Prevalence of Sleep Apnea in Patients Presenting for Hip or Knee Replacement Surgery

Completed

• Conditions: Sleep Apnea, Obstructive

• Registration Number: NCT00874822
• Lead Sponsor: University of Nebraska

Brief Summary

The study hypothesis is that the prevalence of obstructive sleep apnea in patients presenting for total knee or total hip arthroplasty is higher than generally suspected. The study will include just one arm and results will be compared to a literature control group. Participants referred for preoperative evaluation will be screened using a standard questionnaire. Those at high risk of obstructive sleep apnea will then undergo a formal overnight sleep study (polysomnography).

Detailed Description

The study hypothesis is that the prevalence of obstructive sleep apnea in patients presenting for total knee or total hip arthroplasty is higher than generally suspected. The study will include just one arm and results will be compared to a literature control group, a study performed by Harrison et al. and published in the December 2003 issue of The Journal of Arthroplasty. Participants referred for preoperative evaluation will be screened using a standard questionnaire. Those at high risk of obstructive sleep apnea will then undergo a formal overnight sleep study (polysomnography). The Berlin questionnaire is being used for screening.
