NCT00438035

Brief Summary

Postoperative pain stimulates the autonomic nervous system, induces the production of pro-inflammatory substances, reduces patient mobility and impairs vital functions. The ECG spectral analysis (ECGs) is a non-invasive marker of the autonomic nervous system state. To our knowledge, the correlation between the sympathovagal activity quantified by a non invasive method and the postoperative pain, has not been studied before.
