Filter by:After surgical procedures, interventions to reduce postoperative pain and bleeding are of great importance. In this study, the effect will be investigated of smearing common drugs, which are designed for injection, directly onto the raw wound surface (topical application) created during surgery. Topical application allows a small amount of drug to reach a large wound area, higher drug concentration in the exposed wound surface but very low concentration in the body, and no risk of injury from needles. Although beneficial effects of such an easy and low-cost intervention would be expected, the investigators have found no previous reports on blinded and controlled studies.
This double-blinded, placebo-controlled, randomized trial will compare the effects of the use of a combined oral contraceptive pill to a placebo pill for women who are experiencing irregular and/or heavy bleeding associated with the use of an etonogestrel (ETG) implant. The hypothesis of the study is: - Use of combined oral contraceptive will significantly improve bleeding patterns for users of ETG implant - Continuation rate of ETG implant users will be increased by use of combined oral contraceptive in women desiring ETG implant removal because of the undesirable bleeding - Adverse events will be uncommon and acceptable to women who use a combined oral contraceptive with the ETG implant
The occurence of a minor craniocerebral trauma in patients receiving vitamine K antagonist treatment leads to a high risk of bleeding. Current guidelines recommend to perform a CT scan, and, in case of intracranial bleeding, to reverse anticoagulation with concomitant administration of prothrombin complex concentrates (PCCs) and vitamin K. However, even if a reversion is performed, the prognostic of post-traumatic intracranial bleeding remain bad. The investigators hypothesize that, for patients admitted in an emergency department after a minor head trauma and receiving anticoagulant treatment, a systematic preventive reversion with PCCs can lead to a significant reduction of intracranial haemorrhage and can also improve the neurological prognostic of patients versus the current strategy. PREVACT will test this hypothesis, in an open label, randomized, multicentre, clinical trial involving 400 patients.
It is very important to decrease the bleeding during functional endoscopic sinus surgery (FESS) in order to increase the visibility of the surgical site. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on visibility of surgical site.
Evaluation of blood pressure variability in the acute phase of intraparenchimal cerebral haemorrhage and its consequences to clinical outcome
To investigate safety, tolerability, PK and PD of BI 655075 and to establish the BI 655075 dose(s) effective to reverse prolongation of blood coagulation time by dabigatran
Study of heterogeneity in associations between heart rate and the initial presentation of 12 cardiovascular diseases.
Visual impairment in high myopic eyes is mainly due to the different types of myopic maculopathies, such as diffuse or patchy atrophy, lacquer cracks and choroidal neovascularization. Macular hemorrhage was one of those complications. Despite choroidal neovascularization, simple hemorrhage from rupture of Bruch's membrane and choroidal microcirculation is also the cause of hemorrhage. The prognosis of those eyes with simple hemorrhage is generally good. However, some patients had persistently poor vision after the absorption of the hemorrhage. In the literature, the visual prognosis in those patients was reported to be associated with the microstructure change under the optical coherent tomography (OCT) or the presentation of the autofluorescence. The investigators will collect the patients with high myopia and presenting with macular hemorrhage. High resolution OCT and autofluorescence imaging will be used to analyze the change of the microstructure of retina and its correlation with the visual prognosis.
The goal of this study is to determine if the use of tranexamic acid, a safe and effective antifibrinolytic, in patients with intertrochanteric hip fractures will result in a reduction in blood transfusion rates. Treatment will be administered pre-operatively as well as at the time of surgical incision. The primary outcome will be need for blood transfusion. Secondary outcomes will include calculated perioperative blood loss, length of stay, cost of inpatient care, and rate of adverse events, including DVT, PE, infection, MI, cerebrovascular event, need for re-hospitalization or re-operation and 30 day mortality.
