Factors Associated With Quality of Dreams During General Anesthesia
An observational study of Dream and General Anesthesia, run by Beijing Friendship Hospital.
Trial summary
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].

About this study
Official title: 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 participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Quality of DreamOther
Patients frequently report having dreams during general anesthesia, and the dreams are often reported to be pleasant dreams.
However, factors associated with the quality of dreams during general anesthesia have not been clarifed. The aim of this study was to determine the relationships between the quality of dreams during general anesthesia and perioperative factors.
This prospective observational study included patients scheduled for elective surgery under general anesthesia.

What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: 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?
Measured: 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
Measured: the day before surgery
