Absence of normal sense of pain without loss of consciousness.
A drug that relieves pain without causing loss of consciousness, such as an aspirin.
Partial or complete loss of feeling or sensation, with or without loss of consciousness, primarily for the purpose of surgery or other medical procedure.

The branch of medicine concerned with reducing or eliminating pain or feeling in patients undergoing surgery, the delivery of a baby, or other medical procedures.

- Epidural Anesthesia
Anesthesia produced by injection of a local anesthetic into the peridural space of the spinal cord, frequently used during delivery, for surgeries below the waste, and for post-operative pain management.

- General Anesthesia
Anesthesia where the patient is rendered unconscious by administration of intravenous and/or inhalation anesthetics for the period of surgery. The patient's major bodily functions are closely monitored by a member of the Anesthesia Care Team. A breathing tube is usually required during general anesthesia.

- Local Anesthesia
Anesthesia where a small area is deadened by injection of a local anesthetic.
