Brief summary
Recent studies have shown that positive preoperative suggestions can significantly influence the quality of dreams and reduce the incidence of unpleasant dreams during sedation with agents like ketamine and propofol.
Detailed description
Cheong et al. demonstrated that a simple positive suggestion before ketamine administration could reduce unpleasant dreams, while Kim et al. found that propofol, compared to midazolam, led to more vivid and memorable dreams, along with similar satisfaction levels in patients. This study aims to extend these findings by comparing the effects of propofol and ketamine sedation on dreaming during anesthesia, with a focus on how preoperative suggestions might influence dream content, emotional tone, and patient satisfaction.

| Measure | Time frame | Description |
|---|---|---|
| Satisfaction with Care | Satisfaction will be assessed immediately after full awakeness in the Post-Anesthesia Care Unit (PACU) | A 101-point numerical rating scale included in the Dreaming and Cognition Evaluation Questionnaire will be used to measure patient satisfaction with the overall care and sedation experience. |
| Adverse events | Monitoring will be continuous with regular vital signs recorded every 5 minutes during surgery and every 15 minutes in the PACU. | Any complications such as hypotension,or bradycardia, will be recorded systematically. |
