What this trial studies

This clinical trial investigates the effects of subanesthetic doses of esketamine on sleep quality in patients undergoing modified radical mastectomy for breast cancer. A total of 184 participants will be enrolled, and their sleep quality will be assessed using various scales before and after surgery. The study aims to understand how esketamine can mitigate postoperative sleep disturbances, which are common in patients undergoing surgery after neoadjuvant chemotherapy. Blood samples will also be collected to analyze potential biomarkers related to sleep and inflammation.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 65 with a diagnosis of breast cancer who are receiving neoadjuvant chemotherapy.

Not a fit: Patients with a BMI over 30, cognitive dysfunction, or severe organ dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve sleep quality and recovery outcomes for breast cancer patients undergoing surgery.

How similar studies have performed: While the use of esketamine for sleep disturbances is a novel approach, similar studies have shown promising results in managing postoperative pain and anxiety.
