| Key findings | 27.5% of 200 patients undergoing painless gastroscopy under ciprofol sedation reported dreaming, mostly simple, pleasant dreams about everyday life. Lower ASA grade, preoperative knowledge of the examination, more frequent preoperative dreams, poor preoperative sleep quality, and shorter awakening time were identified as predictors of dreaming, and dreamers showed lower BIS values at 2 minutes after endoscope insertion and after endoscope removal, as well as lower minimum BIS values, than non-dreamers. |
Abstract
Dreaming is often reported by patients who undergo propofol-based sedation, but there have not been any studies to date focused on the incidence of dreaming and factors associated therewith following the administration of ciprofol anesthesia in patients undergoing painless gastroscopy. The present study was thus developed with the goal of assessing the incidence of dreaming. In total, this study enrolled 200 patients undergoing painless gastroscopy. During the procedure, patients' electroencephalographic Bispectral Index (BIS), blood pressure (BP), heart rate (HR), blood oxygen saturation (SpO2), and PETCO2 were monitored. When their MOAA/S score reached five after the procedure, patients were administered questionnaires including the Brice questionnaire and a five-point Likert Scale, and the content of any recalled dreams was also recorded. Overall, 27.5% of the participants in this study reported dreaming during the procedure, with most having experienced simple, pleasant dreams about everyday life. Identified predictors of dreaming during painless gastroscopy included lower ASA grade, preoperative knowledge of painless examination, a higher frequency of dreams in the month before the procedure, poor sleep quality during the month before the procedure, and shorter awakening time. Dreamers showed significantly lower BIS values at 2 min after endoscope insertion and following endoscope removal, and also showed lower minimum BIS values compared with non-dreamers. The postoperative dream recall incidence in this study was 27.5% among patients undergoing painless gastroscopy under ciprofol sedation anesthesia.
