Although effects of general anesthesia on neuronal activity in the human neonatal brain are incompletely understood, electroencephalography provides some insight and may identify age-dependent differences. ⋯ Although evidence gaps were identified, both increasing sevoflurane concentration and decreasing temperature are associated with increasing discontinuity.

Challenge of Neonatal Anesthesia: Which Optimal EEG Target?
-
Intraoperative hypotension might contribute to the development of postoperative delirium through inadequate cerebral perfusion. However, evidence regarding the association between intraoperative hypotension and postoperative delirium is equivocal. Therefore, the hypothesis that intraoperative hypotension is associated with postoperative delirium in patients older than 70 yr having elective noncardiac surgery was tested . ⋯ To the extent of hypotension observed in our cohort, our results suggest that intraoperative hypotension is not associated with postoperative delirium in elderly patients having elective noncardiac surgery.
