Abstrakt: Background: Anaemic cardiac surgery patients are at greater risk of intraoperative red blood cell transfusion. This study questions the application of the World Health Organization population-based anaemia thresholds (haemoglobin <120 g L -1 in non-pregnant females and <130 g L -1 in males) as appropriate preoperative optimisation targets for cardiac surgery.
Methods: A retrospective cohort study was conducted on adults ≥18 yr old undergoing cardiopulmonary bypass surgery. Logistic regression was applied to define sex-specific preoperative haemoglobin concentrations with reduced probability of intraoperative red blood cell transfusion for cardiac surgery patients.
Results: Data on 4384 male and 1676 female patients were analysed. Binarily stratified multivariable logistic regression odds of receiving intraoperative red blood cell transfusion increased in cardiac surgery patients >45 yr old (odds ratio [OR] 1.84; 95% confidence interval [CI] 1.33-2.55), surgery urgency <30 days (OR 2.03; 95% CI 1.66-2.48), combined coronary artery bypass grafting and valve surgery, or other surgery types (OR 2.24; 95% CI 1.87-2.67), and female sex (OR 1.92; 95% CI 1.62-2.28). The odds decreased by 8.4% with each 1 g L -1 increase in preoperative haemoglobin (OR 0.92; 95% CI 0.91-0.92). Logistic regression predicted females required a preoperative haemoglobin concentration of 133 g L -1 and males 127 g L -1 to have a 15% probability of intraoperative transfusion.
Conclusions: The World Health Organization female anaemia threshold of haemoglobin <120 g L -1 disproportionately disadvantages female cardiac surgery patients. A preoperative haemoglobin concentration ≥130 g L -1 in adult cardiac surgery patients would minimise their overall probability of intraoperative red blood cell transfusion to <15%.
