Active clinical trials for "Hemorrhage"

Previous studies in both the cardiovascular and orthopedic study have shown tranexamic acid (TXA) reduces blood loss and post-operative blood transfusion rate largely without major complications . In addition, many meta-analyses have confirmed these results . However, there is little information about comparison among the different routes of TXA administration in TKA. Therefore, this study has been designed to determine which administration route of TXA is more effective and safety.

Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality worldwide and is caused most commonly by poor uterine muscle (myometrium) tone after delivery. The first line agent used in the prevention and treatment of PPH is oxytocin. Women who require augmentation of labor with intravenous oxytocin because of inadequate labor progression have been shown to be at increased risk of PPH. Typically, for augmentation of labor, oxytocin is used as a continuous infusion, with no consensus on the initial dose, its increments or maximal limit. High concentration continuous oxytocin infusions are not without theirs risks, which include hyperstimulation, fetal distress, as well as uterine rupture. Studies have shown the clinical benefits of pulsatile oxytocin delivery for labor induction and augmentation with regards to requirement of less total oxytocin, similar uterine contractility and similar rates of caesarean delivery when used for labor induction and augmentation. However, the rate of PPH as a primary outcome measure has not been investigated. Therefore we currently do not know the effect of pulsatile oxytocin delivery on the rate of PPH. The investigators hypothesize that the effect of myometrial desensitization following pulsatile oxytocin exposure would be lower when compared to continuous oxytocin exposure. These results will help in establishing whether myometrial contractility and sensitivity to oxytocin can be better preserved by delivery of pulsatile oxytocin, rather than continuous oxytocin for labor induction and augmentation, and thereby result in less PPH.

The purpose of this study is to determine whether 40 mg octreotide long-acting release intramuscular every 28 days is effective in the treatment of patients with refractory anemia due to gastrointestinal angiodysplasias. We hypothesize that octreotide is effective in reducing the transfusion requirements (consisting of red blood cell transfusions and intravenous iron infusions) of patients with angiodysplasia-related anemia.

The aim is to compare the safety of using transfemoral and transradial approach in patient undergoing carotid arteries stenting.

This study is a randomized, double-blind, placebo controlled trial that will enroll 250 women (125 per study arm). The objective of the study is to determine the efficacy and tolerability of oral tranexamic acid when used as an adjunct to misoprostol for treatment of postpartum hemorrhage (PPH). Women will be diagnosed with postpartum hemorrhage if blood loss reaches 700ml in the calibrated receptacle. If diagnosed with postpartum hemorrhage , the woman will be randomized to receive either tranexamic acid or placebo, both in tablet form. All participants will receive 800 mcg sublingual misoprostol (4 tablets 200mcg each). The investigators hypothesize that tranexamic acid (in tablet form) as an adjunct to misoprostol will be more effective than misoprostol alone in stopping postpartum bleeding without recourse to further treatment in significantly more women.

The trial objective is to demonstrate the safety of idarucizumab, as assessed by the occurence of patients with drug related adverse events (including immune reactions) and all-cause mortality in paediatric venous thromboembolism patients treated with dabigatran in ongoing clinical trials who require emergency surgery/urgent procedures or patients who have life-threatening or uncontrolled bleeding which requires urgent intervention, when rapid reversal of the anticoagulant effect of dabigatran is needed.

The specific aims are to determine if more women using Etonogestrel (ENG) contraceptive implants who report a bleeding-spotting episode of at least seven days will stop bleeding within 3 days of beginning a 14-day course of combined oral hormonal steroids, as compared to women receiving 14 days of placebo.

There is a wide variability of options for treatment of chronic radiation proctitis. However, studies are still limited, usually case reports from a single center and few are comparative studies between methods. Therefore, the choice of treatment is determined by availability and local expertise for each method. The variability of treatment options range from anti-inflammatory medical treatment, sucralfate, short chain fatty acids, antioxidants and hyperbaric oxygen to such endoscopic and surgical treatments. Surgery is usually the last therapeutic option due to the high morbidity and mortalityassociated. Various endoscopic treatment modalities have been reported. Formalin topic is effective in up to 48% of patients with chronic radiation proctitis. The endoscopic treatment with argon plasma (APC) is low cost, easy to apply and transportation, safe and effective in the treatment of rectal bleeding in patients with chronic radiation proctitis. Currently, the APC is the preferred endoscopic modality. Most studies on the use of APC in radiation proctitis showed benefit. The APC controls the mild to moderate rectal bleeding in 80% to 90% of cases and improves symptoms of urgency, diarrhea and tenesmus in 60% to 75% of cases.

