Key result
Neuromonitoring using processed EEG during cardiopulmonary bypass can assess anesthesia delivery adequacy and monitor for pathologic conditions compromising brain function.
Why the study?
Patients undergoing CPB face high risk for inappropriate anesthetic dosing, while traditional physiological indicators are altered by hemodilution, circuit absorption, and altered pharmacokinetics.
Does processed EEG with spectral analysis improve anesthetic management and monitoring in patients undergoing cardiopulmonary bypass?
Does processed EEG with spectral analysis improve anesthetic management and monitoring in patients undergoing cardiopulmonary bypass?
Processed EEG provides valuable neuromonitoring during cardiopulmonary bypass to optimize anesthetic delivery and detect cerebral complications.
Processed EEG may aid perfusionists in assessing anesthesia adequacy and cerebral perfusion during CPB; leaves open impact on outcomes in prospective studies.
Introduction: Since its origin in the 1920s, electroencephalography (EEG) has become a viable option for anesthesia and perfusion teams to monitor anesthetic delivery, optimizing drug dosage and enhancing patient safety. Patients undergoing cardiopulmonary bypass (CPB) are at particular high risk for excessive or inadequate anesthetic doses. During CPB, traditional physiological indicators such as heart rate and blood pressure can be significantly altered. These abnormalities are compounded by rapid changes in anesthetic concentration from hemodilution, circuit absorption, and altered pharmacokinetics. Method: This narrative highlights the use of processed EEG with spectral analysis for anesthetic management during CPB. Conclusion: We emphasize that neuromonitoring using processed EEG during CPB can assess adequacy of anesthesia delivery and monitor for pathologic conditions that can compromise brain function such as inadequate cerebral blood flow, emboli, and seizures. This information is highly valuable for the clinical team including the perfusionist, who regularly diagnose and manage these pathological conditions.
