AbstractFor several years, total intravenous anaesthesia (TIVA) has demonstrated many advantages that allow considering propofol anaesthesia as an interesting alternative in pediatric anaesthesia. TCI in children requires calculation and validation of pharmacokinetic (PK) models specifically adapted to the paediatric population. Several PK models based on a 3-compartement approach have been proposed in children: all these models, which integrate only weight as covariable, show increased distribution volumes with a wide interindividual variability. The particular importance to include physiological covariables, as age and lean body mass, to describe metabolic processes during growth and maturation in pediatric PKPD models is in agreement with recent allometric scaling works in children. However, as pharmacodynamic (PD) parameters are still debated in children, there is up to now, no PKPD model currently available for paediatric anaesthesia. Schnider et al.'s model, a model described in adults that includes numerous covariables, may be adapted and more efficient than the classical paediatric models to describe propofol-PKPD relationship in children over 5years. Whatever the model, a pharmacodynamic feedback such as the bispectral index may be useful to counteract interindividual variability in the paediatric population.Copyright © 2012.
