Active clinical trials for "Hemorrhage"

Primary objective: Evaluation of capsule endoscopy in the emergency setting of severe GI-Bleeding.

Non-traumatic intracerebral hemorrhage (ICH) affects approximately 100,000 Americans yearly. Up to 30-50% of ICH is fatal, and those patients who survive are often left with significant neurologic dysfunction. In the past, medical management (e.g., control of hypertension, reversal of antiplatelet or anticoagulants) had been the most effective treatment for these patients, given the morbidity and mortality associated with open surgical treatment for evacuation of ICH. However, recent trials have demonstrated that minimally invasive stereotactic neurosurgical procedures to evacuate ICH are safe and result in improved outcomes for these patients. Initial attempts to evaluate the efficacy of surgical evacuation of ICH found no significant difference between medical management and standard craniotomy for surgical evacuation. Indeed, open surgery was often discouraged for these patients due to the significant morbidity and mortality associated with the surgical procedure itself. However, research has demonstrated that minimally invasive, image guided stereotactic frame-based and frameless methods are effective and safe for the placement of catheters for clot aspiration and fibrinolytic therapy of ICH in the basal ganglia and other deep seated regions. Larger randomized controlled trials have demonstrated that these minimally invasive approaches also offer clinical benefit for these patients.

This is a multicenter, cluster randomized controlled trial to assess the effects of an optimized intraoperative fluid and blood management strategy on postoperative complications.

This trial is to determine the effect of Tranexamic Acid (TXA) on blood loss during endoscopic pituitary surgery. The hypothesis of this study is that TXA will reduce blood loss during surgery compared to a placebo. To answer this hypothesis, the investigators are conducting a randomized controlled trial in which half of participants will receive TXA and half will receive placebo (saline) in a double blind fashion.

This study investigates the effect of tranexamic acid, a medication that helps reduce bleeding, in patients undergoing surgeries around their eyes.

To determine the predictive factors of endometrial ablation failure in the management of uterine bleeding.

Background: Despite the capability of emergency surgery to reduce the mortality of severe spontaneous intracranial hemorrhage (SSICH) patients, the effect and safety of surgical treatment for severe spontaneous intracranial hemorrhage (SSICH) patients receiving long-term oral antiplatelet treatment (LOAPT) remains unclear. In consideration of this, the cohort study is aimed at figuring out the effect and safety of emergency surgery for SSICH patients on LOAPT. Methods: As a multicenter and prospective cohort study, it will be conducted across 7 representative clinical centers. Starting in September 2019, the observation is scheduled to be completed by December 2022, with a total of 450 SSICH patients recruited. The information on clinical, radiological, and laboratory practices will be recorded objectively. All of the patients will be monitored until death or 6 months after the occurrence of primary hemorrhage. Study Design: In this study, two comparative cohorts and an observational cohort will be set up. The primary outcome is the effect of emergency surgery, which is subject to assessment using the total mortality and comparison in the survival rate of SSICH patients on LOAPT between surgical treatment and conservative treatment. The second outcome is the safety of surgery, with the postoperative hemorrhagic complication which is compared between the operated SSICH patients on and not on LOAPT. Based on the observation of the characteristics and outcome of SSICH patients on LOAPT, the ischemic events after discontinuing LOAPT will be further addressed, and the coagulation function assessment system for operated SSICH patients on LOAPT will be established. Objective: In this study, investigators will estimate the effect and safety of emergency surgery for SSICH patients on LOAPT, which will provide an evidence for management in the future.

In this study, we aimed to investigate the effectiveness of ppi use in upper gastrointestinal bleeding in patients over the age of 18 who underwent endoscopy on mortality, length of hospital stay, rebleeding, and cost. The European Society of Gastrointestinal Endoscopy 2021 recommends the use of preendoscopic ppi in patients with nonvariceal upper gastrointestinal bleeding as it reduces the need for endoscopic treatment. This recommendation is recommended by the British Institute for Health and Care Excellence not to use proton pump inhibitors. Likewise, the 2021 American Gastroenterology Association did not make a recommendation for its use because the benefit of using preendoscopic ppi is uncertain. This has led to confusion about the efficacy of ppi and has questioned the necessity of routinely given high-dose ppi therapy. In this study, we aim to reveal the effectiveness of the treatment by comparing the patients who were given and not given ppi. Our research is a retrospective cohort study. Patients over the age of 18 who applied to the emergency department and had a preliminary diagnosis of upper gastrointestinal bleeding and underwent endoscopy will be included in the study. Patients who underwent endoscopy and were given ppi and those who were not will be compared. In upper gastrointestinal bleeding, patients with a Glasgow Blatchford score of 2 and above are taken to endoscopy. Therefore, patients over the age of 18 who underwent endoscopy will be included in the study.

Patients who were using anticoagulant or antiaggregant medications for any reason and underwent transurethral resection of bladder tumor (TUR-BT) or transurethral resection of the prostate (TURP) or open prostatectomy (OP) due to BPH will be compared with those who were not using anticoagulant or antiplatelet medication. The rates of postoperative clot retention, presence of hematuria, reoperation due to hematuria, blood transfusion and re-admissions due to hematuria in the first postoperative month will be compared.

The purpose of this implementation science study is to generate evidence that informs the successful uptake and adoption of the Ellavi UBT within Ghana's PPH management programs. The investigators aim to improve the likelihood that the Ellavi UBT will be integrated into the health care system by obtaining critical feedback from stakeholders and health care providers on the barriers and facilitators towards its successful adoption and roll out. The research will be done in three purposively selected facilities near Accra Ghana: Tema General Hospital, Ridge Hospital, and Kasoa Polyclinic. This study uses a nonexperimental design to collect data on implementation (e.g. # staff trained, usability, user confidence, acceptability, feasibility). The study team will train all obstetric healthcare staff (i.e. obstetricians, midwives, medical officers, clinical officers) involved in PPH management at the 3 participating healthcare facilities on the Ellavi UBT. The investigators will gather feedback from the obstetric healthcare workers (post-training and post-PPH) to understand the barriers to and facilitators of use in order to evaluate acceptability and feasibility among facilities providing different levels of care (level 4, level 5 (county), level 6 (tertiary)). This process will help to generate training and facility level recommendations for improved uptake and integration into the local maternal care package. Case report forms and semi-quantitative surveys will be completed by obstetrical care providers to evaluate the primary outcomes of acceptability and feasibility by measuring: context of use, accuracy of use, perceptions of the device, user confidence, acceptability, usability, facilitators of use, barriers to use, use-patterns, and insights into training effectiveness. The secondary outcomes will include financial data to determine the cost of introducing the Ellavi UBT into the Kenyan PPH management protocols and the health system. The study will not involve the storage of biological samples. There is not a direct benefit of the study to the individual participants. All study participants will sign consent forms.
