Abstract

Because the incidence of complications in CNS functioning is reportedly higher in cardiac surgeries requiring CPB than in other types of thoracic surgery without CPB assistance [1], the identification of risk factors has been of major concern in efforts to improve cerebral protection. A review of Barash [2] identified several factors that have been predictive of CNS complications in one or more studies: prolonged hypotension during CPB, overall duration of CPB, age of patient, previous neurological conditions, type and severity of heart disease, and specific components of the CPB process such as pulsatile versus nonpulsatile flow, type of oxygenator, degree and duration of hypothermia, and the use of filters in the circuit.
