Filter by:The purpose of this study is to determine the feasibility, safety and effectiveness of an endotracheal tube embedded with a mini video-camera as a guiding tool for percutaneous tracheostomy.
The purpose of this study is to compare the feasibility, safety, efficacy and ease of performance of a video-assisted PCT (via an endotracheal tube embedded with a mini video-camera) with the standard ("blind") PCT technique.
Warfarin is highly effective for the prevention of both first and recurrent thrombotic events, however even minor excursions outside the reference INR range of 2.0 to 3.0 are associated with bleeding or thrombotic complications. The importance of maintaining the INR within the desired interval has led to the concept of "time in therapeutic range (TTR)" - the total proportion of time that the INR is between 2.0 and 3.0. The investigators propose a multicentre, double blind, randomized trial which will determine if 0.150 mg of oral vitamin K increases time in the therapeutic range for patients receiving warfarin.
The study hypothesis is that prophylactic fibrinogen infusion reduces postoperative bleeding and transfusion requirements after coronary artery bypass surgery (CABG) in patients with endogenous fibrinogen levels in the lower normal range. 60 patients will be included in a prospective, randomized double-blind placebo-controlled single center study.
The purpose of this project is to describe the pathophysiology of thrombocytopenia and bleeding in patients with Wiskott-Aldrich Syndrome (WAS) and determine the response to thrombopoietic agents in vitro and in vivo.
It is well known that femoral neck fractures carry a significant increase in patients' mortality and that surgical intervention is the preferred treatment. Any delay in operating on such patients would inevitably increase their risk of developing complications. One of the reasons for such unintentional delay would be the hypercoagulative status of patients taking warfarin. The CHEST 2008 guidelines suggest reversing warfarin with Vitamin K for patients who need urgent operation. The aim of this study is to compare different roots and doses of Vitamin K.
the purpose of this study is to show that the vacuum control surgical bleeding helps stop bleeding extraMD (MD: Medical Device) at the orifice of the retrograde cannulation during a heart with Extra-corporeal circulation (ECC),
The purpose of this study was to evaluate the effect of guided imagery on the third stage of labor. Blood loss from hemorrhage during childbirth, most commonly due to uterine atony, is one of the leading causes of maternal mortality in the United States and the leading cause of maternal death worldwide. The hypothesis was that the use of physiologic guided imagery would reduce the amount of bleeding during the third stage of labor.
Patients with severe aortic stenosis often suffer from an acquired Von Willebrand syndrome by degeneration of the polymers during passage through the narrow valve leading to turbulences. We hypothesized that the diagnosis of acquired von Willebrand syndrome influence perioperative blood loss in patients undergoing open cardiac valve replacement.
We hypothesize that the addition of oral naproxen or transdermal estradiol will decrease the number of days of unscheduled bleeding experienced by first-time users of the levonorgestrel intrauterine system (LNG-IUC) during the first 12 weeks of use compared to an oral placebo. The objective of this study is to compare the total number of days of bleeding experienced by first time users of the LNG-IUC randomized to oral naproxen or estradiol patch compared to those randomized to placebo for the first 12 weeks of use. We will enroll women initiating LNG-IUC to one of 3 groups, transdermal estrogen, oral naproxen or oral placebo. We will enroll a total of 114 women, 38 in each group. Women will keep bleeding diaries for 16 weeks which will be used to calculate the total number of bleeding or spotting days. Statistical analysis will be performed to evaluate if there is less bleeding among the treatment arms then the placebo arm.
