Summary

Traditionally, hemodynamic response e.g. pulse and blood pressure are used to evaluate pain in humans who are anesthetized. These values, however, can be affected by factors other than pain response . In this observational study, different types of digital methods are used that can distinguish signs of pain. However, the study aim to collect data and correlate in between different methods to ensure its reliability.
