Intravenous Patient-Controlled Analgesia

Definition 1

A method of intravenous narcotic analgesic delivery that uses a pump or similar delivery system that allows the patient, or in the absence of the patient's ability to do so the patient's nurse or family members, to administer predetermined doses of analgesic as needed to maintain adequate pain control. This method allows the patient and/or family to have increased autonomy. Further, research has shown improved pain control and reductions in narcotics necessary to maintain pain control to be associated with this delivery method. (NCI Thesaurus)

Definition 2

A method of pain relief in which the patient controls the amount of pain medicine that is used. When pain relief is needed, the person can receive a preset dose of pain medicine by pressing a button on a computerized pump that is connected to a small tube in the body. (NCI Dictionary)
