What this trial studies

This interventional randomized control trial aims to evaluate the efficacy and safety of oral pregabalin in controlling postoperative pain in patients undergoing total knee replacement surgeries with regional anesthesia. A total of 120 patients will be randomly assigned to either a pregabalin group, receiving the medication preoperatively, or a control group, receiving no premedication. Both groups will receive standard multimodal analgesia during and after surgery, with their opioid consumption monitored to assess pain control effectiveness. The study seeks to determine if pregabalin can reduce the need for opioids post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 who are undergoing elective total knee replacement under regional anesthesia.

Not a fit: Patients with chronic pain conditions, severe comorbidities, or those undergoing general anesthesia may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved pain management and reduced opioid consumption for patients after knee replacement surgery.

How similar studies have performed: Previous studies have shown that pregabalin can be effective in managing postoperative pain, suggesting potential success for this approach.
