Active clinical trials for "Hemorrhage"

The study aims at comparison between the effect of preoperative misoprostol and bilateral uterine artery ligation regarding their effect to decrease blood loss in transabdominal myomectomy.

The Postpartum Haemorrhage (PPH) Butterfly is a simple, low-cost device which has been developed as a treatment method for PPH. It will be used to stop the bleeding through compression of the uterus of women having a PPH. It will be markedly easier to undertake than traditional bimanual compression, whilst also being significantly more acceptable to women themselves. Use of the PPH Butterfly will provide an alternative management option for PPH and in some cases should avoid the need for women to have to go to theatre for treatment. This research will allow the investigators to determine if they have the optimum size and shape of the device, that it will operate as intended when compressing the uterus, and to gauge its acceptability to participants and users. In phase I the investigators will recruit "healthy volunteers" i.e. women who have delivered their baby vaginally following Induction of labour (IOL) however these women will not be experiencing a PPH. The device is to be assessed purely on size, usability and acceptability not for diagnosis or as a treatment method. Following the delivery participants will be invited to have the PPH Butterfly inserted vaginally for an average of 2 minutes. It is through this that the investigators will assess the suitability of the device in its current design, when it is in practice. The clinician who operates the device will complete a Likert scale questionnaire along with some open questions following each administration. Participants will also answer a short questionnaire. .

This study aims to use validated tools as well as new technology to examine changes in bleeding patterns among women who are initiating the copper T380A IUD.

The prevalence of portal vein thrombosis (PVT) in patients with liver cirrhosis is 5-20%. Current evidence regarding the effect of portal vein thrombosis on the prognosis of cirrhotic patients remains under debate. Considering that PVT potentially elevates the portal pressure and thereby increase the risk of variceal bleeding, we focus on the patients with high-risk varices and variceal bleeding as the study population. Thus, the main goals are to analyze the effect of PVT on the incidence of first variceal bleeding in patients without any prior bleeding history but with high-risk varices, the incidence of recurrent variceal bleeding in patients with a history of variceal bleeding, and the treatment failure rate of variceal bleeding in patients with acute variceal bleeding. Certainly, the survival is also observed in all patients.

One of the well-known of complications post colonic polypectomy is bleeding usually occuring in the 2-week period following the procedure. Patients treated with oral anticoagulation (e.g. Warfarin) are a special and challenging patient group due to the need on the one hand to prevent thromboembolic events, and on the second hand to minimize the risk of post-polypectomy bleeding. Current practice guidelines recommend holding Warfarin treatment while bridging with LMW Heparin while resuming Warfarin treatment following the procedure. This practice was found to be associated with a much higher rate of bleeding compared with continuing Warfarin in a recent prospective trial in pacemaker transplanted patients. The fact that most post-polypectomy bleeding occurs within the 2-week period further questions the current practice of periprocedural bridging therapy. the investigators therefore hypothesize that patients with continuous Warfarin treatment may have similar post-polypectomy bleeding rates compared to patients receiving bridging therapy with LMW Heparin. This is a multicenter single-blinded prospective randomized trial comparing small post-polypectomy (polyps<10mm) bleeding rates between two groups of patients: Continuous therapy with Warfarin, vs. LMW Heparin therapy while withholding Warfarin therapy (current practice).

Subarachnoid hemorrhage (SAH) occurs after rupture of cerebral aneurysms. Treatment of SAH focuses on avoiding medical complications including cerebral vasospasm, which may result in limited circulation to the brain. Cerebral vasospasm, or thinning of the arteries of the brain, is a feared complication that could potentially cause stroke and worst outcomes after SAH. Hypertonic saline (HTS) is a compound that may be used to prevent vasospasm following SAH by enhancing the circulation in the brain. This study will evaluate if a protocol of volume expansion with HTS is safe and effective in patients with subarachnoid hemorrhage for the prevention of cerebral vasospasm.

The true incidence and risks of intracranial hemorrhage (ICH) in patients on various antithrombotic treatments remain unknown. Here a nationwide study is conducted to investigate the risk for and incidence rates of ICH in users and non-users of various oral antithrombotic drugs in Norway between 2008 through 2014. Hopefully, this study will contribute to a more responsible prescription pattern of antithrombotic medications.

The objective of this study is to investigate whether topical application of tranexamic acid into the uterine cavity and the surgical site intra-operatively can reduce blood loss and provide better surgical haemostasis in parturients with moderate to high risk for bleeding undergoing caesarean deliveries.

Rapid infusion of blood is needed occasionally for control massive bleeding. For rapid infusion, external pressure can be used. The investigators will study correlation between external pressure and hemolysis and deformability of red blood cell.

The purpose of this research study is to determine if the diameter and flow of the superior mesenteric artery in patients with aneurysmal subarachnoid hemorrhage undergoing hypertensive therapy for cerebral artery vasospasm are effected enough to justify withholding enteral nutrition.
