What the study is about

The goal of this research study is to learn more about how different uses of a numbing medication might affect pain levels while getting an IUD placed. The investigators are also studying participants opinions of their clinicians' empathy.

The investigators are inviting patients who arrive at their clinic visit seeking an IUD.

Usually, at University of California, San Diego (UCSD), for patients who have never delivered a baby, clinicians use a buffered paracervical block for before IUD placement. The purpose of this research study is to investigate whether a "buffered" (2 cc of sodium bicarbonate, 18 cc of 1% lidocaine) paracervical block (numbing medication given on both sides of the cervix) is effective in reducing pain during IUD placement in individuals with prior C-sections, the difference between buffered and unbuffered for nulliparous patients, and whether a medicated gel reduces pain with the paracervical block.

Being studied: Buffered Lidocaine; Sham Comparator; Unbuffered lidocaine; Xylocaine jelly 2%; Surgilube

Conditions: Contraception; Pain, Acute; Anesthesia, Local
