Pulsatile perfusion during cardiopulmonary bypass

Clinical comparison of pulsatile and nonpulsatile perfusion during cardiopulmonary bypass.

Controversy exists concerning the utilization of pulsatile flow during cardiopulmonary bypass (CPB) with regard to improved patient outcomes. The purpose of the present study was to evaluate pulsatile perfusion in patients undergoing CPB in a clinical setting. Seventy patients undergoing open heart surgery for repair of valvular or congenital heart disease were prospectively entered into the st...

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...

Pulsatile flow during cardiopulmonary bypass preserves postoperative microcirculatory perfusion irrespective of systemic hemodynamics.

The onset of nonpulsatile cardiopulmonary bypass is known to deteriorate microcirculatory perfusion, but it has never been investigated whether this may be prevented by restoration of pulsatility during extracorporeal circulation. We therefore investigated the distinct effects of nonpulsatile and pulsatile flow on microcirculatory perfusion during on-pump cardiac surgery. Patients undergoing co...

Pulsatile Flow During Cardiopulmonary Bypass: Is it Beneficial?

____________ _ (}. Extra-Corpor. Techno/. 20[ 1]: p. 24-29, 60 references, Spring 1988) Pulsatile perfusion has been a topic of great controversy for many years. This paper reviews historical aspects of pulsatile perfusion, as well as current and conceptual aspects of pulsatile perfusion. The positive and negative points of pulsatile perfusion are discussed so the reader may draw conclusions in...
