Perioperative anemia.
Perioperative anemia is common and is associated with increased need for blood transfusion in the perioperative period. Perioperative anemia has also been linked to increased morbidity and mortality in surgical patients. Anemia may impede a patient's ability to recover fully and participate in postoperative rehabilitation. Pre-operative treatment of anemia is associated with a reduction in the need for blood transfusion in the perioperative period. Additional advances in surgical technology that reduce blood loss intraoperatively are associated with a reduction in postoperative anemia and should be used whenever possible. All strategies to prevent anemia in the perioperative period should be considered in an effort to minimize exposure of surgical patients to blood transfusion.

Integrated analysis of thrombotic/vascular event occurrence in epoetin alfa-treated patients undergoing major, elective orthopedic surgery.
Data from four prospective, multicenter, randomized studies involving 869 major, elective orthopedic surgery patients were examined by means of a retrospective integrated analysis to evaluate whether perioperative Epoetin alfa use was associated with the occurrence of thrombotic/vascular events. The incidence of thrombotic/vascular events was similar between 619 patients treated with Epoetin alfa and 250 patients receiving placebo (7.4% versus 8.0%, respectively). Regression analyses identified age, cardiac history, hypertension, and cardiac medications, but not Epoetin alfa, as risk factors for thrombotic/vascular events. The analysis did not implicate an increase in the rate of rise in hematocrit or maximum hematocrit obtained prior to surgery as contributors to thrombotic events. Thus, Epoetin alfa, which enhances preoperative erythropoiesis and increases hematocrit, did not affect the probability of thrombotic/vascular events.

Epoetin alfa. A bloodless approach for the treatment of perioperative anemia.
Under normal physiologic conditions the level of circulating red blood cells is regulated precisely by the glycoprotein erythropoietin. In major elective surgery, patients who are participating in preoperative autologous blood donation or who are anemic may not have the capacity to manufacture sufficient red blood cells in response to increases in endogenous erythropoietin that is sufficient to avoid perioperative allogeneic blood transfusion. In these patients pharmacologic doses of recombinant human erythropoietin (Epoetin alfa) have been shown to accelerate erythropoiesis, thereby increasing preoperative red blood cell production, hematocrit level, and hemoglobin concentration and reducing exposure to allogeneic blood transfusion. In four large multicenter studies, 869 patients undergoing major elective surgery were treated with a daily regimen (300 or 100 IU/kg x 14 or 15 doses) or a weekly regimen (600 IU/kg x 4 doses) of subcutaneous Epoetin alfa beginning either 2 or 3 weeks before surgery, respectively. Although all Epoetin alfa regimens were effective at accelerating erythropoiesis and increasing red blood cell production, the weekly regimen was the most patient friendly, cost effective regimen for treating preoperative anemia and minimizing patient risk of allogeneic blood transfusion.

Preoperative Epoetin-α with Intravenous or Oral Iron for Major Orthopedic Surgery: A Randomized Controlled Trial.
WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Preoperative administration of epoetin-α with iron is commonly used in anemic patients undergoing major orthopedic surgery, but the optimal route of iron intake is controversial. The aim of this study was to compare the clinical effects of erythropoietin in combination with oral or intravenous iron supplementation.. This study was a prospective, randomized, single-blinded, parallel arm trial. Patients scheduled for elective hip or knee arthroplasty with hemoglobin 10 to 13 g/dl received preoperative injections of erythropoietin with oral ferrous sulfate or intravenous ferric carboxymaltose. The primary endpoint was the hemoglobin value the day before surgery.. One hundred patients were included in the analysis. The day before surgery, hemoglobin, increase in hemoglobin, and serum ferritin level were higher in the intravenous group. For the intravenous and oral groups, respectively, hemoglobin was as follows: median, 14.9 g/dl (interquartile range, 14.1 to 15.6) versus 13.9 g/dl (interquartile range, 13.2 to 15.1), group difference, 0.65 g/dl (95% CI, 0.1 to 1.2; P = 0.017); increase in hemoglobin: 2.6 g/dl (interquartile range, 2.1 to 3.2) versus 1.9 g/dl (interquartile range, 1.4 to 2.5), group difference, 0.7 g/dl (95% CI, 0.3 to 1.1; P < 0.001); serum ferritin: 325 µg/l (interquartile range, 217 to 476) versus 64.5 µg/l (interquartile range, 44 to 107), group difference, 257 µg/l (95% CI, 199 to 315; P < 0.001). The percentage of patients with nausea, diarrhea, or constipation was higher in the oral group, 52% versus 2%; group difference, 50% (95% CI, 35 to 64%; P < 0.0001).. After preoperative administration of erythropoietin, body iron stores and stimulation of the erythropoiesis were greater with intravenous ferric carboxymaltose than with oral ferrous sulfate supplementation.

