title: Paracervical block and elective abortion: the effect on pain of waiting between injection and procedure.
abstract: OBJECTIVE
  Our purpose was to assess the effect on pain and patient satisfaction of waiting between paracervical block and dilation during first-trimester abortions.
  
  
  METHODS
  One hundred ninety-nine women seeking pregnancy termination were randomly assigned to a no-wait group (group 1) and a 3- to 5-minute wait between injection and dilation group (group 2). Subjects rated their pain on a visual analog scale at four times: prior to procedure, with dilation, with aspiration, and 30 to 45 minutes after procedure.
  
  
  RESULTS
  No significant differences were observed in pain or satisfaction ratings reported by group 1 (n = 93) and group 2 (n = 101). A significant decrease in pain with dilation (1.21 cm decrease, P =.009) and aspiration (1.15 cm decrease, P =.0015) was observed among patients who received fentanyl.
  
  
  CONCLUSIONS
  Delay between paracervical injection and dilation during first-trimester abortion does not have an impact on patient pain or satisfaction. Fentanyl decreased pain scores by 20% to 25% during the procedure.
