the woman herself or her family to help treat excessive bleeding in home births.
Effectiveness of Intravenous Tranexamic Acid in Reducing Blood Loss During and After Cesarean Section...
BleedingIn this study, the efficacy and safety of tranexamic acid in the reducing the blood loss during and after elective LSCS will be investigated.
Factor Replacement in Surgery
Bleeding in Cardiac SurgeryThis is a multicentre, randomized, active-control, pragmatic, Phase 2 pilot study in adult cardiac surgery patients. Two Canadian hospitals will participate, and it is estimated that the study will take approximately 9 months to complete. Approximately 120 bleeding adult cardiac surgical patients who require coagulation factor replacement during cardiac surgery will be included. Patients will be randomized to receive either PCC or FP when the blood bank receives the first order for coagulation factor replacement and deems it to be in accordance with accepted clinical standards. Patients will be treated according to their assigned group on the first and second times when coagulation factor replacement is ordered during the treatment period (24 hours after randomization). For any additional doses (i.e., the third dose and thereafter), patients in both groups will receive FP (in 1U increments at the discretion of the ordering physician). No other aspects of care will be modified. This pilot study aims to select a clinically relevant primary efficacy endpoint for a confirmative Phase 3 study, which will subsequently aim to determine if PCC is non-inferior or superior to FP in terms of effica-cy and safety in bleeding cardiac surgical patients. In the pilot study, safety outcomes will be measured for the first 28 days, which is the duration of participation of each patient in the trial.
Reversal of the Antithrombotic Action of New Oral Anticoagulants
ThrombosisAnticoagulant-induced Bleeding2 moreThe main goal of this study is to improve safety and efficiency of clinical practice with the new generation of oral anticoagulants. To determine the effect of new oral anticoagulants (dabigatran and rivaroxaban) on platelets and coagulation mechanisms under flow conditions. To evaluate the ability of the concentrates containing coagulation factors (PCCs and FVIIa) to reverse the effects induced by the new anticoagulants. These studies will be carried out ex vivo in blood samples obtained from healthy volunteers undergoing oral anticoagulant therapy at doses of proven efficacy and safety used in previous clinical trials.
Standard of Care Versus Hemopatch® During Liver Resection
Liver CancerHemorrhage Liver3 moreThis multicentre prospective and randomized study aims to compare the sealant effect after surgical liver resection of a new collagen - polyethylene glycol hemostatic / sealant patch (Hemopatch) vs standard of care.