Effect of erythropoietin on the incidence of acute kidney injury following complex valvular heart surgery: a double blind, randomized clinical trial of efficacy and safety.
Recombinant human erythropoietin (EPO) is known to provide organ protection against ischemia-reperfusion injury through its pleiotropic properties. The aim of this single-site, randomized, case-controlled, and double-blind study was to investigate the effect of pre-emptive EPO administration on the incidence of postoperative acute kidney injury (AKI) in patients with risk factors for AKI undergoing complex valvular heart surgery.. We studied ninety-eight patients with preoperative risk factors for AKI. The patients were randomly allocated to either the EPO group (n = 49) or the control group (n = 49). The EPO group received 300 IU/kg of EPO intravenously after anesthetic induction. The control group received an equivalent volume of normal saline. AKI was defined as an increase in serum creatinine >0.3 mg/dl or >50% from baseline. Biomarkers of renal injury were serially measured until five days postoperatively.. Patient characteristics and operative data, including the duration of cardiopulmonary bypass, were similar between the two groups. Incidence of postoperative AKI (32.7% versus 34.7%, P = 0.831) and biomarkers of renal injury including cystatin C and neutrophil gelatinase-associated lipocalin showed no significant differences between the groups. The postoperative increase in interleukin-6 and myeloperoxidase was similar between the groups. None of the patients developed adverse complications related to EPO administration, including thromboembolic events, throughout the study period.. Intravenous administration of 300 IU/kg of EPO did not provide renal protection in patients who are at increased risk of developing AKI after undergoing complex valvular heart surgery..

Epoetin administrated after cardiac surgery: effects on renal function and inflammation in a randomized controlled study.
Experimentally, erythropoietin (EPO) has nephroprotective as well as immunomodulatory properties when administered after ischemic renal injury. We tested the hypothesis that different doses of recombinant human EPO administered to patients after cardiac surgery would minimize kidney lesions and the systemic inflammatory response, thereby decreasing acute kidney injury (AKI) incidence.. In this double-blinded randomized control study, 80 patients admitted to the ICU post-cardiac surgery were randomized by computer to receive intravenously isotonic saline (n = 40) versus α-Epoetin (n = 40): either 40000 IU (n = 20) or 20000 IU (n = 20). The study lasted one year. The primary outcome was the change in urinary NGAL concentration from baseline and 48 h after EPO injection. Creatinine, cystatine C and urinary NGAL levels were measured on the day of randomization and 2-4 days after EPO injection. To assess acute inflammatory response, serum cytokines (IL6 and IL8) were measured at randomization and four days after r-HuEPO injection. Patients and care-takers were blinded for the assignment.. No patient was excluded after randomization. Patient groups did not differ in terms of age, gender, comorbidities and renal function at randomization. The rate of AKI assessed by AKIN criteria was 22.5% in our population. EPO treatment did not significantly modify the difference in uNGAl between 48 hours and randomization compared to placebo [2.5 ng/ml (-17.3; 22.5) vs 0.7 ng/ml (-31.77; 25.15), p = 0.77] and the incidence of AKI was similar. Inflammatory cytokines levels were not influenced by EPO treatment. Mortality and hospital stays were similar between the groups and no adverse event was recorded.. In this randomized-controlled trial, α-Epoetin administrated after cardiac surgery, although safe, demonstrated neither nephroprotective nor anti-inflammatory properties.. NCT00676234.

