Red Blood Cell Transfusion Requirements Before and After Implementation of a Perioperative Patient Blood Management Program in Adult Patients Undergoing Cardiac Surgery. A Before and After Observational Study. J Cardiothorac Vasc Anesth 2024; 38:73-79. [PMID: 37953174 DOI: 10.1053/j.jvca.2023.10.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 10/12/2023] [Accepted: 10/16/2023] [Indexed: 11/14/2023]
Abstract
OBJECTIVES Anemia and transfusion are common in cardiac surgery patients, and are associated with significant morbidity and mortality. Multiple perioperative interventions have been described to reduce blood transfusion, but are rarely combined altogether. The aim of this study was to compare the incidence of red blood cell (RBC) transfusion in adult patients undergoing cardiac surgery before and after the implementation of a perioperative patient blood management (PBM) program. DESIGN Before-and-after observational study. SETTING Single-center French university teaching hospital. PARTICIPANTS Adult patients scheduled for cardiac surgery. INTERVENTIONS Perioperative patient blood management program including pre-, intra-, and postoperative interventions aimed at identifying and correcting anemia, minimizing blood loss during surgery, and optimizing coagulation. MEASUREMENTS AND MAIN RESULTS Four hundred thirty-four patients were included in the study from January 2021 to July 2022. The incidence of perioperative RBC transfusion (intraoperatively and during the first 2 postoperative days) was significantly reduced from 43% (90/213) in the pre-PBM period to 27% (60/221) in the post-PBM period (p < 0.001). The application of a PBM program was associated with a reduction in perioperative RBC transfusion by multivariate analysis (odds ratio 0.55, 95% CI 0.36-0.85, p = 0.007), and was associated with a reduction in the median number of RBC units transfused within transfused patients (p = 0.025). These effects persisted at day 30 after surgery (p = 0.029). CONCLUSION A perioperative PBM program in adult patients undergoing cardiac surgery was associated with a significant reduction in perioperative RBC transfusion, which persisted at day 30.

Intravenous iron administration before cardiac surgery reduces red blood cell transfusion in patients without anaemia. Br J Anaesth 2023; 131:981-988. [PMID: 37838604 DOI: 10.1016/j.bja.2023.09.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 09/02/2023] [Accepted: 09/14/2023] [Indexed: 10/16/2023] Open
Abstract
BACKGROUND Reducing the need for blood transfusion among patients undergoing cardiac surgery FLA reduce postoperative complications and mortality. Our study aimed to assess the effects of administering preoperative i.v. ferric carboxymaltose on postoperative red cell transfusion requirements in patients without anaemia undergoing on-pump cardiac surgery. METHODS This double-blind, randomised, placebo-controlled trial was conducted between October 2016 and November 2019, with a follow-up period of up to 6 weeks after surgery. Patients without anaemia who underwent on-pump cardiac surgery were included as participants and administered i.v. iron in the form of ferric carboxymaltose or placebo once, 24-72 h before surgery. The primary outcome was the number of red cell units transfused during the first four postoperative days, and the secondary outcome measures were blood haemoglobin concentrations at 4 days and 6 weeks after surgery. RESULTS The 200 patients included were randomly assigned to the ferric carboxymaltose (n=102) and placebo (n=98) groups. By postoperative Day 4, a significantly lower mean number of red cell units were transfused in the ferric carboxymaltose than in the placebo group, 0.3 (0.8) vs 1.6 (4.4), respectively; P=0.007. The mean haemoglobin concentrations on postoperative Day 4 were 9.7 (1) g dl-1 and 9.3 (1) g dl-1, respectively (P=0.03). Corresponding values at 6 weeks after surgery were 12.6 (1.4) g dl-1 and 11.8 (1.5) g dl-1, respectively (P=0.012). CONCLUSIONS In patients without anaemia undergoing on-pump cardiac surgery, treatment with a single dose of 1000 mg ferric carboxymaltose i.v. 1-3 days before surgery significantly reduced the need for red cell transfusions and increased the postoperative haemoglobin concentration. CLINICAL TRIAL REGISTRATION NCT02939794.

Abstract
BACKGROUND We assessed whether implementation of an immediate preoperative treatment in anemic patients could result in fewer perioperative packed red blood cell (PRBC) transfusions and improved outcomes in a real-world setting. METHODS From January 1, 2020, to November 31, 2022, we implemented a perioperative protocol for anemic patients (hemoglobin (Hb) level in women <11.5 g/dL, men <12.5 g/dL), which included subcutaneous erythropoietin α, intravenous Iron, and intramuscular vitamin B12 (all given preoperatively) and per os iron and folic acid given once a day postoperatively. We retrospectively compared all patients receiving the protocol to all eligible patients who were operated upon in the 4 years prior to implementation of the protocol. Primary outcome was amount of PRBC transfusions during surgery and index admission. RESULTS In the months after protocol implementation, 114 patients who received the treatment protocol were compared with 236 anemic patients in the 4 years prior to who did not receive the protocol. The treatment reduced total PRBC use (control group median 4 [2-7] units vs. treatment 2 [1-3] units, p < 0.0001) and the incidence of postoperative blood products transfusions (treatment group 58 patients, 50.88% vs. control group 177 patients, 75%, p < 0.0001). Hb prior to discharge was higher among the protocol group (treatment median 9 g/dL [8.3-9.5 g/dL] vs. control 8.6 g/dL [8.1-9.1 g/dL], p = 0.0081). CONCLUSION Despite some differences compared with previously described protocols, the implementation of a perioperative treatment protocol for anemic patients was associated with a reduction in PRBC transfusion in a real-world setting.

