Intravenous conscious sedation in patients under 16 years of age. Fact or fiction?

Recently published guidelines on the use of conscious sedation in dentistry have published varying recommendations on the lower age limit for the use of intravenous conscious sedation. There are a large number of dentists currently providing dental treatment for paediatric patients under intravenous conscious sedation. The 18 cases reported here (age range 11-15 years), were successfully managed with intravenous conscious sedation. The experience in this paper is not sufficient evidence to recommend the wholesale use of intravenous conscious sedation in patients who are under 16 years. The fact that a range of operators can use these techniques on paediatric patients would suggest that further study should be carried out in this population. The guidance should be modified to say there is insufficient evidence to support the use of intravenous conscious sedation in children, rather than arbitrarily selecting a cut off point at age 16 years.

Patient-maintained sedation for oral surgery using a target-controlled infusion of propofol - a pilot study.

OBJECTIVE: To assess the safety and efficacy of a new patient-maintained propofol system for conscious sedation in dentistry. DESIGN: Prospective clinical trial SETTING: Department of Sedation, Glasgow Dental Hospital and School, 2001 SUBJECTS AND METHODS: Patients scheduled for oral surgery with conscious sedation. Exclusions included ASA IV -V, inability to use the handset, opioid use and severe respiratory disease. INTERVENTIONS: Patients were given intravenous propofol to a level of 1.0 microg/ml (reducing from 1.5 microg/ml) using a target controlled infusion system, they then controlled their sedation level by double-clicking a handset which on each activation increased the propofol concentration by 0.2 microg/ml. MAIN OUTCOME MEASURES: Oxygen saturation, patient satisfaction, and surgeon satisfaction. RESULTS: Twenty patients were recruited, 16 female and four male. Nineteen patients completed sedation and treatment successfully. Mean lowest oxygen saturation was 94%. No patients were over-sedated. All patients successfully used the system to maintain a level of sedation adequate for their comfort. Patient and surgeon satisfaction were consistently high. CONCLUSIONS: Initial experience with this novel system has confirmed safety, patient satisfaction and surgeon satisfaction.

A survey of the teaching of conscious sedation in dental schools of the United Kingdom and Ireland.

AIM: To assess and compare, for the first time, the quantity and quality of dental undergraduate teaching in conscious sedation in the dental schools of the UK and Ireland. This was achieved using a prospective, questionnaire-based survey. METHODS: Questionnaires were designed to collect information about undergraduate sedation education from teaching staff and final year dental undergraduates at the 16 dental schools in the UK and Ireland. Staff questionnaires were distributed to a nominated sedation teacher at each dental school and sought details of didactic and clinical sedation teaching methods, plus the quantity and perceived quality of sedation teaching. Student questionnaires were distributed to 5th year dental students and enquired about the quantity and quality of clinical sedation teaching received. The survey was undertaken during May-June 1998. RESULTS: Thirteen dental schools returned staff questionnaires (81%). Seven also provided a student response (44%). The proportion of final year students within the 7 schools who returned completed questionnaires was 38%. Sedation teaching was undertaken primarily by oral surgery and paediatric dental departments. Three schools also utilised anaesthetic departments and 2 schools had dedicated dental sedation departments. All but 2 schools provided didactic teaching on sedation (mean: 4.2 lectures, 1.8 seminars). Of the 7 schools which returned staff and student questionnaires, all provided some clinical training using inhalational and intravenous demonstration cases (mean 5.1 and 4.4 cases, per student, respectively). All but one school provided hands-on inhalational sedation experience (mean 2.6 cases per student) but only two schools provided any hands-on intravenous sedation experience. The quantity of hands-on experience was greater at the two dental schools with dedicated dental sedation departments. Across the schools students rated the overall quality of sedation teaching at average or above, but most staff graded the overall quality of teaching at below average. CONCLUSION: Dental undergraduate sedation teaching shows considerable variation across the dental schools surveyed. At most schools students gained little or no hands-on experience in sedation, especially in intravenous techniques. The undergraduate foundation for sedation education must improve if conscious sedation is to become the principal alternative to general anaesthesia in dental practice.

Blindness and partial-sight: aetiological factors and data collection systems.

271 BD 8 Forms completed by consultant ophthalmologists to enable blind and partially sighted patients to be registered by the social services department were analysed for aetiological factors. This set of data for 1982 to 1986 is tabulated and compared with historical and contemporary data for the country as a whole and some data from Strathclyde, Avon and Leicestershire. It is suggested that in order to monitor epidemiological trends in the causation of visual disability, a composite picture for England could be obtained by requiring one district in each of the fourteen English regional health authorities to collect and analyse the local data. Form BD 8 should be revised, simplified and made computer compatible.
