Applying Num Vapocoolant Spray to Cervix Before Paracervical Block to Decrease Pain During Gynecology Procedures

Vapocoolant Application for Pain Reduction During Office-based Gynecologic Procedures: a Randomized Controlled Trial (VAPOR)

The purpose of this study is to assess if Num vapocoolant spray decreases pain associated with paracervical block in gynecology procedures.

After patients seen in our clinic have decided to proceed with a gynecology procedure that requires a paracervical block, the doctor will evaluate if the patient meets eligibility criteria for this study. If the patient does meet eligibility criteria, the doctor will inform the patient about the study and the potential risks. All patients will be given written informed consent. If the patient decides to participate in the study, they will be randomized (patient blinded) to receive either Num vapocoolant spray or placebo (normal saline spray), which the patient will receive during their gynecologic procedure just before the paracervical block. The purpose of this study is to see if the Num vapocoolant spray decreases patients pain with the paracervical block.
