When having certain types of outpatient surgery inside the uterine cavity some women experience heavy bleeding. The only method presently available for controlling such bleeding, short of removing the uterus, involves the placement of a balloon pressure device inside the uterine cavity. The pressure along with the patient's own natural clotting ability will generally stop the bleeding. However, this treatment usually requires at least a 24 hour stay in the hospital. The investigators are researching the use of a compound (FloSeal) already approved for use in other areas of the human body, as a method of controlling bleeding. The use of FloSeal in the uterine cavity has not yet been tested and therefore is not yet an FDA approved indication for its safe use to control bleeding from the uterine cavity. In this study, The investigators want to find out what effect(s) FloSeal has on the uterine cavity. Twenty individuals will be included in this study at Northwest Hospital Center. All twenty individuals will be treated in the same fashion except ten of the participants will randomly be assigned to receive FloSeal and ten will not. Study participants are individuals currently scheduled to have a hysterectomy procedure, which involves surgically removing the uterus from the body for a previously determined standard of care treatment for a non- cancerous medical problem. Before performing the hysterectomy and evaluating the effects of FloSeal upon the tissues within the uterine cavity the following will be done. Once under anesthesia the uterine cavity will be subjected to a curettage (sharp scrapping) to produce a minor amount of bleeding from the lining of the uterus. Ten of the 20 study participants, randomly chosen, will then have FloSeal placed into their uterine cavity. The study participants will not know whether they received FloSeal or not. A balloon pressure device will then be placed into the uterine cavity of all 20 individuals and left in place for 5 minutes. After the allotted time, the balloon device will be removed. The hysterectomy will then be completed appropriately using standard methods and techniques. The uterus, once removed will be evaluated pathologically to determine the effects of the FloSeal upon the tissues of the cavity in those so treated and compared to the same analysis in those individuals who did not receive FloSeal. The pathologist will not know which patients received or did not receive FloSeal. This use of FloSeal is not currently an FDA approved use of the compound. The goal of this study is to obtain FDA approval for use in this situation.
The standard of care for treatment of burn injury is to inject a solution of epinephrine under the skin of the injured site in order to reduce blood loss during skin grafting. This solution of epinephrine has been shown to have effects on the body outside the donor site. Some people have increases in heart rate and blood pressure. We will study the effect of a phenylephrine solution in place of an epinephrine solution to control blood loss. We think that phenylephrine will help decrease blood loss and not change blood pressure or heart rate. The injured area will be injected under the skin and a skin graft will be taken in the same way as we usually do. The only change will be the use of phenylephrine in the solution instead of epinephrine. Our goal is to find whether or not phenylephrine or epinephrine solution results in a reduction of blood loss without affecting the rest of the body.
Applying a fibrin spray, after knee device implantation, will help in reducing patient blood loss and decrease the drop in both hemoglobin and hematocrit levels. Also, with decreased blood loss there should be a reduced need for blood transfusions.
Hypotheses: Primary - A weighted dose of 20 mg/kg of tranexamic acid will be more efficacious than a single uniform dose of 1 gram in primary total knee arthroplasty (TKA) cases. This includes having a greater impact on decreasing blood loss without increasing the occurrence of adverse thromboembolic events in patients undergoing primary, elective total knee arthroplasty. Secondary - TA will decrease blood loss more effectively in women than in men undergoing this procedure.
The purpose of this study is to evaluate the safety and effectiveness of Traumastem to help stop bleeding in participants undergoing open cardiac, intra-abdominal (including retroperitoneal) and pelvic surgery as compared to Surgicel® Original (Surgicel; in some countries marketed as Tabotamp®)
Objective: - 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.
The purpose of this study is to demonstrate that Fibrinogen Concentrate (Human)(FCH) can reduce the amount of donor blood products needed during complex cardiovascular surgery, and that it is safe and well tolerated. Subjects in this study will get either a FCH or placebo infusion during surgery. This will be in addition to the standard treatment, which is donor blood or blood products. Placebo does not contain any effective medicine. The study is randomised. This means that the likelihood that subjects will get FCH or placebo is 50%. To make the comparison between FCH and placebo as fair as possible, the study is "double blind". This means that neither the subjects nor the study doctor will know if FCH or placebo is administered. If necessary, the study doctor can find out which treatment the subjects are receiving.
This is a prospective, multicenter, randomized, controlled investigation. Subjects in which bleeding from the exposed parenchymal surface is observed intraoperatively following the ligature of vessels visible with the unaided eye will be randomized to an adjunctive application of BioFoam or a standard topical hemostatic agent (Gelfoam with thrombin, in the form of Gelfoam Plus) to the entire exposed parenchymal surface. Following primary treatment of the exposed parenchymal surface as prescribed by the randomization scheme, treatment sites will be visually evaluated for the continued presence of bleeding. The overall objective of this investigation is to collect clinical data concerning the safety and effectiveness of BioFoam used as an adjunct to conservative measures of achieving hemostasis, such as manual pressure, cautery, and ligation, for intraoperative capillary, arteriolar, and venular bleeding (5 second stack of 5 gauze surface "Bleeding Score" = 1b or 2, score to be validated) on newly resected liver parenchyma in hemodynamically stable (American College of Surgeons' Advanced Trauma Life Support Class I Hemorrhage) and non-coagulopathic patients in the open treatment of exposed liver parenchyma versus a standard topical hemostatic agent, Gelfoam Plus. It is not intended for traumatic liver injury. The investigation will be conducted at a maximum of three investigational sites.
Tonsillectomy (removal of the tonsils) is a very common surgery in children. Bleeding after tonsillectomy is one of the risks of this surgery and can be more dangerous in children since they have less blood volume than adults. In order to improve recovery after tonsillectomy, steroids (medication that is a strong anti-inflammatory) are often given during the surgery. Recently, a study showed steroids given at the time of tonsillectomy increase the risk of bleeding significantly over children who did not receive steroids. This finding has raised concerns in the Ear, Nose, and Throat (ENT) community since most ENT's use steroids during tonsillectomy in children. The investigators look to explore this question further. To answer the question of whether perioperative steroid administration significantly affects the rate of post-tonsillectomy bleeding, the investigators propose to test the following hypotheses in a prospective, randomized, blinded placebo-controlled trial: dexamethasone does not cause an increase in post-operative bleeding rate in tonsillectomy.
