NCT ID NCT06596486

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compared two methods—CoolStick and ethyl chloride spray—for checking how well anesthesia numbs the skin before a planned C-section. 64 pregnant patients were included. The goal was to see which tool works better for measuring numbness to light touch and cold. This was not a test of a new treatment, but a way to improve how doctors assess anesthesia.
