상부 위장관 내시경 검사 시 전처치로서의 Propofol의 효과 = Propofol as Premedication for Upper Gastrointestinal Endoscopy

다국어 초록 (Multilingual Abstract)

Background/Aims: Benzodiazepine is generally used when sedation is required for endoscopy, while propofol, a phenol-derived intravenous anesthetic agent, appears to have a more suitable phamacokinetic profile. The aim of this study was to evaluate the effectiveness and safety of propofol as premedication for upper gastrointestinal endoscopy. Methods: Between July 1998 and October 1998, 44 male patients and 70 female patients were involved in this study. The relative ease of upper gastrointestinal endoscopy, patient's tolerance, and amnestic effects on 64 patients with propofol was compared with 50 patients with non-sedation. Pulse rate and arterial oxygen saturation was monitored. The endoscopist and patients replied to a questionnaire. Results: Patients receiving propofol tolerated endoscopy much more than patients with non-sedation (p＜0.01). The change in pulse rate was less variable but arterial oxygen saturation showed a statistically significant decrease in patients receiving propofol (p＜0.01). Propofoinduced complete amnesia in 93.7% of the patients and partial anesthesia in 4.7%. Most of the patients receiving propofol accepted the same sedative methods in their next endoscopy (p＜0.01). Conclusions: Propofol is highly effective, with a short recovery time and satisfaction of the patients, but careful monitoring is recommended because of its untoward effect of hypoxia. It is recommended that propofol be used as a premedication especially in patients who are apprehensive about a repeated endoscopy.
