To assess anticipated and perceived pain associated with transabdominal chorionic villus sampling (TA CVS).
Sixteen consecutive patients completed 0 (no pain) to 10 (excruciating pain) visual analog scales before and after TA CVS.
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.
These baseline data are useful for patient counseling and designing interventional trials to decrease procedural pain. TA CVS is associated with moderate perceived pain.
评估经腹绒毛取样（TA CVS）相关的预期疼痛和感知疼痛。
16例连续患者在TA CVS前后完成了0（无疼痛）至10（剧痛）的视觉模拟评分。
预期疼痛（5.1±2.9）和感知疼痛（5.5±3.2）相似（p = 0.42）且为中度。与预期疼痛相比，实际疼痛减轻的有5例（31%），相同的有6例（38%），加重的有5例（31%）。
这些基线数据有助于患者咨询和设计减少操作疼痛的干预试验。TA CVS与中度感知疼痛相关。
