Abstract
Blood transfusions are commonly viewed as life-saving interventions; however, current evidence shows that blood transfusions are associated with a significant increase of morbidity and mortality in a dose-dependent relationship. Not only explanatory models of basic research but also the results from randomized controlled trials suggest a causal relationship between blood transfusion and adverse outcome. Therefore, it can be claimed that the current state of science debunks the long held belief in the so-called life-saving blood transfusion by exposing the potential for promoting disease and death. Adherence to the precautionary principle and also the fact that blood transfusions are more costly than previously assumed require novel approaches in the treatment of anemia and bleeding. Patient Blood Management (PBM) allows transfusion rates to be dramatically reduced through correcting anemia by stimulating erythropoiesis, minimization of perioperative blood loss and harnessing and optimizing the physiological tolerance of anemia. A resolution of the World Health Assembly has endorsed PBM and therefore morbidity and mortality should be significantly reduced by lowering of the currently high blood utilization rate of allogeneic blood products in Austria, Germany and Switzerland.

Abstract
INTRODUCTION Hip and knee arthroplasties are frequently complicated by the need for allogeneic blood transfusions. This survey was conducted to assess the current use of perioperative blood-saving measures and to compare it with prior results. MATERIALS AND METHODS All departments of orthopaedic surgery at Dutch hospitals were sent a follow-up survey on perioperative blood-saving measures, and data were compared to the results of two surveys conducted 5 and 10 years earlier. RESULTS The response rate was 94 out of 108 departments (87%). Most departments used erythropoietin prior to hip and knee replacements at the expense of preoperative autologous blood donation. The use of intraoperative autologous retransfusion in revision hip (56 vs. 54%) as well as revision knee arthroplasty (26 vs. 24%), was virtually unchanged. Postoperative autologous retransfusion is still used by the majority of departments after both primary arthroplasty and revision of hip (58/53%) and knee (65/61%). CONCLUSIONS Currently, just as in 2007, the majority of Dutch orthopaedic departments uses erythropoietin, normothermia and postoperative autologous retransfusion with hip and knee arthroplasty. Intraoperative retransfusion is used mainly with hip revision arthroplasty. Other effective blood management modalities such as tranexamic acid have not been widely implemented.

Favourable results of a new intraoperative and postoperative filtered autologous blood re-transfusion system in total hip arthroplasty: a randomised controlled trial.

Abstract
PURPOSE A new intraoperative filtered salvaged blood re-transfusion system has been developed for primary total hip arthroplasty (THA) that filters and re-transfuses the blood that is lost during THA. This system is intended to increase postoperative haemoglobin (Hb) levels, reduce perioperative net blood loss and reduce the need for allogeneic transfusions. It supposedly does not have the disadvantages of intraoperative cell-washing/separating re-transfusion systems, such as extensive procedure, high costs and need for specialised personnel. To re-transfuse as much as blood as possible, postoperatively drained blood was also re-transfused. METHODS A randomised, controlled, blinded, single-centre trial was conducted in which 118 THA patients were randomised to an intraoperative autologous blood re-transfusion (ABT) filter system combined with a postoperative ABT filter unit or high-vacuum closed-suction drainage. RESULTS On average, 577 ml of blood was re-transfused in the ABT group: 323 ml collected intraoperatively and 254 ml collected postoperatively. Hb level was higher in the ABT vs the high-vacuum drainage group: 11.4 vs. 10.8 g/dl, p = 0.02 on day one (primary endpoint) and 11.0 vs. 10.4 g/dl, p = 0.007 on day three. Total blood loss was less in the autotransfusion group: 1472 vs. 1678 ml, p = 0.03. Allogeneic transfusions were needed in 3.6 % of patients in the ABT group and 6.5 % in the drainage group, p = 0.68. CONCLUSION The use of a new intraoperative ABT filter system combined with a postoperative ABT unit resulted in higher postoperative Hb levels and less total blood loss compared with a high-vacuum drain following THA.

