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 کاملPlasma heparin activity and antagonism during cardiopulmonary bypass with hypothermia.
Plasma heparin activity in 11 patients undergoing open-heart surgery was measured by comparing thrombin time of patient plasma to thrombin time of plasma containing known heparin concentrations. Although all patients received 300 units/kg of heparin, their initial plasma heparin levels varied significantly, from 1.8 units/ml in lighter petients to 3 units/ml in heavier patients. During hypother...
متن کاملIncreased circulating bradykinin during hypothermia and cardiopulmonary bypass in children.
To determine whether cold could activate the kallikrein-kinin system in vivo as it does in vitro, the circulating systemic concentrations of bradykinin were serially measured in 10 cyildren with congenital diseases of the heart undergoing corrective cardiac surgery. Bradykinin was measured by radioimmunoassay in blood samples obtained before, during and after profound hypothermia (to 18 degrees...