Abstract
OBJECTIVE To assess the relationship between red blood cell (RBC) transfusion exposure and in-hospital mortality after isolated coronary artery bypass graft (CABG) surgery. BACKGROUND RBC transfusion was commonly used to treat anemia in isolated CABG surgery, but transfusion was found an independent risk factor of postoperative mortality; recent guidelines on patient blood management strategy issued in the last decade may have changed transfusion incidence and related mortality. METHODS A retrospective cohort study was conducted from the National database on patients' hospital discharge reports. Consecutive adult patients who underwent isolated CABG surgery in France from January 1, 2016, to December 31, 2018, were included. The primary outcome was the in-hospital mortality rate. RBC transfusion during the hospital stay was identified by specific codes and ordered as categorical variables (no, moderate, or massive transfusion). RESULTS A total of 37,498 participants were studied [mean (SD) age, 66.5 (9.6) years, 31,587 (84.2%) were men]. In-hospital mortality rate was 1.45% (n=541) and RBC transfusion rate was 9.4% (n=3521). In-hospital deaths were more frequent among transfused patients [1.06% (361) if no transfusion up to 10.2% (n=113) if massive transfusion]. After adjustment for confounding variables, RBC transfusion remained a significant independent factor of in-hospital mortality: odds ratio=1.66 (95% confidence interval: 1.27-2.19, P <0.001) for moderate transfusion, 6.40 (95% confidence interval: 5.07-8.09, P <0.001) if massive. CONCLUSIONS AND RELEVANCE Despite a modest patients' exposure to transfusion, this study suggests that RBC administration is an independent factor of in-hospital mortality in isolated CABG surgery.

Abstract
AIMS AND OBJECTIVES To construct a predictive nomogram of the risk of nosocomial infections among patients after cardiac valve replacement surgery. BACKGROUND Nosocomial infections are a standout challenge that worsens the prognosis of patients after valve replacement surgery. However, studies on the nomogram of nosocomial infections in these patients have remained scarce. DESIGN A retrospective cohort study. METHODS Patients (n = 720) following valve replacement surgery from 2018 to 2019 were selected. LASSO regression and multivariate logistic regression were utilised to ascertain predictors of nosocomial infections. The predictive performance of the nomogram was appraised by calibration and discrimination. Decision and impact curves were used to assess the clinical utility. Internal validation was implemented via 1000 bootstrap samples to mitigate overfitting. TRIPOD guidelines were used in this study. RESULTS One hundred and fifty one patients (20.97%) experienced nosocomial infections following valve replacement surgery. Heart failure, preoperative anaemia, valve material, American Society of Anesthesiologists score ≥ IV, prolonged duration of surgery, duration of mechanical ventilation ≥ 24 h and indwelling nasogastric tube were predictors of nosocomial infections. Using these variables, we developed a predictive nomogram of the occurrence of nosocomial infections and the internal validation results demonstrated good discrimination and calibration of the nomogram. The clinical decision and impact curve revealed significant clinical utility. CONCLUSIONS The present study constructed a nomogram for predicting the risk of nosocomial infections in patients following cardiac valve replacement surgery. This nomogram may strengthen the effective screening of patients at high risk of nosocomial infections. RELEVANCE TO CLINICAL PRACTICE This risk warning tool can assist clinical staff in making decisions and providing individualised infection control measures for patients, which has a significant reference value for clinical practice. NO PATIENT OR PUBLIC CONTRIBUTION The data for this study were obtained from the hospital database, and the entire process of the study did not involve patient participation.

Abstract
BACKGROUND Perioperative anemia is common in cardiac surgery. Few studies investigated the effect of postoperative intravenous (IV) iron supplementation and were mostly inconclusive. METHODS Design: A randomized single-center, double-blind, placebo-controlled, parallel-group trial. PARTICIPANTS 195 non-anemic patients were recruited from December 2018 to December 2020: 97 patients received 1 g of ferric carboxymaltose (FCM) and 98 patients received 100 mL of physiological serum on postoperative day 1. MEASUREMENTS hemoglobin levels, reticulocyte count, serum iron, serum ferritin, and transferrin saturation were measured at induction of anesthesia, postoperative days 1, 5, and 30. Transfusion rate, duration of mechanical ventilation, critical care unit length of stay, and side effects associated with IV iron administration were measured. The primary outcome was hemoglobin level on day 30. Secondary outcomes included iron balance, transfused red cell packs, and critical care unit length of stay. RESULTS At day 30, the hemoglobine level was higher in the FCM group than in the placebo group (mean 12.9 ± 1.2 vs. 12.1 ± 1.3 g/dL (95%CI 0.41-1.23, p-value <0.001)). Patients in the FCM group received fewer blood units (median 1[0-2] unit vs. 2 [0-3] units, p-value = 0.037) and had significant improvement in iron balance compared to the control group. No side effects associated with FCM administration were reported. CONCLUSION In this randomized controlled trial, administration of FCM on postoperative day 1 in non-anemic patients undergoing cardiac surgery increased hemoglobin levels by 0.8 g/dL on postoperative day 30, leading to reduced transfusion rate, and improved iron levels on postoperative day 5 and 30.

Abstract
Iron is an essential element and involved in a variety of metabolic processes including oxygen transport, cellular energy production, energy metabolism of heart muscles, brain function, cell growth and cell differentiation. Preoperative anaemia is an independent risk factor for poor outcome. Recently, iron deficiency was considered only in the context of anaemia. However, negative consequences of iron deficiency in the absence of anaemia have been described for patients undergoing cardiac surgery. To date, the benefit of intravenous iron supplementation in these patients has been controversially debated. In this review, we discuss the latest progress in studies of intravenous iron supplementation in iron deficient cardiac surgical patients.

Abstract
INTRODUCTION Preoperative anemia is an important and relatively common problem in patients undergoing cardiac surgery, and its treatment is crucial in improving postoperative outcomes. The use of recombinant erythropoietin is one of the suggested methods in this field. Therefore, in the present study, we sought to evaluate the effects of recombinant erythropoietin on hemoglobin (Hb) levels and blood transfusion needs in cardiac surgery in patients with preoperative anemia. METHODS This randomized nonblind clinical trial was performed on patients with mild-to-moderate anemia (Hb <12 g/dL in men and Hb <11 g/dL in women) undergoing cardiac surgery at a referral heart hospital (Tehran, Iran). The patients were randomly divided into two groups of 33 patients. In the intervention group, recombinant erythropoietin was administered at a dose of 500 IU/kg one to three days before surgery. Intra- and postoperative Hb levels and the need for blood transfusion were recorded during surgery and for 3 days afterward. RESULTS The use of packed red blood cells in the operating room was similar in the intervention and control groups (P = 0.156), but it was significantly lower in the intensive care unit in the intervention group (P = 0.030). The mean Hb, which was initially identical in the two groups (P > 0.05), showed a significantly lower decrease in the intervention group (P = 0.001). No significant differences were observed concerning other variables. CONCLUSIONS The use of recombinant erythropoietin (500 IU/kg/day) one to three days before cardiac surgery in our anemic patients blunted a reduction in Hb levels and decreased blood transfusion needs.