Abstract
BACKGROUND Although a number of prohemostatic agents that are applied intraoperatively have been introduced to minimize bleeding, little is known about the patterns of use and the factors that influence use. We examined the use of hemostatic agents in patients undergoing major surgery. METHODS All patients who underwent major general, gynecologic, urologic, cardiothoracic, or orthopedic surgery from 2000-2010 who were recorded in the Perspective database were analyzed. RESULTS Among 3,633,799 patients, hemostatic agents were used in 30.3% (n = 1,102,267). The use of hemostatic agents increased from 28.5% in 2000 to 35.2% in 2010. Over the same period, the rates of transfusion declined for pancreatectomy (-14.4%), liver resection (-15.0%), gastrectomy (-11.7%), prostatectomy (-6.6%), nephrectomy (-4.6%), hip arthroplasty (-10.4%), and knee arthroplasty (-6.6%). Over the same time period, the transfusion rate increased for colectomy (6.0%), hysterectomy (3.7%), coronary artery bypass graft (8.4%), valvuloplasty (4.2%), lung resection (1.9%), and spine surgery (1.6%). Transfusion remained relatively stable for thyroidectomy (0.2%). CONCLUSIONS The use of hemostatic agents has increased rapidly even for surgeries associated with a small risk of transfusion and bleeding complications. In addition to patient characteristics, surgeon and hospital factors exerted substantial influence on the allocation of hemostatic agents.

Abstract
A 35-year-old man was scheduled for dural arteriovenous fistula resection for vascular malformation under general anesthesia and a cell saver device was employed. The patient suffered from massive bleeding for the rupture of arteriovenous malformations from the beginning of the operation and 1000 mL cell-saved blood was transfused. After autologous blood transfusion and fluid resuscitation, blood oozed significantly from the surgical wounds, and the administration of cryoprecipitate and fibrinogen has no effect. The value of the activated coagulation time (ACT) increased to 999s. Considering the residual heparin in the autologous blood, ninety mg of protamine was intravenously injected, then 5 minutes later the ACT dropped to 147s. After the therapy, the surgical procedure was performed smoothly. The activated partial thromboplastin time (APTT) and the thrombin time (TT) of the postoperative venous blood was 18.9 s and 53.6 s respectively. Two days later, the APTT and the TT decreased to 12.1 s and 32.7 s without special treatment. The patient was discharged home without complications and well follow-up.

Abstract
Cardiac surgery-associated acute kidney injury (CSA-AKI) is a common and serious postoperative complication of cardiac surgery requiring cardiopulmonary bypass (CPB), and it is the second most common cause of AKI in the intensive care unit. Although the complication has been associated with the use of CPB, the etiology is likely multifactorial and related to intraoperative and early postoperative management including pharmacologic therapy. To date, very little evidence from randomized trials supporting specific interventions to protect from or prevent AKI in broad cardiac surgery populations has been found. The definition of AKI employed by investigators influences not only the incidence of CSA-AKI, but also the identification of risk variables. The advent of novel biomarkers of kidney injury has the potential to facilitate the subclinical diagnosis of CSA-AKI, the assessment of its severity and prognosis, and the early institution of interventions to prevent or reduce kidney damage. Further studies are needed to determine how to optimize cardiac surgical procedures, CPB parameters, and intraoperative and early postoperative blood pressure and renal blood flow to reduce the risk of CSA-AKI. No pharmacologic strategy has demonstrated clear efficacy in the prevention of CSA-AKI; however, some agents, such as the natriuretic peptide nesiritide and the dopamine agonist fenoldopam, have shown promising results in renoprotection. It remains unclear whether CSA-AKI patients can benefit from the early institution of such pharmacologic agents or the early initiation of renal replacement therapy.

Do we really need tranexamic acid in total hip arthroplasty? A meta-analysis of nineteen randomized controlled trials. Arch Orthop Trauma Surg 2013; 133:1017-27.

