Postoperative Sleep Disturbances After Zolpidem Treatment in Fast-track Hip and Knee Replacement

August 7, 2012 updated by: Lene Krenk, Rigshospitalet, Denmark
Sleep after surgery has been found to be very distrubed immediately after major surgery. This is also seen after fast-track hip and knee replacement with length of stay of less than 3 days. Disturbed sleep has many adverse effects i.e. fatigue, possible hyperalgesia and decline in cognitive abilities.
