title: Pain associated with transabdominal chorionic villus sampling--anticipated versus actual.
abstract: OBJECTIVE
  To assess anticipated and perceived pain associated with transabdominal chorionic villus sampling (TA CVS).
  
  
  METHODS
  Sixteen consecutive patients completed 0 (no pain) to 10 (excruciating pain) visual analog scales before and after TA CVS.
  
  
  RESULTS
  Anticipated pain (5.1 +/- 2.9) and perceived pain (5.5 +/- 3.2) were similar (p = 0.42) and moderate. Actual pain was less in five (31%), the same in six (38%), and greater in five (31%) compared to anticipated pain.
  
  
  CONCLUSIONS
  These baseline data are useful for patient counseling and designing interventional trials to decrease procedural pain. TA CVS is associated with moderate perceived pain.
