Active clinical trials for "Hemorrhage"

Clinician counseling for implant users should involve an explanation of the likelihood of irregular bleeding and the possibility of continued or frequent bleeding throughout three years of use. If that counseling does not provide specifics of the actual distribution of bleeding patterns described in published literature, there remains the real possibility of biased or directed counseling, leading to an inaccurate and exaggerated expectation of potential bleeding changes. This study aims to evaluate if a standardized script accompanied by a visual aid regarding expected bleeding profiles, with intention to remove any possibility of negative or positive framing, could change users' expectations and satisfaction with their method, leading to lower discontinuation rates.

After surgical procedures, interventions to reduce postoperative bleeding are of great importance. In this study, the effect will be investigated of administering tranexamic acid, which is designed for injection, directly onto the raw wound surface (topical application) created during surgery. In this way only a small amount of drug is to reach a large wound area. There will be a higher drug concentration of it in the exposed wound surface than after injection, but only a very low concentration in the body, and no risk of injury from needles. The researchers have recently shown that topically applicated tranexamic acid reduces bleeding in women who had two-sided breast reduction surgery. Now it will be studied whether topically applicated tranexamic acid reduces bleeding from superficial wounds, using as a study model the homogenous wounds created by tangential skin excision when harvesting split skin grafts for skin transplants. Two identical wound surfaces in the same patient will serve as case and control.

The purpose of this study is to determine whether inhaled nitric oxide improves the neurological outcome for premature infants.

Postmenopausal bleeding (PMB) is a common gynaecological complaint, accounting for up to 5 to 10 % of postmenopausal women being referred to gynaecological outpatient clinic. It also comprised of up to 10% of our outpatient gynaecological referral. In general, 60 % of women with postmenopausal bleeding have no organic causes identified, whilst benign causes of PMB includes atrophic vaginitis, endometrial polyp, submucosal fibroid and functional endometrium. However, between 5.7 to 11.5% of women with postmenopausal bleeding have endometrial carcinoma, which is the fourth most common cancer among women, therefore, it is important to investigate carefully to exclude genital tract cancer. A One-stop postmenopausal bleeding clinic has been established since February, 2002 by the Department of Obstetrics and Gynaecology, New Territories East cluster (NTEC) aiming at providing immediate assessment of women with postmenopausal bleeding in one single outpatient clinic assessment. During the visit, a detailed history was taken in regarding the PMB and usage of hormonal replacement therapy or herbal medicine. A physical examination was performed and a cervical smear was taken if not been taken within a year. Transvaginal ultrasound (TVS) was then performed to measure the endometrial thickness (ET), examining ovaries then followed by an endometrial sampling. An outpatient hysteroscopy was performed only if TVS showed an ET >= 5mm, or an abnormal endometrial appearance or unsatisfactory ET. Benign looking endometrial polyp would be removed during the outpatient hysteroscopy if possible. At the moment, there was very limited local data and lack of the long term result. Investigators aim to retrospectively evaluate the clinical outcome of postmenopausal bleeding patients who has attended One Stop Postmenopausal Clinic in order to formulate better care and counseling in future. Objectives: To analyze histopathology in relative to history and ultrasound findings in PMB women presented to One Stop Postmenopausal Bleeding Clinic at NTEC To correlate the clinical findings of transvaginal ultrasonography (TVS) with outpatient hysteroscopy and endometrial assessment in The One Stop Postmenopausal Bleeding Clinic To identify predictive and prognostic factors in women with PMB for possible use in triaging high risk patients

Severe and un-stopped blood loss can occur for a number of different reasons including after a serious injury, delivery of a baby and following other medical and surgical emergencies. The investigators understanding of how to best treat people with serious bleeding is still incomplete, with many questions remaining. These include questions regarding how many people have serious bleeding events, what happens to them and the best way to treat them. The Massive Transfusion Registry (MTR) is a register of patients who have experienced major blood loss that required a massive transfusion in any clinical setting. The MTR uses electronic data extraction and data linkage methodologies. Pre-existing clinical data from hospital data sources, including Laboratory Information Systems (for transfusion history and laboratory results) and Health Information Services databases (for Patient demographics and admission data), are electronically extracted by staff employed at the participating hospitals. The data is then sent to the MTR Research Team, located at Monash University, where it is then linked, analysed and stored. The establishment of a Massive Transfusion Registry will be a unique and important resource for clinicians in Australia, New Zealand and internationally, for Blood Services and for the broader community. It will provide valuable observational data regarding the types and frequency of conditions associated with critical bleeding requiring massive transfusion, the use of blood component therapy (i.e. ratios and quantities of different types of red cell to non- red cell components) and patient outcomes.

The registry is the main objective exhaustive list of cases validated stroke brain on a geographical area defined to calculate an incidence.

In this study, the investigators will compare the frequency and amount of bleeding after tubal sterilization and salpingectomy

The research study is to explore novel early predictors and validation of laboratory parameters in the management of sepsis in critically ill patients especially with brain injuries and systemic inflammatory response syndrome (SIRS).

Nearly half of the survivors of subarachnoid haemorrhage (SAH) retain irreversible neurological damage resulting from the early lesions associated with the initial bleeding, and the occurrence of possible delayed cerebral ischaemia (DCI). The early diagnosis of the occurrence of an DCI is therefore a major challenge in order to optimise management before irreversible lesions are formed. However, the means of diagnosis are often not available, and up to a third of DCI are discovered on follow-up images when the lesions are already present. Among the markers of brain injury, S100 calcium-binding protein B (S100B) is an astrocyte protein released into the bloodstream at the time of the appearance of a brain lesion. Its short half-life makes it a prime candidate for patient follow-up to diagnose a new ischemic lesion and assess the effectiveness of its management. Among the elements at the origin of DCI, the occurrence of proximal vasospasm is the main element on which we can have a therapeutic action. The strategy implemented in the department consists of performing a mechanical angioplasty when proximal vasospasm is detected with a decrease in downstream cerebral perfusion. Nevertheless the benefit of this therapeutic action is discussed and there is currently no early marker of the effectiveness of this procedure.

The investigators design a retrospective, observational cohort study to provide contemporary information on the prevalence, characteristics, risk stratification，cost-effective, treatments and prognosis of Chinese hospitalized adult patients with intracerebral hemorrhage.
