Presentations and discussions during the 2019 Summer MSTCVS-QC's quarterly conference

Meeting topic	Presentations	Discussion: surgeons	Discussion: perfusionists
Physiology of the timing of protamine administration in relation to the termination of cardiotomy suction	(1) Pharmacokinetics of protamine in relationship to activated clotting time; (2) potential risk associated with terminating cardiotomy suction after protamine administration; and (3) interhospital variability in the timing of protamine administration.	Local practice patterns varied from essentially no routine use of cardiotomy suction, with or without the use of autotransfusion devices, to extending the use of pump suckers to some varying time frame beyond the initiation of protamine reversal, particularly during more complex procedures.	Concerns were noted about risking the integrity of the CPB circuit if requiring urgent reinstitution of CPB. Autotransfusion devices are available to process shed blood without contaminating the oxygenator.
