Active clinical trials for "Hemorrhage"

Research has proven that large varices can be treated with beta-blockers (a type of anti-hypertensive medication) to reduce the pressure in the veins. The management of small varices is still uncertain. This study aims to discover if beta blockers can be used in this setting. We hypothesize that beta blockers will reduce the risk of bleeding from small varices from 20% to 10% over a period of 3 years, resulting in significant cost savings to the NHS from better patient outcomes.

This is a multicentre randomized placebo-controlled double-blinded phase IV study among 1000 women in Sweden and South Africa on the effect of oral tranexamic acid on PPH after vaginal delivery. The main purpose of the study is to evaluate the effect of orally administered tranexamic acid (TA) compared to placebo on rate of postpartum hemorrhage (PPH) after vaginal birth. Participants will be randomized to receive either 20 ml (2g) of the investigational medicinal product (TA100mg/ml) or 20ml of a placebo solution during labor. Our main endpoint, assessed at 24 hours after delivery is PPH defined as blood loss >=500ml and assessed both by weight and pre-postpartum hemoglobin (Hb) decrease >10 units difference in vaginal deliveries

The overall goal is to establish the safety and efficacy of colchicine in ICH patients for the prevention of major cardiovascular events and brain injury. Colchicine for the prevention of vascular events after an acute intracerebral hemorrhage (CoVasc-ICH) is a vanguard pilot trial designed to obtain the factual feasibility prerequisites essential for the planning, design, funding and execution of a subsequent phase III trial.

Multiple pregnancy is well defined to be associated with a greater risk of postpartum blood loss . Interventions to control PPH generally stepped from less to more invasive and including compression maneuvers , drugs , and further radical surgeries. Conservative management plans such as medications which cause the uterus to contract, external massage to the uterine body , and bimanual compression are overall used as 1st line interventions. PPH was defined as a cumulative blood loss of 1,000 mL or more, or blood loss that occurred within 24 hours of childbirth and was accompanied by indications or symptoms of hypervolemia. The most frequent cause of PPH, which accounted for roughly 80% of cases, is uterine atony (3). PPH is brought on by hyperexpansion, which impaired uterine myometrial contractility and caused uterine contraction fatigue , PPH were twice as high when pregnant with twins (4).The only effective surgical treatment for blood loss is a hysterectomy, but this is a risky procedure, especially for young women.(5) Due to this, a number of fertility-preserving surgical procedures have been developed, including the B-Lynch technique, internal iliac artery ligation, and uterine artery ligation (UAL) One of the most widely used surgical methods for preserving fertility is UAL. It is simple to carry out and works well to control PPH. Additionally, it permits patients to have more children in the future and is generally safe. Additionally, it has a success rate of above 90%. Concerns have been raised about its effect on women who want to become pregnant in the future regarding their ovarian reserve. The accepted practice of medicine worldwide is the prophylactic use of uterotonics. A synthetic oxytocin analogue with a lengthy half-life, carbetocin also stimulates uterine contractions . One benefit of carbetocin over oxytocin is that it is more heat-stable, which is of greater importance to low resource settings . Studies compare the effectiveness of carbetocin and oxytocin in preventing PPH and find that carbetocin is equally effective or even more effective.

Intracerebral hemorrhage (ICH) in patients with non-valvular atrial fibrillation (NVAF) poses a particular dilemma for thromboprophylaxis. Left atrial appendage occlusion (LAAO) is a non-pharmacological approach to prevent cardiac embolism in NVAF. The risk-benefit ratio of LAAO in patients with NVAF after ICH is unknown. The aim of STROKECLOSE is to assess the effect of LAAO to reduce the incidence stroke, bleeding and cardiovascular mortality in patients with NVAF and prior ICH.

This study aims to analyze the safety and effectiveness of the discontinuation/resumption protocol of factor Xa inhibitors before and after invasive procedures/surgeries in non-valvular atrial fibrillation patients who are at risk of minor bleeding in actual clinical settings

Tranexamic acid is an antifibrinolytics agent that has been widely used in the reduction of blood loss at surgeries. Oral clonidine is an alpha-2 adrenergic agonist that has been used in various surgeries including Caesarean section.

The objective of this study is to determine whether early video capsule endoscopy (VCE) immediately after a negative gastroscopy in the setting of suspected upper gastrointestinal bleeding (UGIB) improves patient outcomes as compared to the standard approach which typically involves performing colonoscopy prior to small bowel investigations. We aim to examine the differences in diagnostic yield, total number of procedures, length of hospitalization, mortality rates, and healthcare cost between the two groups.

Patients with a history of idiopathic gastroduodenal ulcer bleeding face an increased risk of recurrent ulcer gastrointestinal bleeding. Our ongoing clinical trial demonstrates a possible reduced risk of recurrent idiopathic gastroduodenal ulcer bleeding with proton pump inhibitor (PPI), yet there is a significant risk of recurrent ulcer bleeding as PPI may increase the risk of small bowel bleeding. Our preliminary data provide strong plausibility that a combination therapy of misoprostol (MISO) with a PPI reduces the recurrent ulcer bleeding as well as clinical gastrointestinal bleeding. The investigators are going to provide the definitive answer to this important clinical question through a randomised trial.

The SATURN trial aims to determine whether continuation vs. discontinuation of statin drugs after spontaneous lobar intracerebral hemorrhage (ICH) is the best strategy; and whether the decision to continue/discontinue statins should be influenced by an individual's Apolipoprotein-E (APOE) genotype. An MRI ancillary study (SATURN MRI), in a subset of SATURN participants , will evaluate the effects of continuation vs. discontinuation of statin drugs on hemorrhagic and ischemic MRI markers of cerebral small vessel disease, and whether the presence/burden of hemorrhagic markers (i.e. cerebral microbleeds and/or cortical superficial siderosis) on baseline MRI influences the risk of ICH recurrence on/off statin therapy.
