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...
متن کاملClinical 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...
متن کاملComplement activation during cardiopulmonary bypass: quantitative study of effects of methylprednisolone and pulsatile flow.
Forty four patients undergoing open heart surgery were divided into three groups. Group 1 (17 patients) underwent routine anaesthesia and surgery; group 2 (17 patients) received two doses of methylprednisolone (30 mg/kg), one during induction of anaesthesia and the other immediately before induction of cardiopulmonary bypass; and group 3 (10 patients) received pulsatile flow while undergoing pu...
متن کاملPulsatile 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...
متن کاملCerebral blood flow during cardiopulmonary bypass.
In a study of the cerebral consequences of cardiopulmonary bypass (CPB), we have assessed cerebral blood flow (CBF) by intra-arterial Xenon 133 clearance, utilising a Novocerebrograph 10a, before, during and immediately following CPB. All patients (n = 51), under the care of a single surgical team underwent elective coronary revascularisation using a standardised anaesthetic and surgical protoc...
