Filter by:To demonstrate that the combined used of oxytocin and misoprostol prevent from post partum haemorrhage better than oxytocin alone, following vaginal birth at 36 to 42 weeks.
Haemorrhoidal artery ligation operation (HALO) is an operation that ties off vessels to piles. This study examines whether the ultrasound (doppler) is necessary to guide this tying off or not.
The purpose of this study is to find out what effects, good and bad, the medication Albumin has on subjects who have experienced a type of stroke known as an intracerebral hemorrhage (ICH). An ICH is when spontaneous bleeding into the brain occurs due to fragile blood vessels. This research is being done because currently there is no effective treatment for ICH. However, study investigators believe that Albumin, the medication being tested in this study, is safe and may help improve patient recovery from ICH over time. Subjects will be enrolled in the study for a total of 90 days. Following enrollment, subjects will be randomized to receive 3 daily injections of either Albumin or Placebo (liquid with no drug), and will receive 3 brain MRI scans (with and without contrast), as described below. All subjects will be monitored continuously through 96 hours after enrollment (5 days) in the Georgetown ICU. Blood tests and clinical evaluations of neurological status, consisting of questions about subjects' functional abilities and medical history, will occur in the Georgetown ICU once every 24 hours through post-enrollment Day 5. Additionally, subjects will receive daily chest x-rays, and daily EKGs (exams that monitor how your heart is doing by placing electrodes, or small monitors, on your skin in specific locations). Similar clinical evaluations will occur at Day 30 and Day 90. Should subjects be discharged at these time points, day 30 assessments will occur over the phone, and day 90 assessments will occur in-person at Georgetown University Medical Center.
This study is designed to assess how rapidly and how safely Clevidipine can be used to control high Blood Pressure in patients with subarachnoid hemorrhage which is a type of brain bleed that happens because of a weak balloon like structure in one of the brain vessels. Control of blood pressure is of high value in preventing this balloon that ruptured and bled from rebleeding. The ultimate cure would be to shut down the aneurysm by a surgical procedure. Clevidipine is a drug that can lower blood pressure and it is given through the vein as a continuous infusion. It is a very short acting drug which is important in controlling labile blood pressure condition with rapid changes between up and down. This trial will test for its rapid actions and check for any side effects and possibly any other potential benefit.
The aim of this study is to demonstrate that clazosentan, administered as a continuous intravenous infusion at either 5 mg/h or 15 mg/h until Day 14 post aneurysmal subarachnoid hemorrhage (aSAH), reduces the incidence of cerebral vasospasm-related morbidity and all-cause mortality within 6 weeks post-aSAH treated by endovascular coiling. The primary endpoint of the study is the occurrence of cerebral vasospasm-related morbidity, and mortality of all-causes within 6 weeks post-aSAH, defined by at least one of the following: 1. Death (all causes). 2. New cerebral infarct(s) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 3. Delayed ischemic neurological deficit (DIND) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 4. Administration of a valid rescue therapy in the presence of confirmed cerebral vasospasm on angiography (DSA or CTA). An independent Critical Events Committee (CEC) will adjudicate whether or not patients meet the primary endpoint and its individual morbidity components.
To evaluate the feasibility of performing a cervical sympathetic block in patients with severe cerebral vasospasm involving the anterior cerebral circulation following aneurysmal SAH.
Context: A major lack of organ donors is a serious public health problem. It determines a prolonged delay before a transplant can be performed and thus a significant number of deaths of patients waiting for transplantation. The aim of this project is to reduce the delay of the diagnosis of brain death, and also to improve its diagnosis in the Intensive Care Unit. The diagnosis of brain death is strictly defined by the law and relies either on two consecutive flat electroencephalograms recorded at an interval of four hours, or on the lack of cerebral circulation during a brain angiography performed after suspecting brain death on the clinical exam. However, in usual practice, it is difficult to have all the needed clinical arguments, and their interpretation can be difficult in the pathological context. This may participate in the delay and the lack of patients potentially donors. Pre-study: In a pilot study, fifty subjects with severe cerebral lesions, had a continuous ECG recording. The investigators could find that a decrease in autonomic nervous system activity, as measured through the ECG, was correlated to the transition to brain death assessed by cerebral angiography. The loss of cardiac variability was always observed between two cerebral angiographies, one before and the second after brain death. This study allowed the investigators to calculate the threshold values of sympathetic and parasympathetic activities to confirm brain death.
The purpose of this project is to describe the pathophysiology of thrombocytopenia and bleeding in patients with Wiskott-Aldrich Syndrome (WAS) and determine the response to thrombopoietic agents in vitro and in vivo.
Some patients undergoing cardiac surgery develop excessive postoperative bleeding. Cardiopulmonary bypass causes platelet dysfunction. Several studies have documented the ability of desmopressin to reduce hemorrhage in a variety of congenital and acquired platelet disorders. In this study the investigators will investigate wether desmopressin reduces postoperative microvascular bleeding. The investigators will investigate wether desmopressin reduces platelet activation as measured by plasma concentration of neutrophil activating peptid 2 and by flow cytometry. The primary endpoint of the study will, however, be total postoperative bleeding and need for transfusions of blood components after surgery. The need for transfusions will be registered during the whole hospital stay. Patient with excessive postoperative bleeding (more than 250 ml for one hour, or more than 150ml for two hours during the first four hours) will be randomized into two groups and given either desmopressin or placebo (0,9% sodium chloride) as an intravenous infusion. Blood samples for plasma concentration measurements will be drawn before infusion of desmopressin/placebo, immediately after the infusion and 20 hours postoperatively. Postoperative bleeding will be registered for 16 hours. The need for any transfusions of blood products will be registered for the whole hospital stay.
The purpose of this study is to test the feasibility of a trial on induced hypertension to improve neurological outcome in patients with subarachnoid haemorrhage that developed the serious complication "delayed cerebral ischemia", and to assess whether induced hypertension results in improved cerebral blood flow (CBF) as measured by means of perfusion-CT.
