Active clinical trials for "Hemorrhage"

To determine whether HMG-CoA reductase inhibitor simvastatin prevents or ameliorates subarachnoid hemorrhage-induced delayed vasospasm and its ischemic consequences.

The purpose of this study is to determine the effect of pre- and intra-operative bevacizumab injection on postoperative vitreous hemorrhage after diabetic vitrectomy.

To identify the best approach for mitral valve replacement to decrease risk of bleeding and restrict blood transfusion and its complication.

Moderate-severe intraventricular hemorrhage (Grades II-IV, msIVH) is a significant neurological complication among extremely low gestational age neonates (ELGANs, <27+6 weeks) and is associated with long-term neurodisabilities. In Canada, msIVH affects ~25-30% of the 1300 ELGANs born annually, with little change in incidence over last decade. Typically, it occurs between days 2-7 of age, providing a finite window of opportunity. Instituting therapies at the population level, however, exposes many low-risk infants to side effects, adversely affecting risk-benefit profile and requiring large sample sizes in trials. A targeted preventative approach, though ideal, is currently challenged by our inability to reliably identify at-risk ELGANs early after birth. Near-infrared spectroscopy (NIRS) has emerged as a promising non-invasive bedside neuromonitoring tool. Pilot studies using NIRS, including ours, found lower cerebral saturations (CrSO2) and greater periods of altered cerebral autoregulation in infants who later developed msIVH. However, a systematic planned investigation is needed to establish the predictive characteristics of NIRS-derived markers, using clinically translatable methods (cumulative burden over time-period vs. single time-point values) and identify their relative performance at different time-points during transition. Further, incorporating echocardiographic (ECHO) hemodynamic markers, known to be associated with msIVH, may allow for the establishment of robust multi-model prediction models and the gain of mechanistic hemodynamic insights to inform future management. Hence, our objective is to investigate the utility of multi-modal assessment using NIRS and ECHO for early identification of ELGANs at risk of msIVH, and generate clinically applicable predictive model(s).

Tranexamic acid is a medication used to treat or prevent excessive blood loss during surgery. Previous studies have shown tranexamic acid (TXA) reduces blood loss and post-operative blood transfusion rate without significant complications. In addition, many meta-analyses have confirmed these results. This study also aims to determine how safe and effective tranexamic acid treatment is for different patients undergoing primary total knee arthroplasty.

Continuous renal replacement therapy is widely used in intensive care medicine, which is known as an alternative therapy to save injured kidney . Anticoagulation is an important part of this therapy. An insufficient anticoagulation would cause a poor curative effect of CRRT. Hemorrhage，heparin-induced thrombocytopenia (HIT), citrate accumulation, acidosis ad filter extra-cost usually happened on anticoagulation during CRRT. Therefore a new effective anticoagulation of CRRT needs to be carried out. Nafamostat Mesylate (NM) is a new anticoagulant. This serine protease inhibitor with broad spectrum can inhibit kinds of enzymes on the process of coagulation. NM is mainly rapidly decomposed in the liver and also removed by dialysis or filtration. The elimination half life of is only 8 minutes. If NM is applied as a regional anticoagulant, approximate 40% NM is removed by dialysis and / or convection in cardiopulmonary bypass circuit, and then rapidly degraded by esterase in liver and blood, which ensures security in patients with bleeding tendency. Based on the information above, the investigators designed an observational clinical study aimed to testify that NM would have equivalent anticoagulant results compared with those traditional ways and might even have a better effect than traditional anticoagulant therapy.The study team has investigated the current situation of CRRT in Shaanxi province in China through a cross-sectional survey last year. The survey involved 74 hospitals in Shaanxi province and the results basically illustrated a real status of CRRT. These scientific results helped investigators to design this multi-center, parallel, controlled, non intervention study and real world study.

This is an interventional, non-randomized, controlled, pilot study that explores a new approach to treat, Abnormal uterine bleeding-menometrorrhagia in women, being candidates for hysterectomy, based on tea infusion consumption of a mixture of two plants.

Functional endoscopic sinus surgery (FESS) is well established for treatment of chronic rhinosinusitis and nasal polyps. Masking of the surgical field can lead to severe complication as tissue injury, increase post-operative adhesions and scarring and even severe orbital and brain injury In the current study we will investigate the effect of nasal desmopressin versus oral bisoprolol for controlling bleeding and improving surgical field clarity during functional endoscopic sinus surgery

To evaluate the efficacy and safety of oral Nimodipine and IV milrinone combination therapy for management of cerebral spasm after aneurysmal subarachnoid hemorrhage.

Rationale: Intrasaccular neck occlusion devices have been used for unruptured aneurysm without safety concerns and good occlusion rates. In the setting of a subarachnoid hemorrhage, they could improve the rate of complete occlusion without safety concerns. Aim: To explore the safety and efficacy of intrasaccular neck occlusion devices in patients with acute subarachnoid hemorrhage caused by a ruptured saccular aneurysm by a one arm prospective registry. Study outcome: The primary outcomes is the rate of complete occlusion (Raymond-Roy I) and rebleeding at one year follow-up. The primary safety outcome is rate of rebleeding during the admission.
