Perioperative anaemia

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)...

This manuscript provides an overview of the principles and requirements for implementing the ERAS program in thoracic surgery.The ERAS program optimises perioperative management of elective lung resection procedures and is based on the ERAS Guidelines for Thoracic Surgery of the ERAS Society. The clinical measures are described as in the current literature, with a focus on postoperative outcome. There are currently 45 enhanced recovery items covering four perioperative phases: from the prehospital admission phase (patient education, screening and treatment of potential risk factors such as anaemia, malnutrition, cessation of nicotine or alcohol abuse, prehabilitation, carbohydrate loading) to the immediate preoperative phase (shortened fasting period, non-sedating premedication, prophylaxis of PONV and thromboembolic complications), the intraoperative measures (antibiotic prophylaxis, standardised anaesthesia, normothermia, targeted fluid therapy, minimally invasive surgery, avoidance of catheters and probes) through to the postoperative measures (early mobilisation, early nutrition, removal of a urinary catheter, hyperglycaemia control)...

INTRODUCTION: Few studies have focused on the risk factors for hidden blood loss (HBL) during cement augmentation surgery for pathologic vertebral compression fraction (PVCFs). METHOD: From January 2014 to December 2020, the clinical data of 169 PVCF patients (283 levels) who underwent cement augmentation were retrospectively analysed. HBL was calculated according to the linear Gross formula using the patient's average Hct during the perioperative course and PBV...

This systematic review and meta-analysis aimed to provide guidance on preoperative blood transfusion strategies for patients with sickle cell disease (SCD). We included all randomized controlled and observational studies exploring the clinical outcomes of preoperative blood transfusion among patients with SCD compared to the conservative transfusion strategy until 14/09/2022. Sixteen studies involving 3486 participants were analysed. The findings revealed a significantly higher bleeding rate in patients who received preoperative transfusion than those who followed a conservative strategy (RR = 4...

INTRODUCTION: Degenerative cervical myelopathy (DCM) is a form of chronic spinal cord injury, with a natural history of potential for progression over time. Whilst driven by mechanical stress on the spinal cord from degenerative and congenital pathology, the neurological phenotype of DCM is likely to be modified by multiple systemic factors. The role of metabolic factors is therefore of interest, particularly given that ischaemia is considered a key pathological mechanism of spinal cord injury...

UNLABELLED: Total knee arthroplasty (TKA) is the most cost-effective, and potent method for the treatment of end-stage knee osteoarthritis. Acute normovolemic haemodilution (ANH) can effectively replace the need for allogeneic transfusions due to the high amount of bleeding during TKA. However, more studies are needed to prove the efficacy and safety of ANH and to clarify its indications in the field of knee replacement. Medical records from June 1, 2019 to June 1, 2021 were searched and grouped according to inclusion and exclusion criteria...

AIMS: Hip fractures are some of the most common fractures encountered in orthopaedic practice. We aimed to identify whether perioperative hypotension is a predictor of 30-day mortality, and to stratify patient groups that would benefit from closer monitoring and early intervention. While there is literature on intraoperative blood pressure, there are limited studies examining pre- and postoperative blood pressure. METHODS: We conducted a prospective observational cohort study over a one-year period from December 2021 to December 2022...

OBJECTIVES: To compare the independent and combined effects of anaemia and red blood cell transfusion on late survival after isolated coronary artery bypass grafting (CABG). METHODS: Retrospective analysis of 5243 consecutive patients undergoing primary isolated CABG, performed from 2000 to 2015, in a Portuguese Academic Hospital. We identified 1649 patients with preoperative anaemia (A+) and 1422 patients who received a perioperative transfusion (T+) - the four possible combinations allowed for the creation of four subgroups (A-/T-, A-/T+, A+/T-, and A+/T+)...

Introduction Post-operative anaemia in hip fracture patients has been associated with increased risk of blood transfusion, poorer functional outcomes, increased morbidity and mortality. Patients with persisting drop in haemoglobin after fractured neck of femur with no obvious source of blood loss are often referred for endoscopy to find the cause of anaemia. The reported incidence of perioperative acute upper gastrointestinal bleeding varies from 1 to 15%. Objective The aim of our study is to find out the usefulness of endoscopy in finding gastrointestinal causes leading to the occult loss of blood causing irreversible anaemia in post-operative neck of femur fractures...