Abstract
The concept of "prehabilitation" consists of screening for and identification of pre-existing disorders followed by medical optimization. This is performed for many types of surgery, but may have profound impacts on outcomes particularly in cardiac surgery given the multiple comorbidities typically carried by these patients. Components of prehabilitation include direct medical intervention by preoperative specialists as well as significant care coordination and shared decision making. In this two-part review, the authors describe existing evidence to support the optimization of various preoperative problems and present a few institutional protocols utilized by our center for cardiac presurgical care. This first installment will focus on the management of anemia, obesity, sleep apnea, diabetes, and cardiac rehabilitation prior to surgery. The second will focus on frailty, malnutrition, respiratory disease, alcohol and smoking cessation, and depression.

Abstract
Background Iron deficiency has deleterious effects in patients with cardiopulmonary disease, independent of anemia. Low ferritin has been associated with increased mortality in patients undergoing cardiac surgery, but modern indices of iron deficiency need to be explored in this population. Methods We conducted a retrospective single-centre observational study of 250 adults in a UK academic tertiary hospital undergoing median sternotomy for non-emergent isolated aortic valve replacement. We characterised preoperative iron status using measurement of both plasma ferritin and soluble transferrin receptor (sTfR), and examined associations with clinical outcomes. Results Measurement of plasma sTfR gave a prevalence of iron deficiency of 22%. Patients with non-anemic iron deficiency had clinically significant prolongation of total hospital stay (mean increase 2.2 days; 95% CI: 0.5–3.9; P = 0.011) and stay within the cardiac intensive care unit (mean increase 1.3 days; 95% CI: 0.1–2.5; P = 0.039). There were no deaths. Defining iron deficiency as a plasma ferritin < 100 µg/L identified 60% of patients as iron deficient and did not predict length of stay. No significant associations with transfusion requirements were evident using either definition of iron deficiency. Conclusions These findings indicate that when defined using sTfR rather than ferritin, non-anemic iron deficiency predicts prolonged hospitalisation following surgical aortic valve replacement. Further studies are required to clarify the role of contemporary laboratory indices in the identification of preoperative iron deficiency in patients undergoing cardiac surgery. An interventional study of intravenous iron targeted at preoperative non-anemic iron deficiency is warranted.

A protocol for prospective observational study to determine if non-anaemic iron deficiency worsens postoperative outcome in adult patients undergoing elective cardiac surgery: the IDOCS study. Perioper Med (Lond) 2022; 11:4. [PMID: 35130975 PMCID: PMC8822844 DOI: 10.1186/s13741-022-00239-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 01/06/2022] [Indexed: 11/26/2022] Open
Abstract
Background Pre-operative anaemia has been associated independently with worse outcomes after cardiac surgery in adults and is often caused by absolute or functional iron deficiency. Iron deficiency is a continuum ending with anaemia, and therefore it is plausible that pre-operative early or ‘non-anaemic’ iron deficiency may also be associated with worse outcomes in patients undergoing cardiac surgery. Methods We have designed a prospective, observational study to determine if there is an association between non-anaemic iron deficiency and worse outcomes after cardiac surgery in adults. Patients without anaemia undergoing elective cardiac surgery will be allocated to an iron-deficient and an iron-replete group based on standard pre-operative blood tests (ferritin, transferrin saturation and C-reactive protein). The primary outcome is days alive and at home on postoperative day 30. The key secondary outcomes are days alive and at home on postoperative day 90 and readmission to acute care. Other secondary outcomes include health-related quality of life questionnaires, quality of postoperative recovery, postoperative complications, changes in haemoglobin concentration, and requirement for allogeneic blood products. The planned study sample size is 240 patients per group, which has 83% power to detect a median difference of 1.25 days in the primary outcome. The study commenced in March 2018, and recently completed recruitment, with data audit and cleaning ongoing. Discussion This study will be conducted using a rigorous, prospective observational design; it will provide peak bodies and clinicians with high-quality evidence concerning the associations between non-anaemic iron deficiency and patient-centred outcomes after elective cardiac surgery. Our primary and key secondary outcomes are known to have great importance to clinicians and patients alike and align with the recommendations of the StEP-COMPAC group for outcomes in prospective peri-operative research. The definition used for iron deficiency accounts for both absolute and functional iron deficiency and make use of standard pre-operative blood tests to make this determination, easing the transition of results into clinical practice. The study will be conducted in two relatively high-volume centres in a single high-income country. This limits the generalisability of study results to similar centres.

Abstract
Cardiac surgery is typically attributed with a significant risk of intraoperative blood loss and allogeneic blood transfusions. Intraoperative blood loss, allogenic blood transfusions, high dose anticoagulation requirement, and interactions with cardiopulmonary bypass (CPB) have all been linked to cardiac surgeries. To reduce unnecessary transfusions and their negative effects, it is recommended to follow evidence-based multidisciplinary strategies, which are collectively termed patient blood management (PBM). This review highlights the most recent blood conservation strategies in adult cardiac surgery, which can be employed pre-operatively, intra-operatively, and postoperatively, to enhance red cell mass and attenuate the utilization of packed red blood cells (PRBCs) and other blood products.

Abstract
Blood disorders that can contribute to abnormal bleeding can have a detrimental effect during cardiac surgery. Patients who are known to have such pathologies should be investigated thoroughly and cautious measures would need to be taken when cardiac surgery is needed in this cohort. The majority of current literature for cardiac surgery in patients with von Willebrand Disease and haemophilia are case reports. Nevertheless, evidence shows that optimising factor levels pre, intra and postoperatively offers outcomes similar to that of patients without these disorders. Preoperative screening followed by appropriate iron therapy reduces mortality for patients with anaemia. In this group, haemoglobin levels can be improved postoperatively through iron supplementation. The management strategy of cardiac surgery for people with blood disorders requires a multidisciplinary approach that is highly individualised for each patient. It is essential to adequately adjust preoperative, perioperative and postoperative care to the patient's blood disorder in order to achieve outcomes similar to that of patients without blood disorders.

