Esketamine vs. Ketorolac for Prevention of Postoperative Pain and Cognitive Dysfunction After Total Knee Arthroplasty

8 april 2022 uppdaterad av: Guolin Wang, Tianjin Medical University General Hospital

Esketamine vs. Ketorolac for Prevention of Postoperative Pain and Cognitive Dysfunction After Total Knee Arthroplasty in Patients: a Randomized Double-blind Controlled Trial

Purpose:

To compare esketamine and ketorolac separately and in combination to prevent postoperative pain and cognitive dysfunction after total knee arthroplasty

Studieöversikt

Detaljerad beskrivning

With the increase in human life span, orthopedic injuries and subsequent repair surgery have become a major health problem which impairs the life quality of patients and burdens healthcare systems worldwide. Poor post-surgical pain control is a leading factor that hinders the physical rehabilitation and musculoskeletal functional recovery, and causes acute cognitive impairment and chronic pain syndrome. Therefore, prophylaxis of postoperative pain is indispensable to postoperative comfort and satisfaction. There is no denying the fact that pathologic pain is related to central glutaminergic system and N-methyl-d-aspartate (NMDA) receptor activation induced central sensitization. Also, it is previously reported that neuroinflammation is associated with pain development and cognitive dysfunction. Ketamine, a NMDA receptor antagonist, is effective in reversing NMDA receptor activation underlying pain states. But the side effects of ketamine limit its clinical application, such as gibberish and agitation. It is clarified that esketamine has lower side effects than ketamine and that antinociception of esketamine is stronger than ketamine. The following study is carried out to evaluate whether esketamine and ketorolac can prevent postoperative pain and cognitive impairment after total knee arthroplasty in patients.
