The Efficacy of the Administration of Fibrinogen in Liver Transplantation
Intraoperative BleedingObjective: To evaluate the efficacy of preoperative administration of fibrinogen in liver transplantation by maintaining a preoperative plasma level equal to 2.9 g / L compared with placebo, reflecting a reduction in the number of RBC units transfused during the procedure. To determine the influence of fibrinogen administration on mortality and survival of liver graft evaluated one year after the procedure. To determine the safety of fibrinogen administration recording thrombotic complications evaluated during hospitalization or at least 30 days postoperatively.
Prospective Double-blind Study for the Use of Aspirin During Transurethral Surgery of the Bladder...
Blood LossSurgical2 moreAspirin is very common in older patients. Therefore many of the investigators patients have aspirin. The aim of the study is to proof that Transurethral Surgery of the bladder or the prostate can be performed with aspirin.
Mediastinal Temperature and Post-operative Bleeding
Blood LossSurgicalThis 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.
Pilot Study Differential Dissector™ for Blunt Dissection
Surgical AdhesionsBlood Loss1 moreThe primary purpose of this study is to evaluate the quality of blunt dissection during abdominal and pelvic surgery involving dissection of adhesions, separation of blood vessels and neurovascular structures while preserving the integrity of these structures.
Blood Loss Evaluation Using a Novel Device
Blood LossSurgical2 moreThe study´s aim is to evaluate the clinical applicability of the Feature Extraction Technology (FET) during a simulated blood loss scenario.
Association of Anemia With Hospital Costs in Elective Colorectal Surgery
SurgerySurgical Blood Loss3 moreThe objective is to measure the adjusted association between preoperative anemia and total hospital costs. We hypothesize that patients with anemia before surgery will have higher hospitalization costs than people without anemia.
Pre-surgical Evaluation for the Quantra System in Adult Patients Undergoing Cardiac Surgery
Blood LossSurgicalThis study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the QPlus Cartridge in patients taking anitplatelet medication that are scheduled to undergo cardiac surgery.
Estimated Blood Loss: Novel Model for Estimating Surgical Blood Loss.
Blood LossSurgical3 moreEstimated blood loss is an important parameter recognized as a standard practice in anesthesiology and others medical specialties, with relevant clinical and research applications. Currently is no model capable of accurately estimate blood loss. The purpose of this study is to evaluate the accuracy of a novel model.
Evaluation of the Quantra System in a Surgical Oncological Population
Blood LossSurgicalThis study will monitor coagulation parameters during the perioperative course of cancer surgical procedures using the Quantra System with the QPlus Cartridge.
Non-inferiority Trial of Oral Tranexamic Acid vs. Intravenous Tranexamic Acid in Joint Replacement...
OsteoarthritisBlood Loss3 moreThe purpose of this research is to determine if the oral form of a medication (tranexamic acid) to reduce bleeding can be used in place of an intravenous (IV) form, to learn the best way to give tranexamic acid: either a pill by mouth, or a solution by vein.