Abstract
BACKGROUND/PURPOSE Anemia affects the postoperative course of patients undergoing a major surgical procedure. However, it remains unclear whether anemia has a different impact on the long-term outcome of patients with malignant or benign pancreatic disease. METHODS A retrospective analysis of patients undergoing pancreatic surgery for pancreatic malignancies or chronic pancreatitis was conducted between January 2012 and June 2018 at the University Hospital Dresden, Germany. The occurrence of preoperative anemia and the administration of pre-, intra-, and postoperative blood transfusions were correlated with postoperative complications and survival data by uni- and multivariate analysis. RESULTS A total of 682 patients were included with 482 (70.7%) undergoing surgical procedures for pancreatic malignancies. Univariate regression analysis confirmed preoperative anemia as a risk factor for postoperative complications > grade 2 according to the Clavien-Dindo classification. Multivariate regression analyses indicated postoperative blood transfusion as an independent risk factor for postoperative complications in patients with a benign (OR 20.5; p value < 0.001) and a malignant pancreatic lesion (OR 4.7; p value < 0.01). Univariate and multivariate analysis revealed preoperative anemia and pre-, intra-, and postoperative blood transfusions as independent prognostic factors for shorter overall survival in benign and malignant patients (p value < 0.001-0.01). CONCLUSION Preoperative anemia is a prevalent, independent, and adjustable factor in pancreatic surgery, which poses a significant risk for postoperative complications irrespective of the entity of the underlying disease. It should therefore be understood as an adjustable factor rather than an indicator of underlying disease severity.

Abstract
Iron deficiency anaemia is highly prevalent worldwide. In the surgical patient, anaemia of any cause implies higher morbidity and mortality in the post-operative period. This is especially important in patients with peripheral artery disease, as they have very high rates of anaemia due to iron deficiency or other causes. In intermittent claudication, anaemia is a predictor of death in the medium term. Patients with critical ischaemia have higher prevalence of anaemia and it is an indicator of amputation and death in the medium term. Specific protocols need to be developed for these patients since the natural history of their disease does not allow for the correction of anaemia before surgery.

Abstract
Untreated preoperative anemia increases the risk of morbidity and mortality and there is increasing evidence that early intervention for preoperative anemia improves outcomes after major surgery. Accordingly, anemia management clinics have been established in various institutions in the USA. As an example, the University of Iowa Hospitals and Clinics outpatient clinic treats pre-surgical anemic patients, who undergo major surgery with anticipated blood loss of more than 500 mL, by providing effective standardized care in a timely manner. This standardized care is an integral part of patient blood management to reduce perioperative blood transfusion and improve patient outcomes. The importance of preoperative anemia management has not yet been sufficiently recognized in Japan. Timely intervention for preoperative anemia should be incorporated into routine pre-surgical patient care in Japan.

Abstract
INTRODUCTION Acute limb ischaemia (ALI) forms a significant part of the vascular surgery workload and carries with it high rates of morbidity and mortality. Anaemia is also common amongst vascular surgical patients and has been linked with poor outcomes in some subgroups. We aimed to assess the frequency of anaemia in patients with ALI and its impact on survival and complications following revascularisation to help direct future efforts to optimise outcomes in this patient group. METHODS A retrospective analysis of prospectively collected departmental data on patients undergoing surgical intervention for ALI between 2014 and 2018 was performed. Anaemia was defined as a pre-operative haemoglobin (Hb) of <120 g/L for women and <130 g/L for men. The primary outcome was overall survival, assessed with the Kaplan-Meier estimator, with application of Cox proportional hazard modelling to adjust for confounding covariates. RESULTS There were 158 patients who underwent treatment for ALI: 89 (56.3%) of these were non-anaemic with a mean Hb of 146 (SD = 18.4), and 69 (43.7%) were anaemic with a mean Hb of 106 (SD = 13.4). Anaemic patients had a significantly higher risk of death than their non-anaemic counterparts on univariate analysis (HR = 2.11, 95% CIs, 1.28-3.5, p = 0.0036). There was ongoing divergence in survival up to around 6 months between anaemic and non-anaemic groups. Under the Cox model, anaemia was similarly significant as a predictor of death (HR = 2.15, 95% CIs, 1.17-3.95, p = 0.013), accounting for recorded comorbidities, medication use and blood transfusion. CONCLUSIONS Anaemia is a significant and independent risk factor for death following revascularisation for ALI and can be potentially be modified. Vascular surgical centres should ensure they have robust pathways in place to identify and consider treating anaemia. There is scope for further work to assess how to best optimise a patient's levels of circulating haemoglobin.

Abstract
Background Preoperative anemia and transfusion are associated with worse outcomes. This study aims to identify the prevalence of preoperative anemia, transfusion rates on surgery day, and predictors of transfusion in elective cardiac surgery patients at our centre. We also aim to evaluate our preoperative intervention program, and examine the intervention window for anemia before surgery. Methods This study included 797 adult patients who underwent elective cardiac surgery at a tertiary hospital. Multivariable logistic regression analysis was used to identify predictors of transfusion on surgery day. Results Preoperative anemia was present in 15% of patients. Anemic patients had a significantly higher transfusion rate at 53% compared to 10% in non-anemic patients. Hemoglobin concentration, estimated glomerular filtration rate (eGFR), body surface area (BSA), and total cardiopulmonary bypass time were predictive of transfusion on surgery day. Patients had a median of 7 days between initial visit and surgery day, however, referral to the blood conservation clinic was only done for 8% of anemic patients and treatment was initiated in 3% of anemic patients. Among the 3 anemic patients who received treatment, 2 did not require blood transfusion on surgery day. Conclusions Preoperative anemia is present in 15% of patients at our centre and these patients have 53% transfusion rates on surgery day. Hemoglobin concentration, eGFR, BSA, and total cardiopulmonary bypass time were predictors of transfusion on surgery day. Patients had a median of 7 days between initial visit and surgery day. Referral and anemia treatment were infrequently initiated in preoperative anemic patient.

