Filter by:In endoscopic sinus surgery a clear surgical field of view is a very important aspect for good surgical outcome. This study is to evaluate the preoperative preparation to acquire best surgical field of view by comparing between the use of topical adrenaline and the use of combination of topical adrenaline with infiltration of 1% lidocaine with adrenaline in patients scheduled for endoscopic sinus surgery for rhinosinusitis.
This is a pre-market, prospective, randomized (2:1), multicenter, multi-national pivotal clinical investigation. The purpose of this investigation is to determine the clinical safety and performance of GATT-Patch as compared with TachoSil for the management of minimal, mild, or moderate bleeding during elective open liver surgery.
Exploratory tympanotomy is surgical access to the middle ear, made for diagnosis and management of unexplained conductive hearing loss, performed under an oto-microscope across the external auditory canal after tympanic membrane elevation to explore the middle ear structures
A full medical history will be obtained from all participants. Obstetric ultrasonography and laboratory tests will be performed.According to group assignment, either 1 g(10 mL) tranexamic acid stored in a dry container at 15 °C-30 °C) diluted in 20 mL of 5% glucose or 30 mL of 5% glucose will be slowly administered intravenously 15 minutes before skin incision over a 5-minute period. Following delivery, patients in both groups will receive an intravenous bolus of 5 IU oxytocin , 1 mL(0.2 mg) intramuscular ergometrine , and 20 IU oxytocin in 500 mL lactated Ringer's solution(infused at a rate of 125 mL/h)
Functional endoscopic sinus surgery (FESS) is a commonly performed procedure. It is known that bleeding during FESS can affect directly to the visibility of safe landmarks and surgical outcomes.
Purpose of the study: - To evaluate the effect of tranexamic acid (TXA) of intraoperative blood loss in patients subjected to bi-maxillary orthognathic surgery - To evaluate the potential effect of TXA on fibrin structure - To evaluate the potential effect of TXA of binding of plasminogen to fibrin - To evaluate the potential effect of TXA on postoperative edema formation. Hypothesis: H0: Intraoperative bleeding cannot be significantly reduced by preoperative administration of tranexamic acid H0,1: Postoperative edema cannot be significantly reduced by preoperative administration of tranexamic acid
The purpose of this study is to compare Floseal to our standard of care (SOC) to decrease intraoperative and immediate post-operative bleeding.
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.
