Title: An Evaluation of the Paracervical Block for Pain Control in First Trimester Surgical Abortion
Brief Summary: Many woman undergoing a surgical abortion receive a paracervical nerve block for pain reduction, in which lidocaine (a numbing medication) is injected around the cervix. These injections numb the cervix and possibly the lower part of the uterus. However, the injection can be uncomfortable and it is not well known whether it is effective in reducing pain. The purpose of this study is to determine the level of pain women experience with a surgical abortion and the effect that paracervical block might have on that pain.
