Cerebral microemboli during cardiopulmonary bypass: increased emboli during perfusionist interventions Ruth L Taylor, MSc, Michael A Borger, MD, Richard D Weisel, MD, Ludwig Fedorko, MD, PhD, Christopher M Feindel, MD The Annals of Thoracic Surgery Volume 68, Issue 1, Pages 89-93 (July 1999) DOI: 10.1016/S0003-4975(99)00475-0

Fig 1 Rate of microemboli detection during surgical interventions, perfusionist interventions, and baseline (see text for definitions). Perfusionist interventions resulted in a significantly higher rate of emboli production. The Annals of Thoracic Surgery 1999 68, 89-93DOI: (10.1016/S0003-4975(99)00475-0)

Fig 2 Proportion of total microemboli detected during each event. Drug injections and blood sampling (perfusionist interventions) resulted in a higher proportion of emboli than other events. (Aorta cann, Aorta decann = aortic cannulation and decannulation; CPB = cardiopulmonary bypass; Eject = start of cardiac ejection after cross-clamp removal; XCL = cross-clamp.) The Annals of Thoracic Surgery 1999 68, 89-93DOI: (10.1016/S0003-4975(99)00475-0)

Fig 3 Rate of microemboli detection during each surgical intervention. Initiation of cardiopulmonary bypass (CPB on) and start of cardiac ejection after cross-clamp removal (Eject) resulted in higher rates of emboli production than other surgical events. Other abbreviations are the same as in Figure 2. The Annals of Thoracic Surgery 1999 68, 89-93DOI: (10.1016/S0003-4975(99)00475-0)

Fig 4 Rate of microemboli detection during perfusionist interventions. Drug injection resulted in a higher rate of emboli production than blood sampling or any other period examined. The Annals of Thoracic Surgery 1999 68, 89-93DOI: (10.1016/S0003-4975(99)00475-0)
