Filter by:Extensive research has shown that the big event that leads to the initiation of vasospasm is the release of oxyhemoglobin (blood breakdown product).Depletion of NO synthase (19,20,21) was also noted after SAH.CSF is produced from choroid plexus in the ventricle. If the SAH is too dense, the blood in the subarachnoid space will not easy to be washed out.
The purpose of this study is to determine the effect of pre- and intra-operative bevacizumab injection on postoperative vitreous hemorrhage after diabetic vitrectomy.
This is a prospective, randomized trial to see in patients undergoing coronary artery bypass grafting and endoscopically-harvested greater saphenous vein, if using FloSeal Matrix in the endoscopically-harvested saphenous vein wound bed decreases bleeding and complications.
This multicentre open-label randomized parallel-group trial aims to evaluate the association intermittent pneumatic compression + elastick stockings versus elasting stockings alone on symptomatic or asymptomatic venous thromboembolism incidence, evaluated systematically at day 6 (+/-2days), in patients hospitalized in intensive care units and with high bleeding risk.
In unselected cirrhotic patients with acute portal hypertension-related bleeding to compare the effectiveness in control of bleeding, mortality rate, duration of life, quality of life, and economic costs of two widely used treatment measures: (1) emergency transjugular intrahepatic portal-systemic shunt (TIPS), and (2) emergency portacaval shunt.
Intraoperative blood loss is a major concern during hepatic resection, as it has been shown to adversely affect patients' perioperative outcome. Reduction of central venous pressure during parenchymal transection has been shown to effectively lower liver hemorrhage. While CVP reduction is mainly achieved via fluid restriction and diuretics, dehydration may impair organ function. Moreover, it may lead to hemodynamic instability, particularly in case of severe bleeding. For this reason the technique of infrahepatic inferior vena cava clamping has been suggested which is able to lower CVP without the need for fluid restriction. In the present study the two strategies to reduce CVP and by this intraoperative bleeding, namely fluid restriction and inferior vena cava clamping are compared with intraoperative blood loss as primary endpoint.
The main purposes of this study are to compare clinical outcomes of two groups of patients with similar medical conditions (one with non-variceal upper gastrointestinal (UGI) lesions such as ulcers and another group with varices or portal hypertensive lesions) who are treated either with current standard visually guided endoscopic treatment according to stigmata of hemorrhage or with endoscopic Doppler endoscopic ultrasound probe (DEP) monitoring of blood flow in the lesion.
Intracranial bleeding from ruptured blood vessels (called a subarachnoid haemorrhage -SAH) affects 7000 patients each year in the UK and is a source of considerable death and disability, even in young adults. Recent observations indicate that these bleeds can cause reduced cerebral blood flow which leads to a bad outcome. High rates of death and disability occur, and are particularly prevalent when low cerebral blood flow results in stroke. Prevention of cerebral artery spasm and improvement in blood vessel reflexes are the target of modern therapy. Candidate drugs include statins which have an impeccable safety record and multiple potential beneficial actions (improve cerebral blood flow, reduce inflammatory processes, reduce adverse blood coagulation) following SAH. The investigators plan to use a statin, Simvastatin (40 mg) to improve cerebral blood flow and reduce inflammation. We have already completed a phase 11 study (n=80) which demonstrated potential benefits for acute statin therapy following SAH, and the investigators now wish to conduct a multi-centre phase 111 study to explore any potential clinical benefits in a larger population (n=1600). The purpose is to see whether the positive effects of statins seen in our phase II study translate into clinical benefits - both short term (e.g. reduced need for intensive care) and long term (outcome and wellbeing at 6 months).
Several recent clinical trials have documented that early aggressive resuscitation approached guided by defined hemodynamic variables using thoughtful protocols may improve outcome. The concept underscored by this newer trial was that appropriate resuscitation prevents subsequent tissue injury even if overt shock is present, if the resuscitation is carried out early enough.
Study Objective: To analyze if statins are effective in ameliorating perihematomal edema evolution thereby reducing mortality and improving functional outcomes following spontaneous intracerebral hemorrhage (ICH).