Abstract
BACKGROUND Studies have shown that tranexamic acid reduces blood loss and transfusion need in patients undergoing total hip arthroplasty. However, no to date, no study has been large enough to determine definitively whether the drug is safe and effective. We examined whether intravenous tranexamic acid, when compared with placebo, was safe and effective in total hip arthroplasty. METHODS The literature search was conducted using the PubMed, Cochrane Library, MEDLINE, EMBASE, and China National Knowledge Infrastructure (CNKI) databases. Data were evaluated using the generic evaluation tool designed by the Cochrane Bone, Joint and Muscle Trauma Group. Ultimately, 19 randomized controlled trials involving 1,030 patients were included. RESULTS The use of tranexamic acid significantly reduced total blood loss by a mean of 305.27 mL [95 % confidence interval (CI) -397.66 to -212.89, p < 0.001], intraoperative blood loss by a mean of 86.33 mL(95 % CI -152.29 to -20.37, p = 0.01), postoperative blood loss by a mean of 176.79 mL (95 % CI -236.78 to -116.39, p < 0.001), and "hidden" blood loss by a mean of 152.70 mL (95 % CI -187.98 to -117.42, p < 0.001), resulting in a meaningful reduction in the proportion of patients requiring blood transfusion (odds ratio 0.28, 95 % CI 0.19 to 0.42, p < 0.001). There was no significant difference in occurrence of deep vein thrombosis, pulmonary embolism, or other complications among the study groups, or cost or hospitalization duration. CONCLUSIONS The data from this meta-analysis indicate that intravenous tranexamic acid may reduce blood loss and transfusion need in patients undergoing total hip arthroplasty without increasing the risk of complications. However, high-quality randomized controlled trials are required to validate the results.

Abstract
BACKGROUND There is concern that salvaged blood has the potential to activate the coagulation system, which might place patients at risk of thrombotic complications. The aim of this study was to determine whether transfusion of salvaged blood after total knee arthroplasty (TKA) would lead to procoagulopathic changes as measured by thromboelastography (TEG) and furthermore if washing would reduce this risk. STUDY DESIGN AND METHODS Twenty-two patients undergoing TKA were enrolled. Control samples were venous blood samples taken before surgery. Test samples were created by mixing the control samples with postoperatively salvaged blood, either washed or unwashed. TEG profiles were measured, noting the time to initiate clotting (R), the time of clot formation (K), the angle of clot formation (α-angle), and the maximum amplitude (clot strength [MA]). RESULTS The changes in the coagulation profile from control samples to test samples were consistent for both the washed and the unwashed groups: R time decreased, MA decreased, and K and α-angle remained the same. However, the changes were more pronounced in the unwashed group than the washed group, with a 61% decrease in R time compared with 14%, and a 26% decrease in MA compared with 6%. CONCLUSION The addition of salvaged blood to the patient's preoperative blood resulted in decreased MA as well as decreased R time. This suggests that the reinfusion of postoperatively salvaged washed or unwashed blood after TKA favors a change toward a more hypocoagulable state, and washing appears to reduce this effect.

Abstract
SUMMARYAutologous transfusion was first performed in the late 1800s, but it was not until the 1970s that devices were developed that enabled widespread adoption of the practice. Unwashed salvaged blood contains thrombogenic products, cell breakdown products and plasma proteins, and gross chemical, cellular and physical contaminants. Washing and filtering of salvaged blood is routinely performed to remove or reduce these elements. In this paper we review the clinical data supporting the need for washing and filtering of salvaged blood.

Abstract
PURPOSE Postoperative maintenance of high haemoglobin (Hb) levels and avoidance of homologous blood transfusions is important in total hip arthroplasty (THA). The introduction of a postoperative drainage autologous blood transfusion (ABT) system or no drainage following THA has resulted in reduction of homologous blood transfusion requirements compared with closed-suction drains. The purpose of this study was to examine which regimen is superior following THA. METHODS A randomised controlled blinded prospective single-centre study was conducted in which 100 THA patients were randomly allocated to ABT or no drainage. The primary endpoint was the Hb level on the first postoperative day. RESULTS The postoperative collected drained blood loss was 274 (±154) ml in the ABT group, of which 129 (±119) ml was retransfused (0-400). There was no statistical difference in Hb levels on the first postoperative day (ABT vs no drainage: Hb 11.0 vs 10.9 g/dl), on consecutive days (day 3: Hb 10.7 vs 10.2, p = 0.08) or in total blood loss (1,506 vs 1,633 ml), homologous transfusions, pain scores, Harris Hip Score, SF-36 scores, length of hospital stay or adverse events. CONCLUSIONS The use of a postoperative autologous blood retransfusion drain did not result in significantly higher postoperative Hb levels or in less total blood loss or fewer homologous blood transfusions compared with no drain.

