[PMID: 38960092 DOI: 10.1016/j.avsg.2024.04.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 03/11/2024] [Accepted: 04/08/2024] [Indexed: 07/05/2024]
Abstract
INTRODUCTION Deep vein thrombosis (DVT) is a medical condition characterized by forming a blood clot, or thrombus, in one of the deep veins, typically in the legs. It is a type of venous thromboembolism, which refers to the formation of blood clots in the veins. It is caused by Virchow's triad (stasis, hypercoagulation, and endothelial injury). OBJECTIVE Our main objective is to explore the effectiveness and safety of rivaroxaban and edoxaban in treating lower extremity DVT. METHODS We conducted a retrospective study involving 406 patients subjected to DVT treatment using direct oral anticoagulants (edoxaban and rivaroxaban) at our hospital. We recruited adult patients (aged 18 years and more) diagnosed with lower extremity DVT and received treatment with either rivaroxaban or edoxaban as the primary anticoagulant therapy for DVT. We excluded patients who received treatment with other anticoagulant medications (warfarin and heparin) as the primary therapy for DVT. RESULTS The groups showed statistically significant differences in red blood cell count and hemoglobin levels, with the edoxaban group having high values. However, the 2 groups observed no statistically significant differences in creatinine clearance, white blood cell count, platelet count, C-reactive protein, and D-dimer levels. The difference in the incidence of pulmonary embolism between the 2 groups was statistically significant (P value < 0.001). The edoxaban group had fewer pulmonary embolism patients than the rivaroxaban group. The reduction in recurrent thrombosis was significantly higher in the rivaroxaban group compared to the edoxaban group. There were no significant differences in the major bleeding at various sites across the 2 treatment groups (P > 0.05). CONCLUSIONS Rivaroxaban's pharmacokinetic profile includes rapid absorption and a relatively short half-life. It means that once administered, rivaroxaban quickly reaches its peak concentration in the blood and is subsequently eliminated from the body within a relatively short period. Edoxaban's pharmacokinetic profile may include slower absorption and a longer half-life than rivaroxaban. It can result in a slower rate of achieving peak concentration and a more prolonged presence in the bloodstream. These results emphasize the need for careful consideration of anticoagulant therapy in patients with underlying cancer and underscore the importance of managing risks while providing adequate anticoagulation to prevent thrombotic events.

Associations of preoperative anaemia with healthcare resource use and outcomes after colorectal surgery: a population-based cohort study. Br J Anaesth 2024; 133:58-66. [PMID: 38644160 PMCID: PMC11213985 DOI: 10.1016/j.bja.2024.03.018] [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: 12/20/2023] [Revised: 03/20/2024] [Accepted: 03/21/2024] [Indexed: 04/23/2024] Open
Abstract
BACKGROUND Preoperative anaemia is common in patient undergoing colorectal surgery. Understanding the population-level costs of preoperative anaemia will inform development and evaluation of anaemia management at health system levels. METHODS This was a population-based cohort study using linked, routinely collected data, including residents from Ontario, Canada, aged ≥18 yr who underwent an elective colorectal resection between 2012 and 2022. Primary exposure was preoperative anaemia (haemoglobin <130 g L-1 in males; <120 g L-1 in females). Primary outcome was 30-day costs in 2022 Canadian dollars (CAD), from the perspective of a publicly funded healthcare system. Secondary outcomes included red blood cell transfusion, major adverse events (MAEs), length of stay (LOS), days alive at home (DAH), and readmissions. RESULTS We included 54,286 patients, with mean 65.3 (range 18-102) years of age and 49.0% females, among which 21 264 (39.2%) had preoperative anaemia. There was an absolute adjusted cost increase of $2671 per person at 30 days after surgery attributable to preoperative anaemia (ratio of means [RoM] 1.05, 95% confidence interval [CI] 1.04-1.06). Compared with the control group, 30-day risks of transfusion (odds ratio [OR] 4.34, 95% CI 4.04-4.66), MAEs (OR 1.14, 95% CI 1.03-1.27), LOS (RoM 1.08, 95% CI 1.07-1.10), and readmissions (OR 1.16, 95% CI 1.08-1.24) were higher in the anaemia group, with reduced DAH (RoM 0.95, 95% CI 0.95-0.96). CONCLUSIONS Approximately $2671 CAD per person in 30-day health system costs are attributable to preoperative anaemia after colorectal surgery in Ontario, Canada.

The association of hemoglobin with postoperative delirium and atrial fibrillation after cardiac surgery: a retrospective sub-study. BRAZILIAN JOURNAL OF ANESTHESIOLOGY (ELSEVIER) 2024; 74:744424. [PMID: 36894011 PMCID: PMC11148484 DOI: 10.1016/j.bjane.2023.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 02/21/2023] [Accepted: 02/26/2023] [Indexed: 03/09/2023]
Abstract
BACKGROUND Most cardiac surgery patients experience postoperative anemia. Delirium and Atrial Fibrillation (AF) are common and independent predictors of morbidity and mortality. Few reports examine their association with postoperative anemia. This study aims to quantify the association between anemia and these outcomes in patients undergoing cardiac surgery. METHODS This post-hoc analysis of the DECADE randomized controlled trial ran at six academic US hospitals. Patients aged 18-85 years with heart rate > 50 bpm undergoing cardiac surgery who had daily hemoglobin measurements in the first 5 Postoperative Days (POD) were included. Delirium was assessed twice daily with the Confusion Assessment Method for the ICU (CAM - ICU), preceded by the Richmond Agitation and Sedation Scale, with patients excluded from assessment if sedated. Patients had daily hemoglobin measurements, continuous cardiac monitoring plus twice-daily 12-lead electrocardiograms, up to POD4. AF was diagnosed by clinicians blinded to hemoglobin levels. RESULTS Five hundred and eighty-five patients were included. Mean postoperative hemoglobin Hazard Ratio (HR): 0.99 (95% CI 0.83, 1.19; p = 0.94) per 1 g.dL-1 hemoglobin decrease. 197 (34%) developed AF, mainly on POD = 2.3. Estimated HR = 1.04 (95% CI 0.93, 1.17; p = 0.51) per 1 g.dL-1 hemoglobin decrease. CONCLUSIONS Most patients undergoing major cardiac surgery were anemic in the postoperative phase. AF and delirium occurred in 34% and 12% of patients, respectively, but neither were significantly correlated with postoperative hemoglobin.

