Filter by:Endoscopic variceal ligation (EVL) and carvedilol have been documented to be effective in prophylaxis of the first bleeding. The efficacy & safety of combining EVL and carvedilol in prophylaxis of the first bleeding is still unknown. This study aims to investigate the value of combination therapy.
Florbetapir F 18 is an experimental radioactive drug that may allow doctors to image changes in the brain using a PET (Positron Emission Tomography) scanner. The purpose of this study is to evaluate the imaging characteristics of, Florbetapir F 18 (also known as 18F-AV-45) in patients who have previously undergone bleeding in their brains. Florbetapir F 18 binds to amyloid-ß peptide (Aß) that accumulates in the brains of patients with bleeding. These accumulations are called amyloid plaques and when extensive are labeled cerebral amyloid angiopathy (CAA). Florbetapir F 18 sticks to the amyloid plaques in the brain and emits a low level of gamma rays which can be detected by a PET camera. MRI detected microbleeds have been identified as markers of clinically silent hemorrhage from bleeding-prone vessels. Another imaging marker of vessel damage and risk of bleeding is the spot sign (SS). Finally, certain genetic signatures (ApoE genotype) have been shown to be associated with Aß deposition in the brain or predispose patients to higher risks of bleeding. This research study will explore the interactions of these factors and understand the physiology of intracerebral bleeding.
Postpartum hemorrhage is an important cause of maternal morbidity and mortality. In patients with severe preeclampsia there is an increased risk of postpartum hemorrhage but the hemodynamic changes associated with this pathology make the management of any kind of bleeding particularly troublesome. There are many pharmacological options, being oxytocin the first line of treatment. However there is no evidence about the safety and efficacy of carbetocin, an oxytocin agonist. The investigators aimed to compare oxytocin with carbetocin for the routine prevention of postpartum hemorrhage in patients with severe preeclampsia.
The objective of the study is to assess the safety and efficacy of the HemCon GuardaCareXR compared to standard bandaging in subjects with post partum hemorrhage as a result of cervical and vaginal lacerations. The primary endpoint will be a cessation of bleeding at 30 minutes after insertion of the dressing.
Sublingual misoprostol produces rapid peak concentration and is more effective than oral misoprostol for prevention of excessive postpartum bleeding. The study hypothesis was to test whether women receiving sublingual misoprostol for prevention of postpartum hemorrhage have 30 ml less average blood loss than women receiving oxytocin, the standard of care for prevention of postpartum hemorrhage. We conducted a Double blind randomized controlled trial of .652 consenting, eligible pregnant women admitted to the labor room of the teaching hospital at J N Medical College, Belgaum, India. Women participating in the study were assigned by computer generated randomization to receive the study medications and placebos within one minute after clamping and cutting the umbilical cord. We also looked at the drugs effects on postpartum blood loss at or above ≥500 ml (considered hemorrhage), and the percent of women experiencing more than a 10% decline in haemoglobin, and reported drug side effects.
The researcher's primary hypothesis is that VCE allows for safe outpatient management of ED patients with suspected upper GI hemorrhage. A prospective multicenter randomized control trial was designed to investigate the safety of this approach.
This study aims to assess postoperative blood loss and transfusion rates in total knee replacement after one-time administration of topical tranexamic acid.
The purpose of this study is to determine whether early use of transjugular intrahepatic portosystemic shunt (TIPS) with Polytetrafluoroethylene (PTFE) covered stents is able to prolong the survival in patients with advanced cirrhosis and acute variceal bleeding.
Severe maternal bleeding is a serious complication of birth and causes 125.000 deaths worldwide each year. The investigators aim to investigate if early treatment with fibrinogen concentrate versus saline can reduce the incidence of blood transfusion in women with postpartum haemorrhage. A low level of fibrinogen has been associated with increased blood loss and transfusion requirements in different clinical settings including obstetrical bleeding. Early up-front treatment with fibrinogen may reduce incidence of transfusion by securing optimal haemostatic capacity in women with postpartum haemorrhage. The investigators plan to enrol 245 patients on four hospitals in the Capital Region of Denmark during a two year period. As safety measure the investigators plan to use TEG®/Functional Fibrinogen/Rapid-TEG as haemostatic monitoring of all participants during the trial: Baseline test is taken at inclusion before administration of fibrinogen concentrate/placebo. Further tests are taken immediately after intervention, 4 hours and 24 hours after. Baseline test is blinded to the providers of treatment - the rest is clinically available.
This clinical trial will enroll 110 patients from approximately 15 Canadian stroke centres. Patients coming to the emergency department with bleeding in the brain not due to trauma or other known causes who can be treated within 6 hours of onset will undergo CT angiography using standard CT scanners ("CAT scan"). Those with a "spot sign", a type of marker on the CT scan that shows the brain is still bleeding, will be randomly assigned to a single injection of "factor 7"(a blood clotting drug used in hemophilia) or placebo (inactive saline); patients without a spot sign will not be treated. The researchers will look at how much bleeding happens after the treatments are administered, as well as clinical outcomes such as death and disability. The researchers think that factor 7 will cause the bleeding to stop faster and possibly decrease death and disability.
