Effects of Sevoflurane Anesthesia on Spatial Memory in Adults

Study of the Effect of Sevoflurane General Anesthetic on Spatial Memory in Humans

Observational University of Chile · NCT05991817

This study is testing how sevoflurane anesthesia during gallbladder surgery affects memory in adults by having them complete a virtual maze before and after the procedure.

What this trial studies

This observational study aims to investigate how general anesthesia with sevoflurane affects spatial memory in adults undergoing elective laparoscopic cholecystectomy. Participants will complete a virtual maze test and have plasma samples collected before and after surgery to measure inflammatory cytokines. The study seeks to establish a correlation between the inflammatory response induced by surgery and changes in spatial memory performance. By understanding these effects, the research hopes to shed light on postoperative cognitive dysfunction and its underlying mechanisms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30 to 50 who are scheduled for elective laparoscopic cholecystectomy.

Not a fit: Patients with visual or hearing difficulties, neuropsychiatric disorders, or those on centrally acting medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of postoperative cognitive dysfunction in patients undergoing surgery.

How similar studies have performed: While the effects of anesthesia on cognitive function have been studied, this specific approach focusing on spatial memory and inflammatory markers is relatively novel.
