Behaviour of nindex index during anesthesia on pediatric patients

The NINDEX index is a way to measure the anesthetic depth based on the EEF, commercially available since 2008 [1]. The NINDEX algorithm develops from a development database composed by EEG registries classified according to the Kugler anesthetic depth scale. It evolves within a cyclic adjustment process, which results in consecutive NINDEX versions developed over groups of data which are being more complete every day. The first and second versions of the NINDEX algorithm were developed based on adult patient registries. For the development of the 3.0 version, the development database was expanded by adding pediatric patient registries.
