Early VItrectomy in DENse Spontaneous Vitreous HEmorrhage
Spontaneous Vitreous HemorrhageRetinal Break1 moreThe aim of the protocol is to compare the ocular outcomes after spontaneous vitreous hemorrhage treated with an early vitrectomy versus ultrasound monitoring with late vitrectomy. The hypothesis is that an early vitrectomy could decrease the rate of retinal detachment occurring after a spontaneous vitreous hemorrhage.
OTSC vs. Angiographic Embolization in Patients With Refractory Non-variceal Upper Gastrointestinal...
Upper Gastrointestinal BleedingIn the management of patients with acute upper non-variceal upper gastrointestinal bleeding, further bleeding is the most important adverse factor predictive of mortality. In the United Kingdom Audit on acute upper gastrointestinal bleeding, clinical evidence of further bleeding was reported in 13% of patients following the first endoscopy and 27% of them died. The use of OTSC has emerged as an alternative before angiographic embolization(TAE) which is often considered most definitive. We propose to define the algorithm in the management of patients with refractory bleeding from their peptic ulcers or other non variceal causes. We hypothesize that endoscopic use of OTSC compares favourably with TAE and both lead to similar outcomes. An equivalence of the two modalities may mean that endoscopic application of OTSC should be attempted before TAE as often we need to document further bleeds with endoscopy and a second treatment should be instituted at the same time.
Tranexamic Acid as an Intervention in Abruptio Placenta
Vaginal BleedingProlonged PregnancyAbruptio placenta is one of the common causes of antepartum haemorrhage which is more common in the second half of pregnancy and causes a high maternal and neonatal morbidity and mortality
Standard Endoscopic Hemostasis Versus OVESCO Severe Non-variceal UGI Hemorrhage
Upper Gastrointestinal HemorrhageThe primary specific aim is to perform a randomized controlled trial (RCT) to compare 30 day rebleed rates and other clinical outcomes of patients with severe, non-variceal upper GI hemorrhage (NVUGIH) - ulcers and Dieulafoy's lesions who are randomized as initial treatment with the new large over-the-scope-clip device for endoscopic hemostasis versus standard endoscopic hemostasis.
Recombinant Factor VIIa (rFVIIa) for Hemorrhagic Stroke Trial
Intracerebral HemorrhageThe objective of the rFVIIa for Acute Hemorrhagic Stroke Administered at Earliest Time (FASTEST) Trial is to establish the first treatment for acute spontaneous intracerebral hemorrhage (ICH) within a time window and subgroup of patients that is most likely to benefit. The central hypothesis is that rFVIIa, administered within 120 minutes from stroke onset with an identified subgroup of patients most likely to benefit, will improve outcomes at 180 days as measured by the Modified Rankin Score (mRS) and decrease ongoing bleeding as compared to standard therapy.
The Effect of Placental Cord Drainage on Postpartum Blood Loss
Postpartum HemorrhageTo determine if placental cord drainage decreases the blood loss after spontaneous vaginal delivery
Argipressin's Influence on Blood Loss During Hepatic Resection
Colon Cancer Liver MetastasisInflammatory Response1 moreInfusion of Argipressin during hepatic resection surgery may reduce blood loss. It may also reduce transfusion requirements, and mitigate the perioperative inflammatory response compared to placebo. Subjects will be randomized to infusion of Argipressin or placebo during surgery. Blood loss, transfusion requirements, surgical data including length of stay in hsopital, inflammatory markers and markers of renal- intestinal- and cardiac injury will be assessed.
Bipolar Hemostatic Forceps Versus Standard Therapy in Acute Non-variceal Upper GI Bleeding
Gastrointestinal HemorrhageBipolar hemostatic forceps will be tested against standard therapy in active, non-variceal, upper gastrointestinal bleeding by a prospective, randomized trial
Application of tPA in Suprachoroidal and Subretinal Hemorrhage
Ocular TraumaSevere ocular rupture may be accompanied by suprachoroidal hemorrhage, or subretinal hemorrhage, or with suprachoroidal hemorrhage and subretinal hemorrhage. The suprachoroidal hemorrhage needs to be drained as soon as possible. In the process of waiting for the spontaneous liquefaction of hemorrhage, uncontrollable elevated intraocular pressure may occur, resulting in optic nerve injury, optic nerve atrophy, and visual loss. Tissue plasminogen activator can promote the liquefaction of blood clots. Studies have found that local application of tissue plasminogen activator in the suprachoroidal space can promote the liquefaction of the hemorrhage. Local application of tissue fibrinogen activator under the retina can promote the liquefaction of subretinal hemorrhage.
Zotarolimus vs Sirolimus Eluting Stent in High Bleeding Risk
High Bleeding RiskCoronary Artery Disease1 moreRandomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (TLF) at 12 months in high bleeding risk patients who underwent elective coronary percutaneous intervention with a zotarolimus eluting stent versus a sirolimus eluting stent and short Dual Antiplatelet Therapy (DAPT).
