Summary
In children, only a few studies have compared different modes of propofol infusion during a
total intravenous anesthesia (TIVA) with propofol and remifentanil. The aim of this study is
to compare Bispectral Index (BIS) profiles (percentage of time spent at adequate BIS values)
between four modes of propofol infusion: titration of the infusion rate on clinical signs
(TIVA0), titration of the infusion rate on the BIS (TIVABIS), target controlled infusion
(TCI) guided by the BIS either with the Kataria model (TCI KBIS) or the Schnider model (TCI
SBIS).
Methods: Children will be prospectively randomized into the 4 groups. In the TIVA0 group the
anesthesiologist is blinded to the BIS. In each group, the percentage of time with adequate
BIS values (45-55), the bias and imprecision will be calculated.
