Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Intervention Treatment Group 		Oral placebo and Paracervical Block with combined 1% Lidocaine and Ketorolac
  • Drug: Ketorolac
    Subjects in the treatment group will take oral placebo 30-60 minutes prior to osmotic dilator placement. Immediately prior to placement of osmotic dilators, a 1% lidocaine + ketorolac paracervical block (containing 18 mL of 1% lidocaine combined with 2 mL ketorolac (30mg) will be administered.
  • Drug: Placebo
    Subjects in the treatment group will take oral placebo 30-60 minutes prior to osmotic dilator placement.
  • Drug: Lidocaine HCl 1%
    Immediately prior to placement of osmotic dilators, a 1% lidocaine paracervical block (containing 18 mL of 1% lidocaine combined with 2 mL of saline) will be performed in the following fashion: Two milliliters of the analgesic mixture will be placed at the tenaculum site intracervically. After the tenaculum is placed, the remaining 18 mL of the analgesic mixture will be administered at 4 and 8 o'clock at the cervicovaginal reflection.
Active Comparator
Standard Treatment 		Oral ibuprofen with plain 1% lidocaine paracervical block
  • Drug: oral ibuprofen
    Subjects in the control group will take oral ibuprofen 600mg 30-60 minutes prior to osmotic dilator placement.
  • Drug: Lidocaine HCl 1%
    Immediately prior to placement of osmotic dilators, a 1% lidocaine paracervical block (containing 18 mL of 1% lidocaine combined with 2 mL of saline) will be performed in the following fashion: Two milliliters of the analgesic mixture will be placed at the tenaculum site intracervically. After the tenaculum is placed, the remaining 18 mL of the analgesic mixture will be administered at 4 and 8 o'clock at the cervicovaginal reflection.
  • Drug: Saline
    Immediately prior to placement of osmotic dilators, a 1% lidocaine paracervical block (containing 18 mL of 1% lidocaine combined with 2 mL of saline) will be performed.

Detailed Description

The purpose of this study is to improve pain management for participantswho need osmotic dilators for cervical preparation the day before their second trimester abortion procedure. Osmotic dilators are sticks that are inserted into the cervix. They soak up fluid and expand overnight, gently opening the cervix. We are studying an injection of ketorolac (a liquid anti-inflammatory medication similar to ibuprofen) combined with lidocaine (a liquid numbing medication), which is injected vaginally to the area surrounding the cervix. Ketorolac is approved by the U.S. Food and Drug Administration (FDA) for intravenous (IV) and intramuscular injection and has been studied as a paracervical injection for participants having first trimester abortion procedures in the office. It has not previously been studied for osmotic dilator insertion.
