177 Clinical Trials for Various Conditions
The objective of this study is to determine if tAN therapy can reduce the volume of blood lost during dialysis AV graft placement procedures.
Although serious complications from second trimester abortion are rare hemorrhage is the most common cause of procedural abortion related morbidity and mortality. Misoprostol is a prostaglandin E1 analogue that is used by 75% of clinicians prior to procedural abortion for the purpose of cervical preparation. Misoprostol is also known to decrease blood loss in first trimester abortion and is used to treat postpartum hemorrhage, however the effect of preprocedural misoprostol on procedural blood loss is not well described. We will conduct a double blinded placebo-controlled gestational age stratified superiority trial of those undergoing procedural abortion between 18 and 23 weeks gestation at Stanford Health care. Participants will be randomized to either 400mcg buccal misoprostol or placebo on the day of the procedure. A quantified blood loss (QBL) will be measured during the procedure and participants will complete a survey to assess symptoms. Our primary outcome is quantified blood loss. Secondary outcomes include clinical interventions to manage excess bleeding, total procedure time, provider reported experience, patient reported experience.
To examine in Arista hemostatic powder results in less post-total knee arthroplasty blood loss, hematoma formation, and improved range of motion when compared to patients who did not receive the product.
Prospective, Multicenter, Double-blind, Randomized, Study to Evaluate DrugSorb-ATR Removal of Apixaban and Rivaroxaban to Reduce Likelihood of Serious Bleeding in Patients Undergoing Urgent Cardiothoracic Surgery
Prospective, multi-center, double-blind, randomized pivotal trial to evaluate the safety and effectiveness of the DrugSorb-Antithrombotic Removal (ATR) system for intraoperative removal of ticagrelor in patients undergoing urgent cardiothoracic (CT) surgery with cardiopulmonary bypass (CPB).
This study will investigate how chest temperature relates to blood loss and blood clotting. Researchers will use infra-red thermometers to measure the temperature of the chest at the end of surgery see if this relates to the amount of blood collected from the surgical drains. In addition, researchers will test if warm irrigation of the chest increases the temperature of the chest and if this impacts blood loss.
The purpose of this investigation is to determine the most effective regimen of administration of tranexamic acid to improve clinical outcome among patients undergoing total knee arthroplasty.

This study will evaluate if the timing of oxytocin administration in cesarean deliveries will affect the amount of maternal blood loss. Half of participants will receive oxytocin after delivery of the fetal anterior shoulder and the other half will receive oxytocin after delivery of the placenta. We hypothesize that administering oxytocin after delivery of the shoulder, will result in less overall maternal blood loss.
This study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the Quantra Surgical Cartridge in patients undergoing major surgical procedures specifically, major cardiac and vascular procedures and major orthopedic surgery (primarily complex spine surgeries).
The purpose of this project is to compare the effectiveness of two different but well accepted routes of administration of tranexamic acid in order to reduce blood loss and need for transfusion in patients undergoing lumbar spine surgery. Specifically, this study seeks to identify if intravenous tranexamic acid is superior to oral tranexamic acid in reducing blood loss and need for transfusion.
This is a prospective, multicenter, multidisciplinary, controlled clinical investigation evaluating the safety and efficacy of PerClot in achieving intraoperative hemostasis compared to a similar marketed hemostatic device. Three hundred and twenty four subjects across a maximum of 25 investigational sites undergoing open elective cardiac, general, or urological surgical procedures who meet the eligibility criteria will be intraoperatively randomized to receive no more than the entire contents of up to two 5 gram bellows of either the investigational device or a control hemostatic agent on a bleeding site, whose anatomic site is smaller than or equal to 25cm² and whose anatomic application site is smaller than or equal to 47cm², when bleeding is within the pre-defined bleeding severity range after any applicable conventional means for hemostasis are attempted as specified in the intraoperative procedures. Each investigational site is expected to enroll approximately 13-40 subjects. All investigational sites will be located in the U.S. Follow-up will occur at hospital discharge and 6 weeks post-device application. For oncologic subjects, an additional follow up will occur at 24 months post device application.
The main purpose of this study is to compare blood loss at the time of laparoscopic or robotically-assisted laparoscopic myomectomy when using different amounts of dilute vasopressin solution. Myomectomy is a surgical procedure to remove fibroids from the uterus. Vasopressin is a synthetic drug used to help decrease blood loss at the time of gynecologic surgery; although very little is know about the optimal dosage and administration. The investigators plan to perform a randomized clinical trial on patients scheduled for minimally invasive myomectomy. All patients will get the same overall amount of vasopressin. Patients will be assigned by chance to one of two groups: one group will receive higher volume of a more dilute vasopressin solution. The other group will receive a lower volume of a more concentrated solution. The investigators will collect information on operative blood loss and complications related to surgery.
The objective of this study is to assess the safety and immunogenicity of recombinant thrombin (rThrombin) administered as an aid to hemostasis during burn wound excision and skin grafting in pediatric patients, newborn through 17 years of age.
The objective of this study is to assess the immunogenicity and safety of recombinant Thrombin (rThrombin) in patients with prior rThrombin exposure.
The purpose of this study is to assess if aprotinin (BAY A0128), given intravenously during surgery, is safe and can help reduce the amount of bleeding and the need for a blood transfusion during hip replacement surgery. Patients undergoing major surgery are at risk for significant blood loss. Because of this, there is a need for drugs that will help slow the amount of bleeding during surgery.
