Why the study?
Do Surgical Stress Index and Number of Fluctuations in Skin Conductance accurately reflect stress hormone plasma levels and depth of analgesia in patients undergoing elective surgery?
Population
20 patients scheduled for elective surgery
Comparison
Monitoring of intra-operative nociception using… vs Stress hormone plasma levels
Design
Cohort
Follow-up
intra-operative (five time points)

These indices should not guide intraoperative analgesia; leaves open their validity as noradrenaline surrogates in elective surgery.
Do Surgical Stress Index and Number of Fluctuations in Skin Conductance accurately reflect stress hormone plasma levels and depth of analgesia in patients undergoing elective surgery?
Surgical Stress Index and skin conductance fluctuations have poor predictive ability for intra-operative stress hormone levels and depth of analgesia.
Ledowski et al. (2010) studied this question.
