title: A study of patient attitudes towards fasting prior to intravenous sedation for dental treatment in a dental hospital department.
abstract: BACKGROUND
  Intravenous sedation is the most commonly used method of sedation for the provision of adult dental care. However, disparity exists in pre-operative fasting times in use for patients throughout the United Kingdom.
  
  
  OBJECTIVE
  The aims of the study were to obtain information on the effects of existing extended pre-operative fasting regimens, to canvas patient opinions on the fasting process, and to record their positive and negative experiences associated with it.
  
  
  METHODS
  A prospective cross-sectional descriptive study using survey methodology was conducted of adult patients attending a dental hospital for operative treatment under intravenous sedation. Sixty-four questionnaires were distributed over a four-month period, beginning 2nd October 2007.
  
  
  RESULTS
  The surveyed patient pool consisted of 38 females and 14 males with a mean age of 32.4 years. The response rate achieved was 81.2%. Seventy-one per cent of patients indicated that normally they consumed something for breakfast, the most common items being tea and toast. Fifty-one per cent of patients indicated that they would wish to eat the same as normal prior to their appointment and 59% wished to drink as normal. Only 19% of respondents reported that they did not wish to eat anything, with 8% preferring not to drink anything at all. Seventy-nine per cent of the patients reported that they had experienced at least one adverse symptom after fasting and 42% had experienced two or more such symptoms. In general, those patients with more experience of sedation found fasting less unpleasant than those attending for the first time (P<0.05). In addition, one-quarter of all patients indicated that the fasting process had made them feel more nervous about their sedation appointment.
  
  
  CONCLUSIONS
  The extended fasting regimen prior to intravenous sedation appeared to affect patients' wellbeing, as the majority reported adverse symptoms.
