Development of real-time blood viscometry during cardiopulmonary bypass

Blood Filtration During Cardiopulmonary Bypass

Particulate microembolization during extracorporeal circulation is thought to contribute to cerebral, pulmonary and other post-operative complications following cardiac surgical procedures. 11° Factors which have been implicated in microembolic phenomena during cardiopulmonary bypass include: 1 ) transfusion of stored blood ,I· 2 ' '· 11 ' ' 3 22 2) formation of platelet aggregates in the patie...

Cerebral 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...

Myocardial protection of warm blood cardioplegic induction during cardiopulmonary bypass.

In his prospective randomized clinical study, we evaluated the myocardial protection of warm blood cardioplegic induction and cold blood cardioplegic induction, respectively, during cardiopulmonary bypass. Twenty-eight adult patients who underwent valve replacement were randomly divided into two groups: group T (14 cases) received cold (6-8 degrees C) blood cardioplegic induction after ECG show...

Hypoxaemia during cardiopulmonary bypass.

For cardiopulmonary bypass during open-heart surgery we use a bubble oxygenator and a technique of haemodilution and moderate hypothermia. During the course of routine perfusion we have observed arterial desaturation in a number of patients and in five patients the desaturation was marked (SaO2<85%)'. The low arterial oxygen saturations occurred mainly in the rewarming period. This report is of...
