ClinConnect Summary
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.
