BackgroundContinuous infusion of fentanyl for postoperative pain management is performed commonly. But the usage of traditional syringe pump or infusion pump sometimes makes medical staff confusing for its difficulties of handling. We have simplified the postoperative pain management system using the single-use continuous infusion device and the protocol for administration of fentanyl.MethodsSingle-use patient controlled analgesia (PCA) system was employed for the continuous administration of fentanyl. The amount of fentanyl was calculated by a concise chart. Numerical pain rating scale, frequency of bolus infusion and side effect were monitored by ward nurses.ResultsTwenty nine patients were included in this study, achieving good postoperative pain control. Seven cases of nausea, two cases of vomiting were observed as side effects, but no cases of over sedation or respiratory depression were reported.ConclusionsIt is concluded that good postoperative pain management is possible with single use infusion device safely.
