Active clinical trials for "Hemorrhage"

The purpose of this study is to determine if closing the tonsil fossa after tonsillectomy leads to less pain and bleeding risk than leaving it open to heal by secondary intention.

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.

Objectives: Blood in stomach & oesophagus in patients with variceal bleeding often obscures the endoscopic view & makes endoscopic intervention difficult to perform. Erythromycin, a motilin agonist induces gastric emptying. The aim of this study was to assess the effect of Erythromycin on endoscopic visibility and its outcome.

This study will examine the combined effects of a continuous oral contraceptive (OC) regimen with supplemental frovatriptan therapy on headache severity and occurrence in subjects with documented Menstrually Associated Migraines (MAM). The subjects enrolling in the study will have cyclic menses either due to spontaneous ovulation or use of cyclic hormonal contraception (pill, patch, or ring). Enrolled subjects will start a continuous OC regimen following two baseline menstrual cycles. If breakthrough bleeding/spotting (BTB/BTS) occurs, the subject will institute a 4-day hormone-free interval (HFI). In an attempt to prevent/lessen the severity of headache during the HFI, subjects will be randomized to prophylactic administration of a triptan or placebo during this period. If no BTB/BTS occurs after 80 days of continuous pills, the subject will institute a 4-day HFI during which they will be randomized into triptan or placebo groups. The purpose of this research study is to examine the effects of continuous oral contraceptive pills and frovatriptan on headaches that occur around the time of your period. Many woman take continuous oral contraceptive pills (OC) and when OCs are stopped they may get headaches. This study will look if taking frovatriptan around the time of the period will affect the headache, and how it will be affected. Frovatriptan is an FDA approved drug for migraine headaches. This study is a prospective pilot trial.The study will last approximately 35-39 weeks.

The specific objective of this trial is to determine the lowest dose and dose frequency possible with the best pharmacokinetic and safety profile and it's ability to remove a blood clot from the ventricular system.

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).

The main objective of this study is to determine the efficacy of early administration of Sanvar® in combination with endoscopic treatment for the control of acute variceal bleeding.

Endoscopic treatment of bleeding peptic ulcers is effective to prevent rebleeding. Adjuvant medical treatment to increase gastric pH may further decrease rebleeding. Recent studies on potent acid suppression by proton pump inhibitors (PPI) demonstrated the efficacy in preventing rebleeding. Lau demonstrated that high dose intravenous infusion of omeprazole decreased rebleeding in peptic ulcers with stigmata of recent hemorrhage. There is little data regarding the effect of pantoprazole on bleeding peptic ulcers. Furthermore, the optimal dose of PPI is unknown. Few studies have included measurement of gastric pH in addition to clinical outcome. This study compares the effect of two doses of intravenous pantoprazole with no acid suppression in bleeding peptic ulcers after endoscopic therapy. In addition to the usual clinical endpoints, gastric pH is monitored to study the relation of pH elevation and the clinical outcome.

To investigate if self-inserted vaginal misoprostol prior to outpatient hysteroscopy will lead to satisfactory cervical ripening, compared to placebo.

The aim of this clinical research project is to evaluate the use of the recombinant human activated factor VII (rhFVIIa), given as a salvage therapy, in women with a dramatic postpartum hemorrhage still ongoing after all the currently available medical and surgical treatments. We are going to compare its early use, before elective surgery or arterial embolization, to its late use, after embolization or surgery, before salvage hysterectomy.
