Factors Associated With Quality of Dreams During General Anesthesia

Factors Associated With Quality of Dreams During General Anesthesia: a Prospective Observational Study

Patients frequently report having dreams during general anesthesia. The incidence of dreams during general anesthesia that have been reported by patients upon awakening has been reported to range from 10 to 36% [1] and to be higher in younger patients, female patients [2], and patients who received ketamine [3]. The quality of dreams during general anesthesia is often reported as pleasant, but some patients report unpleasant or not pleasant dreams [4, 5]. However, the factors associated with the quality of dreams have remained to be elucidated. Therefore, the aim of this study was to determine the relationships between the quality of dreams during general anesthesia and perioperative factors.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Anesthesia information	Anesthesia was maintained with a general anesthetic (propofol, sevofurane, or desfurane) and remifentanil. Some patients also received a peripheral nerve block. Anesthetic management including the choice of a general anesthestic (propofol, sevofurane, or desflurane) depended on the decision of the anesthesiologists in charge	During the operation
Dream interview	The following questions were asked.; What was the last thing you remember before going to sleep?; What was the frst thing you remember from when you woke up?; Can you recall anything between?; Did you have any dreams while under anesthesia?; How did you feel about your dream: pleasant, indiferent or unpleasant?	After extubation, patients were interviewed about intraoperative dreams in the operating room as soon as they were oriented to time, place, and person
Depression level	The Hospital Anxiety and Depression Scale (HADS), which is a self-report questionnaire, was used for evaluation of anxious and depressive states in the participants	the day before surgery
