What this trial studies

This clinical trial investigates the effects of preoperative oral midazolam on postoperative pain relief in patients with colorectal cancer who experience sleep disturbances or anxiety. A total of 280 participants will be randomly assigned to receive either midazolam or a placebo before undergoing laparoscopic colorectal cancer surgery. The study aims to evaluate whether midazolam can enhance sleep quality, reduce postoperative pain, and expedite recovery. Additionally, it will explore the relationship between midazolam administration and stress reduction in these patients.

Who should consider this trial

Good fit: Ideal candidates are Chinese-speaking adults aged 18-60 with a BMI of 18-30 who are scheduled for non-emergency laparoscopic colorectal cancer surgery and exhibit sleep disturbances or anxiety.

Not a fit: Patients with contraindications for midazolam, severe depressive symptoms, or high risk of obstructive sleep apnea may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve postoperative pain management and recovery for colorectal cancer patients suffering from anxiety or sleep disturbances.

How similar studies have performed: Previous studies have indicated potential benefits of improving sleep quality on postoperative pain, suggesting that this approach may yield positive results.
