Perioperative anemia is an independent risk factor for postoperative morbidity and mortality. However, conceptual, logistical and administrative barriers persist that hinder the widespread implementation of protocols for their management. The project coordinator convened a multidisciplinary group of 9 experienced professionals to develop perioperative anemia management algorithms, based on a series of key points (KPs) related to its prevalence, consequences, diagnosis and treatment. These KPs were assessed using a 5-point Likert scale, from "strongly disagree [1]" to "strongly agree [5]"...

PURPOSE: Anemia has been shown to be a modifiable pre-operative, patient factor associated with outcome following arthroplasty. The aims of this retrospective study were to (1) ascertain the prevalence of preoperative anemia in patients undergoing primary and revision hip and knee arthroplasty at a tertiary referral center and (2) to test the association with outcome and whether it differs between primary and revision cases. METHODS: All hip and knee primary and revision arthroplasties performed at a Canadian academic, tertiary-care, arthroplasty center between 2012 and 2017 were included in this study...

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...

OBJECTIVES: To compare outcomes in patients on direct oral anticoagulants (DOACs) treated within 48 hours of last preoperative dose with those with surgical delays >48 hours. DESIGN: Retrospective cohort study. SETTING: Three academic Level 1 trauma centers. PATIENT SELECTION CRITERIA: Patients 65 years of age or older on DOACs before hip fracture treated between 2010 and 2018. Patients were excluded if last DOAC dose was >24 hours before admission, patient suffered from polytrauma, and/or delay to surgery was not attributed to DOAC...

BACKGROUND: Previous studies concerning the association between preoperative Hemoglobin (HB) level and the Length Of hospital Stay (LOS) in patients with non-cardiac surgery and non-obstetric surgery remain inconclusive. Herein, the objective of this study was to analyze whether and to what extent the preoperative HB level was connected with the LOS in non-cardiac and non-obstetric surgery patients. METHODS: This retrospective cohort study was performed at a single institution, involving patients who underwent elective non-cardiac, non-obstetric surgery from April 2007 to September 2013...

BACKGROUND: Anemia is a common complication of total hip arthroplasty (THA). In this study, we evaluated the preoperative risk factors for postoperative anemia after THA and developed a nomogram model based on related preoperative and intraoperative factors. METHODS: From January 2020 to May 2023, 927 THA patients at the same medical center were randomly assigned to either the training or validation cohort. The correlation between preoperative and intraoperative risk factors and postoperative anemia after THA was evaluated using univariate and multivariate logistic regression analysis...

<b><br>Introduction:</b> The rate of revisional surgeries following sleeve gastrectomy (SG) has increased. One-anastomosis gastric bypass (OAGB) appears to have multiple advantages as a primary bariatric procedure. OAGB as revisional surgery is still being investigated.</br> <b><br>Aim:</b> Evaluation of the efficacy and safety of OAGB performed as a post-SG revisional surgery.</br> <b><br>Materials and methods:</b> A single-center, retrospective cohort study was conducted using a routinely collected database of adults undergoing revisional OAGB after SG...

Prehabilitation is a comprehensive preparation of a patient for primarily surgical treatments. Its aim is to improve the patient'sgeneral condition so as to reduce the risk of complications and ensure the fastest possible recovery to full health. Thebasic components of prehabilitation include: improvement of nutritional status, appropriate exercises to improve functioning,psychological support, and help in eliminating addictions. Other important aspects of prehabilitation are: increasinghemoglobin levels in patients with anemia, achieving good glycemic control in patients with diabetes, treatment or stabilizationof any concurrent disorders, or specialist treatment associated with a specific procedure (endoprostheses, ostomyprocedure)...

Perioperative myocardial injury is a relatively common complication after noncardiac surgery associated with significant morbidity and mortality. It is frequently driven by physiologic factors such as hypotension, tachycardia, and anemia. Diagnosis of perioperative myocardial injury after noncardiac surgery is based on elevated cardiac troponin levels, greater than the 99th percentile of the assay's upper reference limit within 30 days of surgery. Perioperative myocardial injury is further classified into non-ischemic and ischemic based on the underlying pathophysiology...

BACKGROUND: Preoperative anemia is associated with adverse outcomes in cardiac surgery, yet it remains unclear what proportion of this association is mediated through red blood cell (RBC) transfusions. METHODS: This is a historical observational cohort study of adults undergoing coronary artery bypass grafting or valve surgery on cardiopulmonary bypass at an academic medical center between May 1, 2008, and May 1, 2018. A mediation analysis framework was used to evaluate the associations between preoperative anemia and postoperative outcomes, including a primary outcome of acute kidney injury (AKI)...

BACKGROUND/AIMS: Primary simultaneous bilateral total joint arthroplasty (simBTJA) can cause postoperative anemia. Clinicians might hesitate to discharge patients who have large changes in hemoglobin [Hgb], despite Hgb levels remaining above transfusion thresholds. This study was conducted to evaluate if delta Hgb or perioperative blood loss correspond with readmission in primary simBTJA patients not transfused perioperatively. METHODS: From 2015 - 2020, a retrospective chart review of primary simultaneous bilateral total hip/knee arthroplasty cases was conducted...

BACKGROUND: Red blood cell (RBC) transfusion in patients undergoing major elective cranial surgery is associated with increased postoperative morbidity and mortality. This study aims to identify the clinical outcome of transfused glioblastoma patients undergoing primary surgical tumor resection and identify risk factors for RBC transfusion. MATERIAL AND METHODS: Between 2009 and 2019, 406 patients underwent elective primary glioblastoma resection. For multivariate analysis to assess risk factors for RBC transfusion, logistic regression was conducted...

INTRODUCTION: Patients undergoing revision total hip surgery (RTHS) have a high prevalence of mild and moderate preoperative anemia, associated with adverse outcomes. The aim of this study was to investigate the association of perioperative allogeneic blood transfusions (ABT) and postoperative complications in preoperatively mild compared to moderate anemic patients undergoing RTHS who did not receive a diagnostic anemia workup and treatment before surgery. METHODS: We included 1,765 patients between 2007 and 2019 at a university hospital...

Renal transplantation is a complex surgical procedure requiring meticulous anesthetic planning to ensure patient safety and optimal graft function. In this comprehensive review, we examined various aspects of anesthesia management during renal transplantation, including preoperative, intraoperative, and postoperative care. Preoperative optimization involves the identification and management of risks to mitigate perioperative complications. Treatment with erythropoiesis-stimulating agents is recommended to correct anemia in transplant recipients with hemoglobin levels below 9-10 g/dl...

STUDY OBJECTIVE: To evaluate the association between pretransfusion and posttransfusion hemoglobin concentrations and the outcomes of children undergoing noncardiac surgery. DESIGN: Retrospective review of patient records. We focused on initial postoperative hemoglobin concentrations, which may provide a more useful representation of transfusion adequacy than pretransfusion hemoglobin triggers (the latter often cannot be obtained during acute surgical hemorrhage)...