Abstract
PURPOSE Anemia reduces the blood's ability to carry and deliver oxygen. Following cardiac surgery, anemia is very common and affects up to 90% of patients. Nevertheless, there is a paucity of data examining the prognostic value of postoperative anemia. In this narrative review, we present findings from the relevant literature on postoperative anemia in cardiac surgery patients, focusing on the incidence, risk factors, and prognostic value of postoperative anemia. We also explore the potential utility of postoperative anemia as a therapeutic target to improve clinical outcomes. SOURCE We conducted a targeted search of MEDLINE, Embase, and the Cochrane Database of Systematic Reviews up to September 2022, using a combination of search terms including postoperative (post-operative), perioperative (peri-operative), anemia (anaemia), and cardiac surgery. PRINCIPAL FINDINGS The reported incidence of postoperative anemia varied from 29% to 94% across the studies, likely because of variations in patient inclusion criteria and classification of postoperative anemia. Nonetheless, the weight of the evidence suggests that postoperative anemia is common and is an independent risk factor for adverse postoperative outcomes such as acute kidney injury, stroke, mortality, and functional outcomes. CONCLUSIONS In cardiac surgery patients, postoperative anemia is a common and prognostically important risk factor for postoperative morbidity and mortality. Nevertheless, there is a lack of data on whether active management of postoperative anemia is feasible or effective in improving patient outcomes.

Abstract
BACKGROUND Life-threatening blunt thoracic aortic injury (BTAI) typically occurs alongside multiple other traumatic injuries. Symptoms of BTAI can range from being asymptomatic in the case of intimal tears to becoming catastrophic in the case of uncontained aortic ruptures. The aim of this research was to examine the clinical outcomes for those who underwent thoracic endovascular aortic repair (TEVAR) in hospital settings. Methods: A cross-sectional retrospective study was conducted using patient data that were extracted from Al-Noor Specialist Hospital, Makkah, Saudi Arabia, for the duration between January 2011 and December 2021. This study included data from all patients aged 18 and up who had been diagnosed with BTAI and had undergone TEVAR. The BTAI diagnoses were confirmed using CT scans. Logistic regression was utilized to identify predictors of patients' health status improvement and length of stay. RESULTS A total of 80 patients were involved. Around 50.0% (n=40) of the patients had grade 3 thoracic aortic injuries. The median duration of stay was 14.00 days (Interquartile range 21.00). Only one patient developed post-procedure complications (1.3%). Almost one-third (31.3%; n=25) of the patients required subclavian coverage. One patient developed intraoperative endoleak (1.3%). One patient developed an access site complication (1.3%). The mortality rate within 30 days of the operation was 1.3%. The vast majority of the patients (92.5%; n=74) showed improvement upon discharge from the hospital. The baseline patient characteristics and length of hospitalization had no effect on the improvement of patient status upon discharge or their length of stay (p>0.05). CONCLUSION Patients with BTAI have shown an excellent success rate with TEVAR and a low complication rate. Predictors of procedure success and length of stay need to be identified; however, this can't be done without larger-scale investigations. This can aid in the development of preventative measures that improve clinical outcomes for the patients.

Abstract
BACKGROUND Patient blood management (PBM) is an evidence-based approach recommended to improve patient outcomes. Change in practices is often challenging. We report here data from French surgical departments before and after a standardized implementation of a PBM program. METHODS This was a national, multicenter, observational study in surgical centers ("expert" centers with an already established protocol for preoperative anemia or "pilot" centers). Data from consecutive surgical patients of different specialties were retrieved before and after the implementation of a PBM program. Primary outcome variables (preoperative anemia treatment rates, transfusion rates, and length of hospital stay) before and after the implementation of a PBM program were analyzed with segmented regression adjusted on confounders (American Society of Anesthesiologists [ASA] scores and centers). RESULTS A total of 1618 patients (ASA physical status III and IV, 38% in the first period and 45% in the second period) were included in expert (N = 454) or pilot (N = 1164) centers during the first period (January 2017-August 2022) and 1542 (N = 440 and N = 1102, respectively) during the second period (January 2020-February 2023). After implementation of the PBM program, the rate of preoperative anemia treatment increased (odds ratio, 2.37; 95% confidence interval [CI], 1.20-4.74; P = .0136) and length of hospital stay in days decreased (estimate, -0.11; 95% CI, -0.21 to -0.02; P = .0186). Transfusion rate significantly decreased only in expert centers (odds ratio, 0.17; 95% CI, 0.03-0.88; P = .0354). CONCLUSIONS PBM practices in various surgical specialties improved significantly after the implementation of a PBM program. However, too many patients with preoperative anemia remained untreated.

