Filter by:Postpartum hemorrhage (PPH) is the leading cause of maternal mortality in low-income countries and the primary cause of nearly one quarter of all maternal deaths globally. Estimates of blood loss at delivery are notoriously inaccurate, with under-estimation more common than over-estimation. Traditionally, the surgeon performing the cesarean section would estimate the blood loss by visually assessing the blood collected in the surgical drape and counting the number of lap sponges used thru out the procedure. The investigators would like to study and validate an FDA approved device called the gauss Triton device used to estimate blood loss during scheduled cesarean sections.
The unbalanced estrogen with no progesterone will lead to endometrial thickening .This thickening result in endometrial hyperplasia & carcinoma and lead to irregular bleeding
Postpolypectomy bleeding is the most common major complication following a colonoscopic polypectomy procedure. The incidence rate ranging from 0.3 to 6.1%. Several preventive methods such as detachable snare and adrenaline injection have been proposed in the management of postpolypectomy bleeding in large colonic polyps. It has been demonstrated that administration of ascorbic acid (vitamin C) in abdominal surgeries could reduce the blood loss during the procedure, operation time and days of hospitalization. So the investigators designed a prospective, randomized study to compares the efficacy of vitamin C administration with application of prophylactic clip and detachable snare in the prevention of postpolypectomy bleeding in large polyps.
The study evaluates the safety and potential early signals of efficacy of allogeneic Thrombosomes in bleeding thrombocytopenic patients
The study is a prospective phase II randomised, double-blind, placebo-controlled investigator-driven trial in acute intracerebral haemorrhage patients. The study has 2 arms with 1:1 randomisation to either intravenous tranexamic acid or placebo and will test the hypothesis that in patients with spontaneous ICH, treatment with tranexamic acid within 2 hours of onset will reduce haematoma expansion compared to placebo.
Gastro intestinal (GI) bleeding is relatively frequent and may lead to intensive care unit admission. Although a restrictive strategy for red blood cell transfusion is supported by a large randomized controlled trial literature, less is known about the impact of transfusion strategy of other blood components and administration of anti fibrinolytic on clinical outcomes. This study aims to identify parameters that may be associated with the risk of further bleeding in patients admitted to ICU for GI bleeding.
Knee arthroplasty is performed with restriction of blood flow by use of the pressure tourniquet. Ischemia of skeletal musculature is accompanied by the formation of reactive oxygen species and release of vasoactive factors. Inhaled anesthetics were described as possible protective factors, termed "ischemic preconditioning". The objective of this investigation is to observe the effects of preconditioning with inhaled anesthetic on bleeding in the postoperative period of knee arthroplasty surgery. The study will be prospective and randomized. Patients will be allocated by means of a randomized table in two groups: Group Preconditioning (GP) - subarachnoid and general anesthesia with preconditioning with 1 minimal alveolar concentration (MAC) for 15 minutes before the installation of the ischemia by tourniquet; Group control (GC) - subarachnoid and general anesthesia with sevoflurane without preconditioning. Will be evaluated: hemoglobin and hematocrit, platelet count and coagulogram, electrolytes and creatinine, lactate and glycemia. Volume of drainage will be evaluated until drainage is withdrawn and need for transfusion measuring the number of bags of blood concentrate and volume transfused. Pain assessment will be done by means of visual analog scale. Morbidity will be recorded up to the 30th postoperative day by chart analysis. Patients will be allocated to the study groups by random number table. Data will be presented descriptively, frequently, mean and standard deviation, or medians and distribution in 25-75% percentiles. The comparison between continuous measurements will be made by means of repeated measures intra-group analysis of variance (ANOVA) and Student's t-test for evaluation between groups. The need for transfusion will be compared by Fisher's exact test. Pain intensity will be compared by Wilcoxon test for non-parametric data. A commercially available statistical package - SPSS version 15.0 (SPSS Inc.) will be used. A value of P <0.05 will be considered statistically significant.
The investigators propose a technique using cone beam CT perfusion (CBCTP) imaging with an acetazolamide challenge as a potential diagnostic tool to detect a defect in cerebral autoregulation at a time when it has not yet caused clinically apparent signs or symptoms. 30 participants will be enrolled at the University of Wisconsin - Madison and can expect to be on study for about 2 weeks.
The aim is to conduct a double-blinded single-centre randomized controlled clinical trial of application of topical dose of tranexamic acid (TA) versus the usual intravenous TA in patients undergoing cardiac surgery at the Hamilton General Hospital. This pilot study will assess the feasibility to perform a large randomized international trial exploring this objective.
Patients who are critically ill in the in the Intensive Care Unit (ICU), especially those who need a breathing machine, can develop ulcers in the stomach that bleed. To prevent bleeding, many such patients around the world receive a drug called pantoprazole that decreases acid production. However, today, compared to decades ago, critically ill patients rarely develop upper gastrointestinal bleeding. This decrease is likely due to modern medicine, better resuscitation and earlier feeding. There may also be harms associated with pantoprazole and other drugs that reduce acid levels in the stomach including lung infections (pneumonia) and bowel infections (Clostridioides difficile). Studies in this area are old and of modest quality. Therefore, it is difficult to know whether pantoprazole does decrease stomach bleeding these days, or whether the possible harms of lung and bowel infections are actually more common and more serious problems. The goal of this international study is to determine if, in critically ill patients using breathing machines, the use of pantoprazole is effective in preventing bleeding from stomach ulcers or whether it causes more problems such as lung infection (pneumonia) and bowel infection (Clostridioides difficile), or whether pantoprazole has no effect at all. Whether the harms are worth the benefits, and whether the benefits are worth the costs, will be determined by an economic analysis to inform patients, families, clinicians, and healthcare systems globally.