Efficacy of preoperative recombinant human erythropoietin administration for reducing transfusion requirements in patients undergoing surgery for hip fracture repair. An observational cohort study.
Preoperative anaemia is a major risk factor for allogeneic blood transfusion (ABT) in patients undergoing hip fracture repair. We investigated the efficacy of preoperative recombinant human erythropoietin (rHuEPO) administration for reducing ABT requirements in a series of consecutive hip fracture patients presenting with haemoglobin (Hb) between 10 g/dl and 13 g/dl.. The blood conservation protocol consisted of the application of a restrictive transfusion trigger (Hb < 8 g/dl) and the perioperative administration of intravenous iron sucrose (3 x 200 mg/48 h) (group 1, n = 115). Additionally, some patients received preoperative rHuEPO (40 000 IU sc) on admission to the orthopaedic ward (group 2, n = 81).. Overall, 103 of 196 patients (52.5%) received at least one ABT unit (2.1 +/- 1.0 U/patient). However, there were significant differences in perioperative ABT rates between groups (60% vs. 42%, for groups 1 and 2, respectively; P = 0.013). Postoperative Hb on postoperative days 7 and 30 was higher in group 2 than in group 1. In addition, in group 2, Hb levels were higher on postoperative day 30 than on admission (12.7 +/- 1.0 g/dl vs. 11.9 +/- 0.8 g/dl, respectively; P = 0.030). Administration of rHuEPO did not increase postoperative complications or 30-day mortality rate. Only three mild intravenous iron adverse effects were witnessed.. In anaemic hip fracture patients managed with perioperative intravenous iron and restrictive transfusion protocol, preoperative administration of rHuEPO is associated with reduced ABT requirements. However, appropriate training, education and awareness are needed to avoid protocol violations and to limit further exposure to ABT and ABT-related risks.

Successful blood conservation during craniosynostotic correction with dual therapy using procrit and cell saver.
Craniosynostotic correction typically performed around infant physiologic nadir of hemoglobin (approximately 3-6 months of age) is associated with high transfusion rates of packed red blood cells and other blood products. As a blood conserving strategy, we studied the use of 1) recombinant human erythropoietin or Procrit (to optimize preoperative hematocrit) and 2) Cell Saver (to recycle the slow, constant ooze of blood during the prolonged case).. UCLA Patients with craniosynostosis from 2003-2005 were divided into 1) the study group (Procrit and Cell Saver) or 2) the control group (n = 79). The study group 1) received recombinant human erythropoietin at 3 weeks, 2 weeks, and 1 week preoperatively and 2) used Cell Saver intraoperatively. Outcomes were based on morbidities and transfusion rate comparisons.. The 2 groups were comparable with regards to age (5.66 and 5.71 months), and operative times (3.11 vs 2.59 hours). In the study group there was a marked increase in preoperative hematocrit (56.2%). The study group had significantly lower transfusions rates (5% vs 100% control group) and lower volumes transfused than in the control group (0.05 pediatric units vs 1.74 pediatric units). Additionally, of the 80% of patients in the study group who received Cell Saver blood at the end of the case, approximately 31% would have needed a transfusion if the recycled blood were unavailable.. Our data showed that for elective craniosynostotic correction, successful blood conserving dual therapy with Procrit and Cell Saver might be used to decrease transfusion rates and the need for any blood products.

A randomized, parallel-group, open-label trial of recombinant human erythropoietin vs preoperative autologous donation in primary total joint arthroplasty: effect on postoperative vigor and handgrip strength.
This randomized trial assessed the effect of recombinant human erythropoietin (EPO) vs preoperative autologous donation (PAD) on postoperative vigor and handgrip strength in patients undergoing primary total joint arthroplasty. Adults with baseline hemoglobin level of 11 to 14 g/dL received EPO (600 IU/kg once weekly for 4 doses, n = 130) or PAD (n = 121) before primary, unilateral hip or knee arthroplasty. Mean changes in vigor score and handgrip strength from baseline were not significantly different between treatment groups. Multivariate analyses found a significant treatment effect favoring EPO over PAD for vigor, but not for handgrip strength. Patients in the EPO group had higher hemoglobin levels and required fewer transfusions. Both treatments were well tolerated. Additional study is needed to elucidate the influence of blood management strategies on postoperative vigor.

Erythropoietin-alfa during neoadjuvant chemotherapy for locally advanced esophagogastric adenocarcinoma.
In a previous study we showed that many patients with esophagogastric adenocarcinoma experience anemia during neoadjuvant chemotherapy. We now investigated the role of erythropoietin in managing anemia during neoadjuvant chemotherapy.. Patients with esophagogastric adenocarcinoma who experienced anemia (hemoglobin < 12 g/dL) during neoadjuvant treatment received erythropoietin 10,000 IE subcutaneously three times a week. Primary outcomes were the response to erythropoietin, safety, the need for allogeneic red blood cell transfusion, and the rate of postoperative complications.. Between April 2003 and December 2004, 24 patients (median age, 62 years) were enrolled. The mean hemoglobin level before chemotherapy was 12.5 g/dL and the mean hemoglobin level before patients received erythropoietin was 11.5 g/dL. One year after involvement in the trial, 4 of 17 analyzable patients were still anemic (hemoglobin level < 12 mg/dL). Twenty-two patients received erythropoietin, and 16 (73%) responded. We could observe a significant increase in hemoglobin concentrations under therapy with erythropoietin to 12.6 g/dL (p < 0.001). Two patients (8%) received allogeneic transfusions; the rate of postoperative complications was 16%. There were no erythropoietin-related adverse events.. Treatment with erythropoietin is effective and well tolerated in patients with esophagogastric adenocarcinoma who experience anemia during neoadjuvant chemotherapy.

