Fifty consecutive patients undergoing transabdominal chorionic villus sampling (CVS) and 52 undergoing amniocentesis completed a questionnaire following the procedure to determine the amount of pain they experienced. Mild pain, discomfort only or no pain was reported by 96% undergoing amniocentesis and 90% with CVS. Moderate or severe pain was reported after completion of the CVS by 8% and following amniocentesis by 2%. Both procedures were well tolerated.
五十名连续接受经腹绒毛取样（CVS）的患者和五十二名接受羊膜穿刺术的患者在手术后完成了一份问卷，以确定他们所经历的疼痛程度。接受羊膜穿刺术的患者中有96%以及接受绒毛取样的患者中有90%报告称有轻微疼痛、仅感不适或无疼痛。绒毛取样术后有8%的患者报告有中度或重度疼痛，羊膜穿刺术后有2%的患者报告有此类疼痛。两种手术的耐受性都很好。
