Brief Summary:
After conduction a pilot study pupillary dilation reflex PDR is measured in response to nociceptive stimulation perioperatively
Detailed Description:
An infrared camera of the video pupillometer measures the pupillary dilation reflex PDR in response to incremental nociceptive stimuli The PDR is a robust reflex even in patients under general anesthesia and may provide a potential evaluation of the autonomous nociceptive circuit American Society of Anesthesiologists ASA classification I or II patients undergoing elective surgery under general anesthesia are recruited Enrolled patients perioperative undergo PDR measurement at 2 different standardized times before and after opioid administration generated by an inbuilt pupillary pain index PPI protocol PPI as a surrogate for nociception includes noxious stimulations from 10 up to 60 milli ampere mA until pupil dilation is larger than 13 from baseline diameter Therefore no inappropriate high stimulation is executed