Abstract
BACKGROUND Anemia, characterized by low hemoglobin levels, is a global public health concern. Anemia is an independent factor worsening outcomes in various patient groups. Blood transfusion has been the traditional treatment for anemia; its triggers, primarily based on hemoglobin levels; however, hemoglobin level is not always an ideal trigger for blood transfusion. Additionally, blood transfusion worsens clinical outcomes in certain patient groups. This narrative review explores alternative triggers for red blood cell transfusion and their physiological basis. MAIN TEXT The review delves into the physiology of oxygen transport and highlights the limitations of using hemoglobin levels alone as transfusion trigger. The main aim of blood transfusion is to optimize oxygen delivery, necessitating an individualized approach based on clinical signs of anemia and the balance between oxygen delivery and consumption, reflected by the oxygen extraction rate. The narrative review covers different alternative triggers. It presents insights into their diagnostic value and clinical applications, emphasizing the need for personalized transfusion strategies. CONCLUSION Anemia and blood transfusion are significant factors affecting patient outcomes. While restrictive transfusion strategies are widely recommended, they may not account for the nuances of specific patient populations. The search for alternative transfusion triggers is essential to tailor transfusion therapy effectively, especially in patients with comorbidities or unique clinical profiles. Investigating alternative triggers not only enhances patient care by identifying more precise indicators but also minimizes transfusion-related risks, optimizes blood product utilization, and ensures availability when needed. Personalized transfusion strategies based on alternative triggers hold the potential to improve outcomes in various clinical scenarios, addressing anemia's complex challenges in healthcare. Further research and evidence are needed to refine these alternative triggers and guide their implementation in clinical practice.

Abstract
OBJECTIVE Preoperative anemia has been identified as a modifiable risk factor for multiple adverse outcomes. In real clinical practice, considering treatment of anemia would increase costs and delay surgery. Patients undergoing total hip arthroplasty (THA) with mild anemia are usually neglected and still underdiagnosed or inadequately treated. This study investigated the effects of preoperative borderline anemia and anemia intervention before THA on perioperative outcomes. METHODS We screened 706 patients from those receiving THA at our hospital from January 2020 to January 2022, with 112 in the borderline anemia group and 594 in the non-anemia group. The cohort for this retrospective study was created by using propensity score matching (PSM) and subgroup analysis. The primary outcome was perioperative blood loss, while secondary outcomes were the rate of allogeneic blood transfusion and human serum albumin transfusion, perioperative laboratory indicators, postoperative length of stay, and complications. The independent sample t-test and the Mann-Whitney U-test were used to analyze continuous data, and the Pearson χ2 -test or the Fisher exact test was used to analyze categorical variables. RESULTS After PSM, there was no significant difference in perioperative blood loss between patients in the borderline anemia group and the non-anemia group. The primary outcomes of hidden (p = 0.004) and total (p = 0.005) blood loss were significantly lower in the intervention group than in the control group. No statistical differences were found in allogeneic blood transfusion, human serum albumin transfusion, postoperative length of stay, or complications (p > 0.05). CONCLUSIONS Anemia treatments for patients with borderline anemia before THA significantly reduced hidden blood loss and total blood loss in the perioperative period and decreased the drop of hemoglobin and hematocrit without increasing postoperative complications.

Smoor RM, Rettig TCD, Vernooij LM, Groenewegen EM, van Dongen HPA, Noordzij PG. The effect of postoperative intravenous iron in anaemic, older cardiac surgery patients on disability-free survival (AGE ANEMIA study): study protocol for a multi-centre, double-blind, randomized, placebo-controlled trial. Trials 2023; 24:693. [PMID: 37885026 PMCID: PMC10601172 DOI: 10.1186/s13063-023-07725-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 10/12/2023] [Indexed: 10/28/2023] Open
Abstract
BACKGROUND Postoperative anaemia is common in older cardiac surgery patients and often caused by iron deficiency. Anaemia may negatively affect recovery after cardiac surgery. This study aims to determine the efficacy of treatment of postoperative iron deficiency anaemia (IDA) with intravenous iron (IVI) on disability 90 days after cardiac surgery in older patients. METHODS This is a randomized placebo-controlled double-blind multi-centre trial. In total, 310 patients aged ≥ 70 years with moderate IDA on postoperative day 1 (haemoglobin 85-110 g/L and ferritin concentration < 100 μg/L or iron saturation < 20%) after uncomplicated elective cardiac surgery (aortic valve repair or coronary artery bypass graft surgery) will be included. Patients will be randomly allocated to receive either IVI (ferric derisomaltose) or placebo (sodium chloride 0.9%) on postoperative day 1 in a 1:1 ratio, stratified by centre and type of cardiac surgery. The primary outcome is disability measured by the 12-item World Health Organization Disability Assessment score 2.0 after 90 days. Secondary outcome measures are the number of postoperative red blood cell (RBC) transfusions, change in reticulocyte haemoglobin content (pg) from randomization to hospital discharge, Hb levels at discharge, hospital complications, dyspnoea (assessed with the Rose Dyspnoea Scale) and health-related quality of life (HRQL) (assessed with The Older Persons and Informal Caregivers-Short Form (TOPICS-SF) questionnaire) after 90 days and days alive and out of hospital after 90 days. Lastly, the functional outcomes (e.g. steep ramp or 6-min walk test) and Hb level after 90 days will be assessed as an exploratory endpoint. DISCUSSION The results of this study will demonstrate whether early treatment of postoperative IDA with IVI improves disability at 90 days in older cardiac surgery patients. TRIAL REGISTRATION ClinicalTrials.gov NCT04913649. Registered on June 4, 2021.

Penny-wise and pound-foolish: the challenges of preoperative anaemia management. Br J Anaesth 2023:S0007-0912(23)00231-3. [PMID: 37244835 DOI: 10.1016/j.bja.2023.04.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 04/15/2023] [Accepted: 04/20/2023] [Indexed: 05/29/2023] Open
Abstract
The timely correction of anaemia before major surgery is important for optimising perioperative patient outcomes. However, multiple barriers have precluded the global expansion of preoperative anaemia treatment programmes, including misconceptions about the true cost/benefit ratio for patient care and health system economics. Institutional investment and buy-in from stakeholders could lead to significant cost savings through avoided complications of anaemia and red blood cell transfusions, and through containment of direct and variable costs of blood bank laboratories. In some health systems, billing for iron infusions could generate revenue and promote growth of treatment programmes. The aim of this work is to galvanise integrated health systems worldwide to diagnose and treat anaemia before major surgery.

