Filter by:The purpose of this study was to evaluate that the tranexamic acid (TXA)Intravenous and oral, is equivalent oxytocin (OXY),intramuscularly, in reducing the blood loss in post partum period (mL) in patients at the end of pregnancy ( 37-42 w ) at low risk of post partum hemorrhage (PPH). The PPH means a blood loss equal to or greater than 500 ml after a vaginal delivery ( the bleeding is defined severe if it exceeds 1000 mL). PPH is called "primary" when blood loss arose within 24 hours after birth. This is a open-trial randomized, longitudinal, controlled that including 486 subjects .
The goal of this study will be to determine whether PCC confers any benefits over FFP in traumatic and spontaneous intracranial hemorrhage with respect to multiple factors including time to correction, absolute international normalized ratio correction amount, cost, need for surgical intervention, and radiographic bleed expansion through a prospective, randomized control trial.
The purpose of this study will be to evaluate a standardized, evidence-based protocol versus a conventional approach for the dosing of oxytocin in vaginal delivery.
Type A Thawed Plasma (TP) will be compared in polytrauma patients who receive only Normal Saline (NS) (standard of care) before arrival at the hospital. The purpose of this study is to determine if prehospital administration of thawed plasma can reduce mortality of patients who have lost a large amount of blood due to their injuries, compared to those receiving standard of care.
Background: Repeated episodes of bleeding from gastrointestinal vascular malformations refractory to endoscopic or surgical therapy often pose a major therapeutic challenge. Methods: The investigators will perform a randomized, double blind, placebo controlled study of thalidomide as a retreatment therapy for recurrent gastrointestinal bleeding due to vascular malformation. Patients with failure of first course treatment of thalidomide will be randomly grouped, prescribed a second four-month course regimen of 25 mg of thalidomide or placebo orally four times daily. All patients will be monitored for at least one year. The primary end point is defined as the patients whose rebleeds decrease from baseline by ≥ 50% at 12 months and the cessation of bleeding. Rebleeding is defined based on a positive fecal occult blood test (FOBT) (monoclonal colloidal gold color technology) at any visit after treatment. Secondary outcomes include the participants dependent on blood transfusions and changes from baseline in transfused packed red cell units, bleeding episodes, and hemoglobin levels at 12 months. Statistical significance is defined at P < 0.05.
Subarachnoid Hemorrhage (SAH) can occur commonly in the setting of trauma or brain aneurysm. SAH accounts for 10% of all the strokes. Aneurysmal SAH accounts for 80 % of cases of non-traumatic cases of SAH, 6-8% of all strokes and 22-25% of all cerebrovascular deaths. Mortality can be 50% in the first few years of aneurysmal SAH rupture, 15% are severely disabled post SAH and only 20-35% having a moderate to good recovery it has gained lot of attention and pre-clinical and clinical trials of various agents have been tried to prevent poor outcome. The United States epidemiology data reveals the fact that 1% to 5% of adults have unruptured brain aneurysm and 30,000 people suffer from aneurysm rupture annually translating to brain aneurysm rupture every 18 minutes. Vasospasm is the most common SAH complication post 24 hours. It is the segmental or diffuse narrowing of the vessels especially the large vessels. Fifty percent of those patients who develop clinical vasospasm, progress to infarction and 15-20% will advance to disabling stroke or die of cerebral ischemia. The present treatment modalities are insufficient to prevent vasospasm. So, we need new treatment modalities to decrease the mortality and morbidity in SAH patients. The investigators hypothesize that Acetazolamide administration can prevent development of vasospasm after aneurysmal SAH.
The purpose of the study is to determine whether noninvasive hemoglobin monitoring is sensitive and accurate enough to detect a significant downward trend in hemoglobin in patients at risk for significant bleeding. If this can be shown, it has the potential to spare patients multiple invasive blood draws as well as allow for earlier detection of significant blood loss and therefore positively impact on patient morbidity and mortality. Additionally, it may represent significant financial cost savings in that it may allow for patients to be monitored in a non-intensive care unit setting. This will be an observational study. The continuous hemoglobin monitor will be connected to the patient and hemoglobin measurement data will be collected. Routine laboratory hemoglobin monitoring will occur concurrently at a pre-specified frequency as well as at the physician's discretion based on usual clinical information. The physician will be blinded to the continuous hemoglobin monitoring readings and therefore patient care will not be affected by the use of the monitor. Once the study has ended, the data will then be analyzed to assess for correlation between continuous hemoglobin monitoring readings and laboratory hemoglobin measurement.
The purpose of this study is to determine the safety and efficacy of a drug minocycline in improving outcomes at 3 months after rupture of an aneurysm in the head.
The lack of a precise diagnostic technique for cerebral vasospasm associated with traumatic brain injury (TBI) limits the ability to detect and treat this phenomenon. Surveillance Transcranial Doppler ultrasonography (TCD) is the main medical instrument that is utilized to monitor radiographic vasospasm following TBI, yet has its drawbacks such as inaccuracy, highly operator dependent and more. HS-1000 device, an investigational vasospasm detection device, has the potential to safely diagnose and assess vasospasm with minimal discomfort to patients, allowing a new modality for vasospasm measurement tool. We aim to evaluate the correlation between the collected and analyzed data from the HS-1000 device and the clinical findings from the TCD tests post-subarachnoid hemorrhage (SAH) patients.
This is a randomized, double-blind, placebo-controlled, single-dose study investigating the safety and efficacy of NA-1 in patients with subarachnoid hemorrhage (SAH) undergoing endovascular repair of ruptured intracranial aneurysms. Up to 300 male and female patients with SAH undergoing endovascular repair of a ruptured intracranial aneurysm will be dosed with 2.60 mg/kg of NA-1 or placebo as a 10 minute intravenous infusion after completion of the endovascular procedure on Day 1 of the study period. Subjects will undergo interim procedures at Day 2-4, Day 30-45, and end-of-study procedures on Day 90.
