The effect of muscle relaxants need to be followed during surgery and before waking up the patient, the anesthesiologist has to make sure that the effect of muscle relaxants is gone. For this purpose, anesthesiologists use so called objective neurlmuscular monitors. These monitors stimulate the ulnar nerve in the wrist and examine the evoked muscle response. The aim of this study is to examine the usability of another nerve in the wrist, the median nerve.
