Plasma protein binding is lower in children than in adults and increases with age. In neonates, sufentanil is approximately 80.5% protein bound, compared with 88.5% in infants (n=13) and 91.9% in children. The clinical relevance of reduced protein binding in neonates and infants is unknown.
The pharmacokinetics of sufentanil after administration of an intravenous bolus of sufentanil of 10-15 mcg/kg to pediatric patients undergoing cardiac surgery, as in adults, can be described by a three-phase plasma concentration curve (see tabel below). Pharmacodynamic differences due to differences in pharmacokinetic parameters may be greater if the unbound fraction is taken into account.

Watch out for vagotonia, muscle rigidity and respiratory depression. Be cautious if there is elevated intracranial pressure, myasthenia gravis.
In neonates there is a risk of overdosing or underdosing after IV administration due to the large variation in pharmacokinetics.
