Active clinical trials for "Hemorrhage"

This study seeks to evaluate the efficacy, safety and tolerability of elagolix alone and in combination with estradiol/norethindrone acetate for the management of heavy menstrual bleeding associated with uterine fibroids in premenopausal women.

The purpose of this study is to assess the independent effects of both a 4-Factor prothrombin complex concentrate (PCC) - (Kcentra) and Tranexamic acid (TXA) on the bleeding parameters (bleeding duration and blood volume) following a punch biopsy, in addition to assessing their effects on the anticoagulant/pharmacodynamic (prothrombin time and endogenous thrombin potential) changes induced by rivaroxaban at steady state, to better understand their potential role in bleeding reversal.

The purpose of this study is to evaluate the safety and potential therapeutic benefit of use of clazosentan in reversing cerebral vasospasm (a narrowing of blood vessels in the brain due to the presence of blood in the space around the brain) in patients who have suffered a condition known as aneurysmal subarachnoid hemorrhage caused by bleeding onto the surface of the brain from a ruptured brain aneurysm

Various vasoactive drugs are recommended to use in combination with endoscopic variceal ligation (EVL) in treating acute esophageal variceal bleeding (EVB). The efficacy and drug choice of vasoactive agents under Taiwan's National Health Insurance program remain to be validated. The aim of this prospective cohort study was to assess the efficacy of somatostatin, compared with terlipressin in cirrhotic patients who have acute EVB and received EVL and the preference of vasoactive agents in real-world clinical practice. From April 2010 through April 2015, cirrhotic patients with significant upper gastrointestinal bleeding were screened. Eligible patients with acute EVB were non-randomly assigned to receive early administration of somatostatin (group S) or terlipressin (group T) infusion, followed by EVL. A decision to use vasoactive drugs depended on the physician's favorite. In group S, somatostatin by intravenous bolus (250 μg) followed by 250 μg/hour was continued for 3 days. In group T, terlipressin was started with 2mg bolus injection and followed by 1 mg infusion every 6 hours for 3 days.

Haemorrhagic strokes represent about 10-15 % of all strokes and 30,000 cases per year in France. The 30-day death rate ranges from 30 to 55% (50% of deaths occurring within 48 hours). Currently, no urgent medical or surgical treatment has been shown to improve functional or vital prognosis. Clinical epileptic seizures frequency in acute intracerebral haemorrhage has been estimated between 4% and 16% but the occurrence of subclinical epileptic seizures (detected on the electroencephalogram (EEG) only) could be much more frequent (28 % to 40 %). Some studies have suggested that early repeated epileptic seizures may be associated with a worse neurological prognosis. Repeated epileptic seizures occurring in the acute phase may increase brain oedema, worsen, hypoxia and may lead to cellular death in the injured brain tissue. Thus, prevention of early epileptic seizures may improve neurological outcome. However, the efficacy of a systematic prophylactic antiepileptic treatment on clinical and subclinical epileptic seizures has not been evaluated in the setting of intracerebral haemorrhage. The current European guidelines recommend the use of antiepileptic drugs only when epileptic seizures occur. Primary objective: PEACH is a randomized controlled trial aiming at evaluating the impact of systematic prophylactic antiepileptic treatment with levetiracetam versus placebo in acute supratentorial spontaneous intracerebral haemorrhage. The primary endpoint is the occurrence of at least one clinical or electrical epileptic seizure recorded on continuous 48h holter EEG. Secondary Objectives:This study also aims to assess: Ä The efficacy of prophylactic treatment with levetiracetam on the number of EEG seizures, on the total duration of epileptic seizures continuously recorded on EEG, on the occurrence of some paroxysmal EEG patterns, on the number of clinical seizures occurred during 72 hours of diagnosis, on the occurrence of early (day-0 to day-30 ) and late (from day-30 to 12 months) clinical seizures, on the functional prognosis at 3 , 6 and 12 months evaluated by the modified Rankin scale , on the cerebral oedema and mass effect evaluated by comparing the admission brain CT scan with the control CT scan performed at 72 hours, on the neurological status as assessed by the National Institute of Health Stroke Scale at 72 hours , 1 month and 3 months and on the quality of life measured by the Stroke impact Scale at 3, 6 and 12 months. Ä The frequency of side effects related to treatment with levetiracetam (anxiety and depression assessed by the Hospital Anxiety and Depression Scale at 1 and 3 months) Sample Size: 104 patients will be recruited over 2 years.

Gastrointestinal bleeding originating from the small bowel is difficult to diagnose and treat because the small bowel is difficult to see and reach. Balloon assisted enteroscopy (BAE) is a new enteroscopy methods that allow examination of the small bowel and allows for diagnosis and treatment of bleeding originating from this part of the intestine. Unfortunately, BAE is unsuccessful in identifying the cause of bleeding in 40-50% of patients. This may be due to limited visualization of the small bowel lining during conventional endoscopy. One way to improve visualization of the small bowel lining is by adding a transparent plastic cap to the end of the endoscope (camera), which allows the endoscope to see around sharp turned and behind folds in the small bowel. The investigators goal in this randomized controlled study is to see if adding a transparent cap to the end of the endoscope will help to identify and treat small bowel bleeding. The investigators will invite patients referred for BAE to participate in the study; the alternative to participating in the study is having standard BAE (without a cap). If patients choose to participate in the study they will be randomized to BAE with or without a cap on the end of the endoscope. Subjects time commitment will be limited to the consent process and pre-procedure paperwork at time of initial endoscopy and time required to complete telephone questionnaire at 12 months follow up.

Recently, there has been interest in applying tranexamic acid topically before the closure of surgical wounds in total hip replacement. It has the advantages of ease of application, maximum concentration at the site of bleeding, minimising its systematic absorption and, potentially , decline the risks for systematic side-effects 。

Total knee arthroplasty (TKA) is one of the most successful procedures in orthopaedic surgery. Nevertheless, significant postoperative blood loss and requirement of blood transfusion are still problematic. Total blood loss in TKA can be divided into visible and invisible blood loss. Visible blood loss (VBL) means blood loss from the surgical field and wound drainage while invisible blood loss (IBL) means residual blood in the knee, extravasation into the tissues and loss due to haemolysis. In usual practice, TKA is performed with a bloodless field using a tourniquet. Thus intraoperative blood loss can be negligible and postoperative drainage is only considered as VBLvisible. In terms of IBL, Sehat et al. found that TKA carried a substantial IBL. Their results shown the mean IBL was 765 ml or 49% of the mean total blood loss after TKA. Therefore, the true total blood loss was underestimated if not takes IBL into account. Modified Robert Jones bandage (MRJB) is a bulky compressive dressing that often used in orthopaedic practice. Various techniques of application have been proposed. From the previous study, MRJB could make and maintain the anterolateral muscle compartment pressure for at least 24 hours after TKA. Therefore, theoretically, this bandage can cause the tamponade effect that helps to reduce tissue edema and postoperative bleeding especially IBL after TKA. However this potential benefit of MRJB is unclear and the use of this bandage after TKA is still controversy in clinical practice.

Gastrointestinal vascular malformation (GIVM), which is an important cause of acute or chronic gastrointestinal bleeding, currently lacks of effective treatment. The investigators' previous study first confirmed thalidomide treatment of GIVM bleeding was safe and effective. This prospective multi-center randomized controlled clinical trial intends to investigate the efficacy of thalidomide to the recurrent small intestinal hemorrhage due to GIVM.
