Paracervical Block for Pain Control With Osmotic Dilator Placement

Summary

Cervical dilators are frequently used for preparation prior to second trimester surgical abortion. While their use decreases complications associated with surgical abortion, their placement is often uncomfortable for the patient. Currently there are no proven methods for reducing pain during osmotic dilator placement. The use of numbing medication around the cervix (paracervical block) may decrease this placement pain.
