Microemboli detection on extracorporeal bypass circuitsa

摘要: Numerous authors have associated gaseous microembolization with adverse cerebral outcomes during cardiopulmonary bypass (CPB). The introduction to this review provides background on the connection between microemboli and outcomes. This is often difficult quantify, as depend a number of factors, including size bubble, where it passes through patient, patient comorbidities other factors. Nonetheless, numerous studies shown statistically significant differences in mean emboli detected patients that stroked those did not, well for major cardiac complications longer length hospital stay. Our followed by case reports laboratory showing how monitoring (GME) can be used reduce embolic load delivered circuit. These methods include improved qualification circuit design prior surgery, modification priming procedures air at start new injecting drugs into better detection removal sources surgery. concludes ultrasonic GME, comparing through-transmission gross detectors Doppler ultrasound technology fixed-beam imaging emboli, technique images moving blood using single transducer element fixed position. overview meant shed light why different technologies report widely varying counts loads, represents an improvement ability monitor, measure quantitate CPB.
