Filter by:The purpose of this study is to determine that a new drug called "Rivaroxaban®" is effective in preventing patients from forming clots after their heart rhythm has been reset by the cardiologist with an electrical device.
Intrauterine devices (IUDs) are an effective form of contraception, but only about 3.4% of women in the US report using them. Women must often wait for their menses to start, or for results of screening for sexually transmitted infections (STIs), before their doctors will place IUDs for them. This is not the case with other birth control methods. Researchers know that it is safe to start oral contraceptive pills, transdermal patches or vaginal rings on the same day of a doctor's visit. In the investigators clinical practice, the investigators often place IUDs on the same day of a woman's visit, but outcomes have not been formally assessed. Currently, there are two kinds of IUDs available in the United States: the ParaGard T380A and the Mirena levonorgestrel intrauterine system (LNG-IUS). The investigators want to know if women who have IUDs placed at any time during their menstrual cycle have different experiences regarding the following, compared to those who have IUDS placed during the first 7 days of their cycle: bleeding or cramping patterns, active pelvic infections, becoming pregnant more often during that first cycle (window pregnancy). Women who come to their provider seeking an IUD for birth control will be asked to participate in this study. The investigators will ask them to keep track of their bleeding and cramping for three subsequent months to see if patterns differ according to the day in their menstrual cycle that the device was inserted. They will be randomly assigned either to record this information on paper, or to send in the information by responding to daily text messages. The investigators want to know if women who have an IUD placed at any time during the menstrual cycle have different outcomes compared to those who have IUDs placed during the first 7 days of their cycle. If the investigators have this information, the investigators can make recommendations to physicians, help counsel patients, and potentially expand access to IUDs.
Tranexamic acid has benn widely used to reduce perioperative bleeding in several operations such as cardiac surgery, liver transplant and joint arthroplasty with good results. Few studies in laminectomy had conflicting results and varying in doses. The objective is to compare perioperative bleeding in major laminectomy between patients receive doubles doses of tranexamic acids (15 mg/kg and 15 mg/kg) with who receive pacebo (0.9% NaCl).
The purpose of this study is to demonstrate that a BioFreedom™ Drug Coated Stent is non-inferior to a bare metal stent at one year as measured by the composite safety endpoint of cardiovascular death, myocardial infarction and definite/probable stent thrombosis, and that its efficacy is superior to a bare metal stent as measured by clinically driven TLR at one year.
Protamine is used after Cardiopulmonary Bypass (CPB) to reverse the anticoagulant effects of heparin and restore coagulation. Convincing evidence from in-vitro and in-vivo studies suggest that an overdose of protamine has anticoagulant effects which might lead to bleeding complications. Heparin levels usually decrease during cardiac surgery with CPB. Therefore, a protamine regimen based on the initial heparin dose before CPB might lead to overdose of protamine. In contrast, a protamine regimen based on the actual heparin concentration may avoid this condition. The investigators compare both regimens of protamine dosing in patients undergoing complex surgery with CPB and assess its effect on the amount of protamine given, markers of the coagulation system, utilization of blood products and perioperative blood loss.
The rFVIIa (Novoseven) has been tested in traumatic hemorrhage but its efficiency has not been proven yet in this context. A national register has been set up in France identifying the patients which received rFVIIa. Those patients had persistent and active bleeding after severe trauma despite surgery and/or interventional radiology embolization. The aim of this present study is to report the first clinical results in those situations of patients treated with rFVIIa.
The objective of this study is to determine the dose response relationship regarding blood loss, PK, PD and clinical outcomes of MDCO-2010 in comparison to placebo and tranexamic acid in patients undergoing primary cardiac surgery with cardiopulmonary bypass. The aim of the study is to define minimally effective dose of MDCO-2010.
The purpose of the study is to assess the coagulation changes that occur in laboring patients undergoing non-elective (intrapartum)Cesarean delivery using thromboelastography (TEG). We will compare coagulation data to assess potential coagulation changes associated with hemoglobin changes before and after surgery, and related to estimated blood loss.
Present trial is one of two trials (the other being a trial in hepatic resection surgery also comparing TachoSil® and Surgicel® Original) targeted toward providing clinical safety and efficacy data to support a general hemostasis indication across several surgical procedures and organ systems in the USA. The patient will come for a screening and baseline visit, the day of surgery and follow up visits after 1 months, 3 months and 6 months. The enrollment period is planned for 16 months and 6 months of follow up.
The aim of the study is to evaluate if there is an association between platelet inhibition and surgery-related bleeding in patients undergoing emergent cardiac surgery during dual antiplatelet therapy.