Abstract
BACKGROUND There are risks related to blood incompatibility and blood-borne diseases when using allogeneic blood transfusion. Several alternatives exist today, one of which, used for autologous blood salvage perioperatively, is the Sangvia Blood Management System. This study was designed to investigate the efficacy of the system and to add data to previously reported safety results. METHODOLOGY/PRINCIPAL FINDINGS Two hundred sixteen patients undergoing primary or revision total hip arthroplasty (THA) were enrolled in this randomized, controlled, assessor-blinded multicenter study. Randomization was either autologous blood transfusion (Sangvia group) or no use of autologous blood (Control group), both in combination with a transfusion protocol for allogeneic transfusion. Patients were followed during hospital stay and at two months after discharge. The primary outcome was allogeneic blood transfusion frequency. Data on blood loss, postoperative hemoglobin/hematocrit, safety and quality of life were also collected. The effectiveness analysis including all patients showed an allogeneic blood transfusion rate of 14% in both groups. The efficacy analysis included 197 patients and showed a transfusion rate of 9% in the Sangvia group as compared to 13% in the Control group (95%CI -0.05-0.12, p = 0.5016). A mean of 522 mL autologous blood was returned in the Sangvia group and lower calculated blood loss was seen. 1095 mL vs 1285 mL in the Control group (95%CI 31-346, p = 0.0175). No differences in postoperative hemoglobin was detected but a lower hematocrit reduction after surgery was seen among patients receiving autologous blood. No relevant differences were found for safety parameters or quality of life. CONCLUSIONS/SIGNIFICANCE General low use of allogeneic blood in THA is seen in the current study of the Sangvia system used together with a transfusion protocol. The trial setting is under-powered due to premature termination and therefore not able to verify efficacy for the system itself but contributes with descriptive data on safety. TRIAL REGISTRATION Clinicaltrials.gov NCT00822588.

Abstract
BACKGROUND The increasing costs, limited supply, and clinical risks associated with allogeneic blood transfusion have prompted investigation into autologous blood management strategies, such as postoperative red blood cell (RBC) salvage. This study provides a cost comparison of transfusing washed postoperatively salvaged RBCs using an orthopedic perioperative autotransfusion device (OrthoPat, Haemonetics Corporation) versus unwashed shed blood and banked allogeneic blood. STUDY DESIGN AND METHODS Cell salvage data were retrospectively reviewed for a sample of 392 patients who underwent primary hip or knee arthroplasty. Mean unit costs were calculated for washed salvaged RBCs, equivalent units of unwashed shed blood, and therapeutically equivalent volumes of allogeneic RBCs. RESULTS No initial capital investment was required for the establishment of the postoperative cell salvage program. For patients undergoing total knee arthroplasty (TKA), the mean unit costs for washed postoperatively salvaged cells, unwashed shed blood, and allogeneic banked blood were $758.80, $474.95, and $765.49, respectively. In patients undergoing total hip arthroplasty (THA), the mean unit costs for washed postoperatively salvaged cells, unwashed shed blood, and allogeneic banked blood were $1827.41, $1167.41, and $2609.44, respectively. CONCLUSION This analysis suggests that transfusing washed postoperatively salvaged cells using the OrthoPat device is more costly than using unwashed shed blood in both THA and TKA. When compared to allogeneic transfusion, washed postoperatively salvaged cells carry a comparable cost in TKA, but potentially represent a significant savings in patients undergoing THA. Sensitivity analysis suggests that in the case of TKA, however, cost comparability exists within a narrow range of units collected and infused.

