Brain function monitoring during off-pump cardiac surgery: a case report

Abstract

Background: Early postoperative stroke is an adverse syndrome after coronary bypass surgery. This report focuses on overcoming of cerebral ischemia as a result of haemodynamic instability during heart enucleation in off-pump procedure.

Cortical and autonomic responses to noxious stimulation during anesthesia in cardiac surgery patients are moderated by preanesthetic blood pressure levels

“…Compared to normotensive individuals, patients with hypertension are characterized by cerebral hypoperfusion and structural brain changes, including reductions in gray matter and white matter hyperintensities (for a review, see Jennings & Zanstra, ). Evidence from cardiac surgery studies also shows that the intraoperative level of cerebral blood flow is associated with the integrity of the afferent somatosensory pathway, based on short somatosensory evoked potential measures (Zanatta et al., ). In particular, N30 and N20/P25 potentials are related to intraoperative perfusion of the anterior and medial brain circulation, whereas P14/N18 and N13 potentials are related to intraoperative perfusion of the posterior brain circulation.…”
