Dental treatment under sedation requires various sedation depths depending on the invasiveness of the procedure and patient drug sensitivity. Inappropriate sedation depth may cause patient discomfort or endangerment. For these reasons, patient-controlled sedation (PCS) pumps are commonly used. Patients are able to control the sedation depths themselves by pushing the demand button after the practitioner sets up the bolus dose and lock-out time. Dexmedetomidine is an α-2 adrenoreceptor agonist with sedative, analgesic, and anxiolytic properties. It has been widely used for sedation for its minimal respiratory depression; however, there are few studies on PCS using dexmedetomidine. This study assessed the applicability of dexmedetomidine to PCS.

BACKGROUND/AIMS: There is increasing interest in the use of propofol as a sedative agent for colonoscopy. We evaluated the safety and efficacy of the synergistic sedation with midazolam combined with low-dose propofol versus that of midazolam alone. METHODS: A total of 56 patients from among those who underwent total colonoscopy between August 2004 and October 2004 were randomly assigned to one of three medication treatment groups. Group A (n=18) received low-dose midazolam (0.03 mg/kg IV) plus propofol, group B (n=19) received high-dose midazolam (0.07 mg/kg IV) plus propofol, and group C (n=19) received high-dose midazolam alone. The patients' vital signs were monitored throughout the course of the study. The recovery time and quality as well as the patients' comfort level were also assessed. RESULTS: There were no significant differences in baseline characteristics among the treatment groups. There were also no differences in the duration and insertion time of the colonoscopy among the three groups. The patients' comfort level and cardiorespiratory parameters during colonoscopy were similar among the three groups. The sedation efficacy and recovery times were also similar among the three groups. CONCLUSIONS: Midazolam combined with low-dose propofol as a sedative for colonoscopy exhibits similar effects on safety, patient' comfort level and recovery time to those of midazolam alone.

BACKGROUND: The technique using target-controlled infusion (TCI) with propofol produces safe intraoperative sedation during regional anesthesia with rapid recovery and high patient satisfaction. The objective of this study was to define the blood propofol concentration necessary for conscious sedation in regional anesthesia patients according to age. METHODS: Sixty patients scheduled to undergo regional anesthesia were allocated into one of three groups according to age, such as group 1 (n = 20): 16 24 yr, group 2 (n = 20): 30 39 yr, group 3 (n = 20): 40 55 yr. Thirty minutes after performing regional anesthesia, TCI of propofol started at a target plasma level of 1 microgram/ml adjusted in steps of 0.2 microgram/ml to maintain a sedation level 3 on a 5-point sedation scale. RESULTS: The mean target concentration was 0.9 microgram/ml (group 1), 0.8 microgram/ml (group 2), 0.7 microgram/ml (group 3). The mean propofol consumption was 38.5 microgram/kg/min (group 1), 34.3 microgram/kg/min (group 2), and 30.8 microgram/kg/min (group 3). The recovery time was significantly delayed in group 3 (2.8 min) compared to group 1 (1.5 min) and group 2 (1.8 min). CONCLUSIONS: TCI of propofol within at 0.7 0.9 microgram/ml blood concentration range produces safe intraoperative sedation during regional anesthesia with rapid induction, rapid recovery and high patient satisfaction without severe complications in 16 55 yr old patients.

BACKGROUND: Evidence-based clinical practice guidelines (CPGs) are defined as “statements that are scientifically reviewed about evidence and systematically developed to assist in the doctors' and patients' decision making in certain clinical situations.” This recommendation aims to promote good clinical practice for the provision of safe and effective practices of conscious sedation in dentistry. METHODS: The development of this clinical practice guideline was conducted by performing a systematic search of the literature for evidence-based CPGs. Existing guidelines, relevant systematic reviews, policy documents, legislation, or other recommendations were reviewed and appraised. To supplement this information, key questions were formulated by the Guideline Development Group and used as the basis for designing systematic literature search strategies to identify literature that may address these questions. Guideline documents were evaluated through a review of domestic and international databases for the development of a renewing of existing conscious sedation guidelines for dentistry. Clinical practice guidelines were critically appraised for their methodologies using Appraisal of guidelines for research and evaluation (AGREE) II. RESULTS: A total of 12 existing CPGs were included and 13 recommendations were made in a range of general, adult, and pediatric areas. CONCLUSION: The clinical practice guidelines for conscious sedation will be reviewed in 5 years' time for further updates to reflect significant changes in the field.
