Skin conductance as a pain assessment tool during chest tube removal: An observational study

Skin conductance variability to assess pain has shown varying results. Skin conductance responses per second (SCR) during a standardized painful stimulus in awake adults may give further understanding of the method's validity. The purpose of this study was to validate the SCR with the visual analogue scale (VAS) for pain (P‐VAS) and anxiety (A‐VAS) during chest tube removal (CTR).
