Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients undergoing laparoscopic robotic surgery with an ASA score of 1 to 3.
✕Probably 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.

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.
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 gone: 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.