Abstract
BACKGROUND Recent guidelines on transfusion in cardiac surgery suggest that hemoglobin might not be the only criterion to trigger transfusion. Central venous oxygen saturation (Svo2), which is related to the balance between tissue oxygen delivery and consumption, may help the decision process of transfusion. We designed a randomized study to test whether central Svo2-guided transfusion could reduce transfusion incidence after cardiac surgery. METHODS This single center, single-blinded, randomized controlled trial was conducted on adult patients after cardiac surgery in the intensive care unit (ICU) of a tertiary university hospital. Patients were screened preoperatively and were assigned randomly to two study groups (control or Svo2) if they developed anemia (hemoglobin less than 9 g/dl), without active bleeding, during their ICU stay. Patients were transfused at each anemia episode during their ICU stay except the Svo2 patients who were transfused only if the pretransfusion central Svo2 was less than or equal to 65%. The primary outcome was the proportion of patients transfused in the ICU. The main secondary endpoints were (1) number of erythrocyte units transfused in the ICU and at study discharge, and (2) the proportion of patients transfused at study discharge. RESULTS Among 484 screened patients, 100 were randomized, with 50 in each group. All control patients were transfused in the ICU with a total of 94 transfused erythrocyte units. In the Svo2 group, 34 (68%) patients were transfused (odds ratio, 0.031 [95% CI, 0 to 0.153]; P < 0.001 vs. controls), with a total of 65 erythrocyte units. At study discharge, eight patients of the Svo2 group remained nontransfused and the cumulative count of erythrocyte units was 96 in the Svo2 group and 126 in the control group. CONCLUSIONS A restrictive transfusion strategy adjusted with central Svo2 may allow a significant reduction in the incidence of transfusion. EDITOR’S PERSPECTIVE

Abstract
OBJECTIVES The benefits of preoperative intravenous (IV) iron treatment in cardiac surgery patients with preoperative anaemia or iron deficiency have not been well-established. We performed a systematic review and meta-analysis to determine the effects of treating preoperative anaemia or iron deficiency with IV iron in adult cardiac surgery patients. METHODS We searched Cochrane Central Register of Controlled Trials, Medical Literature Analysis and Retrieval Systems Online and Excerpta Medica Database for randomized controlled trials (RCTs) and observational studies comparing IV iron to oral iron or no iron. We performed title and abstract, full-text screening, data extraction and risk of bias assessment independently and in duplicate. We pooled data using a random effects model and evaluated the overall quality of evidence. RESULTS We identified 4 RCTs and 7 observational studies. Pooled data from observational studies suggested a benefit of IV iron compared to no iron on mortality [relative risk 0.39, 95% confidence interval (CI) 0.23-0.65; P < 0.001, very low quality], units transfused per patient (mean difference -1.22, 95% CI -1.85 to -0.60; P < 0.001, very low quality), renal injury (relative risk 0.50, 95% CI 0.36-0.69; P < 0.001, very low quality) and hospital length of stay (mean difference -4.24 days, 95% CI -6.86 to -1.63; P = 0.001, very low quality). Pooled data from RCTs demonstrated a reduction in the number of patients transfused with IV iron compared to oral or no iron (relative risk 0.81, 95% CI 0.70-0.94; P = 0.005, moderate quality). The pooled estimates of effect from RCTs for mortality, hospital length of stay, units transfused per patient and renal injury were consistent in direction with observational studies. CONCLUSIONS This meta-analysis suggests that IV iron improves postoperative morbidity in adult cardiac surgery patients with preoperative anaemia or iron deficiency. A large, rigorous, placebo-controlled, double-blinded, multicentre trial is needed to clarify the role of IV iron in this patient population.

Preoperative Anemia Treatment with Intravenous Iron Therapy in Patients Undergoing Abdominal Surgery: A Systematic Review. Adv Ther 2021; 38:1447-1469. [PMID: 33580485 PMCID: PMC7932933 DOI: 10.1007/s12325-021-01628-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 01/15/2021] [Indexed: 12/21/2022]
Abstract
Introduction Preoperative anemia is associated with increased morbidity, mortality, and healthcare costs. As a result of the increased incidence of chronic blood loss and iron deficiency anemia in abdominal surgery patients and its impact on patient outcomes, we systematically evaluated the quality of evidence for preoperative intravenous (IV) administration of iron to patients with anemia undergoing major abdominal surgery with the focus on clinical outcomes. Methods In this systematic review, PubMed, Cochrane, The Cumulative Index to Nursing and Allied Health Literature, Web Of Science, and Excerpta Medica Database databases were searched up to 2019 using specific keywords. Inclusion criteria were patients that were over 18 years of age, underwent abdominal surgery, and received an IV iron treatment in the preoperative setting. Results The nine studies included in the final systematic review do not provide consistent evidence of a reduced incidence of allogeneic blood transfusions with preoperative IV iron administration. However, IV iron administration did consistently cause a significant increase in hemoglobin levels relative to oral iron therapy or no iron. Conclusion Overall, these findings are consistent in that IV iron administration is highly effective at rapidly increasing hemoglobin levels in patients with iron deficiency anemia undergoing major abdominal surgery. Unfortunately, there is currently no evidence of reduced incidence of allogeneic blood transfusions or other enhanced outcomes.

Abstract
Enhanced Recovery Programs (ERPs) are protocols involving the whole patient surgical journey. These protocols are based on multimodal, multidisciplinary, evidence-based, and patient-centered approaches aimed at improving patient recovery after a surgical intervention. Such programs have shown striking positive results in different surgical specialties. However, only a few research groups have incorporated preoperative, intraoperative, and postoperative evidence-based interventions in bundles used to standardize care and build cardiac surgery ERPs. The Enhanced Recovery After Surgery Society recently published evidence-based recommendations for perioperative care in cardiac surgery. Their recommendations included 22 perioperative interventions that may be part of any cardiac ERP. However, various components integrated in already-published cardiac ERPs were neither graded nor reported in these recommendations. The goals of the current review are to present published cardiac ERPs and their effects on patient outcomes and reported components incorporated into these ERPs and to discuss the objectives and scope of cardiac ERPs.