Abstract
BACKGROUND Perioperative anemia has been associated with increased risk of red blood cell transfusion and increased morbidity and mortality after surgery. The optimal approach to the diagnosis and management of perioperative anemia is not fully established. OBJECTIVE To develop consensus recommendations for anemia management in surgical patients. METHODS An international expert panel reviewed the current evidence and developed recommendations using modified RAND Delphi methodology. RESULTS The panel recommends that all patients except those undergoing minor procedures be screened for anemia before surgery. Appropriate therapy for anemia should be guided by an accurate diagnosis of the etiology. The need to proceed with surgery in some patients with anemia is expected to persist. However, early identification and effective treatment of anemia has the potential to reduce the risks associated with surgery and improve clinical outcomes. As with preoperative anemia, postoperative anemia should be treated in the perioperative period. CONCLUSIONS Early identification and effective treatment of anemia has the potential to improve clinical outcomes in surgical patients.

Benediktsson SB, Karason S, Sigurdsson MI. Haemoglobin levels and outcomes of subgroups of patients with pre-operative anaemia based on red cell size: A retrospective cohort study. Acta Anaesthesiol Scand 2023; 67:422-431. [PMID: 36635957 DOI: 10.1111/aas.14198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 12/28/2022] [Accepted: 01/05/2023] [Indexed: 01/14/2023]
Abstract
BACKGROUND Pre-operative anaemia is common and associated with adverse outcomes. We hypothesised that pre-operative anaemia would be evident more than 1 month pre-operatively, and that peri-operative changes in haemoglobin and post-operative outcomes differed between red cell size-based subsets of anaemia. METHODS A retrospective single-centre cohort study, including all patients 18 years and older undergoing their first surgery at Landspitali between January 2006 and December 2018 with available measurement of haemoglobin (Hb) within 30 days preceding surgery. Clinical data were compared between patients with subgroups of anaemia classified by mean corpuscular volume (MCV) into microcytic (MCV < 80 fl), normocytic (MCV 80-100 fl), and macrocytic (MCV > 100 fl) anaemia. The development of haemoglobin measurements from a nationwide database was plotted from 1 year pre-operatively to 2 years post-operatively. RESULTS Of 40,979 patients, 10,505 (25.6%) had pre-operative anaemia, of which 1089 (10.4%) had microcytic anaemia, 9243 (88.0%) had normocytic anaemia, and 173 (1.6%) had macrocytic anaemia. Patients within all subgroups of pre-operative anaemia had a higher degree of comorbidity and frailty burden and a low haemoglobin evident for more than 100 days pre-operatively and similar changes post-operatively. Post-operative prolonged recovery of haemoglobin was slower for macrocytic anaemia than other types of anaemia. All groups of patients with anaemia had a higher incidence of 30-day mortality, acute kidney injury, and rate of readmission compared with patients without anaemia. CONCLUSIONS Pre-operative anaemia is evident long prior to the procedure and its association with worse outcomes is similar regardless of red cell size.

Abstract
Anemia was a risk factor for a worse prognosis of many diseases. This study aims to investigate the relationship between anemia and the severity and prognosis of acute pancreatitis (AP). Inpatients hospitalized at the First Affiliated Hospital of Guangdong Pharmaceutical University with a primary diagnosis of AP between 1st July 2016 to 31st December 2020 were enrolled. Subsequently, disease severity, the incidence of complications, and the prognosis of patients with AP were compared between the anemic group and the non-anemic group. A total of 282 patients with acute pancreatitis were enrolled; 68.43% of them were also diagnosed with anemia. Notably, these patients had more severe disease (higher RANSON, acute physiologic assessment and chronic health evaluation-II, bedside index for severity in acute pancreatitis, and multiple organ dysfunction syndrome scores); higher incidence of organ failure (acute kidney injury [AKI] and acute heart failure); worse prognosis (higher incidence of vasoactive and diuretic agent use, longer hospital stays, and higher hospital costs) compared to that of patients without anemia (all P < .05). After adjusting for potential confounders, acute physiologic assessment and chronic health evaluation-II, bedside index for severity in acute pancreatitis, multiple organ dysfunction syndrome scores, hospital stay, and hospital costs in anemic patients were higher than those in non-anemic patients; besides, the incidence of AKI and using a diuretic agent in anemic patients was 6.645 and 4.053 times that of non-anemic patients in AP, respectively (all P < .05). Acute pancreatitis patients with anemia have more disease severity, higher incidence of AKI, and worse prognosis compared to those without anemia.

Acute Postoperative Anemia After Unilateral Primary Total Joint Arthroplasty: Restrictive Transfusion Thresholds are Safe for Discharge Regardless of Delta Hemoglobin. J Arthroplasty 2022; 37:1737-1742.e2. [PMID: 35483607 DOI: 10.1016/j.arth.2022.04.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 03/12/2022] [Accepted: 04/16/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Primary unilateral total joint arthroplasty (TJA) is associated with acute postoperative anemia that may require blood transfusion. Clinicians may worry about discharging patients after surgery who experience substantial decreases in hemoglobin (Hgb), even if their Hgb is above restrictive transfusion thresholds. The purpose of this study was to determine whether differences between preoperative and postoperative Hgb values (Delta) correlate with 90-day readmission in patients who did not receive perioperative transfusions. METHODS A retrospective review of patients undergoing primary unilateral TJA between 2015 and 2020 was performed. The primary outcome was whether a specific cutoff delta Hgb was predictive of readmission within 90 days due to anemia-related causes. Secondary outcomes included the presence of acute postoperative anemia and transfusion during readmission. RESULTS Six thousand seven hundred and ninety one patients had a median delta Hgb of 2.80. In total, 268 patients (3.95%) were readmitted within 90 days postoperatively, with two patients requiring transfusion during readmission. A significantly higher rate of readmission was found in patients with cardiovascular disease (5.16% versus 3.68%; P = .020). When constructing receiver operating characteristic curves, a cutoff value of 3.20 resulted in an area under curve of 0.595 (0.486-0.704). In patients with cardiovascular disease, a cutoff value of 3.10 resulted in an area under curve of 0.626 (0.466-0.787). CONCLUSION The magnitude of Hgb change was not predictive of anemia-related readmission within 90 days in patients who did not receive a perioperative transfusion. Patients experiencing higher delta Hgb values but remaining above the transfusion threshold may have a greater physiologic reserve.