Patients with and without rheumatoid arthritis benefit equally from preoperative epoetin-alpha treatment.
Preoperative epoetin-alpha administration is said to have a limited effect in patients with chronic inflammatory diseases such as rheumatoid arthritis (RA), due to lower iron availability. We studied the effects of preoperative epoetin-alpha treatment in orthopedic surgery patients in a daily life setting in which iron supplementation was assured, and compared the effects in RA and non-RA patients.. In an open, naturalistic, randomized controlled trial, 695 orthopedic surgery patients with preoperative hemoglobin (Hb) values of 10-13 g/dL, either with RA (113) or without RA (582), received either preoperative epoetin-alpha treatment added to standard care, or standard care alone. Hb values and transfusions were evaluated from entry into the study until 4-6 weeks after surgery.. Both in RA and non-RA patients, perioperative Hb values were significantly higher and transfusion requirements were significantly lower in epoetin-alpha treated patients than in control patients (p < 0.001). In RA patients, the outcomes regarding Hb values were not significantly or relevantly different from non-RA patients.. Just as with orthopedic patients in general, RA patients benefit from preoperative epoetin-alpha treatment in combination with iron supplementation. We postulate that iron supplementation during epoetin-alpha therapy in RA patients is important for optimal efficacy.

[Anemia in patients with resectable tumour of periampullar zone organs as a risk factor of postoperative complications occurrence and its complex correction].
Results of treatment of 39 patients, to whom pancreatoduodenal resection was performed for periampullar zone tumour, were analyzed. Anemia, revealed before the operation, had constituted the factor, which trustworthily increased the postoperative complications occurrence risk. Therapeutic course, using recombinant erythropoietins, was conducted for correction of anemia in 7 patients. This had promoted the hemoglobin level raising, the risk of postoperative complications occurrence lowering, but did not influence the intraoperative blood loss severity and perioperative hemotransfusion volume.

Effects of epoetin alfa on blood transfusions and postoperative recovery in orthopaedic surgery: the European Epoetin Alfa Surgery Trial (EEST).
Preoperative epoetin alfa administration decreases transfusion requirements and may reduce transfusion complications, such as postoperative infection due to immune suppression and thus hospitalization time. This study examined the impact of preoperative epoetin alfa administration on postoperative recovery and infection rate.. In an open randomized controlled multicentre trial in patients undergoing orthopaedic surgery, the effects of preoperative administration of epoetin alfa vs. routine care were compared in six countries. Haemoglobin (Hb) values, transfusions, time to ambulation, time to discharge, infections and safety were evaluated in patients with preoperative Hb concentrations 10-13g dL(-1) (on-treatment population: epoetin n = 460; control n = 235), from study entry until 4-6 weeks after surgery. Outcome was also compared in patients with and without transfusion.. Epoetin-treated patients had higher Hb values from the day of surgery until discharge (P < 0.001) and lower transfusion rates (12% vs. 46%; P < 0.001). Epoetin treatment delivered no significant effect on postoperative recovery (time to ambulation, time to discharge and infection rate). However, the time to ambulation (3.8+/-4.0 vs. 3.1+/-2.2days; P < 0.001)and the time to discharge (12.9+/-6.4 vs. 10.2+/-5.0 days; P < 0.001) was longer in the transfused than in the non-transfused patients. Side-effects in both groups were comparable.. Epoetin alfa increases perioperative Hb concentration in mild-to-moderately anaemic patients and thus reduces transfusion requirements. Patients receiving blood transfusions require a longer hospitalization than non-transfused patients.

