How long can delirium recover after heart valve surgery

The duration of recovery from confusion after heart valve surgery varies from individual to individual, and there is no accurate time value.

Confusion after heart valve surgery may be caused by residual effects of anesthetics. Some patients may metabolize anesthetics faster, generally recovering in about 2 hours. Some patients with slower metabolism of anesthetics may take about 6 hours to recover. Secondly, this manifestation may also be caused by brain hypoxia during surgery. For patients with less severe hypoxia, it may recover within a few days. If the hypoxia is severe, it may take weeks or longer to recover.
