Minimizing Blood Loss and Transfusions in Total Knee Arthroplasty

J Knee Surg DOI: 10.1055/s-0038-1648223Blood loss management is critical to positive outcomes in patients undergoing total knee arthroplasty (TKA). Transfusions are associated with an increased risk of major and minor adverse events, length of hospitalization, and overall cost associated with surgery. Many techniques have been investigated and compared. Tranexamic acid (TXA), an antifibrinolytic drug widely known to reduce blood loss, may be a bridge to the goal of eliminating blood transfusions from TKA. Administration of TXA can be performed intravenously, topically at the knee joint, orally, or in combination. A single bolus or multiple doses have reduced total blood loss and transfusion rates consistently, safely, and cost-effectively. The uptake in use of TXA by surgeons has been slow due to concerns in patients deemed high risk for thromboembolic events. Newer evidence from studies specifically involving high-risk patients demonstrates that TXA is indeed safe in this cohort and provides benefits that greatly outweigh potential risks. Incorporation of TXA as a routine part of TKA is in the best interest of patients, health care teams, and medical institutions. TXA can be employed seamlessly with other blood saving techniques and has the capacity to increase productivity and decrease overall cost. This can be achieved by reducing the incidence of transfusion and length of stay, and the need for practices such as preoperative anemia treatment and suction drainage. [...] Th...

Abstract BACKGROUND: Red blood cell distribution width (RDW) is a measure of anisocytosis, generally used in the differential diagnosis of anemia. Recently, RDW was associated with increased mortality in critically ill patients. Red blood cell (RBC) transfusions are potential confounders on RDW values interpretation. The aim of this study was to analyze the changes in RDW after RBC transfusion in intensive care unit (ICU) patients. STUDY DESIGN AND METHODS: This was a prospective, observational study including patients admitted to ICU requiring 1 RBC unit. We analyzed RDW values of the patients at four study ...

Shagun Bhatia Shah, Ajay Kumar Bhargava, Rajiv Chawla, Amardeep PathakIndian Journal of Anaesthesia 2018 62(5):385-388 Kidd blood group alloimmunisation, though extremely rare, may produce considerable morbidity, and even mortality. Severe anaemia and impending high-output cardiac failure requiring blood transfusion should be weighed against the risk of severe transfusion reactions even with fully cross-matched blood. Kidd antibodies are a common cause of delayed haemolytic transfusion reaction (DHTR) since they have a tendency remain undetectable in plasma. A low -grade DHTR (second hit) was grossly amplified by a second...

CONCLUSION: Despite recommendations by the American College of Obstetricians and Gynecologists for more than 15 years, fewer than 20% of postpubertal girls and adolescents with heavy menstrual bleeding underwent screening for von Willebrand disease in this cohort. Increased clinician awareness and adherence to recommended screening recommendations may increase diagnosis of von Willebrand disease. PMID: 29742662 [PubMed - as supplied by publisher]

This study revealed that post-surgical haemoglobin level of between 8 g/dl and 10 g/dL did not have an impact on the total length of hospital stay. The development of postoperative medical complications was the only factor that prolonged the total length of stay. PMID: 29734830 [PubMed - as supplied by publisher]

CONCLUSION: The nadir of absolute lymphocyte concentrations is an independent predictor of overall survival and progression free survival. This is an easily measurable biomarker which can be utilized for identifying patients that will be likely to respond to immunomodulation. Furthermore, this evidence showing significant improvement in OS and PFS with two or less cycles with hemoglobin

AbstractBackgroundAnaemia among haemodialysis patients is treated with iron and erythropoietin-stimulating agents (ESAs). ESAs reduce requirements for blood transfusions but are also expensive and overzealous use may be associated with adverse outcomes. Recent international trends have been characterised by reduced ESA doses and a greater reliance on intravenous (IV) iron. We determined trends in prescribing patterns of ESAs and IV iron for the treatment of anaemia in two representative Irish dialysis centres and correlated with current guidelines and international trends.MethodsPatient data was accessed from the Kidney Di...

Iron overload (IOL) due to transfusion-dependent anemia is a serious adverse effect in patients with myelofibrosis (MF). Recent studies have shown that the oral iron chelator deferasirox may prevent multiple organ damage due to IOL in MF. However, it is not clear whether deferasirox may contribute to revert transfusion-dependent anemia. Here, we present a patient with transfusion-dependent intermediate-2 MF according to the International Prognostic Scoring System treated with ruxolitinib in combination with deferasirox. In addition to a reduced serum ferritin level, the patient required less blood transfusions, ultimately ...

AbstractIron overload cardiomyopathy (IOC) is a major cause of death in patients with diseases associated with chronic anemia such as thalassemia or sickle cell disease after chronic blood transfusions. Associated with iron overload conditions, there is excess free iron that enters cardiomyocytes through both L- and T-type calcium channels thereby resulting in increased reactive oxygen species being generated via Haber-Weiss and Fenton reactions. It is thought that an increase in reactive oxygen species contributes to high morbidity and mortality rates. Recent studies have, however, suggested that it is iron overload in mi...