The effects of epoetin alfa on transfusion requirements in head and neck cancer patients: a prospective, randomized, placebo-controlled study.
To evaluate the efficacy of perioperative recombinant human erythropoietin (r-HuEPO, epoetin alfa) in stimulating hematopoiesis and reducing allogeneic blood transfusion requirements in major head and neck cancer surgery.. Double-blinded, placebo-controlled, randomized, prospective clinical trial.. Fifty-eight patients undergoing surgical resection of head and neck tumors at the University of Iowa hospitals completed this study. Patients were required to have a pre-study hemoglobin >/=10.0 g/dL and =13.5 g/dL. Group 1 (29 patients) received three doses of 600 IU/kg epoetin alfa before surgery. Group 2 (29 patients) received a placebo. All patients received oral iron supplementation (150 mg FeSO4 twice per day).. The epoetin alfa group demonstrated a significant increase in baseline to day-of-surgery mean hemoglobin (0.57 g/dL, P =.016), hematocrit (2.04%, P =.015), and reticulocyte count (95.3 x 103 cells/mm3, P = <.001), whereas there was no significant change in these hematologic variables in the placebo group. The percent of patients who avoided transfusion in the epoetin alfa group was 34.5% versus 17.2% in the placebo group. Patients requiring allogeneic blood transfusions received an average of 3.16 units in the epoetin alfa group and 4.12 units in the placebo group.. In this single institution study, we demonstrated a significant improvement in hematopoietic parameters and a trend toward decreased transfusion requirements using perioperative epoetin alfa in a head and neck cancer patient population. Further studies may delineate additional benefits in treating qualified patients with epoetin alfa during therapy for head and neck malignancies.

The use of Epoetin alfa in complex spine deformity surgery.
A prospective, randomized trial comparing Epoetin alfa (Procrit) with placebo saline injection to determine effectiveness in increasing erythropoietic recovery in complex spine deformity surgery.. To determine if Epoetin alfa can allow preoperative autologous donation completion more effectively and reduce perioperative homologous blood transfusion.. The use of Epoetin alfa has been studied, primarily in the arthroplasty literature, for its effectiveness in decreasing transfusion requirements and increasing hemoglobin levels. It has not been studied in patients undergoing complex spine deformity surgery.. A total of 48 patients were prospectively randomized into an Epoetin alfa group and a control group. All patients attempted to donate 4 units of preoperative autologous donation at weekly intervals; 40,000 units of Epoetin alfa were injected subcutaneously at the time of preoperative autologous donation in the Epoetin alfa group. Hematocrit levels were recorded weekly during the donation process and daily in the preoperative period.. Preoperative autologous donation was completed more effectively in the patients receiving Epoetin alfa. Epoetin alfa resulted in statistically higher hematocrit levels during preoperative autologous donation and perioperatively (P < 0.005). Homologous transfusion was decreased by 2.4 units and hospital stay was 1.8 days shorter in patients receiving Epoetin alfa.. Patients who received Epoetin alfa were able to complete preoperative autologous donation more effectively, increase erythropoietic recovery, decrease homologous transfusion requirements, and had shorter hospital stays.

An open-label, randomized study to compare the safety and efficacy of perioperative epoetin alfa with preoperative autologous blood donation in total joint arthroplasty.
A multicenter, randomized, open-label, parallel-group study was conducted to compare the safety and efficacy of perioperative recombinant human erythropoietin (Epoetin alfa) with the safety and efficacy of preoperative autologous donation (PAD) in total joint arthroplasty. A total of 490 patients scheduled for total joint (i.e., hip or knee) surgery and having hemoglobin (Hb) levels > or = 11 to < or = 13 g/dL were randomized to receive weekly doses of subcutaneous Epoetin alfa on preoperative Days -21, -14, and -7, and on the day of surgery, or to participate in a PAD program. The mean baseline Hb level in both groups was 12.3+/-0.6 g/dL, increasing to 13.8 g/dL in the Epoetin alfa-treated group and decreasing to 11.1 g/dL in the PAD group before or on the day of surgery. In the PAD group, 156/219 (71.2%) patients were transfused with autologous blood, and 42/219 (19.2%) patients were transfused with allogeneic blood. A smaller proportion, 27/209 (12.9%) patients, in the Epoetin alfa-treated group were transfused with allogeneic blood (P = .078 compared with the PAD group). Moreover, patients in the PAD group received a total of 325 units of blood (79 allogeneic units and 246 autologous units) compared with patients in the Epoetin alfa group who received a total of 54 units of blood. The mean postoperative Hb level was 11.0 g/dL in the Epoetin alfa-treated group and 9.2 g/dL in the PAD group. Compared with the PAD arm, mean Hb levels measured preoperatively, postoperatively on Day 1, and at discharge visits were significantly greater in the Epoetin alfa-treated arm (P < .0001 ).

