title: Repeat general anaesthesia, a 6-year follow up.
abstract: OBJECTIVE
  To investigate the number of children who subsequently required further dental general anaesthesia (DGA) following the baseline DGA for exodontia in 1997 over the next 6 year period, and identify any common factors related to these repeat DGAs.
  
  
  METHODS
  A retrospective longitudinal analysis.
  
  
  METHODS
  Records from a UK teaching hospital for patients who had extractions under DGA within the calendar year of 1997 were identified and analysed. The individual's demographic details, reasons for the baseline DGA, teeth extracted, number of subsequent DGAs, the reasons for repeat DGA and finally any episodes of pain and/or infection after 1997 were recorded.
  
  
  RESULTS
  During 1997, a total of 484 children with mean age of 6.35 (ranged between 1 and 16 years) received a DGA for exodontias. The most common reason for the exodontias carried out at this baseline DGA was dental caries and mean number of exodontias was 4.24. Of the total study population 8.9% subsequently had at least one unplanned repeat DGA, with dental caries being a factor in 84% of the cases. Of the subsequently extracted teeth 71.9% were caries free or unerupted at the time of the initial DGA. Of the children who had a repeat DGA, 61% had experienced at least one episode of pain and/or infection subsequent to the first episode of DGA. The pattern of the child's attendance and the recorded experience of oral pain and infection after the baseline DGA in 1997 were variables proved to be strongly associated with the risk of having an unplanned repeat DGA, with the children who were irregular attenders having a four times increased risk.
  
  
  CONCLUSIONS
  Two common factors were identified which might predict the potential for a child requiring a repeat DGA; irregular attendance and oral pain and infection.
