Effects of Flumazenil on Recovery After Total Intravenous Anesthesia With Remimazolam in Elderly Patients Undergoing Hip Joint Surgery: a Prospective Randomized Controlled Study.

NA · Pusan National University Yangsan Hospital · NCT05939674

This study tests if using flumazenil after remimazolam anesthesia helps older patients recover faster and reduces memory problems after hip surgery.

What this trial studies

This study examines the necessity of using flumazenil, a reversal agent, after administering remimazolam for total intravenous anesthesia in elderly patients undergoing hip joint surgery. It aims to evaluate the impact of flumazenil on recovery time and the occurrence of postoperative cognitive dysfunction. The research will consider factors such as age, obesity, and plasma albumin levels that may affect recovery. By comparing flumazenil with normal saline, the study seeks to clarify its role in clinical practice.

Who should consider this trial

Good fit: Ideal candidates are patients over 65 years old scheduled for hip joint surgery.

Not a fit: Patients with impaired consciousness, hemodynamic instability, or certain neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery times and reduced cognitive dysfunction in elderly patients after anesthesia.

How similar studies have performed: While flumazenil is commonly used in clinical settings, this specific investigation into its routine use with remimazolam is novel and has not been extensively studied.
