Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-75 with degenerative lumbar disease who are scheduled for open primary one- to three-level lumbar fusion.

Probably not a fit

Patients who regularly use sleep aids, have insomnia or sleep apnea, or have a history of complications with zolpidem or opiates may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess whether administering zolpidem, a sleep aid, around the time of lumbar spine fusion surgery can enhance patient-reported outcomes. Patients aged 18 to 75 with degenerative lumbar disease will be randomly assigned to receive either zolpidem or a placebo starting two days before surgery and continuing for five days post-surgery. The focus is on one- to three-level spinal fusion procedures, and the outcomes will be measured based on patient feedback regarding their recovery and pain levels.

Why it matters

Potential benefit: If successful, this approach could lead to improved recovery experiences and outcomes for patients undergoing lumbar spine fusion.

How similar studies have gone: While the use of zolpidem in this context is relatively novel, similar studies exploring the impact of sleep aids on postoperative outcomes have shown promising results.