Abstract
PURPOSE A primary operative complication of radical hysterectomy for cervical cancer is hemorrhage. Intraoperative autologous blood transfusion (ABT) may be beneficial in reducing the need for homologous blood transfusion. METHODS Our institution published a prospective cohort study examining the use of ABT in cervical cancer patients undergoing radical hysterectomy in 1995. Patients who were initially consented to participate in this prospective trial using intraoperative ABT (cell saver) were evaluated with a median follow-up of 3 years. We sought to update this original report with 16-year follow-up data collected from the clinical charts, Tumor Registry, and the Social Security Death Index. RESULTS Two groups of patients undergoing radical hysterectomy were compared: patients who received ABT, and those who did not. Of the 71 original patients, all were included in this updated review, with an average follow-up of 12.4 years for both groups. Originally, thirty-one patients received an ABT. In this group, 1 patient was lost to follow-up, and 4 (12.9 %) are deceased including 1 (3 %) with disease. In the non-autologous group, there were 7 (17.5 %) patient deaths, including 3 (7.5 %) with disease. Eighty-three percent were alive after 12 years in both groups. The ABT group had 1 patient (3 %) who developed a secondary malignancy, a colon adenocarcinoma. The non-autologous group had 2 patients (5 %) who developed a secondary malignancy; one patient developed multiple myeloma and one patient developed a verrucous cancer of the tongue. CONCLUSIONS Autologous blood transfusion during radical hysterectomy for cervical cancer appears safe and effective.

Abstract
BACKGROUND Most clinical practice guidelines recommend restrictive red cell transfusion practices, with the goal of minimising exposure to allogeneic blood. The purpose of this review is to compare clinical outcomes in patients randomised to restrictive versus liberal transfusion thresholds (triggers). OBJECTIVES To examine the evidence for the effect of transfusion thresholds on the use of allogeneic and/or autologous red cell transfusion, and the evidence for any effect on clinical outcomes. SEARCH METHODS We identified trials by searching; The Cochrane Injuries Group Specialised Register (searched 01 Feb 2011), Cochrane Central Register of Controlled Trials 2011, issue 1 (The Cochrane Library), MEDLINE (Ovid) 1948 to January Week 3 2011, EMBASE (Ovid) 1980 to 2011 (Week 04), ISI Web of Science: Science Citation Index Expanded (1970 to Feb 2011), ISI Web of Science: Conference Proceedings Citation Index- Science (1990 to Feb 2011). We checked reference lists of other published reviews and relevant papers to identify any additional trials. SELECTION CRITERIA Controlled trials in which patients were randomised to an intervention group or to a control group. Trials were included where intervention groups were assigned on the basis of a clear transfusion 'trigger', described as a haemoglobin (Hb) or haematocrit (Hct) level below which a red blood cell (RBC) transfusion was to be administered. DATA COLLECTION AND ANALYSIS Risk ratios of requiring allogeneic blood transfusion, transfused blood volumes and other clinical outcomes were pooled across trials, using a random effects model. Data extraction and assessment of the risk of bias was performed by two people. MAIN RESULTS Nineteen trials involving a total of 6264 patients were identified, and were similar enough that the results could be combined. Restrictive transfusion strategies reduced the risk of receiving a RBC transfusion by 39% (RR 0.61, 95% CI 0.52 to 0.72). This equates to an average absolute risk reduction (ARR) of 34% (95% CI 24% to 45%). The volume of RBCs transfused was reduced on average by 1.19 units (95% CI 0.53 to 1.85 units). However, heterogeneity between trials was statistically significant (P<0.00001; I(2)≥93%) for these outcomes. Restrictive transfusion strategies did not appear to impact the rate of adverse events compared to liberal transfusion strategies (i.e. mortality, cardiac events, myocardial infarction, stroke, pneumonia and thromboembolism). Restrictive transfusion strategies were associated with a statistically significant reduction in hospital mortality (RR 0.77, 95% CI 0.62-0.95) but not 30 day mortality (RR 0.85, 95% CI 0.70 to 1.03). The use of restrictive transfusion strategies did not reduce functional recovery, hospital or intensive care length of stay. The majority of patients randomised were included in good quality trials, but some items of methodological quality were unclear. There are no trials in patients with acute coronary syndrome. AUTHORS' CONCLUSIONS The existing evidence supports the use of restrictive transfusion triggers in most patients including those with pre-existing cardiovascular disease. As there are no trials, the effects of restrictive transfusion triggers in high risk groups such as acute coronary syndrome need to be tested in further large clinical trials. In countries with inadequate screening of donor blood, the data may constitute a stronger basis for avoiding transfusion with allogeneic red cells.

