Brief Summary

This observational, questionnaire-based study aims to evaluate health professionals' perceptions regarding the potential subconscious effects of intraoperative conversations on patients. Although intraoperative awareness is rare, neuroscientific evidence suggests that unconscious perception of auditory stimuli under anesthesia may influence postoperative psychological outcomes. An anonymous 19-item online survey will be distributed to anesthesiologists, anesthesia residents, anesthesia technicians, surgeons, surgical residents, and operating room nurses across Turkey. Data will be collected via Google Forms, with voluntary participation and informed consent. Statistical analysis will include descriptive and comparative methods to assess differences across professional groups and experience levels.
