Summary

This study tested a non-invasive blood pressure monitor (CNAP) against the standard invasive method (using a needle in the artery) in 20 pregnant women with placenta accreta undergoing scheduled C-sections. The goal was to see if the gentler method gives equally accurate readings to help doctors make safer decisions during surgery. The study was terminated early, so results are limited.
