Comparison of twà different nociception monitors during general anesthesia

Full description

Analgesia remains a challenge in anesthesia. Several monitors have shown potential in detecting insufficient analgesia during general anesthesia, but they have not been investigated in patients undergoing cardiac and vascular surgery. In this study, we will compare skin conductance (Medstorm, Norway) and nol-index (Medasense, Israel) w during noxious and non-noxious stimuli. This study is carried out on patients included in another study (Nol-Index Guided Remifentanil Analgesia Versus Standard Analgesia During Moderate-to-High Risk Cardiovascular Surgery).