Abstract
Patient Blood Management (PBM) describes an evidence-based, multidisciplinary therapeutic approach. Its focus is on the treatment of the individual patient and as such comprises transfusion therapy and pharmacotherapy. Furthermore, the applicability of PBM is not limited to the perioperative setting but is applicable also to other therapeutic measures and disciplines where significant blood loss is known to occur and where transfusion of blood products is part of the established treatment. PBM is fundamentally based on 3 pillars: (1) optimization of the (preoperative) erythrocyte volume, (2) reduction of diagnostic, therapeutic, or intraoperative blood loss, and (3) increasing individual tolerance towards anemia and accurate blood transfusion triggers. PBM primarily identifies patients at risk of transfusion and provides a management plan aimed at reducing or eliminating the risk of anemia and the need for allogeneic transfusion, thus reducing the inherent risks, inventory pressures, and the escalating costs associated with transfusion.

Abstract
BACKGROUND Revision hip arthroplasty (RHA) is associated with high rates of allogeneic blood transfusion (ABT). We aimed to determine factors associated with ABT in patients undergoing RHA in Scottish hospitals, with particular focus on perioperative cell salvage (PCS). METHODS A prospective observational cohort study of RHA procedures performed in 11 hospitals over 7 months was performed. We recorded predefined patient, surgery-related, and blood conservation factors that may influence perioperative ABT, together with postoperative haemoglobin (Hb) data and ABTs to day 7. We explored factors with strongest independent association with ABT during the perioperative period using multiple regression analysis. RESULTS Two hundred and ten cases were studied, of whom 58% received ABTs (mean 1.8 units), most of which (52%) occurred on the day of surgery. Eighty-eight (42%) patients received PCS, of whom 68 had red cells re-infused [mean re-infusion volume 312 ml (1st, 3rd quartile: 260, 363 ml)]. In unadjusted comparisons, patients receiving PCS had lower intraoperative (9% vs 40%) and total (55% vs 63%) exposure to ABTs. The mean (95% confidence interval) theatre blood loss was 1013 (899-1128) ml and was higher for combined femoral/acetabular revision and femoral revision than other categories. The mean postoperative Hb transfusion trigger was 80 g litre(-1). In multivariable models, preoperative Hb [odds ratio (OR) 0.35; P<0.001], patient weight (OR 0.96; P=0.004), operating theatre blood loss (OR 1.002; P<0.001), and re-infusion of PCS blood (OR 0.31; P=0.02) were independent predictors of ABT exposure. CONCLUSIONS PCS is an effective blood conservation strategy for RHA, especially for patients with preoperative anaemia, low body weight, or both.

Abstract
Although the safety of the blood supply has been greatly improved, there still remain both infectious and noninfectious risks to the patient. The incidence of noninfectious transfusion reactions is greater than that of infectious complications. Furthermore, the mortality associated with noninfectious risks is significantly higher. In fact, noninfectious risks account for 87-100% of fatal complications of transfusions. It is concerning to note that the majority of pediatric reports relate to human error such as overtransfusion and lack of knowledge of special requirements in the neonatal age group. The second most frequent category is acute transfusion reactions, majority of which are allergic in nature. It is estimated that the incidence of adverse outcome is 18:100,000 red blood cells issued for children aged less than 18 years and 37:100,000 for infants. The comparable adult incidence is 13:100,000. In order to decrease the risks associated with transfusion of blood products, various blood-conservation strategies can be utilized. Modalities such as acute normovolemic hemodilution, hypervolemic hemodilution, deliberate hypotension, antifibrinolytics, intraoperative blood salvage, and autologous blood donation are discussed and the pediatric literature is reviewed. A discussion of transfusion triggers, and algorithms as well as current research into alternatives to blood transfusions concludes this review.