The primary objective of this study was to assess the efficacy and safety of 2 dose levels of ecallantide versus placebo in reducing blood loss following cardiopulmonary bypass (CPB), as measured by chest tube drainage during the first 12 hours postoperatively or until the chest tube was removed, whichever came first, in patients undergoing primary coronary artery bypass grafting (CABG), single valve repair, or single valve replacement. The secondary objective was to compare the efficacy of all ecallantide-treated participants (pooled high and low-doses) to placebo and to compare the high-dose to the low-dose ecallantide group. Other secondary objectives were to evaluate pharmacokinetics and antibody formation.
This is a progressive dose escalation study designed to evaluate the safety of Hemospan compared to a standard crystalloid solution (Ringer's lactate) in elective surgery patients undergoing total prostatectomy procedures with anticipated blood loss of more than 500 mL. Secondary objectives of this study are to observe possible activity of Hemospan for tissue oxygenation, perfusion and cardiovascular support.
A comparison of fibrin sealant 2 versus Surgicel® as an addition to standard surgical practice in stopping mild to moderate soft tissue bleeding during retroperitoneal or intra-abdominal surgery.
The purpose of this study is to assess if aprotinin (BAYA0128), given intravenously during your surgery, is safe and can help reduce the need for a blood transfusion during bladder surgery.
Study to Investigate the Effect of Aprotinin of Transfusion Requirements in Patients Undergoing Surgical Procedures for Lung or Esophageal Cancer.
After a child has their tonsils removed, sometimes they might bleed which can be a problem. There is a special mist medicine called nebulized tranexamic acid (TXA) that might help stop the bleeding without having to touch the sore spot. If this mist works well, it could help kids get better by making sure they don't have to go back for more surgery or need blood from someone else. Not having another surgery is good because it means kids won't have to sleep under medicine again, which can sometimes be risky for their brains and breathing, and they won't feel as scared or hurt.
Tranexamic acid (TXA) is a synthetic anti-fibrinolytic agent that has been well studied and routinely used for hip and knee arthroplasty. In hip and knee arthroplasty, the use of tranexamic acid decreases blood loss and the need for transfusion without increasing the risk of thromboembolic events. Due to the increased use of reverse total shoulder arthroplasty in the treatment of shoulder pathology, there has been interest in making the procedure safer for patients. TXA is a promising drug which could be useful to surgeons as they seek to achieve this goal, however, it has not been extensively studied in this setting. The purpose of this prospective randomized, controlled study is to determine the effectiveness and safety of using tranexamic acid to decrease blood loss in reverse total shoulder arthroplasty.
Tranexamic acid (TXA) is a synthetic, competitive lysine receptor inhibitor on plasminogen. It ultimately stabilizes the fibrin matrix, therefore used as a hemostatic agent for various indications. While there has been indications for orthopedic and trauma surgery, there is no clear data for its role in patients who are undergoing free tissue transfer. Studies have shown that patients undergoing free tissue transfer can have transfusion rates ranging from 7.2% to 34.9%, which data also showing association between transfusion requirement and higher free flap failure rate. There has been a few retrospective studies that evaluated the effect of TXA in free tissue transfer and the results showed no increased risk of microanastomosis failure but some showing decreased blood loss. This study aims to further analyze the role of TXA in patients undergoing breast free flap reconstruction with randomized, prospective trial. Control group will not receive TXA while experimental group will receive TXA. Both groups will receive standard of care breast free flap surgery as well as post-op care, which is streamlined with Early Recovery After Surgery (ERAS) protocol. Their pre and post-op hemoglobin will be compared, as well as rates of transfusion, surgical outcome and surgical complications including hematoma, flap failure, and any other medical complications such as Deep Vein Thrombosis (DVT)/ Pulmonary Embolism (PE).
This prospective study will analyze the need for deliberate hypotensive anesthesia (DHA) during orthognathic surgery when tranexamic acid (TXA) is administered. DHA has been proven to be effective although it comes with multiple risks related to organ hypoperfusion including kidney injury, stroke, and cardiac ischemia. Therefore, it may be potentially safer for patients to avoid deliberate hypotensive anesthesia if TXA alone adequately controls blood loss and provides adequate surgical site visualization.
Posterior spinal surgery for adult deformity is associated with high incidence of blood loss and need for blood transfusion and intraoperative blood salvage, with associated increased cost and risk for perioperative complications. Tranexamic acid (TXA) is relatively inexpensive anti-fibrinolytic agent that has been proven effective for decreasing intraoperative blood loss in various surgical specialties. Intravenous TXA (ivTXA) is routinely used at our institution for adult spinal deformity cases. Meanwhile, topical TXA (tTXA) is an attractive alternative/adjunct to ivTXA used with good results in orthopedic arthroplasty and cardiac surgery. To the investigators' knowledge, no data exists in the literature on the use of tTXA in either adult or pediatric spinal deformity surgery. The goal of this study is to determine the role tTXA has an adjunct to ivTXA in decreasing perioperative blood loss, drainage, transfusion requirements and length of stay following adult deformity spine surgery.
The objective of this study is to determine the effect of 1g of IV tranexamic acid given within 1 hour pre-operatively on intraoperative blood loss at time of hysterectomy.
