Filter by:Post-operative, throat pain, nausea and vomiting is a common occurrence in rhinology surgeries due to the use of throat packs during the procedure. In order to optimize quality of care and patient satisfaction, the aim of this study to evaluate the incidence of post-operative, throat pain, nausea and vomiting in patients that have been packed with either conventional gauze throat packs or pharyngeal tampons.
The purpose of the study is to assess efficacy and safety of HemoStyp as an adjunct for management of secondary hemostasis in the operative setting.
Disorders of platelet function are characterized by variable mucocutaneous bleeding manifestations and excessive hemorrhage following surgical procedures or trauma. Generally, most patients have mild to moderate bleeding manifestations with a prolonged bleeding time. Platelet aggregation and secretion studies using platelet-rich plasma (PRP) provide evidence for platelet dysfunction but are neither predictive of severity of clinical manifestations nor the molecular mechanisms. Glanzmann's thrombasthenia (GT) is a rare autosomal recessive genetic bleeding syndrome characterized by defects in platelet aggregometry. The clinical phenotype of patients with GT is variable. Some suffer from severe bleeding, while others have only mild bleeding. Some studies found bleeding severity in GT was influenced by the abundance and functioning of platelet receptors involved in aggregation and adhesion. In addition to a complete medical history, a GT diagnosis requires a comprehensive laboratory workup, including platelet aggregation analysis, and a confirmation by flowcytometry or western blotting with monoclonal antibodies that recognize the GPIIb/IIIa complex. Platelet flow cytometry is an emerging tool in diagnostic and therapeutic hematology. It is eminently suited to study the expression of platelet surface receptors both qualitatively as well as quantitatively. Aim of the study:- - Determine the role of flowcytometry as a quantitative measurement tool of platelets surface glycoproteins in patients with inherited thrombocytopathies and its correlation with bleeding severity of these patients. - To compare the efficacy, advantages and disadvantages between platelets flowcytometry and aggregometer in diagnosing various inherited thrombocytopathies.
The researchers are trying to reduce the need for blood transfusions in subjects having surgery that will involve the use of cardiopulmonary bypass. A unit of whole blood will be removed as part of their standard of care prior to going on cardiopulmonary bypass (CPB). This unit is given back to the subject post CPB. This has been shown to reduce the need for blood transfusion in patients.
This study aims to assess the 6- and 12-month venous thromboembolism (VTE) and bleeding incidence from the start of cancer diagnosis in a retrospective cohort of patients with esophageal cancer. Additionally, the predictive value of the Khorana score and several other VTE and bleeding prediction scores and risk factors will be evaluated.
A prospective open-label case-control study will be performed aiming to assess the utility of thromboelastometry (ROTEM) for identification of hemostatic changes, goal-directed coagulation management, and prognosis of intracranial hemorrhagic injury progression as well as clinical outcome in patients with isolated traumatic brain injury. Patients undergoing craniotomy to treat traumatic brain injury will be enrolled. All patients will undergo standard perioperative coagulation analysis (APTT, PT, INR, fibrinogen levels, platelet count), whereas ROTEM-guided group will additionally be tested with ROTEM. "Cases" will be managed according to a ROTEM-based algorithm, and "Controls" will be treated as usual (based on clinical judging). Comparative analysis of acquired demographic, clinical and laboratory data will be performed. The investigators believe that ROTEM results could provide better insight into perioperative coagulation changes, be beneficial to patient blood management, and result in better outcome.
Tranexamic acid has been shown to be effective in reducing blood loss and transfusion in orthopedic surgery. It remains unknown the ideal therapeutic regimen. The goal of this study is to compare 3 dosage regimen of tranexamic acid in patients submitted to major orthopedic surgery.
The objective of the study is to compare short-term (8 weeks) anticoagulation therapy (DOAC) vs. antiplatelet therapy for the prevention of device thrombosis following transcatheter LAAC.
As bleeding is a major risk in bariatric surgeries, we aimed our study to find any predictors to such bleeding within the surgery or 30 days after surgery. The study is a retrospective study collecting patients data, surgeons data, and hospitals data in order to find if any of the factors influencing patients, surgeons or hospitals, has to do with bleeding in these surgeries and if it does impact bleeding in what way. The goal is finding a predictor that it's neutralizing may prevent bleeding in bariatric surgeries.
Multicenter case cohort study investigating clinical risk factors for clinically relevant bleeding in hemato-oncology patients, as well as bleeding related biomarkers during intensive treatment.
