Patient-controlled analgesia (PCA) is a method of pain control that gives patients the power to control their pain. In PCA, a computerized pump called the patient-controlled analgesia pump, which contains a syringe of pain medication as prescribed by a doctor, is connected directly to a patient's intravenous (IV) line.

In some cases, the pump is set to deliver a small, constant flow of pain medication. Additional doses of medication can be self-administered as needed by having the patient press a button. Other times, a patient can control when he or she receives pain medication and does not receive a constant flow.
