Chapter 24 discusses patient-controlled analgesia (PCA), a conceptual framework of analgesia delivery which addresses inadequate analgesia. PCA is not limited to a single drug route or mode of administration. Patients have immediate access to opioids; analgesia management, at least in part, is under patient control. It also covers reasons for inadequate dosing, which include fear of addiction and the mistaken belief that addiction is related to the opioid dose, and the fear of opioid side effects, particularly respiratory depression.