Preemptive intravenous iron therapy versus autologous whole blood therapy for early postoperative hemoglobin level in patients undergoing bimaxillary orthognathic surgery: a prospective randomized noninferiority trial. BMC Oral Health 2021; 21:16. [PMID: 33413311 PMCID: PMC7791750 DOI: 10.1186/s12903-020-01359-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 12/09/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Previous studies have reported the efficacy and safety of intravenous (IV) iron therapy during the perioperative period as an alternative and adjunct to allogeneic blood transfusion. Preemptive IV iron therapy provides noninferior hemoglobin levels on postoperative day (POD) 1 compared to autologous whole blood therapy (AWBT) in healthy patients who had undergone bimaxillary orthognathic surgery. METHODS This was a prospective, patient-randomized, noninferiority trial. After excluding 2 patients, 64 patients were divided into two groups: the IV iron therapy group (patients received IV iron infusion 4 weeks before surgery; n = 32) and the AWBT group (2 units of autologous whole blood were collected 4 and 2 weeks before surgery; n = 32). The primary outcome was hemoglobin level on POD 1 and the prespecified noninferiority limit was - 1 g/dL. RESULTS Baseline data were comparable, including hemoglobin and iron levels, between the two groups. Immediately before surgery, the levels of hemoglobin, iron, and ferritin were higher in the IV iron group than in the AWBT group. The mean treatment difference (iron group-whole blood group) in hemoglobin level on POD 1 between the two groups was 0.09 (95% CI = - 0.83 to 1.0). As the lower limit of the 95% CI (- 0.83) was higher than the prespecified noninferiority margin (δ = - 1), noninferiority was established. On POD 2, the hemoglobin level became lower in the iron group, which eventually led to greater requirement of allogeneic blood transfusion compared to the whole blood group. However, the iron group did not require allogeneic blood transfusion during or early after surgery, and the whole blood group showed continuously higher incidence of overt iron deficiency compared to the iron group. CONCLUSION As collection of autologous whole blood caused overt iron loss and anemia before surgery and intraoperative transfusion of whole blood was not able to prevent the occurrence of persistent iron deficiency after surgery, IV iron therapy was found to have potential benefits for iron homeostasis and subsequent erythropoiesis in healthy patients early after bimaxillary orthognathic surgery.

Determining Optimal Treatment to Correct Preoperative Anemia and Reduce Perioperative Allogeneic Blood Transfusions in Cardiac Surgery: A Retrospective Cohort Study. J Cardiothorac Vasc Anesth 2021; 35:2631-2639. [PMID: 33483268 DOI: 10.1053/j.jvca.2020.12.044] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 12/24/2020] [Accepted: 12/28/2020] [Indexed: 01/09/2023]
Abstract
OBJECTIVE Preoperative anemia management reduces red blood cell (RBC) transfusion and adverse outcomes, but how best to optimize the patient's hemoglobin (Hgb) before cardiac surgery remains unclear. The authors sought to determine the optimal treatment of anemia using iron and epoetin alfa before cardiac surgery. DESIGN Retrospective cohort study. SETTING Sunnybrook Health Sciences Centre, University of Toronto. PARTICIPANTS The study comprised 532 consecutive patients referred to the outpatient Blood Conservation Clinic and who underwent cardiac surgery between 2008 and 2018. INTERVENTIONS Of the 532 patients, 207 received oral iron, 84 received intravenous (IV) iron, 71 received epoetin alfa, 92 received combination therapy, and 78 received no treatment. MEASUREMENTS AND MAIN RESULTS Multivariate linear, logistic, and Poisson regressions modelled preoperative Hgb, the change from referral to preoperative Hgb (∆Hgb), the odds of transfusion, and the number of RBC units transfused, while accounting for baseline covariates. Higher ∆Hgb was associated with IV iron >600 mg (9.80 g/L [6.17-13.42]), epoetin alfa >80,000 U (5.80 g/L [2.20-9.40]), and higher referral Hgb (1.91 g/L [1.09-2.74] per 10 g/L). Higher preoperative Hgb (odds ratio 0.76 [0.64-0.90]; count ratio 0.84 [0.77-0.93] per 10 g/L) corresponded to a lower likelihood of being transfused and transfusion of fewer RBC units. CONCLUSIONS Preoperative IV iron >600 mg and epoetin alfa >80,000 U each was associated with significant increases in Hgb. Higher preoperative Hgb was associated with a lower likelihood of transfusion and transfusion of fewer RBC units. The authors recommend that cumulative preoperative doses of IV iron >600 mg and epoetin alfa >80,000 U be used for treatment of anemia before cardiac surgery.

Abstract
Coronary artery bypass grafting (CABG) remains a routine operation despite major advancements in angioplastic procedures. Around 200,000 CABG procedures are performed annually in the U.S. Patients who are not candidates for angioplasty intervention often have advanced coronary disease and comorbidities that raise the risk of heart failure with decreased ejection fraction to around 25%. Over the years, significant developments in various preoperative interventions have occurred; in this paper, we suggest a multidisciplinary preoperative algorithm that can be included in a regularly scheduled multidisciplinary care plan.

Abstract
OBJECTIVES The aim of this study was to evaluate the effect of preoperative anemia on early postoperative outcomes in a population of patients undergoing lung transplantation. DESIGN Single-center retrospective study of lung transplantation recipients between April 2013 and June 2018. The primary outcome was hospital length of stay. SETTING Ronald Reagan UCLA Medical Center, Los Angeles, CA, a tertiary academic medical center. PARTICIPANTS Patients presenting from home for lung transplantation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A total of 435 patients underwent lung transplantation during the study period. After exclusion, 342 were included in the analysis. The prevalence of preoperative anemia was 54% (n = 183); however, only 11% of anemic patients received treatment for anemia before transplantation. Multivariate regression analysis indicated that lower hemoglobin levels were associated with longer hospital lengths of stay (p = 0.049). Preoperative anemia also was independently associated with an increased risk for redo surgery for bleeding (odds ratio 4.89; p = 0.007). No association between preoperative anemia and any of the other postoperative outcomes examined was found. CONCLUSIONS Preoperative anemia in patients undergoing lung transplantation is undertreated and independently associated with an increased risk for redo surgery for bleeding. Additional studies regarding reasons for this association and effect of treatment are necessary to improve outcomes.

