What this trial studies

This study evaluates the effectiveness of a durometer, specifically a Shore durometer, to quantitatively measure uterine tone in patients undergoing scheduled cesarean deliveries. The research aims to validate this instrument against the commonly used qualitative scoring scale for uterine tone, which has shown good reliability in previous studies. By comparing the durometer measurements with clinical assessments, the study seeks to establish a more accurate method for assessing uterine tone during cesarean sections.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring of uterine tone, potentially reducing complications associated with cesarean deliveries.

How similar studies have gone: While some studies have explored the use of durometers for measuring uterine tone, this specific application in cesarean delivery is novel and has not yet been validated.
