Randomized Controlled Trial Multicenter Study Clinical Trial
Postoperative pain control with a new transdermal fentanyl delivery system. A multicenter trial.
A new transdermal delivery system for fentanyl is available in two strengths: 70-80 and 90-100 micrograms.kg-1.h-1 (40- and 60-cm2 patches, respectively). Their short onset and 24-h drug delivery make them attractive for postoperative pain control. ⋯ Concern exists regarding the side effects of this this new transdermal fentanyl patch. Therefore, this new patch will need further research before it can be recommended as an adjunct in controlling postoperative pain.
