What is the effect of preoperative aspirin on bleeding in CABG patients?
Preoperative aspirin doses of 325 mg were associated with increased bleeding (mean difference, 230 mL), whereas those who received 325 mg preoperatively did not have a significant increase in blood loss (mean difference: 65.3 mL; 95% CI: 20.2 to 150.8; P 0.134).
