Inclusion Criteria

Patients scheduled for elective or urgent surgery under general anaesthesia (including laryngeal mask airway [if planned to be removed in the operating theatre] or endotracheal tube, state entropy monitoring) with sevoflurane. Age: 18 -95 yrs.

Exclusion Criteria

Incapacity to consent, age < 18 yrs, poorly treated diabetes, severe peripheral or cardiac neuropathy, pacemaker, treatment (infusion) with vasoactive medication, ketamine during the data acquisition interval, any intraoperative treatment with ketamine, beta-receptor blockers, clonidine, beta-receptor agonists (i.e. Ventolin) or any other drug suspected to interact with the sympatho-vagal balance.

Primary Outcome Measures

Name	Time	Method
Correlation between surgical pleth index scores during the last 15 min of surgery with the pain scores obtained from patients during the first 15 min of their postoperative recovery. Pain scores will be assessed using a 0 (no pain) - 10 (worst pain) numeric rating scale.[first 15 minutes in the recovery room]

Secondary Outcome Measures

Name	Time	Method
relationship between surgical pleth index and state entropy readings during emergence from anaesthesia[during emergence from anaesthesia]
