Active clinical trials for "Hemorrhage"

This study is a prospective evaluation of patients with occult (hidden) GI bleeding without iron deficiency. Such patients usually undergo a diagnostic colonoscopy as a standard of care. The study is aimed to determine any UGI-source of occult bleeding and to correlate UGI symptoms with findings. Therefore, EGD is being offered to such patients as part of research. We proposed to enroll 200 consecutive patients referred to our GI-unit for expedited diagnostic colonoscopy for positive FOBT.

This study will determine if rhubarb will reduced the incidence of pneumonia and improved recovery from an acute cerebral hemorrhage. The study is designed to look at both infection rate and overall recovery and recovery of motor function, for example muscle strength and coordination.

The purpose of this study is to evaluate the superiority of effect of the modified micro-invasive aspiration and drainage and conservative medical therapy in the treatment of ICH spontaneously hypertensive scientifically.

The purpose of this trial is to determine the optimal dose of rt-PA in the treatment of intracerebral hemorrhage (ICH) using a combination of minimally invasive surgery and clot lysis with rt-PA。

BACKGROUND: The investigators developed a fiber-optic-guided endotracheal suction catheter (visual sputum suctioning system or VSSS), which the investigators previously tested in vitro and animals. It integrates a 0.9-mm micro-imaging fiber into a 3.7-mm double-lumen catheter. PURPOSE: The purpose of this study was to investigate the safety and efficacy of sputum suctioning system in mechanical ventilated patients in respiratory intensive care unit (RICU). The investigators compare the weight of secretions collected, vital signs, and tracheal wall injury between two groups of patients randomized to have VSSS combined with closed system suction (CSC) suction and patients having CSC suction alone. HYPOTHESIS: The investigators theorized that the VSSS collected more sputum and caused less change of vital signs than conventional CSC.

The purpose of this study is to determine the effect of a contraceptive vaginal ring on inhibition of ovulation, endometrial changes and bleeding patterns in normal cycling women.

All women presenting to the gynaecology outpatient clinic with heavy menstrual bleeding (HMB) in the absence of recognizable pelvic pathology, as determined by one or all of a normal pelvic ultrasound, hysteroscopy and / or endometrial biopsy, refractory to medical therapy that persists despite treatment with recommended pharmacological agents(1,2), who have no desire to preserve their fertility and are willing to have an endometrial ablation will be invited to participate. Eligible women with HMB will undergo radiofrequency G4 endometrial ablation in either an inpatient or outpatient setting according to their preference. Outcomes will be assessed by administering postal questionnaires to measure menstrual bleeding symptoms including rates of amenorrhoea, dysmenorrhoea and life quality at baseline and at 6, and 12 months after ablative treatment. After the main study, there will be an additional evaluation of the long-term effects of outpatient ablative treatments of the endometrium by postal survey at 5 years.

This community-based cluster Randomised Control Trial will assess the feasibility, cost, risks and benefits of use of oral Misoprostol and parenteral Oxytocin in Uniject® as prophylaxis for postpartum hemorrhage (PPH) in community settings. The study will be conducted in Jamnagar district in Gujarat state in India. The hypothesis is that a program to deliver oral misoprostol and one to deliver oxytocin via Uniject® will both be effective in preventing PPH when introduced in community-based settings.

Intraoperative administration of tranexamic acid (TXA,T) reduces significantly blood loss and blood transfusion requirements during spinal posterior fusion in adolescents with scoliosis. TXA acts mainly by inhibit the plasminogen activator. Desmopressin (DDAVP ,D) can inhibit the fibrinolytic activity by inducing the release of von Willebrand factor from the endothelial cells. But at the same time, it releases tissue-type plasminogen activator (t-PA), which may cripple its hemostatic effect. The investigators supposed that if the investigators combine TXA with DDAVP in scoliosis correction surgery, the blood loss and the transfusion need would be reduced significantly.

Primary Objective: To investigate the effectiveness of intravitreal applications of 0.5 mg Lucentis (ranibizumab) in patients with vitreous hemorrhage due to proliferative diabetic retinopathy. The primary endpoint for the study will be the mean change in best-corrected visual acuity (BCVA) from baseline to the mean level at Month 3. Secondary Objectives: To assess any differences in mean change in BCVA over time; To assess differences in vitreous transparency (amount of hemorrhage) with fundus angiography exam; To assess any differences in retinopathy severity level according to the Early Treatment Diabetic Retinopathy Study; To correlate the visual outcomes with serum glucose levels.