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...

Caesarean section has risks of bleeding, infection and thromboembolism, and neuroendocrine-metabolic, and inflammatory-immune responses that may worsen outcomes in patients with preeclampsia. There is little research examining perioperative, as opposed to peripartum, outcomes in patients with preeclampsia. We conducted a single-centrecentre retrospective cohort study of perioperative patients with preeclampsia over an eight-month period to determine the rate of perioperative complication. Seventy-two patients were included...

INTRODUCTION: Iron-deficiency anaemia is common in gynaecological oncology patients. Blood transfusions are immunosuppressive and carry immediate and long-term risks. Oral iron replacement remains the standard of care but requires prolonged treatment courses associated with gastrointestinal side effects, poor compliance and variable absorption in cancer patients. Intravenous iron has been shown to decrease the need for allogeneic blood transfusion in gynaecological oncology patients undergoing chemotherapy, but the efficacy of this treatment in the preoperative period is unknown...

INTRODUCTION: In immunotherapy, antibodies are activated to block immune checkpoints, resist tumour immunosuppression, shrink tumours and prevent a recurrence. As the science behind tumour immunotherapy continuously develops and improves, neoadjuvant immunotherapy bears more prominent advantages: antigen exposure not only enhances the degree of tumour-specific T-cell response but also prolongs the duration of actions. In this study, we evaluated the efficacy and safety of McKeown minimally invasive oesophagectomy (McKeown MIO) following neoadjuvant immunotherapy combined with chemotherapy (NICT) in patients with locally advanced oesophageal cancer (OC)...

INTRODUCTION: In view of the shortened length of hospital stay following THA, an increasing proportion of patients have required transfer to "extended-care" (ECF) or "skilled nursing" facilities (SNF) over the past years. As a result, the expenditure related to postoperative care facility has been acknowledged as a crucial component of total economic burden associated with THA. In this context, the clinical and demographic factors leading to the need for transfer of patients to SNF following primary THA need to be clearly understood...

BACKGROUND: Increasing expectancy of life and levels of activity in the growing geriatric population lead to a rising number of prosthetic implants of the hip and consequently the incidence of periprosthetic fractures of the femur increase. The fracture pattern and the possible instability of the stem are a challenge to the orthopaedic surgeon. Treatment options are complete replacement of the implant or a solitary osteosynthesis. The goal of this study was to analyse the feasibility of the operative intervention using a contralateral reversed anatomic distal femoral LISS® locking plate and the radiological and functional outcome in a geriatric cohort...

AIMS: Blood transfusion and postoperative anaemia are complications of total knee arthroplasty (TKA) that are associated with substantial healthcare costs, morbidity, and mortality. There are few data from large datasets on the risk factors for these complications. METHODS: We retrospectively reviewed the records of TKA patients from a single tertiary care institution from February 2016 to December 2020. There were a total of 14,901 patients in this cohort with a mean age of 67...

INTRODUCTION: This retrospective observational study aimed to evaluate the feasibility and effectiveness of complete revascularization coronary artery bypass grafting (CABG) in patients with multi-vessel disease (MVD)-CAD and declined renal functions, addressing the knowledge gap regarding optimal treatment strategies and outcomes in this specific patient population. METHODS: Between 2020 and 2022, a total of 58 patients underwent on-pump coronary artery bypass grafting surgery for complete myocardial revascularization in this study...

BACKGROUND: Perioperative red blood cell transfusion is a double-edged sword for surgical patients. While transfusion of red cells can increase oxygen delivery by increasing haemoglobin levels, its impact on short- and long-term postoperative outcomes, particularly in patients undergoing elective major abdominal surgery, is unclear. METHODS: We conducted a systematic review and meta-analysis on the effect of perioperative blood transfusions on postoperative outcomes in elective major abdominal surgery...
