Description
Xingyang Liu and co-authors look for a warning sign of confusion after surgery in older patients. Their 2026 study follows 210 patients over age 65 who had planned surgery on the abdomen. The sign they track is blood flow in the neck artery that feeds the brain, watched during the operation.
Delirium, a state of sudden confusion, struck 41 of the patients in the week after surgery. Long spells of low neck artery flow went with a much higher risk of that state. Usual blood pressure readings did not show the same pattern. Flow checks, the authors say, may flag at-risk patients whom pressure checks miss. They call for more trials to test the link.
