Dobutamine increases oxygen consumption during constant flow cardiopulmonary bypass.
We have studied the effects of flow and dobutamine on systemic haemodynamic variables, oxygen delivery (DO2) and oxygen consumption (VO2) in 20 patients during cardiopulmonary bypass (CPB) with mild hypothermia (34 degrees C). In a subgroup of seven patients, we also studied the effects on gastric microcirculatory blood flow (MCF) using laser Doppler flowmetry. During CPB, measurements were mad...
متن کاملHypercarbia depresses cerebral oxygen consumption during cardiopulmonary bypass.
No human studies have systematically examined the relations among PaCO2, cerebral blood flow, and the cerebral metabolic rate for oxygen during hypothermic cardiopulmonary bypass. We varied PaCO2 during hypothermic (26-28 degrees C) cardiopulmonary bypass and estimated the cerebral metabolic rate for oxygen by multiplying cerebral blood flow (measured using xenon-133 clearance) by the cerebral ...

متن کاملSmall-dose epoprostenol decreases systemic oxygen consumption and splanchnic oxygen extraction during normothermic cardiopulmonary bypass.
Normothermic, nonpulsatile cardiopulmonary bypass (CPB) impairs systemic and splanchnic oxygen transport and increases gastrointestinal permeability. It is an important therapeutic goal to avoid splanchnic dysoxia during CPB. Small-dose prostacyclin therapy improves splanchnic oxygen transport and microcirculation in septic patients. In this study, we sought to determine if during cardiac surge...
متن کاملOxygen consumption and lactate release by the lung after cardiopulmonary bypass and during septic shock.
OBJECTIVE We sought to determine whether a correlation exists between lung lactate release and lung oxygen consumption by studying adult intensive care patients, either after cardiopulmonary bypass (CPB) or with septic shock. METHODS A prospective observational study of six post cardiopulmonary bypass patients and seven patients with septic shock was performed in an intensive care unit of a m...
