Study to check if a simple monitor can guide fluid therapy in labor
NCT ID NCT07253818
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study was designed to see if a device called ClearSight™, which measures blood flow non-invasively, works as well as an ultrasound in pregnant women at term. The goal was to help doctors give the right amount of fluids during labor, avoiding both too little and too much. However, the study was withdrawn before enrolling any participants, so no results are available.
