Filter by:In spine surgery, it is important to try to minimize bleeding. In particular, spine surgery often involves inserting hardware into bone, and/or removing bone in the spine. Because the bone in the spine contains blood vessels, there can often be bleeding from the bone itself that is difficult to stop completely. One way to stop bone bleeding is through the use of wax-like materials, which plug the bleeding bone and act as a physical barrier to stop bleeding. One example is Ostene bone hemostasis material, which has the advantage of being "water soluble", meaning it will dissolve naturally over time. The purpose of this study is to evaluate how well Ostene does at decreasing bleeding, by using a recognized scale called the validated intraoperative bleeding severity scale, abbreviated as "VIBe". In this study, the investigators will record the bleeding severity throughout multiple time points in surgery using this scale, and then the investigators will compare the measurements to patients in the past who did not receive Ostene. Overall, this research will help measure how well Ostene decreases bleeding.
Blood transfusions are an important part of nursing procedure. Nurses play a key role in safely administering blood products to patients in surgical and critical care unit
Postoperative bleeding is still an important concern after major abdominal surgery. Postoperative bleeding is the most important determinant of morbidity and death. It results in longer hospital stays, the necessity for extra radiological tests, interventional radiology treatments, and the possibility of reoperation. Early detection of postoperative bleeding reduces morbidity and mortality with appropriate intervention.Simultaneous arterial and venous blood gas measurements can be used to quickly identify the degree of bleeding and the need for replacement in serious trauma patients brought to the emergency room.Lactate levels, venous oxygen saturation, and the differential in partial pressure of carbon dioxide between arterial and venous blood can all be used to indicate the requirement for replacement, as demonstrated in several studies. The purpose of this study is to evaluate lactate levels, venous oxygen saturation, and arterial-venous partial pressure of carbon dioxide difference in blood gas analysis in order to assess the severity of bleeding in patients undergoing major abdominal surgery as early as possible and perform replacement as soon as possible.
The strategy of the CoBAnK study is to establish and enable the function of Community-Facility Transfusion Committees (CFTCs) incorporating diverse representation involving hospital, community, and county leadership, to improve blood availability and transfusion at the point-of-care.
In critically ill patients, optimized strategies for red blood cells transfusion (RBCT) are still controversial. Most recent guidelines suggest that clinical practice in ICU setting should follow a restrictive approach to RBCT (i.e., hemoglonim level < 7.0 g/dL).In our previous study, oxygen extraction ratio (O2ER) has shown good performance as a marker to identify the correct timing for RBCT, potentially affecting 90-day mortality in non-bleeding, critically ill patients [11]. Moreover, our data suggested that an individualized strategy for RBCT may reduce the incidence of acute kidney injury (AKI), which is possibly related to a better delivery of oxygen and organ perfusion.
Evaluating the differences between D2 and D3 lymphadenectomy in laparoscopic right hemicolectomy in patients with right cancer colon post-operative outcome, intra-operative blood transfusion, post-operative ICU admission, anastomotic leakage, lymph node harvesting in the final specimen, and six months follow up and overall survival time after 5-years
Blood collected from blood donors is routinely divided into its different components, red blood cells, plasma and platelets. These components are stored under different storage conditions and their maximum storage time before transfusion is different. Platelets are stored at a maximum of 7 days and at a temperature of 22°C to best preserve their function. Research has been conduction on blood stored and transfused as whole blood (without separation into the various components), particularly in situations of acute trauma. Region Örebro län will therefore start transfusion of whole blood in such situations. The whole blood units will be stored at 4°C for a maximum of 14 days. This means that the platelets will be stored at a lower temperature than standard and for a longer time period. The research on how this will affect platelet function is limited. This project aims to determine how the patients are affected regarding coagulation, hemolysis, renal function, immunisation, transfusion reactions and the effect of substances released from the blood cells in the whole blood units during the storage period and if there is an impact on mortality.
Tranexamic acid is a medication used to treat or prevent excessive blood loss during surgery. Previous studies have shown tranexamic acid (TXA) reduces blood loss and post-operative blood transfusion rate without significant complications. In addition, many meta-analyses have confirmed these results. This study also aims to determine how safe and effective tranexamic acid treatment is for different patients undergoing primary total knee arthroplasty.
The investigators aimed to compare two doses of intravenous (IV) tranexamic acid (TXA) with a combined single dose of topical and IV TXA on haemoglobin decline 24 hours after total joint arthroplasties. The investigators conducted randomized, double-blind trial. The participants were randomized to either intrvenous group receiving 2 doses of 1 gram TXA in intravenous route 3 hours apart, or a combined application group receiving the first 1 gram IV and the topical dose was 1.5 gram after reduction of the fascia.
Tranexamic acid has been used to reduce bleeding and transfusion for years. Randomized studies showed its efficacity in orthopedic surgery, trauma and post-partum hemorrhage. Few data were available for other types of surgery and the safety profile of tranexamic use was nor clearly established. In april 2022, the results from the POISE-3 (Perioperative Ischemic Evaluation - 3) trial was published in the New England Journal of Medicine. This stdy clearly demonstrated in 9535 patients undergoing non-cardiac surgery, that the use of tranexamic acid significantly reduced not only perioperative bleeding, but also transfusions. The safety profile of tranexamic acid was very good in this trial. This publication was rapidly followed by editorials in major anesthesia journals, calling for "safe surgery" with a systematic use of tranexamic acid in the population studied in the POISE-3 trial. A literature review was done with a formal presentation at Erasme University Hospital, again with the call for a systematic use in appropriate patients. In this study, the adherence to these recommendations will be tested. All patients operated between october 1st 2022 and december 31 st 2022 will be included. For every patient, it will be determined if this patient should have received tranexamic acid according to the results of the POISE-3 trial and wether this patient really did get tranexamic acid. Primary endpoint will be the percentage (%) of patients correctly treated according to the POISE-3 recommendations. A second primary endpoint will be the comparison with patients operated between October 1st 2021 and december 31st 2021; that means before the publication of the recommendations. The difference between both populations will be tested with a Chi-square test. Secondary outcomes wil be bleeding and transfusion in the correctly treated population compared with an eventually not correctly treated population.
