• Lead Sponsor: Women and Infants Hospital of Rhode Island

Brief Summary

This project will be a randomized controlled trial (RCT) measuring pain perception with two different tenaculum placement techniques on the uterine cervix. A tenaculum is an instrument used to hold the cervix (the opening to the uterus or womb) in place. The trial will measure pain perception with a Visual Analog Scale (VAS) from 0 to 100 mm for two different tenaculum placement techniques, fast and slow closure on the uterine cervix. The main objective of this study is to determine if there is a difference in pain perception with fast compared to slow tenaculum placement techniques on the uterine cervix. We hypothesize that the slow technique will be perceived as less painful for subjects as measured on a 0 mm to 100 mm Visual Analog Scale (VAS). Subsidiary objectives include describing overall pain levels during the procedure.

Detailed Description

In order to detect a 15 mm difference on the VAS with two-sided 5% alpha and 80% power and a standard deviation of 33 mm (based on prior studies), a total of 71 subjects per group are required. We aim to recruit 75 subjects per arm in order to account for possible drop out.
