What this trial studies

This study evaluates the effectiveness of using both intrathecal dexmedetomidine and an adductor canal block for managing pain after total knee arthroplasty. The adductor canal block targets specific nerves to provide localized pain relief, while dexmedetomidine offers additional analgesic and sedative effects. The goal is to enhance postoperative pain management, promote early mobilization, and reduce complications associated with knee surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 scheduled for total knee arthroplasty under spinal anesthesia with ASA physical status I-II.

Not a fit: Patients with neurological disabilities, allergies to local anesthetics or dexmedetomidine, or those with obesity (BMI > 30 kg/m2) may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management for patients undergoing total knee arthroplasty.

How similar studies have performed: While this approach combines established techniques, the specific combination of intrathecal dexmedetomidine and adductor canal block for this purpose is relatively novel.
