Overview
Brief Summary
The purpose of this study is to determine how Bispectral index (BIS) and Entropy EEG monitors agree between themselves and with end-tidal concentration of sevoflurane (ETsevo) in relationship with the age in the pediatric surgery setting.
Bispectral index (BIS) and Entropy EEG monitors performance and utility is well established in adult general anesthesia.
Their utility is yet undefined in the pediatric population as age seems to affect their ability to track the cerebral hypnotic state in children.
Detailed Description
All patients monitored applying standard device for blood pressure, electrocardiogram and pulse oximeter for routine monitor of anesthesia in pediatric surgery. Bispectral VISTA monitor and Entropy monitor applied for monitoring the depth of anesthesia. The investigators will not assign any specific interventions to the subjects of the study.

Eligibility Criteria
Inclusion Criteria
- •physical status classification (ASA) I - II
- •general balanced anesthesia
- •mechanically ventilated with laryngeal mask
Exclusion Criteria
- •severe developmental delay
- •neurological disorders or receiving treatment with antiepileptic or stimulant
- •patients with preexisting lung or cardiac disease
- •airway abnormalities
- •marked skin sensitivity and conditions where the placement of the BIS and Entropy sensor or process of assessment would interfere with the surgery procedure.
- •patients receiving local anaesthesia, regional block combined with general anaesthesia
- •sedation administered by non anesthesiologists for invasive and noninvasive diagnostic or therapeutic procedures
Outcomes
Primary Outcomes
BISPECTRAL Index
Time Frame: BISPECTRAL index values from the induction moment to the awakening moment, 1/5 sec sampling rate, an average of 1 hours
The collected values of bispectral index and end tidal sevofluorane will generate a single prediction probability (PK) of agreement between bispectral index vs end-tidal sevofluorane along the whole period of anesthesia for each arm/group. Prediction probability (PK) is a statistical measure that is particularly suited to assess the performance of anesthetic depth indicators. It quantifies the correlation between observed anesthetic depth and indicator values. PK allows a simple interpretation and, as a non parametric measure, it is independent from scale units and assumptions on underlying distributions.
Entropy
Time Frame: Entropy values from the induction moment to the awakening moment, 1/5 sec sampling rate, an average of 1 hours

Secondary Outcomes
- BISPECTRAL Index Awaking(reported moment of awakening from anesthesia, an average of 1 hours after administration of Anesthesia)
- Entropy Awaking(reported moment of awakening from anesthesia, an average of 1 hours after administration of Anesthesia)
