Analgesia Categories.

	Analgesia, Epidural - The relief of pain without loss of consciousness through the introduction of an analgesic agent into the epidural space of the vertebral canal. It is differentiated from ANESTHESIA, EPIDURAL which refers to the state of insensitivity to sensation.
	Analgesia, Obstetrical - The elimination of sensibility to pain, without the loss of consciousness, during labor, delivery, and possibly the postpartum period, usually through the administration of narcotic analgesics.
	Analgesia, Patient-Controlled - Relief of pain, without loss of consciousness, through an analgesic agent administered by the patient. It has been used successfully to control postoperative pain, during labor, after burns, and in terminal care. The choice of agent, dose, and lockout interval greatly influence effectiveness. The potential for overdose can be minimized by combining small bolus doses with a mandatory interval between successive doses (lockout interval).
	Audioanalgesia
	Neuroleptanalgesia - A form of analgesia accompanied by general quiescence and psychic indifference to environmental stimuli, without loss of consciousness, and produced by the combined administration of a major tranquilizer (neuroleptic) and a narcotic.
