Popis: The pharmacokinetics of transdermal fentanyl were assessed in eight children aged 18-60 months, weighing 11-20 kg and monitored postoperatively in the intensive care unit. A patch, delivering 25 microg.h-1 of fentanyl, was applied for 72 h from the induction of anaesthesia. Plasma fentanyl concentrations were measured over 144 h. Mean (SD) peak concentration of fentanyl was 1.7 (0.66) ng.ml-1 and time to reach maximal plasma concentration was 18 (11) h. The elimination half-life was 14.5 (6.2) h, and the area under the curve for plasma fentanyl concentration (0-144 h) was 86.8 (27) ng.h.ml-1. Maximal fentanyl concentration was negatively correlated with patient age (r = - 0.71; p = 0.049) but not with body weight. These results suggest that the pharmacokinetics of transdermal fentanyl in children are similar to those in adults.
