Empathy Through Pain Control: Lidocaine Paracervical Block for IUD Placements

Lidocaine is a drug that has been approved by the Food and Drug Administration (FDA). Sodium bicarbonate is an additive that buffers the acidity of lidocaine. The combination of the two is safe and effective as a paracervical block for pain relief in various OBGYN procedures. At UCSD and other places, it is not currently standard practice for people with prior deliveries birth to receive a paracervical block prior to IUD placement. Participants who take part in this study, may receive an injection of buffered lidocaine (2 cc of sodium bicarbonate, 18 cc of 1% lidocaine), an injection of unbuffered block, and/or lidocaine gel. Throughout the local anesthetic and intrauterine device (IUD) placement procedure, research team members will present participants with questionnaires to complete to assess participants' pain, participants' satisfaction with the procedure, and how much empathy participants feel the clinician has shown.
