Postoperative Sleep Disturbances After Zolpidem Treatment in Fast-track Hip and Knee Replacement
This trial is active, not recruiting.
|Condition||sleep duration on the first night after surgery|
|Start date||February 2012|
|End date||August 2012|
|Trial size||20 participants|
|Trial identifier||NCT01551485, H-3-2011-022|
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.
|Endpoint classification||efficacy study|
|Intervention model||parallel assignment|
|Masking||double blind (subject, investigator)|
