The effect of preoperative aspirin-free interval on red blood cell transfusion requirements in cardiac surgical patients

Association Between Preoperative Aspirin-dosing Strategy and Mortality After Coronary Artery Bypass Graft Surgery

“…Moreover, recent studies have shown that stopping ASA within 3 days did not result in increased bleeding when compared with 7 days. 11,30 This may enable patients to continue receiving the benefits of ASA therapy until surgery without the concern for increased bleeding complications. 31,32 Second, when compared with the earlier studies, patients today are typically older, present with more comorbidities, are more likely to have coronary stents, and are on chronic ASA therapy.…”

“…Nevertheless, the rates of reoperations for bleeding were similar in all groups and were comparable to recently published data, suggesting that the bleeding and transfusion requirements may not have differed significantly. 14,15,30,31 Lastly, we did not measure or control for the effect of postoperative ASA administration, although standard practice at the THI is for all patients to begin ASA within 1 day after surgery.…”

Antiplatelet therapy preceding coronary artery surgery

“…Weightman and colleagues [30] compared the effect of different lengths of aspirin withdrawal, prior to CABG, using similar APT free intervals as performed in our study. Only patients who stopped taking aspirin ,3 days had increased transfusion demands.…”

Robotic cardiac surgery: an anaesthetic challenge

“…Construction of distal anastomosis involves the use of a myocardial stabiliser designed to isolate a small segment of myocardium with the relevant coronary artery, and proximal and distal silastic sutures to control back-bleeding 32. Intracoronary shunts are often used to facilitate anastomosis construction and maintain distal perfusion, particularly to the target vessel that the myocardium perfusion still depends on.…”
