Brief summary
Determine the relation between PRST (pressure, rate, sweating, tears) score, skin conductance (SC) and Bispectral index (BIS) values during anesthesia
Detailed description
Probability of \>0 points in the PRST as a function of BIS and number of fluctuations in mean skin conductance (NFSC) will be recorded during the anesthesia.
Interventions
The bispectral index (BIS) and skin conductance (SC) monitors will be connected when patient will be positioned on the operating table. A BIS value greater than 60 will be considered an indicator of light anaesthesia. The SC monitoring will be achieved using the MEDSTORM AS 2005 monitor. Number of fluctuations in mean skin conductance (NFSC) of \>0.1 s-1 in a period of 15 s might be counted as a significant change and indicates an increase in the sympathetic outflow. General anaesthesia will be performed and laryngeal mask will be inserted. Blood pressure, heart rate, BIS, SC, and PRST (pressure, rate, sweating, tears) score will be recorded.

Primary
| Measure | Time frame | Description |
|---|---|---|
