Comparing Skin Conductance and Nol-index

Nociceptive Monitoring With Skin Conductance and Nol-index in Moderate-to-high Risk Cardiovascular Patients

Comparison of twà different nociception monitors during general anesthesia

Study Overview

• Status: Unknown
• Conditions: Vascular Diseases; Analgesia; Anesthesia; Cardiac Disease; Monitoring
• Intervention / Treatment: Device: Nol-Index; Device: Skin Conductance

Detailed 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).

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Patients undergoing general anesthesia; Patients are monitored with Nol-Index, skin conductance, and antinociception-index	Device: Nol-Index; Multiparametric monitor that studies that establishes an index as a surrogate to nociception; Other Names: PMD-200; Device: Skin Conductance; Measures skin conductance as a surrogate to nociception; Other Names: The PainMonitor Index
