Clinical TrialThe minimum effective concentration of opioids: a revisitation with patient controlled analgesia fentanyl.
Whether patients titrate themselves to an individualized blood or plasma opioid concentration (the so-called minimum effective concentration or [MEC]) has been debated extensively. Nevertheless, there is consistent opinion that during patient controlled analgesia (PCA) patients balance acceptable pain relief against unacceptable side effects. This study sought to characterize fentanyl used by PCA with respect to MEC and factors influencing PCA use. ⋯ This study found evidence to support the concepts of an individual MEC and a therapeutic window of fentanyl used with PCA.
