title: General anesthesia time for pediatric dental cases.
abstract: OBJECTIVE
  The purpose of this study was to describe the use of operating room (OR) time for pediatric dental procedures performed under general anesthesia (GA) at a regional children's hospital over a 2-year period.
  
  
  METHODS
  A cross-sectional review of a pediatric dental  GA records was performed at Seattle Children's Hospital. Data were collected for 709 0- to 21-year-old patients from January 2008 to December 2009. Demographic data, dental and anesthesia operator types, and procedures were recorded. Utilization of OR time was analyzed.
  
  
  RESULTS
  The  mean age of patients was 7.1 years (±4.2 SD), and 58% were male. Distribution by American Society of Anesthesiology (ASA) classifications were: ASA I 226 (32%); ASA II 316 (45%); ASA III 167 (24%). Cases finished earlier than the scheduled time by an average of 14 minutes (±28).  Overrun time was significantly associated with: patient age (P=.01); ASA classification (P=.006); treatment type (P<.001); number of teeth treated (P<.001); and dentist operator type (P=.005).
  
  
  CONCLUSIONS
  Overall, 73% of dental procedures under GA finished early or on time. Significant  variables included patient age, medical status, treatment type and extent, and dentist operator type. Assessing factors that impact the time needed in GA may enhance efficiency for pediatric dental procedures.
