Abstract
Despite the acceptance of extracorporeal circulation as an effective modality to facilitate cardiac surgery, patient outcomes can be negatively influenced by the occurrence of perfusion incidents. A perfusion survey was conducted to identify safety techniques and incidents related to cardiopulmonary bypass (CPB). An 80-question survey was mailed to chief perfusionists of all 1030 USA cardiac surgical centers using CPB. The survey was designed to examine practices and incidents that occurred during a 2-year period (July 1996 to July 1998). Five-hundred-and-fifty-two (54% response rate) surveys were returned, which accounted for 797 hospitals (79% of all cardiac centers) and 653 621 surgical procedures. Of the 27 identified CPB safety devices, the highest utilization was arterial line filters (98.5%) and the lowest arterial line bubble traps (3.4%). Of the reported cases, a CPB incident occurred once every 138 cases. The most common occurring incidents were protamine reactions (1:783), coagulation problems (1:771), and heater/cooler failures (1:1809). The rate of occurrence of an incident resulting in a serious injury or death was one for every 1453 procedures. Although techniques and safety devices create a relatively secure environment for CPB, lower incident rates may be achieved with further improvements in coagulation monitoring and incident reporting.
