Brief Summary

Nurse-administered propofol sedation has become the standard procedure for colonoscopy in Germany. Although patient satisfaction with this method is high, there is little data about the satisfaction of the examiner and factors that might negatively influence this satisfaction. Often due to the fact that the sedated patient usually expresses pain by movements of the body and paralinguistic sounds the examination has to pause until the next propofol bolus induces a deeper sedation. In order to measure the correlation of examiner satisfaction and negative factors the investigators initiated this prospective observational study. During this study examiner satisfaction and the correlation with observer reported pain (movements and paralinguistic sounds) will be measured. Additionally different biopotentials (electromyography, skin conductance level, body temperature, pulse) of the patient will be recorded during the examination and feature pattern will be correlated to the observer reported pain in order to detect pain before the expression of pain leads to a pause in the colonoscopy examination. Other factors that might influence examiner satisfaction, like duration to reach the caecum and duration of polypectomy will additionally be evaluated.
