Summary
Pain perception during chorionic villus sampling (CVS) differs by approach and patient factors. Transabdominal CVS is more painful in heavier women, while transcervical CVS is more painful in nulliparous women.
Area of Science:
- Obstetrics and Gynecology
- Pain Management
- Fetal Medicine
Background:
- Chorionic villus sampling (CVS) is a common prenatal diagnostic procedure.
- Understanding pain associated with CVS is crucial for patient comfort and procedural choice.
Purpose of the Study:
- To compare anticipated versus perceived pain during transabdominal and transcervical CVS.
- To identify patient factors influencing pain perception during CVS.
Main Methods:
- Prospective study involving 121 pregnant women undergoing CVS.
- Pain was assessed using a 0-10 visual analog scale (VAS) before and after the procedure.
- Comparison of pain scores between transabdominal and transcervical CVS based on patient characteristics.
Main Results:
- Anticipated pain was similar for both CVS approaches.
- Perceived pain was similar for transabdominal CVS (abdominal wall <4 cm) and transcervical CVS.
- Significantly greater perceived pain was reported for transabdominal CVS in women with abdominal wall thickness >=4 cm and for transcervical CVS in nulliparous women.
Conclusions:
- Transabdominal CVS is associated with increased pain in women with greater abdominal wall thickness.
- Transcervical CVS is associated with increased pain in nulliparous women.
- Pain perception during CVS is influenced by both the procedural approach and patient-specific factors.
