The use of minimized extracorporeal circuits (MECC) in cardiac surgery is expanding. These circuits eliminate volume storage and bubble trap reservoirs to minimize the circuit. However, this may increase the risk of gaseous micro emboli (GME). To reduce this risk, a venous bubble trap was designed. This study was performed to evaluate if incorporation of a venous bubble trap in a MECC system as compared to our standard minimized extracorporeal circuit without venous bubble trap reduces gaseous micro emboli during cardiopulmonary bypass (CPB). Forty patients were randomly assigned to be perfused either with or without an integrated venous bubble trap. After preliminary evaluation of the data of 23 patients, the study was terminated prior to study completion. The quantity and volume of GME were significantly lower in patients perfused with a venous bubble trap compared to patients perfused without a venous bubble trap. The present study demonstrates that a MECC system with a venous bubble trap significantly reduces the volume of GME and strongly reduces the quantity of large GME (>500 µm). Therefore, the use of a venous bubble trap in a MECC system is warranted.
