AbstractNo pharmacokinetic data are available with respect to the plasma concentrations and fentanyl or sufentanil during epidural administration in children. This double-blind randomized study included 12 children (5-12 yr). Patients in group F were given an epidural loading dose of fentanyl 1.5 micrograms kg-1 and in group S sufentanil 0.6 microgram kg-1. Both groups then received a continuous epidural infusion of bupivacaine 5 mg kg-1 day-1 with either fentanyl 5 micrograms kg-1 day-1 or sufentanil 2 micrograms kg-1 day-1. An epidural PCA system was also given to the children (bolus: bupivacaine 0.2 mg kg-1 and fentanyl 0.2 microgram kg-1 or sufentanil 0.08 microgram kg-1). Maximal median concentrations of plasma (0.117-0.247 ng ml-1 for fentanyl and 0.027-0.074 ng ml-1 for sufentanil) were reached approximately 30 and 20 min respectively after the loading doses. These values were similar to those measured after 48 h.
