Abstract:
BACKGROUND AND AIMS: Propofol is a short-acting intravenous sedative-hypnotic agent that can be used as a hypnotics for upper gastrointestinal endoscopy. A study was conducted to evaluate the effectiveness and safety of propofol as a hypnotic agent for upper gastrointestinal endoscopy. METHODS: From June to October 1998, twenty eight patients undergoing upper gastrointestinal endoscopy were to receive propofol. Vital signs and peripheral oxygen saturation (SpO2) were monitored by pulse oximetry during continuous infusion of propofol. Propofol (1% solution) was initially infused by 26.7 mg/kg/hr until loss of eyelash reflex and then titrated to 6-10 mg/kg/hr according to the patient's response and vital sign. Propofol infusion was discontinued while the endoscopic fiber was removed. Recovery time was defined from discontinuation of infusion to positive Romberg test. Evaluation was made from the endoscopists' assessment, patients' satisfaction, patients' recall of the procedure, and consciousness of the patients. RESULTS: It was discovered that systolic, diastolic pressure and heart rate were significantly decreased, compared to control group. But clinically significant changes were not found. Apnea did not exist. And the respiration rate was significantly increased during propofol infusion. Peripheral oxygen saturation (SpO2) was transiently decreased during endoscopy. 14 patients (50%) complained of transient dizziness. Pain and redness over the infusion site was not found. The mean total dose of propofol was 133.6 mg. The mean infusion time of propofol was 6.2 minutes. Mean response and recovery time was 3.7 2.1, 20.9 5.4 minutes. Endoscopists' assessment and patients' comfort for endoscopy were satisfactory. When we asked 28 patients about willingness to undergo the same procedure in the future, 27 patients (96.4%) agreed. Degree of amnesia after examination revealed total amnesia in 27 patients (96.4%), partial amnesia in 1 patients (3.6%), and recall was not. CONCLUSIONS: Propofol has beneficial effects as hypnotic for upper gastrointestinal endoscopy without significant alteration in cardiopulmonary parameters. Patients' and endoscopists' assessment is good. This suggest that propofol may be used more frequently as a kind of premedication, especially in the cases of repeated endoscopy.
