Patients with tracheal intubation, tracheotomy, use of sedation or muscle relaxant drugs in the preceding 24 hours, status epilepticus, severe mental disorder, or forehead skin unsuitable for placement of the BIS sensor
Before the induction, unilateral BIS sensor
, that records the EEG waves, was secured on cleaned and dried forehead.
* 13.0-megapixel Auto-focus, Flash & BIS sensor
and a 2.0-megapixel front camera with full HD video recording ability
Used with the recently released BIS Pediatric Sensor or BIS Sensor
XP, the new BIS XP monitoring systems offer increased resistance to electrocautery artifact, enhanced performance in deep anesthetic states, and improved robustness to interference from noise sources, such as high-frequency motion artifact which occurs in the operating room and intensive care unit.
After skin preparation with isopropyl alcohol, a bilateral BIS sensor
was placed in a standard frontal bipolar montage with a ground electrode placed at the inner junction of the left eyebrow and four electrodes placed symmetrically on the participants' forehead (two on each temporal area and two above each eyebrow) allowing recording of four EEG channels.
An XP 2000 BIS platform was used and a paediatric Quattro BIS sensor
placed in accordance with manufacturer's instructions.
The BIS was measured using an Aspect XP 3.0 monitor connected to a BIS sensor
The BIS sensor
was applied to the forehead and right temporal area.
As asymmetry of BIS values was anticipated because of his unilateral intracranial lesion, bilateral BIS monitoring was performed using two paediatric BIS sensors
and two BIS-VISTA[TM] A-3000 monitors, version 3.20 (Covidien, Mansfield, MA, USA).