This is a randomized, placebo-controlled, single-center clinical trial investigating the effectiveness of administrating intravenous Cerebrolysin™ (EVER NEURO Pharma, Austria), a preparation of low-molecular weight neurotrophic peptides and free amino acids, in improving the functional outcome of patients suffering from aneurysmal subarachnoid haemorrhage ( SAH). Cerebrolysin™ is a porcine-derived intravenous formulation composed of multiple lipid-soluble active agents that can cross the blood-brain barrier. It is a registered medication in several countries indicated for stroke and Alzheimer's disease. It contains several low molecular weight neuropeptides and free amino acids that possess neuroprotective and neurotrophic properties. It has been proven to arrest or mitigate several crucial steps along the ischemic cascade in preclinical studies. Cerebrolysin™ has been extensively investigated in patients suffering from Alzheimer's disease, brain trauma and ischemic stroke with promising clinical results. It's use in SAH patients has never been investigated and it is believed that it may play a role in improving clinical outcomes. Consecutive patients aged 18 to 70 years-old diagnosed to have spontaneous subarachnoid hemorrhage secondary to a ruptured intracranial aneurysm will be randomly allocated into one of two study arms: (1) to receive intravenous Cerebrolysin™ in additional to standard of care (intervention group) or (2) to receive usual standard of care alone (control group). Permuted-block randomization will be carried out once the eligibility criteria have been fulfilled using a computer system with an allocation list of random order. Instructions on study arm allocation will be contained in sealed envelopes labeled with sequential study numbers. Patients presenting beyond 96 hours after onset of symptoms or if recruitment and randomization cannot be performed within this time period will be excluded. The reason being that post-SAH arterial vasospasm and delayed cerebral ischemia usually occurs four days after aneurysm rupture and lasts for two weeks i.e. 14 days. Should this complication arise before Cerebrolysin™ is administered there would be significant confounding of trial outcome measures . The timing of intervention is in keeping with several landmark clinical studies that have dealt with neuroprotective agents in subarachnoid hemorrhage. Patients in the intervention group will receive in a daily total dose of 30ml of intravenous Cerebrolysin™. The study medication will be administered in three separate 10ml doses (every eight hours) diluted in 0.9% NaCl saline to a total volume of 100 ml as an intravenous infusion over a time period of 15 minutes. An identical amount of 0.9% sodium chloride (NaCl) saline (100 ml) will be used as placebo for patients allocated to the control study group. The total duration of study medication or placebo administration will be 14 days. Cerebrolysin™ is a clear yellow solution. Since it is susceptible to photo-degeneration the preparation after dilution with 0.9% NaCl saline requires masking with a opaque plastic wrap as well as special photo-protective infusion sets. The dilution of the Cerebrolysin™ solution will be performed by ward nursing staff . Subjects in both trial groups will receive identically wrapped preparations so that both the functional outcomes assessor and patient are blind to the study arm allocation. In addition to general demographic data, clinical data including the admission Glasgow Coma Score, severity grading of SAH, hospital stay as well as the extended Glasgow Outcome Score and modified Rankin Score upon discharge, at three months and six months will be prospectively collected. The functional outcomes assessor will be an occupational therapist unaware of the subject's trial group allocation. Hypothesis: compared to patients receiving standard care for the management of aneurysmal subarachnoid hemorrhage alone (control), the additional administration of intravenous Cerebrolysin™ (intervention) within the acute phase of stroke is safe and improves functional outcome at six months after stroke.

When having certain types of outpatient surgery inside the uterine cavity some women experience heavy bleeding. The only method presently available for controlling such bleeding, short of removing the uterus, involves the placement of a balloon pressure device inside the uterine cavity. The pressure along with the patient's own natural clotting ability will generally stop the bleeding. However, this treatment usually requires at least a 24 hour stay in the hospital. The investigators are researching the use of a compound (FloSeal) already approved for use in other areas of the human body, as a method of controlling bleeding. The use of FloSeal in the uterine cavity has not yet been tested and therefore is not yet an FDA approved indication for its safe use to control bleeding from the uterine cavity. In this study, The investigators want to find out what effect(s) FloSeal has on the uterine cavity. Twenty individuals will be included in this study at Northwest Hospital Center. All twenty individuals will be treated in the same fashion except ten of the participants will randomly be assigned to receive FloSeal and ten will not. Study participants are individuals currently scheduled to have a hysterectomy procedure, which involves surgically removing the uterus from the body for a previously determined standard of care treatment for a non- cancerous medical problem. Before performing the hysterectomy and evaluating the effects of FloSeal upon the tissues within the uterine cavity the following will be done. Once under anesthesia the uterine cavity will be subjected to a curettage (sharp scrapping) to produce a minor amount of bleeding from the lining of the uterus. Ten of the 20 study participants, randomly chosen, will then have FloSeal placed into their uterine cavity. The study participants will not know whether they received FloSeal or not. A balloon pressure device will then be placed into the uterine cavity of all 20 individuals and left in place for 5 minutes. After the allotted time, the balloon device will be removed. The hysterectomy will then be completed appropriately using standard methods and techniques. The uterus, once removed will be evaluated pathologically to determine the effects of the FloSeal upon the tissues of the cavity in those so treated and compared to the same analysis in those individuals who did not receive FloSeal. The pathologist will not know which patients received or did not receive FloSeal. This use of FloSeal is not currently an FDA approved use of the compound. The goal of this study is to obtain FDA approval for use in this situation.
