Research Abstract

Postoperative delirium is a common problem that is associated with prolonged hospitalization. The objective of this study was to examine whether the postoperative delirium crisis rate can be reduced by bright light therapy. Fifty-five patients were randomized the study group that was exposed to light (1.500-2000lx) during the first three post operative days for 2h in the morning or control group that was placed in a natural lighting environment. A significant difference was observed in the delirium score(J-NCS) and sleep-awake rhythm between the study group and control group on the post operative 1 day. Bright light therapy may reduce the rate of postoperative delirium.