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
Preoperative optimization of the therapeutic regime of comorbidities can lead to an improvement of the postoperative outcome and has the potential to reduce the financial burden on the health care system in revision hip arthroplasty. Patient-related factors and an increasing incidence of comorbidities lead to a higher risk of implant failure and revision for all causes. Important and potentially modifiable risk factors like preoperative anemia, coagulopathy, infectious disease (dental status, urinary tract infections, colonization with staphylococcus), metabolic conditions (obesity, malnutrition, diabetes mellitus, osteoporosis), and smoking need to be addressed. To achieve an optimal preoperative condition a multidisciplinary approach should be applied.

Intraoperative blood loss and the need for preoperative blood preparations in transgender women undergoing facial feminization surgeries: implications for surgeons. Int J Oral Maxillofac Surg 2022; 52:72-78.

Abstract
The aim of this retrospective study was to assess blood loss during facial feminization surgeries and to evaluate blood transfusion requirements. Data from the medical records of all male-to-female transgender patients (transwomen) treated with gender affirming hormones and undergoing facial feminization surgeries were analysed. The total blood loss was calculated based on the haemoglobin balanced method. Twenty transwomen (average age of 25.9 years) were enrolled. Group 1 included 10 transwomen who underwent cranioplasty, genioplasty, and mandibular angles refining, group 2 included six transwomen who underwent cranioplasty and genioplasty, and group 3 included four transwomen who underwent mandibular angles refining and genioplasty. The median calculated blood loss for groups 1, 2, and 3 was 1159.7 ml, 828.5 ml, and 546.2 ml, respectively. The group differences in surgical time, intraoperative fluid amounts, and calculated blood loss volumes were significant. None of the patients required an intraoperative blood transfusion and the hormonal treatment had no effect on the amount of calculated blood loss. Hence, blood loss during facial feminization surgeries is well controlled and does not lead to life-threatening events, precluding the possibility of providing generalized recommendations for preoperative blood transfusion preparations.

Abstract
BACKGROUND Anemia is the most common hematological finding in surgical patients. One-third of surgical patients were anemic during preoperative assessment. The presence of preoperative anemia was found to be related with increased morbidity, mortality, length of hospital stay, intensive care unit admissions and postoperative infections. OBJECTIVE To determine the prevalence and factors associated with preoperative anemia among adult patients scheduled for major elective surgery at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, 2020. METHODS After obtaining an ethical approval, hospital-based cross-sectional quantitative study was conducted from June to August 2020 in University of Gondar Hospital. Full blood count within two weeks of preoperative period was considered valid if there were no any factors that affect the hematologic system Descriptive statistics, cross-tabulations and binary logistic regression analysis were performed to identify factors associated withpreoperative anemia. The strength of the association was presented using AOR with 95% confidence interval and p-value < 0.05 was considered as statistically significant. RESULT A total of 185 patients enrolled with 100% response rate. We observed preoperative anemia in 36.8% patients. The multi-variable binary logistic analysis showed that ASA II and III [AOR: 3.8, CI: 1.6-9.2], recent prior surgery [AOR: 3.3, CI: 1.3-8.5], history of malignancy [AOR: 9.4, CI: 2.0-43.4], orthopedic procedure [AOR: 11.2, CI: 4.0-31.6] and gynecologic procedure [AOR: 5.2, CI: 1.7-14.5] were significantly associated with preoperative anemia. CONCLUSION The prevalence of preoperative anemia was high and ASA ≥2, recent prior surgery, history of malignancy, orthopedic surgery and gynecologic procedure were significantly associated with preoperative anemia. We recommend to clinicians to aim prevention, early detection and treatment of preoperative anemia among adult patients scheduled for major elective surgery to reduce risk of anemia and related adverse outcomes.

Abstract
Background Blood transfusion plays a vital role in medical practice. Evaluation of blood utilization in a blood bank is a crucial step in good transfusion practice. It is the inception towards assessing the present and future demands for blood and also avoiding unnecessary transfusions. Methods Retrospective analysis of one-year data, available in the blood bank of Gulab Devi Hospital Lahore, was done to study blood transfusion practice. Issue registers were accessed to retrieve the required information such as gender, age, blood group, pre-transfusion Hemoglobin level, ward, clinical diagnosis, and indication for the transfusion. The data was analyzed using SPSS version 20 software. Frequency and percentages were used to summarize categorical demographics and clinical variables. Results A total of 1181 units were requested from the hospital during our study period. Majority of the requests were for the female patients (69%) of the reproductive age group (21 to 30 years). Blood group B positive was most frequent in our study population. Maximum requests were from reproductive health departments (39.9%). Surgery was the major diagnostic category to require blood transfusions (31.8%). Elective surgery constituted the major indication requiring blood transfusion at our hospital (41.3%). Conclusion Blood utilization patterns vary significantly within geographical regions, hospital to hospital, and according to clinical practices as well as patients’ clinical findings. Moreover, diseases burden, level of organization, and advancement of healthcare facilities in various settings contribute to the significant contrast in blood utilization trends.

