Prior to the procedure and study medications, patients will complete patient information and demographics questionnaire and will receive instruction on the 0-100mm visual analogue scale (VAS) and Spielberger State-Trait Anxiety Inventory (STAI). A baseline pain score will be recorded using the 0-100mm VAS with anchors 0 equals no pain and 100 equals worst pain imaginable, as well as baseline anxiety level using the STAI. At placement of the paracervical block and deployment of the second device coil, pain will be assessed again with the same 0-100mm VAS. At 3 to 5 minutes following completion of the procedure, maximal pain experienced during transcervical sterilization will be assessed by the patient. Prior to discharge from the clinic, the patient will rate her pain level using the same 0-100mm VAS, rate her level of anxiety with the procedure using the same STAI, and rate her overall satisfaction with the procedure measured using a 5-point Likert scale.
