pa·tient-con·trolled an·al·ges·i·a (PCA),

patient-controlled analgesia

Pain management A method for self-administration of narcotic-analgesics via a programmable pump; PCA is used for pain of terminal CA, postsurgery, angina pectoris, L&D Agents Fentanil, meperidine, morphine, sufentanil; PCA is delivered IV, subcutaneously or epidurally. See Pain.

(PCA) (pā'shĕnt kŏn-trōld' an'ăl-jē'zē-ă)
A method for control of pain based on use of a pump for the constant intravenous or, less frequently, epidural infusion of a diluted narcotic solution that includes a mechanism for the self-administration at predetermined intervals of the narcotic solution should the infusion fail to relieve pain.

patient-controlled analgesia

A method of pain control in which the patient cooperates. An intravenous drip is set up and the patient has a small control unit with a button which, when pressed, inserts a small dose of a drug such as morphine, into the infusion fluid. Overdosage cannot occur. A disadvantage is the need to urinate at frequent intervals.

Single injection femoral nerve blocks have been shown to reduce postoperative knee pain compared with patient-controlled analgesia. This results in a decreased amount of analgesia needed for the first 12-24 hours post surgery, sometimes up to 48 hours, allowing the patient to participate and tolerate rehabilitation efforts more easily.

From this study it is unclear whether these were differences related to requests for pain relief or staff perception and treatment provided but a similar team (Ng et al 1996b) examined ethnicity and patient-controlled analgesia. Asian, black, Hispanic and white patients self-administered similar amounts of opioid, yet black and white patients were prescribed higher doses than the Hispanic patient population.
