Dreaming and recall during sedation for colonoscopy

Area of Science:

• Anesthesiology
• Neuroscience
• Psychology

Background:

• Dreaming is common after general anesthesia but understudied during procedural sedation.
• Understanding dreaming during sedation is crucial for patient experience and care.

Purpose of the Study:

• To determine the incidence, predictors, and consequences of dreaming during procedural sedation for colonoscopy.
• To assess the relationship between dreaming, recall, and patient satisfaction.

Main Methods:

• Prospective observational study of 200 patients undergoing elective colonoscopy.
• Patients were interviewed upon emergence to assess dreaming and procedural recall.
• Sedation techniques were determined by the anesthesiologist.

Main Results:

• The incidence of dreaming was 25.5%.
• Dreamers were younger and received higher propofol doses than non-dreamers.
• Procedural recall occurred in 4% of patients, predicted by lower propofol dose.
• Dreamers reported higher satisfaction with care.

Conclusions:

• Dreaming is a frequent occurrence during procedural sedation for colonoscopy.
• Higher propofol doses are associated with dreaming, while lower doses predict recall.
• Experiencing dreams during sedation correlates with increased patient satisfaction.
