Use of a Durometer to Measure Uterine Tone in Cesarean Delivery
University of Chicago
Summary
This study will evaluate the use of a durometer to measure uterine tone in parturients undergoing cesarean delivery.
Description
The most accurate and precise measure of uterine tone is unknown. The most commonly described in vivo method in the literature is a qualitative numeric scoring scale from 0-10. The 0-10 uterine tone score has demonstrated good and excellent inter-rater reliability between 1 and 2 raters respectively, and good inter-rater agreement. Recent data suggests that the 0-10 uterine tone score is well-correlated with clinical assessments of uterine tone. A handful of studies have used a quantitative "hardness meter", including a Shore durometer, to describe uterine tone in vivo, with promising results…