Liu YM, Huang H, Gao J, Zhou J, Chu HC. Hemoglobin Concentration and Post-Operative Delirium in Elderly Patients Undergoing Femoral Neck Fracture Surgery. Front Med (Lausanne) 2022; 8:780196. [PMID: 35071265 PMCID: PMC8766508 DOI: 10.3389/fmed.2021.780196] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 12/03/2021] [Indexed: 02/05/2023] Open
Abstract
This study aimed to determine the relationship between hemoglobin (Hb) concentration and post-operative delirium (POD) in elderly patients undergoing femoral neck fracture (FNF) surgery and to investigate whether the change in Hb concentration is associated with POD and the risk factors for POD. A total of 889 patients admitted with FNF between January 2016 and December 2020 were enrolled in this single-center, retrospective, case–control study. Hb concentrations were determined at admission and post-operative day 1 and the change in Hb concentration was defined as the absolute value of difference in pre-operative and post-operative Hb concentration. POD was assessed using the Confusion Assessment Method for the Intensive Care Unit (ICU) or the Confusion Assessment Method once a daily after surgery. The logistic regression analysis was performed for statistical analysis. In total, 172 (19.3%) patients developed POD and 151 (87.8%) patients developed POD within post-operative 3 days. Low pre-operative Hb concentration [p = 0.026, odds ratio (OR) = 0.978] and significant change in Hb concentration (p = 0.006, OR = 1.033) were significantly associated with POD. After excluding change in Hb concentration or pre-operative Hb concentration, neither of them was significantly associated with POD (p > 0.05). The interaction analysis of change in Hb concentration and pre-operative Hb concentration in the logistic regression model was negative. There was no significant relationship between post-operative Hb concentration and POD. Age (p < 0.001, OR = 1.072), stroke history (p = 0.003, OR = 2.489), post-operative ICU transfer (p = 0.007, OR = 1.981), and visual analog scale score within post-operative 2 days (p1 = 0.016 and p2 = 0.006) were independently associated with POD in the logistic regression analysis. Patients with low pre-operative Hb concentrations and high changes in Hb concentration seem to have an increased risk of POD and should receive more attention. Old age, stroke history, post-operative ICU transfer, and pain within post-operative 2 days were significantly associated with POD.

Short-term high-dose intravenous iron reduced peri-operative transfusion after staggered bilateral total knee arthroplasty: A retrospective cohort study. Vox Sang 2021; 117:562-569. [PMID: 34897718 DOI: 10.1111/vox.13230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 11/23/2021] [Accepted: 11/28/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND AND OBJECTIVES Staggered bilateral total knee arthroplasty, two procedures performed 4-7 days apart during a single hospitalization, has an increased risk of blood transfusion. This observational study aimed to evaluate whether immediate post-operative single, high-dose intravenous iron supplementation could reduce transfusion requirements and facilitate anaemia recovery in patients. MATERIALS AND METHODS We retrospectively analysed 131 patients who underwent staggered bilateral total knee arthroplasty. The ferric carboxymaltose (FCM) group received 1000 mg of FCM after the first operation. The non-FCM group did not receive intravenous iron. The transfusion rate and post-operative complications were compared between the groups. The anaemia rate was evaluated pre-operatively, during hospitalization, and 5 weeks after the second total knee arthroplasty. RESULTS The FCM group comprised 78 patients (59.5%). The rate (21.8% vs. 47.2%, p = 0.004) and amount of transfusion (0 [0-2] vs. 0 [0-0], p = 0.001) was significantly lower in the FCM group than in the non-FCM group. Although both groups' pre-operative haemoglobin concentrations were not significantly different, the FCM group demonstrated higher haemoglobin values 5 weeks post surgery (12.25 ± 0.83 mg/dl vs. 11.48 ± 1.36 mg/dl, p < 0.001). More non-FCM patients developed moderate to severe anaemia at 5 weeks post surgery (p < 0.001). The mortality and complication rates were not significantly different. CONCLUSIONS Immediate post-operative, high-dose, intravenous iron treatment may contribute to reduced transfusion rates, facilitate haemoglobin recovery after staggered bilateral total knee arthroplasty, and minimize the development of moderate to severe anaemia.

Association of preoperative anemia and increased risk of blood transfusion and length of hospital stay in adults undergoing hip and knee arthroplasty: An observational study in a single tertiary center. Health Sci Rep 2021; 4:e448. [PMID: 34938895 PMCID: PMC8661511 DOI: 10.1002/hsr2.448] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 10/20/2021] [Accepted: 10/21/2021] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND AND AIMS Anemia is a common feature in patients presenting for major elective surgery, and it is considered an independent risk factor associated with adverse outcomes. Although several studies suggest that preoperative anemia is associated with poor outcomes after elective orthopedic surgery, data are still scarce in middle- and low-income countries where this problem may be even greater. The objective of this study was to evaluate the impact of preoperative anemia in clinical outcomes in patients submitted to hip and knee arthroplasty in a single tertiary hospital. METHODS Medical records of 234 adult patients submitted to knee and hip arthroplasty from January 2018 to July 2020 were retrospectively reviewed. Patient's demographics (ie, age and gender), pre- and postoperative hemoglobin level (Hb), allogeneic red blood cell (RBC) transfusion, intensive care admission, length of hospital stay, hospital readmissions, and mortality up to 30 days after the surgery were analyzed. Outcomes were evaluated according to preoperative anemia status based on World Health Organization (WHO) criteria. RESULTS Mean age was 70 years with a slight female predominance (57.6%). The prevalence of anemia was 30.7% (72/234) being more prevalent in female (33.3% vs 26.7%). Preoperative anemia was significantly associated with greater rate of blood transfusion (34.5% vs 5.6%; P = .001), prolonged length of hospital stay (6.48 days vs 3.36 days; P = .001), and higher rate of intensive care unit admission (47.2% and 29.6% P = .009). Preoperative anemia had no effect on 30-day readmission and mortality for both males and females. CONCLUSIONS Our retrospective study demonstrated that preoperative anemia is a common problem among orthopedic patients and is associated with increased transfusion risk and worse outcomes. Strategies to identify and treat anemic patients before elective surgery are critical to improving clinical outcomes.

