Use of Cervical Cap and Menstrual Disc for Application of Topical Anesthetic Prior to IUD Insertion

This prospective, open label, double arm, feasibility group study will recruit participants planning to undergo office intrauterine device (IUD) placement without sedation or anxiolysis at the Center for Women's Health. Participants will self-administer a topical anesthetic using a contraceptive cervical cap or menstrual disc. Twenty-four nulliparous women will be recruited to receive one of two administration methods immediately prior to IUD placement (12 subjects in each arm): 1) menstrual disc filled with 5g eutectic mixture of local anesthetics (EMLA) cream or 2) cervical cap filled with 5g EMLA cream.

Nulliparous patients undergoing IUD insertion will administer EMLA cream by menstrual disc or cervical cap prior to insertion. The medical provider will ensure proper placement of the cap or disc and perform a bi-manual exam to assess the patient's uterine position. A seven minute timer will be set, the cap/disc will be removed, and the provider will proceed with the IUD insertion according to manufacturer technique. Visual Analog Scale (VAS) scores will be used throughout the procedure to assess participant pain throughout insertion. Participants and providers will report on pain, side effects, and procedure complications immediately after the procedure.
