The loss of sensibility and motor power or bodily movements.

A partial or total loss of the sense of pain, temperature, touch, etc.; that may be produced by disease or an anesthetic.

Local anaesthesia affects a limited area of the body; as opposed to general anaesthesia, which impacts the whole body. Although the term is used for loss of tactile sensibility, or of any of the other senses, it is applied especially to the absence of pain, as it is induced to permit performance of surgery or other painful procedures; analgesia.

The index of anesthesia history, Parts 1, 2, and 3.

1. The science of anesthesia.
2. A branch of medicine specializing in the use of drugs, or other agents, that cause insensibility to pain.

Anesthesiology may also be defined as "continuity of patient care" involving preoperative evaluation, intraoperative, and postoperative care and the management of systems and personnel that support these activities.

1. Insensible, deprived of sensibility.
2. An anaesthetic, or anesthetic, agent that produces insensibility, or anesthesia.

It is subdivided into general and local, depending on the type of action.

A person trained to administer anesthetics.

There is a major distinction between an anesthesiologist and an anesthetist. An anesthesiologist has a doctorate whereas an anesthetist does not.

An anesthesiologist is a physician (or, less often, a dentist) who specializes in the practice of anesthesiology while an anesthetist is a nurse, or technician, trained to administer anesthetics.

1. The process of rendering insensible with the induction of anesthesia.
2. Subjection to the action of anaesthetics.

To give anesthetics to, or to make a person, animal, area of the body, etc. unable to feel pain, touch, cold, etc.; to make insensible.

1. Absence of the sensibility to pain; absence of pain even with noxious stimulation (painful, pernicious, not wholesome); designating particularly the relief of pain without loss of consciousness.
2. A neurologic or pharmacologic state in which painful stimuli are so moderated that, though still perceived, they are no longer painful.

Beyond the pleasures and assurances of touch, there is always the looming possibility of pain. As a survival mechanism, pain warns our brains of danger and tells us to act to correct or avoid the cause.

Pain receptors, free nerve endings, are spread over a larger area than any of the other sensory receptors. They completely ignore light contact, and only fire up if the stimuli threaten to damage the tissue.

There are more pain receptors in the skin than other types of skin sensors, but they are not evenly distributed; for example, the neck and eyelids are densely covered, but there are few receptors on the sole of the feet and on the ball of the thumb, which is why the needle prick for a blood sample is often done on the thumb.

1. The paralysis of motion accompanied by the loss of motor power or sensibility.
2. Lacking proper movement
3. A combined sensory and motor paralysis.

1. A total or partial loss of the sense of pain, temperature, touch, etc.
2. A partial or complete loss of sensation, with or without the loss of consciousness; as a result of disease, injury, or the administration of an anesthetic agent; usually by injection or inhalation.

The phenomenon of being mentally alert (and terrified) while supposedly under full general anesthesia.

The patient is paralyzed, unable to speak, and totally helpless to communicate his/her awareness. Actual cutting pain may or may not be present.

Post-traumatic Stress Disorder (PTSD) occurs in approximately 50% of awareness victims, and of that 50%, it is suspected that 80% may never get over the trauma.

1. An instrument used to regulate the amount of an anesthetic administered.
2. An instrument for checking the degree of insensitiveness.
3. An instrument that determines the amount of pressure necessary to produce a sensation of touch.

1. A physician or, less often, a dentist who is specialized in the practice of anesthesiology, the branch of medicine involving the use of drugs or other agents that cause insensibility to pain.
2. A physician who specializes in the administration of anesthetics during surgery, birth labor and delivery, or other medical procedures.

An anesthesiologist has a medical doctorate whereas an anesthetist does not. An anesthetist is a nurse, or technician, trained to administer anesthetics.

1. The science of the proper administration of anesthetics and their effects.
2. The art and science of administering local and general anesthetics to produce the various types of anesthesia.

The active group of a molecule that confers the anesthetic or hypnotic effect.
