Active clinical trials for "Hemorrhage"

The natural history of cirrhosis has a symptomatic and asymptomatic stage. The symptoms include the development of ascites, hepatic encephalopathy, or variceal bleeding. The development of portal hypertension represents a critical transition point in the natural history of cirrhosis, contributing to, or directly responsible for all of these events. It is defined by an increase in intrahepatic vascular resistance to portal venous inflow, with the subsequent development of collateral vessels, such as esophageal or gastric varices. As portal pressures rise over time, however, the resulting increase in variceal size and wall tension translates into an increasing likelihood of rupture and bleeding, leading to death in about 30% of patients. Over the last twenty years, data have emerged regarding the role of tumor necrosis factor (TNFα) in portal hypertension from animal models as well as in vitro experiments. Portal hypertension is a condition characterized by vasodilatation and a hyperdynamic circulation, driven by relative overproduction of nitric oxide23. In animal trials using inhibitors of TNF it has been shown to decrease the development of the hyperdynamic circulatory state and portal pressure.24-25 Based on these data, investigators have examined the role of TNF inhibition with thalidomide. Significant improvement in blocking the development of the hyperdynamic circulation and portal pressures was demonstrated.26 Human trials have also show the efficacy of thalidomide in reducing portal pressures. In that these trials have shown promising results further investigation is

The Purpose of this study is compare the efficacy of intravitreal triamcinolone in clearing recurrent post-vitrectomy diabetic hemorrhage with conventional treatment, air-fluid exchange.

Strict glycemic control improves mortality and morbidity of patients admitted to the postoperative intensive care unit (ICU). The investigators would like to know if this therapy could improve the long term neurologic and cognitive outcomes of patients treated for acute subarachnoid hemorrhage with either a surgical or intravascular approach.

The use of prophylactic antibiotics in cirrhotics with gastrointestinal bleeding has been a routine clinical practice . It is still unknown whether use of short term vasoconstrictors and antibiotics could have superior acute hemostatic rate. Thus, the investigators conducted a trial to compare the effectiveness between participants receiving terlipressin and ceftriaxone 5 days and terlipressin and ceftriaxone 2 days after endoscopic therapy in cirrhotic patients presenting with acute gastro-esophageal variceal hemorrhage..

Treatment of hemorrhoidal disease includes a conservative approach (dietary and behavioral measures, venotropic and topical medication), office-based treatments and surgery. Rubber banding is currently considered the instrumental method of choice in the treatment of hemorrhoidal disease grades I to III (Goligher's classification). However, its use in patients with bleeding disorders is not recommended. Sclerotherapy can be performed in these patients since the hemorrhagic risk is very low. The most commonly used agent for sclerotherapy is liquid polidocanol. Polidocanol foam seems to be more effective than the liquid formulation and is safe in the treatment of hemorrhoidal disease even in patients with coagulation disorders. This study is aimed to evaluate the efficacy and safety of polidocanol foam sclerotherapy in the treatment of hemorrhoidal disease grades I to III in patients with bleeding disorders.

The Efficacy and safety of Preoperative Intravenous Tranexamic acid versus Sublingual misoprostol in reducing blood loss during and after Elective Cesarean section among high risk pregnant cases.

The purpose of this single center, randomized, control, open-labeled study is to evaluate the effect and safety of RCA versus no anticoagulation for CRRT in hyperlactatemia patients with increased bleeding risk.

The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.

Spontaneous cerebral hemorrhage is one of the main causes of death and disability all over the world, accounting for 20%-30% of all cerebrovascular diseases. Minimally invasive surgery of cerebral hemorrhage, especially puncture aspiration, can improve early and long-term neurological recovery in patients with cerebral hemorrhage. Until now, no standardized practice for minimally invasive surgery of spontaneous cerebral hemorrhage has been established. Hematoma puncture and drainage based on CT scans without precise localization and personalized approach design, which may lead to poor efficacy and high risk of complications. Our hospital has much experience in treating cerebral hemorrhage with stereotactic puncture and aspiration. So we conduct a prospective multicenter randomized controlled clinical trial to determine the therapeutic effects of puncture aspiration plus thrombolysis treatment for the perioperative and long-term recovery of patients with small to moderate hematoma in deep basal ganglia via computerized precision coordinates and personalized approach design.

We prepare this study to compare the efficacy of intermittent intravenous PPI infusion (relatively low dose PPI therapy) than continous PPI infusion method. Our hypothesis is that intermittent (40mg as a bolus injection daily for 72 hours) PPI therapy is not inferior to conventional high dose therapy.
