Objective: Professional standards recommend stopping cardiotomy suction at the termination of cardiopulmonary bypass before protamine administration based on perceived safety concerns. This study evaluated a multidisciplinary collaborative quality-improvement intervention promoting this agreed-upon cardiotomy suction practice during coronary artery bypass grafting (CABG).
Methods: A statewide intervention (eg, unblinded surgeon and perfusionist feedback, evidence-based lectures, evaluating barriers to change) involved 32 centers participating in the PERForm (ie, Perfusion Measures and Outcomes) Registry to standardize cardiotomy suction practices at cardiopulmonary bypass termination during CABG. Four non-Michigan registry participating centers were not exposed to collaborative learning. Cardiotomy suction practice was defined as the absence of or stopping cardiotomy suction before protamine administration. The practice changes attributed to the intervention, including Michigan and non-Michigan comparisons, were evaluated with the change of time effect modeled using splines. Multivariable regression was used to evaluate the intervention's associated impact (eg, mortality, reoperation, transfusion).
Results: Among 10,394 patients undergoing CABG at Michigan centers, 80.7% achieved agreed-upon cardiotomy suction practices. The Michigan centers had nonsignificant changes in agreed-upon cardiotomy suction practices during the preintervention period ( = .24), with significant increased monthly change in practice thereafter, absent adjusted morbidity and mortality increases. The Michigan centers achieved a significantly greater adjusted monthly improvement in agreed-upon practices relative to non-Michigan centers within 7 months after the intervention (adjusted odds ratio for change of trends: 2.53, < .001).
Conclusions: This initiative demonstrates the effectiveness of multidisciplinary collaborative quality improvement in advancing agreed-upon cardiotomy suction practices without negatively impacting clinical outcomes.

Introduction: Cardiotomy suction blood is used in cardiopulmonary bypass (CPB) surgery to maintain blood volume in the CPB system, although it is known to contain micro emboli, cytokines and free plasma hemoglobin. Our aim was to investigate whether cell saver washing the cardiotomy suction blood before re-transfusing it is safe.
Methods: This is a retrospective study of 1671 elective coronary artery bypass patients, 209 of whom had their pericardial blood processed in a cell saver (Ce-S group).

Bivalirudin anticoagulation for cardiopulmonary bypass during cardiac surgery.

Introduction: Heparin is the primary anticoagulant for cardiopulmonary bypass (CPB) support during cardiac surgery. While widely used, ∼2% of cardiac surgery patients develop heparin-induced thrombocytopenia (HIT) and 4-26% develop heparin resistance. Bivalirudin is an alternative anticoagulant mainly used for percutaneous coronary interventions.

Article Synopsis
- Central aortic cannulation is a technique used during heart surgery to deliver oxygenated blood via a heart-lung machine, but disruptions to this cannula, although rare, can lead to serious complications like bleeding and cardiac arrest.
- A specific case is reported where the cannula's metal tip detached during a left atrium myxoma removal, causing significant blood loss, which was managed with intraoperative blood salvage techniques.
- To prevent such incidents, thorough pre-procedural inspections of all cardiac devices should be performed and all surgical team members should remain vigilant during operations.

Background: Blood loss is common during surgical procedures, especially in open cardiac surgery. Allogenic blood transfusion is associated with increased morbidity and mortality. Blood conservation programs in cardiac surgery recommend re-transfusion of shed blood directly or after processing, as this decreases transfusion rates of allogenic blood.
