Description of intervention(s) / exposure
Continuous monitoring of the nociception level index (NOL) throughout surgery and monitoring of postoperative pain score for 15 minutes after admission to the recovery room.
NOL is measured via a single-use non-invasive (sticky) electrode on one finger.

Statistical methods / analysis
Statistical analysis: data exploration for normal distribution: K-S Test; investigation of the predictive value of the score: receiver-operating curves for NOL and exploration of the "best-fit" cut-off point with the combined highest sensitivity and specificity (Youden's Index); comparison between pain groups: students T-test, ANOVA or appropriate non-parametric alternatives (if tested non normally distributed).

Summary
Brief summary
The purpose of the study is to identify whether or not the nociception level index (NOL) measured during surgery may allow a prediction of the severity of acute postoperative pain. NOL monitoring is non-invasive and only requires a sticky electrode on one finger. This study aims to observe the relationsship between NOL during surgery and acute postoperative pain in during the first 15 minutes after recovery room admission with the null-hypothesis that NOL in this setting does allow a prediction of pain.
