Arterial 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 کاملA "virtual" blood gas electrode for use during cardiopulmonary bypass.
We describe the development of a “virtual” blood gas electrode system intended for use during cardiopulmonary bypass (CPB). The electrode functions in real time and predicts the patient’s arterial and mixed venous blood gas results every 500 ms. It takes as its primary inputs the settings of the heart-lung machine (FiO2, sweep gas rate, pump flow) and the patient’s hematocrit and metabolic rate...
متن کاملBlood 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...
متن کاملCerebral arterial gas embolism following cardiopulmonary bypass surgery.
A 13-year-old boy with a history of tetrology of Fallot underwent a pulmonary value replacement procedure. Gas bubbles were observed in the bypass circuit during the procedure. Trendelenburg position, one of the older standard recommendations when arterial gas embolism (AGE) is suspected, was established during the remainder of the procedure [1]. The patient could not support respirations adequ...
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...