Abstract
Background Anemia is common in cardiac surgery affecting 25-40% of patients and associated with increased blood transfusions, morbidity, mortality, and higher hospital costs. Higher rates of stroke, acute renal injury, and total number of adverse postoperative outcomes have also been reported to be associated with preoperative anemia. This systematic review assessed the current evidence for preoperative intravenous iron on major outcomes following cardiac surgery. Methods Outcome measures included postoperative hemoglobin, transfusion rates, major adverse events, and mortality. The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and articles were identified using PubMed, Cochrane, CLINAHL, WOS, and EMBASE databases. Articles were included if they compared patients with and without preoperative anemia based on treatment with intravenous iron. Quality was assessed using Cochrane Risk of Bias Tool and Newcastle-Ottawa scale, and strength of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Results Of the articles reviewed, six met inclusion criteria. These included four randomized double-blind prospective cohort studies, one randomized non-blinded prospective study, and one non-randomized non-blinded prospective study with historical control. Across studies, 1,038 patients were enrolled. Two studies showed higher hemoglobin with iron therapy, and only one study showed significant differences in multiple outcomes such as transfusion and morbidity. Conclusions Given the paucity of studies and biases within them, the current evidence for treatment with intravenous iron prior to cardiac surgery is weak. More evidence is needed to support the administration of preoperative intravenous iron in cardiac surgery patients.

Abstract
Despite progress in the medical and device therapy for heart failure (HF), the prognosis for those with advanced HF remains poor. Acute heart failure (AcHF) is the rapid development of, or worsening of symptoms and signs of HF typically leading to hospitalization. Whilst many HF decompensations are managed at a ward-based level, a proportion of patients require higher acuity care in the intensive care unit (ICU). Admission to ICU is associated with a higher risk of in-hospital mortality, and in those who fail to respond to standard supportive and medical therapy, a proportion maybe suitable for mechanical circulatory support (MCS). The optimal pre-operative management of advanced HF patients awaiting durable MCS or cardiac transplantation (CTx) is vital in improving both short and longer-term outcomes. This review will summarize the clinical assessment, hemodynamic profiling and management of the patient with AcHF in the ICU. The general principles of pre-surgical optimization encompassing individual systems (the kidneys, the liver, blood and glycemic control) will be discussed. Other factors impacting upon post-operative outcomes including nutrition and sarcopenia and pre-surgical skin decolonization have been included. Issues specific to durable MCS including the assessment of the right ventricle and strategies for optimization will also be discussed.

Abstract
BACKGROUND Anemia is associated with a higher mortality following standard endovascular aortic repair (EVAR). This study evaluates the impact of anemia on fenestrated endovascular aneurysm repair (FEVAR) for complex aneurysm (AAA) repair. METHODS All elective FEVARs performed between 2010 and 2018 at a tertiary vascular center were analyzed. Anemia was defined as a preoperative hemoglobin (Hb) of <120 g/L for women and <130 g/L for men (World Health Organization definition). Primary outcome was overall survival by Kaplan-Meier. Secondary outcomes included length of hospital stay (LOS) and myocardial infarction (MI). Cox proportional hazard analyses were conducted. RESULTS In total, 132 FEVAR patients were followed up for 3.7 (2.2) years. Thirty-eight patients were anemic [average Hb of 112 (13) g/L]. Groups were comparable for age, AAA diameter, body mass index, and comorbidity. Anemic patients had a lower baseline estimated glomerular filtration rate [64.1 (23.2) vs. 70.9 (18.8) mL/min/1.73 m2, P = 0.022] and a longer procedural time [242 (103) vs. 195.4 (88) min, P = 0.009] with no difference in the number of fenestrations (P = 0.696). Kaplan-Meier analysis demonstrated a higher mortality (log-rank P = 0.03) with 40% deceased versus 21% nonanemic (P = 0.04) at the end of follow-up. Anemic patients had more postoperative myocardial infarctions (MIs) (4 vs. 2, P = 0.037) and a longer LOS [9.2 (7.1) vs. 6.3 (6.8) days, P = 0.001]. Increasing Hb increased the likelihood of survival [hazard ratio, HR -0.8 (0.65-0.94), P = 0.038]. Postoperative transfusion was adversely associated with survival [HR 3.65 (1.05-12.8), P = 0.043]. CONCLUSIONS Anemia appears to be associated with an increased rate of postoperative MI, LOS, frequency of blood transfusion, and mortality rate following FEVAR but this surpassed by postoperative blood transfusion. Optimization of preoperative Hb should be considered as a potential target for improvements in clinical outcomes and hypothetically a consequential reduction in postoperative red blood cell transfusion need.

Abstract
Preoperative treatment of anemia with intravenous iron is inconsistent despite known risks of anemia and allogeneic blood transfusions. Limited research exists on the effectiveness of preoperative intravenous iron for chronic kidney disease (CKD) patients. We discuss a patient with severe anemia from advanced CKD, endometrial cancer, and menometrorrhagia. Her hemoglobin increased more than 2 g/dL after erythropoietin and two 750-mg ferric carboxymaltose infusions 5 weeks before a total abdominal hysterectomy and avoided blood transfusions perioperatively. By raising hemoglobin, preoperative intravenous iron and erythropoietin reduce blood transfusions and consequent risk of future allograft rejection and alloimmunization in potential transplant recipients.

Abstract
Anemia, transfusion and bleeding independently increase the risk of complications and mortality in cardiac surgery. The main goals of patient blood management are to treat anemia, prevent bleeding, and optimize the use of blood products during the perioperative period. The benefit of this program has been confirmed in many studies and its utilization is strongly recommended by professional organizations. This consensus report has been prepared by the authors who are the task members appointed by the Turkish Society of Cardiovascular Surgery, Turkish Society of Cardiology (TSC), and Society of Cardio-Vascular-Thoracic Anaesthesia and Intensive Care to raise the awareness of patient blood management. This report aims to summarize recommendations for all perioperative blood- conserving strategies in cardiac surgery.

