About

This study investigates correlation between dreaming in propofol anesthesia and an Observer-rating-scale of facial expression after gastrointestinal endoscopy in adults. It also compares dreamers and non-dreamers in age, BMI, propofol dose, duration of procedure, mean arterial pressure, pulse values and Bispectral index values.

Full description

After Ethical committee approval and written informed consent was obtained, a total of 124 patients undergoing gastrointestinal endoscopy were recruited in the prospective observational study. Anesthesia was maintained using incremental propofol doses until the patient was calm and unresponsive to painful stimuli. Bispectral Index (BIS), blood pressure (BP) and pulse were monitored in typical intervals: before induction, during induction, at the beginning of the procedure, at 2nd, 5th and 10th minute of the procedure, and on emergence. On the emergence of anesthesia, the patient's facial expression was rated numerically (-3 pain, +3 smile). Thereafter patients were asked to rate their dream.

Patients undergoing GI endoscopy at Osijek University Hospital

Description:

Observational study. A total of 130 consecutive patients undergoing gastrointestinal endoscopy were included. The anesthesia was provided with propofol, starting with 0,5 mg/kg, and titrated until a patient was unresponsive to painful stimuli and maintaining spontaneous breathing. The blood pressure, pulse and Bispectral index values were measured in 6 defined points. On the emergence from anesthesia, the patient's facial expression was rated numerically by the investigator.

Treatment:

Drug: Propofol
