title: Modifiers of Patient-Controlled Analgesia Efficacy in Acute and Chronic Pain.
abstract: Patient-controlled analgesia (PCA) is widely used as an effective tool for the treatment of acute and chronic pain. Its greatest advantage seems to be the easily achieved individualization of therapy, allowing optimum titration of analgesic dose to analgesic needs. This short review summarizes some predictors of PCA efficacy.