Abstract
Understanding of how the human organism functions has preoccupied researchers in medicine for a very long time. While most of the mechanisms are well understood and detailed thoroughly, medicine has yet much to discover. Iron (Fe), Copper (Cu), and Zinc (Zn) are elements on which organisms, ranging from simple bacteria all the way to complex ones such as mammals, rely on these divalent ions. Compounded by the continuously evolving biotechnologies, these ions are still relevant today. This review article aims at recapping the mechanisms involved in Fe, Cu, and Zn homeostasis. By applying the knowledge and expanding on future research areas, this article aims to shine new light of existing illness. Thanks to the expanding field of nanotechnology, genetic disorders such as hemochromatosis and thalassemia can be managed today. Nanoparticles (NPs) improve delivery of ions and confer targeting capabilities, with the potential for use in treatment and diagnosis. Iron deficiency, cancer, and sepsis are persisting major issues. While targeted delivery using Fe NPs can be used as food fortifiers, chemotherapeutic agents against cancer cells and microbes have been developed using both Fe and Cu NPs. A fast and accurate means of diagnosis is a major impacting factor on outcome of patients, especially when critically ill. Good quality imaging and bed side diagnostic tools are possible using NPs, which may positively impact outcome.

Abstract
INTRODUCTION Postoperative anaemia can affect more than 90% of patients undergoing major surgeries. Patients develop an absolute iron deficiency in the face of significant blood loss or preoperative anaemia and major surgery. Studies have shown the negative impact of these factors on transfusion requirements, infections, increased hospitalisation and long-term morbidities. AIM OF THE STUDY The research was performed to determine the correlation between intravenous iron administration in the postoperative period and improved haemoglobin correction trend. MATERIAL AND METHODS A prospective study was conducted to screen and treat iron deficiency in patients undergoing major surgery associated with significant bleeding. For iron deficiency anaemia screening, in the postoperative period, the following bioumoral parameters were assessed: haemoglobin, serum iron, transferrin saturation (TSAT), and ferritin, direct serum total iron-binding capacity (dTIBC), mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). In addition, serum glucose, fibrinogen, urea, creatinine and lactate values were also collected. RESULTS Twenty-one patients undergoing major surgeries (52,38% were emergency and 47,61% elective interventions) were included in the study. Iron deficiency, as defined by ferritin 100-300 μg/L along with transferrin saturation (TSAT) < 20 %, mean corpuscular volume (MVC) < 92 fL, mean corpuscular haemoglobin (MCH) < 33 g/dL, serum iron < 10 μmol/L and direct serum total iron-binding capacity (dTIBC) > 36 μmol/L, was identified in all cases. To correct the deficit and optimise the haematological status, all patients received intravenous ferric carboxymaltose (500-1000 mg, single dose). Using Quadratic statistical analysis, the trend of haemoglobin correction was found to be a favourable one. CONCLUSION The administration of intravenous ferric carboxymaltose in the postoperative period showed the beneficial effect of this type of intervention on the haemoglobin correction trend in these groups of patients.

Abstract
OBJECTIVES We investigated whether routine perioperative intravenous iron replenishment reduces the requirement for packed erythrocytes (pRBC) transfusion. SUMMARY BACKGROUND DATA Patients undergoing complex cardiac surgery are at high risk of developing postoperative iron deficiency anemia, thus requiring transfusion, which is associated with adverse outcomes. METHODS Patients were randomized to receive either ferric derisomaltose 20 mg/kg (n = 103) or placebo (n = 101) twice during the perioperative period: 3 days before and after the surgery. The primary endpoint was the proportion of patients who received pRBC transfusion until postoperative day (POD) 10. Hemoglobin, reticulocyte count, serum iron profile, hepcidin, and erythropoietin were serially measured. RESULTS pRBC was transfused in 60.4% and 57.2% of patients in the control and iron group, respectively (P = 0.651). Hemoglobin concentration at 3 weeks postoperatively was higher in the iron group than in the control group (11.6 ± 1.5 g/dl vs. 10.9 ± 1.4 g/dl, P < 0.001). The iron group showed higher reticulocyte count (205 [150-267]×103/μl vs. 164 [122-207]×103/μl, P = 0.003) at POD 10. Transferrin saturation and serum ferritin were significantly increased in the iron group than in the control group (P < 0.001). Serum hepcidin was higher in the iron group than in the control group at POD 3 (106.3 [42.9-115.9] ng/ml vs. 39.3 [33.3-43.6] ng/ml, P < 0.001). Erythropoietin concentration increased postoperatively in both groups (P = 0.003), with no between-group difference. CONCLUSIONS Intravenous iron supplementation during index hospitalization for complex cardiac surgery did not minimize pRBC transfusion despite replenished iron store and augmented erythropoiesis, which may be attributed to enhanced hepcidin expression.

