AbstractPatient-controlled analgesia, which provides pain relief through self-administration of intravenous doses of opioids, is widely available and advocated as an effective analgesic modality. This report reviews published experiences with patient-controlled analgesia during labor and after cesarean delivery or major gynecologic surgery. Currently employed devices allow accurate record-keeping of drug use and permit patient mobility. No one device has been shown to be preferable. The form of administration most commonly described is infusion of morphine or meperidine on demand without combined continuous basal infusion. During labor, brief but progressively intensifying episodes of pain undermine the effectiveness of these devices when used intravenously. Compared with intramuscular administration of narcotics, patient-controlled analgesia after cesarean or major gynecologic surgery has been judged by patients to be more acceptable in achieving a balance between tolerable pain and sedation. Respiratory depression has been rare and is often attributable to misprogramming. Costs of these devices can be justified with frequent usage and are at least partially offset by more efficient use of nursing personnel for pain management.
