What this trial studies

This observational study investigates the incidence of connected awareness after intubation and the effects of opioid-free general anesthesia on implicit and explicit memorization during laparoscopic robotic surgery. It aims to assess postoperative well-being, pain levels, analgesic consumption, patient satisfaction, duration of hospitalization, and the timing of first mobilization. The study will collect data from patients undergoing surgery at a single center, focusing on their experiences and outcomes related to anesthesia without opioids.

Who should consider this trial

Good fit: Ideal candidates include patients undergoing laparoscopic robotic surgery with an ASA score of 1 to 3.

Not a fit: Patients with neurological or psychiatric diseases, memory disorders, head trauma, hearing disorders, or those using CNS-affecting medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of patient experiences and outcomes during opioid-free anesthesia, potentially leading to improved anesthesia practices.

How similar studies have performed: While the approach of opioid-free anesthesia is gaining interest, this specific observational study's focus on implicit and explicit memorization is relatively novel and has not been extensively tested.