Abstract
Abstract
Purpose of Review
Anemia is a very common complication in the post-operative period. Post-operative anemia is associated with poor outcomes including but not limited to infections, increased length of stay, circulatory overload, and mortality. The strategy of patient blood management focuses on three pillars that include the detection and treatment of pre-operative anemia; reduction of peri-operative blood loss; and harnessing and optimizing the patient-specific physiological reserve of anemia.
Recent Findings
Multiple studies in surgical patients have been conducted to study various methods of management of post-operative anemia. Recent advances in surgical techniques have also been studied to minimize blood loss. There is a widespread consensus on the use of intravenous iron in hospitalized post-operative patients after major surgery.
Summary
We discuss the most common causes of post-operative anemia and management focusing on measures to reduce blood loss and measures to increase red blood cell (RBC) mass. In this brief review, we present updates from the most relevant articles in the past 5 years and include updates from the 2018 international consensus statement on the management of post-operative anemia after major surgical procedures.

Intravenous iron supplementation after liver surgery: Impact on anemia, iron, and hepcidin levels-a randomized controlled trial. Surgery 2021; 170:813-821.

Abstract
BACKGROUND Anemia is a recognized risk factor for perioperative related morbidity and mortality and is frequently reported in liver surgeries with an estimated incidence of 32%. We aim to assess the impact of intravenous iron administration in the immediate postoperative period on anemia and iron status as well as to determine the kinetics of hepcidin after liver surgery. METHODS The HepciFer trial, a randomized controlled trial, included 50 patients undergoing liver surgery. In accordance with the randomization process, patients received either ferric carboxymaltose (15 mg/kg, maximum 1 g) or placebo 4 hours after surgery. RESULTS The mean hemoglobin level, 7 days after surgery, did not differ significantly between the intervention and control group (11.1 ± 1.8 g/dL and 10.4 ± 1.6 g/dL, respectively) with a mean difference of +0.7 g/dL ([95% confidence interval, -0.3 to +1.7], P = .173). Within patients receiving intravenous iron supplementation, none presented biological signs of functional iron deficiency. Hepcidin levels remained significantly higher during the observation period in the intervention group. Inflammatory biomarkers, red blood cells transfusion rate and hospital duration of stay were similar between groups. CONCLUSION Intravenous ferric carboxymaltose administration did not result in a significant increase of hemoglobin levels 7 days after surgery. However, this study suggests that intravenous iron supplementation in the immediate postoperative settings prevents functional iron deficiency. Intravenous iron supplementation overcame the hepcidin-mediated blockade of iron absorption and should be considered as the preferred route of administration in the postoperative period.

Abstract
Anemia is a common finding in the perioperative setting with significant untoward consequences including worsening of outcomes and diminished quality of life as well as increased risk of allogeneic blood transfusions. Here, we present 3 cases that illustrate how anemia can be perioperatively managed in patients undergoing cardiac, orthopedic, and oncology surgeries. Timely detection of anemia prior to high-blood loss surgeries can allow clinicians to manage it and optimize hemoglobin level, making patients better prepared for the surgery. Treatment of anemia should be guided by the etiology and may include erythropoietic agents, folic acid, B12, and iron preparations. Other blood management strategies geared toward reducing surgical blood loss such as autologous transfusion techniques and agents to optimize hemostasis are used during surgery and in the immediate postoperative period. Patients should be closely monitored following surgery for signs of ongoing bleeding in need of control. Finally, screening for and management of anemia should continue in the postoperative and postdischarge period, as persistence and recurrence of anemia can further undermine patient's outcomes.

Abstract
Unexpected intraoperative bleeding is associated with a reduced availability of crosslinking capacity (provided through factor XIII (FXIII)) per unit of generated thrombin. Furthermore, FXIII deficiency and thrombocytopenia (but not fibrinogen deficiency) are the most prevalent modulators of clot firmness in the immediate postoperative setting. In this study, we therefore evaluated whether levels of FXIII, fibrinogen, or the platelet count influenced the probability of intraoperative red cell transfusions in patients in the operating theatre. This retrospective study was comprised of 1023 patients, which were in need of blood product support in the operating theatre and of which 443 received red cell transfusions. Due to standard operating procedures, FXIII activity, fibrinogen concentration, and platelet count were measured before transfusion took place, but without influencing the decision to transfuse. FXIII deficiency was frequent (50%), as was thrombocytopenia (49%), but not fibrinogen deficiency (9%). FXIII deficiency was associated with a significantly increased probability to receive red cell transfusions (OR 4.58, 95% CI 3.46–6.05) as was thrombocytopenia (OR 1.94, 95% CI 1.47–2.56), but not fibrinogen deficiency (OR 1.09, 95% CI 0.67–1.76). Similar results were seen for cut-off independent evaluations (receiver operating characteristics (ROC) curves, using continuously distributed variables), where the areas under the curves (AUC) of red cell transfusion for FXIII activity was 0.744 (95% CI 0.716–0.770)/0.632 (95% CI 0.601–0.661) for the platelet count, and 0.578 (95% CI 0.547–0.609) for fibrinogen concentration. All AUCs were significantly different from each other (p < 0.0001 and p = 0.0106, respectively), indicating that FXIII activity was a significantly better predictor of red blood cell (RBC) transfusion than platelet count and fibrinogen concentration. These results suggest that pre-transfusion FXIII activity and to a lesser extent the platelet count influence the probability of intraoperative red cell transfusions. Modifying FXIII activity and/or the platelet count might influence the need for downstream red cell transfusion, thus potentially reducing transfusion associated morbidity. This, however, needs confirmation in future studies.

Abstract
Anemia is the most common hematological disease, and is defined by the World Health Organization as a condition in which the number of red blood cells and consequently oxygen-carrying capacity is insufficient to meet the physiological needs of the body. Anemia can occur throughout the perioperative period and has important clinical consequences. Preoperative anemia is usually regarded as no more than a surrogate marker of a patient's physical status, and it is not always adequately addressed before surgery. Postoperative anemia is a common event and occurs in 80-90% of patients who have undergone major surgery. This manuscript discusses the detection and management of preoperative anemia, the three pillars of patient blood management, perioperative anemia management, and risk stratification for anemia in the surgical setting.