Abstract
Background: Efforts have been made to minimize transfusion of packed red blood cells in
patients undergoing cardiac surgery with cardiopulmonary bypass. One method
concerns retrograde autologous priming. Although the technique has been used
for decades, results remain contradictory in terms of transfusion
requirements. Objective: This systematic literature review aimed to summarize the evidence for the
efficacy of retrograde autologous priming in terms of decreasing
perioperative packed red blood cell requirements in adults. Methods: Two researchers independently searched PubMed for articles published in the
past 10 years. The modified Cochrane collaboration Risk of Bias Tool and the
Research Triangle Institute Item Bank were used to assess bias. Results: Eight studies were included, of which two randomized and six observational
studies. Five studies, including one randomized study, report a significant
decrease in packed red blood cell use in the retrograde autologous priming
group compared to no retrograde autologous priming used. All studies are
flawed by at least a high risk bias of bias score on one item of the bias
assessment. Conclusion: Although most studies reported significantly fewer packed red blood cell
transfusions in the retrograde autologous priming group, it is important to
note that relatively few articles are available which are flawed by several
types of bias. Prospective, randomized multi-center trials are warranted to
conclude decisively on the benefits of retrograde autologous priming.

Abstract
Bleeding and transfusion are common in cardiac surgery and associated with poorer outcome. Bleeding is frequently due to coagulopathy caused by the complex interaction between cardiopulmonary bypass, major surgical trauma, anticoagulation management, and perioperative factors. Patient blood management has emerged to improve outcome by the prediction, prevention, monitoring, and treatment of bleeding and transfusion. Each part of this chain has several individual modalities and when combined leads to result in a better outcome. This article reviews the hemostasis disturbances in cardiac surgery with cardiopulmonary bypass and gives an overview of the most important patient blood management strategies.

Abstract
INTRODUCTION One-third of non-pregnant women worldwide are anemic.1 Anemia is a known independent risk factor for postoperative morbidity.2 Given that the vast majority of hysterectomies are not performed in the emergency setting, we designed this study to evaluate the effect of preoperative anemia on postoperative morbidity following laparoscopic hysterectomy performed for benign indications. Our main goal is to encourage surgeons to use anemia-corrective measures before surgery when feasible. MATERIAL AND METHODS Retrospective cohort study of 98 813 patients who underwent a laparoscopic hysterectomy between 2005 and 2016 for benign indications identified through the American College of Surgeons National Surgical Quality Improvement Program. Anemia was examined as a function of hematocrit and was analyzed as an ordinal variable stratified by anemia severity as mild, moderate or severe. Associations between preoperative anemia and patient demographics, preoperative comorbidities and postoperative outcomes were evaluated using univariate analyses. Multivariable logistic regression models were used to identify independent associations between hematocrit level and postoperative outcomes after adjusting for confounding covariates. At the multivariable logistic regression level, anemia severity was analyzed using hematocrit as a continuous variable to assess the independent association between each 5% decrease in hematocrit level and several postoperative morbidities. RESULTS Of the 98 813 patients who met our inclusion and exclusion criteria, 19.5% were anemic. A lower preoperative hematocrit was associated with higher body mass index, younger age, Black or African American race, longer operative times, and multiple other medical comorbidities. After appropriate regression modeling, anemia was identified as an independent risk factor for extended length of stay, readmission and composite morbidity after surgery. CONCLUSIONS Preoperative anemia is common among patients undergoing laparoscopic hysterectomy. Preoperative anemia increases patients' risk for multiple postoperative comorbidities. Given that most hysterectomies are performed in the elective setting, gynecologic surgeons should consider the use of anemia-corrective measures to minimize postoperative morbidity.

Abstract
Background Patients with end-stage liver disease frequently experience acute kidney injury (AKI) after living donor liver transplantation (LDLT). Serum levels of brain natriuretic peptide (BNP) have increasingly been accepted as a predictor of AKI in clinical settings. This study investigated the predictive role of intraoperative BNP levels in the early development of AKI after LDLT. Patients and methods Adult patients (≥19 years old) who had undergone elective LDLT from January 2011 to December 2017 were classified into the non-AKI and AKI groups according to the Kidney Disease: Improving Global Outcomes criteria. Serum levels of BNP were measured three times in the preanhepatic, anhepatic, and neohepatic phases. Perioperative data in recipients and donors were analyzed retrospectively. Results Sixty-one patients (22.4%) suffered from AKI immediately after LDLT. Severity according to AKI stage was as follows: 28 patients in stage 1 (10.3%), 18 patients in stage 2 (6.6%), and 15 patients in stage 3 (5.5%). In the neohepatic phase, both BNP levels and proportions of patients with high BNP levels (≥100 pg/mL) were higher in the AKI group than in the non-AKI group. Only BNP levels in the non-AKI and AKI stage 1 groups significantly decreased from the preanhepatic phase to the neohepatic phase; those in AKI stages 2 and 3 groups did not. In particular, BNP levels of all AKI stage 3 patients increased to more than 100 pg/mL, and the proportion of patients with high levels also increased significantly through the surgical phases in the AKI stage 3 group. In multivariate analyses, BNP levels in the neohepatic phase were significantly associated with early development of AKI after LDLT, as well as the total amount of packed red blood cells in transfusions and total duration of graft ischemia. Conclusions Monitoring serum levels of BNP is useful for predicting the early development of AKI after LDLT.

Abstract
BACKGROUND Adult cardiac surgery with extracorporeal circulation is known to be associated with increased risk of blood transfusion leading to adverse outcomes. Procedures like retrograde autologous priming (RAP) may reduce these negative side effects. This randomized prospective study was initiated to assess whether RAP using specifically designed RAP bag (Terumo) has immediate effects on patient outcome. METHODS One hundred eighteen adults undergoing elective CABG or elective aortic valve replacement were randomly assigned by a computer program into two groups: the RAP group (n = 54) in which the retrograde autologous priming was applied and the non-RAP (n = 64) group in which the same setting was used without the possibility to save priming volume. Patient demographics, preoperative characteristics and postoperative outcomes were analyzed for both groups. RESULTS The primary endpoint defined as rate of intraoperative blood transfusion was significantly reduced in the RAP-group (p = 0.04). The absolute risk reduction for RAP managed patients was 13.5 percent points. There were no significant differences in operation time and blood loss. No deaths and no myocardial infarctions were observed. The number of patients needed to treat to prevent at least one red blood cell transfusion was around 8 (NNT = 7.42). CONCLUSIONS Retrograde autologous priming is a safe and less invasive procedure which achieves clear benefits for adult cardiac surgery patients. In the light of increasing red blood cell transfusion risks and costs and the wish of patients to avoid a transfusion implementation of retrograde autologous priming is an interesting option.
