Perfusion Assessment during Cardiopulmonary Bypass
Perfusion assessment during cardiopulmonary bypass can be stratified into global and regional categories. This discussion will cover global assessment and selected regional assessments. Ingoing assumptions for this discussion are: 1. Heart and lung perfusion are “out of the loop” during CPB 2. The oxygenator is delivering adequate O2 and removing adequate CO2 3. Hemoglobin concentration is suff...
متن کاملEffects of mean arterial pressure on cerebral perfusion during cardiopulmonary bypass: a review.
Cardiopulmonary bypass (CPB) remains an essential component of many cardiac surgical procedures. The nonphysiologic nature of CPB flow creates a complex array of challenges, which can threaten optimal perfusion and patient well being. It is easy enough to assert that the perfusionist’s responsibility is to provide enough blood flow to meet the metabolic requirements of the patient’s tissues. In...
متن کاملIs increased perfusion pressure really necessary during cardiopulmonary bypass?
We read with great interest the work by Siepe et al. [1] investigating the effect of increased systemic perfusion pressure during cardiopulmonary bypass on cognitive dysfunction and delirium. In this revolutionary study questioning cerebral autoregulation, they found that maintaining mean perfusion pressure during normothermic cardiopulmonary bypass (CPB) at 80–90 mmHg is associated with less e...
متن کاملArterial Pressure during Cardiopulmonary Bypass
A recent randomized trial of higher versus lower mean arterial pressure (MAP) during cardiopulmonary bypass (CPB) showed that higher MAP on CPB was associated with a lower incidence of overall cardiac and neurologic morbidity and mortality in coronary artery bypass graft surgery (CABG) patients. Cardiopulmonary bypass MAP was controlled pharmacologically while CPB flow was held constant for any...
متن کاملIntraocular pressure during cardiopulmonary bypass.
Intraocular pressure was measured in 24 patients undergoing elective cardiopulmonary bypass surgery. There was a rapid rise when the bypass circulation began, and this was maintained for about 30 minutes. A simultaneous drop in arterial perfusion pressure and packed cell volume occurred. We suggest that marked haemodilution is responsible for this effect, through increased ocular blood flow and...
