AIM: Major hepatic resection of a cirrhotic liver may result in a fatal clinical course. Preoperative erythropoietin (EPO) treatment has been shown to have protective properties and to stimulate liver regeneration. This study aims to investigate the effect of preoperative EPO on survival following major hepatic resection in a cirrhotic rat model. METHODS: Cirrhotic liver was induced by intraperitoneal injection of thioacetamide (200mg/kg/mL) in 72 Lewis rats. Each 36 rats received EPO (1IU/g, every second day, 5 times preoperatively) or saline (control) and major hepatectomy (removal of the left and half of the median lobe) was performed...

BACKGROUND: Erythropoiesis-stimulating agents, such as erythropoietin (EPO), can be used to treat preoperative anemia. Some studies suggest an increased risk of mortality and thrombotic events, and use in cardiovascular surgery remains off-label. This study compares outcomes in cardiac surgery patients declining blood transfusion who received EPO with a matched cohort who did not. METHODS: After institutional review board approval, we conducted a retrospective review of all patients who decline blood transfusion who underwent cardiac surgery and received EPO between January 1, 2004, and June 15, 2015, at a single institution...

Erythropoietin (EPO) is proposed preoperatively to reduce blood transfusion in anemic patients (hemoglobin < 13 g/dL) scheduled for a major orthopedic surgery. New intravenous iron formulations allow infusion of higher doses, increasing EPO response. In that context, we evaluated in a before-after study (n = 62 and 65 patients for each period) a new EPO administration protocol (2 injections 4 and 3 weeks before surgery, and a third if hemoglobin <13 g/dL instead of <15 g/dL 2 weeks before surgery)...

Successful deformity correction depends on establishing the aetiology of the deformity. Clinical examination, additional laboratory tests and consultation with other experts may be needed to complete the workup. Imaging studies should include full-length standing X-rays in all relevant planes, and additional imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI) may add information on bone morphology and growth plates' anatomy. Based on the data, analysis of the deformity and length differences is performed, followed by prediction of deformities at skeletal maturity...

BACKGROUND: The role of perioperative erythropoietin (EPO) for preventing cardiac surgery associated acute kidney injury (CSA-AKI) remains uncertain with published trials producing conflicting results. Perspective into the factors at work is needed, due to ongoing uncertainty. METHODS: We undertook the systematic review and meta-analysis of randomised-controlled trials (RCTs) using random-effects modelling. The primary outcome was safety and efficacy of perioperative EPO to prevent CSA-AKI and the secondary outcomes were change in serum creatinine, urinary neutrophil gelatinase-associated lipocalin, time in ICU, rates of postoperative transfusions, haemodialysis, and mortality...

BACKGROUND: The increasing incidence of osteoporotic hip fracture (HF) has raised the requirements of red blood cell (RBC) transfusions, whereas this scarce resource may cause morbidity and mortality. STUDY DESIGN AND METHODS: This study was a multicenter, randomized, double-blind, clinical trial that aimed to assess efficacy of ferric carboxymaltose (FCM) with or without erythropoietin (EPO) in reducing RBC transfusion in the perioperative period of HF. Participants (patients > 65 years admitted with HF and hemoglobin [Hb] levels of 90-120 g/L) were randomly assigned to receive a preoperative single dose of 1 g of FCM (short intravenous [IV] infusion over 15 min), plus 40,000 IU of subcutaneous EPO (EPOFE arm); versus 1 g of IV FCM plus subcutaneous placebo (FE arm); and versus IV and subcutaneous placebo (placebo arm)...

BACKGROUND: Patient blood management (PBM) must be promoted in orthopedic surgery and relies on different strategies implemented during the entire perioperative period. Our aim was to assess whether the introduction of a pre-, intra-, and postoperative PBM protocol combining erythropoietin (EPO), ferric carboxymaltose (FCM), and tranexamic acid was effective in reducing perioperative transfusion and postoperative anemia. STUDY DESIGN AND METHODS: In a two-phase prospective observational study, all patients admitted for total hip or knee arthroplasty were included the day before surgery...

BACKGROUND: Preoperative anemia is present in 20% of total joint arthroplasty patients. Current preoperative treatment options, including iron supplementation (FE) and erythropoietin (EPO), are expensive. Tranexamic acid (TXA) has been adopted as an intraoperative adjunct to decrease blood loss. Our hypothesis is that TXA is a cost-effective treatment compared to FE and EPO in anemic patients. METHODS: In this study, a cost analysis was performed, comparing the material costs of TXA and packed red blood cells (PRBCs) to the theoretical administration and material costs of FE and EPO per standard preoperative anemia protocol...