Use of epoetin alfa in autologous blood donation programs for patients scheduled for elective cardiac surgery.
The optimum dosage of subcutaneous (s.c.) epoetin alfa was assessed in a double-blind study in 31 patients scheduled for cardiac surgery. Patients received a total of four doses of either epoetin alfa 150 IU/kg (n = 11), epoetin alfa 300 IU/kg (n = 10), or placebo (n = 10) administered as single s.c. injections at weekly intervals starting 23 days prior to surgery. AB was collected with isovolemic replacement prior to each of the first three doses of medication. During the AB donation period, Hb levels decreased significantly (P < .05) from baseline to surgery in the placebo group (16.5%), compared with no significant decrease in either of the epoetin alfa groups (8.1% and 9.7% in the 150 IU/kg and 300 IU/kg groups, respectively). In addition, the difference between groups with regard to the decrease in Hb level reached statistical significance (P < .05) for the 150 IU/kg group versus placebo. Epoetin alfa treatment was also associated with significantly higher reticulocyte counts and serum erythropoietin levels in the preoperative period compared with placebo.

Baseline hemoglobin as a predictor of risk of transfusion and response to Epoetin alfa in orthopedic surgery patients.
A multicenter, double-blind, placebo-controlled, parallel-group study was undertaken to determine whether Epoetin alfa can reduce perioperative transfusion requirements. Twenty-six medical centers enrolled 316 patients who were scheduled for major orthopedic surgery and were expected to require > or = 2 units of blood. Patients were stratified according to baseline hemoglobin levels and randomly assigned to receive either Epoetin alfa (300 IU/kg or 100 IU/kg) or placebo for 15 consecutive days starting 10 days prior to, on the day of, and for 4 days after surgery. Epoetin alfa (300 IU/kg) resulted in significantly less exposure to allogeneic blood transfusion compared with placebo (16%) versus 45%) in patients whose baseline hemoglobin level was > 10 to < or = 13 g/dL (P = 0.024). Mean number of units transfused per patient was also lower among those treated with Epoetin alfa (overall, P = 0.027). Epoetin alfa was safe and well tolerated in this population.

Impact of a blood management protocol on transfusion rates and outcomes following total hip and knee arthroplasty.
Introduction Preoperative anaemia remains undertreated in the UK despite advice from national agencies to implement blood conservation measures. A local retrospective audit of 717 primary hip/knee replacements in 2008-2009 revealed 25% of patients were anaemic preoperatively. These patients experienced significantly increased transfusion requirements and length of stay. We report the results of a simple and pragmatic blood management protocol in a district general hospital. Methods Since 2010 patients at our institution who are found to be anaemic when listed for hip/knee replacement have been offered iron supplementation and/or erythropoietin depending on haemoglobin and ferritin levels. In this study, postoperative blood transfusions, length of stay and readmissions were assessed retrospectively for all patients undergoing elective primary hip/knee replacement in 2014 and compared with the baseline findings. Results During the 12-month study period, 406 patients were eligible for inclusion and none were excluded. Eighty-nine patients (22%) were anaemic preoperatively and sixty-five received treatment. The transfusion rate fell from the baseline levels of 23.0% and 6.7% to 4.3% and 0.5% for hip and knee replacements respectively (p<0.001). The median length of stay reduced from 6 to 3 days (p<0.001) for both hip and knee replacements. The rate for readmissions within 90 days fell from 13.5% to 8.9% (p<0.05). Conclusions Preoperative anaemia is common in patients listed for hip/knee replacement and it is associated strongly with increased blood transfusion. The introduction of a blood management protocol has led to significant reductions in transfusion and length of stay, sustained over a four-year period. This suggests that improved patient outcomes, conservation of blood stocks and cost savings can be achieved.

ERYTHROPOIESIS AND RENAL HOMOTRANSPLANTATION.
Following the successful replacement of diseased kidneys by renal homotransplants, regression of the anemia of chronic renal disease was found in five patients. Increased erythropoietic-stimulating activity was demonstrated in the serum of one patient seven weeks after renal transplantation when he suffered a severe hemorrhage. It is postulated that a renal homotransplant can produce enough erythropoietin to maintain a normal hemoglobin value and to respond to the stimulus of a sudden hemorrhage.
